Abstract
The utility model relates to a hollow pad for disc coils of a dry type transformer, which belongs to the molded insulator. The hollow pad is characterized in that a support part of the pad for spaced arrangement of discs of disc coils is of a hollow shape. Due to the hollow structure of the pad, the utility model is particularly conducive to the improvement of dry type transformer cooling conditions.
Description
Affiliated technical field:
A kind of empty shape cushion block that is used for the dry-type transformer disc coil, the insulating part for moulding article is characterized in that: it is empty shape form that this cushion block is used for the support zone that disc coil line cake puts at interval.
Background technology:
The existing dry-type transformer disc coil line cake that is used for is put the molding cushion block goods that support usefulness at interval, because its support zone is enclosed planar, so this position has hidden the corresponding radiating surface of winding wire cake fully.
Summary of the invention:
In order to overcome existing this molding cushion block goods as insulating part, hidden this deficiency of the unfavorable abundant heat radiation of radiating surface of disc coil line cake fully because of the support zone that is enclosed planar, the utility model provides a kind of empty shape cushion block that is used for the dry-type transformer disc coil, it is characterized in that: the support zone of this cushion block is empty shape form, because this built on stilts effect that is sky shape form, still kept certain radiating surface, therefore can substantially improve the radiating condition of dry-type transformer at support zone.
This cushion block of the present utility model, its support zone are empty shape form.
Description of drawings:
Fig. 1 is the empty shape cushion block embodiment global shape figure of first dry-type transformer disc coil
Among Fig. 1,1. empty shape cushion block body is 2. inlayed notch, 3. support zone.
Fig. 2 is the sectional drawing of this cushion block at the A-A place
Concrete implementing method:
In Fig. 1: in empty shape cushion block body (1) global shape, be provided with the general support zone (3) inlaying notch (2) and benefit line cake heat radiation combined with dry-type transformer disc coil structural requirement.
In Fig. 2: the section by the A-A place shows: empty shape cushion block body (1) is flat shape.
Claims (1)
1. an empty shape cushion block that is used for the dry-type transformer disc coil is the moulding article insulating part, it is characterized in that: it is empty shape form that this cushion block is used for the support zone that disc coil line cake puts at interval.
