<p>The invention relates to an actuating system for controlling and adjusting the speed of the electric engines with six driving axles. According to the invention, the actuating system consists of some pantographs (1.1 and 1.2) for gathering voltage from a suspension wire (2), some separators (3.1 and 3.2), a transformer (4), a disjunctor (5) for connecting/disconnecting the supply voltage, a surge arrester (6) for protection against overvoltages, a device (7) for grounding the high voltage circuit, a measurement and protection circuit (8), having a main transformer (9), equipped with a temperature transducer (9.16), for supplying some hauling/braking circuits, for heating the train and auxiliary services, some semi-controlled rectifiers (18.1, 19.1, 18.2, 19.2, 18.3 and 19.3), by means of which there is continuously regulated the supply voltage of the six hauling engines (33.1, 33.2, 33.3, 33.4, 33.5 and 33.6), depending on the information relating to the absorbed current, the voltage on each engine and the speed of each axle, obtained by some current transducers (32.1.1, 32.1.2, 32.2.1, 32.2.2, 32.3.1 and 32.3.2), voltage transducers (35.1.1, 35.1.2, 35.2.1, 35.2.2, 35.3.1 and 35.3.2) and speed tranducers (36.1.1, 36.1.2, 36.2.1, 36.2.2, 36.3.1 and 36.3.2), as well as some electropneumatic contactors which allow the insulation of any hauling engine (33.1, 33.2, 33.3, 33.4, 33.5 and 33.6). The system also comprises some electronic blocks, by means of which there are provided two ways of running the engine; automatical and manual, as well as a block for detecting the skidding and blocking the driving axles of the engine.</p> |
