Abstract

More than 70% of the electric fire cases happen in this country are caused by arc. This paper aims to prepare measures of preventing electric fires resulted from arc by analyzing the technical standards and related regulations on the existing circuit breaker. Based on the study, we concluded that the technical and legal standards of the arc detector should be separately regulated from those of existing circuit breaker, considering the characteristics of arc detectors. Accordingly, we suggested in this paper that the arc detector related regulations should either be added to the existing circuit breaker related regulations, or to be handled separately. For effective prevention of electric fires caused by arc, it is urgently required to install arc detector and it is, therefore, appropriate to make it mandatory to install an arc detector. Under the given circumstance, it is suggested that the arc detector related regulations should be added to the existing regulations for the circuit breaker. The technical standards of arc detectors should reflect the arc judgement specification, breaking threshold of arc and the range of unnecessary signal that breaker should not react to respond.

국내에서 전기 화재의 70% 이상이 아크로 인하여 발생하고 있다. 본 논문에서는 이를 예방하기 위한 방안을 마련하기 위하여 기존의 누전 차단기에 관한 기술기준 및 규정을 분석하였으며, 아크 검출기에 관한 기술기준 및 규정은 아크의 특성을 고려하여 기존의 누전 차단기에 관한 기술기준 및 규정과는 별도로 제정되어야 한다는 결론을 얻었다. 따라서 본 논문에서는 아크 검출기 관련 규정은 기존 누전 차단기의 관련 규정에 추가 되거나 이것과 별개인 규정으로 제정되어야 한다고 제안하였다. 특히 아크로 인한 화재를 예방하기 위해서는 아크 검출기의 신속한 보급이 필요하고 그 설치를 의무화하는 것이 바람직하다. 따라서 이 같은 여건을 고려했을 때 기존 누전차단기 규정에 아크 검출기 관련 사항들을 추가할 것을 제안하였다. 아크 검출기의 기술 기준에는 아크의 판단 규격과 차단 임계치, 그리고 차단기가 반응하지 말아야 할 불요신호의 범위 등이 반드시 반영되어야 한다.
