Abstract

The invention discloses a mutual control reversing action circuit of a double-direct-current railway signal switch machine. The circuit comprises a first switch machine and a second switch machine which serve as direct-current switch machines. The first switch machine comprises a first switch machine direct current motor and a first switch machine self contact group which are in conductive connection; the second switch machine comprises a second switch machine direct current motor and a second switch machine self contact group which are in conductive connection; the first point switch direct-current motor and the second point switch direct-current motor are respectively and conductively connected with an external direct-current power supply; the external direct-current power supply is conductively connected with the first switch machine self contact group and the second switch machine self contact group through the control switch; and the first switch machine self contact group is conductively connected with the second switch machine self contact group through a wire. On-off control is carried out on the contact groups of the two direct-current switch machines, the switch machine action logic control function of the contact groups of the switch machines is combined, and the running-in test and service life test requirements of the switch machines can be met.

Description

technical field [0001] The invention relates to the technical field of circuit control, in particular to a dual-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...
