三相不对称负荷运行分析及解决对策

Operation Analysis and Solutions of Three-phase Asymmetric Loads

针对三相负荷不平衡情况,若不及时调整会给运行维护、用户电压质量、安全等方面带来直接的影响。结合生产实践,对不对称负荷运行状态下引起的各种损耗的增加、影响用户电压质量、影响设备正常运行等方面做了对比分析。同时有针对性地提出一些改进措施,以改善低压供电的质量确保配电变压器安全运行。

As to three-phase asymmetry, which is essential to operation, maintenance, voltage quality of customer and safety, the direct influence of loss increase, voltage quality and normal operation of equipment in the state of the operation of asymmetric loads are analyzed. Suggestions to improve the condition of three-phase asymmetry and low voltage supply quality are put forward, which ensure the safe operation of distribution transformer.
