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。
Currently, communications, navigation station grounding device is more complex, different nature, the type of grounding is often mixed with more common. Due to site constraints, cost savings and system special needs and other factors, resulting in communications, navigation and other construction projects mixed grounding or equipotential grounding to become the mainstream, but the most problems, soft faults, frequent hard faults, seriously affecting the normal system jobs. This article introduces the application and development of grounding technology, analyzes the nature of grounding, and studies the advantages and disadvantages of grounding methods and forms such as floating grounding, independent grounding, common grounding and hybrid grounding, clarifying the requirements of grounding system of communication and navigation stations, Such as station grounding design and maintenance to provide help and reference.
