Abstract

The invention discloses an electrifying insulating 360-degree cleaning brush for a transformer substation disc type suspension insulator string. The electrifying insulating 360-degree cleaning brush comprises an insulating operation rod (1), a cleaning brush bracket (2), an insulating pneumatic motor (3), an active insulating gear (4), a driving insulating gear (5), an insulating cleaning brush gear (6) and an insulating cleaning brush (7), wherein the insulating operation rod (1) is fixedly connected with the cleaning brush bracket (2); a driving device of the insulating pneumatic motor (3) is connected with the active insulating gear (4); a brace of the insulating cleaning brush (7) passes through the cleaning brush bracket and then is fixedly connected with the insulating cleaning brush gear (6). The electrifying insulating 360-degree cleaning brush can be used for cleaning a 360-degree plane of the disc type insulator at one time and solving the problem that an operator can only clean a 90-degree fan-shaped plane of the disc type suspension insulator by using a common cleaning brush and other 270-degree fan-shaped planes cannot be cleaned under the limitation of manual operation.

Description

Technical field

[0001] The invention relates to the technical field of power system equipment maintenance, in particular to a substation disc type suspension insulator string live-insulating 360-degree cleaning brush. Background technique

[0002] In recent years, with the development of industry and the deterioration of the atmospheric environment, long-term and large-scale smog has often erupted, and electrical equipment pollution flashover trips have frequently occurred in power grids across the country, seriously affecting the safe operation of the power system.

[0003] Pollution flashover of power equipment is the electrical porcelain surface of the equipment, which is contaminated by solid, liquid and gaseous conductive materials, which increases the surface conductance of the insulating layer, increases the leakage current, and generates partial discharges. Partial discharges on the surface of the insulating parts under operating voltage It develops into arc flashover, whic...
