초록

본 연구에서는 태양광 발전설비가 설치되어 있는 건물에서 화재가 발생할 경우 분사되는 물을 통해 전류가 흐를 가능성 및 감전의 위험성에 대해 고찰하였다. 분사되는 물을 수학적 모델을 통하여 해석 하였고, 물 전도도 측정을 위한 물분사 시스템을 제작하여 유속에 따른 물 저항값을 측정하여 수치적으로 예상한 값과 비교하였다. 실험과 수치계산의 결과로 태양광 발전설비 화재 시 고려되어야 할 사항들을 정의할 수 있게 되었다.

In this study we investigated the risk of electric shock and the possibility of current flow from the sprayed water when fire took place in a photovoltaic (PV) installed building. The sprayed water was analysed by using a mathematical model, a water spray system for water conductivity was made. With changing the initial water flow rate the water resistance was measured, and compared with the numerically expected value. As the experimental and numerical computing result, we were able to define the requirements that must be considered in the fire of PV systems.
