66 kV干式空心电抗器短路故障整体参数试验研究

Study on Overall Parameters of Short Circuit Fault of 66 kV Dry Hollow Reactor

通过研究66 kV干式空心电抗器短路故障问题,根据现场检查及结构特点,来进行设备解体检查,发现包封层表面存在明显毛絮及鸟类排泄物,第7绕包层与第8绕包层有过火过烟的情况,且逐渐恶化,对层间及股间绝缘进行损坏,最终使得电抗器发生故障。由此提出相应的预防措施,保障设备的安全运行。

through the study of 66 kV dry hollow reactor short circuit fault,according to the field inspection and structure point,to inspect the equipment disintegration,found that the surface of the obvious wool and bird excrement,and the 7th and 8th coating have excessive smoke,and gradually deteriorate,the interlayer and strands insulation damage,finally makes the reactor failure.Therefore,the corresponding preventive measures are put forward to ensure the safe operation of the equipment.
