The Lightning RTIP-Out Rate Calculation Of Arcing Gap Lightning Protection Based On State Variable Method

Lightning disasters to the national economy brought a huge loss, especially on power system in the influence of transmission lines of particularly serious。At present the measures for lightning protection general measures are:Set up overhead ground wire, installation lightning arrester and Reduce Reduce tower grounding resistance, erection coupling landlines, erect automatic reclosing device, adopt imbalance insulation, Adopt the effective neutral-point earthing and strengthen line insulation, but neither above what kind of lightning protection measures are have some shortcomings. Especially for below35kV tand its distribution network, Due to the low level of lightning insulation trip to happen often.. So Jet gases arcing lightning protection gap device is in clearance protection based on developed, this device is using explosions produce high-speed impact to arcing clearance flow strongly impact the arc and disturbance, make the arc of the spread of conductive ions quickly, and in this great disturbance impact, arc large scale from clearances electrode and been significantly stretched, until extinguished. The unit is not only arcing voltage, can safe, reliable and devices, fast response arcing in quick break current protection response time to arc extinguished.
