Abstract: The provided is a method for detecting AC and DC arc faults based on Rogowski coil magnetic coupling resonance, where a line to be detected passes through a uniformly wound Rogowski coil, and by adjusting the dimensions of the framework structure, the number of winding turns, and the values of a parallel-connected inductor and capacitor, a specified resonant frequency is obtained; when an arc fault occurs in the line to be detected, the Rogowski coil amplifies the characteristic frequency band signal corresponding to the resonant frequency by means of magnetic coupling resonance, so as to detect an arc fault state.

Abstract: This application provides an interrupt processing method, apparatus, and device. The method includes: Firmware receives a plurality of interrupts in a first duration, where the plurality of interrupts are triggered when non-fatal errors occur in a hardware layer. The firmware masks, based on interrupt information and layered masking information of the plurality of interrupts, an interrupt that is of a target to-be-masked object corresponding to the plurality of interrupts and that is after the first duration, where the layered masking information indicates a plurality of to-be-masked objects, a plurality of to-be-masked objects are obtained by layering transmission of the interrupts, and the plurality of to-be-masked objects include the target to-be-masked object. The firmware sends the interrupt information of the plurality of interrupts to a kernel driver.
