Ring Main Unit 12kV 630A Medium Voltage Switchboard power grids, industrial and mining enterprises
Ring Main Unit 12kV 630A Medium Voltage Switchboard
In order to reduce the electric field strength, the isolation fracture was optimized and the shielding ring was added to the fracture. The electric field strength can be reduced to meet the requirements of insulation strength. The electric field strength of the insulated tie rod is significantly lower, which meets the requirements of the insulation strength.
Ring main unit is applicated to power distribution systems for power grids, industrial and mining enterprises, high-rise buildings, residential areas, hospitals, schools, parks, etc. are used for receiving and distributing electric energy. They are mainly used for ring network power supply and terminal power supply.
Why choose wetown:
- On the premise of ensuring the constant size of the cabinet and the general use of electrical components, the composition proportion of SF6-N2 mixed gas is optimized. On the premise of ensuring that the parameters of XGN new gas insulated metal enclosed switchgear meet or even exceed the design requirements, the usage of SF6 gas is reduced. Make the switchgear more environmentally friendly.
- Optimize the structure of the air chamber, add the shielding device of the three position switch, improve the structure of the lower wiring and upper wiring terminal of the arc extinguishing chamber, and redesign the insulation pull rod. In order to reduce the electric field strength, the isolation fracture was optimized and the shielding ring was added to the fracture. The electric field strength can be reduced to meet the requirements of insulation strength. The electric field strength of the insulated tie rod is significantly lower, which meets the requirements of the insulation strength.
- Develop an adjustable cabinet operation tooling. The tooling has the advantages of convenient operation and convenient fixing process of high-voltage cabinet body.
- In the process of product research and development, a movable roof device of switch cabinet is developed. Its advantage is that the roof will not be damaged in the process of removal, and it is easy to remove.
