The GIS is an English abbreviation of a gas insulated totally-enclosed combined electrical apparatus, and is also called as an SF6 totally-enclosed combined electrical apparatus, wherein the GIS comprises a circuit breaker, a disconnecting switch, a grounding switch, a mutual inductor, a lightning arrester, a bus, a connecting piece, an outgoing line terminal and the like, all the equipment or components are enclosed in a metal grounded shell, and SF6 insulating gas with certain pressure is filled in the metal grounded shell.
GIS is characterized by the fact that live high voltage equipment is enclosed in a grounded metal enclosure and isolated by a high dielectric strength gas medium such as SF 6. However, once a high-voltage device is defective during operation or needs to be repaired due to other reasons, the temporary grounding wire cannot be hung in a power failure manner for maintenance as in a general open-type device. GIS therefore requires the design of relatively many more grounding blades and associated latching functions, both electrical and mechanical, to prevent inadvertent operation. Because circuit breaker, isolator, ground connection isolator all encapsulate in the metal gas room, visual degree is lower, consequently require to adopt the three-phase mechanical linkage isolator that rotates, chain drive mode designed to the alternate connecting rod, should install the divide-shut brake indicator when driven looks the same, but the isolator of current GIS equipment does not set up the divide-shut brake of driven looks and indicates.
