航空电气保护器在飞机除冰系统上的应用

Application of Aviation Electrical Protection in Aircraft Deicing System

针对目前飞机除冰系统大电流三相用电设备存在传统保护器件控制方式落后、电流整定值大、保护时间长等问题,引进了航空短路保护器和航空断相保护器作为飞机除冰系统保护和控制器件。实践表明,改进后的保护器控制方式先进、能有效降低电流整定值、提高保护灵敏度,可满足飞机除冰系统三相大功率用电设备的电气要求。

According to heavy current, backward control method and long protection time of three phase circuit breaker on aircraft deicing system, a solution based on short-circuit protector and open-phase protector was presented. The experimental result shows that the protectors have advanced control method, low current, high sensitivity, and can protect three phase high power equipment.
