Abstract
The utility model discloses a kind of insulating case of primary cut-out, comprise head and afterbody, head is provided with first through hole, and the shape of the first through hole is both sides shape is circle, and both sides shape is rectangle in addition; The outer surface of afterbody is provided with an annular groove, and the inside of afterbody is provided with second through hole.The insulating case of the utility model primary cut-out increases function, conveniently coordinates with other elements, ensure that the working effect of primary cut-out.
Description
Technical field
The utility model relates to a kind of insulating case of primary cut-out.
Background technology
Primary cut-out (or claim high-voltage switch gear) not only can cut off or no-load current in closed high circuit and load current; and when system jam by the effect of relay protection; cut off overload electric current and short circuit current; it has quite perfect arc extinguishing structure and enough cutout abilities, can be divided into: oil circuit breaker (bulk-oil circuit-breaker, oil-minimum breaker), sulfur hexafluoride breaker (SF
6circuit breaker), vacuum circuit-breaker, compressed-air circuit breaker etc.Insulating case is between the necessary element of primary cut-out, the function singleness of existing insulating case, and inconvenience coordinates with other elements.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of insulating case of primary cut-out, and the insulating case of this primary cut-out increases function, conveniently coordinates with other elements.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
An insulating case for primary cut-out, comprises head and afterbody, and head is provided with first through hole, and the shape of the first through hole is both sides shape is circle, and both sides shape is rectangle in addition; The outer surface of afterbody is provided with an annular groove, and the inside of afterbody is provided with second through hole.
As further improvement of the utility model, the diameter of described head is greater than the diameter of afterbody.
As further improvement of the utility model, the length of described afterbody is greater than the length of head.
As further improvement of the utility model, one end diameter of described head is greater than the other end of head, and the shape of afterbody is cylindrical.
Beneficial effect: compared with prior art, it has following beneficial effect to the utility model:
The insulating case of the utility model primary cut-out increases function, conveniently coordinates with other elements, ensure that the working effect of primary cut-out.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of specification, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the insulating case of primary cut-out.
Fig. 2 is the front view of the insulating case of primary cut-out.
Embodiment
Consult Fig. 1 and Fig. 2, a kind of insulating case of primary cut-out, comprise head 10 and afterbody 20, the shape that head 10 is provided with first through hole 40, first through hole 40 be both sides shape for circular, both sides shape is rectangle in addition; The outer surface of afterbody 20 is provided with an annular groove 30, and the inside of afterbody 20 is provided with second through hole 50.Annular groove is convenient chimeric with other elements, so conveniently coordinates with other elements.First through hole is convenient to be engaged with other elements, increases corresponding function like this, can save the retaining elements such as screw.Second through hole facilitates other elements to pass.Described head 10 and afterbody 20 are all formed by polyformaldehyde material manufacture, and polyformaldehyde material has insulating properties and fire line.
As preferably, the diameter of head 10 is greater than the diameter of afterbody 20, facilitates annular groove chimeric with other elements like this.
As preferably, the length of afterbody 20 is greater than the length of head 10, and such benefit ensures that the stroke of afterbody is large, and the consequence that primary cut-out finally also can not be caused not close, ensure that the working effect of primary cut-out.
As preferably, one end diameter of head 10 is greater than the other end of head 10, and the shape of afterbody 20 is cylindrical, like this can not by the contact arm scratch of primary cut-out, scrape disconnected, thus ensure that the structure of primary cut-out is excellent.
In sum, the insulating case of the utility model primary cut-out increases function, conveniently coordinates with other elements, ensure that the working effect of primary cut-out.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection range of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
