Product details
Overview of FKRN12A-12D compressed air load switch:
FKRN12A-12D compressed air load switch, FKRN12A-12D series compressed air load switch fuse combination device, suitable for controlling and protecting power equipment such as transformers, cables, overhead lines, etc. in three-phase distribution systems of 12KV and below; Especially suitable for terminal substations and box type substations in urban and rural power grids. And it is applicable to the control and protection of ring networks and dual radiation power supply units.
The FKN12A-12D series compressed air load switch can switch between load current and overload current.
The FKRN12A-12D series compressed air load switch fuse combination can switch load current, overload current, and short-circuit current of the circuit.
Main technical parameters of FKRN12A-12D compressed air load switch
FKRN12A-12D compressed air load switch daily normal use environment:
1. Upper limit of ambient air temperature:+40C, lower limit -25C;
2. Sea level not exceeding 1000m;
3. The daily average relative humidity should not exceed 95%, and the monthly average should not exceed 90%;
4. The seismic intensity shall not exceed 8 degrees;
5. Places without fire, explosion hazards, chemical corrosion, and severe vibration;
6. Pollution level: II;
FKRN12A-12D compressed air load switch day main features:
1. Load switches, grounding switches, fuses, and mechanisms can be flexibly combined on a single frame, with a compact structure, small size, and easy installation;
2. The fracture surface is arranged in a direct acting manner, with high dynamic and thermal stability current parameters, and can be operated in one go;
3. Equipped with a static contact insulation cover, the ring main unit is structurally isolated, eliminating the need for phase to phase insulation partitions and broken insulation plugs, which can prevent arc short circuit accidents inside the cabinet;
4. The valve structure has a good protective performance, as the valve automatically isolates the fracture after the load switch is opened;
5. There is a reliable mechanical locking device between the load switch, grounding switch, and fuse, which meets the "five prevention" requirements;
6. There are two forms of electric operation with manual operation and AC/DC dual-use power supply, which facilitate the implementation of the "three remote" requirements of the power system.
