Main Features Of Gis Gas Insulated Switchgear

With the development of economy and society, the use of gis gas insulated switchgear is increasing. In recent years, gas-filled switchgear that is miniaturized, unaffected by the external environment, maintenance-free, and highly reliable has become more and more popular in the industry. This article mainly introduces what is an inflatable switchgear, and what are its characteristics and advantages.

The gis gas insulated switchgear is to fill the compressed gas (SF6 or mixed environmental protection gas) into the air box with a certain pressure. These gases play a role of complete insulation in the inflatable switchgear, and due to the compact structure, the inflatable switchgear has Conducive to the development of miniaturization. This switchgear has the following characteristics:

1. Adopt maintenance-free vacuum circuit breaker technology to reduce or even avoid maintenance;

2. The isolating switch and the grounding device switch form a three-position switch, which replaces the separate switch, greatly reducing the space and interlocking tasks;

3. The current transformer uses the ring core current transformer to replace the ordinary cast insulation current transformer with high charge;

4. Select SF6 gas with excellent insulation performance as the insulating medium to achieve full insulation and full closure, which can prevent the influence of flood and pollution on the stability of the switchgear;

5. No maintenance is required, and the cable inlet and outlet are fully insulated. In addition, it has a live display function, which can accurately display the live status of each circuit;

6. A variety of wiring schemes, which can match a variety of best combination schemes according to the actual project requirements, so as to meet the needs of various incoming and outgoing line circuits;

7. Modular design, which can be expanded according to demand. The same air box can realize up to 5 modules. When there are more than 5 modules, it can be realized by busbar expansion, and the expanded busbar is also fully insulated and fully shielded.

The above is a brief description of the characteristics of the gis gas insulated switchgear. For more detailed information about this product, you can consult or consult our official website.
