Tender Details

This market relates to the development and supply of 3 capacity filters for systems separation sections (SSP), located at interfaces between the electrified rail lines in 1500 V continuous and 25 kV - 50 Hz alternative.

The power circuitTrains uses the catenary to inject the current and the rails to ensure the return of the traction current (RCT). This transit causes rail-sol tensions (TRS), which, in certain configurations, require specific treatment to limit electrical risks and preserveInfrastructure.

In electrification 25 kV-50 Hz, the rail is put to the ground regularly to reduce the TRS, while in 1500 V continuous, it must imperatively be isolated to avoid electrolytic corrosion.

To SSP, a SAS of protective is put in place to prevent currentContinue to escape to the earth by the alternating tracks. This SAS is framed by insulating joints of continuity (JIC) and equipped with a filtering device allowing:

- to block the residual direct current,

- to let the alternating current transit normally to theSubject.

Historically, this function was ensured by a resonant shunt (LC series filter granted to 50 Hz). However, this device, installed in the 1970s, today has limits:

- Partial blockage of harmonic components,

- abnormal rail-sol voltage elevationsexceeding s ...
