The locomotives of the series ЭП1 (EP1) of the Russian Railways (RŽD) are wide-gauge (1520 mm) electric locomotives . They were created as a derivative for passenger train service from the RŽD series ВЛ65 and will be delivered to the Novocherkassk electric locomotive factory from 1999 onwards. With the modifications ЭП1 M (EP1 M ) and ЭП1 П (EP1 P ) , 863 locomotives were built by May 2016. They were nicknamed Bricks, Rasender Bricks, or KAMAZ by the factory service .

Characteristics of the electric locomotive

With an output of 4700 kW, the locomotives are capable of moving a train with a mass of 1440 t at a gradient of 9 ‰ at 80 km / h. The special feature of the locomotive compared to the RŽD series ВЛ65 is the suspension of the traction motors, which in the warenП1 were carried out in the support-frame suspension . This allowed smoother running at higher speeds. The wheel arrangement is identical to that of the RŽD series ВЛ65, Bo 'Bo' Bo '. The ЭП1 locomotive can thus be described as an electric locomotive of the ВЛ65 series , modernized for passenger train service. A work with multiple controls as it was possible with the ВЛ65 is not intended for the locomotive.

Delivery of the new electric locomotive

The electric locomotives of the series ЭП1 were positioned by the manufacturer as a replacement for the Soviet electric locomotives ВЛ60 П, K and the previously imported electric locomotives of the series ČS4 and ČS4T from Czechoslovakia . The main differences between the locomotives and the ВЛ65 are as follows:

  • Use of new traction drive motors НБ-520 (NB-520) in the support frame suspension instead of the outdated НБ-514 (NB-514) with a pawl bearing drive .
  • Installation of a frequency-phase number converter ПЧФ (PTSchF), which led to the use of auxiliary machines to supply 40 V 16 2/3 Hz at low speeds and loads.
  • Introduction of a micro- processor system administration and diagnostics МСУД (MSUD).

The ЭП1 series electric locomotive is the first electric locomotive with a microprocessor produced by the Novocherkassk electric locomotive factory . The microprocessor management system controls the main devices and some relays, manages the rectifier-inverter conversion and feeds the traction motors. This led to the management of the electric locomotive in four regimes;

  1. Autoregulation: This is a semi-automatic regime in which the machine operator uses the control to give up the maximum current required and thus the acceleration. With the help of the handles of the setpoint device, he sets the required speed. The electric locomotive accelerates up to the entered speed and automatically supports you on level sections and on slopes or inclines.
  2. Manual regulation: This is used by the control in the event of an accident. This is like a conventional control of electric locomotives with a handwheel and control unit. The angle of rotation of the handwheel determines the opening angle of the thyristors . The position of the handle of the setpoint generator has no bearing on the speed.
  3. Car responsibility: This control is structured in a similar way to the control according to the line control system. In this system, the electric locomotive and the train are managed by the microprocessor. This has data such as the profile of the route, permitted speeds, arrangement of signals, arrangement of stations, plan of train occupancy, temporary speed restrictions, etc. In this regime, travel and braking data, application of the electropneumatic and pneumatic brakes of the train are collected, the train is therefore managed automatically. The machinist presses a button on the driver's cab to start the regime, after which he only performs control functions. If the operator turns the control handwheel or actuates the driver's brake valve, the system automatically switches to the advisory mode , accompanied by visual and audio support.
  4. Adviser: This is a regime of the administration, which uses the functions of the regime auto-regulation and partly the auto-responsibility. Here the machinist manages the locomotive according to the auto-regulation regime . Recommendations from the microprocessor about the actual actions of the machinist in the present moment and the current situation appear on a display. The microprocessor does not directly manage the locomotive, it only gives advice.

The motor fans of the locomotives can always work in two speed ranges, on the one hand in the range of high speeds, where they are driven with 380 V, 50 Hz, and on the other hand in the range of low speeds, here they are operated with voltage 40–90 V, 16 2/3 Hz driven. The drive motors of the motor compressor always work in the range of high speeds .

Modernizations

From 2006 on, the modernized electric locomotives ЭП1 M (EP1 M ) and ЭП1 П (EP1 P ) were produced. In the latter, the traction force was increased with the change in the axle drive. It was specially designed for operation on a demanding route profile and for use in climatic conditions with a humidity of the outside air of 95 to 100%. The numbering was continued with the ЭП1 M , the ЭП1 П received separate numbering, starting with the 001 .

The modernized locomotives differed from the ЭП1 by their main shape, especially by the asymmetrical arrangement of the pantographs and the engineer's cab made of plastic with the changed workplace of the machinist. From now on, the management of the locomotive was a one-man operation . At least that gave a completely different face to the locomotives. In practice, this form of operation has not always been adopted; there are known operations of trains without auxiliary machinists in the Svir - Murmansk section , preferably with the 15/16 Moscow - Murmansk and 21/22 St. Petersburg - Murmansk trains .

business

The following companies received the locomotives for operation: West Siberian Railway (Depot karasuk ), Far Eastern Railway (Depot Khabarovsk ), October Railway (Depot Kandalaksha ), Krasnoyarsk Railway (depots Krasnoyarsk and Abakan ) Privolzhskaya Railway (Depot Saratov ) , East Siberian Railway (depot Irkutsk ), Trans-Baikal Railway (depot Belogorsk ), North Caucasus Railway (depot kavkazskaya ), Yugo-Vostochnaya schelesnaja doroga (depot Rossosh ), South Urals Railway (depot Kartaly ) and Gorkovskaya zheleznaja doroga ( Krasnoufimsk Depot ). The largest number of electric locomotives were in the Krasnoyarsk Depot, the Saratov Depot and the Belogorsk Depot. In the depots, the locomotives completely replaced the ČS4 and ČS4T locomotives . The ČS4 were taken out of service and the ČS4T passed on to the Balaschow and Rossosch depots of the Yugo-Vostochnaja schelesnaja doroga and the Kawkasskaja depot of the Severo-Kawkasskaja schelesnaja doroga. On the October Railway, the Krasnoyarskaya zhelesnaja doroga, the Vostochno-Sibirskaya zelesnaja doroga and other railways, the new electric locomotives completely replaced the old locomotives SŽD series ВЛ60 , RŽD series ВЛ65 and SŽD series ВЛ80 .
