Description
Technical field
The invention belongs to machinery check and repair ancillary technique fields, are to be related to a kind of carbon brush for electric machine milling tools more specifically.
Background technique
The RAM generator system (namely control rod drive mechanism power-supply system) of nuclear power station is the control of reactor control rod
Power-supply system provides power supply to reactor control rod by two generators, and two-way mutual backup redundancy generates electricity at this two
In the excitation system of machine, exciting current is contacted by four carbon brush with the slip ring being fixed on generator amature, to rotor windings
Exciting current is provided, under normal reactor operation operating condition, generator need to be maintained at operating status, Generator Slip Ring and carbon brush it
Between always exist friction, so carbon brush is continuously in state of wear under accidental conditions, cause per after a period of time, when
After carbon brush abrasion to certain limiting value, need to stop transport corresponding generator the carbon brush more renewed, and unit remembers I/O state, at this time
If an other RAM alternator failure, it will result directly in reactor chaser and jump heap, in view of the importance of ram system, energy
It is no to safely and steadily run, it is directly related to the safe and stable operation of reactor.
It is to remove old carbon brush after generator is stopped transport, installation is new at present for the replacement of RAM generator carbon brush
Carbon brush, need to be by spare part carbon brush to guarantee contact between carbon brush and slip ring well but because new spare part carbon brush is rectangular shape
Bottom is polished into after certain radian, is allowed to fit with slip ring surface radian, guarantees well connecing for carbon brush and slip ring with this
Touching.Currently, the operational method of use is generator at the scene to guarantee that the radian of carbon brush polishing can be preferably bonded with slip ring
Slip ring surface is inserted in one layer of sand paper, and spare part carbon brush is installed to certain spring pressure is imposed on brush carrier, is sent out by manual rotation
Come carbon brush of polishing, this method can make to polish the carbon brush radian come and live slip ring surface utmostly rotor mode
Fitting, but also therefore increase generator stoppage in transit time, make reactor control rod control power-supply system lose back-up circuit
Time lengthens, and is unfavorable for the safe and stable operation of reactor, and the method is more clumsy, manual rotation's rotor is laborious, right
Good teamwork degree between operation group member requires height, is in addition easy to leave the adhesive plaster of adhesion sand paper on Generator Slip Ring
Colloid is remained, does not clean out such as, can lead to generator under normal operating conditions, spark phenomenon occurs in carbon brush, occurs serious
Event.
In conclusion polishing currently without a preferable method or tool carbon brush, so as to can to polish
Carbon brush out fits with live slip ring to the greatest extent, but can be reduced generator carbon brush because be artificially introduced factor generation as
The risks such as sparking, while can be shortened generator idle time again, improve the security and stability of reactor.
