摘　　要：农村变压器输出单相负载设计之初,一般按用户分配配置。但是,随着农村现代化的不断推进,变压器输出单相负载的不平衡情况越来越严重,导致个别相电压过低。此外,用电设备尤其是感性负载在过低电压下工作时会增大电流来满足功率,加剧了电流的不平衡,并降低了输出电压。针对以上情况设计了一种智能换相控制器,配合现有的换相开关,可实现配电变压器输出负载的实时平衡匹配和平衡负载,以确保电压稳定,保证可靠运行。At the beginning of design,the output single-phase load of rural transformer is generally allocated according to users.However,with the continuous advancement of rural modernization,the imbalance of transformer output single-phase load is becoming more and more serious,resulting in individual phase voltage is too low.In addition,electrical equipment,especially inductive load,working under too low voltage will increase the current to meet the power,aggravate the current imbalance,and cause the output voltage to further reduce.In view of this situation,this paper designs an intelligent commutation controller,with the existing commutation switch,to realize the real-time balance matching and load balancing of distribution transformer output load,ensure the voltage stability,ensure the reliability of operation.
