| description | The invention relates to the technical field of circuit breaker detection, and provides a method and a system for measuring and evaluating mechanical characteristics of gas insulated switchgear. The method comprises the following steps: testing a circuit breaker in the gas insulated switchgear according to an angular displacement linear camera system to obtain a multi-mode mechanical characteristic result; performing a reference test on the circuit breaker according to the high-voltage loop current and voltage acquisition system to obtain a multi-modal reference result; comparing the deviations of the two results to obtain a mechanical characteristic deviation vector; inputting the deviation vector into an evaluation channel to obtain an evaluation index; judging whether the index is lower than an expected value; and if so, generating an early warning signal. The technical problems that the measurement and evaluation of the mechanical characteristics of the circuit breaker are low in accuracy and poor in comp |
