FKN12-12D/T630-20 type indoor AC high-voltage load switch (referred to as FKN12-12D load switch) is a three-phase high-voltage switch with a rated voltage of 12KV and a rated frequency of 50Hz, which is used to divide the load current, closed-loop current, no-load transformer and cable charging current, and close the short-circuit current. Load switches equipped with ground switches can withstand short-circuit current.

Environmental Conditions Of Use
1. Ambient air temperature: -25ºC ~ +40ºC;
2. Poster height does not exceed 1000m;
3. The daily average relative humidity is not more than 95%, the monthly average is not more than 90%;
4. The earthquake intensity does not exceed 8 magnitude;
5. No fire, explosion risk, chemical corrosion and violent vibration places;
6. Pollution level: ‖
Structural Features
1. Load switch, ground switch, fuse and mechanism in a frame, flexible combination, compact structure, small size, easy to install;
2. The fracture is arranged in direct motion, the dynamic and thermal stable current parameter is high, and the operation is completed at one time;
3. With static contact insulation cover, the ring network cabinet is isolated in the structure, eliminating the phase-to-phase insulation partition and the fracture insulation board, which can prevent the arc short circuit accident in the cabinet;
4. With unique valve structure, after the load switch is opened, the valve will automatically isolate the fracture, and the protection performance is good;
5. There is a reliable mechanical locking device between the load switch and the ground switch and the fuse to meet the requirements of "five defenses";
6. There are two forms of electric operation with manual operation and AC/DC dual operation power supply, which is easy to achieve the power system: "three remote" requirements.
