Propulsion converter for locomotives KONTRAC GP1000AC Thyristor propulsion converter which converts AC network electric power fed from a transformer output into propulsion power for DC traction motors. The converter is used in the process of modernization of old diode locomotives into thyristorized locomotives as well as for building new locomotives. Replacement of diode converters with thyristor converters and implementation of vehicle control unit for traction application (VCU) ensures conversion of old diode locomotives to modern thyristor locomotives with superior traction and exploitation characteristics: 1) Continuous speed and torque control of traction motors (both at traction and braking mode) which optimizes adhesion, saves energy, decreases wear of vital parts and provides electronic overload, sliding and torsion vibrations protection. 2) Sequential control of thyristor bridges limits consumption of reactive power. Features - Easy maintenance - Machine room mounting - Robust and powerful semiconductors - Air cooled cooling system - Electrically and mechanically compatible with the existing diode locomotive power supply equipment Basic technical data If you have any questions about our products, please do not hesitate to contact us!

Pretvarač glavnog pogona KONTRAC GP1000AC Tiristorski pretvarač koji pretvara energiju na izlazu sekundara transformatora u energiju potrebnu za pokretanje istosmjernih motora lokomotive. Pretvarač se koristi prilikom modernizacije starih diodnih lokomotiva u tiristorizirane, jednako kao i prilikom izrade novih lokomotiva. Zamjena diodnih pretvarača s tiristorskim pretvaračima, uz ugradnju nadređenog računala vozila omogućava preobrazbu starih lokomotiva u moderne lokomotive sa sljedećim naprednim tehničkim karakteristikama: 1) Kontinuirano upravljanje brzinom i momentom vučnih motora (u režimu vuče kao i u režimu kočenja) optimira adheziju, štedi energiju, smanjuje trošenje vitalnih pogonskih dijelova 2) Sekvencijalno upravljanje tiristorskim mostovima ograničava potrošnju jalove energije. Osnovne karakteristike pretvarača - Jednostavno održavanje - Smještaj u strojarnici - Robusni i snažni poluvodiči - Hlađenje zrakom - Električki i mehanički kompatibilni s postojećim diodnim pretvaračima
