摘要
通过对M310核电机组电气厂房冷冻水系统的风冷机组控制系统及供电方式和冷冻水循环泵供电方式的分析,结合福清核电1~4号机组调试和运行期间风冷机组的运行经验反馈,提出了风冷机组和冷冻水循环泵现有的供电方式的不足之处,并给出了改进建议。通过对改进前后的运行方式和安全可靠性进行深入分析探讨,改进后的供电方式可使冷冻水循环泵和风冷机组具有更高的安全可靠性。
By analyzing the power supply mode and control system of DEL air-cooled chiller and the power supply mode of chilled water pump for M310 unit,some disadvantages and suggestions are given about the power supply mode of air-cooled chiller and chilled water circulating pump combined with the operation experience of 1~4 units of Fuqing nuclear power plant during commissioning and operation.Through deep analysis and discussion on the operation mode and safe reliability before and after improvement,the improvement can make the chilled water pump and the air-cooled unit having higher safety and reliability.
