一、对几种检漏继电器的简要分析1、Jу82型检漏继电器Jу82型检漏继电器的原理图(简化)如图1。它是现用比较多的一种漏电保护装置。其工作原理是:变压器T 二次电压经 D 整流后做为直流检测电源。经零序电抗器 L 和三相电抗器 SF,对三相电网的对地绝缘电阻进行直流检测。其检测电流亦通过串接在检测回路内的执行继电器 J,此检测电流将随着网路的对地绝 First, the brief analysis of several leak detectors 1, Jу82-type leakage detector Jу82 leak detection relay schematic (simplified) in Figure 1. It is now more of a leakage protection device. Its working principle is: Transformer T secondary voltage rectified by DC as DC detection power. The zero-sequence reactor L and three-phase reactor SF, on the three-phase network to the ground insulation resistance DC detection. Its detection current is also connected in series through the detection circuit in the implementation of relays J, the detection of current will be with the network of the Internet must
