可编程控制器在相分段自动转换系统中的应用

The Appliction of Programmable Controller to Automatic Phase Conversion System

介绍一种电力机车带电通过相分段的自动转换系统。它用可编程序控制器ＯＭＲＯＮＣ２８Ｐ作为系统的核心，利用识别传感器采集机车信息，控制两台高压真空开关，使中性段带Ａ相或Ｂ相电，从而保证机车不断电通过相分段。系统投入试运行以来，工作正常，性能可靠。

Introduces an automatic phase conversion system.It uses programmable controller OMRON C28P as system center,it collects locomotive signsls by identification sensor,it controls two high voltage vacuum switches operation and the neutral circuit segment chares phase A or phase B,then the locomotive passes through the phase conversion with electriciry.The system operates regularly,the property is reliahle.
