Abstract

PURPOSE: To assure the safety of a workman in a trolley section, by providing an emergency stop switch in the trolley section and by operating an emergency stop brake when a trolley power source is disconnected by the switch.
CONSTITUTION: When an unattended vehicle is running in a trolley section and a workman repairing the trolley line of a running track 21 or the like presses an emergency stop switch 44 to prevent danger, a trip circuit 45 acts to open a circuit breaker 43 to disconnect a trolley power source 41. At that time, a phase disappearance detector 13 which serves also for power detection is turned on to constrict the phase of a main rectifier 6. As a result, an abnormality detection relay acts to stop the unattended vehicle by an emergency brake. After work is finished, a workman reset switch in the trolley section is operated to restore the original state. The safety of the workman in the trolley section is thus assured.
