According to the low temperature rise dry-type transformer provided by the invention, flow of air is increased by adding the air flues; the coils are arranged into a progressive increase structure; and the wind direction guide device is added, so that the temperature rise of the coils is effectively lowered; and the heat generated by the transformer in the operation process is timely brought outside the transformer to achieve the cooling target.
Description
Technical field
The present invention relates to field transformer, particularly relate to a kind of low-temperature-rise dry-type transformer.
Background technology
Epoxy pouring type dry type variant distribution transformer can both meet the requirement of the energy-saving material-saving of current distribution system on stuctures and properties.Make comparisons with regard to the current transformer that can for select, the new change of epoxy pouring type dry type variant distribution transformer in operation and code have also been obtained the accreditation of more and more user.Due to open dry-type transformer structure existing, impact resistance is low, tolerance short-circuit strength is poor, moistureproof, anti-dust performance is poor and make the problems such as ageing of insulation because of corona discharge.And epoxy pouring type dry type piezoelectric transformer just eliminates the problems referred to above well; it has poured into a mould the special epoxy resin of transformer at the electromagnetic wire parcel of the good coil of coiling; ensure that electrical strength and the mechanical strength of coil, for coil and even transformer itself provides good protection.
But, because the special epoxy resin of transformer poured into a mould by the electromagnetic wire parcel at the good coil of coiling, coil is made to form a rigidity entirety, have impact on by the heat dispersion of molded coil, the convection current that the heat produced when transformer is normally run not readily passes through air distributes, cause the temperature rise of transformer more and more higher, accelerate the speed of ageing of insulation, substantially reduce the useful life that transformer is original.
