Lightning Damage of High Voltage Transmission LinesDuring the operation of high-voltage transmission lines, instantaneous overload will occurTotal trip accident, according to statistics, the main reason for this kind of trip accident isCaused by lightning, and frequent in lightning weather, complex terrain and soil resistanceThe probability of tripping accidents caused by lightning strikes in areas with higher rates will be higher. According to experience,It shows that in high-voltage transmission lines, the higher the transmission line is, the higher the voltage level isThe higher, the higher the probability of being tripped by lightning.Substation is the core component of the whole power system. First, equipment appearsFailure or accident will cause a large area of power outage in the region, thus affecting the national economyAnd people's living standards have been seriously affected.
