Abstract
PURPOSE: To interlock automatically street-car lines by interlocking the up-line with the down-one in an electrically interlocking apparatus when a street-car exists between specific sections or street-car voltage is dropped to a specified voltage or less.
CONSTITUTION: A street-car up-line 13 and down-line 14 respectively connected to feeder substations 11, 12 when applied to a DC feeder system are interconnected by a bilateral breaker 17 constituted from semiconductors. Also, at the rails 15, 16 sides of the up- and down-lines are provided street-car position detectors 18, 19 which detect the presence of street-car in the related section to generate output, and further between the up-line 13 and rail 15 and between the down-line 14 and rail 16 are provided respectively voltage relays 20, 21 to generate output when the voltage drop of each-street car line exceeds the specified value. And a breaker 17 is operated by the action of either the detector 18 or 19, or of the relay 20 or 21 to shunt the current of street-car to the street-car lines 13, 14.
