Or the mode of winding carries out.
10kV overhead line outage line (including drainage thread) accident is more frequent, and disconnection fault 90% is taking fiery place.Needle
Each broken string is analysed in depth, predominantly the following:
(1), wire insulation wrecks and is not repaired, because the insulating layer of conducting wire not only acts as insulating effect, also
Carry corresponding tensile capacity, conducting wire for a long time under force especially exposed conducting wire of hot season in midsummer easily by
It stretches, conductive wire cross-section, which changes, generates gap sparking so as to cause contact surface, causes to break.
(2), the differentiation (lead conductor diameter deviation) of conducting wire.Such as main line is JKLYJ-185-10kV, T connects conducting wire
For JKLYJ-95-10kV, traditional parallel groove clamp causes contact point is bad to cause to take fiery broken string due to the difference of conducting wire.Even if adopting
It can not be avoided taking fiery phenomenon caused by this poor contact with c-type wire clamp.
(3), it is connect using wound form T.Be mainly manifested in T connect fastening be directly wound with the binding wire of 6mm2 to 10mm2
Take fire.This is taken fiery mode advantage and is to draw materials conveniently, easy construction.But disadvantage can only be directed to low capacity short-term operation load, long
Time operation binding wire is easy feedingization loosening poor contact and sparking is caused to break.
The occurrence of above broken string, especially directly threatens health operation and the people of equipment in city densely populated place location
The security risk of member's electric shock.For the generation for preventing broken string and personnel's electric shock event, power grid operation is influenced, spy drafts this project
Prevent the generation of similar situation.
