HXGN-12 Case Type Fixed High-Voltage Vacuum Ring Main Switch Cabinet
I. Purpose & Scope of Application
The HXGN-12 high-voltage vacuum ring main switch cabinet (called ring main unit for short) is applicable to the distribution system of industrial and mining enterprises, residence communities, high-rise buildings and schools as a power supply unit of indoor three-phase 12KV, 50HZ ring main and a terminal distribution equipment. It may break or close the rated load current and Transformer no-load current, and as well break or close the capacitance current of a certain distance of overhead line, cable or condenser bank. The load switch-Fuse composite apparatus cabinet is able to break the rated short-circuit current in a one-off way and is used for protecting the equipment, distributing and controlling electric power. II. Operating environment
Ambient temperature upper limit and lower limit are respectively 40°C and -25°C;
Altitude is not more than 1000m;
Relative humidity: daily average value should not be more than 95%, while monthly average value should not be more than 90%;
Places without fire and explosion risk and violent vibration, and corrosive and combustible gas, vapor and conducting dust in the ambient air and obvious pollution.
IV. Main technical parameters
VI. The following contents should be specified for ordering
1. Scheme of primary circuit and single wire system diagram;
2. Array diagram and layout plan of ring main unit;
3. Names, specifications and quantity of electric components installed in each cabinet;
4. Operation mode of load switch and type of motor power source and operating voltage;
5. Schematic diagram of ancillary circuit;
6. Type and specification of bus bar of the primary circuit;
7. Coating color of cabinet.
