Abstract: In order to monitor the vacuum degree of vacuum interrupter on line, an acquisition system to collect electric field signal surrounding the vacuum interrupter was designed. The design ideas of capacitive coupling sensor and signal conditioning circuit were illustrated in detail. The data processing program for STM32F103C8T6 MCU and LabVIEW interactive interface was made. Experiments suggested that the acquisition system is able to effectively collect electric field signal surrounding the vacuum interrupter in different working conditions and can be used to monitor vacuum degree on line.

Keywords: vacuum interrupter; capacitive coupling sensor; electric filed signal; STM32F103C8T6 MCU; LabVIEW interactive interface
