Electrification is the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source. The broad meaning of the term, such as in the history of technology, economic history, and economic development, usually applies to a region or national economy. Broadly speaking, electrification was the build-out of the electricity generation and electric power distribution systems that occurred in Britain, the United States, and other now-developed countries from the mid-1880s until around 1950 and is still in progress in rural areas in some developing countries. This included the transition in manufacturing from line shaft and belt drive using steam engines and water power to electric motors.
Electrified railway traction power supply system
The invention relates to an electrified railway traction power supply system which is low in investment, is smooth for obtaining a current and is convenient to maintain. Rail webs outside two steel rails of a rail are respectively provided with one insulating strip; then a power supply strip is respectively arranged outside each insulating strip; each vibration inductive switch is connected in series with a sound inductive switch and a light-operated inductive switch; one ends of the connected switches are connected to the power supply strips at one sides; the other ends of the connected switches are connected with feed lines; the power supply strips at the other sides are connected with return wires. Power receiving frames at a headstock side and a tailstock side of a train are in contact with the power supply strips; when the train passes through a zone, the vibration inductive switches are closed, the sound inductive switches are closed, the light-operated inductive switches are closed, the power supply strips in the zone supply power, the power receiving frames of the train obtain a current and the train runs; when the train runs into a next power supply zone, the next power supply section is powered on, and power supply is stopped in the power supply zone. The aims of low investment, smoothness for obtaining the current and convenience for maintenance are fulfilled.
