飞机配电网络过流保护分析是验证飞机电网设计合理性、可靠性和安全性的重要内容之一。因此,主要对飞机配电网络过流保护分析方法进行了研究,并提出了一种特性曲线法。该特性曲线法基于导线载流特性曲线和电网保护装置过流保护动作特性曲线,分析方法简单、实用,可用于支持合格审定阶段飞机配电网络设计验证。
Analysis of over-current protection of aircraft distribution network is one of the important contents to verify the rationality, reliability and safety of aircraft network design. Therefore, this paper mainly studies on the analysis method of over-current protection in aircraft distribution network and proposes a characteristic curve method. The characteristic curve method is based on the current carrying characteristic curve and the overcurrent protection characteristic curve of the power network protection device. The analysis method is simple and practical and can be used to support the design verification of the aircraft distribution network during the certification phase.
