Example Embodiment
The in-situ digitization device of the analog transformer provided by the present invention is described in detail as follows in conjunction with the drawings and embodiments:
The in-situ digitization device for analog transformers proposed by the present invention is characterized in that it includes three parts: N small-scale transformers, N signal acquisition boards, and a power supply. The output signal of the converter is converted into a voltage signal that can be sampled by a signal acquisition board. The signal acquisition board is used for analog-to-digital conversion, error correction and photoelectric conversion of the sampling signal, and receives sampling commands and sends sampling data through optical fibers; The power supply is used to supply the DC power supply for each acquisition board; the value range of N is a positive integer from 1 to 6; the connection relationship of each part is: the input terminal of each small transducer and the traditional electromagnet...
