Title: Controlled separation of return
network powered from two sides
The problem the inventor(s) wanted to solve Limiting stray currents during operation as
well as balanced distribution of tensions between rails and the earth
(surrounding environment).
Description. To limit stray currents track sections containing rails founded on track
ballast are separated from track sections
constructed in the ballast-free technology. In order to avoid the
adverse phenomena of electroerosion of the connector and wheel rims as well
as emission of electromagnetic interferences, the isolation connectors ought
to be closed for the time of the train's ride.
Advantages Limiting stray currents as well as electroerosion of the connector
and wheel rims.
Stage of development. Design of electric circuits .
