一、概述葛洲坝至上海500千伏超高压直流输电换流站水处理设备由西德BBC公司引进,用于可控硅阀运行中冷却水的处理和净化。冷却水的品质,是影响可控硅阀安全运行的重要因素。没有经过净化处理的天然水,其中含有许多杂质,是不允许直接进入
1. Overview The water treatment equipment of Gezhouba to Shanghai 500 kV UHV HVDC converter station was introduced by BBC, West Germany, for the treatment and purification of cooling water in the operation of thyristor valves. The quality of cooling water is an important factor affecting the safe operation of the thyristor valve. Unpurified natural water, which contains many impurities, is not allowed to enter directly
