The BBÖ 1180.001 was an electric locomotive of the Austrian Federal Railways BBÖ, which was returned to the manufacturer without ever having run. The locomotive was designed as a so-called converter locomotive , in which the single-phase alternating current from the catenary on the locomotive was converted into a three-phase alternating current to supply the traction motors with the help of a rotating converter .

history

In 1923, Ganz & Co. in Budapest , under the direction of Kandó, built a test locomotive that had a high-voltage phase converter instead of a transformer. The converter was as synchronous - rotary converters designed with oil-cooled stator winding. The machine has been successfully tested under 15 kV / 50 Hz. Disadvantages were the complicated structure of the mechanical part and that the locomotive could only be operated at a small number of synchronous continuous speeds. The difference in performance compared to the Austrian locomotives, however, was considerable: it had an output of 2,000 kW, while the BBÖ 1080 , which was only 5 t lighter and had the same axle formula, developed an output of only 1,020 kW. The BBÖ therefore wanted to investigate whether similar results could also be achieved below 15 kV / 16⅔ Hz and ordered an express train locomotive, the BBÖ 1470.001 and a freight train locomotive, the 1180.001.

construction

The mechanical part was manufactured by the Floridsdorf locomotive factory , which contrary to customary practice also acted as the main supplier. The reason was probably that the supplier of the electrical part, Ganz & Co., was based in Budapest, i.e. abroad.

testing

The 1180.001 and 1470.001 were delivered in 1925 and stationed in Bludenz . The problems during the test drives with the 1470.001 meant that the 1180.001 had to serve as a spare part dispenser for the 1470.001. The two machines were returned to the suppliers in the same year without the 1180.001 ever running independently. The vehicles remained in Bludenz for over ten years. Only then was the Floridsdorf locomotive factory able to agree on replacement services with Ganz & Co.

technology

The contact line voltage was connected directly to the primary winding of the oil-cooled synchronous single-armature converter via the pantograph, which supplied the two asynchronous traction motors with 2-, 3- or 4-phase three-phase current. The motors were pole-changing and could be operated with 12, 8 or 6 poles. The speeds of the continuous drive levels were 16 km / h, 25 km / h, 33 km / h, 50 km / h and 67 km / h. The two traction motors were in the locomotive body and drove the drive axles on the already from the BBÖ 1280 known Kandó-pinion drive on.
