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. Maintain operation during Tai'an disconnectors, 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, contact Huzhou isolation switch, isolation switch disconnectors after opened, the on-site inspection, meet live working safe distance, can bring out the bus side deflectors joint electrolysis Xiangfan disconnectors and then processed. Isolation switch conductive loop heat insulator flashover and seriously affect the safe operation of the equipment. You can replace the static compression spring finger stainless steel spring, stainless steel or galvanized high strength bolts and bolts with a torque wrench to tighten; adjust the contact insertion depth and clean the contact surface, Siemens or similar self-cleaning contacts. While using infrared temperature measurement technology on a regular basis to detect heat conductive parts of the case, identify problems in time.
