Abstract:
An electrical connector includes a sleeve defining an axis and a contact assembly inserted in the sleeve, the contact assembly including pieces that move axially relative to one another during a fault close operation. An interface between the sleeve and the contact assembly is configured to permit replacement of the contact assembly without replacing the sleeve.
Abstract:
A seal is provided around a vacuum interrupter and an air-filled cavity, and a tube is provided within the seal. The tube has a first end open to the air-filled cavity and a second end open to an exterior of the seal. The seal, the vacuum interrupter, and the air-filled cavity are encapsulated.
Abstract:
An electrical panel assembly comprised of individual electrical panel modules. The electrical panel modules comprise a first receptacle comprising transmitting electrical contacts to interface with a first connector comprising receiving electrical contacts and a first rotation ring for facilitating contact between the transmitting electrical contacts and the receiving electrical contacts, where the first rotation ring rotates between an open position permitting connection or disconnection of the first connector from the receptacle and a closed position preventing connection or disconnection of the first connector from the first receptacle. The first electrical panel module interacts with a second electrical panel module in a manner that the absence of the first connector in the first receptacle prevents the second electrical panel module from accepting a second connector.
Abstract:
The present invention provides for a linear lighting apparatus. The apparatus includes a plurality of light emitting diodes, a primary optical assembly, and a secondary optical assembly. The light emitting diodes produce light towards the primary optical assembly. The primary optical assembly refracts this light towards the secondary optical assembly. The secondary optical assembly receives this light and refracts the light again so that the light emanates from the linear lighting apparatus. The present invention also provides a method for improving lighting efficiency from a linear lighting apparatus. The method includes emitting light from a plurality of light emitting diodes, refracting the light in a primary optical assembly, receiving this light refracted by the primary optical assembly, and refracting this light in a secondary optical assembly so as to direct the light from the apparatus.
Abstract:
A light source is combined with an optic and a reflector. Light incident onto to the reflector is reflected with a single reflection. The reflector occupies a portion of a solid angle around the light source to the exclusion of the optic at least with respect to any optical function. The reflector directly receives a second portion of light. The optic occupies substantially all of the remaining portion of the predetermined solid angle to directly receive a first portion of light from the light source. A reflected beam from the reflector is reflected into a predetermined reflection pattern. The inner and/or outer surface of the optic is shaped to refract or direct light which is directly transmitted into the optic from the light source from a first portion of light and/or reflected into the optic from the reflector from the reflected beam into a predetermined beam.
Abstract:
The power box can be stacked while limiting horizontal translation. The power box includes an electrical component box, a cover for the electrical component box, and a support assembly. The support assembly has feet that raise the electrical component box off of the ground. The cover includes one or more raised projections that restrict the horizontal translation of a power box positioned thereon, by dimensioning the projections apart by a distance slightly greater than an exterior width of the support assembly of the power box that rests upon the cover. Horizontal translation is further limited by dimensioning the feet such that, when placed on top of another power box, the interior dimension between two feet is slighting greater than the dimension of the cover. So, when the top power box attempts to slide, the feet of the top power box contact the cover of the bottom power box.
Abstract:
A fuse comprising a fuse body having ferrules at opposing ends, a fuse state indicator located on the surface of the fuse body wherein the fuse state indicator may be temperature sensitive or voltage sensitive and a wire extending from one ferrule to the other ferrule wherein the wire is positioned along the surface of the fuse body. The fuse state indicator senses heat generated by the wire or voltage flowing through the wire.
Abstract:
Separable loadbreak connectors include an interference element spaced about the contact tube that is configured to engage a portion of a connector piston.
Abstract:
Indicator devices and systems are provided. Indicator devices include a sleeve, a dome-like transparent member, a connector body, and an indicator. In alternate embodiments, indicator devices include a sleeve and an indicator retained in the sleeve by a retaining ring and a latch held in place by a spring. Indicator systems include an indicator device coupled to an enclosure containing critical equipment.
Abstract:
A jacket sleeve with grippable tabs provides protection to exposed portions of cable that are connected to an electrical connection. The jacket sleeve can be made as part of the electrical connector or may be connected subsequent to its creation through the use of glues or other adhesives. The jacket sleeve can be made of a material that is more pliable than the electrical connector, making it easier for a lineperson to place the sleeve over an exposed portion of cable. The jacket sleeve can include holes or slots either in the sleeve or in tabs that are attached to the sleeve. A lineperson can place one or more fingers into each hole or slot in order to get a better grip on the sleeve and pull the sleeve over the exposed portion of cable with less slippage and effort on the part of the lineperson.
