Description

Technical Field

[0001] This utility model relates to the field of power equipment testing technology, and more specifically, to an integrated GIS equipment inductive withstand voltage testing device. Background Technology

[0002] GIS equipment needs to withstand normal operating voltage and various overvoltages (such as lightning overvoltages and switching overvoltages) during operation. If the insulation performance of the equipment is insufficient, breakdown, flashover, and other faults may occur under these voltage conditions, thus affecting the safe and stable operation of the power system. Withstand voltage testing can effectively verify the insulation strength of GIS equipment at different voltage levels and promptly detect potential insulation defects.

[0003] Traditional GIS equipment withstand voltage testing requires manual estimation of GIS equipment parameters, which is prone to errors and inefficient; moreover, it cannot provide real-time feedback on the equivalent capacitance of the GIS equipment, and reliance on preset parameters may lead to test errors.
