摘要
航空安全一直是航空行业发展中的重要课题,降低航空电气系统的火灾危险性可以有效提高飞机的飞行可靠性。首先分析航空电路特点,其电源相比地面来说,电压大小为110 V,频率为400 Hz;其次用Matlab/Similunk仿真模块建立Cassie电弧故障模型,对纯阻性负载和阻感性负载进行串联电路仿真;最后得出时域电流、电压波形,并进行特征分析。
Aviation safety has always been an important issue in the development of the aviation industry.Reducing the fire hazard of aviation electrical systems can effectively improve the flight reliability of aircraft.First,analyze the characteristics of aeronautical circuits.Compared with the ground,the power supply has a voltage of 110 V and a frequency of 400 Hz;secondly,a Cassie arc fault model is established with the Matlab/Similunk simulation module,and the pure resistive load and the resistive inductive load are connected in series.Simulation;finally get the time-domain current and voltage waveforms,and perform characteristic analysis.
