我们选矿厂2#球磨机电动机是1台TDMK—400/6型高压同步电动机,由于励磁柜使用时间已久,结构老化,因而故障多,严重影响生产。1励磁柜基本结构和原理该励磁系统主电路部分是三相全控桥式电路,由6只300A可控硅及相关元件组成,它们在相应的脉冲控制下将交流电转换成直流电,供给电动
Our mill No. 2 ball mill motor is a TDMK-400/6 type high-voltage synchronous motor. As the excitation cabinet has been used for a long time, the structure is aging, so the breakdown is many, seriously affecting the production. 1 Excitation cabinet basic structure and principle The main part of the excitation system is a three-phase full control bridge circuit, composed of 6 300A SCR and related components, which in the corresponding pulse control will be converted into alternating current DC power supply, electric
