Shenyang Electric Co., Ltd. Contact Weijing Li on public lightning discharge may occur between internal clouds or clouds, or between clouds ground; In addition, many large-capacity electrical equipment brought internal surge of power supply system (Chinese low-voltage power supply System Standard: Impact AC 50Hz 220 / 380V) and electrical equipment as well as lightning and surge protection, has become the focus of attention. Cloud to ground lightning strike by lightning once or several separate composition, each lightning carries a number of high amplitude, short duration of the current. A typical lightning discharge will include two or three times the lightning, each separated by about a twentieth of a second between the time lightning. Most of the lightning current is in the range of 10,000 to 100,000 amperes landing, its duration is generally less than 100 microseconds. Surge Protector (Surgeprotection Device), also known as high-voltage surge protector lightning, lightning protection of electronic equipment is indispensable safety device. Its role is to fleeing instantaneous power lines, the signal transmission line over-voltage limit within the device or system can withstand the voltage range and a strong impact of current leakage into the ground, so that the apparatus or system from impact damage surges. Current standard surge protector will be transported from the power supply to the plurality of electrical and electronic equipment on the circuit connection. If you cause a surge, the voltage exceeds the acceptable level, the surge protector will divert excess current to ground. Component surge protection principles in the most common surge protector, has called a metal oxide varistor (MOV), which consists of zinc oxide as the main body, adding more metal oxides, ceramics made by electronic polycrystalline semiconductor ceramic element surge protector for the transfer of excess voltage. As a core component, which determines the quality of a surge protector. Thunderstorm for: When Thundercloud ground discharge, a strong lightning current injection from the lightning hit point object, the lightning current peak of up to several tens to hundreds of thousands of security, thermal effects can be produced locally within the lightning point range up to 6000 ~ 10000 ° C temperature 50006000 Newton's powerful impact of mechanical force. Thunderstorm for the current generation of powerful, hot temperatures and severe impact of mechanical force, can cause structural damage to the object hit, damage, burning, melting, explosions and casualties. Lightning: lightning in the vicinity of the line equipment and facilities or the occurrence or non-direct-to-ground lightning discharge, the only discharge occurs between the clouds and the clouds. Lightning charge, and over-voltage induced in the power supply and data transmission lines and metal pipes, metal stents. When lightning strike to the building with a lightning protection and lightning air terminals along the top of the building (with lightning, lightning lines, lightning network or lightning), deflectors vent into the earth in the process, will lead referrals formed around a strong transient magnetic field, ranging from the disruption caused by electronic devices, data loss, malfunction or temporary paralysis; can cause severe breakdown components and circuit board burned lightning surge protection, so that the whole system is paralyzed . Conduction Ray: lightning discharge not directly to the building itself, but the arm outside the building cable discharge, lightning effects and over-voltage traveling wave at almost the speed of light diffusion along the cable line, threatening each electronic systems. Results Before hear thunder, data processing system, computer, instrumentation and control systems and other electronic equipment may have been damaged.
