Abstract

This application belongs to the technical field of substations, and provides an online monitoring device and method for a comprehensive alarm unit of GIS equipment in a substation. The device includes: a control module, an output module, an input module and a power supply module. The output module sends a test electrical signal to the monitored integrated alarm unit. If the control module receives the feedback electrical signal through the input module, it considers that the integrated alarm unit is working normally; Alarm. According to the state of the electric signal, the application can realize online monitoring whether the operation of the comprehensive alarm unit is abnormal, and it is convenient to directly modify and install the stock comprehensive alarm unit; the monitoring device can be fixed by screws and simple buckle wiring can be completed The installation in the GIS equipment control cabinet is simple.

Description

technical field [0001] The application relates to the technical field of substations, in particular to an on-line monitoring device, method, equipment, and storage medium for a comprehensive alarm unit of a substation GIS equipment. Background technique [0002] At present, with the rapid development of the power network, the number of substations continues to increase. At present, the state signal monitoring of GIS high-voltage electrical equipment in substations is mainly realized in two ways. One is to monitor each signal with an independent relay, and the other is to integrate all signals into a comprehensive alarm unit for combined monitoring. For GIS substations that have been put into operation for a long time, a large number of practical experience in operation and maintenance management shows that due to long-term electrified operation of the integrated alarm unit, the internal electronic components are aging and damaged, and extreme working conditions may occur whe...
