An electric drive fracturing device and a braking method therefor are provided. The electric drive fracturing device includes an electric drive fracturing device body and a braking system. The electric drive fracturing device body includes a plunger pump and a control system. The braking system includes a brake trigger component and a brake execution component. The brake trigger component transmits a brake signal to the control system, and after receiving the brake signal transmitted by the brake trigger component, the control system controls the brake execution component to perform a braking action to stop the plunger pump. In the present invention, a braking system is arranged in the electric drive fracturing device, so that rapid braking of the electric drive fracturing device can be implemented, and emergency braking can be performed immediately when a problem such as bursting of a high-pressure manifold system occurs on site.
An electric drive fracturing device, comprising an electric drive fracturing device body and a brake, wherein the electric drive fracturing device body comprises an electric motor, a plunger pump, a first manifold, a second manifold, and a controller, and the brake comprises a brake trigger component and a brake execution component;
