Description
Technical field
The utility model relates to a kind of lightning protection devices of transmission line of electricity, and in particular to a kind of thunder and lightning induction type solid phase arc extinguishing
Lightning protection device.
Background technique
Transmission line of electricity lightning protection always is the important content of power department Thunder Protection, and lightning fault is still influence power grid
One of the key factor of safety.Transmission line of electricity is struck by lightning, and route is caused to be become attached to sub- flashover, the power frequency continued flow damage risen therewith
Insulator chain and fitting cause insulator chain to burn and blow conducting wire accident, and the prevention for being superimposed thunder is particularly acute.Traditional
" obstructive type " lightning protection mode, transformation pole tower ground resistance set up coupling ground wire and lightning conducter, installation leakage conductor etc.,
Due to its limitation, 50% lightning strike accident can only be solved.In recent years, electric in order to further increase the reliability that transmission line of electricity is powered
Power department prevents lightning strike accident using portable protective gaps in parallel are installed additional in transmission line of electricity.However in actual motion, between parallel connection protection
Gap has the obvious disadvantage that as follows:
Firstly, portable protective gaps in parallel are mounted on insulator chain both ends, it is the method by shortening insulator chain creepage distance
Play the role of preferential insulator chain breakdown when lightning stroke.Insulator chain creepage distance is shorted, and does not only result in electric system transmission of electricity
Integrally resistance to thunder level decline increases tripping rate with lightning strike to route, also results in power frequency dielectric level when electric system operates normally
Decline, it is invisible between improve portable protective gaps in parallel under temporary overvoltage and switching overvoltage miss breakdown probability.
Secondly, when transmission line of electricity meet be struck by lightning when, portable protective gaps in parallel preferentially because lightning stroke caused by overvoltage due to puncture, will
Lightning current leaks into the earth, to play the role of protecting transmission line of electricity and electrical equipment.However since portable protective gaps in parallel do not have
Arc extinguishing ability, cannot extinguish caused power frequency continued flow after insulator chain flashover, and electric arc long-time calcination between portable protective gaps will make
It is damaged at insulator chain, when serious, may cause transmission line of electricity broken string, while electric arc can cause ablation to electrode and reduce its guarantor
Protect performance.Finally extinguish electric arc by breaker to realize protection transmission line of electricity and equipment, is to sacrifice " trip-out rate " and " power supply
Reliability " exchanges the way of " low accident rate " for.
