Description
Technical field
Field, more particularly to a kind of 500kV overhead power transmissions are administered the present invention relates to 500kV overhead transmission lines Anti-galloping
Circuit spring shock absorption type inter-phase spacer.
Background technology
At present, various Anti-galloping devices are employed in 500kV overhead transmission lines, compound alternate is common are
Every rod, the composite alternate interval rod can limit to a certain extent it is alternate wave electric discharge, but it is to suppressing gentle breeze concussion and time shelves
Less effective away from concussion.
Specifically, because the link length of existing composite alternate interval rod is substantially stationary, so the alternate gap of circuit
Regulated quantity it is smaller.So, when meteorological condition is severe, once circuit is waved, then existing composite alternate interval rod lacks
The approach of line oscillation energy is discharged less, it is impossible to quickly eliminate line oscillation；Meanwhile, between prolonged line oscillation is easily caused
The problems such as rod connects the bolt looseness on wire clamp and weighs circuit wounded；The regulated quantity for being additionally, since the alternate gap of circuit is smaller,
So existing composite alternate interval rod is not high to the suitability of circuit, easily causes gold utensil abrasion and rod type insulator plug is curved
Bent fatigue break.
The content of the invention
