The utility model solves the technical problems on additional loss existed in the background technology, or complex process, high cost, as well as small scope of application. Under the condition of retaining product impact properties, the utility model makes the same magnetic field position of each wire in wires connected in parallel, thereby reducing the eddy loss of the coil in the middle end part of leakage magnetic field with high reliability of product operation as well as wide scope of application.
Description
Technical field
The utility model relates to a kind of coil of oil immersed power transformer, relates in particular to a kind of compound wire axially arranged side by side that is applicable to EHV transformer, commutator transformer.
Background technology
According to the influence of magnetic field, show by analysis: because the existence of leakage flux has supplementary load loss in the lead of transformer coil coil.This supplementary load loss comprise the eddy current loss of lead and the incomplete transposition loss of lead.
According to the difference of transformer coil wire form, in order to reduce eddy current loss, be convenient to coil winding simultaneously, when sectional area one timing of the every circle lead of transformer coil, mainly take following manner:
Compound wire for strip conductor or two folded parallel connections or triple-lap parallel connection reduces supplementary load loss by the radical in parallel that increases lead.Because the residing magnetic field position difference of each root parallel conducting wire, the transposition of multiple conducting wires in unit length is incomplete, along the coil width of cloth to leakage flux density linearly successively decrease by interior radial outer diameter again, so still have bigger supplementary load loss.
Adopt transposed conductor,, during establishment, must adopt special equipment, technological equipment and detecting instrument though can reduce the supplementary load loss of coil, the processing technology complexity, cost is higher.Because the welding procedure complexity, its applicable scope is also less.
Summary of the invention
