Overview

Air-12 Environmentally-Friendly Gas-Insulated Metal-Enclosed Switchgear utilizes a vacuum arc-extinguishing chamber, with environmentally friendly gas as the primary insulating medium and a small amount of solid insulating supports. The main circuit has no encapsulation, maintaining a zero gauge pressure or slight positive pressure during normal operation (the gas pressure in the tank≤0 .02 MPa). Moreover, the insulation capability between phases and relative to ground meets the air insulation requirements for distribution switchgear under zero gauge pressure.
This environmentally friendly gas-insulated metal-enclosed switchgear is one of the most commonly used three-phase AC intelligent eco-friendly gas-insulated cabinets, widely applied in various complete switchgear systems. As the population concentrates domestically, the power market requires matching support, and the demand for environmentally friendly gas-insulated switchgear will continue to grow with market development; the market potential remains to be explored.
Additionally, the product integrates functions such as data collection and control, data processing and storage, online monitoring of switchgear, and advanced analysis, facilitating intelligent online monitoring and management of the distribution network. This ensures that the distribution network operates in a safe, reliable, high-quality, and efficient state, achieving remote monitoring, control, and management of the power system 's distribution network. It meets the demands for grid optimization, electrical safety, energy management, and energy conservation. The system can also be widely applied in intelligent distribution fields such as transportation, factories, hospitals, schools, buildings, residential communities, and commercial office buildings.
