Device and method for inspecting a condition of rotor windings of a generator
A device for inspecting the rotor windings of a generator includes a sequential logic circuit that generates a full-cycle pulse. A high-voltage full-cycle pulse matching generator couples the full-cycle pulse generated by the sequential logic circuit to form a corresponding transient bidirectional rotating magnetic field pulse. The transient bidirectional rotating magnetic field pulse is transmitted to two ends and a large shaft of the generator rotor winding through an impedance-matched connecting line. The transient bidirectional rotating magnetic field pulse generates a resonance effect with each large coil in the rotor. The pulse signal coupling feedback acquisition circuit couples all waveforms reflected by the generator rotor to form a magnetic field waveform, and the magnetic field waveform is transmitted to a data acquisition system by an operational amplifier. A central processing unit transmits a digital information stream to an upper computer.
