The invention further discloses a monitoring method of the high voltage breaker mechanical characteristic monitoring system. The monitoring system is advantaged in that a high voltage breaker operation state can be monitored, and problems of incomplete high voltage breaker monitoring and low precision in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of on-line monitoring of power transformation equipment, and relates to a mechanical characteristic monitoring system of a high-voltage circuit breaker. The invention also relates to a method for monitoring the mechanical characteristics of a high-voltage circuit breaker by using the monitoring system. Background technique [0002] High-voltage circuit breakers are the most critical primary electrical equipment for insulation and arc extinguishing in switching electrical appliances. When equipment and lines fail, the high-voltage circuit breaker can quickly cut off and isolate the fault to ensure the normal operation of non-fault users. And when the high-voltage circuit breaker fails, the faulty line or equipment cannot be cut off in the first place, which will cause incalculable damage to the power system and user equipment, and even bring hidden dangers to the safety of the staff. [0003] At present, due...
