电动执行器在联合循环气体发电厂提供安全功能
- Industry:Energetyka konwencjonalna
- Kategoria：Elektrycznenapędyumatury
- produkty：CVL，CVQ
Summary
DIDCOT B上安装和委托的CVL线性控制阀执行器是一个有效的合并循环气体发电厂，净容量约为1,440 MW。满足一百万家庭需求的权力。
概述
Didcot B power station is a combined cycle gas power plant that has supplied electricity to the National Grid since 1997.
挑战
Existing hydraulic actuators controlled the supply of the spray water that is used as an emergency quench in the condensers should the steam turbine trip. An emergency quench within a condenser reduces temperatures and controls gases and is as such a key safety function within a natural gas power plant. These hydraulic actuators needed to be updated to an electric solution as part of a wider modernisation project.
解决方案
CVA范围内的执行器的选择确保了紧急淬火系统内对控制阀的高度准确和响应性的连续调节。

Customer Benefits
This installation was part of a wider project at Didcot B to improve equipment reliability and obsolescence/future-proof planning.
CVL执行器在EX环境中提供精确而可靠的控制。它们也对IP68进行防水，这对于此应用至关重要。终端室被密封，大大降低了进水的机会。
DIDCOT B电站在涡轮机平稳运行的这一基本部分的旋转式选择表明，有效，可靠的驱动技术的重要性。
The CVL units replaced existing hydraulic actuators and now provide improved reliability and reduced maintenance costs.
