Abstract: A disconnector for overvoltage protector (OVP) is equipment which intercepts a circuit safely, when OVP breaks down in short circuit mode. As a disconnector, a Circuit Breaker (CB) is normally used. When a large current such as a lightning surge flows, switchgear of CB comes floating according to the electromagnetic force generated by large current which flows into a switchgear. The function of OVP is spoiled by this influence. If the problem which the switchgear comes floating can be solved, even when a large lightning surge flows through it, electrical aparatus can be protected by OVP.We have been analyzing this switchgear floating mechanisms using finit element method. This paper presents a way of preventing switchgear floating.
