The traction system of rail car is the "heart" part of track muffler company. It includes pantograph, main circuit breaker, line filter reactor, traction converter, traction motor, braking resistance, coupling and gear box of traction mechanical transmission system. Traction and traction motor are the core of the whole traction chain. Traction control technology is to realize the power distribution and speed regulation of train traction impedance muffler, which involves semiconductor converter technology and motor drive control technology. Traction control technology is an important core technology of railway vehicles, which provides punctuality for trains and ensures safe and reliable operation. Technical parameters of traction converter: nominal voltage: DC1500V; normal input voltage range: dc1000vdc1900v; output line voltage: ac1400v; output current of each phase: 570ka; braking frequency: 135hz.
