Abstract
A kind of strong oil not Directed cooling transformer of the utility model, is comprised the cooler and oil tank of transformer that are connected by circulating oil path, and is arranged on the coil device body in oil tank of transformer; Circulating oil path is in oil tank of transformer inner and oil circuit beyond coil device body coil is provided with insulation stop oiled-plate method, insulation stop oiled-plate method connects with the inner wall sealing of the coil outer wall contacted and oil tank of transformer respectively; The position of insulation stop oiled-plate method is higher than the oil-in position of oil tank of transformer on circulating oil path.By the setting at insulation stop oiled-plate method, the oil circuit of coil outer is carried out to control and the change of oily flow path, cold oil must be circulated by being formed after coil inside, thus avoid by the bypass of coil outer oil duct, reduce temperature rise in coil, ensure that the inside and outside uniform product temperature rise of coil device body, do not change the existing structure of existing product, with low cost, applied widely; Even if still there is extraordinary Natural Oil Circulation Power cooling effect when oil pump does not start.
Description
Technical field
The utility model relates to transformer manufacture technology, is specially a kind of strong oil not Directed cooling transformer.
Background technology
Along with the increase of transformer capacity, effective material that unit capacity consumes reduces, the loss also corresponding minimizing of unit capacity, and maintenance work also can reduce, and therefore transformer is all developing to Large Copacity at present, and this just will inevitably bring the problem of cooling.Reasonable mode is the type of cooling adopting the inner forced-directed oil cooling of winding, to ensure winding internal temperature rise.Another kind of mode oily is by force that strong oil does not lead, just forced oil-circulation, the mode of the inner not Directed cooling of winding, and owing to not leading, the temperature rise control difficulty of this mode transformer coil is larger; Existing strong oil is not under Directed cooling mode, because the resistance of fuel tank internal oil is much smaller than the resistance of coil inside oil, a large amount of transformer oil is bypassed at fuel tank internal, coil inside remains naturally oil circulation, flow velocity is very low, and flow is very little, and the oil temperature of the temperature rise ratio fuel tank internal of coil inside is high a lot, and the cold oil in fuel tank does not act on control coil temperature rise, cause very large waste; Strengthen oil duct if simple or reduce the modes such as electricity is close and realize lowering the temperature and not only change the structure of original transformer, and the financial burden of manufacturing cost and operation can be increased.
Utility model content
For problems of the prior art, the utility model provide a kind of ensure coil inside and outside temperature rise identical, the significant strong oil not Directed cooling transformer of cooling-down effect.
The utility model is achieved through the following technical solutions:
Strong oil not Directed cooling transformer comprises the cooler and an oil tank of transformer that are connected by circulating oil path, and is arranged on the coil device body in oil tank of transformer; Described circulating oil path is in oil tank of transformer inner and oil circuit beyond coil device body coil is provided with insulation stop oiled-plate method, insulation stop oiled-plate method connects with the inner wall sealing of the coil outer wall contacted and oil tank of transformer respectively; The position of insulation stop oiled-plate method is higher than the oil-in position of oil tank of transformer on circulating oil path.
Preferably, insulation stop oiled-plate method is integrated setting, and sealing shroud is located on the coil in coil device body.
Further, insulation stop oiled-plate method is arranged on the bottom of coil device body.
Further, insulation stop oiled-plate method adopts insulating board to make.
Further again, insulation stop oiled-plate method is fixedly connected with the lower yoke insulating board of transformer or in being wholely set.
Compared with prior art, the utility model has following useful technique effect:
The utility model is by the setting at insulation stop oiled-plate method, the oil circuit of coil outer is carried out to control and the change of oily flow path, cold oil must be circulated by being formed after coil inside, thus avoid by the bypass of coil outer oil duct, thus reduce temperature rise in coil, ensure that the inside and outside uniform product temperature rise of coil device body, and do not change the existing structure of existing product, good cooling results, with low cost, applied widely; Even if still there is extraordinary Natural Oil Circulation Power cooling effect when oil pump does not start.
Further, by the setting of integration, ensure that structural strength and the excellent gear oil effect of insulation stop oiled-plate method, utilize with the sealing of coil device body sheathed, conveniently achieve the change to oil circuit, and be fixedly connected with mode without the need to other, reasonable in design, structure is simple.
Further, by the restriction to insulation stop oiled-plate method position, can ensure that more cold oil directly can enter coil inside, utilize and also better processing is simplified to the restriction of material, reduce cost.
Accompanying drawing explanation

Fig. 2 is the front view of insulation stop oiled-plate method 4 in Fig. 1.
Wherein: 1 is cooler; 2 is oil tank of transformer; 3 is coil device body; 4 is insulation stop oiled-plate method; 5 is cooling blower; 6 is oil pump.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of strong oil not Directed cooling transformer of the utility model, as shown in Figure 1, is comprised the cooler 1 and oil tank of transformer 2 that are connected by circulating oil path, and is arranged on the coil device body 3 in oil tank of transformer 2; Circulating oil path is in oil tank of transformer 2 inner and oil circuit beyond coil device body 3 coil is provided with insulation stop oiled-plate method 4, insulation stop oiled-plate method 4 connects with the inner wall sealing of the coil outer wall contacted and oil tank of transformer 2 respectively; The position of insulation stop oiled-plate method 4 is higher than the oil-in position of oil tank of transformer on circulating oil path 2.By to coil outer, the block of oil tank of transformer 2 internal oil passages, adds the oil resistance of oil tank of transformer 2 inside, makes a large amount of cold oil enter coil inside, greatly reduce the temperature rise of winding; Thus can adopt less horizontal oil duct when ensureing same temperature rise, compared with the cooler 1 of small dimension, substantially reduce transformer cost, decrease cost of floor space, be very beneficial for design of transformer.
In this preferred embodiment, as depicted in figs. 1 and 2, insulation stop oiled-plate method 4 is in integrated setting, and sealing shroud is located on the coil in coil device body 3; Insulation stop oiled-plate method 4 is arranged on the bottom of coil device body 3 and adopts insulating board to make with insulation stop oiled-plate method 4.In this preferred embodiment, three coils are included in coil device body 3, independent making insulation stop oiled-plate method 4 is fixed on lower yoke insulating board, or with lower yoke insulating board in being wholely set, namely say that lower yoke insulating board directly amplifies the inwall place extending to oil tank of transformer 2, and play reinforcement fixation by lower yoke cushion block, bear long-term oily stream to wash away and not yielding, ensure result of use, thus directly can cut off the flowing of cold oil in oil tank of transformer 2, make cold oil can only be inner by the in-line footpath inflow line circle of coil, thus add the oil stream of coil inside, play good cooling effect, all electric pressure transformers can be applicable to, be particularly useful for all kinds of products with larger capacity.
