Patent number: 11971452Abstract: A device and a method for nondestructively detecting a transient characteristic of a conductive screw of a turbo-generator rotor are provided. The device includes a personal computer (PC), an extremely-steep pulse generator, an ultra-high-frequency double-isolation transformer, and a pulse emitting and coupling module, which are connected in sequence. The pulse emitting and coupling module is connected to a load. A synchronous pulse receiving non-inductive divider circuit synchronously receives a characteristic waveform from the load, and the synchronous pulse receiving non-inductive divider circuit is connected to an ultra-high-speed analog/digital (A/D) module through a nonlinear saturation amplifying circuit that amplifies a signal. The PC receives a signal from the ultra-high-speed A/D module. The load includes a positive or negative excitation lead loop that is in a 180° symmetrical and instantaneous short-circuit state and a rotor shaft.Type: GrantFiled: April 25, 2021Date of Patent: April 30, 2024Assignee: HANGZHOU HENUOVA TECHNOLOGY CO., LTD.Inventors: Yuewu Zhang, Jianxi Liu, Yanxing Bao, Weihua Zha, Qianyi Zhang, Dongbing Liu, Weixing Yang, Xu Han, Miaoye Li, Zirui Wang, Junliang Liu, Jie Luo, Weitao Shen, Yu Fu, Han Gao
