综合电子系统隔离与接地的前期设计问题研究

Research on Pre-design of Isolation and Grounding of Integrated Electrical System

综合电子系统的隔离和接地布局直接关系到系统研发的成败,因此,开展综合电子系统隔离和接地的前期设计研究是十分必要的。分别介绍了隔离和接地的基本原理、方法及其适用范围,并提出和归纳了综合电子系统隔离和接地前期设计的目的、原则、阶段及各阶段实施步骤。同时,优化了综合电子系统的系统级、子系统级、部件级的隔离和接地前期设计,为系统研发奠定了坚实的基础,且避免了研制后期由于此类问题引起的系统结构更改。

Isolation and grounding layout of the integrated electric system is directly related success or failure of research and development of the system.Therefore,researching the pre-design of isolation and grounding for integrated electric system is necessary.The basic principles,methods and applicable scopes of isolation and grounding are introduced respectively;and the purpose,criteria,stages and implementing procedures in each stage are proposed and summed up.In addition,optimizing pre-design of isolation and grounding in system level,subsystem level and component level is beneficial to establish solid foundation for research and development of the system,and avoid structural revision of the system in post development stage.
