Abstract
The utility model discloses a nuclear power indoor high-voltage vacuum circuit breaker. A chassis of the circuit breaker comprises a fixed bracket of a chassis truck and a movable bracket of the chassis truck which are connected by guide screws; the front end of the movable bracket of the chassis truck is provided with a limiting pin; a mechanism box is fixed on the movable bracket of the chassistruck; valve pressing plates are respectively arranged at the left side and the right side of the mechanism box; a spring mechanism is arranged on the mechanism box; the back part of a sealed polar pole is fixedly connected with the mechanism box, and the front part thereof is fixedly connected with a movable contact arm; and the front end of the movable contact arm is connected with a movable contact. The circuit breaker has the advantages of small volume, high opening and closing and reliable performance.
Description
Technical field
The utility model relates to a kind of indoor high-voltage vacuum circuit breaker.
Background technology
Present domestic high-pressure vacuum breaker structural design can not satisfy certain shockproof requirements; The design service life of product is shorter, is generally about 10 years; The vacuum circuit breaker volume of constructed parameter is bigger; Connecting-disconnecting function and making capability can not satisfy the requirement of mega kilowatt nuclear power generators.Based on above reason, domestic existing indoor high-voltage vacuum circuit breaker can not be directly used in the nuclear island of nuclear power station control system.
Summary of the invention
In order to solve problems of the prior art, the utility model provides a kind of nuclear power indoor high-voltage vacuum circuit breaker, and its technical scheme of taking is:
This isolating switch comprises isolating switch chassis, valve pressing plate, mechanism case, pole, acting arm, moving contact and spring device, the isolating switch chassis comprises quiet support of chassis and the moving support of chassis, they connect by leading screw, the moving support front end of chassis is established spacer pin, mechanism case is fixed on the moving support of chassis, the valve pressing plate is located at the mechanism case left and right sides respectively, spring device is located on the mechanism case, fixedly connected with mechanism case in the pole back, fixedly connected with acting arm in its front portion, the acting arm front end connects moving contact.
This isolating switch also comprises right protective shield, protective shield, left protective shield and panel, and right protective shield, protective shield and left protective shield are separately fixed at left side, front side and the right side at mechanism case, and panel covers mechanism case.
This isolating switch chassis motor-car frame Front-end Design prelocalization pin cooperates with the spacing bent plate of cabinet, thereby realizes the front limit of handcart working position, plays the purpose of spacing antidetonation; Optimize the tolerance clearance between the right protective shield of isolating switch, protective shield, left protective shield and cabinet, it is spacing to strengthen handcart during shock test.The pole insulating material adopts ageing-resistant epoxy resin, prolongs service life of equipment, effectively dwindles the volume of vacuum circuit breaker.By increasing number of contacts and improving contact and hold power tightly, make dynamic and static contact satisfy high dynamic and thermal stability requirement.Pole back fixation point adds reinforcement, improves the constant intensity at pole middle part, and whole pole tension and the bending strength of improving is to satisfy the requirement that height cut-offs Gao Guanhe.
This isolating switch has that volume is little, height cut-offs, the advantage of Gao Guanhe, dependable performance, and product is the supporting use of nuclear safe level Medium Voltage Switchgear, is the emergent station-service power devices in the nuclear island factory building.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As depicted in figs. 1 and 2, the quiet support 1 of chassis links to each other by the moving support 3 of leading screw 16 and chassis, forms the isolating switch chassis, and 4 rollers 2 are established in its bottom, guarantees that handcart smoothly moves when shaking into; Operating grip 17 when isolating switch cooperated with cabinet, and dead bolt 18 can lock with cabinet, guaranteed quiet support 1 of chassis and cabinet locking, shook leading screw 16 clockwise, and the moving support 2 of chassis moves forward, otherwise then retreats.
Spring device 15 is installed on the mechanism case 5, mechanism case 5 is fixed on the moving support 3 of chassis, valve pressing plate 4 is located at the mechanism case left and right sides respectively, right protective shield 9, protective shield 10, left protective shield 11 are fixed on left side, front side and the right side of mechanism case 5 respectively by bolt, play the effect that protection improves degree of protection.Moving contact 8 connects acting arm 7 front ends by the power of holding tightly of bundle spring, the back of pole 6 is fastening by high-strength bolt and mechanism case 5, to improve the stability of pole, its front portion reliably is connected with acting arm 7 by bolt, panel 12 covers mechanism case 5, establishes manual brake separating button 13 and closing by hand button 14 on the panel 12; Circuit breaker cart is behind the working position, and the spacer pin 19 that is contained in moving support 2 front ends of chassis cooperates with the spacing bent plate of cabinet, plays the purpose of spacing antidetonation.
