MAGLEV TRAIN

-

 



The front corners have magnets with north poles facing out, and the back corners have magnets with south poles outward. Electrifying the propulsion loops generates magnetic fields that both pull the train forward from the front and push it forward from behind. This floating magnet design creates a smooth trip.

A maglev system comprises five major components, namely levitation, guidance, input power transfer, propulsion and control systems, as shown in Fig. 3. Levitation force provides the upward lift to the vehicle, whereas propulsion force is responsible for propelling the vehicle forward

In a maglev system, the train is not only held up by magnets but also pulled forward by these magnets. Air friction will gradually slow the train down if the changing electromagnets aren't timed to pull it forward.

The engine for maglev trains is rather inconspicuous. Instead of using fossil fuels, the magnetic field created by the electrified coils in the guideway walls and the track combine to propel the train.

            The train was clocked at 603 kilometers per hour or 375 miles per hour. This is much faster than the Maglev trains already operating in Shanghai, China, and in South Korea, which run at speeds of 268 to 311 miles per hour and 68 miles per hour, respectively.

Each vehicle of the maglev train has eight batteries including four 440 V and four 24 V. Except for emergency-lighting depending on 24 V batteries, almost all train-borne systems including levitation and direction, braking, air-conditioning, and other ones are supplied by four 440 V batteries

Alternating Current

  What Is Alternating Current? An  alternating current  can be defined as a current that changes its magnitude and polarity at regular intervals of time. It can also be defined as an electrical current that repeatedly changes or reverses its direction opposite to that of Direct Current or DC, which always flows in a single direction as shown below From the graph, we can see that the charged particles in AC tend to start moving from zero. It increases to a maximum and then decreases back to zero completing one positive cycle. The particles then reverse their direction and reach the maximum in the opposite direction after which AC again returns to the original value completing a negative cycle. The same cycle is repeated again and again. Alternating currents are also accompanied usually by alternating voltages. Besides, alternating current is also easily transformed from a higher voltage level to a lower voltage level.

SOLAR TRANSFORMERS

  The transformers required for wind power and solar DPV require special design features to meet the challenging operating conditions. The industry today has developed different types of transformers for the application. The last few decades have seen very rapid development of renewable energy, especially, distributed photovoltaic (DPV) and wind power. It is estimated that at least 40 per cent of electricity generation by year 2040 would be from renewable energy sources and this would give appreciable reduction of the present level of carbon dioxide emissions of about 10 billion tons per year. The transformer industry is rising to this challenge and has developed special transformers for the DPV generation and wind generation. Transformers are critical components in solar energy production and distribution. Historically, transformers have ‘stepped-up’ or ‘stepped-down’ energy from non-renewable sources. There are different types of solar transformers including distribution, station, su
