Washing machine for post insulator

Abstract

The invention discloses a washing machine for a post insulator. The washing machine for the post insulator comprises a moving platform, a lifting rotary device and a washing head used for sweeping the post insulator, wherein the lifting rotary device is arranged on the moving platform, the lifting rotary device comprises a telescopic component used for controlling the washing head to rise and descend, and a rotary component used for controlling the washing head to swing in a left-and-right mode, a front-and-back adjusting device which is used for controlling the washing head to move forwards and backwards is arranged on the top of the telescopic component, an inclined lifting device which is used for controlling the inclination angle of the washing head, and controlling upward-and-downward lifting operation of the washing head is arranged at the front end of the front-and-back adjusting device, and the washing head is arranged on the inclined lifting device. The washing machine for the post insulator can be popularized and be used in a power grid system, can be serve as a dedicated anti-pollution flashover overhauling device, improves the level of standardized operation, improves overhauling quality, creates economic value for safe operation of a power grid, reduces safe production risks, and reduces safe production cost.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a post insulator cleaning machine. Background technique [0002] The external insulation of power transmission and transformation equipment will be polluted by industrial pollution or natural saline-alkali, dust and bird droppings. In dry conditions, the conductance of the dust on the surface of the post insulator is very small, which has little impact on the flashover voltage and has little effect on the operation of the power grid. less harmful. However, when the humidity in the air is high, especially under the weather conditions such as heavy fog, drizzle, condensation or melting snow and ice, the surface of the post insulator will be dirty and wet, and its surface conductance will increase sharply, which will cause a sharp increase in the leakage current on the surface of the insulator, thus As a result, the flashover voltage of post insulators is greatly reduced, and even flashover may...

AI Technical Summary

Problems solved by technology

[0004] (1) Maintenance personnel manually clean and wipe the insulators with a large workload, long working hours and high labor intensity;

[0005] (2) Maintenance personnel spend a long time climbing and working on heights, which poses a high safety risk;

[0006] (3) The reliability requirements of the power grid are high, and the time allowed for maintenance of substation equipment is getting shorter and shorter. Due to time constraints or shortage of personnel, the cleaning of post insulators is not thorough, pollution accumulates, pollution flashover occurs, and the safe operation of the power grid is endangered.
