摘　　要：新研制的并阻尼电阻消弧线圈自动跟踪装置 ,其并联阻尼电阻采用二次间接接入方式 ,它既能把单相接地电容电流有效地补偿掉 ,又能有效地防止电弧接地过电压。该消弧线圈的自动调谐 ,由信号调理、同时交流采样、多路转换。The automatic tracing device for parallel damping resistance arc suppression coil newly developed adopts the secondary indirect join-in method for its parallel damping resistance,which can effectively compensate single-ground capacitance and current and prevent effectively the arc from grounding over voltage.The automatic tuning of the coil is realized by the microcomputer controlled,which consists of the signal regulation,AC sampling,multiple-circuit changeover,A/C conversion and I/O modular.
