The cleaning device comprises support mechanisms and cleaning mechanisms, wherein the support mechanisms are arranged at two ends of the insulator string, the cleaning mechanisms are arranged on the support mechanisms, each support mechanism comprises a fixed piece and a support rod, a fixed piece is arranged on each of insulator steel caps at the two ends of the insulator string, two ends of the two fixed pieces are connected by a support rod, and a plurality of cleaning mechanisms are arranged on the two support rods. The cleaning device has the advantages of high automation, comprehensive insulator cleaning and highcleaning efficiency and is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of anti-fouling flashover of insulators, in particular to a cleaning device for UHV tension insulator strings. Background technique [0002] High-voltage insulators, exposed to the air for a long time, are affected by environmental factors such as air pollution and natural dust. Solid, liquid and gaseous dirt particles are inevitably adhered to the surface, and generally have certain conductivity and hygroscopicity. Under the joint action of weather conditions such as fog, dew, rain and snow, the insulation level of the insulator will be greatly reduced, thereby increasing the leakage current on the surface of the insulator, so that pollution flashover may also occur under the working voltage, resulting in a power outage. With the development of electric power science and technology, the possibility of partial faults causing the collapse of the power grid is very small, but when a large number of lines trip ...
