Keywords: SPD Power Supply System

First, the basic principles of lightning protection

Lightning and other strong interference on the communication system to the detriment and serious consequences arising therefrom, and lightning protection will be necessary. Lightning from the low-frequency components with very high permeability of the high frequency component. Mainly through its two forms, one is directly through the metal pipe or ground lightning conduction loss caused by equipment; One is the lightning channel and the discharge channel of the lightning electromagnetic pulse induced by a variety of coupling to the metal pipe or ground waves generated Chung, to the detriment of equipment. Most Lei Sun caused by this induction. For electronic information equipment, primarily from damage caused by lightning coupling of lightning electromagnetic pulse energy generated by the following three channels of the transient surge. Metal pipe channel, such as water pipes, power lines, Antenna, signal lines, aviation obstruction light surge generated by wire, etc.; ground channel, to call their counter; space channel, electromagnetic radiation energy group.

Surge channel for metal pipes and ground channel to counter the potential damage caused by electronic information systems major cause of most of its forms is to see to the detriment of the power line caused Lei Sun, it takes as the focus of anti-expansion. Lightning can strike as all-pervasive electronic information systems, lightning protection will be a systematic project. The center of a discharge lightning protection and balanced.

1. Blowdown is the lightning and the lightning electromagnetic pulse discharge energy through the earth, and should be consistent with the principle of hierarchy, that is as much as possible, as far as possible to the excess energy before the introduction of communication systems discharge into the ground; hierarchy is Lightning Protection established in accordance with different levels of the lightning energy to weaken. Lightning Protection District, also known as EMC Division, is based on people, things and information systems to lightning and lightning electromagnetic pulse of feeling Qiangdubutong to Huanjing into Jigequyu: LPZOA District, Ben Du district Ge objects may have been struck by lightning Zhijie Hence the special body may lead to go all the lightning current, no attenuation of the electromagnetic field in the region. LPZOB area, this area has been the object can not directly struck by lightning, but no attenuation of electromagnetic field in this area. LPZ1 area, this area has been the object can not directly struck by lightning, the current flows to the conductor than LPZOB area to further reduce the electric field effect on the overall attenuation and shielding measures. Follow-up of the mine area (LPZ2 area, etc.) If you need further reduced by the guidance of current and electromagnetic field, lightning protection zone should be the introduction of follow-up, the system should be in accordance with the need to protect the environment required for selection and the renewal of mine-area district requirements conditions. The higher number of protected areas, the expected voltage interfere with the lower energy and interference. In the modern lightning protection technology, lightning protection zone settings is important, it can guide us to shielding, grounding, and other electrical connections and other technical measures are implemented.

2. Balance is to keep the system does not produce enough to cause some loss of potential difference, that is the system where the environment and the system itself, the potential of all the metal conductor to keep the transient phenomena are almost equal, which is based on both real bonding of pressure. By a reliable grounding system, such as bonding with the metal wire and bonding device (SPD) to form a potential compensation system, in the presence of transient phenomena very short time, the potential compensation system can quickly be protected in system in which all the conductive parts of the region to establish an equal potential between these conductive parts also active conductors. Potential through the comprehensive compensation system that can form a very short period of time such as potential areas, the region may exist relative to the distance dozens of kV potential difference. Important is the need to protect the system located within the region, between all the conductive parts there is no significant potential difference.

3. Lightning protection system consists of three parts, each part has its important role, there is no alternative. External protection, the Jieshan Qi, deflectors, grounding body composition, energy can be most directly into the ground lightning discharge. Transitional protection, by the reasonable shielding, grounding, wiring component, can reduce or block access through the introduction of invasive sensors. Internal protection, from both pressure bonding, over-voltage protection component, can balance the system potential to limit over-voltage amplitude.

Second, the role of lightning protection devices and technical parameters

SPD, also known as equipotential connector, over-voltage protector, surge suppressor, varistor, lightning and other security devices for power line protection device known as the lightning protection lightning protection devices. Given the current characteristics of lightning induced damage, especially in the mine rectification of lightning protection, lightning protection devices protection program is based on the most simple, economic solution for lightning protection. SPD’s primary role is transient phenomenon, its potential at both ends of a line or limit the scope, the transfer of active conductor on the excess energy.

