一种面向运载火箭电气系统的模块化分级供配电体制

Modular Hierarchical Power Supply and Distribution System for Electrical System of Launch Vehicle

针对运载火箭电气系统供电电缆规模偏大、拓扑复杂、易引发跨级供电潜通路等问题,提出了一种电气系统模块化分级供配电方案。将运载火箭各级分别规划为一个独立的供配电单元,供配电单元内采用通用化设计,实现对内部负载的一体化供电;供配电单元间、电气系统箭地间、供电母线间电气隔离,以避免供配电单元间的电气耦合,彻底消除级间潜通路,降低设计难度,最终使得运载火箭电气系统供配电体制具备系统层级模块化特征和供配电单元即插即用能力,为未来电气系统供配电架构的标准化设计和运载火箭分级测试提供技术基础。

A modular hierarchical power supply and distribution method is proposed for electrical system of launch vehicles in order to avoid large scale power supply cable,complex topology and potential path.Each stage of electrical system is planned as an independent power supply and distribution unit,and the integrated power supply and distribution framework is realized in the unit.Electrical isolation is designed among different power supply and distribution units and ground equipment to prevent the electrical coupling and potential circle path and reduce the system complexity.The power and distribution system has the advantage of modularization in system level and the plug and play with units,which provides a technical basis for the standardized design of the power supply and distribution structure of the future electrical system and hierarchical test of the launch vehicle.
