Latest Patents

Liu's latest patents include a "Repair device for burnout of stator iron core in giant hydraulic turbine generator, and repair method thereof." This invention provides a solution for the burnout of the stator iron core in giant hydraulic turbine generators. The device features toothed plates, ventilation slots, binding holes, ventilation holes, and binding cables. Each toothed plate is designed to match a burnout area in the middle of the iron core, ensuring that the ends of the toothed plate contact plate assemblies. The binding cables are used to tightly bind the toothed plates and coil bars into an integral structure. This innovation effectively addresses the long re-lamination cycle issue that affects power generation during flood seasons.

Another significant patent is the "Method and standard module for amplifying pulsed power." This invention outlines a method for amplifying pulsed power through the combined action of a LASER mode of a crystal medium, a carrier multiplication amplification mode of a semiconductor medium, and a plasma breakdown amplification mode of a gas medium. The process involves converting electric power into optical power, amplifying it, and then converting it back into electric power using a photoelectric conversion and amplification device. This method allows for the generation of timing-synchronized high-power electric pulses, which can be outputted directly or distributed across multiple channels.
