Overview:
GN30-12 type rotary indoor high-voltage isolation switch is a kind of rotary contact knife type isolation switch, the main structure is on the three-phase common chassis, on the lower two planes, fix two groups of insulators and contacts, through the rotation of the contact knife, so as to realize the opening and closing of the switch.
GN30-12D switch is based on GN30-12 switch with the form of grounding knife, which can meet the needs of different power systems. It is easy to install and adjust, and its performance meets the requirements of GB1985-89 "AC High Voltage Disconnector and Grounding Switch", and is suitable for indoor power systems with rated voltage of 12 thousand volts AC 50Hz and below, as a circuit for splitting and closing under the condition of voltage and no load. It can be used in conjunction with high-voltage switchgear or separately.
