浮力式低温液位计的设计原理及运行工况分析

Design principles and operating conditions analysis of buoyancy cryogenic liquid level meter

全超导磁约束核聚变实验装置EAST的13对磁体电流引线全部采用高温超导(HTS)。为保证其安全运行,特为其液氮储槽设计制作了浮力式液位计。经过几轮物理实验,证明这种深冷液位计能较准确地监视HTS电流引线液氮储槽的液面,从而保证HTS电流引线的安全运行。文中介绍浮力式深冷液位计的设计原理及其运行工况。

HTS current leads as magnet power leads are used for the whole superconducting magnetic confinement fusion experimental device EAST. The buoyancy liquid level meter in the liquid nitrogen tank is designed specially to ensure its safe operation. After several rounds of physical experiments, it is proved that the cryogenic liquid level meter can more accurately monitor the level of the HTS current leads liquid nitrogen tank. This article describes design principles and operating conditions of the liquid level meter.
