通信导航台站接地技术与方法研究

Research of the grounding technology and grounding scheme for the Communications and Navigation Station

目前通信、导航台站接地装置比较复杂,不同性质、类型的接地往往混合共用情况较多。因场地限制、节约经费和系统特殊需要等因素,导致通信、导航等工程建设中混合接地或等电位接地成为主流,但问题出现的最多,软故障、硬故障频发,严重影响着系统的正常工作。本文介绍接地技术的应用发展,分析接地本质类型,研究浮点接地、独立接地、共用接地、混合接地等接地方法与形式的优缺点,理清通信、导航台站接地系统要求,为通信、导航等台站接地设计与维护等提供帮助及参考。

The communications and navigation station earthing device is more complex and different in nature than other types of grounding and often requires more mixed or hybrid solutions. There are always space limitations and budget constraints but in the communications,navigation and other projects in the construction of hybrid grounding and Equipotential Grounding Systems into the mainstream, the main problem is frequent failure of software and hardware. This paper introduces the application of mixed grounding technology development and analyses the advantages and disadvantages of floating earth,independent earth and common grounding. It＇s based on the requirements of the communication,navigation station grounding system to offer help as well as a general reference for communications,navigation and grounding design of other stations and maintenance and so on.
