HV Power Switches Product With 12kV Three Phases Porcelain Bushing
1. Features of Main Structure:
1.1 Type GN30-12Q/1000, 1250, 1600, 2000, 2500, 3150 or 4000 isolating switch is a new type rotary isolating switch. The main body of the isolating switch is fixed at two sides of a bottom frame by two groups of insulators, the two sides are fully separated from each other by an isolated plate connected at the frame. The opening and closing of the isolating switch are fulfilled by rotating the conducting pipes. On the basis of the original switch, an earthing knife is added to form a GN30-12Q(D) isolating switch to satisfy different requirements of switchgear boards. Because of the contacts are relatively assembled at the two sides of the isolated plate of the switch, it makes the two parts (with and without voltage) are fully separated from each other in a switchgear board, so the absolute safety for maintenance workers is guaranteed.
1.2 The conductive component consists of circular conductive pipe, a finger contactor and a contacting seat, and the finger contactor fixed on the contacting seat at two sides, and a magnetic locking plate is added to guarantee the dynamic and thermal stability of the switch while a short circuit trouble occurs.
1.3 A spherical contacting is applied for the contacting between the contactors and contacting seat, and line contacting is applied for the contactors and conductive pipe for decreasing the technological difficulty of assembly, and warrant of a good contacting.
1.4 CS6-2 operating mechanism can be used for the isolating switch, and the other operating mechanism self-designed is also used possibly.
