The Pressure Loss Calculation Method and Application of Portable Fire Extinguishing Equipment for Power System

摘要

Wildfire nearby transmission has posed a serious threat on power system. Research on portable fire extinguishing equipment hasimportantsignificance to massive wildfire emergency handling. Structure of the water transfer system of the portable fire extinguishing equipmentis analysed. Pressure lossforms of the equipment are elaborated. Basing onactual instance of the water transfer system, a calculation method of pressure loss for long-distance and high-lift transmission is proposed. With the result of the test and CFD simulation, the efficiency and the practicability of the method is verified. A conclusionthat transportation distance reaches close to 3000 meterswhilehead reaches 500 meters is drawn. Finally, the application of the portable fire extinguishing equipment in fire prevention of power transmission line results show thatmassive wildfires can be extinguished quickly. By using the equipment, electric power company’s ability of resisting wildfires has gained remarkable improvement.
