The CDRM6 series GIS is new generated small size modular switch equipment have modular structure, such as the unit type and box type. Each module has its own functions and metal enclosure, and they can extend at the right and left side arbitrarily. According to different design scheme, they can combine arbitrarily to complete different distribution work. When the number of the configuration modules is more than 6 modules, the switchgear should be connected through extending busbar, which achieve semi modularized structure. All gas tanks are adopted 3mm imported stainless steel sheets, which is welded automatically by automatic rotary platform and Japanese Panasonic welding machine to ensure the leak proofness of the tank. The tank is filled with SF6 gas, and the load switch, earthing switch etc. switch moving parts and the busbar are sealed in the stainless steel tank, which greatly improve the safety performance electric products and the IP of GIS enclosure is reached to 67. The bottom of the tank is installed with explosion-proof membrane. It can prevent people from the injury effectively, also no damage occurs in cable, switch station and other switch equipment.
The 24kV switchgear is the top GIS ring main unit. The material and manufacture process are under strict control. The necessary materials such as main epoxy components, plastic parts and silicone rubber components are supplied from famous international company. All of the materials must be test by helium mass spectrometer leak detector and X-ray nondestructive flaw detector, as well as relative partial discharge test and voltage test, to ensure all the components are reliable. During the assembling process, mechanical characteristic test instrument imported from Germany is employed to accurately test the electric & mechanical performance, for example, breaking-closing switch period, stroke and speed, thus to guarantee the producing quality of the production. With the advantages of the compact structure, whole sealing, fully insulation, long life, free maintenance, small size and safety, CDRM6 series GIS is widely used in industrial and civil cable ring net and power supply terminal, and it is suitable for small-size secondary power distribution station, switching station .industrial and mining enterprises, airport, railway, commercial district, buildings, high ways and the places of severe environment.
The metal enclosed switchgear uses SF6 gas as arc-extinguishing and insulating medium. It adopots fully-sealed and fully- insulating structure. Busbar, switches and live parts are completely sealed in stainless-steel case, which is filled with SF6 gas of 1.4 bar pressure. Its protection rating can reach IP67. The whole switch decive is protected from external environment. Even under extreme case like immersed in water for short time, it can operate normally. This product is maintenance free for life long. This series GIS are provided with five interlocking decives for safeguard to keep the operators and equipments from breakdown which is caused by manual misoperation. All switchgears have reliable pressure relief decives, which guarantees the safety of operators under extreme conditions. Switchgears can be classified as fixed unit combination and extensible unit combination. The incoming and outgoing lines are installed at the front. Line installation at sides are also available. The switchgear is of small size, which makes mounting easy. It can be installed in places of small space and bad environment. Automatic, remote-controlling, monitoring decives can be installed according to customized requests
The switch cabinet is kept from the influence of bad environment, such as condensation, rime, salt mist, etc. All HV live parts and switch components are fully sealed in SF6 gas case. It is with features of compact structure, small size, light weight, completely insulation. Modularization and module combination can make different combination of main wiring. The circuit adopts silicone rubber connectors to make HV components connection and switchgear extension possible. It can be combined with HV monitor unit, integrated digital circuit breakers and overcurrent protective relay. The switchgear is provied with waterproof feature and long lifespan. Maintenance free will reduce operation cost, which meet the requests of distribution network automated upgrade.
