Latest Patents
Watanabe's latest patents include a hydraulic pressure actuating apparatus for circuit breakers and a grounding switch gear device. The hydraulic pressure actuating apparatus features a moving contact and a stationary contact for turning on and off current. It utilizes a shaft connected to a piston within a cylinder, controlled by a directional control valve that exchanges oil pressure to actuate the piston. This design ensures that even if a drawback occurs in the pilot valves, the actuating time remains unaffected. The grounding switch gear device consists of a puffer chamber formed by a puffer cylinder and a fixed piston. This innovative design allows for the continuous blowing out of gas between electrodes, effectively prolonging the interruptable arc time span without increasing the size of the circuit interrupting unit.
