Product Description
General Description:
HXGN-12 Fixed Metal Closed Switchgear (Hereinafter referred to as "Ring Grid Cabinet")) is a three-phase AC converter with rated voltage of 10kV and rated power of 50/60Hz. It belongs to closed switchgear and is suitable for power distribution system, ring network power supply or do uble current radiation power supply system in factories, workshops, residential buildings and other places. It plays a role in receiving, distributing and protecting, and is also suitable foConditions of the environment.
Operating conditions: indoor.
Altitude: < 1000m.
Seismic intensity: no more than 8 degrees.
Pollution level: 11.
Ambient temperature: -15 °C - + 40 °C
Relative humidity: daily maximum average < 95%, monthly maximum average = 90%.
There is no danger of fire, explosion, serious pollution and c orrosion of metalAnd damaging the insulation of the gas and other bad places.
There is no place with violent vibration, turbulence and vertical gradient less than 80.
Product features
1. The switch cabinet body is assembled with 8MF section steel and separated into bus room, switch cable room and instrument room with metal partition.
2. The cabinet is of assembled structure, stable and reliable, and easy to extend and combine.
3. The load switch has a static contact insulation cover, which can effectively prevent arc short circuit accident in the cabinet and ensure the safe operation of the equipment.
4. The load switch has a unique metal valve and grounding structure. After the load switch is opened, the valve will automatically close and separate the fracture to ensure that there is no electricity in the switch cable room,Realize the purpose of separating from the live main bus compartment.
5. The load switch is usually side mounted, and the three phases are arranged in front and back, so the cabinet is small in volume and the floor area is reduced.
6. This product uses the compressed air load switch as the main component, and uses the compressed air principle to extinguish the arc, with stable and reliable breaking performance.
7. The load switch, grounding switch and fuse are assembled as a whole, with reliable locking device, meeting the requirements of "five prevention" function.
8. In order to optimize the operation of ring main unit, electric mechanism, communication module and other equipment can be installed to ensure the remote control and automatic management of power grid.
