Based on the Relationship between the Conductivity and the Resin Treatment Time of a Valve-cooled Deionized Self-circulation System

高压直流阀冷却系统是高压直流输电工程重要的辅助系统,是高压直流输电系统安全、稳定运行的重要设备。本文通过模拟某高压直流输电阀冷项目现场离子交换器去离子自循环系统的运行,检验离子交换器去离子自循环系统是否能够正常工作,确定自循环补水系统通过调制电导率为2000μS/cm的市政自来水处理到10μS/cm所需要的时间,为离子交换器去离子自循环系统控制逻辑的定值设定提供了一定的依据。

The high voltage DC valve cooling system is an important auxiliary system for HVDC transmission engineering and an important equipment for safe and stable operation of HVDC transmission system. In this paper, by simulating the operation of the ion exchange deionization self-circulation system of a high-voltage DC transmission valve cold project site, it was verified whether the ion-exchanger deionization self-circulation system can work normally, and the self-circulating hydration system was determined to have a modulation conductivity of 2000 μS/cm. The time required for the municipal tap water to be processed to 10 μS/cm provides a basis for the setting of the control logic of the ion exchange deionization self-circulation system.
