Abstract

The invention belongs to the technical field of transformer manufacture and particularly relates to a coil outlet end transition connecting device of a high-voltage current conversion transformer and a manufacture method of the coil outlet end transition connecting device. The coil outlet end transition connecting device of the high-voltage current conversion transformer comprises a coil, a lead wire and a coil outlet end conducting wire and is characterized in that the lead wire is welded with the hole opening end of a copper plate, the coil outlet end conducting wire is welded with the outlet end conducting wire end of the copper plate, insulation paper is respectively covered outside the lead wire, the coil outlet end conducting wire and the copper plate, and insulation paper boards are arranged between the copper plate and coil end part coil cake. The manufacture method comprises the following steps that: a, a transition connecting copper plate is manufactured; b, connection, treatment and bandage are carried out; and c, the placement and the fixation are carried out. The coil outlet end transition connecting device of the high-voltage current conversion transformer has the beneficial effects that the end part electric field distribution of the coil is improved, the insulation reliability is improved, and the safety and the reliability of the transformer are ensured.

Description

(1) Technical field [0001] The invention belongs to the technical field of transformer manufacturing, and particularly relates to a high-voltage converter transformer coil tap transition connecting device and a manufacturing method thereof. (2) Background technology [0002] At present, the existing transformer coil lead-out structure and its manufacturing method are defective, resulting in uneven distribution of electric field intensity at the coil end, low insulation reliability, and certain potential safety hazards. Therefore, a transition connection device for the coil outlet of a high-voltage converter transformer, which can move the coil outlet from the outside to the middle or inside, and a manufacturing method thereof are invented. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides a high-voltage converter transformer coil outlet transition connection device and a manufacturin...
