某电站35 kV隔离式熔断器故障导致跳闸的分析与处理

Analysis and Handling of Tripping Caused by 35 kV Isolation Fuse Failure in a Power Station

随着碳中和、碳达峰目标的提出,我国新能源进入了高速发展的快车道中。光伏场站也随之发展,针对于云南多为山地的地理条件,导致光伏区较为分散,从光伏区的电能传输至升压站过程中,必然需要通过地埋与架空线路相结合,这也直接导致了上塔部分的隔离式熔断器在运行过程中出现各种故障,导致电能不能正常地传输。文章针对某光伏电站35 kV集电线路隔离式熔断器在运行过程中常见的故障进行分析和归纳,并提出对应的解决办法,旨在对光伏电站35 kV集电线路隔离式熔断器故障进行交流。

With the proposal of carbon neutrality and carbon peak goals,China's new energy has entered a fast lane of rapid development.Photovoltaic power stations have also developed accordingly.Yunnan is mostly mountainous in geographical conditions,resulting in scattered photovoltaic areas.The transmission of electricity from the photovoltaic area to the booster station inevitably requires a combination of buried and overhead lines.This also directly led to various faults in the isolation fuse of the upper tower during operation,resulting in the inability to transmit electrical energy normally.This paper analyzes and summarizes the common faults of 35 kV collector line isolation fuse in a photovoltaic power station during operation,and proposes corresponding solutions.
