Abstract

The embodiment of the invention provides an electric arc current waveform signal reduction method and system. The method comprises the following steps: processing electric arc waveform data to obtain an initial electric arc waveform signal; and processing the initial electric arc waveform signal by using a power amplifier to obtain a target electric arc current waveform signal.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, and more specifically, to a method for restoring an arc current waveform signal and a system for restoring the arc current waveform signal. Background technique [0002] With the continuous development of electrical technology, various types of electrical equipment also appear and play an indispensable role in people's production and life. If electrical equipment fails, it may cause an electrical fire, which will adversely affect people's lives and property safety. Wherein, electrical equipment faults may include short circuit faults, overload faults, leakage faults and arc faults. [0003] For short-circuit faults, overload faults and leakage faults, they can be detected by circuit breakers, fuses and leakage protectors. Since the above-mentioned equipment is difficult to detect arc faults, the research on the detection technology of arc faults is the key to the prevention and con...
