Affiliated technical field:
The utility model relates to a kind of ultra high voltage converter transformer three posts and the side outgoing line device of networking, and belongs to technical field of transformer manufacturing.
Background technology:
Net side lead-in wire is one of parts of most critical in the converter transformer, and the one end links to each other with the head end of net side winding, and the other end is connected with sleeve pipe.Because the restriction of transportation boundary and hauled weight and ultra high voltage grade, the ultra high voltage converter transformer three post parallel-connection structures that adopt more, this structure directly connects as adopting lead-in wire, because lead-in wire is thin and out-of-shape, cause the electric field distortion, part position possibility electric field is too high, causes transformer discharge even puncture.
The utility model content:
The utility model purpose provides a kind of ultra high voltage converter transformer three posts and the side outgoing line device of networking, and makes lead-in wire even, the increase product safety coefficient of electric field on every side, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is:
Ultra high voltage converter transformer three posts and the side outgoing line device of networking comprise three balance pipes that penetrate the winding outlet, are arranged on three voltage equalizing balls between the balance pipe, three balance pipes are respectively left side balance pipe, right side balance pipe, downside balance pipe, one end of three balance pipes is set in respectively in the voltage equalizing ball, and three balance pipes are connected with voltage equalizing ball by connector and securing member.
The utility model voltage equalizing ball is a cylinder that copper coin bends, and voltage equalizing ball has been installed with the insulation pulp layer outward, and voltage equalizing ball is sleeved in the insulating paper cylinder.
Balance pipe end, the utility model left side is provided with shading ring, and balance pipe is sleeved in the insulating paper cylinder, and the structure of right side balance pipe is identical with it.
The beneficial effects of the utility model are as follows: adopt split-type structural, mainly be divided into four parts: two ends and bottom are balance pipe, and the centre is a voltage equalizing ball; Be convenient to the to go between installation of connection and balance pipe, voltage equalizing ball of this structure; In order to improve the lead-in wire electrode shape, reduce electric field and concentrate, outside net side lead-in wire, installed balance pipe additional; Its effect is that electric field becomes comparatively even around making lead-in wire, increases coefficient of safety.Three post parallel-connection structure problems of ultra high voltage converter transformer net side winding have effectively been solved.
