Technical field
The present invention relates to technical field of generators, be specifically related to a kind of flexible connecting device of generator amature conducting rod.
Background technology
Generator amature conducting rod flexible connecting device is that exciting current is caused the current connection apparatus of generator amature by current collection annulate shaft or exciter shaft, and existing generator amature conducting rod jockey has two kinds of technical schemes:
One, on current collection annulate shaft or the exciter shaft end face contact copper bar is set; The generator amature end face is provided with the contact copper bar equally; With bolt current collection annulate shaft or exciter shaft are put together on generator amature during assembling; The contact copper bar at two ends abuts against together thereupon, and exciting current is conducted to generator amature by current collection annulate shaft or exciter shaft.Device mainly is made up of the contact copper bar at two ends.Because the contact copper bar at two ends is the rigidity contact, the position of related features of contact copper bar and axial end requires very strict, assembly technology difficulty, the corresponding raising of technology cost.If the overproof meeting of fitted position causes the copper bar loose contact, electrical loss increases, and the contact copper bar is to be completely enclosed within rotating shaft inside, the heat radiation difficulty.
Two, an end of current collection annulate shaft or exciter shaft is provided with radially contact screw; Generator amature one end is provided with radially contact screw equally; At current collection annulate shaft or exciter shaft after generator amature puts together on; Link together with connecting the radially contact screw of copper bar, electric current is conducted to generator amature by current collection annulate shaft or exciter shaft two ends.Since the radially contact screw at two ends with is connected copper bar and all gives prominence to the surface of rotating shaft, will produce the windage loss during operation, the reduction generator efficiency; Also can increase noise simultaneously, become an important noise source of generator; Radially contact screw be connected copper bar and also receive outside contamination easily, cause the rotor ground fault fault, influence the safe operation of generator.
Summary of the invention
To above-mentioned prior art, the technical problem that the present invention will solve is: generator amature conducting rod jockey assembly technology requires high, heat radiation difficulty, influence generator efficiency, noise greatly, have a problem such as potential safety hazard.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of flexible connecting device of generator amature conducting rod comprises the connection copper bar, it is characterized in that; Said connection copper bar is V-shaped connection copper bar; This flexibly connects copper bar has two, is arranged symmetrically in the inside of exciter shaft or current collection annulate shaft, and the conducting rod in an end and exciter shaft or the current collection annulate shaft is closing; Conducting rod in the other end and the generator shaft is closing, and two connect the positive and negative electrode that copper bar connects conducting rod respectively; Said exciter shaft or current collection annulate shaft are provided with handle hole and ventilation hole, and the perforate radial position of this handle hole and ventilation hole is different.
The distance in said handle hole and axle center is greater than the distance in said ventilation hole and axle center.
Said operation hole count is 2, and symmetric arrangement.
Said ventilation hole adds up to even number, and symmetric arrangement.
Compared with prior art, beneficial effect of the present invention shows:
One, V-type flexibly connects copper bar and greatly reduces the rigging position required precision that connects copper bar two ends conducting rod, has simplified assembly technology, has reduced operation easier; Flexible structure can absorb the distortion that two ends conducting rod heating causes, and eliminates harmful thermal stress;
Two, connect the inside that copper bar is installed in exciter shaft or current collection annulate shaft; The outer surface of axle is a smooth surface; Eliminate contact screw during operation and be connected windage loss and the noise that the outstanding axle of copper bar surface type becomes, improved generator efficiency, reduced the noise of generator; Avoided connecting the rotor ground fault fault that the copper bar pollution causes, improved operational reliability;
Three, ventilation hole forms the turnover air channel with handle hole, utilizes the centrifugal pressure reduction between two holes that the axle rotation forms to produce natural draft during operation, and V-type is connected the cooling of ventilating of copper bar and conducting rod, plays the effect that reduces temperature and raising conduction of current ability.
