Abstract

The invention discloses a mobile high-frequency charging device. The device comprises a charging cabinet body, a plurality of high-frequency charging modules which operate in parallel are arranged inthe charging cabinet body, wherein at least one 220V high-frequency charging module and at least one 110V high-frequency charging module are arranged in the plurality of high-frequency charging modules; a back surface of the charging cabinet body is provided with a 220V DC output interface and a 110V DC output interface which are correspondingly connected with the 220V high-frequency charging module and the 110V high-frequency charging module, four corners of the bottom of the charging cabinet body are respectively provided with a pulley, and the top of the charging cabinet body is provided with a suspension ring. When the standby storage battery pack for transformer substation direct-current system transformation, storage battery maintenance, storage battery replacement or direct-currentsystem fault input is insufficient in electric quantity, the standby battery pack can be rapidly charged, the standby battery pack uninterruptedly supplies power to the direct-current power supply system, and the fault probability of a power grid is reduced.

Description

technical field [0001] The invention relates to electric power engineering technology, in particular to a mobile high-frequency charging device. Background technique [0002] The substation mobile high-frequency DC charging device is mainly composed of a variety of high-frequency charging modules, DC insulation monitoring modules, and man-machine dialogue modules. The charging module is mainly used for charging DC screen battery packs in substations. However, because the substation is equipped with a backup battery pack, when the DC system is transformed, the backup battery pack will be cut in to provide uninterrupted power supply for the DC power system when the battery is maintained and replaced. safe operation of the grid. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mobile high-frequency charging device, which can quickly charge the backup battery pack when the power of the backup battery pack put into ...
