基于正交试验设计的40.5kV真空断路器电磁斥力机构储能电容优化设计研究
Optimal Design of Storage Capacitor of Electromagnetic Repulsion Mechanism in 40.5 kV Vacuum Circuit Breaker Based on Orthogonal Test Design
摘要
Abstract
The electromagnetic repulsion mechanism can improve the opening speed of the 40.5 kV vacuum circuit breaker,thus improve the stability of whole power system.In this study,three main factors,i.e.,number of coil turns,storage capacitance and charging voltage,were selected to comprehensively determine the minimum energy of storage capacitor of electromagnetic repulsion mechanism for the 40.5 kV vacuum circuit breaker.Based on the principle of orthogonal test design,three levels were set for each factor and nine tests were conducted.Then,numerical simulation tests were conducted via finite element modeling.Finally,regression analysis on the test data and optimization were performed.The results show that among the three factors,charging voltage has the most significant influence on the motion performance,storage capacitance ranks second,and number of coil turns ranks third.The regression equation of moving velocity of repulsion disk with the three factors is /v=-10.583+0.071N+0.018U+0.169C.Eventually,it is concluded that the energy of storage capacitor gets the minimum 3.6 kJ when charging voltage is 600 V,storage capacitance is 20 mF and number of coil turns is 20.关键词
