Abstract
Description
Technical Field
[0001] This invention relates to the field of disconnector switch contact cleaning technology, and more particularly to an automatic cleaning device for disconnector switch contacts in substations. Background Technology
[0002] A disconnector switch is a switching device mainly used for isolating power supplies, switching operations, connecting and disconnecting small current circuits, and without arc extinguishing function. Outdoor high-voltage disconnector switch contacts are exposed to the outside for a long time and are contaminated by dust, corrosive substances, sludge and other contaminants in the external environment. This causes severe dirt and oxidation on the contact surface, resulting in overheating of the disconnector switch contacts and seriously affecting the power supply quality.
[0003] Currently, the contact resistance of substation disconnector switches is increased due to the adhesion of contaminants such as dust, salt spray, and metal oxides. The carbonized layer generated by the electric arc during opening and closing operations reduces conductivity. Cleaning of substation disconnectors is mostly done manually, which requires power outages. Manual wiping results in uneven cleaning and poses risks associated with working at heights. Mechanical cleaning vehicles suffer from poor positioning accuracy, cannot adapt to various contact structures, and leave cleaning blind spots. Chemical cleaning agents pose corrosion risks, and laser cleaning equipment is too bulky for on-site deployment. Therefore, an automatic cleaning device for substation disconnector switches is proposed to address these issues. Summary of the Invention
