  • Central point positioning determination device and central point positioning method thereof for rotor coil of large-scale steam turbine generator
    Patent number: 10634480
    Abstract: A central point positioning determination device and a central point positioning method thereof for a rotor coil of a large-scale steam turbine generator includes a control device, a pulse acquisition device, and a pulse generation device. The pulse generation device is connected to connection ends of a positive terminal and a negative terminal of the rotor of the generator, and a rotor body of the rotor. The control device controls the pulse generation device to send pulses to the positive terminal, the negative terminal, and the rotor body of the rotor of the generator. By doing so, the central point of the rotor coil can be found conveniently and quickly.
