摘　　要：仪表着陆系统(ILS)是航空器起飞、降落过程中提供下滑道、航向道等重要引导信号的导航设备,珠海空管站05号和23号仪表着陆系统设备为珠海机场航班安全进近和着陆扮演着至关重要的角色,其机房供配电直接关系到民航空管安全。结合仪表着陆系统05号下滑台机房零地电压偏高问题,探究零地电压产生的原因、零地电压过高的影响、排查手段及防控措施,为解决类似问题提供参考。The instrument landing system(ILS)is a navigation equipment that provides important guidance signals such as glide slope and localizer during aircraft takeoff and landing.The ILS equipment at Zhuhai ATC Station No.05 and No.23 plays a crucial role in the safe approach and landing of flights at Zhuhai Airport.The power supply and distribution in the equipment room are directly related to the safety of civil aviation ATC.This paper combines the problem of high zero ground voltage in the ILS glide slope machine room at No.05,to explore the causes of zero to ground voltage,the impact of high zero to ground voltage,troubleshooting methods and prevention and control measures,so as to provide reference for solving similar problems.
