摘要： An ultrafast electrical (e.g., transfer, disconnect, etc.) switch that is simple, compact, does not require high energy to operate, ultralow loss, clean, and capable of being automatically reset. The invention includes a fast electromechanical switch having a drive mechanism integrated into the switching chamber. The integration of the drive mechanism into the switching chamber provides faster contact travel and therefore a faster switching operation. Additionally, the switching chamber is a self-contained environment that may consist of a high-pressure gas or a vacuum. The invention further includes an ultrafast disconnect switch. The invention generally is an integrated piezoelectric-actuator-based mechanical switching mechanism. The mechanism has a central piezoelectric actuator that extends to pull contacts inwards in order to obtain two disconnects within a millisecond or less. Surrounding the piezoelectric actuator is a polymer insulating shell and beyond the shell is the metallic conductor.

摘要： To improve cooling performances of quenching gas in a gas blast switch comprising a gas channel connecting an arcing region to a gas storage chamber delimited by radially opposite inner and outer walls and axially opposite first and second end walls, a flow guiding radial wall extends in the gas storage chamber spaced from each wall delimiting the chamber, an opening of the gas channel into the gas storage chamber through the first end wall faces a space between the flow guiding radial wall and the inner wall, the outer wall includes a deflecting portion protruding in the gas storage chamber and facing the second end wall, and at least part of the deflecting portion is offset from the flow guiding radial wall in an axial direction oriented from the gas channel towards the gas storage chamber.

摘要： The present disclosure may allow the movable base and the second movable contact driven in a dual-motion manner to be connected by a plurality of levers, and a force transferred to the movable base while the plurality of levers are in close contact with one another or released from the close contact may be transferred to the second movable contact, and thus a size of the levers may not be required to increase even when a stroke ratio between the movable base and the second movable contact increases, thereby having an effect capable of minimizing a size of the gas circuit breaker as well as appropriately controlling a stroke ratio between the movable base and the second movable contact.

摘要： A non-linear resistance film including an insulating material and a non-linear resistance material is provided on an inner surface of a grounded tank. The non-linear resistance film is formed to contain a larger amount of the non-linear resistance material on a side of a central conductor than on a side of the grounded tank. Accordingly, a gas insulated switchgear that can suppress partial discharge around metallic foreign matters and also can suppress inflow of charges from the grounded tank to the metallic foreign matters can be provided.

摘要： To provide a gas circuit breaker having a space-saving and highly reliable double motion mechanism with high design freedom. In a double motion mechanism of the gas circuit breaker, a driven side movable pin is communicated with a lever driven side hole cut in the opposite side with respect to a rotation axis of a lever. A round hole through which a driving side movable pin is inserted and an elongate hole through which the driven side movable pin is inserted are cut in the outside of the lever. A position retaining member to suppress rotation of the driving side movable pin about two axes vertical to a pin axis is provided. The driving side movable pin is moved in respective grooved cams with an operation of the driving side rod, to rotate the lever, drive the driven side connecting rod in an opposite direction to the driving side connecting rod, and drive the driven side arcing contact in an opposite direction to the driving side arcing contact.

摘要： A gas circuit breaker having a pair of contacts and a pair of exhaust conductors. An exhaust hole in the pair of exhaust conductors is provided with an insulation cover having an opening. The cover has a guide on an opening end on the side near the pair of contacts and an opening end on the side far from the pair of contacts respectively. The guide has an exhaust hole protective guide and a high-temperature gas passage dividing guide. A first gas flow passage is between an exhaust hole protective guide and a high-temperature gas passage dividing guide, and a second gas flow passage is between the high-temperature gas passage dividing guides. The first gas flow passage is narrower than the second gas flow passage. An end of the exhaust hole protective guide on the first gas flow passage side is projected toward the high-temperature gas passage dividing guide.
