根据刚性模型风洞测压试验所得数据,研究了不同的周边干扰条件下柜体表面平均风压系数的变化规律,对比分析了不同柜体间距时干扰效应的变化情况。研究结果表明:干扰煤气柜位于柜体的正前方时,柜体迎风面平均风压系数显著减小;干扰煤气柜位于柜体的正后方时,柜体背风面平均风压系数会增大;两煤气柜相互平行时,柜体背风面平均风压系数会减小;柜体间距会对干扰效应产生影响,干扰效应随着柜体间距的变化而发生变化;在迎风面与侧风面,规范值有较高的安全储备;而在背风面,其安全储备略有不足。
According to the data obtained from the wind tunnel pressure test of the rigid model, the variation rules of average wind pressure coefficient on the surface of the cabinet under different ambient interference conditions are studied, and the variation of the interference effect when different cabinet spacings are compared is analyzed. The results show that when the interference gas tank is located in front of the cabinet, the average wind pressure coefficient on the windward side of the cabinet is significantly reduced. When the interference gas tank is directly behind the cabinet, the average wind pressure coefficient on the leeward side of the cabinet will increase. When the two gas cabinets are parallel to each other, the average wind pressure coefficient of the leeward side of the cabinet will be reduced; the spacing of the cabinets will have an impact on the interference effect, and the interference effect will vary with the spacing of the cabinets; on the windward side and the side winds, The normative value has a higher safety reserve; while on the leeward side, its safety reserve is slightly deficient.
