1. A high-power turbine fracturing system, comprising:
a turbine engine;
a reduction gearbox coaxially arranged with and driven by the turbine engine;
a plunger pump connected to the reduction gearbox through a transmission shaft;
an auxiliary power system; and
a lubrication system powered by the auxiliary power system and comprising:
a first lubrication component for the turbine engine; and
a second lubrication component for the plunger pump and the reduction gearbox, the second lubrication component comprising a high-pressure lubrication unit and a low-pressure lubrication unit,
wherein:
the low-pressure lubrication unit is configured to pump low-pressure lubricating oil into a low-pressure oil line;
the low-pressure oil line is coupled to lubricate crankshaft bearings of the plunger pump, crosshead sliding rails of the plunger pump, bearings of the reduction gearbox, and gears of the reduction gearbox;
at an oil inlet of the low-pressure oil line, independent lubricating oil lines are separately arranged for the bearings of the reduction gearbox and the gears of the reduction gearbox;
the high-power turbine fracturing system further comprises an exhaust system connected to an exhaust port of the turbine engine; and
an exhaust end of the exhaust system is provided with a cap, the cap being configured to be hinged to the exhaust end of the exhaust system and to be driven by a capstan to rotate along the exhaust end of the exhaust system with a rotation angle between 0° and 90°.
