Description
Technical field
The utility model relates to dry-type transformer, especially about the structure that cools of dry-type transformer.
Background technology
The cooling structure of conventional dry transformer is: bottom is provided with transverse fan, and coil top 1/3 place is provided with horizontal deep bead (or not establishing), and transformer cabinet top is provided with air exhauster.Transformer is when normally running, and bottom fan starting forces wind to circulate, and wind passes through from the slit between deep bead and coil through horizontal deep bead, and hot blast is taken away by top blower fan, reduces coil temperature rise with this.
When wind passes through from the slit between deep bead and coil, originally be want to utilize valley effect to be flowed fast through by wind, but actual conditions are, because wind is subject to the stop of horizontal deep bead, part wind does not pass through from the slit between deep bead and coil, but form a circulation at horizontal deep bead place, make wind cannot take away heat in time.Due to collecting in a large number of heat, make transformer coil local temperature too high.Cause coil minor insulation heat ageing, have a strong impact on transformer useful life, this phenomenon is very general.In addition, can not seal completely in reality between deep bead and transformer cabinet, part wind flows away in vain from the gap between deep bead and transformer cabinet, reduces the utilance of blower fan.
Summary of the invention
Main purpose of the present utility model is to provide a kind of structure that cools of new dry-type transformer, saves bottom blower fan, is more conducive to the ventilation and heat of transformer.
The utility model by the following technical solutions and technical measures realize.
The utility model proposes a kind of structure that cools of dry-type transformer, comprise the air exhauster at dry-type transformer cabinet top and be fixed on the soft insulation screen arranged between cabinet and dry-type transformer and around dry-type transformer periphery, this soft insulation screen is provided with multiple fairlead and its upper end connects cabinet top, air exhauster is just to dry-type transformer, be provided with air flue between soft insulation screen and dry-type transformer, the wind of bottom air inlet mouth is dispelled the heat to dry-type transformer by air flue.
Preferably, be arranged with multiple insulation fagging outside dry-type transformer, described soft insulation screen is fixed by insulation fagging.
Preferably, described insulation fagging is provided with multiple screwed hole, and soft insulation screen is fixed on by the nylon bolt coordinated with screwed hole and insulate on fagging.
Compared with prior art, the utility model at least has following beneficial effect:
1, the soft insulation screen installed around the periphery of dry-type transformer has insulation effect, can reduce the insulation distance between dry-type transformer and cabinet, dry-type transformer cabinet size is diminished, saves installing space and cost, improve the competitiveness of product;
2, compared with prior art, eliminate bottom blower fan, save the set-up time, for making full use of the air exhauster at dry-type transformer cabinet top, soft insulation screen directes reach transformer case top, and air exhauster is just to dry-type transformer, bottom air inlet mouth is without the obstruction of blower fan, the intake of air flue increases greatly, is more conducive to the ventilation and heat of dry-type transformer, reduces temperature rise;
3, soft insulation screen is fixed on insulation fagging by nylon bolt, and fixation is reliable.

Embodiment
Technical characteristic of the present utility model is further described below in conjunction with embodiment.
The structure that cools is the important feature of dry-type transformer.The structure that cools of the utility model dry-type transformer comprises the air exhauster 2 at dry-type transformer 4 cabinet 1 top and is fixed on the soft insulation screen 3 arranged between cabinet 1 and dry-type transformer 4 and around transformer periphery.The soft insulation screen 3 installed around the periphery of dry-type transformer 4 has insulation effect, can reduce the insulation distance between dry-type transformer 4 and cabinet 1, and dry-type transformer 4 cabinet 1 size is diminished, and saves installing space and cost, improves the competitiveness of product.
In the periphery of dry-type transformer 4, multiple insulation fagging 8 is set, dry-type transformer 4 entirety is enclosed one week by the soft insulation screen 3 be fixed on outside insulation fagging 8, screwed hole opened by insulation fagging 8, soft insulation screen 3 is fixed on by the nylon bolt 9 coordinated with screwed hole and insulate on fagging 8, fixation is reliable, keep certain distance as air flue between soft insulation screen 3 and dry-type transformer 4, the wind of dry-type transformer 4 bottom air inlet mouth is dispelled the heat to transformer by air flue.
This soft insulation screen 3 offers multiple fairlead 7, and the lead-in wire 6 of dry-type transformer is connected with terminal block 5 by fairlead 7.Compared with prior art, eliminate bottom blower fan, save the set-up time, for making full use of the air exhauster 2 at dry-type transformer 4 cabinet 1 top, dry-type transformer 4 cabinet 1 top is directed reach in the upper end of soft insulation screen 3, and the air exhauster 2 at cabinet 1 top is just to dry-type transformer 4 body, dry-type transformer 4 bottom air inlet mouth is without the obstruction of blower fan, the intake of air flue increases greatly, is more conducive to the ventilation and heat of dry-type transformer 4, reduces temperature rise.
