摘要/Abstract

摘要： 为分析在运换流站阀厅防火封堵系统的耐火性能，选取两座换流站（模型1、2）封堵系统的关键区域，在碳氢（HC）升温曲线条件下，通过ANSYS软件模拟防火封堵系统的传热过程，分析了温度场、热通量和温度梯度等主要热力学参数，并通过耐火试验和一维热传导模型研究了封堵系统的升温特性。研究结果表明，由于方钢的高导热系数和传导效率，热流密度的最大值位于方钢（龙骨）位置；模型1背火面c1测温点温度超过180 ℃，不符合防火封堵系统的耐火极限要求；方钢（龙骨）位置测温点f1和f2的升温速率分别为0.047 1 ℃/s和0.015 9 ℃/s；基于一维热传导模型计算得到的温度值低于耐火试验中测量的实际温度值。结果表明，模型2的热阻隔性能要优于模型1。

Abstract: In order to analyze the fire resistance performance of the fire stopping system in UHVDC converter Station, key areas of fire stopping system from two converter stations (Model 1, 2) were selected. Under the hydrocarbon (HC) temperature rise curve condition, the heat transfer process of the fire stopping systems was simulated using ANSYS software. Key thermodynamic parameters including temperature fields, heat flux, and temperature gradients were analyzed. The temperature rise characteristics were further investigated through fire resistance tests and one-dimensional heat conduction model. The results demonstrate: Maximum heat flux density occurs at square steel (stud) locations due to their high thermal conductivity and conduction efficiency. The temperature at measurement point c1 on the backfire surface of Model 1 exceeds 180 ℃, failing to meet fire resistance rating requirements for fire stopping systems. Temperature rise rates at measurement points f1 and f2 are 0.047 1 ℃/s and 0.015 9 ℃/s respectively. Temperature values calculated using the one-dimensional heat conduction model are lower than actual measurements from fire tests. The results indicate that the thermal insulation performance of Model 2 is superior to that of Model 1.
