变流器是列车进行电能转换的重要的部件,以满足牵引列车及牵引控制中对电能形式的需要。变流器是集中安装在一个变流器箱内,构成了一个整体,作为变流器箱安装于列车的底部。变流器箱一旦出现故障则导致整列动车无法运行,它的失效主要是内部电路失效引起,内部电路的失效可能由箱体变形导致,所以增强变流器箱体的强度,可以延长变流器箱的使用寿命,降低列车运行的故障,以此减少列车的维修成本,提高运营效率。
The converter is an important part of the train for power conversion to meet the needs of the form of electric energy in traction trains and traction control. The converter is centrally mounted in a converter box, forming a unit as a converter box mounted on the bottom of the train. In the event of failure of the converter box, the whole train can not run. The failure of the converter box is mainly caused by the failure of the internal circuit. The failure of the internal circuit may be caused by the deformation of the box. Therefore, the strength of the converter box can be increased and the current transformer can be lengthened The service life of the box, reduce the train running fault, in order to reduce the train maintenance costs, improve operational efficiency.
