Conductive circuit overheating. Operation often occurs abnormal heat conductive loop phenomenon, mostly due to the static compression spring finger fatigue, characteristic deterioration isolation switch wholesale, static finger contacts and long-running unilateral increase in contact resistance caused. Run fingers because of static compression spring is compressed long-term, if the operating current is large, the temperature rise exceeds the allowable value, it will make it elastic variation, a vicious cycle, eventually leading to burning, which is the main cause contact heat . In addition, the contact silver coating process is poor, easy to wear exposed copper contact surface is dirty, the contact insert is not enough clamp bolt corrosion caused by the contact surface pressure is reduced and so is the cause of fever isolation switch contacts, contacts overheat how to deal with? A: The discovery isolation switch contacts, when the contact is overheating, the first report scheduling, seek to reduce or shift load, strengthen surveillance, and then processed according to the different wiring: (1) a dual bus connection. If a bus side switch overheated gas pressure isolation switch, by bus down the overheated isolation switch out of operation, maintenance outage. (2) single bus connection. It must reduce its load, strengthen surveillance and to take measures to cool down, such as conditions permit, as far as possible to stop using. (3) can bypass breaker with bypass breaker switching. (4) If the line-side disconnector thermal isolation switch price, its treatment and single-bus approach is basically the same, should be arranged as soon as possible maintenance outage. During maintain operation, should reduce the load and strengthen surveillance. (5) a half breaker may be open-loop operation. (6) for bus side isolation switch overheated contacts, contacts in the opened isolating switch, site inspection, meet live working safe distance, can bring out the bus side deflectors joint electrolysis, and then processed.
