摘要： A gas circuit breaker that includes: a first tank filled with an insulating gas; a fixed contact provided inside the first tank; a movable contact provided inside the first tank; a nozzle that ejects the insulating gas toward the fixed contact when the movable contact moves in a first direction; a cylindrical body that guides the gas ejected from the nozzle in a second direction; and a second tank connected to the first tank in the second direction. The movable contact is movable between a position in contact with the fixed contact and a position separated from the fixed contact. The first direction is a direction in which the movable contact moves from the position in contact with the fixed contact to the position separated from the fixed contact. The second direction is a direction opposite to the first direction.

摘要： A power circuit breaker unit has first and second arcing contact pieces. A contact gap is formed between the arcing contact pieces. A switch gas channel of the circuit breaker unit joins the contact gap to the surrounding area of the circuit breaker unit for removing a switch gas from the contact gap. Several barriers that increase a flow resistance are arranged successively, spaced from one another, in the switch gas channel. At least one of the barriers is arranged between a first pipe section, which is surrounded by a second pipe section, and the second pipe section.

摘要： A puffer-type gas blast circuit breaker is capable of restraining reduction in creepage insulation resistance of an insulating support and an insulating rod due to insulating gas of high temperature. An electrode section is mounted on a stationary member supported on an insulating support, and a stationary side arc contact and moving side arc contact are disposed facing each other to contact and separate; a hollow piston rod and an insulating rod are connected to the moving side arc contact, and inserted in a stationary member body portion; and a gas flow blocking member is mounted on an end of the piston rod to prevent an insulating gas heated and coming to the stationary side from getting into the insulating rod side. The stationary member body portion is formed cylindrical so that a gap between the body portion of the stationary member and the gas flow blocking member is minimized.

摘要： A puffer type gas circuit breaker having at least one pair of a stationary contact and a movable contact capable of being separated from each other, a pressure producing section including a puffer cylinder and a puffer piston. The puffer cylinder is connected to the movable contact and serves to compress an arc extinguishing gas blown to an arc generated between the contacts at the time of current breaking. The breaker also has a cover surrounding the movable contact, an insulated nozzle extending from the puffer cylinder and surrounding the cover and the stationary contact to form a flow passage through which the compressed gas is supplied from the puffer cylinder to the generated arc, and a flow straightening member provided in said flow passage. The flow straightening member extends from the puffer cylinder and is mounted on the cover, and the flow passage has an expanded section having a gas flow sectional area larger than that of the section of the flow passage upstream of the expanded section.
