Latest Patents

Two of Wada's latest patents exemplify his ingenuity in electrical systems. The first patent details a sophisticated switchgear device. This switchgear features a housing filled with arc extinguishing gas, designed to manage the arcing region between a pair of separable contacts during operation. As the contacts separate, an electric arc is generated, and the device effectively utilizes a cylindrical wall and insulating nozzle to store pressurized arc extinguishing gas. This gas is crucial for suppressing the arc, as it flows through the nozzle to mitigate the effects of the electric discharge. Additionally, a strategically placed magnet generates a magnetic field that helps control the arc's behavior upon interruption, further ensuring circuit safety.

The second patent introduces a high-speed current limiting circuit breaker. This innovative breaker incorporates a self-recovery type current limiting element alongside a parallel resistance and a standard circuit breaker. The design includes a fault voltage detector to streamline the detection of voltage fluctuations. When a fault occurs, the electromagnetic repulsion coil engages to break the circuit, effectively managing fault currents and preventing damage to the electrical system.
