Technical Data, Description:

The reconstruction involved the replacement of old technology for new one and construction modifications of the building where the converter station is located. The building owner required to move the technology to the basement of the building, which was smaller than the minimum space for storing the technology. It was necessary to build a new loading pit for the transport of all technology, remake the basement of the building for the installation of transformers cell and switchboards, and at the same time to change the standardized dimension of the switchboards to atypical.

Almost the whole converter station technology was replaced during the reconstruction. In addition to traction transformers (3x 2.5 MVA), the entire DC and AC part was reconstructed, ie a 22 kV switchboard (8 arrays), a rectifier (three 6-pulse), a traction block (20 feeders and 2 longitudinal conjunction) and dispatching control technology controlled from energy-technology dispatching.

The switchover of the old to the new technology was carried out in parts to maintain the continuous operation of the converter station (two units fully available connected via busbars to all traction sections).

The construction was competed in association with Metrostav a.s. a Elektrizace železnic a.s. as the leader of the association.
