通过FDS软件建立了一个核电站继电器间火灾场景的模型,并通过模拟得到了继电器间电气柜内设定的两个测量点的温度、CO2及O2浓度。分析结果表明,若不设置自动喷水灭火系统(简称喷淋系统),继电器表面温度将超过失效温度;喷淋系统对降低温度,控制CO2及O2浓度均有一定的作用。
A model of fire scene between nuclear power station relays was set up by FDS software and the temperature, CO2 and O2 concentrations of two measuring points set in the electrical cabinet between relays were simulated. The analysis results show that if the sprinkler system is not set, the surface temperature of the relay will exceed the failure temperature; the sprinkler system has a certain effect on reducing the temperature, controlling the concentration of CO2 and O2.
