Development of the New 24kV Cubicle Type Gas-Insulated Switchgear (C-GIS) Series for Overseas Markets Toyohisa Tsuruta, Mitsuaki Serizawa Keywords Switchgear, Downsizing, Low power loss, Insulated busbars, No Gas Handling work, Standardization Abstract A switchgear is a major apparatus that establishes a substation facility. The

When introducing a new technology, lack of long-term experience can cause reluctance among potential users. This holds true especially for industries where products are expected to work reliably for 30 years or more, as is the case for gas-insulated switchgear. The SF6 gas insulated substation (GIS) is assembled by several SF6 gas insulated

install an online density system on gas insulated switchgear (GIS) substation were current monitoring in manual checking of gauges and a new GIS Substation where there is a stand alone online density system installed through construction, and then evaluate the benefit case for running a scheme to roll out to other substations.

The interrupter of circuit breaker is designed as double-break structure, and the hydraulic operating mechanism avoids the oil leak and slow-opening at zero pressure. With rated current of 5000A and rated short-circuit breaking current of 50kA, this kind of GIS have been adopted in Substation GuanTing of 750kV power transmission project in Northwest China.

Most recently, the utility purchased a second dry-air/vacuum GIS for a 115-kV, 50-kA, 3000-A multi-bay GIS at its new Hunters Point substation. Get Price

Strategy for Elimination of SF6 in Production Processes. Transfer emissions due to residual level of SF6 left in tank and later released to atmosphere Contamination (errors, accidents or from the partial evacuation of air before filling with SF6) eventually results in need to replace “shop” SF6 Large leaks due to defects in parts or assembly or accidents (such as premature rupture disk

Jan 01, 2011A Strong and Smart Grid is the development direction and established target of future grid in China. In respect that Smart Substation is the principal foundation and support of Smart Grid, the research on key technologies about Smart substations has attracted an increasing amount of attention in the recent years.

Solutions Energy The VISION Group hybrid solution combines the advantages of GIS (gas insulated substation SF6) with the simplicity of the air-insulated substation, and can be found at voltage levels of 145 kV to 550 kV. This is the most reliable and cost-effective solution for new installations, expansions or replacement of existing substations.

Hybrid – GIS (HGIS) is a new type of high-voltage switchgear which is compact in size, reliable in operation and economical in cost. HGIS is mainly composed of Bushings (BSG), Disconnecting Switch (DS), Earthing Switch (ES), Circuit Breaker (CB), and Current Transformer (CT), etc.

Compared with outdoor air-insulated substations, gas-insulated metal-enclosed substations, ie GIS substations, have high reliability and long service life, but their investment cost is high. A new type of substation, a modern compact substation, being researched and developed combines the advantages of these two substations.
