Stroke track on-line monitoring device and monitoring method for circuit breaker

Abstract

The invention discloses a stroke track on-line monitoring device and method for a circuit breaker, the stroke track on-line monitoring device for the circuit breaker comprises an intelligent module, a vacuum circuit breaker, a closing coil, an opening coil and a stroke sensing unit, and the intelligent module and the vacuum circuit breaker are electrically connected with an external three-phase power supply at the same time; the intelligent module is electrically connected with the closing coil, the opening coil and the stroke sensing unit at the same time, and the closing coil, the opening coil and the stroke sensing unit are electrically connected with the vacuum circuit breaker at the same time; the device has the advantages that the stroke of the circuit breaker can be monitored, potential safety hazards of the circuit breaker can be found in time, accidents are prevented, and the reliability of the circuit breaker is improved.

Description

technical field [0001] The invention relates to the technical field of state monitoring of vacuum circuit breakers, in particular to an on-line monitoring device and a monitoring method for a circuit breaker's travel trajectory. Background technique [0002] The reliable operation of the power system is very important. As the most important high-voltage switchgear, the operation status of the vacuum circuit breaker will directly affect the safe and reliable operation of the power system. This requires that when the circuit breaker operates, it can reliably close or disconnect the working circuit. If the circuit breaker fails to close or open normally, it will seriously affect the stable operation of the power system and cause heavy losses. Therefore, the real-time online monitoring of the operating track of the operating mechanism during the operation of the circuit breaker becomes particularly important, which can provide reliable and necessary basis for the operation stat...
