Abstract
With the development of converter technology and computer control technology, AC speed regulation system has attracted world attention. AC drive systems shows tremendous advantages in the performance indicators, the device volume, equipment maintenance, energy saving and even the environmental protection. Both the main drive system and the auxiliary drive system of HXD3 type electric locomotive adopts AC drive technology and computer control technology, the entire electrical system design adhere to the high starting point, the leading principle, and fully consider the actual needs of the high power freight electric locomotive. What is more, it use advanced, mature, reliable technology and undertake all-around design according to the demand of standardization, series, modular, information.According to the rapid development of China’s railway, the railway locomotives’research is more and more extensive and deep. This paper mainly introduces the HXD3 type electric locomotive and the AC-DC-AC transmission system in railway locomotive operation and maintenance of the situation.The first chapter is the introduction, introduces the configuration of the AC drive system, the advantages of AC drive technology, the characteristics of the HXD3 electric locomotive and the electric drive system.
Keywords: HXD3 electric locomotive , AC-DC-AC drive , four-quadrant rectifier , electric circuit
