摘　　要：飞行器综合测试主要对电气系统各功能及接口的协调性和匹配性进行全面的综合检查;测试设备接地不正确,可能干扰地面设备和飞行器产品,甚至将危险电压引到飞行器上;为实现综合测试可靠安全接地,简要介绍接地的概念和作用,说明良好的接地是保护人身安全、保障电气系统正常运行、防止雷击和静电危害的有效方法;结合飞行器综合测试系统功能和组成,将系统划分为供电设备、测试设备和控制设备,分析了各类设备的接地原则和方法,即确保安全和兼顾电磁兼容特性,测试设备接口不能干扰飞行器上产品正常工作,最后提出测试设备接地安全保证措施,包括试验前,对场地和设备接地的检查、设备接地与供电要求、操作规定、连接前测试等方面,为航天项目产品研制提供参考。The integrated test system on aircraft is used to comprehensive examinations about any function coordination and interfaces compatibility.If the groundings of the equipments are false,equipments on the ground and products on the aircraft are disturbed,even a hazard voltage imports the aircraft.In order to achieve reliability and safety grounding,the functions of grounding was introduced.the suitability grounding is the effective way of protecting the personal safety,ensuring the equipment normally work and preventing the lightning strike and electrostatic discharge damage.Combining the functions and components of the integrated test system,the system was divided to power equipment,measure equipment and control equipment.The grounding principles and methods of the test equipments were analyzed.That is ensuring safety and considering EMC characteristic,and the interface of the measure equipment can not disturb the normally work of products.Finally,the guaranteed safety measures of grounding were proposed,including examining the field and equipment grounding,the demand of the equipment grounding and power,operation regulation and so on.This paper is a useful reference for the manufactures of the aircraft products.
