Title:
DIRECT CURRENT FEEDING DEVICE
Document Type and Number:
Japanese Patent JPS626838
Kind Code:
A
Abstract:
PURPOSE:To surely deal with the accident by combining interrupting devices with a diode bridge circuit to which a diode series circuit is connected in parallel with same polarity, and applying power running current and regenerative current against three electric car lines through a pair of the interrupting devices. CONSTITUTION:The cathode sides of diodes 22a, 22c in a diode bridge circuit 21 is connected to a bus bar for power running. A thyrister interrupting device 23 is connected between a common connecting point 24 to the cathodes of diodes 22a, 22c and a common connecting point 25 to the anodes of diodes 22b, 22d. And, the common connecting point 26, 27 between the diodes 22a, 22b while between the diodes 22c, 22d are respectively connected to the first and the second electric car lines 10a, 10b through direct current interrupting devices 9a, 9b. Further, this connecting point 25 is connected to the third electric car line through a direct current interrupting device 9c. The diode series circuit 29 is connected to above bridge circuit 21 in parallel and the common connecting point 30 to the diodes 28a, 28b is connected to a bus bar for regenerating.
