Abstract

The invention discloses a circuit breaker action frequency counting device and method. The device comprises an open-type current sensor and a counter, wherein the open-type current sensor is electrically connected with the counter; a power supply line of an opening and closing coil of the circuit breaker penetrates through the open-type current sensor, and the open-type current sensor is used forcollecting a current signal flowing through the opening and closing coil of the circuit breaker of the power supply line and sending the current signal to the counter; and the counter is installed ona guide rail of a control cabinet of the circuit breaker, and the counter is used for obtaining a sampling value from the current signal and counting the action times of the circuit breaker accordingto the sampling value. The function of counting the action times of the circuit breaker in a non-intrusive manner is realized, the counting value of the circuit breaker can be remotely transmitted ina wireless manner, the field reading of inspection personnel is avoided, and the method has important significance for improving the state monitoring capability of equipment and improving the workingefficiency of the inspection personnel.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a device and method for counting the number of operations of a circuit breaker. Background technique [0002] High voltage circuit breaker is an important and complex high voltage switchgear. It can not only switch normal loads, but also eliminate short-circuit faults, undertake the dual tasks of control and protection, and play a key role in the safe operation of the power grid. The failure of circuit breakers often causes power grid accidents. In mild cases, it affects the normal power supply, and in severe cases, it causes large-scale power outages, personal accidents, and equipment damage. Therefore, the maintenance and repair of circuit breakers during operation is very important. The operating times of the circuit breaker, the cumulative number of breaking times and the short-circuit current value are important state quantities for evaluating the state of the circ...
