Abstract
The invention relates to an external circulation bypass structure between converter transformer core pulling plate columns, in particular to a circulation bypass structure between large-capacity converter transformer core pulling plate columns, and belongs to the technical field of transformer manufacturing. According to the technical scheme, a plurality of copper cables (4) are arranged in a conductor grip frame (3), the copper cables are connected with coil outgoing wires and then connected with an upper clamp and a lower clamp, and the copper cables, the upper clamp, the lower clamp and core main column pulling plates form short circuit rings (2) along core windows. The external circulation bypass structure has the advantages that on the premise that the structure and the strength of the pulling plates are not changed, losses of the pulling plates are reduced, eddy current losses of cores are greatly reduced, leakage flux is restrained, the structure is simple, and layout is reasonable.
Description
Technical field
The present invention relates to a kind of external converter transformer iron core arm-tie intercolumniation circulation bypass structure, especially large capacity converter transformer arm-tie intercolumniation unshakable in one's determination circulation bypass structure, belongs to technical field of transformer manufacturing.
Background technology
For high-end large capacity converter transformer, all unavoidably there is an identical problem,, by pressure regulation winding tap lead leakage field, in iron core frame, produce induced current, powerful induced current will cause that arm-tie resistance loss sharply increases, and makes local overheating.
Summary of the invention
The object of the invention is to provide a kind of external converter transformer iron core arm-tie intercolumniation circulation bypass structure, and copper cable, folder from top to bottom and principal post arm-tie unshakable in one's determination form short-circuited conducting sleeve along window unshakable in one's determination, suppresses leakage field, solves the problem existing in background technology.
Technical scheme of the present invention is:
A kind of external converter transformer iron core arm-tie intercolumniation circulation bypass structure, arranges many copper cables in wire clamp framework, after copper cable is connected with coil outlet, connect folder from top to bottom, and copper cable, folder from top to bottom and principal post arm-tie unshakable in one's determination form short-circuited conducting sleeve along window unshakable in one's determination.
Described many copper cables are arranged side by side.
The invention has the beneficial effects as follows: not changing under the prerequisite of pulling plate structure and intensity, both reduced arm-tie loss, improved greatly the eddy current loss on final stage iron unshakable in one's determination, saved space simultaneously, simple in structure, rationally distributed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: principal post 1 unshakable in one's determination, short-circuited conducting sleeve 2, wire clamp framework 3, copper cable 4.
Embodiment
Below in conjunction with accompanying drawing, by example, the invention will be further described.
With reference to accompanying drawing 1, a kind of external converter transformer iron core arm-tie intercolumniation circulation bypass structure, many copper cables of the interior layout of wire clamp framework 34, connect folder from top to bottom after copper cable is connected with coil outlet, and copper cable, folder from top to bottom and principal post arm-tie unshakable in one's determination form short-circuited conducting sleeve 2 along window unshakable in one's determination.
Because converter transformer voltage regulation coil goes out line current, reach as high as amperes up to ten thousand, for avoiding the less return yoke arm-tie in cross section by electric current, return yoke arm-tie and folder from top to bottom are disconnected, and use outside copper cable to replace, form short-circuited conducting sleeve, prevent that leakage field is through in iron core.
Take with many copper cables, to be arranged side by side in wire clamp framework, short-circuited conducting sleeve with coil outlet, folder from top to bottom, principal post arm-tie unshakable in one's determination form, prevents that leakage field is through in iron core, simultaneously not to the iron core processing of slotting, grain orientation is complete, and the magnetic property of high performance silicon steel disc has obtained abundant application.
Claims (2)
1. an external converter transformer iron core arm-tie intercolumniation circulation bypass structure, it is characterized in that many copper cables of layout (4) in wire clamp framework (3), after copper cable is connected with coil outlet, connect folder from top to bottom, copper cable, folder from top to bottom and principal post arm-tie unshakable in one's determination form short-circuited conducting sleeve (2) along window unshakable in one's determination.
2. external converter transformer iron core arm-tie intercolumniation circulation bypass structure according to claim 1, is characterized in that described many copper cables are arranged side by side.
