DC AFCI 성능평가를 위한 UL1699B 표준에 따른 시험설비 구축

초록

This paper deals with the implementation of test facility for DC AFCI(Arc fault circuit interrupter) series arc detection performance evaluation based on UL1699B standard. The implemented test facility consists of DC source, decoupling network, line impedance, inverter and arc generator. The developed electric arc generator enables precise control for spacing between the arc electrodes. Implemented test facility complies with a single full string model presented on UL1699B. Mode 1 to Mode 4 are presented as test modes. The test conditions of inverter voltage, current, minimum arc current conditions, electrode separation speed and distance are satisfied by implemented test facility when arcing occurred in all test modes. Also the series arc detection performance evaluation result of DC AFCI under the mode 1 condition is presented. The implemented test facility is expected to be applied to the series arc detection performance evaluation of DC AFCI under all test mode conditions.
