Fig. 2 is the low voltage foil winding coil outlet schematic diagram of oil-filled transformer described in the utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect clearly and be easy to understand, below in conjunction with the drawings and specific embodiments, the utility model being further elaborated:
As shown in Figure 2, the utility model provides a kind of oil-filled transformer low voltage foil winding coil, comprise coil body 20, described coil body 20 is provided with low pressure head end outlet row 21 and low pressure end outlet row 22, described low pressure head end outlet row 21, low pressure end outlet row 22 are positioned at the same side of coil body 20 and are in the upper end of coil body 20, described low pressure head end outlet row 21 is arranged in line, and described low pressure end outlet row 22 is arranged to bending row.
In such scheme, the low pressure head end outlet row 21 of low voltage foil winding coil is made in line, enable it for directly drawing between the upper clamping piece and lamination of transformer during oil-filled transformer, and low pressure end outlet row 22 is arranged to bending row, enabling it for drawing between the upper clamping piece of transformer and coil body 20 during oil-filled transformer, therefore solving the problem of the low pressure first and end outlet copper bar outlet of low voltage foil winding coil very well.
Wherein, described low pressure head end outlet row 21, low pressure end outlet row 22 are copper bar.Simultaneously as such scheme one preferably embodiment be, described low pressure end outlet row 22 and low pressure head end outlet row 21 are all near a wherein end of coil body 20, and low pressure end outlet row 22 is outside, low pressure head end outlet row 21 interior, as seen from Figure 1.Wherein said low pressure end outlet row is less than 90 degree at the bending angle of bending place, namely be a kind of not exclusively vertical bending, this design can make can reserve enough large distance between oil-filled transformer upper clamping piece and coil body, adapts to the upper clamping piece that model is large.
On the basis of such scheme, the utility model additionally provides a kind of oil-filled transformer comprising above-mentioned low voltage foil winding coil, see Fig. 2, this oil-filled transformer also comprises iron core 24, clamp insulation 25, upper clamping piece 23, described iron core 24 is supported by upper clamping piece 23 with the coil body 20 of low voltage foil winding coil, and is provided with clamp insulation 25 between described upper clamping piece 23 and iron core 24; Wherein, the low pressure head end outlet row 21 of described low voltage foil winding coil is drawn straight from clamp insulation 25, the low pressure end outlet row 22 of described low voltage foil winding coil is drawn between upper clamping piece 23 and coil body 20, and the center line of described upper clamping piece 23 and the center line of iron core 24 overlap.
As can be seen here, have employed the low voltage foil winding coil that aforementioned schemes provides, make oil-filled transformer need not reduce the size model of upper clamping piece 23, employing should have the upper clamping piece of size, and the center line of upper clamping piece 23 and iron core 24 center line do not depart from, see Fig. 2, therefore well ensure that iron core 24 chuck strength, reduce transformer noise and no-load loss, simultaneously because one of them is in line and do not need bending, copper bar weight saving reduces cost.
Wherein, described upper clamping piece 23 is channel-section steel folder.It should be noted that Fig. 2 middle slot steel clamp part 23 is of a size of large model (should have model), and channel-section steel folder 13 size in Fig. 1 is ting model, Fig. 1-2 is also known in contrast.Fig. 1 adopts the channel-section steel folder 13 of ting model to be because the outlet copper bar set-up mode of low voltage foil winding coil limits to, and the utility model is by improving the outlet copper bar set-up mode of low voltage foil winding coil, make the model that should have of channel-section steel folder 23 not need to be replaced with ting model, therefore effectively ensure that iron core clamping degree.
