摘　　要：介绍换流站阀冷水冷系统和阀冷控制系统基本原理。分析深圳换流站、肇庆换流站和广州换流站阀冷系统普遍存在的一些关键薄弱环节,如传感器冗余问题,主泵薄弱环节等,针对存在的薄弱环节提出了改进措施,例如改造传感器的电源,采用冗余传感器,对其他换流站具有积极的借鉴意义。Basic principle of valve cooling system and valve cooling control syetem is introduced. Some key weaknesses is found at Bao’an Converter Station, at Zhaoqing Converter Station and at Gangzhuo Converter Station, for example redundant problem of the sensor, weaknesses of the main pump et al. In view of existence weaknesses, some corrective measure such as using redundant sensor, transforming the sensor power supply etc is put forward. These can be a reference for other converter stations.
