我公司现有35kV、10kV 输电线路的自动重合闸装置采用 DH-1型重合闸继电器。如图1所示。该继电器的信号灯用于监视电源保险、中间元件 ZJ 和控制开关的触点是否良好。然而,存在着信号灯泡易烧坏,附加电阻17R 过热造成接头脱焊,有的甚至烧焦等问题,因而严重影响了其他元件的正常运行,更不利于值班人员进行监视。为此,进行了综合分析和 My company’s existing 35kV, 10kV transmission line automatic reclosing device using DH-1-type reclosing relay. As shown in Figure 1. The relay’s signal light is used to monitor the mains fuse, the intermediate element ZJ and the control switch contacts are good. However, there is a problem that the signal light bulb is easily burned out, the additional resistor 17R overheats the connector to cause the solder joint to be desoldered, and some even burns. Therefore, the normal operation of other components is seriously affected, which is more unfavorable to the watchman on duty. To this end, conducted a comprehensive analysis and
