Problems solved by technology

[0007] In practice, things are more complicated because the measuring instruments are in a high voltage grid environment (from 750 volts to direct current to 25,000 volts alternating current), while it is in a low-voltage environment when it comes to signal generation and processing

Embodiment Construction

[0038] A disconnect switch 36 for ground 37 and an overvoltage protection device 38 .

[0039] The grounding disconnect switch 36 is adapted to be manually, electrically or pneumatically switched between a first state called a "working" state and a second state, in which the disconnect switch 36 is not electrically connected to any device, and in the second state Two-state, disconnect switch 36 connects both upstream and downstream of circuit breaker 3 to ground circuit 37 . The overvoltage protection device 38 can automatically switch between the first state and the second state. The protection device 38 operates like a closed circuit breaker in the first state, and when the voltage between its two terminals exceeds a predetermined In the second state, the protective device 38 operates like an open circuit breaker.

[0040] figure 2 Denotes measuring device DM between points A and B of roof line L.

[0041] like figure 2 As shown, on the roof line L, and in a completely...

Abstract

The invention relates to an electric equipment (EE) arranged on the roof of an electric traction railway vehicle, said vehicle being equipped with at least one pantograph (2) and a roof line conveying the current received from a catenary line (1) from the connection to said pantograph (2) towards traction electric devices (4) of the vehicle, said electric equipment (EE) including a circuit breaker apparatus (3) for protecting said traction electric devices and being provided on a mechanical holder (40), characterised in that said electric equipment (EE) includes a measuring device (DM) including at least intensity measuring means (33) of the current transmitted from the catenary (1) to the roof line (L) that are provided on said mechanical holder (40), and in that said electric equipment (EE) includes a calculator (D) that controls the activation of said circuit breaker apparatus (3).

Description

technical field [0001] The present invention relates to electrical equipment located on top of an electric traction railway vehicle, said railway vehicle being equipped with at least one pantograph and a roof conductor which connects the current intercepted from the suspension cables with said pantograph The joint of the frame is sent to the electric traction device of the railway vehicle, said electric device includes at least one instrument for protecting said electric traction device, and the instrument is located on a mechanical support. Background technique [0002] Rail cars include a lot of equipment on top. Thus, single-phase, respectively direct-current pantographs can be seen, which serve to convey current from the suspension cables, which are supplied with corresponding single-phase direct current, to the roof lines that supply the vehicle with electrical energy. Also visible are some high voltage electrical equipment such as a single phase / DC converter, a ground...
