Abstract

Electrical equipment EE arranged in the roof of an electrically driven railway vehicle, said vehicle being equipped with at least one pantograph (2) and a roof line L conveying the current, received from an catenary line (1), from the connection to said pantograph (2) to the electrical driving devices (4) of the vehicle, said electrical equipment EE comprising a circuit-breaking device (3) for protecting said electrical driving devices and being arranged on a mechanical support (40), characterised in that said electrical equipment EE comprises a measuring device DM comprising at least means (33) for measuring the amperage of the current transmitted from the catenary (1) to the roof line L, which means are arranged on said mechanical support (40), and in that said electrical equipment EE comprises a computer (D) which controls the actuation of said circuit-breaking device (3).

Claims

1. Electrical equipment EE arranged on the roof of an electrically driven railway vehicle, said vehicle being equipped with at least one pantograph (2) and with a roof line L conveying the current, received from an catenary line (1), from the connection to said pantograph (2) to the electrical driving devices (4) of the vehicle, said electrical equipment EE comprising a circuit-breaking device (3) for protecting said electrical driving devices and being arranged on a mechanical support (40), characterised in that said electrical equipment EE comprises a measuring device DM comprising at least means (33) for measuring the amperage of the current transmitted from the catenary (1) to the roof line L, which means are arranged on said mechanical support (40), and in that said electrical equipment EE comprises a computer (D) which controls the actuation of said circuit-breaking device (3).

2. Electrical equipment EE according to claim 1, characterised in that the measuring device DM comprises means (34) for measuring the voltage on the mechanical support (40).

3. Electrical equipment EE according to claim 1, taken separately or in combination, characterised in that said voltage measuring means (34) and amperage measuring means (33) are mounted within a single insulator (25).

4. Electrical equipment EE according to claim 3, characterised in that the measuring device DM comprises a high-voltage environment confined within the first recess (28) provided in the insulator (25) and a low-voltage environment confined in a second recess (29) of said insulator (25).

5. Electrical equipment EE according to claim 1, characterised in that at least one of the following pieces of protective equipment is arranged on the mechanical support (40):

an isolating switch (36) for earthing (37),

an overvoltage protective device (38),

an AC circuit breaker (3).

6. Electrical equipment EE according to claim 1, characterised in that it comprises the electrical connections between the equipment arranged on the support (40).

7. Electrical equipment EE according to claim 1, characterised in that the measuring device DM is connected, on the one hand, directly to the pantograph (2) by a single connection (52) and, on the other hand, to the circuit breaker (3) by a single connection (51).

8. Electrical equipment EE according to claim 1, characterised in that the measuring device DM measures the current at the hot spot.
