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+0.169 C. Eventually

it is concluded that the energy of storage capacitor gets the minimum 3.6 k J when charging voltage is 600 V

storage capacitance is 20 m F and number of coil turns is 20.
