Converter is designed for traction system of 8t engineering vehicle which is used for tunnel construction, mining operations. The engineering vehicle has explosion-proof function, which can be used in coal mine and other explosive situations.
Functions of traction converter are as followings: It supplies VVVF power to traction motor, ensures that traction converter provides enough traction and baking in the case of full loaded, ensures that traction converter is shut down and restore the function of fault in the case of general faults, ensures that traction converter is shut down and automatic records fault in the case of serious faults.
