126kV真空灭弧室2/3匝纵磁触头磁场分析及优化
Analysis and Optimization of Axial Magnetic Field Characteristics of a 2/3 Tune Coil-type Contacts for 126 kV Vacuum Interrupter
摘要
Abstract
For determining the optimum design parameters of a 2/3 turn coil-type contact with axial magnetic field (AMF) for a 126 kV vacuum interrupter,the combined experimental design-finite element calculation-statistical analysis method is adopted to conduct single factor analysis and orthogonal regression analysis on AMF characteristics of the contact.The contact gap,single coil height,coil width,and slot length of contact plate are chosen as optimized parameters,and the axial magnetic flux density at current peak,phase shift time,and conductor resistance are chosen as optimized targets.Regression equations of AMF characteristics and contact parameters,as well as the contact parameters,which have significant influences on AMF characteristics,are obtained.Multiple objective optimization of the axial magnetic flux density at current peak,the phase shift time,and the conductor resistance is performed to achieve optimal values of the contact parameters.It is coneluded that AMF characteristics become optimal when the contact gap is 20 mm,the single coil height is 15 mm,the coil width is 20 mm,and the slot length of contact plate is 30 mm.After optimization,the axial magnetic flux density at current peak increases to 0.565 T,the phase shift time decreases to 0.729 ms,and the conductor resistance decreases to 19.885 μΩ关键词
