Abstract: The new methods of high voltage circuit-breaker mechanical state diagnosis ponents of circuit-
breaker was presented in this paper, which based on the relationship of signal waveform eigenvalue and circuit-
breaker operating time sequence. Then, the system principle, system structure, operation effect and expansion test
of high voltage circuit-breaker mechanical state auto-diagnosis auxiliary system were introduced. it shows the
diagnosis algorithm theory based on characteristic value has universal significance to reflect spring operation
mechanism state.
