TRACTION DRIVES

FOR TRAM VAGONS AND TROLLEYS KPTT SERIES

 

          Traction drives KPTT series are intended for tram motion operation.

          Traction drives KPTT series contain in their structure all complete electric equipments which realize motion, except traction motors.

         Traction drives are applied either in new tram wagons or during wagons modernization (during complete overhaul realization).

         Traction drives KPTT series have modifications for tram wagons with two or with four motor trolleys.

          Traction drives KPTT series make voltage and traction motors excite current impulse regulation during following tram’s work modes:

·   tram motion with different velocities in diapason from 5 to 70 km/h;

·   short time tram motion in “runaway” mode (that is at output voltage absence);

·   recuperative braking at connected to the contact network users presence and switching to rheostat substitute braking during its absence.

Traction drive work is providing at 1200m altitude, cooling air temperature values from -40°C to +40°C and air relative humidity 98% at temperature +25°C.

Traction drives main component parts technical parameters are given in Table 1.

Complete traction drives provide accumulated in accelerative masses energy recuperation to the power supply during braking that essentially reduces electric energy expenses on the motion.
