Non-contact power supply rail transit system and demonstration application
Non-contact power supply is one of the hot research topics at home and abroad, it has the incomparable advantage over traditional methods in power transmission in many areas of industrial production and daily life. At present,, non-contact power supply has been shown to be a more secure and convenient way of power supply in many areas of industrial production and daily life (flammable and explosive occasions, biological, medical, consumer electronics and transportation, etc.), compared with the traditional way of power transmission, and it is known as "the 22nd century top ten scientific and technological inventions. This technology is expected to lead the development of related technology.
Over the past 20 years, China's urbanization process has achieved remarkable results. In the process of urbanization, the problems caused by the development should be paid highly attention, especially the urban traffic, urban energy, urban environmental problems and etc. As a kind of efficient, convenient, energy saving, economy, safety, environmental friendly, the transportation mode of big capacity, rail transportation is an important measure to improve the transport efficiency, the quality of cities and towns, and the development of regional economy.
We need to research a non-contact transmission of traction power supply rail transit system based on the electromagnetic field near field resonance coupling principle to achieve high power, security and stability of power. By this technology, we can solve problems like power transmission losses, mechanical wear and corresponding erection and maintenance which caused by the current traction power supply system of the pantograph and catenary which depends on the conductor directly physical contact. In order to ensure safe, reliable and efficient operation of the rail transit system and satisfy the great demand for the development scale of urban rail transit in our country, this technology is necessary.
Non-contact traction power supply technology development will be an innovation in rail transit technology field; it can effectively support the development of the intelligent urban rail transit in our country, the realization of the non-contact traction power supply system scientific theory basis, and also for the safety and efficient operation of non-contact traction power supply system. It has great significance in providing key technical support, at the same time, the study also will enact related industries and national standards, develop key technology application demonstration, and lead innovative smart urban rail transit development.
