But these two methods have certain disadvantages. The data obtained by the recorder cannot be directly transmitted in real time, and can only be temporarily stored in the recorder, and can only be taken out when the unit is shut down; the other is transmitted by wireless communication. Although the data can be sent and received in real time, due to the complex electromagnetic environment inside the hydro-generator, the wireless data transmission is easily disturbed, and due to the power supply problem, the wireless transceiver equipment cannot work for a long time, so the rotor of the hydro-generator has not yet been realized. Online real-time monitoring of data

Embodiment Construction
[0012] Such as figure 1 As shown in the figure, a data communication collector ring for the rotor of a hydro-generator, the eight holes on the upper surface of the collector ring bracket 1 penetrate the tightening screw 2, and then penetrate the insulating spacer 5 on each tightening screw 2 , and then penetrate a communication slip ring 6, a total of four communication slip rings 6 are used, and an insulating spacer 5 is placed between every two communication slip rings 6 for insulation. The communication slip ring 6 and the slip ring Install insulating pads 5 between the brackets 1 for insulation, install insulating pads 5 between the communication collector ring 6 and the washer 4 for insulation, and finally install insulating pads 5 and washers 4 at both ends of the tensioning screw 2 And lock nut 3 and tighten the communication collector ring 6 by thread.
[0013] Such as figure 2 As shown, each communication collector ring 6 is in contact with eight carbon brushes 7 o...

A hydro generator rotor data communication collecting ring disclosed by the present invention comprises a collecting ring support, a tensioning screw, a washer, a locking nut, insulating cushion blocks, communication collecting rings and a carbon brush. The insulating cushion blocks are arranged between the communication collecting rings and among the communication collecting rings, the collecting ring support and the locking nut for insulation, thereby preventing the short circuit. The carbon brush and the communication collecting rings form an electric power channel and a communication channel from a central control system to a rotor to provide the electric power and communication support for a data acquisition device on the rotor, so that the data acquired by the data acquisition device on the rotor can be transmitted to the central control system real-timely, and accordingly, the real-time and online monitoring of the hydro generator rotor data is realized.
Description
technical field [0001] The invention relates to a water turbine generator rotor data communication collector ring. Background technique [0002] In hydroelectric generator sets, the parameters on the rotor, such as magnetic pole temperature, cooling air volume and other data, are important data to characterize the operating status of the unit. These data have a greater impact on the health of the unit. However, since the rotor keeps rotating, how to transmit the collected data to the central control system becomes a key issue. [0003] At present, there are two main methods for monitoring rotor parameter data, one is to install a data recorder on the rotor, which rotates with the rotor, and records the rotor parameters in real time when the unit is running; the other is to install a wireless data recorder on the rotor The transceiver device uploads the data wirelessly. But these two methods have certain disadvantages. The data obtained by the recorder cannot be directly tr...
