Description

technical field [0001] The invention relates to the field of high-voltage electrical technology, in particular to an expert system-based high-voltage discharge circuit impedance self-matching method and device. Background technique [0002] Safety accidents caused by lightning strikes during flight occur frequently. According to statistics, aircraft with fixed routes are struck by lightning once a year on average. Therefore, it has always been the goal that people strive to minimize the impact of atmospheric lightning environment on flight safety. [0003] Most of the aircraft's electronic and electrical equipment are installed inside the airframe, and are generally not subject to direct lightning strikes, but lightning may cause indirect interference effects on these equipment. The transient strong electromagnetic field and high-level structural voltage generated by lightning discharge will induce voltage and current surges in the aircraft's internal systems and circuits, ...
