摘要
研制了一种非电耦合直流传感器———磁耦合传感器。该传感器主要应用磁耦合原理,当直流系统发生接地故障时,该传感器可以准确地将故障信号检测出来,故障电流的检测范围为±5mA。该传感器具有体积小、测量准确、灵敏度高、抗干扰能力强、对直流操作回路无任何影响的特点,已成功地在线运行到发电厂、变电站的直流系统接地选线之中。
A kind of non-electric coupling DC sensor—magnetic coupling sensor is developed.The magnetic coupling theory is maily applied.The signal can be accurately detected by the sensor when ground fault occurs in DC system.The detecting range of the fault current is ±5mA.The sensor has some merits,for example:small volume,accurate measurement,high sensitivity,anti-interference and no effect on DC operating circuit.The grounded line of DC system can be successfully determinded by the sensor in power station and substation.