Into the underground discharge, pressure, etc. to achieve both an important part of bonding. SPD Some of the main technical parameters: Rated voltage, rated current, special approval from the string and Power SPD’s carrying capacity. The flux, the SPD’s ability to transfer lightning current to a thousand units, and open the open wave. SPD can be divided in function can prevent Thunderstorm for the SPD and the SPD against lightning. Anti-Thunderstorm for the SPD can be commonly used may be hit by lightning directly stroke line protection, such as LPZOA area and LPZ1 area at the junction of protection. Current waveform with 10/35μs testing and that its current capacity. Anti-lightning in the lightning protection devices are usually used to hit the line can not be Thunderstorm for protection, such as LPZOB area and LPX1 area, LPZ1 area at the junction of protection. 8/20μs current waveform with test and said its current capacity of response time, the SPD on the transient phenomena of a controlling time, and the wave nature of. Residual pressure, SPD restrictions on the ability of transient voltage phenomena, and lightning current amplitude and the wave nature of.

Third, the selection of lightning protection devices

Lightning protection device based on the desired effect you want, should focus on “where appropriate and reasonable to the installation of suitable lightning protection devices,” SPD selection is very important.

1. To enter the building between the various facilities lightning current distribution is as follows: about 50% of the lightning discharge flowing through the external lightning protection device into the ground, and another 50% of the lightning current in the metal material within the system distributed. This assessment model used to estimate the LPAOA area, LPZOB area and LPZ1 area for bonding the junction of the SPD’s current capacity and metal wire specifications. Where the lightning current to 10/35μs current waveform. In the metal material in the distribution of lightning current situation: the part of the lightning current amplitude depends on the distribution channel and some resistance and inductance, distribution channel is likely to be assigned to the lightning current in the metal material, such as power lines, signal lines, water pipes, metal frame and other metal pipes and other ground-level, generally only the value of their grounding resistance can be roughly estimated. In the case can not be determined, then a resistor can be considered equal, that is, the average distribution of the metal pipe current.

2. The introduction of overhead power lines and power lines may be Thunderstorm for hit, the access to the building of protected areas and exterior lines depends on the lightning current, lightning protection devices and the user side of the discharge branch line impedance and inductance. If the same inside and outside both ends of the resistance, the power line was assigned to half of the Thunderstorm for current. In this case, function must be used with anti Thunderstorm for the SPD.

3. Follow-up assessment model to evaluate LPZ1 area protection zone at the junction after the lightning current distribution. As the user side of the insulation resistance is far greater than the SPD discharge slip resistance of introduced lines and entered the follow-up of the lightning current lightning protection zone will be reduced, particularly in the numerical estimates do not need. General requirements for follow-up area of lightning protection lightning protection device at the current capacity of 20kA (8/20μs) below, without using Chase flow capacity of SPD.

Follow-up to the choice of mine area SPD should consider the energy distribution between the various levels and voltage matching is difficult to determine in a number of factors, the use of string and Power SPD is a good choice. String and style is based on modern lightning protection in many applications, such as distinguishing characteristics of level of protection concept put forward (as opposed to the traditional and the type SPD is concerned). The essence is by the energy and voltage distribution with multi-level electrical and filter up the effective integration of technology. String and type mine has the following characteristics: wide range of applications. Not only the routine application, but also a place for protected areas indistinguishable. Induced decoupling devices under transient over-voltage divider, delay effects, to help achieve energy match. Slow rate of rise of transient interference in order to achieve low residual voltage and long life and extremely fast response time.

4. SPD all the other parameters depend on the protected object level where the mine area, the operating voltage to install all the components in the lead circuit of rated voltage shall prevail. String and type SPD needs to pay attention to its rated current.

