Abstract

The invention discloses a power cabinet, which is characterized in that a power unit, a pulse control module and a heat dissipation fan all adopt drawer type structures, are pushed in and fixed on a framework of a cabinet body, and are fastened from the outer side of the framework, a bearing plate is arranged on the framework, the power unit is arranged above the bearing plate, the fan is arrangedat a corresponding position below the bearing plate, the power unit and the fan are aligned and fastened with an air duct opening in the bearing plate after being pushed in and fixed, cooling air enters from the lower portion of the cabinet body and flows to the upper portion of the cabinet body through the fan and the power unit, the power unit comprises power modules, a support capacitor and afirst composite busbar, the power modules and the support capacitor are electrically connected to the first composite busbar, and every two power modules are connected in parallel to form a U, V and Wthree-phase alternating current, and are connected to an alternating current output copper bar through a current sharing bar. According to the invention, the technical problems that the existing power unit cannot directly carry out power level and capacity expansion, modular and platform development of a power cabinet is inconvenient, the cost is high, and maintenance is inconvenient can be solved.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a modularized and serialized low-voltage universal inverter power cabinet. Background technique [0002] At present, the inverter system in the field of motor drive is widely used, mainly in oil drilling, marine equipment, mining machinery, metallurgy and other industries. As the core component of low-voltage transmission products, the general-purpose inverter power unit changes the characteristics of the input voltage by controlling the power module on and off, and plays the role of rectification and inverter. The domestic market is mainly occupied by foreign brands. ABB's ACS800 and ACS880 product series already have a relatively high market share, and have formed a voltage level coverage of 200V to 690V. Siemens' S120 series has book-type and chassis-mounted structures. Chassis-type modules include FX-JX and other different models. The voltage level is 660-690V, and...
