Suitable for outdoor three-phase AC distribution system with rated voltage of 12kV and rated frequency of 50Hz, it is used for opening and closing load current.
It is suitable for substation, industrial and mining enterprises, urban and rural power grids for protection and control, and urban and rural power grid automation distribution network and frequent operation places. There are many types of operation control switch for overhead line distribution system. FZW28-12 type vacuum load switch on column has the advantages of simple oil-free mechanism, reliable performance and no maintenance, and has been widely used so far. The product is combined with FDR fault detector or RTU remote control terminal device and other equipment to form a very simple distribution automation system, which can realize the automatic location of overhead line fault and automatic isolation of fault section. In order to update the existing distribution switchgear in our country, it is necessary to realize the transformation of distribution equipment characterized by oil free and automation.
