| description | The present invention relates to a distribution board, and more particularly to a distribution board having a self-testing function. The present invention is to provide a distribution board which can periodically test characteristics of zero-sequence harmonic filtering of a power distribution apparatus, a lifespan of a zero-sequence harmonic filter, and the like. For this purpose, the distribution board according to a preferable embodiment of the present invention comprises: an overload protection unit which measures the temperature of a zero-sequence harmonic filter via a temperature sensor installed in the zero-sequence harmonic filter, blocks the zero-sequence harmonic filter by turning off a switch when the temperature of the zero-sequence harmonic filter excesses a preset temperature upper limit, and operates the zero-sequence harmonic filter again by turning on the switch when the temperature of the zero-sequence harmonic filter is equal to or lower than a preset lower limit temperature while the zero-sequence harmonic filter has been blocked; and a performance evaluation unit which tests performance of the zero-sequence harmonic filter by using zero-sequence components introduced into a commercial power system during a period for which the zero-sequence harmonic filter has been blocked.
본 발명은 분전반에 관한 것으로 보다 상세하게는, 자가 진단 기능이 내장된 분전반에 관한 것이다. 본 발명은 전력분배장치의 영상고조파필터링 특성 및 영상고조파필터의 수명 등을 주기적으로 진단할 수 있는 전력분배장치를 제공하는 것을 목적으로 한다. 상기와 같은 목적을 달성하기 위한 본 발명의 바람직한 일 실시예에 따른 분전반은 영상고조파필터에 설치된 온도센서를 통해 영상고조파필터의 온도를 계측하고, 상기 영상고조파필터의 온도가 기 설정된 상한온도를 초과하면 스위치를 오프시키는 것에 의해 상기 영상고조파필터를 차단하고, 상기 영상고조파필터가 차단된 상태에서 상기 영상고조파필터의 온도가 기 설정된 하한온도 이하가 되면 상기 스위치를 온시키는 것에 의해 상기 영상고조파필터를 재투입하는 과부하보호부; 상기 영상고조파필터가 차단된 시간에 상용전력계통으로 유입되는 영상분을 사용해 상기 영상고조파필터의 성능을 진단하는 성능평가부를 포함한다. |
