Abstract
The invention discloses a connecting apparatus of a high-voltage circuit breaker and a making method thereof. The connecting apparatus comprises a head portion, a middle portion, and a tail portion; and the middle portion is arranged between the head portion and the tail portion. A first baffle plate and a second baffle plate are sleeved at the middle portion; a first groove is formed between the first baffle plate and the second baffle plate; and a second groove is formed between the second baffle plate and the tail portion. A screw hole is formed in one end of the tail portion. With the connecting apparatus, shedding can be prevented; connection is firm; and the working effect of the high-voltage circuit breaker can be ensured.
Description
Technical field
The present invention relates to a kind of jockey and manufacture method thereof of primary cut-out.
Background technology
Primary cut-out (or claim high-voltage switch gear) not only can cut off or closed high circuit in zero loadElectric current and load current, and in the time that system breaks down by the effect of relay protection, cutDisconnected overload electric current and short circuit current, it has quite perfect arc extinguishing structure and enough cutout abilities,Can be divided into: (SF6 is disconnected for oil-break (bulk oil circuit, oil-minimum breaker), sulfur hexafluoride breakerRoad device), vacuum circuit breaker, compressed-air circuit breaker etc. The jockey of existing primary cut-out is easyCome off, connect insecure.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of primary cut-out jockey andManufacture method, the jockey of this primary cut-out can not come off, and is connected firmly.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: Yi ZhonggaoThe jockey of voltage breaker, comprises head, middle part, afterbody, middle part between head and afterbody,On middle part, cover has first baffle plate and a second baffle, between the first baffle plate and second baffle, is provided withThe first groove, is provided with the second groove between second baffle and afterbody, one end of afterbody is provided with a screwHole.
As a further improvement on the present invention, the diameter of described head is less than the diameter at middle part, middle partDiameter is less than the diameter of afterbody.
As a further improvement on the present invention, one end of described afterbody is provided with rounding.
As a further improvement on the present invention, the diameter phase of the diameter of described the first baffle plate and second baffleWith, the diameter of the first baffle plate is greater than the diameter at middle part.
The present invention also provides a kind of manufacture method of jockey of primary cut-out, it is characterized in that,Comprise the following steps: cylindrical insulation bar is cut and forms head, middle part, afterbody, thenOn middle part, drill flute forms the first groove and the second groove, and then on afterbody, boring forms screw hole,After on afterbody cutting form rounding.
Beneficial effect: compared with prior art, it has following beneficial effect in the present invention:
The jockey of primary cut-out of the present invention can not come off, and is connected firmly, and has ensured high pressureThe working effect of breaker.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, of the present invention in order to better understandTechnological means, and can being implemented according to the content of description, and for allow of the present invention above-mentioned andOther objects, feature and advantage can become apparent, below especially exemplified by preferred embodiment, and coordinate attachedFigure, is described in detail as follows.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram of the jockey of primary cut-out of the present invention.
Detailed description of the invention
Consult Fig. 1, the jockey of primary cut-out of the present invention comprises head 10, middle part 20, afterbody30, middle part 20 is between head 10 and afterbody 30, and on middle part 20, cover has first baffle plate 21With between a second baffle 22, the first baffle plates 21 and second baffle 22, be provided with the first groove 23, theBetween two baffle plates 22 and afterbody 30, be provided with the second groove 24, one end of afterbody 30 is provided with a screwHole 31. Described head 10, middle part 20, afterbody 30 are all to be formed by the manufacture of Q235B material, Q235BMaterial is a kind of carbon structural steels, has percentage elongation, intensity and good toughness well. FirstGroove and the second groove are convenient to be fixed with other elements, fixed; In addition screw hole convenient withThe securing members such as screw are fixed, and so just can not come off, and are connected firmly.
As preferably, the diameter of head 10 is less than the diameter at middle part 20, and the diameter at middle part 20 is less thanThe diameter of afterbody 30, the two ends of the convenient like this jockey of distinguishing primary cut-out, prevent wrong.
As preferably, one end of afterbody 30 is provided with rounding 32, so can be by copper cash scratch, scrapeDisconnected, thus ensure that the structure of primary cut-out is good.
As preferably, the diameter of the first baffle plate 21 is identical with the diameter of second baffle 22, the first baffle plate21 diameter is greater than the diameter at middle part 20, and engaging is more firm like this.
The manufacture method of the jockey of primary cut-out of the present invention comprises the following steps: by cylindrical exhaustedEdge bar cuts and forms head, middle part, afterbody, then on middle part drill flute form the first groove andThe second groove, then on afterbody, boring forms screw hole, and finally on afterbody, cutting forms rounding.
In sum, the jockey of primary cut-out of the present invention can not come off, be connected firmly,Ensure the working effect of primary cut-out.
Embodiment recited above is described the preferred embodiment of the present invention, not rightThe spirit and scope of the present invention limit. Do not departing under the prerequisite of design concept of the present invention abilityVarious modification and improvement that territory ordinary person makes technical scheme of the present invention, all should drop into thisBright protection domain, the technology contents of request protection of the present invention, has all been documented in claimsIn.
