Rectifiers

The rectifier is a key component of the 660 VDC distribution system within rectifier stations for electric public transport systems. Its primary function is to convert alternating current (AC) into direct current (DC) traction voltage, which is then distributed across cable sections and the contact network.

Switch blocks

The DC switch block (positive field) plays a critical role in the 660 VDC distribution system within rectifier stations. These blocks are connected to the rectifier's positive pole through dedicated busbars. Their main function is to ensure the safe and reliable switching of traction voltage and to protect the corresponding cable and contact network sections used in electric public transport systems. Thanks to its modular design, the system can be easily expanded by adding additional blocks, allowing for the supply of extra contact line sections when necessary.

DC return cables

DC return cable field is a key element of the 660 VDC distribution system in rectifier stations. Its main purpose is to manage the return cables from the distribution network of public transport systems. These return cables are connected to tram rails, and the return field is connected to the rectifier’s negative terminal via busbars, thus completing the electrical circuit for various sections of the 660 VDC distribution network.
