摘　　要：针对高温阀用电磁机构(EM-HTV)应用环境温度高(约200℃)的特点,首先采用电磁场及温度场分析方法,研究了EM-HTV的电磁场损耗分布、温度场分布。随后,提出了一种“线圈分段+段间导热环+外壳散热板”的新型结构,基于正交试验原理对所提出结构中的关键尺寸进行了优化设计,对现有电磁机构进行了改进,并对提出的新结构进行温升试验验证,试验数据与仿真数据的误差在合理范围内,证明了电磁场及温度场分析方法应用于线圈温升分析的可行性。最后,研究了新型结构高温阀用电磁机构的温度分布,发现最高温度由优化前的278.29℃下降至241.23℃,温度降低了约13.32%,低温区域明显增多,满足可靠运行温升要求。此外,所提出的新型结构具有绕线方便、便于排除故障、易模块化加工以及易对现有产品改造的优点。According to the characteristics of high temperature(about 200℃)of electromagnetic mechanism for high temperature valve(EM-HTV),firstly,the electromagnetic field loss distribution and temperature field distribution of EM-HTV are studied by using electromagnetic field and temperature field analysis method.Then,a novel structure of“coil grading with interstage heat conduction ring and shell cooling plate”is proposed.Based on the principle of orthogonal experiment,the key dimensions of the proposed structure are optimized.The existing electromagnetic mechanism is improved,and the new structure is verified by temperature rise test.The error between the test data and the simulation data is within a reasonable range,which proves the feasibility of applying the electromagnetic field and temperature field analysis method to the coil temperature rise analysis.Finally,the temperature distribution of the high temperature electromagnetic drive mechanism of the new structure is studied,and it is found that the maximum temperature decreases from 278.29℃by about 13.32%to 241.23℃,and the low temperature area increases obviously,which can meet the requirement of reliable operation temperature rise.In addition,the proposed structure has the advantages of convenient winding and easy troubleshooting,modular processing and modification of existing products.
