The invention discloses a high-capacity power cabinet. The high-capacity power cabinet, comprises a power cabinet frame and a plurality of power units arranged in the power cabinet frame, wherein input and output long laminated busbars are arranged on the left side and the right side of the power units; an alternating-current input bus and an alternating-current output bus are arranged on the front side and the rear side of the inner bottom of the power cabinet frame side by side; a plurality of cooling water inlet pipes are arranged between the right side input and output long laminated busbar and the right side surface of the power cabinet frame; and a plurality of cooling water outlet pipes are arranged between the left side input and output long laminated busbar and the left side surface of the power cabinet frame. The capacity of the high-capacity power cabinet is large, the single cabinet can reach the megawatt level, the size is small, the power density is high, the modular design degree is high, the structure is compact, and the front disassembly and assembly are met, the installation and maintenance are simple and convenient, the capacity of expansion of the cabinet body is strong, and the whole cabinet layout is attractive in appearance, so that the power cabinet is suitable for engineering application.
Description
technical field [0001] The invention belongs to the technical field of electrical equipment, and specifically relates to a large-capacity power cabinet, which refers to a frequency conversion cabinet with a single cabinet capacity of megawatt level, small volume, high power density, high degree of modular design, and easy disassembly and maintenance. Background technique [0002] The frequency conversion cabinet is a cabinet widely used in the field of power electronics. It has become the currently popularized power drag method because of its good starting performance, speed regulation performance and energy-saving effect. In recent years, with the rapid development of the economy, the environmental protection requirements of the near-shore ports in the ship industry have become higher and higher. After the ship docks, the traditional power supply method is provided by an on-board generator, but when the generator is running at a low speed, the efficiency is low. The polluti...
