Abstract
The utility model belongs to the technical field of transformers, in particular to an implement-body oil-way structure of forcing oil circulation of an oil-immersed type electric power transformer. The implement-body oil-way structure of forcing oil circulation comprises an oil guiding pipe, a supporting board and a yoke insulated component on the supporting board, and the supporting board is provided with an oil path slot which is communicated with the oil guiding pipe. The utility model can make the oil path smoother with easy processing, which can effectively reduce the entire height of the transformer.
Description
Technical field
The utility model belongs to the transformer technology field, is specifically related to a kind of device body oil channel structures of forced oil-circulation of oil-immersed power transformer.
Background technology
At present, the device body oil channel structures of forced oil-circulation transformer generally as shown in Figure 1, 2, 3, adopt oil guide pipe 1 that oil is introduced the transformer body bottom, utilize the gap distribution oil stream of the Oil Guide cushion block 5 of core insulation spare 4 then, wherein core insulation spare 4 is formed by bonding benefit sticky pad piece 11, cushion block 10, Oil Guide cushion block 5 by a plurality of insulated rings 9, below insulated ring 9 is cushion block 10, insulated ring 9 tops be Oil Guide cushion block 5, the shape of Oil Guide cushion block 5 as shown in Figure 3, oil flows along radial and Oil Guide cushion block breach direction, so breach will be opened than higher.Insulation distance between the loop, the distance of coil reactance bottom window under the iron core than the big 20～30mm of permissible value about, this just increases the transformer whole height, increased cost, and the transformer oil that imports, entered and shunted again after Oil Guide on the transformer Oil Guide cushion block 5 lacks, there is the too high problem of local velocity in the flowability that has because of shunting inequality, and Oil Guide cushion block 5 structure more complicated are difficult to manual production, and production efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model is the above-mentioned defective at prior art, provides a kind of and can make that oil circuit is more unimpeded and easy to process, the device body oil channel structures of the forced oil-circulation that can reduce transformer height degree.
The technical scheme that solution the utility model technical problem is adopted is that the device body oil channel structures of this forced oil-circulation comprises the core insulation spare on oil guide pipe, supporting plate, the supporting plate, has the oil circuit groove on the supporting plate, and the oil circuit groove communicates with oil guide pipe.Core insulation spare is conjuncted core insulation spare, by three with one heart but different insulated ring and the cushion blocks of diameter be connected as a single entity.
The utility model is on original insulating part structure, utilize insulation machining center lathe on the monoblock supporting plate, to open the oil circuit groove, replace the Oil Guide on the Oil Guide cushion block to lack, deducted the Oil Guide cushion block, reduced this part height, oil circuit is more reasonable simultaneously, solves the defective of oily distributions inequality, reduce technology difficulty simultaneously, reduced the transformer cost.
The utility model is specially adapted to the oversize transformer that electric pressure is relatively low, capacity is higher relatively.
