The novel slip ring device comprises a slip ring sleeve provided with an insulating layer, and an interior slip ring and an exterior slip ring which are sleeved and fixed on the slip ring sleeve. An inner insulating ring, a middle insulating ring and an outer insulating ring are sleeved on the slip ring sleeve. The inner insulating ring, the interior slip ring, a middle insulating ring, the exterior slip ring and the outer insulating ring are axially fixed on the slip ring sleeve in sequence through fixing bolts on which insulating bushings are sleeved. The novel slip ring device is further provided with a first conducting stud which axially threads through the outer insulating ring to be connected with the exterior slip ring and a second conducting stud which axially threads through the outer insulating ring, the exterior slip ring and the middle insulating ring sequentially to be connected with the interior slip ring; an insulating bushing is sleeved on the second conducting stub; and excitation leads are respectively led out from the first conducting stub and the second conducting stub.
Description
Technical field
The utility model relates to exchanging the brush synchronous generator, and the slip-ring device of brush synchronous generator is particularly arranged, and is specially a kind of novel generator slip ring device.
Background technology
At present, big-and-middle-sized interchange has brush synchronous generator slip-ring device generally to adopt the slip ring holder structure, and slip ring seat hot jacket is on axle, slip ring axially fastens on the slip ring seat, this structure, axially and radial dimension relatively large, if be used for size relatively the motor of anxiety just be difficult to be suitable for; The micro-machine slip-ring device generally adopts tube-in-tube structure, and excitation lead is drawn after being welded on the slip ring respectively, and this structure radial dimension is less but axial dimension is still bigger, is widely used in micro-machine, and has the hidden danger that earth fault takes place.
Summary of the invention
The utility model for the slip ring holder structure that solves existing generator slip ring device big-and-middle-sized interchange have exist axially in the brush synchronous generator and radial dimension bigger, be difficult to be applicable to the size problem of the generator of anxiety relatively; And the tube-in-tube structure axial dimension of slip-ring device is still big and have the problem of earth fault hidden danger in small generator.Provide a kind of novel generator slip ring device in order to address the above problem the utility model.
The utility model adopts following technical scheme to realize: comprise the slip ring sleeve which is provided with insulating barrier and overlap the inboard slip ring that is fixed on the slip ring sleeve, outside slip ring, also be with interior dead ring on the slip ring sleeve, middle dead ring, the external insulation ring, with the set bolt that is with insulating sleeve successively with interior dead ring, inboard slip ring, middle dead ring, outside slip ring and external insulation annulate shaft are to being fixed on the slip ring sleeve, simultaneously, also be provided with axially to pass on first conductive stud that the external insulation ring is connected with outside slip ring and its and be with insulating sleeve and axially pass the external insulation ring successively, outside slip ring, second conductive stud that middle dead ring is connected with inboard slip ring, excitation lead is respectively from first conductive stud, draw on second conductive stud.
Dead ring, inboard slip ring, middle dead ring, outside slip ring and the soaking of external insulation ring are placed on the insulating sleeve in described, have reduced the axial and radial dimension of slip-ring device effectively, are convenient to installation and removal; The setting of dead ring simultaneously can make between the slip ring axially accurately location, and has increased creepage distance and increased reliability.
Compared with prior art, the novel generator slip ring device that provides of the utility model has the following advantages:
(1) compact conformation, integraty is good.
(2) easy installation and removal.
(3) effectively reduce slip-ring device axially and radial dimension, can be fit to more eurypalynous generator.
(4) improve the reliability of slip-ring device, prevented earth fault.
