摘要
针对某220k V变电站A相氧化锌避雷器故障情况,首先现场对A相避雷器进行绝缘测试和解体分析,对避雷器故障情况进行分析。其次结合现场试验和解体情况,认为本次故障是由于底座密封缺陷致使内部受潮,进而导致内部绝缘降低而发生放电。最后根据故障原因并结合现场生产情况提出了相应的防范措施。
As to a specific 220kV substation A phase ZnO lightning protector fault, firstly insulation test and disintegration test are made on the spot and analysis towards lightning protector fault has been made. Secondly, it was believed that this fault was due to base seal defect resulting to internal damp which led to the internal insulation reduction and discharge. Lastly corresponding precautions were put forward based on fault cause and onsite condition
