Abstract

PURPOSE: To enable the sure protection of the electric rolling stock by one time commutation fail detection against the repetition of ON-OFF state of the acceleration switch opposing to the will of the driver by a method wherein the detected state of commutation fail is holded for a prescribed time even if the acceleration switch, etc., is made to be OFF state.
CONSTITUTION: When a chopper 3 fails to commutate, a commutation fail detecting circuit 9 operates to make a thyristor 19 to be ON state. By this operation, a thyristor 18 is made to be OFF state to make a contactor 4 or 5 to open cutting off a motor 2 from the power source 1. The whole voltage of the power source 1 is applied to the motor 2 during the delay time to make the contactor 4 or 5 to be open, and the rolling stock receives a radical accelerating shock. Consequently the driver's body moves opposing to the will of himself, and as a result even if the acceleration switch 11 repeats the ON-OFF state, the thyristor 19 is kept in OFF state and the thyristor 18 does not made to be ON state again in the next time. By this way, the electric rolling stock can be made to stop surely by the one time commutation fail detection.
