Abstract

The utility model discloses a kind of cover of primary cut-out, comprise cover body, bend, base, the top of bend and cover body is fixed, and the bottom of base and cover body is fixed, and bend forms a groove, and base is provided with a through hole.The cover of the utility model primary cut-out is convenient to be engaged with other element, is less likely to occur to loosen.

Description

The cover of primary cut-out

Technical field

The utility model relates to a kind of cover 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 (SF6 circuit breaker), vacuum circuit-breaker, compressed-air circuit breaker etc.The cover inconvenience of existing primary cut-out engages with other element, easily occurs to loosen.

Utility model content

The utility model, for the deficiencies in the prior art, provides a kind of cover of primary cut-out, and it conveniently engages with other element, is less likely to occur to loosen, ensure that the working effect of primary cut-out.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of cover of primary cut-out, it is characterized in that, comprise cover body, bend, base, the top of bend and cover body is fixed, the bottom of base and cover body is fixed, and bend forms a groove, and base is provided with a through hole.

As further improvement of the utility model, described base is also provided with multiple location notch.

As further improvement of the utility model, the quantity of described location notch is ten.

Compared with prior art, it has following beneficial effect to the utility model: the cover of the utility model primary cut-out increases function, conveniently engages with other element, is less likely to occur to loosen, 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 cover of primary cut-out.

Fig. 2 is the structural representation of base in the utility model.

Embodiment

Consult Fig. 1 and Fig. 2, a kind of cover of primary cut-out, comprise cover body 1, bend 3, base 4, bend 3 is fixed with the top of cover body 1, and base 4 is fixed with the bottom of cover body 1, and bend 3 forms a groove 2, and base 4 is provided with a through hole 5.Bend, groove are convenient to be engaged with other element, is less likely to occur to loosen, ensure that the working effect of primary cut-out.Through hole and other element are socketed, and prevent transverse shifting.

As preferably, base 4 is also provided with multiple location notch 6, convenient like this and other element is located.

As preferably, the quantity of location notch 6 is ten, rationally most economical like this.

In sum, the cover of the utility model primary cut-out increases function, conveniently engages with other element, is less likely to occur to loosen, 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.
