Is the GIS in the electric power high voltage switch cabinet
IS is a shorthand for two conceptsThe 1 is the geographic information system.2 refers to the (GAS INSULATED SWITCHGEAR) gas insulated fully enclosed combination of electrical appliances, closed inside the main circuit breaker, isolation switch, grounding switch, bus, lightning arrester, etc.. Many power plants, substations, switching stations are made of GIS, so that the small footprint, or maintenance. With the high voltage switch cabinet or not.

High voltage electrical (mainly above 35kV) exposed to the air, common substation circuit breaker, isolating switch, bus, phases, equipment, and equipment between between and so must have a relatively large safety distance. This area is relatively large, but also exposed to the outside of the security risks are more. GIS is a kind of technology, the bus CircuitBreakers isolating switch for high-voltage electric appliances shell pack, seal filled with six sulfur hexafluoride gas, according to the elements of seal, not a whole big box, such as every bus from the outside is a large cylinder etc.. This equipment can be very compact layout, and a sealed shell, but also more secure.High voltage switchgear is only a device installed in a cabinet, and this is generally high voltage 10kV, up to 35kV, and then there is no general high switch cabinet this form. Of course, you can also use GIS technology. But generally speaking, GIS is more than 110kV GIS switch station.You can Baidu image search GIS switch station". You can see that the big cylinder together is the GIS switch equipment, large cylinder which is the bus, circuit breakers and other equipment, see pictures more intuitive.
