变电站消防系统典型二次回路解析和改进措施探索

Typical Secondary Circuit of Substation Fire Protection System and Improvement Measures

随着变电站消防工作管理要求的不断提升,站内运检人员熟练掌握变电站消防系统二次回路知识对于消防系统的日常运检和消缺极为重要。以某500 kV变电站为例,对消防二次回路进行解析,主要包括固定灭火装置控制回路和消防系统信号回路,并提出相关改进措施,为变电站消防系统二次回路可靠性提升提供解决方案,同时为变电站消防专业相关人员提供有价值的参考。

The elevating management requirements of substation fire protection magnifies the importance for the substation personnel to master the secondary circuit knowledge of substation fire protection system.Taking a 500 kV substation as an example,this paper analyzes the secondary circuit of substation fire protection,including control circuit of fixed fire extinguishing device and signal circuit of fire protection system.The paper may provide useful scheme for improving reliability of secondary circuit of substation fire protection system,and reference for related personnel of substation fire protection.
