FS Class E.464
The E.464 is a class of Italian railways electric locomotives. They were introduced in the course of the 1990s for hauling light trains, especially for commuter service. They were acquired by FS Trenitalia to replace the old E.424 and E.646, dating from the 1940s and 1950s. The class was originally designed by ABB Trazione, later ADTranz (now part of the Bombardier group), and produced in the Italian plant of Vado Ligure. Cost per unit is 2.6 million Euro. With 717 locomotives currently in service (as of December 2015) the E.464 is the largest class in use by Trenitalia, and also the most numerous Italian locomotive class ever in service. History The E.464 derives from a project launched by the Italian Ferrovie dello Stato in the 1980s for a "modular" class of locomotives which would be easily adapted to commuter, inter-regional and cargo services. Initially, types with 4-axle (Bo-Bo, E.453/E.454) and 6-axle (Bo-Bo-Bo, E.665/E.666) were devised, the latter for cargo service ...

Three-phase
Three-phase electric power (abbreviated 3φ) is a common type of alternating current used in electricity generation, Electric power transmission, transmission, and Electric power distribution, distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power. Three-phase electrical power was developed in the 1880s by multiple people. Three-phase power works by the voltage and currents being 120 degrees phase shift, out of phase on the three wires. As an AC system it allows the voltages to be easily stepped up using transformers to high voltage for transmission, and back down for distribution, giving high efficiency. A three-wire three-phase circuit is usually more economical than an equivalent two-wire Single-phase electric power, single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a giv ...

Inverter (electrical)
A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC. The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source. A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry. Static inverters do not use moving parts in the conversion process. Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and vol ...

3000 V DC Locomotives
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Paderno D'Adda
Paderno d'Adda ( Brianzöö: ; Bergamasque: ) is a town and ''comune'' in the province of Lecco, in Lombardy. It is well known in the rest of Italy for the cast-iron San Michele Bridge built in the late nineteenth century following the Tour Eiffel style. It is said that Leonardo da Vinci used the Paderno's scenery as base for his famous painting Virgin of the Rocks The ''Virgin of the Rocks'' ( it, Vergine delle rocce), sometimes the ''Madonna of the Rocks'', is the name of two paintings by the Italian Renaissance artist Leonardo da Vinci, of the same subject, with a composition which is identical except fo ....

Lombardy
Lombardy ( it, Lombardia, Lombard language, Lombard: ''Lombardia'' or ''Lumbardia' '') is an administrative regions of Italy, region of Italy that covers ; it is located in the northern-central part of the country and has a population of about 10 million people, constituting more than one-sixth of Italy's population. Over a fifth of the Italian gross domestic product (GDP) is produced in the region. The Lombardy region is located between the Alps mountain range and tributaries of the Po river, and includes Milan, the largest metropolitan area in the country, and among the largest in the European Union (EU). Of the fifty-eight UNESCO World Heritage Sites in Italy, eleven are in Lombardy. Virgil, Pliny the Elder, Ambrose, Gerolamo Cardano, Caravaggio, Claudio Monteverdi, Antonio Stradivari, Cesare Beccaria, Alessandro Volta and Alessandro Manzoni; and popes Pope John XXIII, John XXIII and Pope Paul VI, Paul VI originated in the area of modern-day Lombardy region.

Engine-generator
An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an ''engine–generator set'' or a ''gen-set''. In many contexts, the engine is taken for granted and the combined unit is simply called a ''generator''. An engine–generator may be a fixed installation, part of a vehicle, or made small enough to be portable. Components In addition to the engine and generator, engine–generators generally include a fuel supply, a constant engine speed regulator (governor) and a generator voltage regulator, cooling and exhaust systems, and lubrication system. Units larger than about 1 kW rating often have a battery and electric starter motor; very large units may start with compressed air either to an air driven starter motor or introduced directly to the engine cylinders to initiate engine rotation. Standby power generating units often include an automatic start ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gate Turn-off Thyristor
A gate turn-off thyristor (GTO) is a special type of thyristor, which is a high-power (.e.g. 1200V AC) semiconductor device. It was invented by General Electric. GTOs, as opposed to normal thyristors, are fully controllable switches which can be turned on and off by their gate lead. Device description Normal thyristors (silicon-controlled rectifiers) are not fully controllable switches (a "fully controllable switch" can be turned on and off at will). Thyristors can only be turned on using the gate lead, but cannot be turned off using the gate lead. Thyristors are switched on by a gate signal, but even after the gate signal is de-asserted (removed, reverse biased), the thyristor remains in the on state until a turn-off condition occurs (which can be the application of a reverse voltage to the terminals or a decrease of the forward current below a certain threshold value known as the "holding current"). Thus, a thyristor behaves like a normal semiconductor diode after it is turned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scharfenberg Coupler
The Scharfenberg coupler (german: Scharfenbergkupplung, abbreviated ''Schaku'') is a commonly used type of fully automatic railway coupling. Designed in 1903 by Karl Scharfenberg in Königsberg, Germany (today Kaliningrad, Russia), the coupler has gradually spread from transit trains to regular passenger service trains, although outside Europe its use is generally restricted to mass transit systems. The ''Schaku'' is superior in many ways to the AAR (Janney/knuckle) coupler because it also automates electrical and pneumatic connections and disconnections. However, there is no standard for the placement of these electro-pneumatic connections. Some rail operators have placed them on the sides while others have placed them either below or above the mechanical portion of the coupler. . Working principles The face of the Scharfenberg coupler has a protruding cone and a matching cup. Inside the cone there is a rigid metal hoop connected to a revolving, spring-loaded metal disk with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
