Abstract

The invention discloses a power system of an electric-driven dumper, the electric-driven dumper and a power switching method of the electric-driven dumper. The power system comprises an external drive system, a detecting element and a control device, wherein the external drive system comprises a bow collector; the detecting element detects the traveling state of the electric-driven dumper and transmits a traveling state signal to the control device; the control device determines the power mode required by the electric-driven dumper according to the traveling state signal. Under an external power mode, the control device controls the bow collector to contact with an alternating-current wiring system to introduce alternating currents obtained from the alternating-current wiring system to serve as the power source of the external drive system, large power can be provided for the electric-driven dumper and especially the heavy-loaded electric-driven dumper climbing up a slope, and accordingly the speed of the electric-driven dumper can be increased, and production efficiency can be further increased.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an electric drive dump truck power system, an electric drive dump truck and a method. Background technique [0002] At present, due to its good maneuverability, fast turnover speed, and strong climbing ability, electric drive mining dump trucks are widely used in open-pit mining, transportation and other fields and become the main vehicle. The basic structure of the electric transmission mining dump truck is an integral frame, a dual-axle rear drive, and a rear unloading type. It is driven by AC variable frequency traction technology. This technology uses a high-power diesel engine to drive a generator to generate electricity, converting mechanical energy into electrical energy. After rectification, excitation and inverter control, the current is supplied to the traction motor in the driving wheel or on the side of the wheel, which converts electrical energy into mechanical e...
