摘要： A gas blast interrupter has two hollow contact assemblies enclosed in a housing which can be filled with compressed air. A main exhaust valve, when opened, discharges compressed air from the interior of one contact assembly and thereby brings about separation of its contact making part from the contact making part of the second contact assembly. A further exhaust valve, when opened, discharges compressed air from the housing through the second contact assembly. The interrupter has a control valve having a first operative position in which compressed air is utilized to bring about the sequential opening of the main exhaust valve and the further exhaust valve and to close those valves after their contact making parts have separated, and having a second operative position in which compressed air is utilized to cause the contact making parts to engage and the contact assemblies and the housing to be filled with compressed air.

摘要： In the gas blast switch disclosed, a first contact member in a gas pressure chamber moves from an open position out of contact with a counter-contact member toward the forward position of the counter-contact member until it hits the latter and drives it backwards against the force of a spring. The counter-contact member forms a gas seal with a valve sleeve that the countercontact member pushes back against the force of a second spring. A spring actuated retaining mechanism holds the sleeve in the back position. When the first contact member is moved into the open position the sleeve is held and the first spring moves the counter-contact member away from the sleeve to open the seal. This releases a flow of gas from the chamber past the contact member. The gas flow strikes a vane in the retaining mechanism. The response of the vane is to release the sleeve. The second spring drives the thus released sleeve into engagement with the counter-contact member to cut off gas flow.

摘要： A circuit-interrupting device having extremely short switch-off times with a pressure chamber designed to contain a quenching gas under pressure and a pair of oppositely opposed contacts guided for a limited movement within the pressure chamber. A spring biases one of the contacts toward the other; and a quick-acting release device, such as a piston ring lock, holds the other contact against the first contact under high contact pressure when the interrupting device is in its switch-on position. The contact that is retained by the release device is biased only by the quenching gas in the switch-off direction. When the release device releases this contact, the two contacts separate from each other very rapidly. The contacts are sealed so that the quenching gas can not escape through the hollow bore of the contacts until they have separated. The release device may be provided with a suitable device to compensate for temperature fluctuations. The actuation of the release device may occur in dependence on the net current in the circuit, so that the separation of the tubular contacts occurs under minimum arc duration and, thus, with minimum switching effort.

摘要： An improved self-blasting compressed gas electric circuit breaker having a cylindrical member axially slidable on a fixed piston and forming a breaking chamber therebetween. The chamber contains the breaking gas and further comprises a plurality of recesses formed in one end of the cylindrical member with a like number of projections formed on the fixed piston complementary to the recesses. The recesses and projections preferably have a substantially truncated cone shape with a wide base. When a projection enters into a recess, the residual volume of the latter is reduced to a minimum upon the opening of the contacts. The recesses directly communicate with the cylindrical cavity defined between the known orifice structure and the fingers of the tulip-shaped movable contact and serve to break up the undesirable whirling motion of the gas heretofore formed in the known circuit breakers of this type.

摘要： A GAS-BLAST CIRCUIT INTERRUPTER OF THE PUFFER PISTON TYPE IS PROVIDED HAVING A PAIR OF VENTED SEPARABLE CONTACTS, WHICH MAKE VALVE-CLOSED ENGAGEMENT IN THE CLOSED POSITION. AN OPERATING LINKAGE IS PROVIDED WITH A LOST MOTION MECHANICAL CONNECTION BETWEEN THE PISTON MEANS AND THE MOVING CONTACT, SO THAT GAS PRESSURE IS BUILT UP PRIOR TO CONTACT PART. THE CONTACTS SEPARATE WITHIN AN INSULATING NOZZLE MEMBER, WHICH

GUIDES ALL OF THE GAS FLOW THROUGH BOTH VENTED CONTACTS, WHEN THEY PART DUE TO THE TAKEUP OF THE LOST MOTION.
