Description
Technical field
The present invention relates 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 the place such as local lighting, skyscraper, airport, 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 are provided with spaced fin, and transformer radiator is as in the heat dissipation tank full of heat eliminating medium

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, is used
Heat eliminating medium afterwards can not recycle, and cause the wasting of resources；The transformer radiator structure is to pass through when changing heat eliminating medium
New heat eliminating medium is injected in heat eliminating medium outlet 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 dissipate without completely at row
Hot tank, cause the existing original heat eliminating medium of the heat eliminating medium in transformer tank body to have new heat eliminating medium again, eventually result in
Radiating effect is bad 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 be taken considerable time, and when discharging original heat eliminating medium, the heat eliminating medium newly injected also may be used
Energy can be admixed together with original heat eliminating medium because of reasons such as good fluidities and discharged, and the radiating that can so cause the heart to inject is situated between
The waste of matter.
