ATS矩阵开关自检研究

The Study of Self-test for Matrix Switch of ATS

矩阵开关作为一种最灵活的开关拓扑结构,在ATS系统中得到了广泛的应用,也是ATS自检的关键部件之一。受限于自身结构特性,矩阵开关可靠性相对较低,且一般不自带自检功能。依据ATS中矩阵开关的特性、常见故障及其自检目的,研究和分析了矩阵开关自检的内容,并针对某型ATS中的双线矩阵,设计了不同的自检方法,通过分析和对比,可为其他ATS矩阵开关自检方法设计提供参考。

As the most flexible switching topology, Matrix switch has been widely used in ATS and also is one of the key components of self-test for ATS. Limited by structural character- istics, its reliability is relatively low and generally does not have their own self-test function. According to the characteristics, common faults and self-test purposes of the matrix switch of ATS, the self-test contents of the matrix switch are studied and analyzed. Different self-test programs are designed for 2-Wire Matrix Switch of a certain type of ATS and providing reference to other self-test program designs for matrix switch of ATS with programs analysis and comparisons.
