Electric hydraulic excavator control system
The invention discloses an electric hydraulic excavator control system, and belongs to the technical field of the control of an electric machine. The electric hydraulic excavator control system comprises a front end transformer (1), a junction box, a current collector ring, a high-voltage electric control cabinet, a high-voltage electromotor (12), a coupler and a hydraulic pump, wherein the electric power is sequentially supplied by a distribution network to the high-voltage electromotor (12) sequentially through the front end transformer (1), the junction box, the current collector ring and the high-voltage electric control cabinet by virtue of a high-voltage cable, and the high-voltage electromotor (12) is connected with the hydraulic pump in a transmission manner through the coupler. The electric power of a power grid is accessed to a hydraulic excavator, and the hydraulic pump is driven by utilizing the high-voltage electromotor so as to supply power to the machine; the application cost of the machine can be greatly saved, and zero pollution and zero emission can be realized.
