10 kV电压互感器裂纹故障分析及防范措施

Analysis and Preventive Measures of Crack in 10kV Voltage Transformer

分析10 kV配电室电压互感器裂纹故障的多种原因,确定了线路故障是造成互感器谐振的主要原因。此外,分析说明互感器质量及微机消谐原因,针对本电站的实际情况,确定加装一次消谐装置以防止互感器裂纹故障再次发生。

Based on the analysis of various causes of voltage transformer crack in 10 kV distribution room,it is determined that line fault is the main cause of transformer resonance.In addition,the analysis shows the quality of transformer and the reason of microcomputer harmonic elimination.According to the actual situation of the power station,it is determined to install a harmonic elimination device to prevent the transformer crack from happening again.
