S-XCVFRM Miniaturized Vacuum Load Switch and Combination Apparatus
S-XCVFM series products adopt the integrated design of isolating switch, grounding switch and load switch, which are matched with XCVVZ vacuum circuit breaker produced by our factory, and have the characteristics of consistent depth of operating mechanism, depth of switch frame and height of bus connection. No matter the user selects circuit breaker or load switch or combined electricity, the connecting line between the branch bus and the main bus is not required to be made in the row, and the distance between the panels of different switching mechanisms and the cabinet doors can be ensured at the same time. If XCVVZ vacuum circuit breaker is installed in the cabinet, and the cabinet size is 550mm wide and X1800mm high X1000 mm deep, then the cabinet size can be 500mm wide X1800 high X1000 deep when installing this series of load switches or combined electrical appliances.
There are two operation modes of isolating switch and grounding switch in this series of products. One is that the isolating switch and grounding switch of the mechanism panel share an operation hole, the isolating switch and grounding switch are linked, and the height of the mechanism is 423mm; The other is that the mechanism panel has an isolating switch operation hole and a grounding switch operation hole. This mechanism is 72mm higher than the first one, disconnector and earthing switch shall be operated separately according to the interlocking procedure.
This series of products are recommended for paperback, and users can also install them on the side. The design concept of S-XCVFM series of products is to facilitate users, reduce the manufacturing cost of user cabinets, and create value for users.

The S-XCVFM knife gate is installed above the epoxy pole, and a square insulating plate is arranged at the rotation of the knife gate. After three-phase assembly, a square metal partition space is left, which provides great convenience for the metal armor isolation of the bus room and the cable room. The vacuum interrupter does not need to be vulcanized and is installed in the pole of epoxy resin. The movable end pull rod side of the arc extinguishing chamber is out, and the overtravel adjustment pull rod is upward, which effectively reduces the height of the epoxy pole.
Products for the isolation switch, load switch, grounding switch integration design. Isolation switch and grounding linkage operation can be selected (the isolation switch and grounding switch on the panel of this operating mechanism share one operation hole, hereinafter referred to as linkage operation), isolation switch and grounding switch can also be selected for separate operation (there are three operation holes on the panel of this operating mechanism: load switch, isolation switch and grounding switch, hereinafter referred to as three-axis operation). The mechanism operation panels and interlocking of the two operation modes are different, the linkage operation panel is only provided with the lower operation hole, and the three-axis operation panel is provided with the upper and lower two operation holes. The linkage operation mechanism is 72mm shorter than the three-axis operation mechanism, and is more compact and compact, which can fully meet the requirements of the five-prevention interlocking and protect the safety of the operator to the greatest extent.
The product adopts knife-gate isolating switch, the isolation fracture is clearly visible, and the insulation performance is safe and excellent.
The product adopts a compact modular spring operating mechanism, which can be inserted and installed as a whole or pulled out and disassembled as a whole. The performance is stable and reliable, the maintenance is simple, and the installation and replacement are convenient.
Unique design of the product: epoxy pole does not use solid sealing process, the arc extinguishing chamber does not need vulcanization, and the vacuum arc extinguishing chamber is directly installed, which improves the qualified rate of epoxy pole and arc extinguishing chamber installation.
