摘要
控制棒水压驱动技术是清华大学核能与新能源技术研究院具有自主知识产权的一项新型发明专利技术,组合阀属于该项技术的关键部件。组合阀由3个直动电磁阀组成,电磁阀的性能直接影响组合阀的性能,从而影响控制棒水压驱动技术的运行性能。本工作运用ANSYS电磁场分析软件,变化输入电流,对直动电磁阀的8种设计结构进行了电磁场特性分析,并予以实验验证。分析结果表明:在电流增大情况下,电磁力增加,且平角铁芯吸合面电磁阀的电磁力增加较快;铁芯之间的环形密封结构对不同吸合面的电磁阀有不同的效果;分段导磁材料结构对电磁力增幅有较大的促进作用。
Hydraulic control rod drive technology(HCRDT) is a newly invented patent with Institute of Nuclear and New Energy Technology of Tsinghua University which owns HCRDT's independent intellectual property rights.The integrated valve which is made up of three direct action solenoid valves is the key part of this technology,so the performance of the solenoid valve directly affects the function of the integrated valve and the HCRDT.The electromagnetic field of 8 types of the direct action solenoid valve was analyzed using the ANSYS software with various currents,the results of which were validated by experiments.It shows that the magnetic force increases with the increasing current and the magnetic force of the solenoid valve with straight-angel armatures increases much faster.Furthermore,different shaped interfaces of the annular airproofing structure between armatures lead to different results.At last,the subsection of magnetic material accelerates the magnetic force sharply.
