摘  要:民航空管近台一般有自建的传输接入网络设备,用于承载台站上的甚高频、雷达信号到本场的传输,且台站传输接入设备多使用直流屏和一次电源设备供电,若两套直流屏可以实现并接供电,可以有效提高设备供电的可靠性,文章通过分析直流屏和一次电源设备供电原理,确认了两者并接供电的可行性,同时针对空管台站传输接入设备的直流电源接入方案提出一些优化建议。

Abstract: Civil aviation control stations generally have their own transmission access network equipment, which is used to carry the VHF and radar signals from the station to the field, and the station transmission access equipment mostly uses direct current panels and primary source equipment for power supply. If two sets of direct current panel can be connected in parallel, it can effectively improve the reliability of equipment power supply. This paper analyzes the power supply principle of DC screens and primary source equipment to confirm the feasibility of parallel power supply. Some optimization suggestions are put forward for the DC power supply access scheme of the station transmission access equipment.

Keywords: direct current panel; primary source; parallel rectifiers; transmission equipment

随着民航业务的迅猛发展、航班量持续增加,空中交通管理部门运行压力大幅增加,雷达、VHF等重要设备十几秒钟的中断就可能对管制业务产生重大的影响。特别是在边远台站,雷达、VHF等设备都需要接入传输设备再通过其传输至机场航管楼,传输设备一旦停止工作将直接导致雷达、VHF等设备的信号中断;加之边远台站由于其特殊的地理位置市电可靠性较差,为减少市电中断所造成的损失和影响,保障设备持续供电,台站传输和接入设备都配置有直流屏或UPS作為二次电源。以贵州空管分局龙洞堡雷达站为例,台站-48 V直流电源有一次电源模块和艾默生直流屏,若能使这2种电源相互组合构成冗余系统配置,将提高设备的供电保障能力。本文以民航贵州空管分局龙洞堡雷达站为例分析直流屏与一次电源模块并联的可行性。并提出相关优化建议。
