Operation method of a turbine fracturing device and a turbine fracturing device

An operation method of a turbine fracturing device, the turbine fracturing device comprising a turbine engine, a speed reducer, a brake mechanism, and a fracturing pump, the method comprising:

• driving, by the turbine engine, the fracturing pump to perform a fracturing operation through the speed reducer so as to keep the fracturing pump in an operating state, the fracturing pump being configured to suck a fluid of a first pressure and discharge a fluid of a second pressure, the second pressure being greater than the first pressure;
• triggering an overpressure instruction when a pressure of the fluid of the second pressure discharged by the fracturing pump is greater than an overpressure protection value, wherein the overpressure instruction triggers an idling instruction;
• and
• in response to the idling instruction, entering, by the turbine engine, an idling state and triggering a brake operation so as to keep the fracturing pump in a non-operating state.

• in response to an idling instruction, the turbine engine entering an idling state and triggering a brake operation so as to keep the fracturing pump in a non-operating state;
• and
• stopping the fracturing operation in response to a stop instruction and stopping the turbine fracturing device, wherein the stop instruction triggers the idling instruction.
