精确检测阀组旁路开关的位置是云广直流控制系统阀组触发脉冲与阀组旁路开关成功配合的关键。阐述了在解锁串联双阀组中第二个阀组期间使阀组旁路开关位置与阀组触发脉冲相配合的控制过程,分析了阀组旁路开关位置判别功能及其检测回路,当前回路设计的不合理性及其可能给运行维护带来的安全隐患,并提出了解决方法。此方法已成功应用到±800 kV糯扎渡直流工程中。

The accurate position detection of the valve group bypass switch is the key to ensure the successful cooperation of the control firing pulse and the action of vavle group bypass switch in Yunnan-Gruangdong.Introducing the control process to make the valve group bypass switch position cooperating with the control firing pulse during the second valve group deblocking,this paper analyzes the position checkback function of valve group bypass switch and relevant detection circuit,pointing out that there is such a shortcoming in the present design for valve group bypass switch that could cause failures in the valve group operation and maintenance,and proposing a resolution for that problem.That proposed resolution has been applied to Nuozhadu ±800 kV DC project.
