Electrical equipment arranged in the roof of an electrically driven railway vehicle
First Claim
1. Electrical equipment arranged on a roof of an electrically driven railway vehicle, said vehicle being equipped with at least one pantograph and with a roof line conveying a supply current, received from a catenary line, from a connection to said pantograph to electrical driving devices of the vehicle,wherein said electrical equipment comprises, arranged on a mechanical support fixed on the roof of the vehicle:
- a circuit-breaking device for protecting said electrical driving devices;
a measuring device comprising at least means for measuring the amperage and means for measuring the voltage of the supply current transmitted from the catenary line to the roof line, said voltage measuring means and amperage measuring means being mounted within a single insulator; and
a computer which controls the actuation of said circuit-breaking device based on a first signal representing the value of the amperage of the supply current of the catenary line delivered by the means for measuring the amperage and a second signal representing the voltage present on the catenary line delivered by the means for measuring the voltage, andwherein said measuring device is connected, on the one hand, directly to the pantograph by a first single connection and, on the other hand, to the circuit breaker by a second single connection.
