Abstract
The utility model relates to a circuit of a main transmission system of a hinge type dumper. The circuit comprises a main generator and a driving motor, and the motor is controlled by the main generator sequentially through a rectification unit and an inversion unit; a chopping unit and a brake resistor are arranged between the rectification unit and the driving motor, and the chopping unit and the brake resistor are connected in series to form a high-speed brake unit. When the hinge type dumper conducts high-speed braking, a pulsant direct current is converted into a direct current stable in voltage through the chopping unit, electric energy is then converted by the current into heat energy through the brake resistor, and therefore energy during high-speed braking of the hinge type dumper is released; braking force needing to be applied to a brake system is reduced, and the machining difficulty of the brake system is accordingly and effectively relieved.
