Abstract
The power transformer skeleton that the utility model discloses a kind of anti-short circuit, belongs to field transformer.Comprise two wires, skeleton, crossed beam trunking and iron core outrigger that the each extension of primary coil and secondary coil goes out, wherein, the edge-smoothing of described crossed beam trunking, and notch is circular-arc; Between described crossed beam trunking and iron core outrigger, be provided with reinforcement, reinforcement has one end of height to be close to iron core outrigger, i.e. reinforcement rectangular triangle in the time of side-looking.Skeleton of the present utility model is difficult for the Wire sheath incised wound through its crossed beam trunking, when can making to interfix between skeleton and iron core outrigger, also makes iron core outrigger not have the accidents such as short circuit and occurs simultaneously, has improved the fail safe of use.
Description
Technical field
The utility model relates to field transformer, is specifically related to a kind of power transformer skeleton of anti-short circuit.
Background technology
The skeleton of traditional power transformer is all to have corresponding crossed beam trunking at the root of the wire of primary coil and secondary coil extension.But the notch of this crossed beam trunking is vertical stratification; and comparatively sharp; permanent use easily cut off the rubber sheath of wire, and by out exposed its inner copper cash of protection that needs, and the exposed part of this copper cash can get more and more; simultaneously according to inertia; the exposed copper cash outside brandreth part of close iron core outrigger gradually, and do not establish the object that can stop between the two yet, if exposed copper cash is contacted with iron core outrigger; just very easily make power transformer short circuit, very dangerous.
Summary of the invention
The purpose of this utility model is according to the problems referred to above, and a kind of power transformer skeleton of anti-short circuit is provided, and this skeleton can be difficult for being cut open by crossed beam trunking by wire, is also difficult for making wire to contact with iron core outrigger.
For achieving the above object, the technical solution of the utility model is:
A kind of power transformer skeleton of anti-short circuit, comprise two wires, skeleton, crossed beam trunking and iron core outrigger that the each extension of primary coil and secondary coil goes out, it is characterized in that: the edge-smoothing of described crossed beam trunking, and it is circular-arc that notch is, notch is the 1/3-1/2 of crossed beam trunking flute length to the distance of iron core outrigger simultaneously; Between described crossed beam trunking and iron core outrigger, be provided with reinforcement, reinforcement has one end of height to be close to iron core outrigger, i.e. reinforcement rectangular triangle in the time of side-looking, and this reinforcement height is the 1/3-1/2 of the difference in height of the outer top of the trellis skeleton face corresponding to it of iron core.
Described skeleton is provided with same reinforcement on the two sides of not opening crossed beam trunking, also can make to interfix between skeleton and iron core outrigger, makes the iron core outrigger in coil can not depart from original position.
To be that plastic material of the same race is integrated form for described reinforcement and skeleton, and the outer rim of skeleton is also polished smoothly simultaneously, prevents that skeleton edge from hurting wire or user's hand.
Skeleton of the present utility model is difficult for the Wire sheath incised wound through its crossed beam trunking, the four sides of skeleton is equipped with reinforcement simultaneously, therefore when can making to interfix between skeleton and iron core outrigger, also can make copper cash exposed in wire can not touch iron core outrigger, make iron core outrigger not have the accidents such as short circuit and occur, improved the fail safe using.

Embodiment
Below with reference to the accompanying drawings, the utility model is further described.
A kind of power transformer skeleton of anti-short circuit, comprise two wires, skeleton (1), crossed beam trunking and iron core outrigger (2) outrigger that the each extension of primary coil and secondary coil goes out, the outside part of skeleton (1) is divided into 4 skeleton faces by described iron core outrigger (2) outrigger, and the corresponding skeleton face of wire (5) of the wire (5) of primary coil and secondary coil is uniform is co-located in a normal surface.The corner of described skeleton face is circular-arc, the skeleton (1) corresponding with wire (5) is provided with crossed beam trunking (3), this crossed beam trunking (3) is positioned at the arc edge of skeleton face corner, the edge of crossed beam trunking (3) is comparatively level and smooth simultaneously, notch is circular arc, can prevent the sheath of the wire by this crossed beam trunking (3) (5) to cut off.
Above-mentioned notch is the 1/3-1/2 of crossed beam trunking (3) flute length to the distance of iron core outrigger (2) outrigger, the i.e. width of reinforcement (4) between the two for this reason of this distance.Described reinforcement (4) rectangular triangle in the time of side-looking, be that it upwards vertical one end is close to iron core outrigger (2) outrigger, reinforcement (4) the upwards height of vertical end is the 1/3-1/2 of the difference in height of the skeleton face that the outer top of the trellis of iron core outrigger (2) is corresponding with it.
Described reinforcement (4) forms for plastic material of the same race is integrated with skeleton (1), can save the process of its manufacture.
Simultaneously, also be provided with same reinforcement (4) at the skeleton face of not opening crossed beam trunking (3), make all skeleton faces all there is same reinforcement (4) in identical position, can make skeleton (1) and iron core outrigger (2) interfix simultaneously, can not make the voltage transitions of power transformer unstable.
When the power transformer of the utility model skeleton is equipped with in use, power transformer is fixed, wire (5) can be corresponding with power transformer after crossed beam trunking (3) is fixing accordingly input circuit end and output circuit connect, even if use for a long time this power transformer to be also difficult for making the copper core of winding wire (5) and iron core outrigger (2) outrigger to touch mutually.
The above has only expressed preferred implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion, improvement and substitute, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
Claims (3)
1. the power transformer skeleton of an anti-short circuit, comprise two wires (5), skeleton (1), crossed beam trunking and iron core outrigger (2) that the each extension of primary coil and secondary coil goes out, it is characterized in that: the edge-smoothing of described crossed beam trunking, and it is circular-arc that notch is, notch is the 1/3-1/2 of crossed beam trunking flute length to the distance of iron core outrigger (2) simultaneously; Between described crossed beam trunking and iron core outrigger (2), be provided with reinforcement (4), reinforcement (4) has one end of height to be close to iron core outrigger (2), be reinforcement (4) rectangular triangle in the time of side-looking, and this reinforcement (4) is highly the 1/3-1/2 of the difference in height of iron core outrigger (2) top skeleton face corresponding to it.
2. the power transformer skeleton of a kind of anti-short circuit according to claim 1, is characterized in that: described skeleton (1) is provided with same reinforcement (4) on the two sides of not opening crossed beam trunking.
3. the power transformer skeleton of a kind of anti-short circuit according to claim 1, is characterized in that: described reinforcement (4) forms for plastic material of the same race is integrated with skeleton (1), and the outer rim of skeleton (1) is also polished smoothly simultaneously.
