Title: Innovations of Masami Kii in Circuit Interruption Technology
Introduction
Masami Kii is a prominent inventor based in Amagasaki, Japan, known for her significant contributions to circuit interruption technology. With a total of 15 patents to her name, Kii has developed innovative solutions that enhance the safety and efficiency of electrical systems.
Latest Patents
One of her latest patents is a circuit interrupter that features a pair of contacts which are relatively movable and detachable within an arc extinction chamber filled with a fluid. This design includes a chamber for storing the pressurized fluid in an arc space where the arc is formed during the operation of the contacts. The fluid is discharged from the chamber by opening a passage after the contacts have moved a specific distance, effectively interrupting the arc by puffing the fluid. Another notable patent is the puffer type circuit interrupter, which comprises a pair of contacts that can be moved to be detachable in a fluid for arc extinction. This invention includes a pressure chamber connected to the arc space, containing the fluid whose pressure is raised in the arc space. The fluid passage remains closed until one contact is moved a specific distance, at which point it opens to discharge the fluid, thereby performing arc extinction through the puffing of the fluid.
