设计完成基本测试方法

进而又提出改进的相对相位时间差测试方法。实验证明:该方法较传统方法有着成本低、精度高及实现方便等优点

并克服了一般的测试方法中电路设计复杂、受环境影响大和不便于体积分数补偿等问题

在高压工控现场有着广泛的适用性和较高的应用价值。

Abstract

An advanced testing method for trace gas volume fraction

based on the ultrasonic theory and CPLD technology is described.It is used in gas insulated switch（GIS）-site.It can help to design and accomplish a primary test method.To take a further step

an advice is given on improved method of relative phase lag method

on the basic of analyzing the calculation formula for volume fraction of binary gas.Experimental results show that the method has the advantage of low cost

high precision and easy to operate than traditional way

and overcomes some troubles in normal test such as complex circuit design

environmental influences

awkward compensation density.Due to these advantages

this method has high value and wide application in industrial control fields.
