一种开关柜电气绝缘故障在线监测装置及方法
摘要：
本申请公开了一种开关柜电气绝缘故障在线监测装置及方法，分别采集流入开关柜内的电流信号、开关柜母线相对地电压信号和开关柜入地高频电流信号；然后这些信号进入示波器中显示出电流信号的波形和电压信号的波形，再由处理器对电流信号的波形和电压信号的波形进行处理分析，进一步判断开关柜内是否发生故障，故障的类型以及故障发生位置。本申请实施例提供的装置及方法，可以根据故障发生时电流及电压的特征及波形变化的特点，判断出开关柜内的故障情况，为维持人员提供很好的维修指导，避免产生不必要的损失，同时也节省维修时间。
摘要（英）：

The invention discloses a switch cabinet electrical insulation fault online monitoring device and method. The current signal flowing into the switch cabinet, switch cabinet bus ground voltage signal and the switch cabinet high frequency current signal into the ground are respectively acquired; and then the signals enter into the oscilloscope and the waveform of the current signal and the waveformof the voltage signal are displayed, then the waveform of the current signal and the waveform of the voltage signal are processed and analyzed by the processor, and the fault in the switch cabinet, the type of the fault and the fault location are further judged. According to the device and the method, the fault situation in the switch cabinet can be judged according to the characteristics of the current and the voltage and the characteristics of the waveform change when the fault occurs so that great maintenance guidance can be provided for the maintenance personnel, unnecessary loss can be avoided and the maintenance time can also be saved.
