MRHBXGN-12(F) Environment-friendly gas insulated metal enclosed switchgear

Summary
MRHBXGN-12(F) environment-friendly gas insulated ring network cabinet is a distribution switchgear that uses vacuum arc extinguishing chamber to extinguish the arc. The environment-friendly gas is the main insulating medium, a small amount of solid insulation supports, and the main circuit is free of any encapsulation. In normal operation, it is zero gauge pressure or micro positive pressure (the air pressure of the gas box is ≤0.02MPa), and the relative and interphase insulation capacity meets the air insulation requirements under zero gauge pressure.
The environment-friendly gas insulated metal enclosed switchgear is the most commonly used three-phase AC intelligent environment-friendly gas insulated switchgear, and is widely used in various complete sets of switchgear. With the concentration of the domestic population, the power market must be matched, and the environment-friendly gas insulated switchgear will also be more and more in demand with the development of the market; The market potential remains to be developed. At the same time, as the product integrates multiple functions such as data acquisition and control, data processing and storage, online monitoring of switchgear and advanced analysis, it carries out online intelligent monitoring and management of the distribution network, enabling the distribution network to operate in a safe, reliable, high-quality and efficient optimal state, realizing remote monitoring, control and management of the distribution network of the power system, and realizing power grid optimization, power safety, power management Demand for energy conservation and consumption reduction; The system can also be widely used in transportation, factories, hospitals, schools, buildings, residential areas, commercial office buildings and other intelligent power distribution fields.
