Design of the Fault Arc Test System for the Aircraft Wire

To collect the various fault arc signals in the aircraft wire system, a fault arc test system is designed to simulate the series arc, the parallel arc and the wet short circuit arc. The series arc is generated by fault arc generator. The parallel arc is triggered by the dynamic wire cutting device. The wet short circuit arc is caused by water dripping device. The data acquisition module is used to upload the arc signal data to the upper computer for display and storage. The test results show that the fault arc test system designed in this paper can realize stable triggering of different fault arc and accurate acquisition of arc characteristic.
