Description
Technical field
The utility model relates to hydraulic generator field, particularly a kind of seal of hydraulic generator rotor.
Background technology
A hydraulic generator occurs that in running rotor insulation reduces, and adopts segmented research technique and comprehensive analysis, accurately finds out rotor insulation and reduce position.By analyze rotor insulation reduce be due to rotor-exciting red copper row enter the insulating sleeve of core through screw rod in upper shaft, cushion block in design Shortcomings part cause, in order to thoroughly remove a hidden danger, insulating sleeve, cushion block are transformed, through operation test in a few years after process, there is not the situation that rotor insulation reduces again, for the insulation of process similar structures hydraulic generator rotor reduces supplying method.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of seal of hydraulic generator rotor, can effectively prevent rotor insulation from reducing, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of seal of hydraulic generator rotor, comprise insulating sleeve and cushion block, described insulating sleeve and cushion block removably connect, cushion block and insulating sleeve are socketed on rotor, cushion block is provided with screwed hole, cushion block is connected with generator bolt, the madial wall of described insulating sleeve is provided with hairbrush, the end of insulating sleeve is pyramidal structure, the sidewall of insulating sleeve is uniformly distributed multiple small opening, is provided with bearing between the end of pyramidal structure and rotor.
Preferably, described small opening is bellmouth.
Preferably, the joint face of described cushion block and insulating sleeve is provided with multiple rectangular recess, and described insulating sleeve is provided with multiple rectangular cam with on the joint face of cushion block in corresponding position.
Preferably, fixed between described insulating sleeve and cushion block by right angle splint, right angle splint is connected with insulating sleeve and cushion block bolt respectively.
Preferably, the sidewall of described insulating sleeve is provided with air inlet.
Preferably, the end of described pyramidal structure is provided with notch, and bearing is arranged in notch.
The beneficial effect of above technical scheme is adopted to be: in the seal of the hydraulic generator rotor of the utility model structure, cushion block is fixed on generator, insulating sleeve is relative fixing by right angle splint with cushion block, insulating sleeve has bearing, prevent carbon dust from entering insulating sleeve inside, generator is in the process of rotating, insulating sleeve is driven to rotate together, the hairbrush of insulating sleeve inwall contacts with rotor, carbon dust is prevented to be attached on rotor surface, ensure the insulation resistance of rotor, carbon dust can by small opening under gravity, leave insulating sleeve inside, cushion block and insulating sleeve are linked together by rectangular recess and rectangular cam, what ensure that between cushion block with insulating sleeve is relative fixing, the sidewall of insulating sleeve is provided with air inlet, conveniently clear up by the carbon dust of wind-force to insulating sleeve inside.
