Abstract: A circuit breaker bridging contact is constructed as a U-shaped member having L-shaped arms to more efficiently utilize electrodynamic forces to achieve current limiting action. Upon circuit opening parallel arcs re drawn between the bridging contacts and the spaced stationary contacts. The currents flowing in these arcs are in directions opposite to current flowing in those portions of the bridging contact arms that are parallel to the arcs and relatively close thereto, so that electrodynamic forces tend to drive the arcs away from the separating contacts. Speed of contact separation is improved by having the web of the bridging contact in close proximity and parallel to a rigidly held conductor section through which current flows in a direction opposite to that of current flowing through the bridging contact web.

Abstract: A current limiting circuit breaker is constructed to achieve more rapid tripping in the medium fault current range by utilizing a magnetic tripping device which imparts physical motion to the movable contact under particular fault current conditions. In the lowest fault current range above the thermal tripping range the magnetic tripping unit automatically operates or releases the spring operating mechanism thereby causing contact separation. As fault current increases the magnetic tripping means is effective to assist the operating mechanism to physically move the movable contact, and at still higher currents the magnetic tripping means moves the movable contact to its fully open position before any movement is imparted to the movable contact by the spring operating mechanism. As fault currents increase still further, electrodynamic forces assist the magnetic means to physically move the movable contacts, and in the very highest fault current range electrodynamic operation moves the movable contact essentially to its fully opened position, before the magnetic trip means for the operating mechanism is active in moving the movable contact.

Abstract: The pressures of a low-pressure and high-pressure region of a two-pressure gas circuit breaker are applied to pistons carried on a common rod so that the pistons and rod move to a predetermined position when the pressure difference between the two pressure regions is below a given value. The motion of the rod turns on a compressor which operates until a desired pressure ratio is obtained.

Abstract: A high-speed gas blast circuit breaker in which SF6 is used as the mechanical drive for the movable contact and as the dielectric medium for maintaining a high dielectric between the open contacts and for extinguishing arcs. Two or three movable elements are used; an annular movable contact and a cutoff valve and, in some cases, a follower contact. The two elements may be incorporated into one movable body. Each of the movable elements have radially extending surfaces defining pistons so that they may be moved by control air pressure. The movable contact serves as an annular seal in a barrier which separates a high-pressure region from a low-pressure region when the contact is closed. The movable contact acts in the manner of a cork so that, when the seal is broken, the contact is accelerated toward its open position, and fluid from the high-pressure side flows through the annular gap formed and through the arc in its passage to the lowpressure side. The apparatus is mounted in a suitable switch gear enclosure.

Abstract: A pressurized SF6 gas interrupter structure is used with a conventional mechanical circuit breaker operating mechanism. The operating mechanism is not opposed by high gas pressure, used for arc interruption, while the high gas pressure is used for high initial contact parting speeds. Maximum gas flow is obtained during contact opening for arc extinction purposes, while gas flow is restricted during closing to conserve the supply of pressurized gas.

Abstract: An arrangement for supporting electrical switches, buses and the like in a high power distribution system includes a first insulator column capacitively graded along its length so as to provide a substantially uniform voltage distribution from the energized switch or bus, etc., along the length of the column, and a second insulator column to provide the mechanical support for the electrical apparatus and for the first column. When so arranged, the two columns present an overall hourglass appearance and simultaneously exhibit desirable electrical and structural characteristics.

Abstract: A movable baffle for the interrupter of an SF6 circuit breaker in which the baffle is movable to a position surrounding the stationary contact by gas pressure when a blast valve is opened and the circuit breaker is to be opened. The baffle, when engaging the stationary contact, defines a gas channel to conduct gas through the arc interruption region. A spring bias moves the baffle away from the stationary contact and to a favorable dielectric position when the interrupter contacts are open.

Abstract: Terminal straps to which cartridge fuses are bolt or screw connected are provided with locating means which establish predetermined operative positions for a reject member securable to one or more of the terminal straps. When the reject member is not present, fuses of relatively high intermediate and low ratings may be mounted to the terminal straps. When the reject member is mounted in one of its operative positions, only the low rated fuse may be mounted to the terminal straps, and when the reject member is in another one of its operative positions, both the low and intermediate rated fuses may be mounted to the terminal straps, but high rated fuses may not be mounted thereto.
