Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pulse capacitors, in particular to a multi-position adjustable high-voltage pulse capacitor. Background Art
[0002] In the power system, the insulation performance detection and fault point location of high-voltage cables are key links to ensure the safe and stable operation of the power grid. In order to accurately assess the health of the cable and detect potential problems in a timely manner, high-voltage pulse capacitors are needed to generate high-voltage pulse signals. These signals can propagate along the cable and reflect when encountering insulation defects or fault points, thereby helping technicians determine the fault location. Traditional high-voltage pulse capacitors are usually designed with fixed capacity and voltage levels, which means that they can only be used under specific test conditions. In order to meet the testing requirements under different voltage and capacity levels, power companies usually need to purchase, store and maintain multiple high-voltage pulse capacitors of different specifications, which not only increases costs, but also takes up a lot of storage space and brings inconvenience to on-site operations.
