Electric cleaning device of dirty belt of post insulator of DC converter station

Abstract

The invention provides an electric cleaning device of a dirty belt of a post insulator of a DC converter station. The device consists of a base plate, an insulating frame, a pneumatic arm and the like. A whole system comprises three control loops such as a circuit, a gas circuit and a cleaning liquid loop. The device is electrified by a 220V AC power supply, can automatically walk, but needs to manually adjust the walk direction; and the insulating frame is divided into three grades, wherein a second-grade insulating frame and a third-grade insulating frame can be controlled to be automatically lifted up and down through an insulating rope to drive the pneumatic arm for cleaning to move up and down. The device is provided with a top rod, and the base plate at the lower part of the top rod compresses the ground, so that wheels on the base plate of the device are lifted without being contacted with the ground to prevent the base plate of the cleaning device from rolling front and back during working. In order to guarantee a cleaning mechanism to be capable of stably completing each cleaning action, four diagonal draw bars are arranged between the first-grade top part of the insulating frame and the base plate. The device has the characteristics of good safety performance, high automation degree and good cleaning effect.

Description

technical field [0001] The invention belongs to the field of high-voltage transmission lines, and relates to a dirty live cleaning device for pillar insulators of DC converter stations. Background technique [0002] my country's atmospheric environment is seriously polluted. With the development of national economy and industrialization, the quality of urban and rural air environment will deteriorate gradually in a long period of time. Therefore, anti-pollution flashover work is a long-term and important task. Taking effective measures to prevent the occurrence of large-scale pollution flashover accidents in the power grid and reduce the trip rate of pollution flashover is one of the important contents to improve the reliability of power grid power supply. Regular pollution removal is an effective means to maintain the actual anti-pollution ability of equipment. In order to ensure the safe and reliable operation of the DC converter station and prevent the occurrence of pollu...
