摘　　要：阐述了机械设备Y-△面降压起动系统方式的工作原理及工作特性,对Y-△起动系统中常被忽视的电气线路和设备元件选择中的问题进行了分析,弥补了现有Y-△降压起动系统的不足,确保了机械设备安全可靠地运行。The essay expounds the mechanistic working pricinple and property of the starting system of Y - △ which are in the process of decreasing pressure. In the starting system, the essay analyses the problem often overlooked that is about the selection of electrical circuits and machine components. Furthermore, in the process of reducing pressure, if makes up for many defects of the avilable starting system of Y - △ . To depend on the analysis the relibility and safety machine can be ensured.
