飞机的电源系统是飞机上重要的功能系统之一,其作用是为整架飞机提供通讯、导航及操纵系统控制所需电能。飞机上能产生电能的设备组合(包括电源和电源调节、电源控制和电源保护设备)叫作飞机电源系统,电源系统有主电源、辅助电源、应急电源和二次电源。飞机上用来传输、分配、转换和控制电能的导线和设备,称为飞机配电系统或者飞机电网系统。本文简述了通用飞机电源系统结构组成优点及针对SR20机型电源系统原理的介绍,重点是针对其在使用过程中出现的故障进行了原因分析和处理流程,并提出了在电源系统维护工作中的注意事项。
The aircraft’s power system is one of the most important functional systems on the aircraft. Its role is to provide the entire aircraft with the power needed for communication, navigation and control of the system. The combination of devices (including power and power conditioning, power control, and power protection devices) on the airplane that generate electricity are called aircraft power systems that have primary, secondary, emergency, and secondary power supplies. The wires and equipment used to transport, distribute, convert and control electrical energy on an aircraft are called aircraft power distribution systems or aircraft power grid systems. This article describes the general aircraft power system structure and the advantages of SR20 model power system for the introduction of the principle, the focus is on its use in the process of fault analysis and processing flow, and proposed in the power system maintenance work Precautions.
