Further, described a kind of traction transformer of locomotive lead-in wire supportive device adapts near Transformer Winding one side and Transformer Winding peripheral shape.
Corresponding with described a kind of traction transformer of locomotive lead-in wire supportive device, the invention allows for a kind of traction transformer of locomotive lead-in wire support method, it is characterized in that: drawing the identical half slot of screw diameter by being symmetrical arranged respectively diameter on supporter one and the main supporter that supporter two consists of with the traction transformer iron core; Half slot by separately clamps and draws screw rod respectively with described supporter one and supporter two; Again two supporters are fixed on and draw on the screw rod; The traction transformer lead-in wire is supported by described supporter.
Further, described a kind of traction transformer of locomotive lead-in wire support method also is included on the above-mentioned main supporter basis and installs auxiliary supporter additional.
Further, described a kind of traction transformer of locomotive lead-in wire support method arranges installing hole at above-mentioned supporter, each supporter is fixed together with thread connecting mode by installing hole, and the lead-in wire of the different trends of traction transformer of locomotive is supported.
Further, described a kind of traction transformer of locomotive lead-in wire support method arranges lead-in wire by the hole at above-mentioned main supporter and auxiliary supporter, and the shape size in hole is according to the shape size setting in transformer lead cross section.
Further, described a kind of traction transformer of locomotive lead-in wire support method, described supporter is processed into the shape that adapts with the Transformer Winding peripheral shape near Transformer Winding one side.
Transformer or reactor body are by drawing screw rod tension folder from top to bottom unshakable in one's determination to be able to fastening, principle of the present invention is the lead-in wire supportive device to be fixed on draw on the screw rod, to draw screw rod as support, main supporter and auxiliary supporter are suited measures to local conditions crisscross, consist of the lead-in wire supportive device of transformer.The beneficial effect of the traction transformer lead-in wire supportive device that the present invention proposes and corresponding lead-in wire support method mainly is:
1) the lead-in wire supportive device is to draw screw rod to consist of main supportive device as supporting, the mode that employing is threaded is fixed, has easy accessibility, the characteristics of highly versatile, adopt the multiple supporter of certain specification between the transformer of different model, all can mutually use, not only reduce the design amount of publishing picture, product design and manufacturing standard and standardization level are improved.
2) the direct anchor leg of main support, other auxiliary supporter also can be installed on main supporter again, be connected and fixed with high-intensity bolt between supporter and the supporter, with the fixing arbitrarily lead-in wire of trend, mutually involve between each supporter, restriction is crisscross mutually, be difficult for upset, thereby form a firm lead line supporting structure.
3) the supportive device mechanical strength that consists of like this is large, and the operative employee can select correct position, stands in the work such as the connection of finishing lead-in wire on the lead line supporting structure and making, and construction operation is very convenient.
4) in addition, the close side of lead-in wire supportive device and Transformer Winding is processed into the inclined plane shape with its adaptation, in the operational environment of vibration Transformer Winding is played certain protective effect.

Embodiment
The present invention is further described below in conjunction with the drawings and specific embodiments.
The structural representation of the main supporter of the traction transformer lead-in wire supportive device that proposes of the present invention as shown in Figure 1.The supporter 1 and the supporter 22 that consist of main supporter use in pairs, and two adjacent bilateral symmetry of supporter offer semi-circular groove, and the screw diameter that draws of the diameter of groove and stationary transformer iron core is consistent, and two semi-circular groove form draws screw rod to pass through hole 3.Supporter 1 and supporter 22 are clamped by half slot separately and are drawn screw rod, be provided with holding screw hole 4 on it, with high-intensity bakelite bolted, it firmly is fixed in draws on the screw rod, can avoid support along the rotation of drawing screw rod center of circle direction with along drawing sliding up and down of spiro rod length direction.
Simultaneously, offer transformer lead on supporter one and the supporter 22 by hole 5, the position in these holes, size and shape determine that according to actual needs the concrete condition that goes between with traction transformer adapts.Certainly circle, the square lead-in wire illustrated among Fig. 1 only play the signal effect by the hole, can flexible configuration in the practical application.
Except the agent structure of the present invention shown in the embodiment 1, the following examples 22,3,4 provide further specifying of the present invention program by reference to the accompanying drawings, in order to preferably implement the present invention.
As shown in Figure 2, traction transformer lead-in wire supportive device master supporter of the present invention is anchor leg directly, but can also install auxiliary supporter 8 additional.Main supporter is fixed on the traction transformer iron core and draws on the screw rod 6, on main supporter and auxiliary supporter 8 installing hole 7 is set respectively, by high strength bakelite bolt each supporter is fixed together.Also the supporter of other directions can be installed in the same way again on the supporter, each supporter transverse and longitudinal is staggered, has satisfied the requirement of traction transformer lead-in wire any direction trend.The mutual weave in of each supporter checks and balance simultaneously, forms the rock-steady structure that mechanical strength is high.This stable structure is so that operating personnel can select safely the suitable station construction operations such as connection that go between at leisure.
In addition, consider that general Transformer Winding external diameter is for circular, the traction transformer iron core draws screw rod 6 very near with the distance of Transformer Winding 9 peripheries, the vibration of locomotive causes the transformer vibration and lead-in wire supportive device and winding is bumped in the use procedure, as shown in Figure 3 and Figure 4, the lead-in wire supportive device is designed to the inclined-plane that adapts with the winding peripheral shape near the winding side, and the gradient on inclined-plane and length are decided according to the winding peripheral shape.This ramp structure can guarantee that supportive device has enough mechanical strengths, can avoid again bumping with winding and the loosening and destroyed problem of winding surface insulation of supporter that occurs.
The present embodiment purpose is to make this area professional and technical personnel to understand technical scheme of the present invention according to it and is also implemented; can not limit with it protection range of this patent; allly disclose any distortion and the retouching that technology is done according to the present invention, all fall into protection scope of the present invention.
