| 非独立式探测器 Independent detector 能探测剩余电流，并在该剩余电流达到设定值时输出一个报警信号（电信号或机械信号）。它必须与监控设备连用。 It can detect the residual current and output an alarm signal (electrical signal or mechanical signal) when the residual current reaches the set value. It must be used in conjunction with monitoring equipment. 最简单的非独立式探测器仅由一个剩余电流互感器、一个微功率继电器（如干簧管）组成。较完善的非独立式探测器具有报警电流设定、地址编码等功能，以集中方式供电。 The simplest non independent detector consists of only a residual current transformer and a micro power relay (such as a clarinet). The relatively perfect non independent detector has the functions of alarm current setting, address coding and so on, and supplies power in a centralized way. 由于没有声光报警，在现场不易及时发现是哪一路线路发生接地故障，使它的应用受到一定的限制。 Because there is no sound and light alarm, it is not easy to find out which line has grounding fault in time on site, so its application is limited. |
