Description

technical field

[0001] The invention belongs to a method for testing the state of a power system, in particular to a method for testing the comprehensive state of a circuit breaker. Background technique

[0002] With the development of the power system towards high voltage and large capacity, the power operation department has put forward an urgent need and higher requirements for ensuring the operation reliability of high voltage circuit breakers. Therefore, implementing condition-based maintenance on high-voltage circuit breakers and mastering their operating characteristics and changing trends can reduce premature or unnecessary blackout tests and inspections, reduce maintenance workload, reduce maintenance costs, improve the pertinence of inspections, and significantly increase power consumption. Reliability and economy of system operation.

[0003] Overseas research work on high-voltage circuit breaker state parameter testing has been carried out relatively early, and ...
