The correct order of operations isolation switch: (1) First isolation switch isolation switch in the operation, you should first check the appropriate circuit breaker in the off position really to prevent a negative Hera, co-isolation switch. (2) line stop, when the power Qingdao isolation switch, in order to be pulled together isolation switch. When a power outage, you must first pull Yantai breaker isolation switch, pull the line side of the isolation switch, then pull the bus side of the isolation switch. Power transmission and power operation sequence in reverse order. This is because when the malfunction occurred, according to the above procedure can reduce the scope of the accident, to avoid artificially expanded to make the bus accident. (3) operations, such as found seriously damaged insulator, isolating switch gear lever serious damage and other serious defects, may not operate. (4) isolation switch operation, there should be the duty officer at the scene-by-phase check points, closing position, over the same period, the contact depth contacts and other projects, to ensure the correct operation of the isolation switch, the correct position. (5) should generally be operated isolating switch in the main control room. When the remote control electrical operation failure in the field can be manually or electrically operated locally, but must seek permission from owners or technical person in charge, and in the case of on-site supervision of the situation can take place. (6) disconnectors, grounding switch and circuit breaker between the installation to prevent misuse of electrical, electromagnetic and institutions locking device. Switching operations, according to a certain order. If the locking device malfunction or disconnectors and earthing switches does not operate properly, you must strictly in accordance with the requirements of lockout condition check the appropriate circuit breakers, disconnectors position status only after checking the correct order to lift the lockout operation. Junction isolation switch webs overheating discoloration, indicating poor contact, the contact resistance, maintenance should open a connection point, the contact surface of the flat file and then sandpapering (but the switch should not remove the connecting plate zinc plated), then Tighten the screws and use a spring lock washer. Moving contacts exist beside hammer, rotating screw fixed contact, or slightly move the position of the support insulator to eliminate the next attack; three-phase different period, you can adjust the screws at both ends of the rod insulators Nantong isolation switch, in order to change its effective length to overcome. Contact between the contact pressure can be achieved by adjusting the clamping spring, and the degree of clamping feeler gauge to check availability. Between contacts generally coated with Vaseline to reduce friction and prolong life, but also to prevent contact oxidation. When the isolation switch is in the off position, the angle between the contacts opened or distance does not meet the requirements should be adjusted by rod insulators.
