Description

On tram lines where open ways are laid and there is no possibility of arrival of the car (for example: the high-speed tram on Borshchagovka, the forest route between Shevchenko Square and Pushchey-Voditsey in Kiev) for performance of maintenance functions on contact network energized of GKP "Kiyevelektrotrans" has on hand the special tram KSV-2 car (fig. 1). It is equipped with lifting rotating device with site and perfectly adapted for repair installation works, however has essential shortcoming: impossibility of operation on new construction and emergency and recovery, repair works when there is no tension in contact network. For performance of such works the KSV-2 car tower needed to be equipped with autonomous power source which would allow to carry out the movement of the car and performance of the functions by it.

Jointly with service of power providing KP "Kiyevpastrans" the converter of direct current (the pulse-width converter on IGBT modules, further the THORN) is developed for the traction electric drive of the KSV-2 tram which is intended for transformation of the straightened tension arriving from the diesel generator to constant voltage with restriction of amplitude of output current 190A and mean of input current 90A. Thus, the converter limits consumption of power at the level of 50 kW. The THORN is loading the direct current motor with consecutive excitation. In fig. 2 appearance the THORN without casing is shown.
