Abstract
The utility model discloses an oil -immersed transformer high pressure laminar winding end coils adopts hem formula end coils structure, including cable paper (2), and this cable paper (2) upper portion forms cable paper folded portion (3) after folding. The utility model discloses a coil side separator hem machinery is with direct cable paper (2) hem for the thickness and the former end coils thickness of cable paper folded portion (3) are unanimous, have not only improved work efficiency, have still reduced material cost.
Description
Technical field
The utility model relates to a kind of oil-filled transformer high voltage layer type winding terminal circle, belongs to transformer technology field.
Background technology
Transformer is the major equipment in power transmission and transformation system, it is possible to a kind of voltage of alternating current, alternating current are converted to another kind of voltage of alternating current of same frequency and the electric energy of alternating current, mainly comprises dry type transformer and oil-filled transformer two kinds of forms. Wherein, oil-filled transformer forms primarily of iron core, winding, fuel tank, conservator, insulation thimble, tap switch and gas rly. etc., and the coil of transformer and magnetic core are immersed in inside special transformer oil, such benefit is, not only can dispel the heat but also coil and air can be made to completely cut off prevents the moisture in air from the magnetic core of transformer is caused corrosion, it is also possible to play certain arc extinguishing effect.
At present, 10KV oil-filled transformer high pressure winding adopts adhered end coil structures usually, by insulating board and cable paper as solid insulating material, by first cutting out paperboard strip (1) with sheet shears, by electrician's white glue with vinyl, paperboard strip (1) is bonded on the cable paper (2) of 0.08 again to be made, as depicted in figs. 1 and 2. But, this adhered end coil structures is in the process of coiling winding, it is necessary to one by one be placed on winding end, expend the time and efforts that staff is a large amount of, not only cause the inefficiency of the course of processing, but also waste work material, it is to increase production cost. A kind of oil-filled transformer layer formula winding with Novel end coil structures is developed so needing badly.
Summary of the invention
For above-mentioned existing technical problem, the utility model provides a kind of oil-filled transformer high voltage layer type winding terminal circle, to reduce manpower and materials, it is to increase production efficiency.
For achieving the above object, the utility model provides a kind of oil-filled transformer high voltage layer type winding terminal circle, comprise and adopt fold type end coil structures, comprise cable paper, and this cable paper top forms cable paper folded part after folding, and the thickness of this cable paper folded part is the thickness of end coil structures.
The utility model is mechanical by direct for cable paper flanging by layer insulation flanging, the thickness of the cardboard that the thickness of this cable paper folded part and former adhered end coil structures adopt is consistent, thus eliminate in original adhered end coil structures course of processing cut out, bonding operation. Not only make the course of processing more simple and convenient, it is to increase the working efficiency of staff; Also a saving the material of production simultaneously, eliminate the application of sheet shears, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of oil-filled transformer high voltage layer type winding in prior art;
Fig. 2 is the structural representation of adhered end circle in Fig. 1;
Fig. 3 is schematic diagram of the present utility model;
In figure: 1, cardboard, 2, cable paper, 3, cable paper folded part.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 3, the adhered end coil structures that the utility model is different from the past, but adopt fold type end coil structures. When specifically implementing, cable paper 2 top is directly folded into cable paper folded part 2, namely remains cable paper 1 part of former end circle shown in Fig. 2, replace paper slip 1 part with cable paper folded part 2, eliminate cutting out and bonding technique paper slip 1.
Further, for ensure this fold type end coil structures can normal operation, do not change the thickness of end coil structures, it is desired to the thickness of cable paper folded part 2 and paper slip 1 consistency of thickness of former end circle, so can according to thickness determine cable paper 2 need which floor folds out.
After enforcement, in the coiling operation of oil-filled transformer high voltage layer type winding, eliminate the material of paper slip 1, and the application of sheet shears, thus simplify the Making programme of workman, decrease the cost of material, it is to increase working efficiency.
Claims (2)
1. an oil-filled transformer high voltage layer type winding terminal circle, it is characterised in that, adopt fold type end coil structures, comprise cable paper (2), and this cable paper (2) top forms cable paper folded part (3) after folding.
2. a kind of oil-filled transformer high voltage layer type winding terminal circle according to claim 1, it is characterised in that, the thickness of described cable paper folded part (3) is the thickness of end coil structures.
