Abstract

PURPOSE:To miniaturize a device by turning off a GTO thyristor of a one-way power type arm when a semiconductor breaker is in a closing state and the current for a breaker is in the reverse direction. CONSTITUTION:A main circuit of a bilateral power type breaker is formed by such a way that a bilateral power type arm 3 connects the forward and reverse direction GTO thyristors 7-8 in parallel and connects a current balance reactor 5 in series, and it is formed by such a way that a one-way power type arm 4 connects a forward direction GTO thyristor 9 and a current balance reactor 6 in series. And, when the reverse load current is supplied to the breaker, an off-pulse is provided to a gate of the GTO thyristor 9 of the one- way power type arm 4 to be turned off. According to the constitution, the reflex current flowing between arms is prevented at the time of damping of the reverse load current.
