Description
Technical field
The utility model relates to transformer accessory technical field, especially a kind of high strength oil collecting pipe.
Background technique
When transformer runs, the heat that the loss in winding and iron core produces must be gone out in dissipation in time, in order to avoid overheated and cause insulation damages.To small capacity transformer, external surface area is relatively large with the ratio of transformer volume, can adopt self cooling mode, heat can be left by radiation and natural convection.Due to the loss of transformer and its volume proportional, so along with the increase of transformer capacity, its volume and loss will increase with core dimensions cube, and external surface area only increases according to the quadratic power of size.Therefore, high-power transformer iron core and winding should be immersed in oil, and take the cooling method of oil.Most distribution transformers and many power transformers are all adopted in this way.The transformer that capacity is less, smooth tank surface is just enough to by oil cooling but; Intermediate size transformer, tank surface will make wrinkle shape to increase heat dispersing surface, or installs chip or flat-tube radiator additional, and oil is circulated in radiator; High-power transformer tank surface should add radiator.
At the upper and lower part oil collecting pipe of high-power transformer gilled radiator, adopt Ф 89 pipe to make, transformer runs the deep fat of generation by dispelling the heat in each box sheet of the oil collecting pipe inflow radiator on gilled radiator top, and then is returned in transformer by cold oil by bottom oil collecting pipe.If when Ф 89 oil collecting pipe that this bore is less selects more than 20 box sheets with oil collecting pipe compounded plate, when its two ends box sheet centre distance is more than 2500mm, whole radiating fin physical dimension does not ensure designing requirement, namely the mechanical strength of pipe is inadequate, in oil collecting pipe, hot oil temperature is higher, very easily scorch other accessories around oil collecting pipe, affect the working life of transformer.
Model utility content
The technical problems to be solved in the utility model is: can not ensure greatly mechanical strength and the too high problem affecting other accessories working life of temperature of oil collecting pipe to provide a kind of high strength oil collecting pipe to solve existing transformer radiator oil collecting pipe because of opening density.
The utility model solves the technological scheme that its technical problem adopts: a kind of high strength oil collecting pipe, comprise body and the flanged plate being arranged on body two ends, described body side evenly has some slots, described body comprises the interior pipe, intervalve and the outer tube that arrange from inside to outside, the thin plate circle system that described intervalve is corrugated arrangement by cross section forms, the interior outside of described thin plate is all coated with glass fibre, and the two ends of described interior pipe, intervalve and outer tube are all fixed with flanged plate.
The beneficial effects of the utility model are, oil collecting pipe body side evenly has some slots to install radiating fin, because existing oil collecting pipe caliber is less, and slot is more, radiating fin physical dimension does not ensure designing requirement, the mechanical strength of oil collecting pipe is inadequate, intervalve and outer tube is increased outward at existing oil collecting pipe, the thin plate circle system that intervalve is corrugated arrangement by cross section forms, the interior outside of thin plate is all coated with glass fibre, quality is light, can not impact the radiating fin of support set oil pipe, the mechanical strength of oil collecting pipe can not only be ensured, also play heat insulation effect, extend the working life of transformer.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross section structure schematic diagram of the present utility model;
Fig. 3 is the inner section structural representation of the utility model intervalve.
In figure: 1. body, pipe in 11., 12. intervalves, 13. outer tubes, 14. thin plates, 15. glass fibres, 2. slot, 3. flanged plate.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Figure 1-3, a kind of high strength oil collecting pipe, comprise body 1 and the flanged plate 3 being arranged on body 1 two ends, described body 1 side evenly has some slots 2, described body 1 comprises the interior pipe 11, intervalve 12 and the outer tube 13 that arrange from inside to outside, thin plate 14 system of enclosing that described intervalve 12 is corrugated arrangement by cross section forms, and the interior outside of described thin plate 14 is all coated with glass fibre 15, and the two ends of described interior pipe 11, intervalve 12 and outer tube 13 are all fixed with flanged plate 3.
Oil collecting pipe body 1 side evenly has some slots 2 to install radiating fin, because existing oil collecting pipe caliber is less, and slot 2 is more, radiating fin physical dimension does not ensure designing requirement, the mechanical strength of oil collecting pipe is inadequate, the utility model increases intervalve 12 and outer tube 13 outward at existing oil collecting pipe, thin plate 14 system of enclosing that intervalve 12 is corrugated arrangement by cross section forms, the interior outside of thin plate 14 is all coated with glass fibre 15, quality is light, can not impact the radiating fin of support set oil pipe, the mechanical strength of oil collecting pipe can not only be ensured, also play heat insulation effect, extend the working life of transformer.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
