Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker.
Background technology
Domestic installed capacity is 600,000 kilowatts and above large electric power plant, water power power plant project, and relatively high to the requirement of indoor high-voltage vacuum circuit breaker, wherein short circuit interruption capacity is 50kA, and Dynamic stability coefficient is 3 times, reaches 150kA.But the vacuum circuit-breaker short circuit interruption capacity that Present Domestic is produced is mostly at below 40kA, Dynamic stability coefficient is 2.5 times, cannot meet user's requirement.And the producer of the domestic production of this series products is at present little, be almost in vacuum state.
Summary of the invention
The purpose of this utility model is just to provide a kind of novel height and cut-offs indoor high-voltage vacuum circuit breaker, and its technical scheme taked is:
Comprise chassis vehicle, cabinet, pole, moving contact and contact arm, chassis vehicle is by quiet support, dynamic support and four rolling composition, wherein quiet support is connected by screw mandrel with dynamic support, each roller is located at the bottom of dynamic support, the leading flank of quiet support is provided with two handles, the left and right side of quiet support is respectively equipped with hyoplastron, cabinet is fixed on dynamic support, spring mechanism and switching-in spring is provided with in cabinet, the left and right sides wall at cabinet rear portion is respectively equipped with valve pressing plate, the left side on cabinet top, right side and front side are respectively equipped with left shrouding, right shrouding and middle shrouding, cabinet bottom cover plate, the front end of contact arm is fixedly connected with moving contact by garter spring, the rear end of contact arm is bolted on the leading-out terminal of pole.
This circuit breaker is exclusively used in domestic installed capacity 600,000 kilowatts and above large electric power plant, water power power plant project, and have compact conformation, volume is little, the advantages such as height cut-offs, dependable performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As depicted in figs. 1 and 2, chassis vehicle is by quiet support 1, dynamic support 3 and four rolling 2 form, wherein quiet support 1 is connected by screw mandrel 16 with dynamic support 3, each roller 2 is located at the bottom of dynamic support 3, ensure that circuit breaker cart shakes into smoothly movement when shaking out cabinet, the leading flank of quiet support 1 is provided with two handles 10, the left and right side of quiet support 1 is respectively equipped with hyoplastron 9, hyoplastron 9 and cabinet lock, ensure that quiet support 1 locks with cabinet, now shake screw mandrel 16 clockwise, dynamic support 3 drives circuit breaker cart to advance, enter into cabinet service position, otherwise then retreat to cabinet test position.
Cabinet 5 is fixed on dynamic support 3, spring mechanism 4 and switching-in spring 11 is provided with in cabinet 5, the left and right sides wall at cabinet 5 rear portion is respectively equipped with valve pressing plate 17, the left side on cabinet 5 top, right side and front side are respectively equipped with left shrouding 15, right shrouding 13 and middle shrouding 14, playing circuit breaker shakes after cabinet, improve the effect of degree of protection
Cabinet 5 bottom cover plate 12, improves the degree of protection of complete machine.
The front end of contact arm 7 is fixedly connected with moving contact 8 by garter spring, moving contact 8 is by increasing the enclasping force of contact quantity and raising contact garter spring, reach the requirement of height dynamic and thermal stability when dynamic and static contact engages, the rear end of contact arm 7 is bolted on the leading-out terminal of pole 6, in pole 6, dynamic/static contact is by special process process, and back is strengthened by reinforcement, improves intensity, and coordinate spring mechanism 4 and switching-in spring 11, meet the high rigors cut-off of circuit breaker.
