Circuit breaker "Resist" treatment failures occur, "Resist" yiyang high voltage vacuum circuit breaker, basically closing operation and reclosing process. The dangers of such a large failure, for example, in case of an accident requires emergency backup power input, if the standby power switch on the circuit breaker to refuse, it will expand the accident. Judgment circuit breaker "Resist" the causes and treatment generally three steps. 1) Check before closing time refused whether caused by improper operation (such as control switches let go too fast, etc.), and then combined with a control switch once again. 2) If the closing is still not successful, check the electrical circuits of each part, so as to determine whether faulty electrical circuit. Check the project are: closing control power supply is normal; closing closing loop control circuit fuse and the fuse is good; closing of the contactor contacts is normal; the control switch to the "switch on" position, look at closing core action is normal. 3) If the normal electrical circuit breaker is still not closing, then to mechanical failure, should be discontinued breakers, report scheduling maintenance treatment. After more than a preliminary examination can determine electrical connection, or mechanical failure. Breaker "misclassification" treatment failures and automatically trip the circuit breaker protection if not action, and in no short circuit tripping system or other anomalies, then the circuit breaker "misclassification." On the "misclassification" of judgment and treatment is generally divided into the following three steps. 1, according to the characteristics of the accident phenomenon Ganzhou high voltage vacuum circuit breaker that tripped the circuit breaker before the meter, a signal indicating normal, after tripping, continuous flash green, red light is off, the circuit breaker ammeter and active and reactive power meter indicates Hefei zero voltage vacuum circuit breakers, you can determine is a "misclassification." 2, check whether it is due to mistakenly touch, misuse, or mechanical vibration force caused by the "misclassification" circuit breakers, switches should be excluded at this time the cause, transmission immediately. 3, if the partial failure because of electrical or mechanical power transmission and not immediately, you should contact the dispatcher to "misclassification" deal breaker deactivate turn overhaul. Zhengzhou high-voltage vacuum circuit breakers, circuit breakers, power is supplied by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers.
