China Railways DJ1
The China Railways DJ1 is a high power mainline electric freight locomotive built as a double locomotive unit of two nominally independent single cab units. History and design The locomotives are based on a technology transfer agreement between Siemens and Zhuzou Electric locomotive works (ZELW). The first three locomotives were built by Siemens in Austria, and the remaining 17 were built in China. The electrical components in the locomotive are based upon Siemens' EuroSprinter design (second generation using water-cooled GTO inverters). The traction motors are asynchronous AC type, and are nose suspended on the axle, regenerative electric braking is possible with a braking force of approximately , and an electric braking power of , overall efficiency of the machine is more than 85%. 3 of the units were manufactured by Siemens in Austria, the remaining 17 in China; the first locomotive was produced in 2001. The first china manufactured unit was produced in 2002. Production of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
25 KV AC Locomotives
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the for ...

Electric Locomotives Of China
Electricity is the set of physics, physical Phenomenon, phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing Work (physics), work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an externa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Daqin Railway
Daqin (; alternative transliterations include Tachin, Tai-Ch'in) is the ancient Chinese name for the Roman Empire or, depending on context, the Near East, especially Syria. It literally means "great Qin"; Qin () being the name of the founding dynasty of the Chinese Empire. Historian John Foster defined it as "the Roman Empire, or rather that part of it which alone was known to the Chinese, Syria". Its basic facets such as laws, customs, dress, and currency were explained in Chinese sources. Its medieval incarnation was described in histories during the Tang dynasty (618–907 AD) onwards as ''Fulin'' (), which Friedrich Hirth and other scholars have identified as the Byzantine Empire. Daqin was also commonly associated with the Syriac-speaking Nestorian Christians who lived in China during the Tang dynasty. Chinese sources describe several ancient Roman embassies arriving in China, beginning in 166 AD and lasting into the 3rd century. These early embassies were said to arrive ...

Qinhuangdao
Qinhuangdao (; ) is a port city on the coast of China in northern Hebei. It is administratively a prefecture-level city, about east of Beijing, on the Bohai Sea, the innermost gulf of the Yellow Sea. Its population during the 2020 national census was 3,136,879, with 1,881,047 people living in the built-up (or 'metro') area made up of 4 urban districts. History The city's name "''Qinhuangdao''" literally means " Qin Emperor island", and is allegedly originated from the legend that the Jieshishan Scenic Area in Changli County was the site of First Emperor of Qin's famous ritual during his fourth and final survey tour to the east (东巡) in 210 BC. The "island" refers to the Nanshan area of the Port of Qinhuangdao at the southern edge of the city's Haigang District, which used to be a small offshore island until the late Qing dynasty, when dumping of dredged silt joined it to the mainland after the Guangxu Emperor approved the port's construction in the late 19th century.

Locotrol
Locotrol is a product of GE Transportation that permits railway locomotives to be distributed throughout the length of a train (distributed power). It is installed on more than 17,000 locomotives around the world, sending signals from the lead locomotive and via radio to the remote control locomotives. History Locotrol was developed in the 1960s by an Ohio telephone and electronics manufacturer, North Electric Company. The technology was later purchased by GE-Harris Railway Electronics predecessor Harris Controls Systems Division of Harris Corporation. The electronics were mounted in a separate railcar, but have since been miniaturised into relatively small cabinets with much of the functionality contained in software. Early Locotrol customers included the Southern Railway, Norfolk & Western Railway, Detroit Edison, Canadian Pacific and Australia's Mount Newman Mining and Queensland Rail. Today numerous railroads use Locotrol, with systems deployed globally numbering in the thousand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IGBT
An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch, which, as it was developed, came to combine high efficiency and fast switching. It consists of four alternating layers (P–N–P–N) that are controlled by a metal–oxide–semiconductor (MOS) gate structure. Although the structure of the IGBT is topologically the same as 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), electric cars, trains, variable-speed refrigerators, lamp ballasts, arc-welding machines, induction hobs, and air conditioners. Since it is designed to turn on and off rapidly, the IGBT can synthesize complex waveforms with pulse-width modulation and low-pass filters, so it is also used in switching a ...
