Environment-Friendly Gas-Insulated Ring Network Switchgear
The HBXGN-40.5 environment-friendly gas-insulated ring network switchgear employs a vacuum arc-extinguishing chamberutilizes eco-friendly gas as the primary insulation medium with minor solid insulation supports, and features no encapsulation in themain circuit. lt operates at zero gauge pressure or slightly positive pressure (with the gas tank's air pressure not exceeding0.02MPa) during normal conditions, and its insulation capablities relative to ground and between phases satisfy the air insulationrequirements at zero gauge pressure.This environment-friendly gas-insulated ring network switchgear is a frequently employed three-phase Ac inteligent cabinetextensively utilized in various switchgear assemblies. As the population becomes more concentrated domestically, the powermarket must adapt accordingly, necessitating a growing demand for eco-fiendly gas-insulated switchgear alongside marketdevelopment; The market's potential remains untapped. Additionally, with features that integrate data acquisition and control, dataprocessing and storage, and online monitoring and advanced analysis of switchgear, this product inteligently conducts onlinemonitoring and management of distribution networks, ensuring they operate in a safe,reliable, high-quality, and efficient mannerIt facilitates remote monitoring, control, and management of power system distribution networks, fulfling the requirements fopower grid optimization, electrical safety, energy management, and the reduction of energy consumption and waste. Furthermorethe system is broadly applicable in inteligent power distribution sectors, including transportation, factories, hospitals, schoolsbuildings,residential complexes, and commercial office buildings
