Product Features |
The overall structure of the vacuum circuit breaker adopts the form of operation mechanism and arc-extinguishing chamber arranged one line before and after. The disconnector, fhe earthing switch and the circuit breaker are integrated to one unit, which has the same appearance and dimensions of FT8 load switch. The switch is designed to integrated side-installed structure, which includes installed frame, supporting insulating cylinder, load switch, disconnector, earthing switch and operation mechanism. 1. Miniaturization: Smaller width and height, which may realize the switchgear width of 500mm, the cable wiring height is not less than 650mm； 2. Integration: The integration design of the load switch, the disconnector, the earthing switch and fuse, the switch may he inverted to installed； 3. When the disconnector is in the state of open, the distance between isolating knife to earthing is still more than 125mm; 4. The switch may also be tested of mechanical characteristic after it is installed in the switchgear； 5. Perfect “five prevention” interlocking device, which has two operation functions of manual and motor. |
