摘要
分析3种常见情况(燃具无熄火保护,无泄漏报警系统;燃具有熄火保护,无泄漏报警系统;燃具有熄火保护,有泄漏报警系统)的室内燃气系统组成及对应的可靠性故障树结构。对每种情况的顶事件(燃气泄漏无报警)概率及事故后果与损失进行计算,计算3种情况下室内燃气系统的风险。
The components of indoor gas system and the corresponding reliability fault tree structure in three common cases （gas appliances without flame failure device and leakage alarm system; gas appliances with flame failure device,without leakage alarm system; gas appliances with flame failure device and leakage alarm system） are analyzed. The probability of the top event （no alarm for gas leakage） and the consequences and losses of the accident in each case are calculated,and the risk of the indoor gas system in 3 cases is calculated.
