Abstract
The utility model provides a large-current casted pole vacuum breaker, the rated current of which is 3150A and the electric part of which comprises three poles, and each pole comprises a vacuum arc extinguish chamber, an upper conducting part and a lower conducting part. The vacuum breaker has the following characteristics: the vacuum arc extinguish chamber, the upper conducting part and the lower conducting part are integrally casted with resin to form the pole, and the distance between the centers of each two adjacent poles is 230mm. Since the poles is formed by resin casting, the dimension of each pole is greatly reduced, correspondingly, the distance between the centers of each two adjacent poles can be greatly reduced, thereby, the width of the body of a high-voltage switch cabinet containing the breaker can be reduced as well, and therefore the miniaturization of the high-voltage switch cabinet is finally realized.
Description
Technical field
The utility model relates to a kind of high-pressure vacuum switch, relates in particular to a kind of big electric current cast pole type vacuum circuit-breaker.
Background technology
In electric power system, circuit breaker is widely used as power distribution equipment, in a large amount of vacuum circuit-breakers that use, generally comprises three phase posts with vacuum interrupter at present.In existing rated current is in the vacuum circuit-breaker of 3150A, the volume of phase post is relatively large, the centre distance of adjacent phase post mostly is 275mm, the centre distance of adjacent phase post is big relatively, make that whole vacuum circuit-breaker volume is big, when being contained in vacuum circuit-breaker in the high-tension switch cabinet, can not make the high-tension switch cabinet miniaturization.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of big electric current cast pole type vacuum circuit-breaker, and its energy minification is beneficial to the miniaturization of high pressure beginning cabinet.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of big electric current cast pole type vacuum circuit-breaker, and the rated current of described vacuum circuit-breaker is 3150A; Electric part comprises the pole that three poured with epoxy resin become, each pole comprises vacuum interrupter, upward electric-conductor reaches electric-conductor down, described vacuum interrupter, last electric-conductor and following electric-conductor are integral by poured with epoxy resin and form pole, and the centre-to-centre spacing of two neighboring pole post is 230mm.
The beneficial effects of the utility model are: owing to come the moulding pole by resin-cast, make the pole size greatly reduce, correspondingly, can dwindle the centre-to-centre spacing of two neighboring pole post greatly, thereby also can dwindle the cabinet width of the high-tension switch cabinet that loads described circuit breaker, and then finally realize the high-tension switch cabinet miniaturization.
Description of drawings
Fig. 1 is the cross-sectional schematic of first preferred implementation of the utility model.
Fig. 2 is the schematic top plan view of middle vacuum circuit-breaker embodiment illustrated in fig. 1.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and the embodiments.Should be appreciated that embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Seeing also Fig. 1 and Fig. 2, is a preferred implementation of the big electric current cast of the utility model pole type vacuum circuit-breaker, and the rated current of the vacuum circuit-breaker in the present embodiment is 3150A.The electric part of described vacuum circuit-breaker comprises three poles 1, and the centre-to-centre spacing of adjacent pole 1 is 230mm.
Each pole 1 comprises a vacuum interrupter 2, goes up electric-conductor 3, electric-conductor 4 down, described vacuum interrupter 2, go up electric-conductor 3 and down electric-conductor 4 become the whole described pole 1 that forms by poured with epoxy resin.The diameter of described vacuum interrupter 2 is 122mm only, described vacuum interrupter 2 comprises fixed contact (not shown) and moving contact 20, described fixed contact is fixed on the electric-conductor 3, and moving contact 20 is connected with following electric-conductor 4 by the soft binding 5 of hat type, constitutes the galvanic circle thus.Described vacuum circuit-breaker also comprises a pull bar 6, and an end of described pull bar 6 is connected with moving contact 20, and an end is connected with operating mechanism 7.
Described vacuum circuit-breaker is by the closure and the disjunction of vacuum interrupter 2 burden circuit, during work, fixed contact contacts with moving contact 20, forms conductive path, electric current flow to the moving contact 20 of vacuum interrupter 2 from last electric-conductor 3 by fixed contact, again to being flexible coupling 5 and electric-conductor 4 down; When disconnecting vacuum circuit-breaker, pulling pull bar 6 makes fixed contact separate with moving contact 20 and gets final product.
The vacuum interrupter of above-mentioned vacuum circuit breaker polar, go up electric-conductor 3 and down electric-conductor 4 become the whole pole 1 that forms by poured with epoxy resin, can reduce parts, simplified structure makes that the volume of pole 1 is little, thus, the centre-to-centre spacing of two neighboring pole post 1 can correspondingly be contracted to 230mm.Correspondingly, the cabinet width that loads the high-tension switch cabinet of described vacuum circuit-breaker also just can greatly reduce, corresponding to the high-tension switch cabinet cabinet of the pole centre-to-centre spacing of 230mm wide only be 850mm, thereby realize the high-tension switch cabinet miniaturization.
The above only is a preferred implementation of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
