摘要
变频调速系统是WK-35电铲电气控制系统中的三大核心系统之一。文章介绍了WK-35电铲中的西门子变频器中各电子元件的功能,并根据经验讲述了变频器中IGBT的拆装方法及注意事项,最后简单叙述了变频器运行中的四大危害因素及维护方法。
The frequency converted speed control system is one of the three major key systems in the control system of WK - 35 electric shovel. The paper introduced the each electric component function in the Siemens frequency converter of the WK - 35 electric shovel. According to the experiences, the paper stated the IGBT dissembling and assembling method and noted items of the frequency converter. Finally the paper briefly stated the four risk factors and maintenance method of the frequency converter operation.
