Portable lead wire device

Abstract

The invention discloses a portable lead wire device, which mainly includes a control head, an insulating operating rod of a replaceable head and a switch handle. Rod connection, the switch handle is installed on the lower part of the insulating operating rod of the replaceable head, the switch handle is connected to the control cable, and the control cable is connected to and controls the control head through the working column on the transverse support rod. The present invention changes the test wiring mode from "manual wiring of overhead vehicle" to "mechanical automatic wiring" by controlling the wiring clip through the switch handle. In a word, the present invention has the characteristics of convenience, automation, and generalization of test equipment, and basically solves the upper wiring problem of primary equipment such as main transformers, switches, current transformers, and voltage transformers in the test. Therefore, popularizing and applying the present invention can improve the safety conditions and technical conditions of on-site operations, shorten the power outage time, and improve the safety and power supply reliability of work.

Description

technical field [0001] The invention belongs to the technical field of high-voltage testing, and in particular relates to a portable lead-wire device, which is used for test lead-wires of primary equipment such as transformers, switches, and voltage transformers. Background technique [0002] Due to the large number of main transformer test items, the staff need to change the wiring frequently during the test process, the wiring is highly repetitive and prone to electric shock hazards; at the same time, each test needs to go up and down the transformer bushing more than 20 times, which is labor intensive, especially for 220kV For the main transformer and above, the bushing on the high-voltage side is very high, and an elevated truck is required for wiring. Moreover, regardless of the scorching sun and high temperature in summer and the cold and windy winter, two testers need to change the wiring on the upper part of the transformer for a long time, and the working environmen...
