Description
Technical field
The utility model is related to a kind of dry-type transformer, specifically a kind of cooling device for dry-type transformer.
Background technology
Dry-type transformer is widely used in local lighting, skyscraper, airport, the place such as harbour CNC plant equipment, simply
Say that dry-type transformer just refers to the transformer that iron core and winding are not immersed in insulating oil.The type of cooling is divided into natural air cooling
（AN）With force air to cool down（AF）.During natural air cooling, transformer can the long-term continuous operation under rated capacity.Forced air cooling
When, transformer output capacity can improve 50%.Suitable for interrupted running overload, or emergent accident running overload；Due to excessively negative
Load loss and impedance voltage amplification are larger during lotus, in non-economy running status, therefore should not be at continuous mistake for a long time
Load operation.
The Chinese patent of Application No. 201310639864.3 discloses a kind of transformer radiator structure, and it includes radiating
Case, the outer surface of heat dissipation tank is provided with spaced fin, and transformer radiator is as in the heat dissipation tank full of heat eliminating medium
Portion, the side lower of heat dissipation tank is provided with heat eliminating medium entrance, and the side surface upper part of heat dissipation tank is exported provided with heat eliminating medium, fin edge
Vertical direction is arranged or horizontal direction arrangement, or the arrangement of flat spin shape.
The patent is disadvantageous in that：The transformer radiator structure is to being filled in heat dissipation tank by heat eliminating medium entrance
Heat eliminating medium, but need to regularly replace heat eliminating medium, labor intensive material resources, while heat eliminating medium is also to need cost, were used
Heat eliminating medium afterwards can not be recycled, and cause the wasting of resources；The transformer radiator structure, when changing heat eliminating medium, is to pass through
The new heat eliminating medium of heat eliminating medium outlet injection so that heat eliminating medium originally is exported by heat eliminating medium and discharged, until new
Untill heat eliminating medium is full of heat dissipation tank, when injecting new heat eliminating medium, heat eliminating medium originally may be without scattered at row completely
Hot tank, causes the existing original heat eliminating medium of the heat eliminating medium in transformer tank body to have new heat eliminating medium again, eventually results in
Radiating effect is not good in whole heat radiation box；The transformer radiator structure is when changing heat eliminating medium, if by original radiating
Medium is all discharged, and that will take considerable time, and when discharging original heat eliminating medium, the heat eliminating medium newly injected also may be used
The radiating of heart injection because the reasons such as good fluidity and original heat eliminating medium are admixed together and discharge, can be so caused to be situated between
The waste of matter.
