Flexible connecting device for generator rotor conducting rod

Abstract

The invention discloses a flexible connecting device for generator rotor conducting rods. The flexible connecting device comprises connecting copper bars. The connecting copper bars are V-shaped flexible connecting copper bars. The number of the V-shaped flexible connecting copper bars is two. The two V-shaped flexible connecting copper bars are symmetrically arranged in an exciter shaft or a collector ring shaft. One ends of the connecting copper bars are fit with the conducting rods in the exciter shaft or the collector ring shaft, and the other ends of the connecting copper bars are fit with the conducting rods in a generator shaft. Operating holes and ventilating holes at different radial positions are arranged on the exciter shaft or the collector ring shaft. The flexible connecting device for generator rotor conducting rods has the advantages that the assembling process is simple and the assembling accuracy and the operating difficulty are reduced; the flexible structures of the connecting copper bars can absorb deformation caused by the heating of the conducting rods at the two ends and harmful thermal stress is eliminated; the air friction loss and the noise are reduced, the device is not apt to be polluted by foreign matters and the operation reliability is improved; and the ventilating holes and the operating holes can jointly form a cooling air duct to ventilate and cool the V-shaped connecting copper bars and the conducting rods and take the effects of reducing temperature and improving current conducting performance.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to a flexible connection device for a generator rotor conductive rod. Background technique [0002] The generator rotor conductive rod flexible connection device is a current connection device that leads the excitation current from the collector ring shaft or the exciter shaft to the generator rotor. There are two technical solutions for the existing generator rotor conductive rod connection device: [0003] 1. The contact copper bar is set on the end face of the collector ring shaft or the exciter shaft, and the contact copper bar is also set on the end face of the generator rotor. When assembling, use bolts to connect the collector ring shaft or the exciter shaft and the generator rotor together. The contact copper bars at the ends are then close together to conduct the excitation current from the shaft of the collector ring or the shaft of the exciter to the rotor of the gener...
