Abstract
This invention discloses a dual-DC railway signal switch machine mutual control commutation circuit, including a first switch machine and a second switch machine as DC switch machines. The first switch machine includes a first switch machine DC motor and a first switch machine self-contact group electrically connected to each other. The second switch machine includes a second switch machine DC motor and a second switch machine self-contact group electrically connected to each other. The first and second switch machine DC motors are electrically connected to an external DC power supply. The external DC power supply is electrically connected to the first and second switch machine self-contact groups through the control switch. The first and second switch machine self-contact groups are electrically connected to each other through wires. This invention, by controlling the on / off state of the self-contact groups of the two DC switch machines, combined with the switch machine action logic control function of the self-contact groups, can meet the requirements of switch machine running-in tests and life tests.
