摘要： The electrical switch according to the present invention has first and second electrical contacts each of which functions as both male and female contacts. More specifically, the first electrical contact includes a first electrical contact member having outer and inner perimeters. The second electrical contact includes a second electrical contact member also having outer and inner perimeters. A contact probe is secured to the second electrical contact member within the inner perimeter thereof. Thus, when the first electrical contact is in electrical contact with the second electrical contact, the inner perimeter of the second electrical contact member electrically contacts the outer perimeter of the first electrical contact member and the contact probe electrically contacts the inner perimeter of the first electrical contact member.

摘要： A high tension or medium tension circuit breaker having abutting arcing contacts. The circuit breaker includes a gastight insulating case filled with a gas having good dielectric properties. The case contains a stationary arcing contact; a moving arcing contact driven by a drive rod actuated by a mechanism outside the case. A blast chamber is defined by a piston integral with the moving arcing contact, slidably received in a fixed cylinder terminating in a blast nozzle, the cylinder and a ring. The circuit breaker further includes a lost motion mechanism to enable the drive rod to move over a given length in the circuit breaker opening direction without driving the moving arcing contact away from the fixed arcing contact.

摘要： A pole-unit of a gas-blast electrical circuit breaker comprises a tranverse partition made of injected insulating plastic material which at the same time performs guiding of the movable contact which passes through it. The injected material part bears an O-ring ensuring tightness with the casing and a one-way check valve of gas flow orifices arranged in the transverse partition. The gas-blast piston securedly united to the movable contact is also made of injected material and it comprises housing and clipping means of the puffer nozzle securedly fixed to the piston. A scraper seal in the form of a split segment is housed in a circumferential groove arranged in the injected part of the piston. The electrical connection between the movable contact rod and a flexible current supply insert is achieved by a braided strip extending in the form of a half-loop in a transverse plane to the pole-unit.

摘要： An insulative tube (93) of a switch is molded with an inserted tubular condutor (15), and a sliding contact (14) provided on outer surface of a piston (7) slides on an inner surface of the tubular conductor (15); the insulative tube (3) is thereby reinforced against the pressure of an insulation gas sealed in the insulative tube (3). The piston (7) and the tubular conductor (15) are electrically connected in a stable manner and undesirable tottering of moving contacts (8), (16) mounted on the piston (7) can be prevented.

摘要： An internal combustion electrical circuit breaker comprising at least one: (a) insulating cylinder; (b) pair of electrical conductors penetrating the cylinder approximately perpendicular to its longitudinal axis at a distance from both cylinder's plane sides; (c) conducting hollow piston contacting the conductors and an insulating pipe at its open portion, which pipe extends within that axis and penetrates the cylinder's first plane side; (d) arcing chamber extending from that plane side to the conductors; (e) pair of arcing blades within the arcing chamber at a distance from the conductors, piston and pipe; (f) valves within the pipe and first plane side, communicating with the arcing chamber and hollow piston; (g) combustion chamber extending from the piston's closed portion to the cylinder's second plane side; and (h) ignition, gas injection and valve means within the plane side and communicating with the combustion chamber.When igniting a fuel-oxygen mixture within the combustion chamber, the piston is propelled into the arcing chamber and onto the pipe therein, while the gases within hollow piston and arcing chamber blow across the sparks developing between conductors, piston and arcing blades. This circuit breaker is re-set by injecting compressed gas through the pipe, thereby forcing the piston into the combustion chamber and back onto the conductors, while expelling combustion products and injecting a combustible gas mixture, preferably a stoichiometric (1:2) oxygen/hydrogen mixture into that chamber, which is lined with a material suppressing heat damage and catalytic recombination of the gas mixture therein.

摘要： A disconnect switch is disclosed having a puffer interrupter electrically connected with and operated by a knife switch or fused disconnect switch. A puffer interrupter includes a divided pressure chamber having at least one exterior wall which is flexible and responsive to the pressure therein. A fixed tubular electrical contact is carried by a fixed interior wall within the puffer interrupter housing so as to establish flow communication through the fixed interior wall. A floating electrical contact is carried by the flexible wall and is adapted to engage and disengage from the fixed electrical contact in response to movement of the flexible wall. A snap spring biases the floating contact away from the fixed contact during arc interruption. The knife switch carries a camming member which electrically connects the knife switch to the floating contact and which overcomes the snap spring in such a manner that the knife switch is electrically disconnected from the load before the puffer interrupter is discharged and is electrically connected to the load after the puffer interrupter is closed. Several embodiments of the abutting ends of the fixed and floating contacts and pressure chamber walls are illustrated.

摘要： To provide a high-voltage switch which can switch off in a very short time, namely in a half-period, rapid severing of the isolating screws (36) is utilized, and the high-voltage switch is designed so that the switch-off and switch-on device contains at least one isolating screw (36) by means of which a prestressed rod (28) connected to the movable contact of the high-voltage switch can be released. The half-period high-voltage switch according to the invention is used appropriately in switching systems where the half-period high-voltage switch is connected in series with at least one power circuit-breaker. The advantage is to be seen especially in the use of the high-voltage switch in switching systems where it permits a limited short-circuit cut-out capacity.

摘要： A puffer type circuit breaker is provided with a pump means consisting of a piston and a cylinder for producing a blast of arc-extinguishing gas. The movable arcing contact of the circuit breaker and the cylinder are connected to an operating device via a rod axially displaceable through an opening in the piston. In the piston there is arranged a check valve, which upon closing of the breaker opens for subsequent filling of the pump chamber with arc-extinguishing gas. The check valve comprises a guiding sleeve of a ductile material (e.g. polyetrafluoro ethylene), which sealingly surrounds the rod and is fixed with a certain axial mobility in the opening in the piston arranged for the rod. The sleeve controls (or is fixedly connected to) the movable valve means of the check valve and, in addition, serves as a seal and a bearing between the rod and the piston.

摘要： A DC circuit breaker of the type using a blown arc-extinguishing gas is disclosed which allows for reliable fast interruption of DC currents through the provision of arc extension current paths. The extension current paths are relatively long and are bent after the incidence of the arc-extinguishing gas on the arc. The arc is formed to extend for a long distance in a loop configuration. An auxiliary electrode short-circuits the extended arc with one auxiliary electrode being provided for each extension current path.
