Abstract

The utility model discloses the energy-saving casing of a kind of oil immersed power transformer, comprise case body, described case body internal fixtion has magnetic screen framework, described magnetic screen framework is made up of the upper and lower framework for supporting transformer yoke and the multiple risers be fixedly connected between described upper and lower framework, and the lateral surface of described magnetic screen framework and the madial wall of case body fit; Described riser and upper and lower framework are by multilayer high-quality silicon steel sheet or multilayer Fe-based amorphous alloy plate is stacked forms; described every layer of high-quality silicon steel sheet or Fe-based amorphous alloy plate surface are coated with insulating oxide, are coated with epoxy resin protective layer at magnetic screen frame outer surface.The utility model advantage is that magnetic screen framework uses high-quality silicon steel sheet that transformer noload losses can be made to reduce between 5% ~ 8%, transformer noload losses can be made to reduce between 6% ~ 10% as adopted the material of Fe-based amorphous band class.

Description

The energy-saving casing of oil immersed power transformer
Technical field
The utility model relates to oil immersed power transformer, especially relates to the energy-saving casing of oil immersed power transformer.
Technical background
Oil immersed power transformer is widely used in the places such as power plant, transformer station, industrial and mining enterprises, business and residential quarter.The structure therein that manufactured and designed of oil-immersed type transformer takes multiple conservation measures, but the eddy current loss that oil immersed power transformer iron core leakage field is produced on its housing is but ignored by people.The yoke of oil immersed power transformer plays closed magnetic circuit effect, during transformer work all there is leakage field in upper and lower yoke, this part leakage field produces eddy current by the transformer case made at cold-rolled steel sheet (casing), especially shell (side box plate) part between upper and lower yoke forms strong vortex, and the part beyond between upper and lower yoke forms weak vortex.Because oil immersed power transformer usage quantity is very huge, the electric energy loss therefore reducing the strong vortex of oil immersed power transformer casing will be the key reducing electric energy loss further.
Summary of the invention
The utility model object is to provide a kind of oil immersed power transformer energy-saving casing, there is eddy current and energy loss to reduce oil immersed power transformer its casing under charging operation state.
For achieving the above object, the utility model takes following technical proposals:
The energy-saving casing of oil immersed power transformer described in the utility model, comprise case body, described case body internal fixtion has magnetic screen framework, described magnetic screen framework is made up of the upper and lower framework for supporting transformer yoke and the multiple risers be fixedly connected between described upper and lower framework, and the lateral surface of described magnetic screen framework and the madial wall of case body fit; Described riser and upper and lower framework are by multilayer high-quality silicon steel sheet or multilayer Fe-based amorphous alloy plate is stacked forms; described every layer of high-quality silicon steel sheet or Fe-based amorphous alloy plate surface are coated with insulating oxide, are coated with epoxy resin protective layer at magnetic screen frame outer surface.
The utility model advantage is, on the basis not changing existing oil immersed power transformer casing, to insert described magnetic screen framework in casing.When oil immersed power transformer charging operation, the leakage field that transformer upper magnet yoke and lower yoke produce no longer forms closed magnetic loop by transformer case, but form closed magnetic loop by magnetic screen framework, the material of magnetic screen framework presents high permeability, high resistivity characteristic, decreases oil immersed power transformer at the eddy current of its casing of charging operation state and energy loss.Magnetic screen framework uses high-quality silicon steel sheet that transformer noload losses can be made to reduce between 5% ~ 8%, transformer noload losses can be made to reduce between 6% ~ 10% as adopted the material of Fe-based amorphous band class.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of magnetic screen framework described in the utility model.
Fig. 3 is that the A-A of Fig. 2 is to profile.
Fig. 4 is the state reference map after the utility model installs transformer.
Embodiment
As Figure 1-4, the energy-saving casing of oil immersed power transformer described in the utility model, comprise case body 1, described case body 1 internal fixtion has magnetic screen framework, described magnetic screen framework is made up of the upper and lower framework 4,5 for supporting transformer upper magnet yoke 2 and lower yoke 3 and the multiple risers 6 be fixedly connected between described upper and lower framework 4,5, and the lateral surface of described magnetic screen framework and the madial wall of case body 1 fit; Described riser 6 and upper and lower framework 4,5 are by multilayer high-quality silicon steel sheet or Fe-based amorphous alloy plate 7 is stacked forms, and described every layer of Fe-based amorphous alloy plate 7 surface is coated with insulating oxide, is coated with epoxy resin protective layer 8 at the outer surface of magnetic screen framework.
