Disconnectors maintain a) cleaning porcelain surface dust, check out the porcelain enamel surface, damaged isolation switch, cracks and signs of flashover Ganzhou isolating switches, insulators iron, porcelain-binding site is secure. If the damage is serious, and should be replaced; 2) gasoline wipe blade contact or finger on the oil, check the contact surfaces clean, mechanical damage, oxidation and signs of overheating and distortion, deformation phenomena; 3) check contact or attachment blade is complete, no damage; 4) Check the connection busbar disconnectors and lead the circuit breaker is firmly Nanchang isolation switch, with or without overheating; 5) Check the flexible connection parts for impairment, broken Shares and other phenomena; 6) Check and clean the operating mechanism and transmission parts, and add the right amount of grease; partial distance 7) Check the live transmission and meets the requirements; locator and brakes are solid, the action is correct; 8 ) Check the isolation switch base is good, grounding is reliable. Isolation switch contacts, contacts overheat how to deal with? A: The discovery isolation switch contacts, the contacts overheating when first report scheduling, trying to reduce or shift load, strengthen surveillance, and then processed according to the different wiring: (1) double busbar. If a bus side switch overheated bus pass down the overheated isolation switch out of operation, maintenance outage. (2) single bus connection. Must reduce its load, strengthen surveillance, and to take measures to cool down, as conditions permit, as far as possible to stop using. (3) can be used with bypass bypass breaker breaker switching. (4) If the line side of the isolation switch overheating, its treatment with a single bus is basically the same approach should be arranged as soon as possible maintenance outage. During maintain operation, should reduce the load and strengthen surveillance. (5) a half breaker can be open-loop operation. (6) on the bus side isolation switch overheated contacts, contacts opened after isolation switch disconnectors Changsha, the on-site inspection, meet live working safe distance, can bring out the bus side deflectors joint electrolysis and then processed.
