The invention discloses a charging cabinet which comprises a cabinet body, a charger set, a storage battery monitoring module, a direct current monitoring module, an alternating current monitoring module, a control switch and an interconnection switch; the storage battery monitoring module, the direct current monitoring module, the alternating current monitoring module and the charger group are detachably installed on the cabinet body; the interconnection switch is used for connecting a first-section direct-current bus and a second-section direct-current bus; the direct-current monitoring module is used for being connected with the first-section direct-current bus; the charger group is connected with the first-section direct-current bus through the control switch; the alternating current monitoring module is used for being connected with an alternating current input device and is connected with the charger group through a double-path automatic switching device; and the storage batterymonitoring module is connected with the charger group and a storage battery group. According to the charging cabinet of the invention, the direct-current charger and each monitoring module are integrated, standardized design is carried out, and therefore, the charging cabinet is flexible in structure, compact and attractive, and has complete functions; and a direct-current charging screen can be subjected to core replacement without power failure of a direct-current system, so that online transformation of the charging screen cabinet of the direct-current system is realized.
Description
technical field [0001] The invention relates to the field of electric power technology, in particular to a charging cabinet, a replacement method thereof, and a DC power supply system. Background technique [0002] The chargers of the DC system are generally used for 10 years, and the failure rate is very high after that. However, the original products have been updated, and the spare parts have been discontinued. The chargers and other accessories need to be modified and replaced. The traditional transformation and replacement method is generally to replace the entire screen cabinet where the charger, AC / DC monitoring module and other accessories are located. [0003] The load carried by the DC system of the power grid enterprise is extremely important, such as DC oil pump, UPS power supply, relay protection device, etc. Generally, the DC system is not allowed to stop running. However, when replacing the overall panel cabinet of the charger in the traditional way, the DC s...
