Abstract

PURPOSE: To enable a trolley bus to travel by a low-pressure battery power source at the time of emergency traveling by providing a change-over switch which changes-over the DC input side of the inverter and a connection change- over means which changes-over the connection of the induction electric motor.
CONSTITUTION: At the time of normal traveling, DC power is led in from a DC stringing 1 through a trolley pole 2 and the DC power is supplied to a variable voltage . variable frequency inverter 6 through a filter circuit consisting of a filter reactor 3 and a filter capacitor 4 and a change-over switch 5. In the case of emergency traveling, with a change-over of the change-over switch 5 to the side of a battery power source 12, an induction electric motor 7A is changed-over from a Y connection to a Δ connection. Hereby, the emergency necessary tractive force characteristics can be satisfied.
