Multi-voltage output device of twelve-phase rectification generator

Abstract

The invention discloses a multi-voltage output device of a twelve-phase rectification generator, which comprises an insulating plate, 12 columns of outgoing lines X1, U1, Y1, V1, Z1, W1, X2, U2, Y2, V2, Z2 and W2 are sequentially arranged on the insulating plate from left to right, each column of outgoing lines is provided with four wiring studs, the wiring studs are connected through a short-circuit copper bar, and the connection modes of the wiring studs and the short-circuit copper bar comprise a wiring mode I and a wiring mode II; the wiring mode I is that four wiring studs in each column of outgoing lines are in short-circuit connection through a short-circuit copper bar, the upper wiring stud and the lower wiring stud are in short-circuit connection through a short-circuit copper bar, and four paths of stator windings in the wiring mode I are connected in parallel; according to the wiring mode II, 12 columns of outgoing lines are divided into six groups including X1 and U1, Y1 and V1, Z1 and W1, X2 and U2, Y2 and V2, Z2 and W2, two wiring studs in the same row in the two columns of outgoing lines of each group are connected in a short-circuit mode through a short-circuit copper bar, and stator windings are connected in parallel in one circuit in the wiring mode II.

Description

technical field [0001] The invention relates to a multi-voltage output device of a twelve-phase rectifier generator. Background technique [0002] At present, before the existing generator leaves the factory, the connection method of the stator winding has been impregnated with heat and cured, and it is impossible to switch between multiple voltage outputs. In other words, the generator output has only one voltage form (limited fluctuation range), Moreover, the switch between different voltages needs to be realized through a transformer, which is not only large in size and high in cost, but also needs 8 transformers to complete the three voltage levels of a 12-phase generator. Contents of the invention [0003] The object of the present invention is to provide a multi-voltage output device for a twelve-phase rectifier generator in order to solve the above deficiencies in the prior art. [0004] A multi-voltage output device for a 12-phase rectifier generator, comprising a...
