GJB 181B-2012《飞机供电特性》规定了飞机电气系统中用电设备输入端的供电特性,同时也对采用本特性供电的用电设备给出了相关要求,本标准适用于飞机供电系统、外部电源与用电设备之间的协调。
GJB 181B-2012不仅是飞机供电系统的顶层标准,更是供电系统和用电设备的接口标准,涉及到飞机电气系统的各个方面。
GJB 181B-2012设范围、引用文件、术语和定义、一般要求、详细要求和应用指南等6章。首先规定了飞机电气系统的术语,对飞机电气系统、工作状态和特性参数等常用术语给出明确的定义,统一了概念;然后,从飞机电气系统涉及的飞机供电系统、用电设备、外部电源和试验等四个方面提出通用性要求;进一步对分别各种供电类型的特性作出了详细规定,并从对供电的影响方面提出了对用电设备的要求。
GJB 181B-2012规定的供电类型包括:
a)115V、400Hz三相交流;
b)115V、360Hz~800Hz三相交流;
c)220V、50Hz单相交流;
d)28V直流;
e)270V直流。
基本覆盖了目前飞机电气系统设计中涉及到的主要供电类型,其中220V、50Hz单相交流供电系统仅用于商用货架产品。
GJB 181B-2012与GJB 181A-2003相比,主要修订内容如下:
a)增加了一些新的术语和定义,如电流调制、功率因数、脉冲负载、非线性负载、频率变化率等;
b)交流变频供电系统的频率范围由320 Hz~640 Hz修订为360 Hz~800 Hz,更改了电压瞬变特性,增加了频率变化率等要求;
c)增加了交流单相220 V、50 Hz供电特性要求;
d)增加并完善了影响供电系统的相关负载特性要求。