5. Affecting the distribution of lightning current electronic line of other factors: the transformer grounded resistor will reduce the electron current increases in the distribution. Increase in the length of power cable will reduce the current power distribution lines, and to have a few to lead a balanced current distribution. Short cable lengths and low impedance neutral line current imbalance will thus lead to differential mode interference. Power cable and multi-user access will reduce the effective impedance, resulting in distribution of current increases, even into the network of power supply in the state, the main flow into the mine temporary power line, which is most Lei Sun in the power line of reason.

Fourth, the installation of lightning protection devices

1. Power cord should be multi-level protection, multi-level protection is based on the mine area as the level of lightning energy progressively reduced (energy distribution), so that limits voltage levels complement each other, ultimately limit the over voltage device within the dielectric strength (voltage support). In the following cases, multi-level protection is a must: a 1 SPD or SPD failure of a road failure. SPD does not meet the residual voltage equipment insulation strength, cable length is longer in the building.

2. Almost all cases, the cable protection, at least should be divided into two or more, with a lightning protection device may also contain multiple levels of protection (such as string and type SPD). In order to achieve effective protection in the mine area set the corresponding interface of the SPD, SPD can be for individual electronic devices, or one with more electronic equipment space, all through the defense usually has a space shield mined areas of the wire through the mine area in the interface also has had SPD. In addition, the lightning protection device is limited, the general lightning protection devices and equipment line distance of more than 10m after the protective effect will deteriorate, because the SPD and the need to protect the cables between devices have reflective oscillation caused voltage, the amplitude and the line length is proportional to the load impedance.

3. In the use of power multi-level child lightning protection, if not pay attention to energy distribution, it may attract more lightning energy into the protected area. This requires the SPD should be based on the foregoing assessment model selection. Lightning protection devices are generally larger by lightning current, the higher the residual voltage characteristics, not by the energy level SPD after the distribution of lightning current flowing through a very small benefit voltage limit. Note that without considering the voltage response with low voltage and only choice for the final stage of lightning protection devices are dangerous.

With energy distribution and voltage to achieve the main points is to use two SPD inductance between the cable itself. Inductance cable itself has some obstacles to bury current and partial pressure of roles, so that more lightning current was assigned to the large discharge. General requirements 2 SPD around 15m in length between the cable, appropriate?? The situation within the cable. The length of cable on the branch line influence on the length of cable required, when the protection of ground and some distance from the protected cable (> 1m), time required cable length can be greater than 5m. In some cable itself is not suitable for use as decoupling?? Can use a special decoupling device, then no distance requirement.

4. Decoupling device is to achieve energy distribution and voltage with the key measures, the following materials can be used as decoupling devices: cable, inductance and resistance.

Power SPD series, and is a consideration of the energy distribution and voltage with the use of filters as a decoupling device SPD portfolio of applications for all occasions.

5. In some extreme cases, fitted with lightning protection devices but will also increase the possibility of damage to equipment, must stop; such situations. Lightning protection devices to protect a few lines, one line of SPD failure or slow response times. This may make common-mode interference into a differential mode interference and damage to equipment. This requires the need to implement multi-level protection and attention to the maintenance of lightning protection devices. Without regard to lightning protection zone, with the energy and voltage allocation by the random lightning protection devices installed, Biru just installed a SPD front-end equipment, since no pre-class protection strong lightning current will be attracted to the equipment front end, causing SPD residual voltage over equipment insulation strength. This requires the SPD to be installed in accordance with the principle of hierarchy.

6. In other cases, the wrong equipment installation will not effectively protected. Long connected line lightning protection, lightning protection devices work, the connection line from the inductance induced voltage will be high, add the device will still dangerous voltage level at the end of this issue SPD applications more obvious. To solve this problem is to use a short cable, but also to use two or more separate connections to share the magnetic field lines to reduce the pressure drop, in-line cable is bold no effect. If necessary, be protected by changing the line of wiring, so close to the bonding arrangements (access point) to reduce the cable length.

Mine output lines and input lines, grounding line near, laid side by side. This type SPD on the series and more serious effects. When the string and the power supply output line of mine (has the protection of the line) and the input line (not the protection line), ground close to the laying of lines within the sensor will output a transient surge, although smaller than the original strength, but still can be dangerous. To solve this problem is the input line, ground and output lines laid separately or vertical installation, to minimize the length of the parallel laying, the laying of the distance pulled.

