Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is a kind of overall structure schematic diagram of horizontal vacuum circuit breaker for high-voltage alternating current generator, has arrangements of electric connection of the present utility model outside the arc control device moved end of this vacuum circuit-breaker;
Fig. 2 is the structural representation of single-phase on-off system among Fig. 1.
Embodiment
With reference to Fig. 1, a kind of high-voltage alternating current generator vacuum circuit-breaker mainly comprises steelframe 1, is fixed on the triphase horizontal on-off system 2 on the steelframe 1.
With reference to Fig. 2, in every mutually horizontal on-off system 2, fixing three moved end post insulators 3, two quiet end pillar insulation 4 on steelframe 1, five post insulator yi word patterns are arranged, moved end aluminum frame 5 is fixed on three moved end post insulator 3 tops, quiet end aluminum frame 6 is fixed on two quiet end post insulator 4 tops, is provided with vacuum interrupter 7 between moved end aluminum frame 5 and the quiet end aluminum frame 6.
Vacuum interrupter 7 comprises moved end and quiet end, and quiet end aluminum frame 6 is fixedlyed connected with the quiet end of vacuum interrupter 7, and realizes being electrically connected.The moved end of vacuum interrupter 7 is electrically connected with moved end aluminum frame 5 by spring touch finger 8, is specially: the moved end of vacuum interrupter 7 comprises moving bar 701, is arranged on the moving contact (the not shown in the figures meaning out) of moving bar 701 right-hand members, the sliding contact 702 that is arranged on moving bar 701 left ends and the push rod 703 that is fixed on sliding contact 702 left ends; The cross section of moved end aluminum frame 5 is the rectangle of hollow, and push rod 703 and sliding contact 702 stretch in the aluminum frame of moved end; The right-hand member of moved end aluminum frame 5 is provided with spring touch finger 8, and push rod 703 and sliding contact about 702 run through spring touch finger 8, and spring touch finger 8 electrically contacts with sliding contact 702.Simultaneously, for the moving contact that guarantees vacuum circuit-breaker and the contact pressure of fixed contact, push rod 702 is provided with and is used to measure the dish spring 704 that push rod keep-ups pressure, can directly calculate the contact pressure of moving contact and fixed contact by the compression degree of dish spring 704, as one of foundation of judging the circuit breaker reliably working.
The cross section of moved end aluminum frame 5 and quiet end aluminum frame 6 is for being the rectangle of hollow, and is convenient fixing; Especially the space of the hollow of moved end aluminum frame 5 provides actuating length for the moved end of vacuum interrupter 7, the actuator of the moved end that is used for vacuum interrupter 7 is installed simultaneously, the bottom surface of moved end aluminum frame 5 is offered through hole, the extended moved end of the input of actuator aluminum frame 5.
Described in conjunction with the accompanying drawings above specific embodiment of the utility model only is schematic; rather than as restriction to claims content of the present utility model and scope; every foundation technical spirit of the present utility model still belongs to technology of the present utility model and rights protection category to any simple modification, modification and equivalent variations (changing vertical structure into by horizontal type structure as arc control device) that above embodiment did.
