BPG (H)-12kV environmentally friendly gas insulated and metal-enclosed switchgear (C-GIS) uses nitrogen or dry air as the main insulating medium, and uses vacuum switch for opening and closing. The high-voltage components, which are waterproof and dustproof, are not affected by the environment or altitude. It is completely maintenance-free. Permanent magnet or spring operating mechanism and solid-sealed pole vacuum interrupter are adopted to greatly reduce the number of parts. This product is a three-phase AC single-bus, double-bus and bus segmented indoor equipment. It is mainly used in secondary distribution stations, switching stations, public buildings, residential areas, railways and airports. It can operate reliably in harsh environments such as basements, plateaus, frozen soil, and coastal areas with high altitudes, humidity and salt spray. It has a broad application prospect.
Features
●Green and environmentally friendly: Nitrogen (or dry air) gas is used to insulate and seal in the box, without SF₆, toxic and greenhouse gas emissions or impact on the environment.
●Safe and reliable: Five-proof mechanical interlocking system is used to prevent misoperation. All high-voltage components, including cable terminals, lightning arresters, current transformers and voltage transformers, are enclosed in grounded metal casings and are safe to touch.
●Maintenance-free: All primary high-voltage components are sealed in the gas box welded by stainless steel plates with IP67 rating to avoid the influence of external environment on the switchgear. It can reliably operate in harsh environments such as basements, plateaus, frozen soil, coastal areas, and humid areas. It is maintenance-free and has a long service life.
●Compact structure: The switchgear has a compact structure and small size, which can greatly save limited space. The 1250A is only 500mm wide.
●Intelligent: Intelligent control system, self-power supply protection system and panoramic intelligent power distribution platform are optional to meet the distribution network automation requirements.
●Wide environmental adaptability: The gas insulated ring network cabinet uses nitrogen or dry air as the insulating medium. It can be used in low temperature environments without the risk of liquefaction and has wide environmental adaptability.
