The SŽD series ВЛ80 ( transcribed WL80 ) is a double locomotive designed for 25 kV 50 Hz alternating current of the SŽD and its successor company RŽD for freight traffic . The abbreviation BЛ (WL) stands for the initials of Vladimir Ilyich Lenin .
The series was built for over thirty years in various stages of modification, which differ in a letter attached to the basic type. In total, over four thousand VL80 locomotives left the Novocherkassk electric locomotive factory . In the mechanical part, the locomotive corresponds to the DC locomotive of the SŽD series ВЛ10 .
Series and modification levels
- ВЛ80 (translit. WL80 ): The first series that was originally equipped with a mercury vapor rectifier and was later converted to a silicon bridge rectifier .
- ВЛ80 K (translit. WL80 K , Russian к ремниевые полупроводниковые выпрямители ) The modification stage, built from 1963 to 1971, is equipped with a silicon bridge rectifier and improved secondary suspension, of which 695 were built.
- ВЛ80 T (translit. WL80 T , Russian т ормоз for brake) From 1967 this was built with an electrical resistance brake , of which 1317 locomotives left the factory by 1984.
- ВЛ80 P (translit. WL80 R , Russian р екуперативное торможение ) In the design equipped with a recuperation brake , the rectifiers were replaced by DC converters . The stepless traction control and the recuperation brake made these units particularly suitable for use on the mountain routes in the Caucasus and in the east of Siberia . By 1986 373 units of this series had been built.
- ВЛ80 C (translit. WL80 S , Russian с истема многих единиц , abbreviated СМЕ) This series was built from 1979 to 1995 in 2746 units. It is the largest series in terms of numbers and has multiple controls .
- ВЛ80 CM (translit. WL80 SM ) was an attempt to modernize the ВЛ80 C after the collapse of the Soviet Union. Only four pieces were built, all of which are assigned to the Bataisk depot .
In addition to the series listed above, the following locomotives were developed, which were never sufficiently mature for series production:
- ВЛ80 а : variant with asynchronous motors
- ВЛ80 б : variant with brushless DC traction motors
- ВЛ80 вр : variant of the ВЛ80 б with recuperation brake
- ВЛ81 : Variant of the ВЛ80 with fully sprung traction motors and low-tension linkage of the bogies
- ВЛ84 : from the ВЛ81 further developed eight-axle double locomotive, which should replace the ВЛ80.
technology
The locomotive consists of two autonomous locomotive halves that are operated in multiple controls. The ВЛ80 C series also allows the operation of three and four sections. Some ВЛ80 P were delivered with three sections.
Each half of the locomotive is supported by two identical bogies with welded frames. The primary suspension is made with leaf and coil springs . The tensile force of the two TED NB-418K6 pivot bearing motors is transmitted via the pivot pins of the bogies. The drive motors are provided with gears at both shaft ends with a ratio of 1: 5.176.
The locomotive body of each half of the locomotive is equipped with a pantograph above the driver's cab and a main switch . The box contains the transformer , the two rectifiers and the EKG-8G step switch . The locomotives of the ВЛ80 P series have two VIP-2200 DC choppers instead of the last two units.
The auxiliaries are supplied with three-phase current via a phase splitter . The voltage of the auxiliary system winding can be regulated in three stages by a manually operated high-voltage switch on the transformer, so that the three-phase network is supplied with 380 V under nominal load in the range from 19 kV to 29 kV contact line voltage .
The control circuits are supplied with 50 V via a transformer with regulating winding, with a subsequent diode bridge and smoothing chokes .
The step switch EKG-8G has 30 contacts that can be de-energized and 4 load switches. The step switch is driven by a 50 V direct current motor with an output of 550 watts. Two switchover coils prevent overcurrents when switching on the stages.
Countries of operation
The railway companies of the successor states of the Soviet Union took over the locomotives from the SŽD. They have the following names:
- Russia : RŽD ВЛ80
- Belarus : BC УЛ80
- Ukraine : UZ ВЛ80
- Kazakhstan : KTZ ВЛ80
- Uzbekistan : UTY ВЛ80
Modifications
In Ukraine it is known that a large number of the locomotives were converted into single-section locomotives for passenger train service, as there was an overhang on the locomotives for freight train service around 2000. Starting in 2004, the locomotives were equipped with two driver's cabs, received the facilities for operating passenger transport and were designated as the ВЛ40 U series.
To date, more than 80 vehicles have been converted.
