摘　　要：通过对四边形特性继电器在克服短路点过渡电阻的影响和躲过负荷阻抗等方面优良特性的分析,研究了四边形特性阻抗继电器的实现方法和特性。并介绍了虚拟仪器的概念,以图形化编程软件LabVIEW为软件开发平台,开发的四边形特性继电器,具有界面友好、操作简单和较优良的抗过渡电阻和躲负荷的能力等优点,应用于实验室中取得了良好的效果。The realizable method and its specific property of impedance relay of quadrangle characteristic are studied. Impedance relay of quadrangle characteristic are discussed initially, aiming at analysis of the excellent specific properties that impedance relay of quadrangle characteristic helps to overcome the influence of transition resistance and load resistance. And the concept of virtual instruments is introduced, the system of quadrangle characteristic of relay based on LabVIEW graphical programming environment is developed, This system is excellent for friendly interface and simple operation and overcoming the influence of transition resistance and load resistance. The system has got a good verification in the lab.
