Abstract
The utility model relates to a wire-leading device which leads out the wire from the winding end and is provided with a single-phase double-terminal parallel structure and used for large-capacity high-voltage transformers. The wire-leading device comprises two balance pipes which penetrate the winding for wire-outgoing and two balance balls arranged between the two balance pipes; the two ends of the two balance pipes are respectively arranged inside the two balance balls in a penetrating way; the two balance pipes are connected with fastening parts arranged inside the balance balls by connecting parts. In order to improve the lead electrode form and reduce electric field concentration, the wire-leading device adds the balance pipes outside the high-voltage leads so as to cause the electric field surrounding the lead to become equal and enhance the safety; therefore, the problem of the double-terminal parallel wire-outgoing structure for the high-voltage winding of the large-capacity high-voltage transformer can be effectively solved.
Description
Technical field
The utility model relates to a kind of thread guide devices of winding overhang outlet of the single-phase twin columns parallel-connection structure that is used for the high-voltage large-capacity transformer.
Background technology
High-voltage connection is one of parts of most critical in the transformer, and the one end links to each other with the head end of high pressure winding, and the other end is connected with sleeve pipe.Since transportation boundary and transport heavy quantitative limitation, the high-voltage large-capacity transformer two post parallel-connection structures that adopt more, and 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.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of make lead-in wire around electric field even, increase the transformer two posts end in parallel 500kV outgoing line device of coefficient of safety.
The utility model adopts following technical scheme: the utility model comprises two balance pipes that penetrate the winding outlet, is arranged on two voltage equalizing balls between balance pipe, the two ends of two balance pipes are set in respectively in the voltage equalizing ball, and two balance pipes are connected by the securing member that is provided with in connector and the voltage equalizing ball.
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.
The utility model balance pipe end is provided with shading ring, and balance pipe is sleeved in the insulating paper cylinder.
The extremely long-pending effect of the utility model is as follows:
The utility model adopts split-type structural, and mainly be divided into three parts: two ends are balance pipe, and the centre is a voltage equalizing ball.The utility model be convenient to go between installation of connection and balance pipe, voltage equalizing ball.In order to improve the lead-in wire electrode shape, reduce electric field and concentrate, the utility model has installed balance pipe additional outside high-voltage connection, and its effect is that electric field becomes comparatively even around making lead-in wire, increase coefficient of safety, effectively solved the two posts outlet structure problem in parallel of high-voltage large-capacity transformer high-voltage winding.
