Abstract:
A jacket sleeve (300) with grippable tabs (306) provides protection to exposed portions of cable (26) 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 (300) 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 (300) can include holes or slots (310) 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.
Abstract:
A latching mechanism for joining separable insulated connectors employs a plurality of finger contacts (11) to create an interference fit with an electrode probe (1) of an elbow connector (21). The electrode probe enters a cylindrical grouping of the plurality of finger contacts and a projection (13) causes an interference fit between the finger contacts and' the electrode probe. The finger contacts latch the connectors (21, 31) together and require a removal force greater than the latching force required to latch the connectors. The latching mechanism provides a multi-point current path between an elbow connector and a power transmission or distribution apparatus and provides operator feedback to indicate the latching of the mechanism.
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:
A fusible disconnect device having auxiliary connections to line-side and load- side terminals and color coding features to indicate an amperage rating of a fuse.
Abstract:
A fusible switch disconnect device includes a housing adapted to receive at least one fuse therein, and switchable contacts for connecting the fuse to circuitry. A tripping mechanism is provided to disconnect the switchable contacts when predetermined circuit conditions occur.
Abstract:
A loadbreak connector system and methods for visible break include first and second mating connector assemblies configured to make or break an electrical connection under energized circuit conditions, the first and second mating connectors selectively postionable relative to one another. One of the first and second mating connectors includes an arc follower, and the other of the first and second mating connectors includes an arc interrupter. The arc interrupter is configured to receive the arc follower, and the first and second meting connectors are positionable in an disconnected position wherein the arc follower remains engaged to and is located within the arc interrupter. Arc energy is distributed among multiple locations to reduce arc intensity.
Abstract:
A separable loadbreak connector and system includes a connector having a contact tube with an axial passage therethrough, and a contact member slidably mounted within the axial passage and movable therein during a fault closure condition. The contact member is axially movable within the passage with the assistance of an arc quenching gas during the fault closure condition, and a shock absorbent stop element is mounted to the contact tube and limiting movement of the contact member in the fault closure condition.
Abstract:
In one embodiment, a system for coupling communications signals onto a medium- voltage power line includes a metal oxide varistor, a disconnect device and a capacitor. The metal oxide varistor is electrically coupled to the medium voltage power line. The disconnect device includes a resistor in parallel with an air gap and is electrically coupled in series between the metal oxide varistor and a communications device. The capacitor is electrically coupled to the metal oxide varistor and the communications device in parallel with the disconnect device.
