某光伏电站35 kV户外箱式变压器高压熔断器频繁熔断故障分析及整改措施

Fault Analysis and Corrective Measures for Frequent Fusing of the High-voltage Fuse of a 35kV outdoor Box-type Transformer in a Photovoltaic Power Station

某光伏电站35 kV户外箱式变压器高压熔断器在运行过程中多台次频繁发生熔断甚至烧蚀,给设备运行可靠性带来极大影响,通过对现场实际情况进行排查推断出其频繁故障的原因并提出相应的整改措施。

A 35 kV outdoor box-type transformer high-voltage fuse of a photovoltaic power station was frequently fused or even ablated during operation,which greatly affected the reliability of equipment operation.The frequent faults were inferred through the investigation of the actual situation on the site.And put forward corresponding rectification measures.
