What are the main features of inflatable switchgear?
With the development of the economy and society, the use of gas-insulated switchgear is increasing. In recent years, compact, environmentally friendly, maintenance-free, and highly reliable gas-insulated switchgear has become increasingly favored in the industry. This article mainly introduces what gas-insulated switchgear is, as well as its characteristics and advantages.
Gas-insulated switchgear is a type of switchgear that fills a gas chamber with compressed gas (SF6 or a mixture of environmentally friendly gases) at a certain pressure. These gases provide complete insulation in the gas-insulated switchgear, and due to its compact structure, it is conducive to miniaturization. Specifically, this type of switchgear has the following characteristics:
1. Uses maintenance-free vacuum circuit breaker technology, reducing or even avoiding maintenance situations;
2. The isolating switch and grounding device switch form a three-position switch, replacing individual switches, greatly reducing space and interlocking tasks;
3. Current transformers use ring-core current transformers instead of ordinary cast resin insulated current transformers that bear high charges;
4. Selects SF6 gas with excellent insulation properties as the insulating medium, achieving full insulation and full sealing, which can prevent the impact of floods and dirt on the stability of the switchgear;
5. No maintenance is required, and the cable entry and exit are fully insulated. In addition, it has a live display function that can accurately show the live status of each circuit;
6. Multiple wiring schemes can be matched according to actual project needs to meet the requirements of various incoming and outgoing circuits;
7. Modular design allows for expansion according to needs. The same gas chamber can accommodate up to 5 modules, and when there are more than 5, it can be expanded through busbars, which are also fully insulated and fully shielded.
The above is a brief description of the characteristics of gas-insulated switchgear. For more detailed information about this product, you can refer to or consult our company's official website.
