Let's talk about electric locomotives

I noticed that on Yap is very much like the theme of the railroad and rolling stock. I understand that the main locomotives few people are surprised, why tell you about industrial electric EL 21.
There will be 17 photos and some text, please do not break the compilation, when finished, will inform

Electric EL21 - industrial electric DC, which was built in the GDR on Locomotive Works Hans Baimler it. Lokomotivbau Elektrotechnische Werke for the enterprises of the Soviet Union.



Structurally electric EL21 (EL21) is a development of electric EL1 (EL1), previously released with the same plant to the USSR. Compared with its predecessors new locomotives safer work in difficult climatic conditions.

Electric locomotives were built from 1981 to 1986.

EL21 operated at the moment in the way of industrial enterprises, quarries and so on. N.



Electric consists of two sections, each of which has a driver's cab. The body sections are based on the one hand to the extreme, and on the other - on the overall average Tandem axle. In the middle bogie wheel pair are not connected. Wheel pair have a diameter of 1220 mm. Electric locomotive is equipped with six traction motors (TED) GBM-350 / 1500XC with compensation winding. Hanging TED supporting-axial. Pulling helical gear with a ratio of 5, 58 Bushes jaw with roller bearings.



The locomotive is powered by the central (top) and lateral contact wire DC voltage of 1, 5 kV. Traction motors of each bogie can be connected in series and parallel. When dynamic braking is used self-excitation of the engine, thus TED pairs connected in parallel and each group TED closed on his band resistors. It can operate the locomotive at low speeds when TEDy all connected in series.

The locomotive has two compressor capacity CT-6 5 7 m3 / min at a shaft speed of 850 rev / min for air composition and supply contactors and electro-injectors of electric sand. The cooling of traction motors and starting resistors by using six fans.

TED hours Power: 350 kW
Speed ​​Time mode: 31 km / h
TED Continuous power: 290 kW
The speed of continuous operation: 33, 6 km / h

Weight of locomotive - 160 tonnes, the minimum radius of the curves passable at 5 km / h - 80 m.



that's all, I hope you liked it. And finally, a picture of an unknown artist, hanging in the smoking depot
