Corresponding to described a kind of traction transformer of locomotive supportive device that goes between, the invention allows for a kind of traction transformer of locomotive lead-in wire support method, it is characterized in that: on the main supporter be made up of with supporter two supporter one, be symmetrical arranged the half slot that diameter draws screw diameter identical with traction transformer iron core respectively; Described supporter one and supporter two are clamped respectively by respective half slot and draws screw rod; Being fixed on by two supporters draws on screw rod again; Traction transformer lead-in wire is supported by described supporter.
Further, a kind of described traction transformer of locomotive lead-in wire support method is also included on above-mentioned main supporter basis and installs auxiliary supporter additional.
Further, a kind of described traction transformer of locomotive lead-in wire support method, above-mentioned supporter is arranged installing hole, is fixed together by each supporter by installing hole thread connecting mode, support the lead-in wire of traction transformer of locomotive difference trend.
Further, a kind of described traction transformer of locomotive lead-in wire support method, above-mentioned main supporter and auxiliary supporter arrange lead-in wire passing hole, and the shape size in hole is arranged according to the shape size in transformer lead cross section.
Further, a kind of described traction transformer of locomotive lead-in wire support method, described supporter is processed into the shape adapted with Transformer Winding peripheral shape near Transformer Winding side.
Transformer or reactor body fastening by drawing the folder from top to bottom of tie-rod iron core to be able to, principle of the present invention is fixed on by lead-in wire supportive device to draw on screw rod, to draw screw rod for supporting, main supporter and auxiliary supporter are suited measures to local conditions crisscross, form 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 is mainly:
1) supportive device that goes between is formed main supportive device to draw screw rod for supporting, the mode be threaded is adopted to fix, there is easy accessibility, the feature of highly versatile, the multiple supporter of certain specification is adopted all can mutually to use between the transformer of different model, not only reduce the design amount of publishing picture, also make product design and manufacturing standard and standardization level improve simultaneously.
2) main support can direct anchor leg, other auxiliary supporter also can be installed on main supporter again, be connected and fixed with the bolt of high strength between supporter and supporter, with the lead-in wire of fixing trend arbitrarily, mutually involve between each supporter, mutually limit, crisscross, not easily overturn, thus the lead line supporting structure that formation one is firm.
3) the supportive device mechanical strength formed like this is large, and operative employee can select correct position, and stand in the work such as the connection that lead line supporting structure completes lead-in wire and making, construction operation is very convenient.
4) in addition, lead-in wire supportive device and Transformer Winding are processed into the inclined plane shape with its adaptation near side, in the operational environment of vibration, play certain protective effect to Transformer Winding.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Embodiment 1
The structural representation of the main supporter of the traction transformer lead-in wire supportive device of the present invention's proposition as shown in figure 1.The supporter 1 and the supporter 22 that form main supporter use in pairs, and two adjacent bilateral symmetry of supporter offer semi-circular groove, and the diameter of groove and the screw diameter that draws of stationary transformer iron core are consistent, and two semi-circular groove are formed draws screw rod passing hole 3.Supporter 1 and supporter 22 are clamped by respective half slot and are drawn screw rod, be provided with holding screw hole 4, by the bakelite bolted of high strength, it being firmly fixed on and drawing on screw rod, support can being avoided to draw sliding up and down of spiro rod length direction along drawing the rotation in direction, the screw rod center of circle and edge.
Meanwhile, supporter one and supporter 22 offer transformer lead passing hole 5, position, the size and shape of this some holes are determined according to actual needs, and the concrete condition gone between with traction transformer adapts.The circle illustrated in certain Fig. 1, square lead-in wire passing hole only play signal effect, can flexible configuration in practical application.
Embodiment 2
Except the agent structure of the present invention shown in embodiment 1, the following examples 22,3,4 provide further illustrating of the present invention program by reference to the accompanying drawings, preferably to implement the present invention.
As shown in Figure 2, the main supporter of traction transformer of the present invention lead-in wire supportive device can direct anchor leg, but can also install auxiliary supporter 8 additional.Main supporter is fixed on traction transformer iron core and draws on screw rod 6, and main supporter and auxiliary supporter 8 arrange installing hole 7 respectively, is fixed together by each supporter by high strength bakelite bolt.Supporter also can be installed in the same way again the supporter in other directions, each supporter transverse and longitudinal is interlocked, and meets 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 a mechanical strength is high.This stable structure makes operating personnel can select safely suitable station at leisure to carry out the construction operations such as lead-in wire connection.
In addition, consider that general Transformer Winding external diameter is for circular, traction transformer iron core draws screw rod 6 very near with the distance of Transformer Winding 9 periphery, in use procedure, the vibration of locomotive causes transformer vibrate and lead-in wire supportive device and winding are collided, as shown in Figure 3 and Figure 4, lead-in wire supportive device is designed to the inclined-plane adapted with winding peripheral shape near winding side, the gradient on inclined-plane and length are determined according to winding peripheral shape.This ramp structure can ensure that supportive device has enough mechanical strengths, can avoid again colliding with winding and the supporter that occurs loosens and the destroyed problem of winding surface insulation.
The present embodiment object is to make professional and technical personnel in the field understand technical scheme of the present invention according to it and to be implemented; the protection range of this patent can not be limited with it; allly disclose according to the present invention any distortion and retouching that technology does, all fall into protection scope of the present invention.
