摘要： A compressed-gas circuit breaker possesses two contact members (1, 2), which move relative to one another, and a nozzle (7), which is made of dielectric material and is attached to a first (2) member of the two contact members. The constriction (8) of the nozzle (7) which is made of dielectric material, separates a compression-space (9) from an expansion-space (15), and the compressed gas used for extinguishing the arc which occurs on operating the circuit breaker flows through this constriction. An insert (13), designed in the shape of an annulus, is provided at the nozzle constriction (8). The design of the nozzle (7), which is made of dielectric material, is such that it can be exposed to a high thermal loading in the region of its constriction, while, at the same time, high voltages can be held in the breaker-gap, without the occurrence of instances of arcing-over. This object is achieved by arranging the insert (13) to be electrically isolated with respect to the two contact members (1, 2) the insert exhibits a first capacitance with respect to the first contact member (2) and a second capacitance with respect to the second contact member (1). The magnitudes of the capacitances are chosen, by suitable arrangement and dimensioning of the insert (13), so that the electric field in the region of the nozzle constriction (8) is displaced at least partially from the surface of the nozzle, into the compression-space (9) and into the expansion-space (15).

摘要： A compression piston switch is provided with two switching parts which are mutually axially displaceable. The switch also has a device which is connected to a first one of the two switching parts for guiding a quenching gas flow. The quenching gas, which is used for quenching a switching arc, flows through first and second constrictions in the device from a compression into an expansion space. The first constriction of the device is provided by an annular part of a conductive material.In this switch, the dielectric strengthening of the quenching zone is increased by preventing, to a large extent, the pushing together of the electric field between the device and the first switching part. Such a switch is particularly distinguished by reliable switching of high voltages in the case of a short circuit.

摘要： An electrical power switch operating with a pressurized gas for actuating the switch contacts and also providing a quenching action in which the arc is lengthened and extinguished includes a container in which the pressurized gas is stored, the outlet from this container being located adjacent the junction area between a plurality of contact fingers in fixed position and a movable contact member that also includes a valve member for closing off the gas outlet from the container when the switch contacts are closed. When the movable contact is released for initiating an opening operation of the contacts, the pressure of the gas stored in the container forces the valve open thus releasing the gas for blasting the arc drawn between the contacts. The gas enters an annular chamber surrounding the junction line of the contacts which includes two half-turn helical travel rails of different radius and opposite winding sense to which the feet of the arc are transferred from the contacts and travel downward and into a group of circumferentially spaced nozzles in which the arc is further lengthened.

摘要： In a high-voltage power switch having a movable contact and at least one other contact, wherein the contacts define a quenching path in which an arc burns, a piston/cylinder compression device in which fresh quenching gas is condensed, and a heating volume in which quenching gas is stored and compressed by the arc as a result of heating, quenching gas compressed during a switching process is blown into the quenching path and removed through a nozzle into an expansion space. So that the blowing of the arc is nearly independent of the intensity of the current to be interrupted and, in addition, an increase in the quenching capacity can be attained by means of a supply of fresh quenching gas, the movable contact is rigidly connected to the piston, which changes the volume of a compression space. The compression space and the heating volume open into a common annular duct. This annular duct is a part of a mixing device for hot and cold quenching gas and connects the compression space and the heating volume to the quenching path.

摘要： A high voltage power switch for alternating current has a stationary, hollow contact, an axially displaceable contact, a nozzle through which compressed gas is directed into an expansion chamber, and a cylindrical coil. The coil is connected at one of its ends with a first part of the hollow contact, and at its other end with a second part of the stationary contact. In a switch of this type, the disconnect capacity is improved by an increased exchange of gas between the arc and the surrounding compressed gas, while the dimensions of the coil connected with the hollow contact and the magnitude of the flow of compressed gas are relatively small. These features are obtained by configuring the first part of the stationary contact as a nozzle, and providing a compression device, actuated by the contacts, to produce a flow of compressed gas of a magnitude so that the arc is commutated from the first part to the second part of the contact within a period of time that is short compared with the duration of the half-wave of the current, prior to the time the current changes polarity.

摘要： An electrical switch for large currents is disclosed in which an electric arc generated during separation of contact members is exposed to blow-out by a magnetic field generated by current flow in a looped-region of one of the contact members. The switch includes at least two rotationally symmetric contact pieces, at least one of which has a plurality of contact elements arranged in an annular configuration in the circumferential direction. The contact elements include a looped-region which generates the magnetic field to which the electric arc is exposed. The contact elements may consist of a plurality of contact fingers accommodated by a contact piece, or may consist of a plurality of contact bars integrally formed with a contact piece. The contact elements, which extend substantially in the make/break direction of the switch, may be spring loaded or may be supported in a spring-loaded fashion.

摘要： An electrical compression switch operating with a compressed gaseous arc quenching medium comprises a switch chamber containing a pair of disengageable contacts one of which is a pin contact and the other a tubular nozzle contact surrounded by a tubular nozzle made from insulating material engageable with the pin contact and which surrounds the tubular nozzle contact in spaced relation to form a compression chamber. An expansion chamber is secured to the end of the tubular nozzle of insulating material and a differential piston operates within the latter and also within the compression chamber. A switch drive effects movement of the pin contact and differential piston considered as one unit relative to the tubular nozzle contact, the tubular nozzle of insulating material and the quenching medium expansion chamber considered an another unit to effect disengagement of the switch contacts as well as relative movement between the differential piston and tubular nozzle of insulating material in such direction as to decrease the volume of the compression chamber and thereby increase the pressure of the quenching medium at the arc which together with the thermal energy of the arc assists in the switch drive and also assists in arc extinction.

摘要： A gas-blast breaker with two contact members which are movable relative to one another. Each contact member is provided with a respective sparking contact. The contacts communicate with a cylindrical compression chamber whose volume varies as a function of the movement of the contact members and which is filled pressurized gas. A channel leading into a quenching zone between the sparking contacts extends into a first one of the two end faces of the compression chamber. A second one of the two end faces is bounded by a piston which is displaceable along the cylinder axis of the compression chamber and which is subjected to the action of a tensioned spring. The circuit breaker is suited for reliably interrupting both small and large currents, with a comparatively weak and simple drive mechanism for the movable contact member. The piston interacts with a fixed stop which is arranged such that the movement of the piston which is subjected to the action of the tensioned spring is blocked, below a predetermined first gas pressure in the compression chamber, against the movement of one of the contact members which is moved upon the occurrence of a breaking operation in the circuit breaker.
