Description

technical field [0001] The invention relates to a rectification device, in particular to a novel rectification cabinet for rail passenger car power generation vehicles. Background technique [0002] The three-phase AC460V power generated by the diesel generator of the 25T / G rail car power generation car, after the controllable rectification of the rectifier cabinet, outputs a DC 600V power supply for the load on the rail car. In order to meet the needs, the rectifier cabinet needs to have two sets Independent power supply system and rectification system, and the main circuit and control circuit need to be completely independent without interfering with each other. At present, rectifier cabinets mostly use three-phase fully-controlled thyristor bridge rectifier devices, and filter circuits and related control circuits are equipped on the DC side of the rectifier module. , protection circuit, etc. These rectification devices and circuits are all arranged in the same cabinet, r...

Problems solved by technology

[0002] The three-phase AC460V power generated by the diesel generator of the 25T / G rail car power generation car, after the controllable rectification of the rectifier cabinet, outputs a DC 600V power supply for the load on the rail car. In order to meet the needs, the rectifier cabinet needs to have two sets Independent power supply system and rectification system, and the main circuit and control circuit need to be completely independent without interfering with each other. At present, rectifier cabinets mostly use three-phase fully-controlled thyristor bridge rectifier devices, and filter circuits and related control circuits are equipped on the DC side of the rectifier module. , protection circuit, etc. These rectification devices and circuits are all arranged in the same cabinet, resulting in chaotic structure of the control circuit and power circuit, crowded space, and great potential safety hazards in daily inspection and maintenance.

In addition, because most of the rectifier cabinets are high-power components, the current passing through them is relatively large, so the components generate heat. In order to ensure and improve the heat dissipation effect of the rectifier cabinet, the upper air inlet and lower air outlet or side air outlet are mostly used at present, but It is still difficult to achieve the ideal cooling effect

At the same time, during the hoisting and transportation of the rectifier cabinet, the existing schemes mostly use wooden pallets, ropes, etc., which increase manpower and material resources and have great safety hazards
