Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Inflated type breaker cabinet of the present invention, it includes gas tank (1), first goes out kind of thread elements, second goes out kind of thread elements, and it is sealed in the chopper in gas tank (1), tri-station isolating switch and a high voltage device, and it is located at gas tank (1) circuit breaker operation mechanism (2) outward, Three-Position Switch Operate Institutions (3), the first of every phase goes out kind of thread elements, second goes out kind of thread elements all includes being located at gas tank (1) air insulation sleeve pipe (4) outward, one end of the electrical connections of each air insulation sleeve pipe (4) sealed connection enters in gas tank (1), its other end is at gas tank (1) outward.
Owing to circuit theory does not change, so one end of the electrical connections of air insulation sleeve pipe (4) electrically connects employing prior art with the respective element in gas tank 1, it is not added with repeating.
Air insulation sleeve pipe (4) is six, triplet, amounts to two groups, is under the jurisdiction of first respectively and goes out kind of thread elements and second and go out kind of thread elements, one of which is positioned at gas tank (1) left plate top, and another group is positioned at gas tank (1) right plate top.
The air insulation sleeve pipe (4) often organized is in the horizontal plane in sector distribution, and the symmetrical distribution of two groups of air insulation sleeve pipes (4).
Gas tank 1 is the air-tightness casing being welded by corrosion resistant plate, inside fills a kind of dielectric.
Chopper includes vacuum interrupter 7, support 8 and driving-chain 5 thereof, and vacuum interrupter 7 is fixed on support 8, is longitudinally arranged before in after described vacuum interrupter 7, and driving-chain 5 is responsible for being delivered to the kinetic energy of circuit breaker operation mechanism 2 moving contact of vacuum interrupter 7; Driving-chain 5 includes the first insulated tension pole 10, drives connecting rod the 6, first main shaft 11, first main shaft 11 is connected with the first output shaft 17 by the first seal disc 16, accept the output work of circuit breaker operation mechanism 2, then the first insulated tension pole 10 is driven, quick acting through connecting rod 6 of overdriving, it is achieved the conjunction of the moving contact of vacuum interrupter 7 divides.
Tri-station isolating switch is positioned at the lower section of chopper, is integrated design with chopper, makes compact equipment, effectively reduces the whole height of cabinet, and it includes contact the 15, second insulated tension pole the 14, second main shaft 12; Second main shaft 12 is connected by outside second output shaft 19 of the second seal disc 18 and gas tank 1, accepts the output work of Three-Position Switch Operate Institutions 3, then drives the second insulated tension pole 14, it is achieved the action of contact 15.
Distribution before in after described chopper and tri-station isolating switch A, B, C three-phase work.
Being enclosed in the uniformity considering electric field when in gas tank 1 high voltage device busbar 13 designs, special handling is all done on its junction and surface.
Element outside gas tank 1 mainly includes circuit breaker operation mechanism 2, Three-Position Switch Operate Institutions 3, air insulation sleeve pipe 4 etc.
