An all-weather bushing lead-out line type earthing discharge tool of electric power equipment

Abstract

The invention discloses an all-weather bushing lead-out line type earthing discharge tool of a bushing lead-out line type electric power equipment. The tool includes a insulated support, an insulatedhandle, a slip-line resistor, a connecting rod and short-circuit ground wire, the top end of the insulating handle is connected with the bottom of the insulating bracket through a universal joint witha lock nut, A slide wire resistor is arranged in the middle of the insulating bracket, The two sides of the insulating bracket are respectively connected with the bottom end of the connecting rod through a spherical universal joint, the top end of the connecting rod is provided with plum blossom contact fingers, the terminal of the sliding wire resistor is connected with one plum blossom contactfinger, the other plum blossom contact finger is respectively connected with the sliding piece of the sliding wire resistor and the short-circuit ground wire, and the other end of the short-circuit ground wire is provided with a wire clip. The invention can greatly reduce the discharge operation time and improve the test efficiency.

Description

technical field [0001] The invention relates to an all-weather bushing lead-out wire type electric equipment grounding discharge tool. Background technique [0002] There are a large number of bushing and lead-out devices such as capacitors, reactors, discharge coils, and transformers in the power system operating equipment. The quantity of these electric equipments is large, and the stock of spare parts is large. [0003] According to the relevant power regulations, it is necessary to fully discharge the above-mentioned equipment during maintenance to ensure the safety of the operators. The grounding discharge method of the conventional bushing lead-out wire type power equipment is that the operator holds the bare metal wire clamp to the bushing end terminal. In this discharge method, the operator directly contacts the bare copper wire or copper terminal, and there is a danger of electric shock during the test process; the bare metal wire is directly short-circuited and d...

AI Technical Summary

Problems solved by technology

In this discharge method, the operator directly contacts the bare copper wire or copper terminal, and there is a risk of electric shock during the test; the bare metal wire is directly short-circuited and discharged, and the impact damage caused by the discharge current to the capacitor device cannot be controlled.
