Aiming at the cumbersome problem of arc signal acquisition in the study of aviation fault arc, this paper designs an aviation arc fault generator which based on LabVIEW. The system consists of three parts: LabVIEW upper computer, DSP control system and arc generator device. First of all, the arc generator is controlled by the LabVIEW virtual key to trigger the fault arc. Secondly, the data is transferred to LabVIEW for real-time display and storage by serial communication. A large number of experimental tests show that the newly designed experimental platform can realize the automatic control of arc fault trigger and the accurate collection of arc characteristics, and simplify the data acquisition process with good practicability and user-friendly design.
