Description
Technical field
The present invention relates to arc extinguishing thunder resisting equipment technical field, specially one compression line span central authorities lightning stroke flashover goes out
Arc lightning protection device.
Background technology
Transmission line of electricity lightning protection is always the important content of power department Thunder Protection, and lightning strike accident remains affects electrical network peace
One of full key factor.Formula is pressed by China's existing overvoltage protection design specification regulation the air gap S (in terms of m): S=
0.012l+1 (m) calculates, and wherein l is span (unit m).This formula is to assume complete negative reflection and do not considering Tower Surge Impedance feelings
Derive under condition and form, draw and do not have the phenomenon that thunderbolt lightning conducter span is central.But in actual moving process, thunderbolt is lightning-arrest
The counterattack that line span central authorities cause causes shielding phenomenon to happen occasionally with thunderbolt wire span central authorities, and probability of happening is big, Yi Zao
Transmission line of electricity generation Lightning Over-voltage is become to cause flashover and insulator arc-over cause transmission line of electricity to trip on the spot.In recent years, defeated
The situations such as electric line height shaft tower, big span, scissors crossing, multiple-loop line, wire commutation generally occur, in thunderbolt lightning conducter span
Centre causes the accident such as tripping operation, lightning conducter broken string gradually to increase.The arc drawing thunder effect and mid span due to electric power line pole tower
Vertical effect, in a region not far along span direction distance shaft tower, it occurs the probability of shielding more than its areas at both sides
Shielding probability.When circuit is in mountain area, and adjacent two shaft towers are on two mountain tops, the span central authorities of wire are due to the most very
Height, is weakened by the shielding action on ground, and the windage yaw adding wire makes shielding angle strengthen, and wire span central authorities are anti-in this case
And become the hazardous area of shielding.During thunderbolt lightning conducter span central authorities, cause counterattack thus cause insulator arc-over and flashover on the spot.
During thunderbolt wire span central authorities, cause shielding also can cause insulator arc-over and flashover on the spot.When span central authorities in strong thunderbolt,
Huge lightning surge will be produced.Although big steepness thunderbolt thunderbolt intensity is little, but can produce huge impact thunder in moment
Electricity overvoltage, causes lightning stroke trip accident.In practical situation, there is big resistance in shaft tower and earth mat, during thunderbolt span central authorities, and thunderbolt
Impact characteristics cause huge induced overvoltage, also easily cause insulator arc-over.Analyze based on above, compression line span
