Abstract
PURPOSE: To prevent a commutation failure of a thyrister by detecting the opening of single feeder section among the multiple series of feeder sections with a command device and changing over the pattern with a pattern change-over device to reduce the regeneration brake force of an electric car.
CONSTITUTION: A car runs in feeder section 10b and 10c divided in multiple number. When a transformer 6c fails, a breaker 8c opens and a monitor 13 sends out an open condition signal to a transmitter 14 which sends out a change-over signal via a transmitting line 12 to a pattern change-over device 22 via an antenna 17, an amplifier 18 and discriminator 19. When the pattern change-over device receives the change-over signal, it opens the first pattern generator 20 and connects the second pattern generator 21 and a rectifier 23 giving the second pattern command to the rectifier 23 whereby the motor is driven with reduced regeneration brake current.
