摘　　要：断路器的机械故障,极易引发更严重的破坏性事故,所以对高压断路器的运行状态检测就是很有必要的。本文基于HHT分析了断路器振动信号的特点,并得出了不同断路器状态、不同时刻的振动频谱。通过本文的分析可知,不同时刻测量断路器振动信号频谱结果会有一定差异,不同运行状态的断路器的合闸频域信号存在一定差异。The mechanical failure of the circuit breaker is easy to cause more serious destructive accidents,so it is necessary to detect the running state of the highvoltage circuit breakerThis paper analyzes the characteristics of circuit breaker vibration signal based on HHT,and obtains the vibration spectrum of different circuit breaker states and different momentsAccording to the analysis,the results of the vibration signal at different times,and the closing frequency domain signal of the circuit breaker in different operating states.
