What is the role of high-voltage circuit breakers? (1) control action. According to the needs of power system operation, some or all of the electrical equipment, as well as part or all of the line inputs or out of operation. (2) protection. When a part of the power system fails, it and the protection device, automatic device match, the speedy removal of defective parts from the system to reduce the power range, prevent the accident Henan high-voltage vacuum circuit breakers, protection systems of various types of electrical equipment is not Hubei damaged high-voltage vacuum circuit breakers to ensure trouble-free part of the security operation. Welcome to inquire buy! 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 loop light plate light, the signal out licensing display protection action, then the breaker opening refuse. 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 touch feet, 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) high-voltage vacuum circuit breaker, you should check whether the fault within the power range of the device, without fault should pull all shunt circuit breakers, circuit breaker on the power after, one by each branch circuit breaker test feed When the power supply to a shunt trip breaker again Jiangsu high-voltage vacuum circuit breakers, 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.), making it difficult to deal with on electrical or mechanical failure shall contact the dispatcher, as the disabled, turn maintenance treatment.
