Abstract

PURPOSE:To positively operate an opening light priority circuit, by effectively preventing short-circuit in case of simultaneous operation by performing polarity inversion by using a transistor circuit. CONSTITUTION:When a closing operation command and an opening operation command are simultaneously entered from the control station 2 side, a transistor Q1 is turned ON by closing operation (Cs, ON), and overcurrent intends to flow to the transistor Q1 when performing opening operation (Ts, ON) at that time. However, since base current flows to another transistor Q2 through a contact Ts-a resistance R2 at the same time and the transistor Q2 is turned ON, potential between resistance R1 and a diode D1 drops to N, the base current of the transistor Q1 is instantaneously interrupted and the transistor Q1 is turned OFF. Thus, the transistor Q1 reaches an opening condition, the potential of a link line L rises through the contact Ts-a diode D2, a relay Tx for opening of the station 2 side to be controlled is operated and a breaker is opened.
