  • Patent number: 8378219
    Abstract: A bus assembly and bus assembly connector include one or more insulated members that have axial sleeves that fit within one another during assembly to form a nesting arrangement. The nesting arrangement of the axial sleeves allow reduction of the overall size of the bus assembly connector while satisfying power rating standards and dielectric clearances as well as allowing bolting of the bus assembly to thereby clamp and secure the bus assembly. The axial sleeves can be distinctively designed such that the phase members must be assembled in a predetermined order, with no components being omitted, to form the bus assembly connector or clamp the bus assembly.

  • Patent number: 7591660
    Abstract: The present invention is directed to an apparatus and method for connecting a unitary cable terminal plate assembly to a busbar from multiple directions in tight closed spaces so that space and assembly problems are improved. A lug connection is accomplished by combining a polyhedron nut having differently oriented nut holes for cooperation with bi-directional holes in the terminal plate assembly together with a stair-step frame to orient the nut in the terminal plate assembly. This bi-directional connection made with a nut, terminal plate, and frame ensures that no change has to be made to a vehicle component needing an electrical lug connection. Further this invention allows for a preferred tool drive direction, for example only vertically, even though the unitary assembly is being repositioned for better packaging orientation.

  • Patent number: 7367830
    Abstract: A busway fitting wherein the switch and/or fuse are disposed in a horizontal orientation. As the switch assembly and/or fuse are disposed in a horizontal orientation, the buses coupled to the switch assembly and/or fuse also extend horizontally. As such, the buses coupled to the switch assembly and/or fuse occupy a reduced amount of space. In this configuration, the transition buses may extend in a generally horizontal direction and, as such, the size of the busway fitting may be reduced.

  • Patent number: 7336083
    Abstract: A connecting sleeve generally used for a bus bar connection is produced from an insulating elastic material, often an elastomer material, having insulating properties which are deteriorated by partial discharges and decrease over the operating time of the switchboard system. According to the invention, so-called partial discharge measuring methods must be carried out, inter alia also in the UHF range (UHF: ultra high frequency), in order to identify damaging effects on the insulating material in time. For the reliable and simple detection of the measuring signals, the connecting sleeve (M) has an outer, electroconductive surface (OA) which is earthed, and an inner, electroconductive surface (OI) to which the voltage potential of the bus bar (S) is applied, in addition to a coupling electrode (KE) which is integrated into the insulating material (I).

  • Patent number: 7335041
    Abstract: A bus bar support, including a lower part which can be mounted with a lower side thereof to the base. Several bus bars which are disposed in a longitudinal direction and at a distance from each other, are used to insert, in an isolated manner, bush bars extending in a transversal direction and are arranged in an upper side of the lower side. The bush bar support also includes a removable upper part which blocks and closes the bus bars. One object of this invention is to provide bus bars in a simple manner, which are easy to handle and which can adapt in many ways to the bus bars which have various cross sections. As a result, the bus bar support includes separate sliding elements which are used to define the bus bar receiving elements in a direction of thickness extending from the lower side to the upper side. Bearing inserts are used to define the bus bar receiving elements in a direction of width extending in a transverse manner on the longitudinal extension of the inserted bus bars.

  • Publication number: 20080038949
    Abstract: A maintenance-free electrical bus assembly is provided for a switchgear cabinet. The maintenance-free electrical bus assembly is coupled to a switchgear device in the cabinet, and includes electrical bus members, at least one bus joint comprising an electrical connection of two or more electrical bus members, and a fastener assembly fastening the bus joint and maintaining the electrical connection between the electrical bus members thereof. The fastener assembly includes at least one first fastening element having a plurality of first threads, and at least one second fastening element having a plurality of second threads. The second threads threadably engage the first threads of a corresponding first fastening element, in order to perpetually secure the first threads and the corresponding first fastening element, and to resist undesirable loosening of the bus joint once the fastener assembly has been fastened. Thus, inaccessible bus joints within the cabinet do not need to be inspected.

  • Patent number: 7297009
    Abstract: A kit includes a trim plate that has rigid sections arranged end-to-end, defining a cavity within an inner perimeter thereof. Each section has a corresponding beveled edge outwardly sloping away from the inner perimeter. A core member has a unitary body formed from deformably resilient material and is registered between the rigid sections, beneath the floor surface. Mounting flanges are aligned along the inner perimeter of the trim plate and abuts the outer perimeter of the core member. Each mounting flange has ribs that inwardly protrude into the core member and extend along an entire length thereof. The ribs are coupled with the core member so that same is prohibited from downwardly traveling beneath the floor surface. Computer cables pass through the core member, causing same to expand against the mounting flanges and constrict air gaps created within the core member when the cables are passed below the floor surface.
