The WAG-9 is an electric locomotive of Indian Railways for operation with 25 kV AC with a frequency of 50 Hz, which is built on in 1997. After the first six locomotives had been imported from Switzerland , the construction of the locomotives began in the Chittaranjan Locomotive Works (CLW) and was later extended to other Indian locomotive factories. The designation of the series consists of W for wide ' Breitspur ', A for alternating current 'Alternating current' and G for goods 'Güter' for freight locomotives . A 9 follows the hyphen to identify the 9th generation of WAG locomotives.
history
From the late 1970s onwards, India developed successful tap changer locomotive series such as the WAG-5 , WAG-7 , WAP-4 and WCAM-3 . Nevertheless, the technology of these series was out of date at the beginning of the 1990s, because in Europe the first large series of high-performance locomotives with three-phase drive and microprocessor control were built, which were more efficient and had a powerful regenerative brake .
In July 1993, the ABB -Landesgesellschaft der Schweiz received an order for the delivery of locomotives with three-phase drives in GTO thyristor technology, with 22 freight locomotives WAG-9 and 11 passenger locomotives WAP-5 to be delivered. A technology transfer contract was also linked to the supply contract, which enabled further production of the locomotives in India.
The locomotive body and bogies of the first six locomotives with the numbers 30000 to 31005 were built in the ABB plant in Dandenong in Australia and provided with the electrical equipment in Switzerland in the ABB traction equipment assembly plant TRAMONT in Zurich Oerlikon . The fully assembled and commissioned locomotives were loaded on a platform wagon and taken over the Hauenstein Pass to Basel for shipping in the Rhine port . From there the locomotives were brought to Rotterdam and loaded with a floating crane as project cargo onto a ship of the Shipping Corporation of India (SCI), which was heading for the port of Calcutta , where the six locomotives arrived in early 1997.
Another 14 locomotives were assembled in the CLW from material deliveries from Switzerland and Australia. They were numbered 31006 to 31021. After that, CLW began manufacturing its own locomotives using components that were procured from Indian sub-suppliers, including the ABB plant in Vadodara . The first locomotive made entirely in India was the 31022, which bears the name नवयुग Navyug , German for 'New Age' .
technology
On the current collector and, arranged on the roof vacuum - the main switch , the energy is supplied to the disposed under the locomotive body transformer supplied. The energy is fed to the two oil-cooled converters via four secondary windings with a nominal voltage of 1270 V, which supply the six drive bearings in the bogies with energy. The motors are designed as three-phase asynchronous machines with squirrel cage rotors .
The drive train of the locomotive is similar to that of the SBB Re 460 , but like the first version of the Eurotunnel class 9, instead of the converter with three voltage levels in the intermediate circuit , it uses one with only two voltage levels. For the first time, a filter winding was added to the transformer , which is located between the traction windings.
variants
To distinguish the sub-series letters H for Heavy , heavy ' and i for IGBT used. The two H in the abbreviation HH stand for high 'higher' and indicate a higher axle load and the higher performance of the sub-series WAG-9HH.
The following variants of the WAG-9 are built:
- WAG-9: Original version
- WAG-9H: Version with additional ballast, total weight: 132 t
- WAG-9i: Version with converter in IGBT technology
- WAG-9Hi: Version with additional ballast and converter in IGBT technology
- WAG-9HH: 9000 HP variant
painting
With a few exceptions, all locomotives are painted green with a yellow stripe in the middle.
The exceptions are:
- WAG-9H 31022 Navshakti , which had two white stripes instead of the yellow stripe
- WAG-9H 31086 Dr Silver , purple-red with white decorative stripes and wall-high lettering G \ 9
