Abstract

The invention discloses a heavy-load converter. A three-phase alternating current contactor in a middle chamber divides the converter into a bilaterally symmetrical structure; and four traction converter module mounting chambers, an auxiliary inverter module mounting chamber, a control box mounting chamber, a resistor mounting chamber, a terminal mounting chamber and an outlet are arranged on each side. The heavy-load converter can meet the working environment requirement in the field of electric locomotives and is convenient to mount and maintain, high in structure strength, and compact in internal structure; furthermore, the heavy-load converter is convenient to manufacture, assembly and maintain due to the modular design of all the internal components, and can meet the current requirements of heavy load and high speed and further meet the universal passenger and freight cars to a certain extent.

Description

technical field [0001] The invention relates to a converter, in particular to a heavy-duty converter. Background technique [0002] The converter is generally installed in the special electrical room of the rolling stock. Considering the limitation of the maintenance space of the electrical room, the converter must meet the requirements of easy wiring, convenient debugging, and easy disassembly and replacement of some common components. Due to the influence of vibration, shock and dust during the operation of rolling stock, the converter is required to have high structural strength, and the internal components and the whole cabinet have strong anti-vibration performance, which can meet the requirements of dust prevention. [0003] The utility model patent with the application number 201020108401.6 discloses a traction converter. This converter is mainly used for small and medium power locomotives, and its application range is mainly limited to DC traction systems of urban...
