Abstract
A connector for introducing fluid to an electrical cable affixed in a chamber internal to the connector, the connector comprising an injection port exposed to at least one exterior surface of the cable connector, wherein the injection port is in fluidic communication with the chamber, and a reticulated plug is positioned within an insulated segment of the injection port and sized to fill at least a portion thereof. The reticulated plug may be used in combination with various types of conventional injection connectors to allow swapping of an insulative permanent plug for an injection plug after a dielectric enhancement fluid has been introduced into the interior of a cable using the reticulated plug, wherein the cable is energized during the swapping operation.
Claims22
A cable connector configured for introducing a fluid to an electrical cable therein, the connector comprising:
- a connector body with an interior chamber sized for receiving and retaining therein a portion of the electrical cable, the connector body having an insulated portion;
- a fluid injection port comprising a fluid conduit extending between an exterior portion of the connector body and the interior chamber with at least a portion of the conduit passing through the insulated portion of the connector body, the conduit being configured for the flow of the fluid between the exterior of the connector body and the internal chamber;
- and
- a plug positioned within the portion of the conduit passing through the insulated portion of the connector body, the plug being porous and sized to fit within the conduit and to at least partially obstruct the conduit and increase the electrical resistance of the fluid path within the conduit extending between the exterior portion of the connector body and the interior chamber when the portion of the cable within the interior chamber is energized.
A high voltage electrical connector comprising:
- (a) an insulative body portion;
- (b) a conductive body portion external shield at least partially surrounding the insulative body portion;
- (c) a projection of electrically insulating material having a first end connected to the insulative body portion and a second end extending from the insulative body portion;
- (d) an injection port extending through the projection and having an opening in the second end of the projection in communication with an exterior of the electrical connector, the injection port communicating between the opening and a conductive insert of an interior of the electrical connector, the injection port having an insulated segment;
- and
- (e) a reticulated plug positioned within the insulated segment of the injection port so as to fill at least a portion thereof and to at least partially obstruct the injection port and increase the electrical resistance of a fluid path within the injection port when a portion of an energized cable is positioned within the conductive insert.
In a cable connector for introducing fluid to a cable, the cable connector having an injection port exposed to at least one exterior surface of the cable connector and a chamber internal to the cable connector adapted for affixing a cable internal to the chamber, wherein the injection port has an insulated segment, and the injection port and the chamber are configured to provide fluidic communication therebetween, the improvement comprising:
- a reticulated plug positioned within the insulated segment of the injection port and sized to fill at least a portion of thereof and to at least partially obstruct the injection port and increase the electrical resistance of a fluid path within the injection port extending between the chamber and the exterior surface of the cable connector when the cable in positioned within the chamber and energized.
