摘　　要：目前普遍采用一台自耦变压器起动一台电动机,也有采用一台自耦变压器起动多台电动机的情况,为了兼顾设备成本及运行可靠性两个方面,提出了一种采用两台自耦变压器起动三台电动机的控制方法,并给出了主电路及其控制电路,该控制方式既降低了设备价格,又减小了占地面积。实际运行表明,设备能够长期稳定运行,可推广应用。At present,it is popular to use an autotransformer to start an electromotor,hut there is such a case that an auto- transformer can start several electromotor. In order to reduce the cost of device and ensure the device working properly,a new method of using two autotransformers to start three electromotor is put forward here and the main circuit and the control circuit are showed here. The method not only reduces the cost of equipment, but decreases the space. The result of running this system shows that the equipment can be operated stably for long time and is worth popularizing.
