    摘要: A circuit breaker comprising at least two electrically seriesconnected puffer type breaking units which extinguish an arc produced between the contactors by blowing a high pressure arcextinguishing gas produced by compression simultaneously with the start of breaking action against the arc and which are driven by an electromagnetic driving device, consisting of a primary coil and a shorting ring or shorting coil electromagnetically coupled to the primary coil, into which a current to be broken is diverted at the time of breakage.

    摘要: A gas breaker wherein an electromagnetic force is generated between a primary coil fixed to an operating rod manipulating a movable contact element and an end ring or a short ring fixed to a floating puffer piston slidably supported against said operating rod, said floating puffer piston being driven to compress arc-extinguishing gas in said puffer cylinder by an electromagnetic repulsive force and an arc is extinguished by compressed arc extinguishing gas which is blasted to the contact element. A movement of the puffer piston for compressing arcextinguishing gas is shut off from that of the operating rod, so that the electromagnetic repulsive force is utilized for compression of the arc-extinguishing gas in the puffer cylinder, whereby the electromagnetic force is not effected to the operating rod, thus resulting in making the control system for the operating rod more compact.

    摘要: In a gas-blast switch with a compression device to produce a quenching gas blast, in order to make the magnetic effect of the break current available already at the beginning of the cut-off movement, a compression chamber and a piston-cylinder system form an energy accumulator. A movable element of the piston-cylinder system is mechanically linked with an armature, which is axially moved by the magnetic field of a stator, which field is excited by the break current. The armature and the stator are arranged in such a way that the magnetic field already causes the armature to move.

    摘要: In a magnetic puffer type gas circuit breaker including an electromagnetic coil through which a current to be interrupted flows during the breaking operation, and an electromagnetic repulsive member which produces an electromagnetic repulsive force in cooperation with the electromagnetic coil and drives movable parts of a breaking portion of the apparatus, the electromagnetic repulsive member is so arranged that the electromagnetic neutral position of the electromagnetic repulsive member within the electromagnetic coil at the time when the breaking portion has been closed deviates on the closing side with respect to the electromagnetic center of the electromagnetic coil. Further, the characteristics of the electromagnetic repulsive forces between the electromagnetic coil and the electromagnetic repulsive member are so set that their absolute values become smaller on the closing side than on the breaking side with respect to the point at which the electromagnetic center of the electromagnetic coil and the electromagnetic neutral position of the electromagnetic repulsive member are coincident.

    摘要: A fluid-blast piston-type circuit interrupter utilizes two stationary accelerating coils and one moving accelerating coil carried by a fluid-driving piston assembly. During the opening operation, the series fault current is inserted serially into the three accelerating coils, and their magnetic attraction and repulsion forces assist the operating mechanism to move the fluid-driving piston assembly, and thereby to drive fluid, such as sulfur-hexafluoride (SF6) gas, through the established arc drawn within an orifice member to effect its extinction.

    摘要: In a gas-blast switch with a compression device with a compression piston and a compression cylinder, at least one of which can be moved by the drive during the cut-off process, starting from a cut-in position, reducing a compression space delimited by them, the initial quenching gas pressure is increased in that the compression piston is moved toward the compression cylinder in advance. In order to take advantage of the magnetic effect of the break current, an armature which can be moved by the magnetic field of a stator which can be excited by the break current is provided, producing a pressure influence causing the advance movement of the compression piston via a compression chamber.
