摘要
在对常用Y-△降压起动电路进行分析的基础上,采用PLC对星形、三角形接触器主触点接线及控制电路进行改进设计,实际运转证明效果良好。
Based on the analysis of commonly-used Y-△ reduced-voltage starting circuit, PLC is adopted for the improved design of main contact wiring and control circuit of star and triangle contactors. The practical operation indicates a good result.
