    摘要: A gas-blast load-break switch comprises a pressure storage chamber for storing pressure of arc-extinguishing gas with arc energy generated by the disconnection between contacts, and a suction chamber including a piston which is moved in connection with the cut-off movement of the movable contact. A gas flowing device is provided such that the pressure raised by the arc energy is stored in the pressure storage chamber before communicating the pressure storage chamber and the suction chamber and a gas chamber formed on the opposite side of the piston from the suction chamber. The volume of the gas chamber is greater than that of the pressure storage chamber and the suction chamber, and the distance of piston movement in the suction chamber is longer than the contact length when the movable contact is thrown into the fixed contact.

    摘要: An electric power circuit breaker includes two switching elements which can move, relative to each other, in an extinguishing gas and which contain, in each case, at least one main current contact and at least one arcing contact. A cylindrical coil is connected between the arcing contact and the main current contact of one of the two switching elements. This coil is provided with a ferromagnetic core, as a result of which the magnetic field of the coil exhibits a high field strength at the position occupied by an arc-commutating ring which is connected to the coil. In this circuit breaker, the commutation of heavy currents from the main current path to the coil path is accomplished in a reliable manner at all times and by simple means. This is achieved when the core is installed in a manner permitting its displacement along the axis of the coil. When the circuit breaker is in the circuit making position the core passes through no more than a portion of the interior of the coil. It closes off the interior of the coil and is flush with the arc-commutating ring when the circuit breaker is in the current breaking position.

    摘要: A high voltage power switch has a stationary contact and an axially displaceable contact, with a nozzle-like orifice through which quenching gas flows during the disconnecting process from a quenching chamber to an expansion chamber, and a coil through which the disconnect current flows after the commutation of the disconnect arc to an annular contact. Between the stationary contact and the annular contact at least one exhaust channel is provided, whereby prior to the commutation of the disconnect arc to the annular contact, the quenching gas heated by the disconnect arc is removed from the contact-break path and conducted into a discharge chamber. This feature enables the dielectric strength of the arc path to be increased by simple means, while simultaneously effecting a commutation of the disconnect arc from the stationary arcing contact to the annular contact in a constantly secure manner.

    摘要: A self-extinguishing circuit interrupter wherein a pair of separable contacts is disposed within an arc extinguishing gas. Energy of an electric arc established between the separated contacts is utilized to increase the pressure of the arc extinguishing gas, and the high pressure gas thus generated is introduced into a pressure chamber to be stored therein. When the arc current approaches zero, the high pressure gas within the pressure chamber is puffed to the arc to extinguish it. A plurality of pressure chambers are axially disposed, i.e., in the direction in which the movable contact moves, thereby improving the arc extinguishing capability of the circuit interrupter.
