A pure electric alternating current transmission system comprises a vehicle control unit which is respectively connected with a quick charging system, a power battery, a battery thermal management system, a high-voltage power distribution system, a low-voltage power supply system and a frequency conversion control system through a data communication bus and a sensor. The vehicle control unit monitors the states of the power battery, the battery heat management system, the high-voltage power distribution system, the low-voltage power supply system and the variable-frequency control system, and sends control commands to the high-voltage power distribution system and the variable-frequency control system according to the states of the systems and operation commands of a driver; the frequency conversion control system controls and drives a left wheel traction motor, a right wheel traction motor, a hydraulic oil pump motor, a cooling fan of the telex system and the cabin air conditioning system to work. The telex system supplies power to the cabin air conditioning system. By means of the electric drive mining dump truck, pure electric operation of the electric drive mining dump truck can be achieved, reduction of mine fuel consumption is facilitated, the mine production cost is reduced, and meanwhile green development of mines is achieved.
