摘要
根据电压互感器工作原理,分析了10 kV母线PT爆炸故障的原因,并给出了相应的改进措施。除在电压互感器一次侧和二次侧加装消谐装置外,监测零序电压并进行谐波治理,可减小停电范围,保证生产的顺利进行。
This paper analyzes the reason of the 10 kV busbar PT explosion fault from the principle of voltage transformer operation,and the corresponding improvement measures are given.In addition to the harmonic elimination device installed on the primary side and the secondary side of the voltage transformer,the zero sequence voltage is monitored.At the same time,harmonic control is carried out to reduce the power outage range and ensure smooth production.
