Abstract
A vacuum circuit breaker is provided. With the vacuum circuit breaker adopted, the problems of complexity and inconvenient installation of a tripping mechanism of an existing vacuum circuit breaker can be solved. The vacuum circuit breaker includes a mounting frame; the mounting frame is provided with a tripping semi shaft, a buckling plate mounting shaft used for mounting a buckling plate, a first limiting shaft and a second limiting shaft; one end of the buckling plate is snapped to the tripping semi shaft, and the other end of the buckling plate abuts against a rocker arm on a spring operating mechanism; the tripping semi shaft is provided with a plurality of gapped grooves which are recessed inwardly; one end of the buckling plate is arranged at the lower side of one of the gapped grooves; and a limiting plate and a tripping plate are arranged inside the gapped grooves. With the gapped grooves adopted, the limiting plate and the tripping plate can be conveniently installed, and will not occupy the space of a tripping mechanism; and at the same time, the vacuum circuit breaker of the utility model has the advantages of simple structure, convenient installation, reliable tripping, and reliable linkage between the tripping mechanism and an operation mechanism.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker.
Background technology
Along with improving constantly of vacuum circuit-breaker technical merit, vacuum circuit-breaker more and more is widely used in electric power system as the switching device of controlling and distributing electric energy to use, and use department also has higher requirement to vacuum circuit-breaker.Vacuum circuit-breaker because of its arc-extinguishing medium and arc extinguishing after the dielectric in contact gap all be that high vacuum is gained the name; It has volume little, lightweight, be applicable to the advantage that frequent operation, arc extinguishing need not overhaul, in power distribution network, use comparatively universal.The common more complicated of the tripping mechanism of existing vacuum circuit-breaker, installation trouble, the production and processing cost compare is high.
Summary of the invention
Be the common more complicated of tripping mechanism that solves existing vacuum circuit-breaker in the background technology, the problem that trouble is installed, the utility model provides a kind of vacuum circuit-breaker.
The technical solution of the utility model is: a kind of vacuum circuit-breaker, comprise spring operating mechanism and tripping mechanism, described tripping mechanism is installed on the spring operating mechanism, described tripping mechanism links by buckle and spring operating mechanism, described tripping mechanism comprises installing rack, described installing rack is provided with the dropout semiaxis, be used for installing the buckle installation shaft of buckle, the first limit shaft and the second limit shaft, described buckle one end blocks mutually with the dropout semiaxis, the other end of buckle and the rocking arm on the spring operating mechanism offset, described dropout semiaxis caves inward and forms a plurality of gap slots, the downside of one an end gap slot located therein of described buckle is equipped with limiting plate and dropout plate in the described gap slot.
As a kind of improvement of the present utility model, described limiting plate has the second place after the primary importance of blocking mutually with the first limit shaft and tripping mechanism are threaded off.
As further improvement of the utility model, described dropout plate has the primary importance and the second place of blocking mutually with the second limit shaft when not threading off.
As further improvement of the utility model, described limiting plate is " 7 " font.
As further improvement of the utility model, described dropout plate is " V " font.
As further improvement of the utility model, described the second limit shaft is the stud limit shaft.
As further improvement of the utility model, be provided with deep groove ball bearing between described buckle installation shaft and the installing rack.
The beneficial effects of the utility model are, the design of gap slot does not take the space of tripping mechanism so that limiting plate and dropout plate are easy for installation, and the utility model is relatively simple for structure, easy for installation simultaneously, and it is reliable to thread off, and tripping mechanism and operating mechanism interlock are reliable.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Accompanying drawing 2 is the structural representation in the utility model installing rack 2.
Among the figure, 1, buckle; 2, installing rack; 3, dropout semiaxis; 31, gap slot; 4, buckle installation shaft; 5, the first limit shaft; 6, the second limit shaft; 7, limiting plate; 8, dropout plate; 9, deep groove ball bearing.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
By Fig. 1 in conjunction with shown in Figure 2, a kind of vacuum circuit-breaker, comprise spring operating mechanism and tripping mechanism, described tripping mechanism is installed on the spring operating mechanism, described tripping mechanism links by buckle 1 and spring operating mechanism, described tripping mechanism comprises installing rack 2, described installing rack 2 is provided with dropout semiaxis 3, is used for installing buckle installation shaft 4, the first limit shaft 5 and second limit shaft 6 of buckle 1, specifically, be provided with deep groove ball bearing 9 between described buckle installation shaft 4 and the installing rack 2.Specifically, described the second limit shaft 6 is the stud limit shaft.Described buckle 1 one ends block mutually with dropout semiaxis 3, the other end of buckle 1 and the rocking arm on the spring operating mechanism offset, described dropout semiaxis 3 caves inward and forms a plurality of gap slots 31, the downside (referring to accompanying drawing 2) of one an end gap slot 31 located therein of described buckle 1, when threading off, 3 rotations of dropout semiaxis, the position of the buckle 1 corresponding dropout semiaxis 3 that originally block mutually with dropout semiaxis 3 this moment is gap slot 31 places of dropout semiaxis 3, at this moment, buckle 1 can not block mutually with dropout semiaxis 3, buckle 1 rotation is so that the spring operating mechanism motion.Limiting plate 7 and dropout plate 8 are installed in the described gap slot 31, and described limiting plate 7 is " 7 " font, and described dropout plate 8 is " V " font.The beneficial effects of the utility model are, the design of gap slot does not take the space of tripping mechanism so that limiting plate and dropout plate are easy for installation, and the utility model is relatively simple for structure, easy for installation simultaneously, and it is reliable to thread off, and tripping mechanism and operating mechanism interlock are reliable.
As shown in Figure 1, described limiting plate 7 has the second place after the primary importance of blocking mutually with the first limit shaft 5 and tripping mechanism are threaded off, and described dropout plate 8 has the primary importance and the second place of blocking mutually with the second limit shaft 6 when not threading off.Such structure is so that product has good limit function by limiting plate when locking, and the semiaxis of avoiding threading off rotates excessively, and dropout plate and the second limit shaft cooperate, so that the good limit function of product, the semiaxis of avoiding threading off rotates excessively.What provide among Fig. 1 is that limiting plate is in primary importance, and the dropout plate is in primary importance.Such structure is so that the rotation of dropout semiaxis all the time can be by well spacing, and the semiaxis of avoiding threading off rotates excessively.
Every technical staff's notice: although the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
