摘　　要：本文应用带通滤波作信号予处理，以线圈电流、振动事件起始时间、位移、速度、加速度和振动信号能量作为特征量，得出一种高压断路器机械状态的人工神经网络监测方法。文中以CT-l弹簧操动机构的三种机械状态为研究对象，辨识结果准确灵敏。In this paper,with band-pas filter as sigual pre-processing method, coil current, time of appearance of vibration event, vibration displace ment, velocity, acceleration and signal energy as characteristic value,a monitoring methed for HV circuit breaker mechanical condition is built. Using CT-1 spring operating device for example,three kinds of mechanical condition are identified and result is accurate and sensitive.
