Abstract
The utility model relates to an interwound type winding structure for a tapping area. The interwound type winding structure comprises a plurality of tapping sections. Each tapping section is wound by leads, oilways are arranged among the tapping sections, and adjacent taping sections are connected via leads, and three tapping joints are arranged between each two tapping sections. Ampere turns of a transformer winding are more uniform and balanced in distribution, anti-short circuit mechanical strength of the winding is effectively enhanced, magnetism leakage can be reduced, and anti-short circuit capability can be improved.
Description
Technical field
The utility model relates to a kind of tap region winding structure, belongs to transformer parts technical field.
Background technology
At present, the Transformer Winding of band tap region, the distributed pole of its ampere-turn is inhomogeneous.When ampere-turn distributes when more uneven, then laterally leakage field is serious more, and eddy current loss will increase with horizontal leakage reactance thereupon, produce bigger short circuit mechanical force, make lead between the coil cushion block towards axial bending, and high-power transformer will produce local overheating.The coil normal reach of existing band tap and tap section all adopt continous way (taking out 3 taps for 4 sections) and wire gauge identical; Tap section zone axial height is higher relatively; The axial height large percentage; Therefore the corresponding zone of low-voltage coil often will be highly corresponding with it through methods such as increasing oil ducts, and economy reduces.
The utility model content
The technical problem that the utility model will solve is, proposes a kind of Transformer Winding ampere-turn more uniform balance that distributes that makes, and can effectively strengthen winding Short Circuit withstand mechanical strength, reduces a kind of tap region that leakage field improves anti-short circuit capability simultaneously and is entangled with the formula winding structure.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of tap region is entangled with the formula winding structure; Comprise a plurality of tap sections; Each tap section is the lead coiling; Be provided with oil duct between the said tap section, and connect through lead between the tap section adjacent one another are, and be provided with three taps between per two tap sections.
Preferably: the width of the lead on the said tap section is less than the width of normal reach lead, and thickness is greater than the thickness of normal reach lead.
Preferred again: the width of the lead on the said tap section is b, and thickness is a, and the value of said b/a is between 2 to 3.
Preferred more again: said circle of being entangled with transposition insulate.
The tap region of the utility model is entangled with the formula winding structure, compares prior art, has following beneficial effect: because tap region adopts 2 sections technical schemes of taking out 3 taps of the formula of being entangled with; Therefore reduced tap section axial height, the low-voltage coil of corresponding tap circle need not amplify oil duct, improves the packing space of winding; Satisfy the requirement of drawing of winding tap, thereby can make the Transformer Winding ampere-turn more uniform balance that distributes, can effectively strengthen winding Short Circuit withstand mechanical strength; Reduce leakage field simultaneously and improve anti-short circuit capability; Thereby increased the reliability of transformer safe operation, improved the activity coefficient of winding, economy further improves.And because the width of the lead on the tap section is less than the width of normal reach lead, therefore thickness not only can improve the axis of winding stressing conditions greater than the thickness of normal reach lead; And winding process is better; And the width of the lead on the tap section is b, and thickness is a, and the value of said b/a is between 2 to 3; Therefore not only can improve the axis of winding stressing conditions, and winding process is better.Insulate the tolerance of climbing lead when therefore improving the product operation owing to be entangled with the circle of transposition.
Description of drawings
Fig. 1 is the structural representation that tap region is entangled with the formula winding structure;
Wherein: 1-switch, the 2-first tap section, the 3-second tap section, 4-oil duct, 5-first tap, 6-second tap, 7-the 3rd tap, 8-lead.
Embodiment
Accompanying drawing discloses the structural representation of a preferred embodiment of the invention without limitation, below will combine accompanying drawing that technical scheme of the present invention at length is described.
Embodiment
It is as shown in Figure 1 that the tap region of present embodiment is entangled with the formula winding structure, comprises the first tap section, 2, the second tap sections 3; And switch 1, each tap section is the lead coiling, is provided with oil duct 4 between the said first tap section 2 and the second tap section 3; Be connected by lead 8 between the said first tap section 2 and the second tap section 3, be provided with three taps between the said first tap section 2 and the second tap section 3, these three taps are respectively first taps 5; Second tap, 6, the three taps 7.
When said structure was applied to a plurality of tap section, each tap section was the lead coiling, is provided with oil duct between the said tap section, and connected through lead between the tap section adjacent one another are, and was provided with three taps between per two tap sections.
In order to improve the axis of winding stressing conditions, and winding process is better: the width of the lead on the said tap section is less than the width of normal tap section lead, and thickness is greater than the thickness of normal tap section lead.
In order to improve the axis of winding stressing conditions, and winding process is better: the width of the lead on the said tap section is b, and thickness is a, and the value of said b/a is between 2 to 3.
Climbing lead tolerance when moving in order to improve product: said circle of being entangled with transposition insulate.
Combine the preferred specific embodiment of the described the present invention of accompanying drawing only to be used to explain execution mode of the present invention above; Rather than as restriction to aforementioned goal of the invention and accompanying claims content and scope; Every foundation technical spirit of the present invention all still belongs to the present invention's technology and rights protection category to any simple modification, equivalent variations and modification that above embodiment did.
