低压电网三相不对称的危害及调整方法

介绍了低压电网三相负载不对称带来的诸多危害，譬如降低设备出力、使漏电保护器频繁动作、降低用户的电能质量、增加线路损耗，甚至烧断中性线威胁用电设备的安全。并分析了产生这些危害的原因。并为改善低压配电网的运行条件，提出了调整三相负载平衡的具体方法。

The Damage Caused by the Three-phased Load Unbalancing and Methods Adjusting Load Balance in the Low-voltage Distrubtion Network

This paper introduces the damage caused by the three-phased load unbalancing in the low-voltage distribution network, such as reducing equipment's output, making bleeder current protection often being on and off, reducing the quality of electric energy, increasing line power loss, even melting neutral wire and being dangerous to security of equipment. We assay the reasons for these damages. In order to improve the low-voltage distribution network, we also provide some methods adjusting three-phased load balancing.
