Abstract

PURPOSE: To operate a dynamic brake even when trolley wires are broken and to reduce the load of a pneumatic brake by providing an electropneumatic operator having a trolley wire voltage detector and predetermined functions.
CONSTITUTION: With a brake notch command 10 sent when trolley wire are broken and electric motor vehicle are stopped, a chopper control phase shift pattern corresponding to speed and a brake current is outputted to the output points A, B of an electropneumatic operator 19. In this case, a predetermined chopper control phase shift pattern is sent to a chopper control unit 13 through the output relay contact 18-b of a trolley wire voltage detector 17 to perform dynamic brake control. The difference between the brake pattern and the dynamic brake pattern shorts as brake force due to the above process and a pneumatic brake pattern corresponding to the shorted value is sent to a pneumatic brake unit 13 from the output point C of the electropneumatic operator 19.
