All-insulation shaking lightning arrester vehicle with plum blossom contact

Abstract

The invention discloses an all-insulation shaking lightning arrester vehicle with a plum blossom contact, belonging to electromechanical field and consisting of a circular pipe contact arm, an integrated insulator, a frame, a secondary plug, an arrester grounding bar, an all-insulation arrester, a chassis auxiliary switch, a copper braided strap, a DPC chassis and a chassis grounding bus. When in work, the banding plum blossom contact is connected on the circular pipe contact arm and is fixed on the frame by an integrated insulator, the all-insulation arrester is simultaneously installed on the frame, and then the installed whole frame is fixed on the DPC chassis to carry out work operation on the arrester. In the invention, the arrestor can be maintained and replaced in the case that circuits are not power off, and is made into a handcart type to enlarge the space of a cable chamber of power units, thereby separating the arrester with the cable chamber, ensuring personnel safety, and meeting the requirement of preventing personnel from entering electrified spacer regions.

Description

technical field [0001] The invention belongs to the electromechanical category, and relates to a hand-operated lightning arrester vehicle with fully insulated plum blossom contacts, in particular to a fully insulated manual lightning arrester vehicle with plum blossom contacts for maintenance and replacement of lightning arresters when the line is not powered off. Background technique [0002] In the current power supply electrical industry, the common installation method of lightning arrester is to adopt fixed type, which is extremely inconvenient to maintain in actual operation, and the fixed lightning arrester must be removed from the main circuit when carrying out withstand voltage test and replacement. The premise is that the power supply must be stopped, which not only wastes manpower and material resources, but also causes a lot of economic losses caused by power outages; another emerging solution is to make the arrester into a handcart type, which is better than a fix...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a fully insulated hand-operated lightning arrester trolley with plum blossom contacts, which solves the problem that the existing fixed lightning arresters are extremely inconvenient to maintain during actual operation, and the contact arm of the handcart lightning arrester is not very effective in terms of insulation. The process wastes manpower, the contact grounding area of ​​the tension spring type flat contact is too small, and the heat dissipation performance is affected after the moving contact and the static contact are engaged.
