无人值守热力站自动补水定压系统

Automatic Make-up Water Pressurization System in Unattended Substation

对无人值守热力站采用一级管网向二级管网自动补水定压方式应具备的条件及集中软化水站容量的确定进行了介绍。探讨了一级管网压力高于、低于、近似于二级管网定压值3种情况下的自动补水定压系统方案。

The preconditions of applying the automatic make-up water pressurization mode from primary circuit to secondary circuit in unattended substation and the determination of capacity of centralized softened water station are introduced. The schemes of the automatic make-up water pressurization system under the conditions that the pressure of primary circuit is higher, similar to or lower than pressure of secondary circuit are discussed.
