带电平板监测仪及其应用方法
摘要：
本发明涉及一种能够利用电压反馈(Voltage Feedback)方式消除(Eliminate)继电器开关(Relay Switch)的杂散电容(Stray Capacitor)的带电平板监测仪及其应用方法，测量平板部中配备有导电平板、接地表面体、介于导电平板和接地表面体之间的绝缘体，非接触电位计部安装于上述测量平板部的导电平板和接地表面体之间并对导电平板的电位进行检测，测定部对上述非接触电位计部所检测出的导电平板的电位进行测定或分流，电压反馈电路部对上述测定部所分流的导电平板的电位进行反馈并加载到继电器开关端。
摘要（英）：

Disclosed is a charge plate monitor for eliminating a stray capacitor in a relay switch by using a voltage feedback method, and an operation method thereof. The charge plate monitor includes: a measurement plate unit including a conductive plate, a ground surface, and an insulator provided between the conductive plate and the ground surface; a noncontact electrometer provided between the conductive plate and the ground surface of the measurement plate unit and detecting an electrical potential of the conductive plate; a measurement unit reading or passing the electrical potential of the conductive plate detected by the noncontact electrometer; and a voltage feedback circuit unit that feeds the electrical potential of the conductive plate passed by the measurement unit back, and applying the electrical potential to a terminal of a relay switch terminal.
