摘　　要：为了克服传统电动机自耦降压起动的缺点,采用自耦降压起动柜前移和改变正常运行接触器逻辑位置两种方法,实现了一台自耦变压器起动两台电动机,达到了减少起动设备数量、提高设备利用率、节约经费的目的。通过对两种起动方法的组装调试,运行稳定可靠,证明设计是成功的。To avoid disadvantages of the auto-induction voltage-reduced start-up of conventional electromotors, this paper adopted two methods which were forwarding the autotransformer and changing the logical placement of working contactor to realize one autotransformer controlling two electric engines, so as to reduce the number of the start-up equipment and save the expenditure, rais- ing the equipment utilization. The two mehtods pass the assembling test and the improved system runs stably and reliably, which are proved to be successful design.
