Abstract

The invention provides a method and a device for detecting the operation state of a circuit breaker, and the method for detecting the operation state of the circuit breaker comprises the steps: collecting the operation state parameter values of the circuit breaker in operation, and enabling the operation state parameter values to comprise the temperature, the current of a load end, the distortioncontent, an unprocessed alarm and the number of switching-on and switching-off times; grading the collected operation state parameter values according to a preset operation state parameter value grading strategy to obtain operation state parameter grading values; obtaining a health degree value of the circuit breaker according to the collected operation state parameter grading value correspondingto each operation state parameter value; and determining the operation state of the circuit breaker according to the obtained health degree value. The operation reliability of a circuit comprising thecircuit breaker can be improved.

Description

technical field [0001] The invention relates to the technical field of electric appliance detection, in particular to a method and device for detecting the operating state of a circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current. It can realize automatic loss of voltage, undervoltage, overload and short circuit protection. It is widely used in the power control of various electrical equipment and the protection of feeder circuits. When the circuit is overloaded or short-circuited, the fault current is quickly disconnected, so as to effectively protect the electrical equipment. Therefore, the stability and reliability of the circuit breaker performance are of great significance to the safe operation of each electrical equipment. [0003] However, during the operation of the circuit breaker, with the accumulation of operating time and breaking times, the stability and reliability will decrease, t...
