There is also a first plurality of conductors, each of which extends from the rear wall of the jack to adjacent a different one of said rear longitudinal contact terminal receiving slots.

Abstract: A high-voltage hybrid design switchgear with three power switch housings (1, 2, 3) arranged next to one another in series, each of which is connected to a horizontally arranged cylindrical adapter box (14, 15, 16). The adapter boxes (14, 15, 16) are arranged with their axes in parallel. Each adapter box has at least one high-voltage outdoor terminal (22, 23, 24) at a different distance from the series of power switch housings (1, 2, 3).

Abstract: A transformer station includes a plurality of power transmission lines receiving electric power, a bus bar connected to the power transmission lines, a transformer connected to the bus bar to transform voltage of the electric power supplied from the bus bar, and breakers between one of the power transmission lines and the bus bar and between the transformer and the bus bar. The breakers are aligned along an imaginary line extending substantially parallel to the bus bar.

Abstract: An isolator assembly (20) is provided for selectively isolating or connecting first and second bus bars (31) located on opposed sides of a wall (22). The assembly includes mounting means (24), for mounting the assembly (20) in the wall (22), and a through-wall conductor. The through-wall conductor (28) is supported by the mounting means (24) and has a contactor (30) capable of selectively making electrical contact with at least one of the bus bars (31). The conductor (28) is displaceable between a connecting position in which the conductor (28) connects the first and the second bus bars (31) and a disconnecting position in which the first and the second bus bars (31) are isolated from each other.

Abstract: Fuses for the potential transformers (PTs) in medium voltage switchgear are mounted in fuse assemblies which are reciprocated within the switchgear enclosure independently of the transformers they protect between a connected position in which the fuse assemblies engage stabs at the rear wall of the enclosure and a retracted position adjacent a door at the front of the enclosure through which the fuses are inserted and removed while the fuse assemblies remain within the enclosure. The fuse assemblies include insulative tubes having first releasable contacts at a distal end which engage the stabs and second releasable contacts which engage fixed contacts connected to the transformers and spaced from the rear wall. The insulative tubes are mounted on a carriage which reciprocates between the connected and retracted positions. An interlock prevents opening of the door except where the carriage is in the retracted position and blocks movement of the carriage with the door open.

Abstract: Disclosed is a power distribution substation for power distribution to a consumption pool having a high voltage unit divided into cells, each cell containing high voltage incoming connection equipments connected by high voltage cables to a power source having a voltage between 60 kV and 245 kV. The substation also has a transformers yard having at least one transformer connected to the high voltage incoming connection equipments, and a mid-voltage unit containing outgoing connection equipments connected to the transformer and linked to output power lines for power distribution under a voltage lower than or equal to 36 kV. Finally, the substation has a control room. The high voltage and mid-voltage units, the transformers yard and the control room are located in a single building having a roof where the high voltage incoming connection equipments, the transformer(s) and some of the outgoing connection equipments ate located at the same level inside the building.

Abstract: All power supplies and LAN adapters required for multiple computer terminals in a networked environment packaged within one portable enclosure that functions as a shipping case. The enclosure is used as an overhead projector table and a printer stand.

Abstract: An electrical energy-transforming equipment comprises a transformer arranged within a cubicle, a current transformer and a potential transformer both connected to the transformer. The transformer, the current transformer and the potential transformer are molded in one piece. In another form of the electrical energy-transforming equipment, a transformer for distributing electric power, which is molded with an insulating material, such as a synthetic resin or a synthetic rubber, is molded in one piece with a current transformer and a potential transformer both connected thereto, with an insulating material, such as a synthetic resin or a synthetic rubber. The electrical energy-transforming equipment may further comprise a breaker also molded in one piece with the rest thereof, with the insulating material.

Abstract: In a distributor, a plurality of switches are connected in series with one another on main distribution lines emerging from a receiver switching apparatus, thus forming a trunk. A branch line extends from a junction between each pair of adjoining switches and leads to each load via another switch and a transformer, wherein each pair of switches on the trunk is formed as a single branch unit, and the switch and transformer are united as a power package. In each power package, a supply bushing and a load bushing are placed on the top of a transformer, and shielded with closed housings. A switch is placed in the closed housing for the supply bushing, and a distribution board is placed in the closed housing for the transformer. This configuration enables the disconnection of any branch distribution lines from the main distribution lines and diminishes the installation space.

Abstract: A control unit forms a control center serving as one type of a control panel in an electric power system control system. The control unit accommodates equipments such as a circuit breaker, an electromagnetic switch, a zero-phase current transformer, and an operating transformer, and includes a substantially Z-shaped equipment mounting plate mounted between side plates of the unit to have an intermediate bent portion. The circuit breaker is disposed on a front face of a front mounting portion of the equipment mounting plate, and the current transformer is disposed on a back face thereof. The electromagnetic switch is disposed on a front face of a back mounting portion of the equipment mounting plate, and the thin operating transformer is isolated from other equipments and disposed on a back face thereof.

Abstract: An improved current mode coupler comprising a base (100), a housing (300) mountable to a panel. The coupler base (100) includes a pair of wire retainers (200) for securing the wires (230,231) of a twisted pair cable within wire receiving channels (204,205) of a wire nest (202) of the coupler base (100). Each wire retainer (200) has an arm (232), a strut (236) extending from one end thereof to a cylindrical hinge (234) disposed in a pivot region of the coupler base (100), a vertical section (240) proximate the other end including a latch (242), and a wedge (244) on the lower surface of the arm (232). Upon rotation of the wire retainer about hinge (234) to a closed position, wedge (244) is engageable with a lower one of the conductors (230) to urge it fully into a deeper one of the channels (204) adjacent a channel intersect ion proximate a conductor crossover.

Abstract: In a flyback transformer device wherein the leads of diodes or like electronic components are connected between pairs of terminal pieces provided upright at opposite ends of a coil bobbin, the lead ends of the components are fixedly connected to the respective terminal pieces by electric welding. A coil conductor wound around the bobbin has an end twined around the terminal piece, and the twined portion is soldered by dipping.
