Wherein, described tool applications is in direct current and the charged defect elimination operation of transmission line of alternation current drainage plate.
Wherein, described tool applications is in exchanging 220kV and the charged defect elimination operation of 500kV transmission line drainage plate.
Wherein, described tool applications in direct current ± 500kV and ± the charged defect elimination operation of 800kV transmission line drainage plate.
Compared with prior art, the beneficial effect that the utility model reaches is:
1, be easy to carry;
Charged defect elimination wire clamp and drainage thread can be assembled before use, and defect elimination instrument has good integrality, assembled without carrying out on shaft tower.
2, easy to operate;
Charged defect elimination wire clamp adopts insulated handle to tighten operation and realizes to reliably the continuing of wire, without using spanner to tight a bolt.
3, handling safety;
Charged defect elimination instrument, through repacking, has installed insulated handle and drainage thread protective layer additional, can effectively hinder transmission line load current and pass through from human body surface.
4, highly versatile;
The exclusive fastening means of the charged defect elimination instrument long-pending wire of multiple section that can effectively continue, therefore the charged defect elimination instrument of a model can use on the transmission line of a plurality of electric pressures, has good versatility.
Accompanying drawing explanation
Fig. 1 is: the charged defect elimination tool construction of the drainage plate schematic diagram that the utility model provides;
Wherein: 1, charged defect elimination wire clamp; 2, insulated handle; 3, fastening handle; 4, drainage thread; 5, the terminal that continues.
