Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0030]The invention provides a high-potential current acquisition system that can be used under raining conditions. The system can be used under high voltage, electromagnetic conditions of strong interference and raining experimental conditions. In the present invention, the sampling resistor converts the current signal of the discharge channel into a voltage signal, and the voltage data collected by the data acquisition card in the data acquisition box is converted into an optical signal and then output through the optical fiber. On the low-voltage side, the receiving end of the photoelectric conversion module in the data receiving device receives the optical signal, converts it into an electrical signal, and transmits it to the computer. Use the trigger signal generated by the trigger circuit to trigger the data acquisition card to work. Different trigger ...
