近年来，随着城市老旧住宅小区改造工程的增多，电力台区三相负荷不平衡情况日益严重，不仅影响变压器的出力，甚至造成变压器烧毁事故。针对现行的人工调整法和电容补偿法调整三相负荷不平衡存在的弊端，介绍了实时动态调整法，该方法是在台区表箱处安装自动换相设备，由台区管理终端监控台区单相负荷电流，并根据设置的三相负荷不平衡率自动调整表箱负荷。通过对试验台区应用三相负载自动调平衡装置前后的效果对比分析，结果显示该装置的应用经济效益明显，在供电企业具有推广价值。

In recent years, with the increase reconstruction of Inner Mongolia old residential area, the three-phase load imbalance in power distribution area is becoming more and more serious, which not only affects the output of the transformer, even causes the transformer burning down. Real-time dynamic adjustment method is introduced in view of the drawbacks of the existing manual adjustment method and capacitor compensation adjustment three-phase load balance. The method is to install the automatic commutation equipment in the meter box area with the terminal management to monitor the single-phase load current of the distribution area, and according to the settings of the three-phase unbalanced load rate to adjust meter box load automatically, so as to achieve the automatic adjustment of three-phase load. Through the comparison and analysis of the effect of the three phase load balancing device in the test distribution area, the economic benefits are obvious, and the promotion value to the power supply enterprise is remarkable.
