发电机机端TV一次熔断器渐熔分析及不停机处理

Analysis of a TV Primary Fuse's Gradually Fusing of a Generator and Solutions in Non-Stop Generating

某电厂#2发电机机端TV一次熔断器出现渐熔现象,通过对TV二次电压降低、故障熔断器温度升高等现象的分析,现场技术人员锁定故障点并制定合理的继热措施,在不停机的状态下完成故障熔断器的更换。

Gradual fusing occurred at#2 generator′s TV primary fuse in a power plant.By analyzing such phenomena as TV secondary voltage reduction and temperature rising of the fault fuse,the technical personnel made sure the fault point and took reasonable relay and thermotechnical measures,and then completed the replacement of the fault fuse in the condition of non-stop generating.