SPD and the ground wire is not protected by the protection device is connected, that is to separate lightning protection and grounding. This will be the protection line and equipment protection in the time between the dangerous transient voltages, to solve this problem is to ground lightning protection device should be protected with devices connected.

Automobiles, which will be more affiliated to the Internet in the abreast future, could be accessible to hackers just as computers are now, two teams of computer scientists are admonishing in a cardboard to be presented next week.

“We authenticate the adeptness to adversarially ascendancy a advanced ambit of automotive functions and absolutely avoid disciplinarian ascribe — including disabling the brakes, selectively braking alone auto on demand, endlessly the engine, and so on,” they wrote in the report, “Experimental Aegis Analysis of a Avant-garde Automobile.”

In the paper, which will be presented at a computer aegis appointment next anniversary in Oakland, Calif., computer aegis specialists at the University of Washington and the University of California, San Diego, address that while avant-garde cars accept all-encompassing assurance engineering in the architecture of their computer ascendancy systems, little anticipation has been accustomed to the abeyant blackmail of hackers who may wish to yield over the networks that more ascendancy avant-garde cars.

The researchers, financed by the National Science Foundation, activated two versions of a late-model car in both class and acreage settings. They did not analyze the maker or the cast of the car, but said they believed they were adumbrative of the computer arrangement ascendancy systems that accept proliferated in a lot of cars today.

The advisers asked what could appear if a hacker could accretion admission to the arrangement of a car, said Tadayoshi Kohno, a University of Washington computer scientist. He said the analysis teams were able to authenticate their adeptness to avoid a advanced array of systems analytical to the assurance of drivers and passengers.

Wireless admission are more acceptable accessible in a advanced ambit of automobiles. For example, casework like the OnStar arrangement from Accepted Motors now address car position and analytic advice to the manufacturer. The arrangement can admittance communications amid cartage and emergency cadre in the accident of a blast and can accredit accustomed OnStar cadre to accidentally alleviate cars and stop them for purposes of annexation recovery.

“Taken together, all-over computer control, broadcast centralized connectivity, and telematics interfaces more amalgamate to accommodate an appliance software belvedere for alien arrangement access,” the advisers write. “There are appropriately abounding affidavit to amend the accompaniment of the vehicular computer security.”

Although there has been boundless belief about the role of software-controlled systems in the assurance crisis that Toyota has faced this year, the advisers said they were not exploring the accepted affair of the assurance of computerized systems, alone the issues accompanying to arrangement security.

Now Facebook is intensifying its efforts to expand its empire beyond its Web site; the company wants to turn scores of sites across the Internet into satellites where users will be able to interact with their Facebook friends, The New York Times’s Miguel Helft writes.

The coalition is led by Meebo, a company that offers a toolbar featured at the bottom of many Web sites that visitors can use to share articles, photos and other links with a variety of social networking services.The moves by Facebook and its rivals set up a battle for control over social interactions across the Internet.

“There is definitely a multiround fight that is going to be happening here,” said Jeremiah Owyang, a partner at the Altimeter Group, a digital strategy consulting firm.Similar to the Facebook “Share” buttons that are already popular with many Web sites, the “Like” buttons will make it easier for Web publishers to offer more social experiences, in essence allowing Facebook friends to enjoy those sites together.

The Internet search engine, after establishing itself as a destination for Internet queries, began syndicating its search box, and later its advertising system, across the Web through toolbars and partnerships. As Facebook becomes an ever more important source of traffic to other Web sites, the two companies’ rivalry is certain to sharpen.

The Like button will allow Facebook to keep a record of what a user linked to, providing the company with ever more data about people’s preferences.Facebook is also planning to offer a toolbar that Web sites will be encouraged to place at the bottom of their pages.

The toolbar will be easier for publishers to use and may encourage more users to log in. Facebook engineers were still working on the feature, and it was not clear if it would be introduced at the conference.It allows users to log in to Web sites with their identities from many social services, chat with friends from those services and select pieces of content from a site, like a photo, to share with those friends.
