BPG(H)-40.5kV environmentally friendly gas insulated and metal-enclosed switchgear (C-GIS) uses dry air as the main insulating medium. 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 widely used in urban power grid transformation, distribution stations, load center power stations, petrochemical industry, steel industry and mining industry.
Features
●Green and environmentally friendly: Dry air 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. The inner cone cable plug-in technology is adopted, so that cables, lightning arresters and PTs can be connected by plug-in, with stronger insulation capacity. The gas box is designed with two gas chambers. A separate gas chamber for the three-position switch and busbar, and a separate gas chamber for the circuit breaker switch.
●Compact structure: Mini design, compact structure, small size and small footprint. It can greatly save limited urban land.
●Simple installation: This product has the characteristics of modular design, flexible combination and easy to operation. The sides of the cabinets are connected by parallel bus connectors, which is easy to install. The voltage transformer and lightning arrester are plug-in and installed outside the gas box, which is easy for installation and replacement.
●Intelligent configuration: Intelligent control system, self-power supply protection system and panoramic intelligent power distribution platform are optional to meet the distribution network automation requirements.
●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.
