Abstract
The utility model discloses a coil brace of a dry transformer, which comprises a brace main body. The left side face, the right side face and the upper surface of the brace main body are plane; an opening with a reverse V-shaped cross section is arranged at the lower end of the brace main body; and mutually symmetrical first and second support planes are arranged at two sides of the lower end of the opening. The coil brace has the advantages that the upper surface of the coil brace is plane, which is good for winding the coil; the reverse V-shaped opening forms an air channel, which is good for heat dissipation of the inner coil; and the mutually symmetrical first and second support planes are arranged at two sides of the lower part of the opening, which can improve the stability of the coil brace.
Description
Technical field
The utility model relates to a kind of stay that is used on the transformer, relates in particular to a kind of coil stay that is used on the dry-type transformer.
Background technology
Coil stay is arranged between the exterior loop and interior loop in the dry-type transformer.The cross section of existing coil stay is generally rounded, oval, rectangle, I-shaped, T font etc., and the coil stay function of these several shapes is all more single, can not satisfy the requirements such as coiling, stability of interior loop heat radiation, exterior loop simultaneously.
The utility model content
Technical problem to be solved in the utility model is: the coil stay on the dry-type transformer of being used in that a kind of favourable and interior loop heat radiation, exterior loop coiling, good stability are provided.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: be used in the coil stay on the dry-type transformer, comprise: the stay body, the left surface of described stay body, right flank and upper surface are the plane, offer the opening that cross section is inverted v-shaped in the lower end of stay body, be provided with the first symmetrical supporting plane and second supporting plane in the both sides, lower end of opening.
The utility model has the advantages that: this structure be used in coil stay on the dry-type transformer, because thereby its upper surface is the coiling that the plane helps exterior loop, the opening of inverted v-shaped forms air flue and helps the interior loop heat radiation, be provided with the first symmetrical supporting plane and second supporting plane in the both sides, lower end of opening, can improve the stability of coil stay.
Description of drawings
Fig. 1 is used in the cross-sectional structure schematic diagram of the coil stay on the dry-type transformer for the utility model.
Among the figure: 1, stay body, 11, left surface, 12, right flank, 13, upper surface, 141, opening, 142, first supporting plane, 143, second supporting plane.
Embodiment
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, be used in the coil stay on the dry-type transformer, comprise: stay body 1, the left surface 11 of described stay body 1, right flank 12 and upper surface 13 are the plane, offer cross section in the lower end of stay body 1 and be the opening 141 of inverted v-shaped, be provided with the first symmetrical supporting plane 142 and second supporting plane 143 in the both sides, lower end of opening 141.
This structure be used in coil stay on the dry-type transformer, because thereby its upper surface 13 helps the coiling of exterior loop for the plane, the opening 141 of inverted v-shaped forms air flue and helps the interior loop heat radiation, be provided with the first symmetrical supporting plane 142 and second supporting plane 143 in the both sides, lower end of opening 141, can improve the stability of coil stay.
Claims (1)
1, is used in coil stay on the dry-type transformer, comprise: stay body (1), it is characterized in that: the left surface (11) of described stay body (1), right flank (12) and upper surface (13) are the plane, offer cross section in the lower end of stay body (1) and be the opening (141) of inverted v-shaped, be provided with symmetrical first supporting plane (142) and second supporting plane (143) in the both sides, lower end of opening (141).
