Abstract
The utility model discloses a kind of flow-guiding structure of primary cut-out, comprise top, middle part, step, bottom, top is positioned at the top at middle part, step is between middle part and bottom, the top on top is provided with the first screw hole, and the side on top is provided with the second screw hole and the 3rd screw hole, and middle part is provided with a groove, bottom is provided with breach and location hole, and breach is positioned at the top of location hole.The flow-guiding structure of the utility model primary cut-out is convenient to be fixed with other element, is less likely to occur to come off.
Description
Technical field
The utility model relates to a kind of flow-guiding structure 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 flow-guiding structure of existing primary cut-out is inconvenient to be fixed with other element, easily comes off.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of flow-guiding structure of primary cut-out, and it is conveniently fixed with other element, is less likely to occur to come off, 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 flow-guiding structure of primary cut-out, it is characterized in that, comprise top, middle part, step, bottom, top is positioned at the top at middle part, step is between middle part and bottom, the top on top is provided with the first screw hole, and the side on top is provided with the second screw hole and the 3rd screw hole, and middle part is provided with a groove, bottom is provided with breach and location hole, and breach is positioned at the top of location hole.
As further improvement of the utility model, the shape of described groove is rectangle.
As further improvement of the utility model, the shape on described top is rectangle, and the shape at middle part, the shape of bottom are all cylindrical.
As further improvement of the utility model, the diameter at described middle part is greater than the diameter on top, and the diameter of bottom is greater than the diameter at middle part.
Beneficial effect: compared with prior art, it has following beneficial effect to the utility model:
The flow-guiding structure of the utility model primary cut-out increases function, and convenient and other element is fixed, and is less likely to occur to come off, 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 flow-guiding structure of primary cut-out.
Embodiment
Consult Fig. 1, a kind of flow-guiding structure of primary cut-out, comprise top 1, middle part 2, step 3, bottom 4, top 1 is positioned at the top at middle part 2, and step 3 is between middle part 2 and bottom 4, and the top on top 1 is provided with the first screw hole 5, the side on top 1 is provided with the second screw hole 6 and the 3rd screw hole 7, middle part 2 is provided with a groove 8, and bottom 4 is provided with breach 9 and location hole 10, and breach 9 is positioned at the top of location hole 10.First screw hole can facilitate in the vertical to be fixed with other elements, and the second screw hole and the 3rd screw hole are convenient in the horizontal to be fixed with other elements, and location hole can position in bottom and other element, and breach is convenient chimeric with other elements.
As preferably, the shape of groove 8 is rectangle, chimeric with other element like this, prevents transverse shifting.
As preferably, the shape on top 1 is rectangle, and the shape at middle part 2, the shape of bottom 4 are all cylindrical, conveniently like this coordinates with other element.
As preferably, the diameter at middle part 2 is greater than the diameter on top 1, and the diameter of bottom 4 is greater than the diameter at middle part 2.
In sum, the flow-guiding structure of the utility model primary cut-out increases function, and convenient and other element is fixed, and is less likely to occur to come off, 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.
