DIRECT CURRENT FEEDING DEVICE
Document Type and Number:
Japanese Patent JPS6218338
Kind Code:
A
Abstract:
PURPOSE:To cut off current in trouble instantly by configurating a device in such a way that two sets of diode bridge circuits are combined with a set of breakers, both power running and regenerative current are allowed to flow through the above said breakers, and a diode series circuit is provided. CONSTITUTION:In two sets of diode bridge circuits 21 ad 41 which are connected in series, cathode sides of diodes 22a and 22c, and diodes 42a and 42c are connected with one another to form a power running bus bar 23. And thyristor breaker 24 is provided between the said bus bar 23 and a common connecting line 25 on anode sides of diodes 22b and 22d, and diodes 42b and 42d. In addition, a diode series circuit 30 is connected with the said circuit 21 and 41 in parallel, then a node 31 between diodes 28 and 29 is connected with a regenerative bus bar 32 with which a bi-directional power transducer 33 is connected. Each of following nodes such as one 26 between the diodes 22a and 22b, one 27 between the diodes 22c and 22d, one 46 between the diodes 42a and 42b and one 47 between the diodes 42c and 42d, is connected with each of electric car lines 9a, 9b, 10a, and 10b by way of each of direct current disconnecting switches 8a through 8d respectively.
