Description
technical field [0001] The invention belongs to the technical field of withstand voltage testing, and in particular relates to a mobile ultra-high voltage withstand voltage test device, which is mainly used for carrying out withstand voltage tests and insulation strength tests on various types of high-speed trains, EMUs, subway trains and electrical equipment. Background technique [0002] Due to its high test voltage and large test current, the UHV withstand voltage test device is usually designed as a traditional fixed structure. For various types of high-speed rail trains, EMUs, subway trains and electrical equipment for withstand voltage tests, ordinary withstand voltage test devices occupy a large area and cannot be moved, so they cannot meet the requirements of vehicles such as EMUs. Check usage requirements. Contents of the invention [0003] The purpose of the present invention is to provide a mobile UHV withstand voltage test device for the problems existing in t...
