He focussed on solving the difficulties of high power, electrically powered mainline railway system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Electrification System
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units ( passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings and contacted by a pantograph, or a third rail mounted at track level and contacted by a sliding " pickup ...

Max Huber (statesman)
Hans Max Huber (28 December 1874, in Zürich – 1 January 1960, in Zürich) was a Swiss lawyer and diplomat who represented Switzerland at a series of international conferences and institutions. His life Max Huber was born in Zurich in 1874 as the son of Peter Emil Huber-Werdmüller, engineer and founder of Maschinenfabrik Oerlikon, and Anna Marie, née Werdmüller (* June 22, 1844; † October 5, 1911). His younger brother was Emil Huber-Stockar. Max Huber studied law at the universities of University of Lausanne, Lausanne, University of Zurich, Zurich and Humboldt University of Berlin, Berlin from 1894 to 1897, graduating with a doctorate in Berlin in 1897. He then worked for two years as secretary to the board of the Swiss Trade and Industry Association. After several extensive trips to America, Australia, and India, he was appointed Professor of Constitutional Law, Canon Law and Public International Law at University of Zurich from 1902 to 1914 and retained this title until ...

15 KV AC Railway Electrification
Railway electrification using at are used on transport railways in Rail transport in Germany, Germany, Rail transport in Austria, Austria, Rail transport in Switzerland, Switzerland, Rail transport in Sweden, Sweden, and Rail transport in Norway, Norway. The high voltage enables high power transmission with the lower frequency reducing the losses of the traction motors that were available at the beginning of the 20th century. Globally, railway electrification in late 20th century tends to use 25 kV AC railway electrification, AC systems which has become the preferred standard for new railway electrifications. Nevertheless, local extensions of the existing network is commonplace. In particular, the Gotthard Base Tunnel (opened on 1 June 2016) uses 15 kV, 16.7 Hz electrification. Due to high conversion costs, it is unlikely that existing systems will be converted to despite the fact that this would reduce the weight of the on-board step-down transformers to one t ...

Utility Frequency
The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user. In large parts of the world this is 50 Hz, although in the Americas and parts of Asia it is typically 60 Hz. Current usage by country or region is given in the list of mains electricity by country. During the development of commercial electric power systems in the late-19th and early-20th centuries, many different frequencies (and voltages) had been used. Large investment in equipment at one frequency made standardization a slow process. However, as of the turn of the 21st century, places that now use the 50 Hz frequency tend to use 220–240 V, and those that now use 60 Hz tend to use 100–127 V. Both frequencies coexist today (Japan uses both) with no great technical reason to prefer one ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternating Current
Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, Fan (machine), fans and electric lamps into a wall socket. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', respectively, as when they modify ''Electric current, current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa (the full period is called a ''wave cycle, cycle''). "Alternating current" most commonly refers to power distribution, but a wide range of other appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seebach-Wettingen Railway Electrification Trial
The Seebach-Wettingen railway electrification trial (1905-1909) was an important milestone in the development of Railway electrification system, electric railways. Maschinenfabrik Oerlikon (MFO) demonstrated the suitability of single-phase alternating current at high voltage for long-distance railway operation with the Seebach-Wettingen single-phase alternating current test facility. For this purpose, MFO electrified the 19.45-kilometre-long Swiss Federal Railways (SBB) Wettingen–Effretikon railway, route from Seebach to Wettingen at its own expense with single-phase alternating current at 15,000 volts. Overview By 1900, the use of direct current (DC), usually at 500-600 volts, to supply power to electric trams and trains was well-established. Examples include Trams in Budapest (from 1887) and the Liverpool Overhead Railway (opened 1893). This was satisfactory for urban systems but, for long distance railways, a higher voltage was desirable to reduce energy losses. The 106&n ...

The Urban agglomeration, urban area was home to 1.45 million people (2020), while the Zurich Metropolitan Area, Zurich metropolitan area had a total population of 2.1 million (2020). Zurich is a hub for railways, roads, and air traffic. Both Zurich Airport and Zürich Hauptbahnhof, Zurich's main railway station are the largest and busiest in the country. Permanently settled for over 2,000 years, Zurich was founded by the Roman Empire, Romans, who called it '. However, early settlements have been found dating back more than 6,400 years (although this only indicates human presence in the area and not the presence of a town that early). During the Middle Ages, Zurich gained the independent and privileged status of imperial immediacy and, in 1519 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
