요약

본 연구에서는 가스계 소화설비시스템이 설치된 방호구역에 소화농도유지시간 성능실험인 밀폐도 시험(Enclosure Integrity Test)를 진행하여, 성공에 미치는 사전조치요인에 대하여 실험하였다. 국내외에 발전소 방호구역에 사전 조치를 취한 방호구역과 사전 조치를 취하지 않은 방호구역으로 나누어 Enclosure Integrity Test를 진행하였다. 따라서, 사전조치 여부에 따라 시험의 성공률을 알아보고, 각각의 가스계 소화시스템 및 실의 종류에 따른 Enclosure Integrity Test의 실패 요인, 설계 농도 유지시간 및 체적대비 누설면적의 크기를 확인하였다. 그리고 사전조치를 수행하여 Enclosure Integrity Test의 성공률이 증가되는 것을 알 수 있으며, 실패에 의해 반복되는 실험의 수를 줄임으로 인하여 발생되는 비용을 절약할 수 있었다.

Abstract

The present study was aimed to analyze enclosure integrity test, which is the performance experiment of soaking time, in a fire zone equipped with gaseous extinguishing system in an effort to find understand the effect of precaution factors upon the success of fire extinguishment. To achieve the goal of this study, it divided the fire zones of internal and external power plants into ones taking precaution measures and not taking them and then enclosure integrity test was given respectively. Therefore, this study examined the success rate if the test according to the presence and absence of the precaution measure and confirmed the failure factors, designed concentration soaking time and proportion of leakage area to total volume area by type of gaseous extinguishing system and rooms. Precaution measures were applied to the fire zones without them to confirm the increase of the success rate of enclosure integrity test. By doing so, it was found that reduced number of experiments caused by failure led to cost saving.
