Abstract
The utility model relates to a framework structure for a forced air cooling dry type transformer air guiding cylinder, and belongs to the technical field of transformer production. The technical scheme is that the framework structure comprises a coil insulation cylinder (1), a first n-shaped strut (3), a second n-shaped strut (5), a cushion block (4), a wire pie (2), and an air guiding cylinder (6), wherein T-shaped notches are arranged both on the inner side of the cushion block and the outer side of the cushion block, the first n-shaped strut is placed on the coil insulation cylinder, the T-shaped notch on the inner side of the cushion block is sleeved on the first n-shaped strut, the wire pie is wound outside the T-shaped notch in the inner side of the cushion block, and the second n-shaped strut is sleeved on the T-shaped notch on the outer side of the cushion block to form the framework of the air guiding cylinder. The air guiding cylinder is wound outside the second n-shaped strut. The framework structure for the forced air cooling dry type transformer is convenient to machine and manufacture, and solid and reliable in performance, and for a dry type transformer provided with a forced air cooling device, the framework structure is high in guiding efficiency of air flow, obvious in heat-dissipating effect, and especially applicable to the forced air cooling dry type transformer.
Description
Technical field
The utility model relates to a kind of skeleton structure of forced air cooling dry-type transformer ventilating duct, belongs to the transformer production technical field.
Background technology
For dwindling the volume of transformer, improve space availability ratio, many dry-type rectifier transformers often need to use forced air cooling device, this forced air cooling device needs transformer body is installed additional ventilating duct and deep bead, so that the air stream by transformer body is carried out forced guiding, the heat that distributes when being beneficial to take away quickly transformer work.The design of background technology forced air cooling ventilating duct is placed some stays at coil surface often, and coiling ventilating duct outside stay when voltage levvl is higher, can form creepage phenomenon on the stay surface that coil surface is placed.
The utility model content
The purpose of this utility model provides a kind of skeleton structure of forced air cooling dry-type transformer ventilating duct, and processing and fabricating is convenient, and performance is solid reliable, and high to the boot efficiency of air stream, radiating effect is obvious, solves the problems referred to above that background technology exists.
The technical solution of the utility model is: a kind of skeleton structure of forced air cooling dry-type transformer ventilating duct, comprise coil insulation cylinder, a few font stay one, a few font stay two, cushion block, line cake and ventilating duct, the inboard of cushion block and the outside are equipped with the T-slot mouth, place a few font stays one on the coil insulation cylinder, the inboard T-slot mouth of cushion block is through on a few font stays one, outside wrap wire cake, a few font stays two are through on the outside T-slot mouth of cushion block, consist of the skeleton of ventilating duct, ventilating duct is twined in a few font stays two outsides.
A few font stays one and a few font stay two are in full accord, and the T-slot mouth of the inboard of cushion block and arranged outside is also in full accord, and several character form structures of a few font stays and the T-slot mouth of cushion block mate mutually.
A few font stays one, a few font stay two and cushion block are the H class F insulating material F and are made; Ventilating duct is the coiling of H level preimpregnation TFT material, and behind hyperthermia drying, preimpregnation material can be bonded into solid tubular.
Good effect of the present utility model: a few font stays one and a few font stay two are equivalent to hollow stay, and hot-air can be taken away heat in a few font stay notch internal circulations, more is conducive to the heat radiation of dry-type transformer; Consisted of the solid skeleton of ventilating duct by a few font stays one, a few font stay two and cushion block, the ventilating duct that coiling forms on this skeleton, have that processing and fabricating is convenient, performance solid reliable, to high, the obvious characteristics of radiating effect of boot efficiency of air stream, be highly suitable for forced air cooling formula dry-type transformer.
