National Science Museum Maglev
The National Science Museum Maglev () was a maglev line in Daejeon, South Korea that opened on 21 April 2008 and closed on 31 December 2020. It was a long line that connected the National Science Museum to the Expo Science Park in Yuseong District. It was the first maglev train line to begin commercial operation in the country. History The National Science Museum carried out installation work on infrastructure such as bridge piers, tracks, and stations from 2005 to May 2007. In June 2007, Hyundai Rotem and the Korea Institute of Machinery and Materials completed the comprehensive test run after installing UTM-02. On April 21, 2008, the line was opened, running 16 round trips daily on the track between the National Science Museum and Expo Science Park. As part of the 2014 Expo Science Park re-creation project, half of the section was demolished, leading to a sharp drop in visitors, and operations were completely suspended in 2020 due to the COVID-19 pandemic.

UTM-02
UTM-02 is a South Korean maglev train developed for the continuous research of magnetic levitation trains. The vehicle development was undertaken by the Korea Institute of Machinery and Materials. It was used on the National Science Museum Maglev line. History In 1989, South Korea began developing a maglev train at the Korea Institute of Machinery and Materials as a national research and development project. Hyundai Rotem, a company participating in the development project, succeeded in developing a 30 km/h vehicle for the Expo '93 exhibition in Daejeon. Afterwards, 43.5 billion won was invested in research and development to develop the pre-commercialization prototype UTM-01 in 1998 and UTM-02 in 2006. By developing UTM-02, the country secured the core technology for maglev trains. UTM-02 were managed by Hyundai Rotem until 2011, but after the contract expired, the National Science Museum took over management of the vehicles. Technology It was manufactured by Hyundai Rot ...

Maglev
Maglev (derived from '' magnetic levitation'') is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance. Compared to conventional railways, maglev trains have higher top speeds, superior acceleration and deceleration, lower maintenance costs, improved gradient handling, and lower noise. However, they are more expensive to build, cannot use existing infrastructure, and use more energy at high speeds. Maglev trains have set several speed records. The train speed record of was set by the experimental Japanese L0 Series maglev in 2015. From 2002 until 2021, the record for the highest operational speed of a passenger train of was held by the Shanghai maglev train, which uses German Transrapid technology. The service connects Shanghai Pudong International Airport and the outskirts of central Pudong, Shanghai. At its historical top speed, it covered the distance of in just over 8minutes. ...

Direct Current
Direct current (DC) is one-directional electric current, flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor (material), conductor such as a wire, but can also flow through semiconductors, electrical insulation, insulators, or even through a vacuum as in electron beam, electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A archaism, term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''Electric current, current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains Electronics, electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
