Technical Research on the Thimble Type Low Voltage Line Fault Indicator

研制了一种用于低压线路上对线路故障和线损进行显示的故障指示器。所有故障信息通过LoRa上送到智能配变终端中,定时将电量上送到终端中,用于线损分析。该故障指示器分为室内和室外安装模式,适应所有新老配电柜、配电房。

A fault indicator for displaying line faults and line losses on low voltage lines was developed. When the voltage and current faults occur in the circuit,the indicator light on the indicator can be displayed. At the same time,all the fault messages are sent to the intelligent transformer terminal through the LoRa. The power is sent to the terminal to be used for the line loss analysis. The fault indicator is divided into indoor and outdoor installation modes to adapt to all new and old distribution cabinets and distribution rooms.
