UHF ARC ANALYSIS PROCESSING SYSTEM OF SWITCHBOARD USING UHF ANTENNA AND PROCESSING METHOD THEREOF

摘要

The present invention can detect the occurrence of an arc by detecting an electromagnetic wave due to arc generation on a distribution line, analyzing the detected arc signal, and detecting a position of an arc using the detected arc signal analysis. And more particularly, to an arc signal analysis processing system and method for an arc panel.According to another aspect of the present invention, there is provided an arc detection method using an arc signal analysis process of an ASSEMBLY using an UHF antenna, the method including detecting an electromagnetic wave received by one or more UHF antennas disposed adjacent to a distribution line, Detecting step; A filtering step of removing impulse noise from the electromagnetic waves respectively detected in the electromagnetic wave detecting step; A statistical analysis step of calculating the electromagnetic wave as a property or parameter set face using statistical analysis for each of the electromagnetic waves whose impulse noise has been eliminated through the filtering step; A similarity point detecting step of detecting a similarity point; An arrival time difference detection step of detecting arrival time differences of electromagnetic waves received from the plurality of UHF antennas; And an arc generation position tracking step of tracking an arc generation position using the detected arrival time difference.;
