summary |
|
The GN30-12 rotary indoor high-voltage isolation switch is a new type of isolation switch with a rotating contact blade. The main structure is to fix two sets of insulators and contacts on the upper and lower planes of the three-phase common chassis, and to achieve the opening and closing of the switch by rotating the contact blade The GN30-12D switch is an additional form with a grounding knife based on the GN30-12 switch, which can meet the needs of different power systems. This product has a compact design, small footprint, strong insulation capacity, and is easy to install and adjust. Its performance meets the requirements of GB1985-89 "AC High Voltage Isolation Switches and Grounding Switches", and is suitable for indoor power systems with a rated voltage of 10KV AC 50Hz and below. It is used as a switching circuit under voltage and no load conditions. It can be used in conjunction with high-voltage switchgear or used independently. |
