雷达阵地地线误接分析及其改造方案

Analysis of Grounding Misconnection of Radar Positions and Its Reform Project

针对某雷达装备普遍存在的地线误接问题,运用电磁暂态分析程序(ATP-EMTP)仿真分析了地线误接对雷达装备造成的危害,并根据一点接地原则和铺设联合地网方法,提出了两种合理可行的改进措施.这两种措施能够保证天线车与雷达方舱之间的暂态电位差峰值小于设备的耐压值,对某雷达装备的防雷与接地安全具有重要的现实指导意义.

Concerning for the common grounding miscormection of a certain radar equipment, this paper simulates and analyzes the harm of grounding misconnection to the radar equipment by using the alternative transients program-electromagnetic transients program （ATP-EMTP）, and proposes two sorts of properly feasible improvement measures in terms of the principle of one point to grounding and the method of laying the joint grounding network, which can guarantee that the transient potential difference peak between antenna vehicle and radar shelter is lower than the withstand voltage of the equipment, and be of instructive significance to the lighting protection and grounding safety of the radar equipment.
