摘要:

霍尔传感器是特高压直流输电系统中旁路断路器特有的分合闸位置传感元件,在同一极中单阀组运行状态下解锁另一阀组的过程中起到重要作用。本文分析了一起由于霍尔传感器故障造成阀组解锁不成功的案例,提出对霍尔传感器进行定期校验的改进建议。

Abstract:

Hall sensor is the specific switchposition sensor of bypass-switch in UHV system, and it is important to the process of deblock the single valve group while the anothervalve group is operating in the same pole. In this paper a valve group deblock failure caused by the Hall sensor fault is analized, and the improvement suggestions are proposed to regularly test on Hall sensor.

Key words: UHVDC, Hall sensor, bypass-switch, deblock failed
