Abstract
The invention provides a large-current collector ring device of a generator, which aims to solve the problems of the existing collector ring, such as less number of conductive screws, low current carrying capacity, long axial length, poor rotor operation stability, and large rotor blank dimension. The device comprises collector rings arranged on a rotor, a current sharing ring, and conductive screws for connecting the current sharing ring and a conductive rod in the rotor, wherein the collector rings are connected with the conductive screws through the current sharing ring; two conductive screws are arranged on each collector ring; and four conductive screws on two collector rings are arranged on the same axial section of the rotor in a central symmetric manner. The four conductive screws in central symmetric arrangement are completely symmetric in structure and weight so as to eliminate vibration due to asymmetric weight while rotating, the collector ring has large outer diameter and short length, and the collector ring device has short axial length, thereby shortening the rotor length, improving rotor operation stability, reducing rotor blank dimension, and lowering the manufacture difficulty and material cost.
Description
Technical field
The present invention relates to technical field of generators, a kind of generator collector ring with high current device is provided.
Background technology
The collector ring of generator device is exciting current to be caused to the current conducting device of generator amature (rotating parts) by carbon brush holder (stationary parts), and existing collector ring of generator device has two kinds of technical schemes:
One, device is comprised of 2 collector rings, 4 contact screws.Each collector ring is connected with 2 contact screws, and 2 groups of contact screws lay respectively on 2 axial cross sections of generator amature, and structure and weight are asymmetric, have intrinsic imbalance, and whole collector machine axial length is large, and rotating stability is low; The rotor blank size is long, and manufacture difficulty and material cost are high; Contact screw and collector ring rigidity are closing, and installation accuracy requirement and operation easier are high.Its structure as shown in Figure 3 and Figure 4.
Two, device is comprised of 2 collector rings and flow equalizing ring thereof, 2 contact screws.Each collector ring is connected with 1 contact screw by flow equalizing ring, and contact screw quantity is few, flow equalizing ring covers 180 ° of angles of collector ring circumference, the CURRENT DISTRIBUTION lack of homogeneity, and current carrying capacity is little.Its structure as shown in Figure 5 and Figure 6.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of generator collector ring with high current device is provided.
The present invention for achieving the above object, by the following technical solutions:
A kind of generator collector ring with high current device, comprise the flow equalizing ring that is arranged on epitrochanterian collector ring, is arranged on the collector ring side, for connecting the contact screw of conducting rod in flow equalizing ring and rotor, it is characterized in that: 2 contact screws of described each collector ring configuration, collector ring is connected with 2 contact screws by flow equalizing ring, 2 contact screws are connected with the same electrode of conducting rod in rotor again, are arranged on the same axial cross section of rotor 4 contact screw Central Symmetries of 2 collector rings.
Described each collector ring is provided with 1 flow equalizing ring, and each flow equalizing ring forms a domain by 2 semi-rings, puts together on the collector ring side, covers 360 ° of collector ring sides angle, and each semi-ring is connected with the same electrode of conducting rod by 1 contact screw.
The present invention has following beneficial effect:
One, 4 contact screws of the present invention are arranged on same cross section, and whole collector machine axial length reduces, and has shortened generator amature length, and rotating stability improves, the rotor blank size reduction, and manufacture difficulty and material cost reduce.
Two, 4 contact screws of the present invention are arranged on same cross section, structure and weight full symmetric, the vibration caused due to the weight imbalance in the time of can eliminating rotation.
Three, each collector ring of the present invention is connected with 2 contact screws by the flow equalizing ring of side, and flow equalizing ring has been realized the all-round shunting of collector ring 360o, makes CURRENT DISTRIBUTION more even, has increased the current carrying capacity of device.
Four, flow equalizing ring of the present invention and contact screw are flexible has reduced the rigging position required precision closing, and operation easier reduces.
