FZN21-12/T630-20 and FZN21-12(R)D/T125-31.5 type Indoor AC high voltage load switch- fuse combination units appliances for three-phase AC 12kV, 5oHz power system, or with the complete power distribution equipment and loop-network switch cabinet , combined substation and othel ancillary uses, is widely used in urban network construction and transformation engineering, industrial and mining enterprises, high-rise buildings and public facilities ,can be used as ring power supply unit or terminal equipment, play power distribution, control and protection. Technical performance of the products meet the IEc publication 60265-1/FDis <<high voltage switches, Part 1: Rated voltages below 1kV over 52kV high voltage load switch>>, IEC60420<<High Voltage Ac load switch - fuse combination units>>; and cB1 926<<Ac High-voltage load switch - fuse combination units>>,GB3804<<3-63kV Ac high voltage switches>>reguirement.
Breaking with rated current, overload current (FZRN21-12D/T125-31.5 can short-circuit breaking current) and to prevent equipment missing running ability to switch a visible fracture of isolation, with combined installed capacity of the ground with the relevant switches and electrica spring agencies, to remote control.
FZN21-12D/T630-20 indoor high voltage vacuum Load break switch, suitable for powersupply network with rated voltage of 10kV three-phase AC 50Hz, used for breaking load current .
FZRN21-12D/T125-31.5 indoor high voltage vacuum Load break switch-fuse combination electrical appliance has large breaking capacity, safety and reliability, andlong electrical life, it can be operated frequently, the structure is compact, the volume is small, the weight is light, and the maintenance is basically unncessary. It can protect the transformer from overload and prevent the equipment from running out of phase. It has obvious isolation fracture. It can be equipped with grounding knife and electric spring mechanism with closing ability, and it can be remotely controlled.
FZN21-12 series high-voltage vacuum load switch is mainly composed of framer, disconnecting switch (current-limiting fuse of the combiner is in the disconnecting switch), vacuum switching tube, grounding switch, spring operating mechanism and so on.
This product has compact structure, small volume, long life, strong closing and breaking capacity, and easy operation and maintenance. The vacuum switch is equipped with a spring-operated mechanism, which adopts an electric motor (another manual) spring energy storage, and there are two types of closing methods: electromagnet closing and manual splitting and closing. The disconnecting switch, vacuum switch and earthing switch are interlocked with each other (mechanical interlocking) to prevent misoperation.
