Abstract

The invention provides an insulator cleaning device and a cleaning method. The insulator cleaning device comprises a sampling assembly, a cleaning assembly and a controller. The sampling assembly comprises a voltage sampling piece and a current sampling piece, the voltage sampling piece is used for monitoring the voltage of a contact network, and the current sampling piece is used for monitoring the current passing through an insulator. The controller is connected with the voltage sampling piece and the current sampling piece, and obtains a voltage value measured by the voltage sampling piece and a current value measured by the current sampling piece. When the voltage value is within a preset voltage range and the current value is greater than a preset current value, the controller controls the cleaning assembly to clean the insulator. The insulator cleaning device provided by the embodiment can monitor the pollution degree of the insulator in the running process of a motor train unit and can clean the insulator in time before pollution flashover of the insulator occurs.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electric locomotives, in particular to an insulator cleaning device and a cleaning method. Background technique [0002] The locomotive top insulator is installed between the roof and the pantograph bracket of the catenary, and is an important high-voltage insulation support part of the roof, which ensures the normal current receiving of the pantograph and also ensures that there is a gap between the pantograph and the roof of the train. Sufficient insulation distance. [0003] If the insulator is exposed to the air for a long time, dirt such as dust will adhere to its surface. When the pollution is in a state of infiltration, the insulator will have a flashover breakdown, that is, a pollution flashover fault. In order to avoid pollution flashover of insulators, offline cleaning methods are usually used in the prior art, that is, the locomotive is parked in the garage, the caten...
