Abstract

A converter cabinet disclosed by the present invention at least comprises three sub-cabinets, each sub-cabinet comprises a cabinet body, and a first DC bus capacitor module, a rectifier power module, a second DC bus capacitor module and an inverter power module are at least arranged inside the cabinet body. The first and second DC bus capacitor modules are arranged horizontally and parallelly and are electrically connected via a conductor, the rectifier power module is located at the lower part of the first DC bus capacitor module, and a lower incoming line of the rectifier power module is connected with the first DC bus capacitor module via a conductor. The inverter power module is located at the lower part of the second DC bus capacitor module, a lower incoming line of the inverter power module is connected with the second DC bus capacitor module via a conductor, and the structures of the sub-cabinets are same and independent to form one phase.

Description

technical field [0001] The present invention relates to a cabinet, more specifically, to a converter cabinet. Background technique [0002] The medium-voltage high-power converter cabinets in the prior art are generally divided into rectifier cabinets, inverter cabinets and DC filtering parts, of which: 1. The rectifier cabinet is used to convert AC power into DC power; 2. The inverter The cabinet group is used to convert DC power into AC power; 3. The DC filter part is used to filter the rectified DC power, so as to obtain relatively smooth DC power and improve the quality of power supply. The DC filtering part is generally used as an independent cabinet group. The rectifier cabinet group and the inverter cabinet group respectively include three-phase main power parts, and the three cabinet groups are connected through DC busbars; It is not convenient to assemble and connect the two DC busbars. And for capacity expansion, cabinet groups can only be arranged in parallel, w...
