Abstract

A new type of switchgear, electro magnetic force driving actuator (EMFA) is developed and analyzed to be applicable to high voltage gas circuit breaker (HGCB). The transient analysis is performed to obtain the dynamic characteristics of the EMFA. The distribution of static magnetic flux is obtained by using the finite element method (FEM), and the governing equations, electric and kinematical equations, are solved by the time difference method (TDM). Fabrication and experiments were performed to prove the applicability of HGCB for overall class. By comparing experiment with simulated data, it is confirmed that analysis of dynamic characteristics of EMFA is appropriate to design
