The rectifier of the V-TPED series are intended to convert AC to DC in traction substations of electrified railways, as well as urban electrified transport.
The following functions are implemented in the rectifier:
- control of breakdown of diodes;
- the output of a signal for the disconnection of power switches of both direct current and input AC breakers in case of rectifier malfunctions;
- cooling system of rectifier diodes is made with the use of coolers on “heat pipes” with forced cooling by fans with a smooth change in the speed of rotation of the blades, depending on the operating mode and temperature in the power cabinet;
- on the rectifier doors are installed electromagnetic blocking lock and auxiliary monitoring block-contacts.
