Title: Innovations of Yoshihiko Hirano
Introduction
Yoshihiko Hirano is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of gas insulation technology, holding a total of 4 patents. His work focuses on enhancing the efficiency and safety of electrical systems through innovative designs.
Latest Patents
Hirano's latest patents include a gas insulation apparatus and gas insulated switchgear. The gas insulation apparatus is designed to include a high-voltage unit, zeolite, and insulation gas within a closed vessel. The insulation gas can be CO gas or a gas that primarily consists of CO gas. The zeolite is contained in a zeolite case and is placed under an insulation gas atmosphere, allowing CO to be adsorbed on the zeolite before the apparatus is utilized.
The gas insulated switchgear features electrical contacts situated inside a sealed vessel filled with an arc extinguishing gas. When electrical current flows, the contacts remain in contact to allow electricity to pass. Upon interruption of the current, the contacts separate, producing an arc discharge in the extinguishing gas, which is then extinguished. The arc extinguishing gas can be a mixed gas, primarily composed of N gas and CH gas, with a CH content of at least 30%. Alternatively, it may consist of CO gas and CH gas, with a CH content of at least 5%.
