He has made significant contributions to the field of electrical engineering, particularly in the development of advanced materials and circuit-breaking technologies. With a total of 4 patents, his work has had a considerable impact on the industry.

Latest Patents

One of his latest patents is a method for manufacturing electrode material for vacuum circuit breakers. This invention provides a Cu-Cr alloy electrode material by heating a mixture of Cu and Cr materials at a predetermined ratio until it is entirely melted. The molten metal is then quenched to precipitate fine Cr particles in a Cu base. This process prevents defects such as voids in the structure and ensures a fine alloy structure by avoiding issues related to oxide films on the surface of the Cr particles.

Another significant patent is for a circuit-breaking apparatus. This apparatus consists of an insulating housing with first and second electrodes located at both ends. It includes a detonator in the first electrode, which is connected to a lead for supplying electric current. The conductor within the housing features a fixed portion connected to the first electrode and a circuit-breaking rod with narrow portions at both ends. This design ensures that the circuit-breaking function is reliably maintained and allows for easy determination of whether a circuit-breaking operation has been performed.
