Ammonia Substation Secondary Lightning Protection And Grounding Technology Research

With the construction and development of the socialist modernization, The building gradually expanding scale。The growing use of variety of electrical equipment, Especially the popularity of computer network information technology, Building more and more electrical equipment using a variety of information technology。In China every year, many of the buildings inside the electrical equipment due to lightning damage and it Cause great losses。 Lightning protection design is particularly important。In this paper, we research and discuss the formation of lightning and some of their characteristics。Analyze and understand the grounding resistance and Ray voltage parameter calculation methods and principles of invasive of wave numerical and lightning protection range。Then introduced based on the composition and structure of the integrated lightning protection system of the external lightning protection system lightning protection and internal lightning。The emphases of our research is the protection principle of the grounding device laying and antiseptic principle and power automation systems and SPD surge protection module and solenoid theoretical basis the shielding principle and lightning invasion wave and over-voltage value。at last, we use the paper’s date and conclusion to design the substation and the main control room to prevent lightning attacks。Finally, the external lightning protection system and internal lightning protection systems and the main control room for Ammonia substation preliminary mine design。 Especially the secondary circuit designed lightning protection system。Start from the synthesis substation location Analysis and Discussion, Through the selection of a lightning rod, grounding system design, the shielding effect of the Application of equipotential connection design and SPD selection to design The Lightning Design of Ammonia Substation。...
