Abstract
The utility model discloses a separating position-limiting structure of an outdoor high-voltage alternating current vacuum circuit breaker. A rubber gasket of a separating position-limiting part (1) of the separating position-limiting structure and a metal gasket are obliquely and alternately superposed, the impact surface of the separating position-limiting part (1) is a slope, and the impact surface of a main driving rod (2) of the circuit breaker is also the slope and is parallel to the slope of the separating position-limiting part (1). The separating position-limiting structure can effectively control the separating rebound of the circuit breaker and improve the mechanical life and the electrical performance of the circuit breaker.
Description
Technical field
The utility model relates to a kind of outdoor high-voltage alternating current vacuum circuit-breaker separating brake position limiting structure in the electrical power distribution system.
Background technology
Along with the continuous development of power industry and power technology, China's power transmission and distribution performance of products has all had good raising, for the fail safe and the reliability of electrical network provides certain guarantee.But along with national grid to the quality of electric energy and improving constantly of power transmission and distribution reliability requirement, the structure of some products still needs further innovation, improves.The separating brake stopping means of present 12kV outdoor high-voltage alternating current vacuum circuit-breaker; Its structure is as shown in Figure 1; Mainly form by separating brake locating part 1 (adopt and constitute) and circuit breaker main transmission bar 2 by the alternate stack of rubber gasket with metallic gasket, the vertical alternate stack of separating brake locating part 1 rubber gasket and metallic gasket, the striking face of separating brake locating part 1 and main transmission bar 2 is a perpendicular; Circuit breaker main transmission bar 2 vertically impinges upon on the separating brake locating part 1 under the drive of tripping spring 3 during separating brake.The separating brake rebound phenomena is in the position limiting structure existence of this vertical bump; Promptly positive vertical bump makes the circuit breaker main transmission bar 2 very big distance of rebounding; Impinge upon on the separating brake locating part 1 falling after rise once more under the drive of tripping spring 3 then, to clash into final circuit breaker main transmission bar 2 repeatedly and be pressed on the separating brake locating part 1.The separating brake bounce-back not only reduces the mechanical endurance of circuit breaker, and influences the electric property of circuit breaker.
Summary of the invention
The purpose of the utility model provides a kind of outdoor high-voltage alternating current vacuum circuit-breaker separating brake position limiting structure that can eliminate the separating brake rebound phenomena.
The technical scheme of the utility model is: a kind of outdoor high-voltage alternating current vacuum circuit-breaker separating brake position limiting structure, form by separating brake locating part, circuit breaker main transmission bar, tripping spring and circuit breaker frame.Rubber gasket and the metallic gasket that the is characterised in that the separating brake locating part alternate stack of tilting, the striking face of separating brake locating part is the inclined-plane, the striking face of circuit breaker main transmission bar also is the inclined-plane, and parallel with the inclined-plane of separating brake locating part.
The separating brake position limiting structure of the outdoor high-voltage alternating current vacuum circuit-breaker that the utility model provides; Make the original perpendicular of separating brake locating part become an inclined-plane; The face that contacts with the separating brake locating part during circuit breaker main transmission bar separating brake also becomes an inclined-plane by original perpendicular; The impact of the two changes over the inclined-plane oblique impact by original vertical bump during separating brake; The component that rebounds on the opposite direction that receives when making the motion of main transmission bar separating brake reduces, and is limited in the final position by the separating brake locating part, no longer bounce-back.Effectively suppress the separating brake bounce-back, improved the mechanical endurance and the electric property of circuit breaker.
Description of drawings
Fig. 1 is the sectional structure sketch map of existing outdoor high-voltage alternating current vacuum circuit-breaker separating brake position limiting structure;
Fig. 2 is the sectional structure sketch map of an embodiment of the utility model outdoor high-voltage alternating current vacuum circuit-breaker separating brake position limiting structure.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: 1, separating brake locating part 2, main transmission bar 3, tripping spring 4, circuit breaker frame
As shown in Figure 2, the utility model outdoor high-voltage alternating current vacuum circuit-breaker separating brake position limiting structure is made up of separating brake locating part 1, circuit breaker main transmission bar 2, tripping spring 3 and circuit breaker frame 4.Rubber gasket and the metallic gasket that the is characterised in that separating brake locating part 1 alternate stack of tilting, the striking face of separating brake locating part 1 is the inclined-plane, the striking face of circuit breaker main transmission bar 2 also is the inclined-plane, and parallel with the inclined-plane of separating brake locating part 1.
During separating brake; To left movement, its inclined-plane impinges upon on the inclined plane of separating brake locating part 1 circuit breaker main transmission bar 2 under the pulling of tripping spring 3, because the interaction force between the object is perpendicular to acting surface; So the active force during the separating brake bump is perpendicular to the inclined-plane of the two; And the component on circuit breaker main transmission bar 2 directions of motion just becomes very little, just makes the power of circuit breaker main transmission bar 2 bounce-backs very little, so under the pulling of tripping spring 3; Circuit breaker main transmission bar 2 just no longer produces the separating brake bounce-back, is limited in the separating brake position reliably.
The utility model outdoor high-voltage alternating current vacuum circuit-breaker separating brake position limiting structure has effectively been controlled the separating brake bounce-back of circuit breaker, has improved the mechanical endurance and the electric property of circuit breaker.
