The invention discloses a direct current traction power supply system and a protective method, and utilizes direct current protective device outlet information and a short circuit fault mark value as a criterion to judge various direct current short circuit faults. When the short fault occurs, an alternating current incoming line breaker closest to a fault element is subjected to brake separating; if the sum of the fault mark values of the element, measured and computed after the brake separating, is more than or equal to 1, permanent fault is determined, the alternating current incoming line breakers of other traction substations in the whole line are subjected to brake separating, and related direct current isolation switches are subjected to brake separating to enable the alternating current incoming line breakers of the traction substation in the whole line to be subjected to switching on, so the power supply of the system can be restored; and if the sum of the fault mark values of ...

The invention discloses a thyristor rectification tractive power supply system and a protective method. When a short-circuit fault occurs, the thyristor of a traction substation thyristor rectifier closest to a fault element is stopped from working; if the sum value of the fault mark values, measured and calculated after the thyristor is stopped from working, of the element is larger than or equal to 1, a permanent fault is determined, the thyristors of other traction substation thyristor rectifiers of a whole line are stopped from working, all related direct-current isolation switches are opened, the thyristors of the traction substation thyristor rectifiers of the whole line return to work, the power supply of the system is restored, and if the sum value is not larger than or equal to 1, a temporary fault is determined, the related thyristors return to work, and the normal power supply of the system is restored. According to the thyristor rectification tractive power supply system and ...
