Overhead Catenary
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, Electric multiple unit, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is ''overhead line''. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. An overhead line consists of one or more wires (or Overhead conductor rail, rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a High voltage, high-voltage Electricity distribution, electrical grid. Overview Electric trains that collect their current from overhead lines use a de ...

VVVF
A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor, AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the input electricity. Depending on its Topology (electrical circuits), topology, it controls the associated voltage or electric current, current variation., quote is per definition on p. 4 of NEMA Standards Publication ICS 7.2-2021. VFDs are used in applications ranging from small appliances to large compressors. Systems using VFDs can be more efficient than hydraulics, hydraulic systems, such as in systems with pumps and damper control for fans. Since the 1980s, power electronics technology has reduced VFD cost and size and has improved performance through advances in semiconductor switching devices, drive topologies, simulation and control techniques ...

IGBT
An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily forming an electronic switch. It was developed to combine high efficiency with fast switching. It consists of four alternating layers (NPNP) that are controlled by a metal–oxide–semiconductor (MOS) gate structure. Although the structure of the IGBT is topologically similar to a thyristor with a " MOS" gate ( MOS-gate thyristor), the thyristor action is completely suppressed, and only the transistor action is permitted in the entire device operation range. It is used in switching power supplies in high-power applications: variable-frequency drives (VFDs) for motor control in electric cars, trains, variable-speed refrigerators, and air conditioners, as well as lamp ballasts, arc-welding machines, photovoltaic and hybrid inverters, uninterruptible power supply systems (UPS), and induction stoves. Since it is designed to turn on and off rapidly, the IGBT can synthesize complex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Takasaki Line
The Takasaki Line () is a Japanese railway line which connects Ōmiya Station in Saitama, Saitama Prefecture and Takasaki Station in Takasaki, Gunma Prefecture. It is owned and operated by the East Japan Railway Company (JR East). All services on the line (excluding through Shonan-Shinjuku Line trains) run to/from Ueno Station in Tokyo via the Tōhoku Main Line. The line was extended to Tokyo Station via the Ueno-Tokyo Line that opened in March 2015. As the Takasaki Line serves many major cities within Saitama Prefecture, it is a vital means of transport within the prefecture. National Route 17 and its historical predecessor, the Nakasendō, run parallel to the line. Services Services on the Takasaki Line are typically divided into three categories: services to or from Ueno, Shōnan-Shinjuku Line services, and Ueno-Tokyo Line services. Between Ueno and Ōmiya, trains share the track with the Tōhoku Main Line ( Utsunomiya Line), both of which serve as ''de facto'' expre ...
