运行与检修问答?

Gaoya dianqi, 1992
【问】什么叫AIO充气式开关柜? 【答】AIO是英文All in One的缩写,原意是将所有需要的配电装置（如母线、断路器、隔离开关、接地开关、电流和电压互感器等）组装在一个壳体内。这种开关柜是全封闭的,其外壳由角钢做成的框架和3mm厚的钢板焊接而成,内部与通常的开关柜一样分成几个隔室,每一隔室内按需要安装各种配电装置。柜内充以SF6气体,其工作压力视额定电压的不同约为120～150kPa。由于SF6气体的耐电压击穿强度约为空气的2.5～3倍,故每一隔室的尺寸可比通常开关柜的大为缩小 ...

不同着火位置对高压开关柜火灾影响的数值研究

Gaoya dianqi
基于流体动力学计算软件文中研究了不同着火位置对高压开关柜火灾的影响，分析了柜内温度场、无量纲温度因子、烟气分布及总热释放率火灾特征参量。计算结果表明，手车室发生火灾时最高温度低于电缆室或母线室最高温度，且不同着火位置下顶壁或侧壁无量纲温度因子差异明显，可用来进行早期火灾安全预警的诊断手段。烟气场和总热释放速率分布表明，电缆室和手车室着火时，其烟气可充满整个高压开关柜柜体，而母线室着火时烟气仅充满整个母线舱室。另外，电缆室火灾具有较大的总热释放率，因其相邻手车室可燃构件也被引燃进而释放更多的热量 ...
