How Electric Power Systems Run Industrial Fracturing Equipment
This patent describes an electrical power system for fracturing equipment, using separate high-voltage and low-voltage generators and switches to efficiently power a main motor and its auxiliary devices.
Original patent title: “Electrically-driven fracturing system”
This patent describes an electrical power system for fracturing equipment, using separate high-voltage and low-voltage generators and switches to efficiently power a main motor and its auxiliary devices. Granted in 2026.
Coverage
What does this patent actually cover?
The patent outlines an electrically-driven fracturing system that uses two distinct power sources. A powerful "main power generation device" supplies high voltage to the main "fracturing motor" through a high-voltage switch group. Separately, a less powerful "first auxiliary power generation device" provides lower voltage to a "fracturing auxiliary device" through a low-voltage switch group. This setup ensures that the heavy-duty motor receives ample power, while other components, like control systems or lighting, are powered appropriately. For example, a large gas turbine might power the main fracturing pump, while a smaller diesel generator or battery system powers the control cabin and fluid handling equipment.
The gap
What does this patent NOT cover?
- Does not cover fracturing systems powered solely by traditional internal combustion engines without electrical drive.
- Does not cover power systems where a single generator supplies both the main fracturing motor and auxiliary devices without distinct high and low voltage switch groups.
- Does not cover systems where the auxiliary power generation device has a rated power or voltage equal to or greater than the main power generation device.
- Does not cover the specific mechanical design of the fracturing pump, wellbore tools, or the chemical composition of fracturing fluids.
- Does not cover systems where the main power generation device is not connected to the fracturing motor, or the auxiliary device is not connected to the auxiliary power.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
Key facts
What made this novel
The noveltynoveltyThe requirement that an invention be different from anything publicly known before its priority date.Read more → lies in the specialized dual-power architecture: using separate main and auxiliary power generation devices with distinct voltage ratings and switch groups. This allows for optimized, segregated power delivery to the high-demand fracturing motor and its lower-demand auxiliary components, improving efficiency and control.
