摘要
为了降低特高压换流站发生火灾所带来的损失,研发一种可产生匀泡、稳流、高动能泡沫的固定式CAFS装置,并将其应用到特高压换流站中。建立特高压换流站输电模型,在该模型下分析固定式CAFS装置的应用要求,从而确定装置的安装位置。分别从进水、泡沫比例混合、储存和自动调压控制等多个方面,选择固定式CAFS装置组件型号。连接装置组件,并将配制好的灭火剂注入其中,安装在特高压换流站指定位置,实现固定式CAFS装置的设计与应用。实验结果表明,该装置能够降低火灾的受灾面积和持续时间,即在应用性能方面具有明显优势。
In order to reduce the loss caused by fire in UHV converter station,a fixed CAFS device which can generate foam with uniform foam,steady current and high kinetic energy was developed and applied to UHV converter station.The transmission model of UHV converter station is established,and the application requirements of fixed CAFS device are analyzed under this model,so as to determine the installation position of the device.The model of fixed CAFS device components is selected from the aspects of water inflow,foam proportional mixing,storage and automatic pressure regulation control.Choose fire extinguishing agent and calculate the mixing ratio of foam raw materials to realize the preparation of foam fire extinguishing agent.Finally,the device components are connected,and the prepared extinguishing agent is injected into them.The design and application of the fixed CAFS device are realized by installing at the designated position of UHV converter station.Compared with the traditional fire extinguishing device,it is found that the application of fixed CAFS device in UHV converter station can reduce the affected area and duration of fire,that is,it has obvious advantages in application performance.
