Zusammenfassung: | The invention discloses a turnout control circuit for an AC switch machine. The turnout control circuit is characterized by comprising a starting circuit, an actuating circuit and an indication circuit, wherein the starting circuit comprises a first turnout starting relay 1DQJ, a second turnout starting relay 2DQJ and a first turnout starting relay repeating relay 1DQJF; when the turnout control circuit is used for the occasion that a turnout positioning control relay DCJ or a reverse position control relay FCJ is sucked up. The first turnout starting relay 1DQJ is subjected to excitation suction, and the second turnout starting relay 2DQJ achieves pole switching; the actuating circuit is used for delivering a 380 V AC power source to the outdoor turnout AC switch machine according to theexcitation suction conditions of the first turnout starting relay 1DQJ, the first turnout starting relay repeating relay 1DQJF and the second turnout starting relay 2DQJ in the starting circuit to enable the 380 V AC power so |
