Abstract
The utility model discloses a double-acting explosion chamber transmission structure. The double-acting explosion chamber transmission structure comprises two pull rods, two reverse direction pull rods and two commutation handles, wherein one end of the two pull rods and one end of the two reverse direction pull rods are respectively in movable connection with two ends of the two commutation handles. According to a technical scheme, a core portion of the double-acting explosion chamber transmission structure is formed. The double-acting explosion chamber transmission structure realizes double acting of a breaker explosion chamber, enables output power of a mechanism to be reduced to be 40% of single acting, completely realizes a breaker matched with a domestic spring mechanism with small power, improves mechanical service life of the breaker and reduces cost.
Description
Technical field
The utility model relates to a kind of drive mechanism, especially relates to a kind of two moving arc control device drive mechanism of the metal-enclosed combined electric circuit breaker for high-tension electricity.
Background technology
On the market, be used for the metal-enclosed combined electric switch of high-tension electricity now, the transmission of its arc control device is one-sided motion, and namely arc control device are divided into fixed contact and moving contact; During separating brake, mechanism drives the moving contact motion; For successful arc extinguishing, moving contact must reach V=9m/s for the relative velocity of fixed contact, because fixed contact speed is 0m/s, so the speed of moving contact must reach V=9m/s, the output speed of corresponding mechanism also should be V=9m/s, and output work is
For general circuit breaker, its operating work will arrive about 3000J, so mechanical endurance is lower, and owing to general spring mechanism power output does not reach, so most of producer selects imported hydraulic mechanism, so that whole product cost is high.
Summary of the invention
In order to solve in the market owing to the metal-enclosed combined electric switch breaker operator life-span in the high-tension electricity is low, serious dependence on import hydraulic mechanism and the high in cost of production that causes is not enough, the applicant has improved and has invented the drive mechanism of the two moving arc control device of a kind of metal-enclosed combined electric switch circuit breaker through further investigation; It has simple in structure, high reliability.
A kind of two moving arc control device drive mechanisms of the present utility model, its technical scheme is: comprise two pull bars, two reverse pull bars, two commutation handles; One end of described two pull bars, two reverse pull bars is flexibly connected with described two commutation handle two ends respectively.
Wherein, also comprise arc control device, described arc control device are divided into the master end of arc control device and the passive side of arc control device;
Wherein, the master end of the other end of described pull bar and described arc control device is flexibly connected;
Wherein, the passive side of the other end of described reverse pull bar and described arc control device is flexibly connected;
Wherein, the center of described commutation handle is provided with fixing central point, and described commutation handle can rotate around fixing central point.
By technique scheme, can consist of the core of the two moving arc control device drive mechanisms of a kind of metal-enclosed combined electric switch circuit breaker of the utility model.The utility model of consisting of of technical scheme thus, its beneficial effect is: realized that fully arc-extinguishing chamber of circuit breaker is two moving, so that the output work of mechanism is decreased to 40% of single action greatly, can realize that fully circuit breaker joins low power domestic spring mechanism, increase the mechanical endurance of circuit breaker, reduced cost.

Embodiment
Below in conjunction with accompanying drawing a kind of two moving arc control device drive mechanism operating states of the utility model are described in detail:
A kind of two moving arc control device drive mechanisms of the present utility model are mainly used in the metal-enclosed combined electric switch circuit breaker; See also Fig. 1, Fig. 5, Fig. 6; Wherein, an end of pull bar 1 links to each other with the end points 5 of commutation handle 3; Oppositely an end of pull bar 2 and another end points 6 of described commutation handle 3 link to each other.The other end of described pull bar 1 and the master end of arc control device 7 are flexibly connected; The passive side 8 of the other end of described reverse pull bar 2 and arc control device is flexibly connected; Described commutation handle 3 can rotate around fixing central point 4; During combined floodgate, mechanism drives pull bar 1 toward moving right by the master end 7 of described arc control device, so that commutation handle 3 drives reverse pull bar 2 toward left movement clockwise along central point 4 rotations, drives the passive side 8 of arc control device toward left movement, and combined floodgate work is finished; During separating brake, the master end 7 of mechanism by described arc control device drives pull bars 1 toward moving left, so that commutation handle 3, drives the motion of turning right of reverse pull bar 2 counterclockwise along central point 4 rotations, and the motion of turning right of the passive side 8 of drive arc control device, separating brake work is finished.
Be understandable that, above execution mode only is the illustrative embodiments that adopts for principle of the present utility model is described, yet the utility model is not limited to this; For those skilled in the art; all for reaching the purpose of this utility model; realize function of the present utility model; in the situation that do not break away from the utility model spirit and essence; can make various modification and improvement to each technical characterictics of technical solutions of the utility model and connected mode thereof etc.; these modification and improvement also are considered as content of the present utility model, belong to protection range of the present utility model.
