Hexafluoride load switch-fuse combination

Outline

TFLN36-12D, TFLRN36-12D indoor AC high voltage hexafluoride load switch and load switch-fuse combination electric appliance are designed and manufactured by our company, which digest and absorb foreign advanced technology and combine with the operation requirements of our country. The product has been fully tested and its performance meets the requirements of GB3804 3~63KV AC high-voltage load switch, GB16926 high-voltage load switch-fuse combiner, IEC 60265, IEC60420 standard requirements. The product has a “one in one grounding” three-station arc extinguishing chamber, reliable interlocking, strong break insulation. High degree, large climb distance design, special dynamic seal and fixed seal design, reliable sealing, is a new generation of high voltage switchgear equipment for urban power grid.

This product is suitable for three-phase AC 10kV, 50Hz electric power system. For industrial and mining enterprises, high-rise buildings, residential quarters, prefabricated substations and other places, it is used to break, close the load current, fault current, control and protection of the line and distribution transformers.

Superiority

The improved ring cabinets with this switch are suitable for higher altitude areas (below 3800m).

Design feature

The load switch and the combined electric appliance are composed of the same insulated torso switch body, the respective spring operating mechanism, the fuse contact seat and the fuse action impact tripping system.

The upper and lower body shells are injected with epoxy resin to form an inflated cavity. The common dynamic contact can be rotated in sequence to complete the three working states of “one in one and one ground”, and the electric closing and closing can be added to the basic manual spring operating mechanism for energy storage. The remote control operation is realized for the user to choose.

The front of the body box may be equipped with a SF6 gas pressure gauge with a position indicator for monitoring changes in SF6 gas pressure. The position indicating device is directly connected with the moving contact drive shaft, indicating the working position of the moving contact is absolutely reliable.

There is a safety diaphragm at the back of the body. When there may be some kind of accident inside the arc extinguish chamber and the pressure is too high, the overpressure gas can be released through the diaphragm to ensure personal safety.

Load switches and earthing switches, earthing switches and front doors (switches with this interlock for use in cabinets) have reliable mechanical interlocks.
