General
In the whole set of equipment, it is called F-unit, which refers to the fuse switch unit. It is a two-position load switch with an independent grounding switch, trip device and load switch farm load switch fuse combination. The grounding switch of this unit device adopts dual mode, which can be grounded on both sides of the fuse at the same time.
Unless the grounding switch is closed, the fuse will not charge. At the same time, the dual grounding switches are mechanically interlocked, and the primary grounding operates the grounding of the two grounding switches at the same time.
