Device and method for detecting inter-turn electromagnetic pulse vibration wave characteristic of turbogenerator rotor winding

A device for detecting an inter-turn electromagnetic pulse vibration wave characteristic of a turbogenerator rotor winding, comprising an ultra-large-capacity internal resistance signal source, wherein the ultra-large-capacity internal resistance signal source is connected to an ultra-high-speed time sequence control circuit, the ultra-high-speed time sequence control circuit is connected to a positive electrode and a negative electrode of a rotor winding through a parasitic inductive power supply via a positive electrode load wave guiding line and negative electrode load wave guiding line, and the positive electrode and the negative electrode of the rotor winding are connected to an ultra-high-speed acquisition circuit through an operational amplifier circuit;

• the ultra-large-capacity internal resistance signal source matches with an average time constant of a circular polarization characteristic for each turn of the winding, and generates an energy width of a power circular polarization characteristic wave matching with a full response time constant of the rotor winding;
• the parasitic inductive power supply performs circular waveguide coupling exchange on input and output coupling circularly polarized waves (CPWs) of the positive electrode and the negative electrode;
• the positive electrode load wave guiding line and the negative electrode load wave guiding line couple CPWs concurrently to a positive electrode and a negative electrode of a rotor;
• the operational amplifier circuit combines, couples and amplifies signals for concurrent circularly polarized transmission and reception;
• and
• the ultra-high-speed acquisition circuit acquires a waveform depending on a circularly polarized dual-signal emission source, an induced polarization source at each turn, a disymmetric circularly polarized waveguide load, and a time constant for maintaining energy of the signal source.
