A substation contact grinding mechanism, grinding robot, system and method

Abstract

The invention provides a transformer substation contact grinding mechanism, a grinding robot, a system and a method. With the transformer substation contact grinding mechanism, the grinding robot, thesystem and the method adopted, the problem that live overhaul operation cannot be carried out during contact grinding, and the problem that operation tools cannot be replaced in real time for seriously-rusted disconnecting switch contacts can be solved, and transformer substation contact grinding efficiency is improved. The transformer substation contact grinding mechanism comprises a grinding part, a control part and a connecting part. The grinding part comprises a grinding head module and a cleaning module; the grinding head module is used for grinding a to-be-ground disconnecting switch disconnecting link contact; the cleaning module is used for cleaning the ground disconnecting switch disconnecting link contact. The control part is configured to receive the grinding operation ending signal of the grinding head module, switch to the cleaning module and start cleaning work. The connecting part is configured to connect the grinding part with a robot mechanical arm, and adjust an angle between the grinding part and the robot mechanical arm within a preset angle range so as to match the position of the to-be-ground disconnecting switch disconnecting link contact. Therebefore, the live working of the transformer substation contact grinding mechanism is realized.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to a substation contact grinding mechanism, a grinding robot, a system and a method. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The insulators of the open substation are exposed to the outdoor environment, and the disconnector switch needs to be closed and opened. In the power supply state, the disconnector switch needs to be kept in the normally closed state. The isolating switch switch is eroded by natural phenomena such as rain in the outdoor environment, and it is prone to rust at the contact contacts. In the long run, it will easily lead to poor contact of the isolating switch switch contacts, causing contact heating, and in severe cases, power failures. [0004] The inventors have found that the current contact grinding and maintenanc...

AI Technical Summary

Problems solved by technology

[0005] (1) Contact grinding is mostly a power outage maintenance operation, and live maintenance operations cannot be performed in areas where high power continuity cannot be arranged for power outage maintenance;

[0006] (2) Most of the equipment for contact grinding is single-operation mode with cleaning cloth or grinding head. It is impossible to replace the working tool in real time for the contact of the isolation switch with severe corrosion, and it is impossible to effectively polish the contact of the isolation switch.
