<p>Disclosed are a distributing board (high-tension panel, low-tension panel, panel board, motor control board) having an arc monitoring function by detection of infrared ray of a multi-wave band and a monitoring method thereof, and a monitoring method thereof. The distributing board (high-tension panel, low-tension panel, panel board, motor control board) comprises: a first optical filter filtering and outputting light in a wavelength of 4.4-5.0μm; a second optical filter filtering and outputting light in a wavelength of 4.35μm; an infrared sensor detecting infrared rays among light in a wavelength of 4.4-5.0μm outputted from the first optical filter and light in a wavelength of 4.35μm outputted from the second optical filter; an amplifier outputting an amplified signal by amplifying the infrared rays detected from the infrared sensor; a band pass filter passing a frequency signal of 100-1,000 Hz of the amplified signal outputted from the amplifier; and an arc determining module determining whether arc is generated by analyzing the frequency signal of 100-1,000 Hz band-passing in the band-pass filter. According to the distributing board (high-tension panel, low-tension panel, panel board, motor control board) having an arc monitoring function by detection of infrared ray of a multi-wave band and the monitoring method thereof, the distributing board is configured to monitor whether arc is discharged due to contact inferiority, and short circuit through frequency analysis, thereby accurately detecting and quickly treating the dangerous arc generation resulting in fire.</p> |
