Abstract
PURPOSE:To keep a section switch in a closing-locked state, even if an accident is generated within a timer count time after the section switch is closed, by turning a lock contact OFF with the manual closing or forcible closing of the section switch. CONSTITUTION:Unlike conventional circuits, to the second ordinary opening contact 14 of a starting relay 10, the normally opening contact 42 of a switching auxiliary relay 33 is connected in parallel with each other. When a section switch 1 is manually closed or forcibly closed, then the switch auxiliary-relay 33 is conductively excited, and a first-a third normally opening contacts 39, 41, 42 are turned ON, and by turning the second normally opening contact 41 ON, a closing auxiliary relay 24 is conductively excited, and a normally opening contact 30 is turned ON, and a closing coil 28 and a retaining coil 29 are turned conductive, and along with the closing of the section switch, by turning the third normally opening contact 42 ON, a conduction circuit to an opening lock relay 13 is kept in a closing state. In the meantime, till the normally opening time limit contact 40 of a timer relay 38 is turned ON after the section switch is closed, a lock contact 12 is kept in an OFF-state, and when an accident is generated, then a closing-locked state is set.
