Overview GN30-12 type rotary indoor hv isolating switch is a new type of rotating knife touch isolating switch, mainly in three phases of the reserve price were structured, make two plane, fixed two groups of insulator and contacts, through the rotating touch the sword, so as to realize the points off switch. GN30-12 D switch is in GN30-12 switch basis with grounding in the b of increased sword, can meet the needs of different power systems. This product design compact, take up the space is little, insulating ability strong, easy to install, its perbance meet the high pressure isolating switch and exchange grounding switch "requirement, rated voltage 10 KV ac frequency 50 HZ and the following indoor system, as in a voltage no-load condition, and the use of circuit points. But high-voltage switchgear and supporting the use, and also can be used separaby. 2. Type and meaning G N 30-12 D / 400 A / 630 A G: isolating switch; N: indoor type; 30: design serial number; 12: the rated voltage; D: take grounding device; 400: rated current; 3. Use the environmental conditions 1. The altitude does not exceed 1000 mm: 2. The ambient air humidity: cap + 40 ° c, floor-10 ° c; 3. Relative humidity: day average no greater than 95%, on average less than 90%; 4. The earthquake intensity not more than 8 degrees; 5. No serious dust, chemical corrosion and explosive material place 6. No regular violent vibration of the place. |
