| 摘要: |
| 为了提高气体绝缘全封闭组合电器（GIS）的运行可靠性，结合GIS的构造特点与控制要求，设计了基于可编程控制器（PLC）的GIS控制系统。该控制系统以PLC为逻辑控制核心，采用梯形图语言编写逻辑控制程序，依据GIS单元间隔及其构成组件的逻辑控制关系对所采集的GIS各个状态参量与控制信号进行逻辑处理，替代GIS控制系统中原有的一系列逻辑控制硬连接，实现GIS控制由逻辑硬连接控制向逻辑软连接控制的转变，进而实现GIS控制系统的智能升级与构造优化。研究表明，基于PLC的控制系统作为GIS控制系统具有良好的应用效果。 |

| Abstract: |
| To enhance its operating performance，a PLC-based control system is designed for GIS（Gas-Insulated Switchgear） according to its contractual features and control requirements. The logic control core，which is programmed with the ladder diagram，processes the acquired binary signals and control signals of GIS. The logic control function，which is implemented originally by hardware，is now realized by software to enhance its intelligent control and structure optimization. Research indicates that，the PLC-based control system has excellent application prospect for GIS. |
