Abstract

PURPOSE:To prevent excess current from being generated at the time of an electric rolling stock passing a non-voltage zone due to the error operation, and an equipment from being damaged along with the generation of the excess current, by stopping the output control of a power converting means automatically when an electric vehicle is moved into the non-voltage zone, and by re-starting the output control after passing the non-voltage zone. CONSTITUTION:When an electric rolling stock is moved into a non-voltage zone, then a stringing 1 is set to be of non-voltage, but the output of gate signal is generated, and current is to be fed to a transformer 3 from a voltage converting means 4, and voltage is detected by an AC voltage detector 13. By a non-voltage detecting means 5, a difference between the voltage detected by the detector 13, and feed voltage from the stringing 1 is detected, and a timer is worked. When non-voltage is continuously kept for a specified time, then by a section (non-voltage zone) passing detecting means 6, the input of signal to a control means 7 is provided. By the control means 7, the gate signal of a GTO thyristor 41 is turned OFF, and the output control of the power converting means 4 is automatically stopped, and when the electric rolling stock is passes through the non-voltage zone and is moved into a feed zone, then the gate signal is turned ON, and the output control is re-started.
