DOVR VRB-52D设备安装过程中电缆的匹配方法

Matching method of cable in the installation process of DOVR VRB-52D equipment

目的 :掌握AWA VRB-52D设备的安装步骤及测试方法。方法 :以中小机场全向信标机的安装过程为例,将传输线理论应用到电缆的修剪和匹配当中,利用失量电压表测试数据,根据数据结合史密斯阻抗圆图能够快速完成多根电缆的修剪和匹配,满足设备的正常开机条件以及达到最后天线辐射信号符合飞行校验标准。结果 :理论数据和实际结论相符,开机正常,满足设备工作要求。结论 :中小机场的专业技术人员能够结合设备手册和失量电压表完成设备的快速安装调式,为今后的日常维护提供指导。

Objective:to master the installation steps and test method of AWAVRB52 D equipment.Method:the installation process of small and medium-sized airports omnidirectional beacon machine as an example,the tr ansmission line theory is applied to the cable pruning and matching,the loss of voltage meter test data,acc ording to the data with the Smith chart to quickly complete the multi cable pruning and matching,meet the n ormal conditions of the equipment and to signal the end of antenna radiation in accordance with the flight calibration standard.Results:the theoretical data and actual results, boot properly, meet the equipment req uirements.Conclusion:the professional and technical personnel of small and medium sized airports to quickl y install mode combined with equipment manual and loss voltage meter complete equipment daily maintenance,t o provide guidance for the future.
