The invention discloses a detection method and device for a high-voltage circuit breaker. The detection device comprises a detection unit, a collection unit and a diagnosis unit, wherein the detection unit is mounted on the high-voltage circuit breaker to detect mechanical state information of the high-voltage circuit breaker, the collection unit is connected with the detection unit to collect the mechanical state information detected by the detection unit, and the diagnosis unit is connected with the collection unit to diagnose mechanical faults of the high-voltage circuit breaker according to the information collected by the collection unit. Thus, the problem that the mechanical faults of the high-voltage circuit breaker are hard to diagnose timely in the prior art is solved, necessary basis is provided for maintenance of the high-voltage circuit breaker, and further, the high-voltage circuit breaker are avoided from accidents caused by operation faults.
Description
technical field [0001] The invention relates to the field of high-voltage circuit breakers, in particular to a detection method and device for high-voltage circuit breakers. Background technique [0002] Mechanical failure is the main failure type of high voltage circuit breakers. Early detection of defects and faults in the circuit breaker electrical control circuit and operating mechanism can not only avoid circuit breaker operation failures and avoid accidents, but also provide the necessary basis for circuit breaker fault maintenance. [0003] When the high-voltage circuit breaker starts to work, the opening and closing electromagnet coils are first powered on, and then the energy in the energy storage mechanism is released through a series of mechanical linkages, and then the moving contact is driven by force transmission and force direction control . The electromagnet coil current can reflect the collision between the movement of the electromagnet core and the trippi...
