Run testing of trolleybus with a modernized traction drive control system.
Preliminary trial tests of ZiU-682 trolleybus with a modernized traction drive control system have been completed in Ordzhonikidzevskoye trolleybus depo in the city of Ekaterinburg.
The new control system functioning on IGBT-transistors, developed and produced by “ASC” CJSC, brings a previous trolleybus model in terms of its technical features to a most advanced and up-to-date level. New implementation provides for smooth acceleration and braking along with almost a twofold energy saving, multiple reliability growth and maintenance efforts reduction. The equipment package for modernization can be installed on other types of DC- driven trolleybuses and trams as well.
The original technical solutions, applied by “ASC” specialists, made it possible to reduce the modernization package price significantly as compared with equipment of other producers without detriment to technical features. The multi-authority commission for acceptance of equipment into serial production is scheduled for November, 2016.
