Description
技术领域technical field
本实用新型涉及输变电设备运行与防灾工具领域，特别涉及了一种GIS设备回路电阻测试辅助工具。The utility model relates to the field of power transmission and transformation equipment operation and disaster prevention tools, in particular to an auxiliary tool for testing loop resistance of GIS equipment.
背景技术Background technique
GIS设备由于其结构简单、维护方便等优点近年来在电网中广泛应用，由于GIS设备生产厂家众多，形式结构多样，对于GIS接地开关的接地侧与外壳不是绝缘的设备，不能利用回路上的两组接地开关合到待测回路上进行测量，就需要从进出线套管注入电流进行测量。此时，需要试验人员登高爬上GIS设备两侧进出线套管，人工安装测试线夹进行测量。由于GIS设备结构紧凑，与周围临近间隔距离小，感应电大或距离过近无法满足作业的安全距离，在装、拆测试线时极易发生工作人员触电、高空坠落和高空落物伤人的安全事故等原因使部分GIS设备无法进行测量。Due to its simple structure and convenient maintenance, GIS equipment has been widely used in power grids in recent years. Due to the large number of GIS equipment manufacturers and various forms and structures, the grounding side of the GIS grounding switch is not insulated from the shell, and the two circuits on the circuit cannot be used. When the group grounding switch is connected to the circuit to be tested for measurement, it is necessary to inject current from the inlet and outlet bushings for measurement. At this time, it is necessary for the test personnel to climb up to the inlet and outlet bushings on both sides of the GIS equipment, and manually install the test wire clamp for measurement. Due to the compact structure of the GIS equipment, the distance between it and the surrounding area is small, the induction current is too large or the distance is too close to meet the safe distance of the operation, and it is very easy to cause electric shock, high-altitude fall and high-altitude falling objects to injure people when installing and dismantling the test line. Accidents and other reasons make some GIS equipment unable to measure.
