An electrical switch includes a pivotally supported blade, a toggle mechanism, and an operating mechanism. The operating mechanism is drivable in a first direction to pivot the blade about a first axis and toward a closed blade position. When pivoting toward the closed blade position, the toggle mechanism inhibits the blade from pivoting about a second axis. Upon reaching the closed blade position, continued motion of the operating mechanism in the first direction causes the toggle mechanism to pivot the blade about the second axis toward a closed contact position. In the closed contact position, the blade contacts at least one blade contact to electrically connect the blade and a first electrical terminal. | ||||||

33 | Switchable lightning arrester system | US10677010 | 2003-09-30 | US07245473B2 | 2007-07-17 | Michael L. Prelec |
The switchable lightning-arrester system has a safety-switchable connector (10), which, for differing power-line features, can include optionally a counter-lever safety connector (14), a slide safety connector (40), a hinged safety connector (56) and a pivot safety connector (67) intermediate a power line (11) and a lightning arrester (1) for on-spot disconnection to protect workers from self-destructing arresters when changing lightning arresters or working on damaged lines without costly, time-consuming and power-disruptive shutdown of power lines. This is highly important because the lightning arresters are changed and repair work is done on damaged lines as quickly after self-destruction from lightning surges as possible requiring the change and repair. The safety-switchable connectors are made to be operable and changeable from a safe distance remotely, which is preferably from a ground position near a light pole, a transformer or other line support (9). Many line-worker lives have been injured or lost in the past without this safety-switchable connector. | ||||||
34 | Switch with improved protection from ice conditions | US11299269 | 2005-12-12 | US07223928B2 | 2007-05-29 | William W Riopka; Terrence S. Kerr |
An arrangement is provided to protect an electrical switch from the deleterious effects of ice formation that inhibits switch operation. In a preferred arrangement, an ice shield is provided that protects the current-carrying contact structures and other operative elements of the switch from ice buildups. In one specific arrangement, as the switch is moved from the open position to the closed position, the ice shield moves away from the contact structure of a moving contact of the switch to permit unfettered engagement with a stationary contact structure of the switch. | ||||||
35 | Transformer system provided with a decoupling system | US09508750 | 2000-05-10 | US06535097B1 | 2003-03-18 | Olaf Brockmann; Joerg Pscheidl |
To allow simple performance of a voltage test of a high-voltage system, a transformer system having a transformer housing (1) that receives a voltage converter (4) and having an electrical terminal (6) electrically connected to the voltage converter (4) and extended out of the transformer housing (1) for connecting the transformer system to a high- or medium-voltage system, is improved in that a decoupling system (12, 25) actuatable from outside the transformer housing (1) for temporarily interrupting the electrical connection between the voltage converter (4) and the first terminal (6) is disposed in the transformer housing (1). For performing a direct voltage test, the transformer system of the invention no longer has to be detached from the high-voltage system. | ||||||
36 | Positive locking mechanism for in-line switch | US836763 | 1997-05-05 | US5942723A | 1999-08-24 | Rocco Valentino Laricchia |
An isolating switch for an electric power line including a sub-assembly made up of two electrically conductive and pieces interconnected by at least one insulator. The end pieces have respective aligned grooves for registry with the electric power line, and securing members for permanently securing the end pieces to the electric power line. The sub-assembly is provided with two keeper bars for mounting the sub-assembly to the power line prior to permanently securing the end pieces to the power line. Each of the keeper bars is pivotally mounted on a respective one of the end pieces and is pivotable manually between a first position in which the keeper bar is completely clear of the groove and a second position in which the keeper bar extends across the groove to retain the sub-assembly on the power line. A detent member is provided on each end piece for cooperation with the respective keeper bar, and a spring member urges the keeper bar and detent member into mutual engagement when the keeper bar is in the second position to retain the keeper bar in the second position. | ||||||

The apparatus includes contact blades at different elevations on a utility pole rotatable between electrical connection and disconnection positions vis-a-vis contact members. To rotate the contact blades, an electromechanical linear actuator extends a clevis and crank arm to rotate a vertically extending shaft coupled to another crank and a lever arm to rotate the insulators on which the contact blades are mounted. The linear actuators are carried by support structure high on the utility pole and, by rotating the vertical shafts, the insulators and contact blades at each phase are simultaneously rotated. | ||||||
38 | Contact assembly for high-voltage switch | US92026 | 1987-09-01 | US4795869A | 1989-01-03 | Christopher D. Roman; Dean M. Czuma |
A contact assembly is provided for a high-voltage switch. The contact assembly includes one or more contact members that cooperate with a contact element. The arrangement of the contact members is such that an interference fit results with the contact element and one or more of the contact members are displaced. To provide operation of the contact assembly in ice-forming environments, facilities are provided to prevent the ingress of moisture and the formation of ice in the space required for displacement of the appropriate one or more contact members. Of course, if ice were allowed to occupy the space required for displacement of the one or more contact members, due to the relatively incompressible nature of ice, appropriate contact engagement would be inhibited since displacement of the one or more contact members would be unable to occur when engaged by the contact element. In a specific arrangement, the contact assembly includes a contact support structure which carries the contact members. A filler element is provided between the contact support structure and the contact members that are required to be displaceable. The filler element is deformable and/or compressible in response to the displacement of the contact member. Additionally, the filler element is impervious to the ingress of moisture or the formation of ice crystals and retains its flexiblity under ice-forming conditions. | ||||||

A new and improved apparatus is provided to permit a live or hot electrical power line to be cut in the field for line service or other purposes. The apparatus is connected at each end to the line at positions spanning the site of the cut. The attached end portions are then moved closer to each other, easing the tension on the portion of the line to be cut. The apparatus is then connected to the live line with jumper cables, forming a parallel electric circuit. The line is then cut and a cut end tied back. Flow of current through the apparatus is broken. An interrupter in the apparatus suppresses any arc which may tend to form. | ||||||
40 | Automatic resetting control circuit for air switch operator | US820039 | 1977-07-29 | US4128856A | 1978-12-05 | Donald A. MacLeod |
An automatic resetting subcircuit is disclosed in a remotely actuated power distribution switch control circuit characterized by a two-position electromechanical control for an automatic actuation mechanism for operating the switch. The control is provided with two elements, each for moving the control in an opposite direction between the open and closed positions of the switch. The circuit includes a first energy storage capacitor for storing energy received from a source remote from the circuit. A first thyristor, when triggered by a locally generated control signal, applies the energy stored in the first energy storage capacitor to one of the elements to cause the switch to be operated in a predetermined direction. The automatic resetting subcircuit includes a second energy storage capacitor for storing energy received from the remote source with the second energy storage capacitor being electrically isolated from the first thyristor. A sensor switch responds to the position of the distribution switch and is connected to reverse the connections of the first and second energy storage capacitors in accordance with the position of the power distribution switch. A time delay circuit is provided in conjunction with a second thyristor which is connected to the second energy storage capacitor and to the sensor switch. The gate of the thyristor is connected to the time delay circuit and to a transistor base controlled by the voltage on the first energy storage capacitor. If the voltage thereon goes to zero, indicating a signal switch, and the power distribution switch does not operate, the second thyristor passes the energy stored in the second energy storage capacitor to the other element of the electromechanical control to return the control to its initial position. |
