Abstract

The invention discloses an alternating current and direct current railway signal switch machine mutual control reversing action circuit which comprises a first switch machine serving as a direct current switch machine and a second switch machine serving as a three-phase alternating current switch machine. The first switch machine comprises a switch machine direct current motor and a first switch machine self contact group which are in conductive connection; the second switch machine comprises a switch machine alternating current motor and a second switch machine self contact group which are in conductive connection; the switch machine direct-current motor is conductively connected with the direct-current power supply; the switch machine alternating-current motor is conductively connected with an alternating-current power supply. The direct-current power supply is conductively connected with the first switch machine self contact group through a second control switch; the alternating current power supply is conductively connected with the second switch machine self contact group through the first control switch; and the first switch machine self contact group is conductively connected with the second switch machine self contact group. According to the invention, on-off control is carried out on the contact groups of the alternating current switch machine and the direct current switch machine, so that the running-in test and service life test requirements of the switch machine can be met.

Description

technical field [0001] The invention relates to the technical field of circuit control, in particular to an AC / DC railway signal switch machine mutual control reversing action circuit. Background technique [0002] The switch machine refers to the important signal infrastructure equipment used to reliably change the position of the turnout, change the opening direction of the turnout, lock the tip rail of the turnout, and reflect the position of the turnout. It can well ensure driving safety, improve transportation efficiency, and improve the safety of driving personnel labor intensity. [0003] For the switch machine, in order to ensure its reliability, running-in test and life test are required. The run-in test (run-in test) and life test of the existing point machine are all controlled by a special control system for reciprocating action, and the control system mostly uses mechanical relays or electrical components. Therefore, after the control system is used for a long ...
