Abstract
The utility model discloses an insulating pad of a transformer. The insulating pad comprises a pad body, wherein a radiating groove is formed on a part, used for supporting a coil, of the pad body; and through holes communicated with the radiating groove are formed in the periphery of the pad body. Because the radiating groove is formed in the pad body, the contact area between the pad body and the coil is greatly reduced, the radiation requirement on the part of the coil is met, and the mounting of a supporting bar and the structural strength of the pad are not affected.
Description
Technical field
The utility model relates to the cross-over block of transformer insulated parts, particularly transformer.
Background technology
In the present transformer production process, because insulation and Equipment Requirement all can add stay and the cushion block that cooperates with stay on coil.But along with the increase of transformer capacity, its caloric value is also increasing, and generally, coil normally is close to the cushion block surface, can't satisfy the heat radiation requirement at this position.
Summary of the invention
The utility model problem to be solved just provides a kind of transformer insulated cushion block, can effectively improve the radiating effect of cushion block and coil contact site, guarantees the operation of transformer long-term safety.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of transformer insulated cushion block, comprise the cushion block body, and it is characterized in that: the position that the cushion block body is used for support coil is provided with the radiating groove of indent.
Further, be provided with the through hole that communicates with radiating groove around the said cushion block body.
Further, said radiating groove is designed to unlimited up and down through-hole type structure.
The beneficial effect of the utility model: owing to be provided with radiating groove on the cushion block body, the contact area of cushion block body and coil reduces greatly, has satisfied the heat radiation requirement at this position of coil, but does not influence the installation of stay and the structural strength of cushion block.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two.
Embodiment
With reference to Fig. 1,
Embodiment one: a kind of transformer insulated cushion block, comprise cushion block body 1, and the position that cushion block body 1 is used for support coil 2 is provided with the radiating groove 11 of indent, is the slot 12 that the plug-in mounting stay is used at an end of cushion block body 1.
With reference to Fig. 2,
Embodiment two: on the basis of embodiment one, be provided with the through hole 13 that communicates with radiating groove 11 around the cushion block body 1, to improve radiating effect.
Embodiment three: on embodiment one or two basis, radiating groove 11 is designed to unlimited up and down through-hole type structure, raising radiating effect further.
In the foregoing description, the shape of radiating groove 11 does not limit, and can squarely can be circular yet.
Claims (3)
1. a transformer insulated cushion block comprises cushion block body (1), it is characterized in that: the position that cushion block body (1) is used for support coil (2) is provided with the radiating groove (11) of indent.
2. a kind of transformer insulated cushion block according to claim 1 is characterized in that: said cushion block body (1) is provided with the through hole (13) that communicates with radiating groove (11) on every side.
3. a kind of transformer insulated cushion block according to claim 1 and 2 is characterized in that: said radiating groove (11) is designed to unlimited up and down through-hole type structure.
