航空航天.飞行器电气系统的特性

[中文适用范围]： 本国际标准规定了向安装在飞机上的用电设备终端供电的电力特性。 它旨在支持设计用于在各种新型民用飞机应用上接受电力的用户设备的接口定义，例如通过技术标准订单 (TSO) 认证流程认证的应用。 对于针对单一应用或特定军事应用的设备可能不希望遵循本国际标准，因为与多重应用相关的处罚。 本文件还试图提供这些要求的制定背景，这可能对那些设计和/或集成现代飞机电气系统的人有用。 电力的输送质量是电源、配电和用户设备综合特性的结果。 虽然仅具体定义了用户设备限制，但确定了关键源和分发设备接口的背景，以支持整个系统的开发。 考虑了小型和大型运输机上可能存在的各种电源类型和分布参数。 考虑的来源包括物理旋转和静态类型，提供在飞机上或作为地面支持设备的一部分。 所涉及的配电电压为： 标称 14 V、28 V 和 42 V 直流电； ——标称 26 V 交流电，400 Hz，单相； ——标称 115/200 V rms 和 230/400 V rms 交流，单相和三相，标称 400 Hz 恒定频率 (CF) 或包括 400 Hz 的可变频率 (VF) 范围。 [外文原描述]： ISO 1540:2006 specifies the characteristics of electrical power supplied to the terminals of electrical utilization equipment installed in an aircraft. It is intended to support the interface definition for user equipment designed to accept electrical power on a variety of new civil aircraft applications, such as those certified via the Technical Standard Order (TSO) certification process. It might not be desirable for equipment targeted to a single application or specific military application to follow ISO 1540:2006 because of the penalties associated with multi-application. ISO 1540:2006 also attempts to provide background to the development of these requirements that may be useful to those designing and/or integrating modern aircraft electrical systems. The delivered quality of this electrical power is a result of the combined characteristics of the electrical power source, distribution and user equipment. While only user equipment restrictions are specifically defined, background to key source and distribution equipment interfaces are identified in order to support development of the overall system. A wide variety of electrical supply types and distribution parameters have been considered, as may be found on both small and large transport aircraft. Sources considered include physically rotating and static types, provided either on-aircraft, or as part of the ground support equipment. Distribution voltages addressed are nominal 14 V, 28 V and 42 V d.c.; nominal 26 V a.c., 400 Hz, one-phase; nominal 115/200 V rms and 230/400 V rms a.c., both one-phase and three-phase, at either a nominal 400 Hz constant frequency (CF), or over a variable frequency (VF) range which includes 400 Hz.
