product description
The cable distribution box with SF6 load switch is composed of a load switch, a touchable cable connector and a stainless steel case, DFW-12/630A SF6 load switch is a fully insulated shell formed by epoxy resin casting. The inner cavity is filled with SF6 gas of 0.045 Mpa. lt has three stations of closing, opening and grounding, and has good arc extinguishing performance. The performance of the anti-pollution environment, if equipped with a fuse, can also break the short-circuit current.
The load switch has two operating mechanisms, manual and electric. When using the electric operating mechanism, remote control can be realized. There is a reliable interlock between the three stations to ensure strict operation according to the procedure: (1) When the load switch is in the closing position, the operating hole of the grounding switch is blocked, the grounding cannot be closed, and the front door of the ring network cabinet is locked. Live, can't open, (2) When the load switch isin the opening position, the arounding switch closing operation or the load switch closina operation can be performed. (3) Afterthe grounding switch is closed, the load switch cannot be closed, and the front door interlock of the ring network cabinet in thecable distribution boxis released, allowing the front door to open.
