Abstract
The invention discloses a longitudinal insulating structure of a high-voltage segmental layered coil of a casting dry type transformer, which consists of multiple sections of coil conducting wires which are arranged in the total height direction along a coil. Each section of coil conducting wire is formed by winding a plurality of layers of original conducting wires; and the two adjacent sections of coil conducting wires are formed by continuously winding the original conducting wire of which the beginning part and the end part are connected with each other. In the winding process of the coil of the invention, the fourth section and the eighth section of coil conducting wires are wound firstly, then the coil is turned around, and the third section, the second section, the first section, the seventh section, the sixth section and the fifth section of coil conducting wires are wound in sequence; because the end of the innermost layer of the original conducting wire of each section of the coil conducting wire is crossly connected with the end of the outermost layer of the original conducting wire of the coil conducting wire of the adjacent sections, the whole coil conducting wires only need to be broken for two times, and the times of welding the coil conducting wire wires are reduced. The maximum voltage between the points a and b is 1/2 of the voltage between the original points a and b, therefore, the intersegment distance L2 is theoretically half of L1 so as to reduce the height of the whole coil, reduce the height of magnet core windows and decrease the usage amount of iron cores.
Description
Technical field
The present invention relates to a kind of longitudinal insulating structure of high-voltage segmental layered coil of casting dry type transformer.
Background technology
As shown in accompanying drawing 1 and accompanying drawing 2, in the longitudinal insulating structure of high-voltage segmental layered coil of casting dry type transformer, distance L 1 between its each line segment depends on the maximum voltage between diagram a, the b at 2, winding process is earlier around 2,4,6,8 sections, coil tune is again around 1,3,5,7 section then, so the whole winding lead need disconnect and welds six times then.Cause transformer turn-to-turn and layer insulation to destroy easily because wire bonds is dealt with improperly, thereby therefore the potential safety hazard of staying require in the transformer coil wire bonds place number few more good more.
And, the intersegmental connected mode of this longitudinal insulating structure of the prior art is that the former line line end of the lead of innermost layer directly links to each other with the former line line end of the lead of the innermost layer of the winding wire of adjacent segment, therefore the distance L 1 between each line segment depends on the maximum voltage between diagram a, the b at 2, make coil height higher, the iron core large usage quantity.
Summary of the invention
The longitudinal insulating structure that the purpose of this invention is to provide a kind of high-voltage segmental layered coil of casting dry type transformer, it has reduced wire bonds number of times in the transformer coil, and can reduce the height of whole winding.
The present invention can be implemented by the following technical programs: a kind of longitudinal insulating structure of high-voltage segmental layered coil of casting dry type transformer, it is made up of the multistage winding wire that distributes along coil height overall direction, described every section winding wire is formed by the former wire-wound system of multi-layer conductor leads, and described adjacent two sections winding wires are formed by the continuous coiling of an end to end former line of lead.
Intersect with the former line line end of the outermost lead of the winding wire of adjacent segment along the above the former line line end of lead of innermost layer of every section winding wire of coil height overall direction from left to right and link to each other, be the same continuous coiling of lead.
Have a plurality of minutes wiring leading-out terminals on the described multistage winding wire, the multistage winding wire between described first and last head end and the branch wiring leading-out terminal is formed by a continuous lead that only has a plumb joint.
Compared with the prior art the present invention has following advantage:
Because the former line line end of lead of the innermost layer of every section winding wire intersects with the former line line end of the outermost lead of the winding wire of adjacent segment and links to each other, in the winding process of coil of the present invention, earlier around the 4th, the 8th section, the coil tune is more successively around the 3rd, 2,1 section and the 7th, 6,5 section then, the whole winding lead only need disconnect twice, has reduced the number of times of bonding wire.
And, compared with prior art the maximum voltage between 2 of a between adjacent segment, the b be between original a, b voltage 1/2, therefore intersegmental distance L 2 is half of L1 in theory, thereby line segment height overall H1 can reduce, make the whole winding height to reduce, window unshakable in one's determination is high to be reduced, and has significantly reduced the iron core consumption.

Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the invention are elaborated:
As accompanying drawing 3 to as shown in the accompanying drawing 6, a kind of longitudinal insulating structure of high-voltage segmental layered coil of casting dry type transformer, it is made up of 8 sections winding wires 1 that distribute along coil height overall direction, described every section winding wire 1 is formed by former line 2 coilings of 5 layer conductors, have layer insulation 6 between the former line 2 of every layer conductor, described adjacent two sections winding wires 1 are formed by the former line 2 continuous coilings of an end to end lead.
In detail, from left to right along on the coil height overall direction, former line 2 line ends of the lead of the innermost layer of described every section winding wire 1 intersect with former line 2 line ends of the outermost lead of the winding wire 1 of adjacent segment and link to each other, and promptly intersegmental line 5 is for intersecting the same lead that links to each other.
Have a plurality of minutes wiring leading-out terminals 3 on the described multistage winding wire 1, it is the terminal 2,3,4,5 in the accompanying drawing, described first and last head end 4, promptly the multistage winding wire 1 between terminal A, X and the branch wiring leading-out terminal 3 is formed by a former line 2 of continuous lead.
Be described in detail winding process below at coil of the present invention, at first around the 4th, the 8th section, the coil tune is more successively around the 3rd then, 2,1 section and the 7th, 6,5 sections, because former line 2 line ends of lead of the innermost layer of every section winding wire 1 intersect with the former 2 line line ends of the outermost lead of the winding wire 1 of adjacent segment and link to each other, compared with prior art, the whole winding lead only need disconnect twice, reduced the number of times of bonding wire, thereby avoided having strengthened the insulation safety of transformer greatly because wire bonds is dealt with the transformer turn-to-turn and the layer insulation destruction of causing easily improperly.
And, compared with prior art, maximum voltage between 2 of a among the present invention between adjacent segment, the b be between original a, b voltage 1/2, therefore intersegmental distance L 2 is half of L1 in theory, thereby line segment height overall H1 can reduce, make the whole winding height H to reduce, window unshakable in one's determination is high to be reduced, and has significantly reduced the iron core consumption.
