Research on Performance Evaluation Method of Compressed Air Foam Fire Extinguishing System in UHV Converter Station

In order to ensure the safety and reliability of fixed compressed air foam system (CAFS) used in UHV converter station, the performance evaluation method of CAFS was studied, so as to ensure the stability of electric power transportation. Based on the analysis of the structure and working principle of the fixed CAFS and the relevant standards at home and abroad, the performance evaluation method of fixed CAFS is presented in combination with the operating environment. The main parameters affecting the performance of the system are determined by the test. The analysis and test show that the evaluation research of fixed CAFS should focus on the pressure, flow and performance parameters of generating device, pressure loss and transmission speed of transmission pipe network, and foam spray performance of spray device.
