For "rejecting" solutions to the problem are as follows: According to the accident phenomenon, to determine whether they are circuit breakers "rejecting" accident. When a table in mind the overall swing, voltmeter indicated value significantly lower Dongying high-voltage vacuum circuit breakers, circuit light plate light, the signal out licensing display protection action, then refused breaker opening. Determine the breaker failure, manual wind up immediately. Before yet to ascertain fault circuit breaker and main transformer power meter indicates the total value of the high-voltage vacuum circuit breakers hitting the foot of Linyi, abnormal sound strong, you should always pull the power breaker to prevent burn out the main transformer. When a power outage caused by a higher level of backup protection action, if the identification of a shunt protection action, the circuit breaker is not tripped, should pull the tripping of the circuit breaker to restore power circuit breakers superiors; if no action to identify each shunt switch (also may refuse to protect swap cards), you should check whether the fault in the power range of the device, without fault should pull all the shunt circuit breaker on the power circuit breaker after, one by one try to send each branch circuit breakers, when delivered When a shunt power circuit breaker tripped again, you can ascertain that the circuit breaker failure ("rejecting") circuit breaker. Then should not sending the breaker, but to restore the other circuits. Checking "rejecting" the circuit breaker can be quickly ruled out except in the case of general electrical faults (such as control supply voltage is too low, or the control circuit fuse is bad, blown fuse, etc.) outside the breaker, making it difficult to deal with on electrical or mechanical failure, should contact the dispatcher, as the disabled, turn maintenance treatment. Circuit breaker "Resist" treatment failures occur, "Resist" The situation is basically the 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.) Binzhou high-voltage vacuum circuit breakers, 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.
