the shaft voltage monitoring unit 301 is connected with the large-shaft grounding carbon brush switching device 302 through a wire, when the shaft voltage is measured, the shaft voltage monitoring unit 301 sends a signal to the large-shaft grounding carbon brush switching device 302, and the large-shaft grounding carbon brush switching device 302 is disconnected by using a large-shaft grounding carbon brush grounding loop; when the shaft voltage is not measured, the shaft voltage monitoring unit 301 signals the large shaft grounding carbon brush switching device 302, and the large shaft grounding carbon brush switching device 302 is connected by using a large shaft grounding carbon brush grounding loop.
The generator bushing 400 is in contact with a generator journal 300a through an oil film, the carbon brush 300c is in frictional contact with a generator rotating shaft 300, the shaft voltage monitoring unit 300b-1 and the carbon brush 300c connected with the shaft insulation monitoring unit 401 are mutually independent, the current transformer 300b is sleeved on the generator rotating shaft 300 and keeps a certain distance with the generator rotating shaft, and the current transformer 300b is connected with the shaft current monitoring unit 300b-1 through a lead and used for collecting shaft current of the generator rotating shaft 300.
In summary, if the shaft voltage and the shaft current are not changed, and the insulation resistance between the insulating layer copper foil 400b and the bearing bush 400 or the generator rotating shaft 300 tends to decrease, it indicates that the insulation of the bearing bush insulation base 400a is not qualified; if the shaft current is unchanged and the shaft voltage tends to increase, it indicates that the large-shaft grounding carbon brush switching device 302 has a fault; if the shaft current is increased and the shaft insulation tends to be reduced, the damage to the surface of the engine journal 300a or the engine bearing bush 400 can be judged in advance;
the maintainers preliminarily judge the fault points of the equipment according to the diagnosis condition of the data curve diagram of the monitoring software in the monitoring computer 300b-3, and timely carry out state maintenance work, thereby avoiding the faults of the shaft neck surface and the bearing bush of the hydraulic generator and further improving the operational reliability of the hydraulic generator.
