Method and apparatus for protection of wildlife from contact with power phase cutout mechanism
ActiveUS7154034B2Maintaining distance between parallel conductorsSuspension arrangements for electric cablesEngineeringHot stick
Method and apparatus for protecting wildlife from contact with an energized fuse assembly known as a “cutout”, also known as a “disconnect”. The cutout is shrouded from above and three sides. One side is left open to facilitate installation or removal of a fuse holder assembly. The shroud is formed to allow the use of a hot-stick for installation and removal of a fuse holder assembly into a fuse receptacle formed by upper and lower contact assemblies held in opposition to each other by an insulator. The shroud provides a slot enabling installation when a wire is connected to the upper contact assembly. A pin is used to hold the shrouding in place.

Fuse Cutout Monitoring and Indication Device
A device for monitoring and indicating a fuse tube detachment from a fuse cutout assembly contains a structural body, a tilt switch, a power source, a visual indicator, and an attachment mechanism. The attachment mechanism is used to mount the device onto the fuse tube. The tilt switch monitors the position of the fuse tube. More specifically, when the vertical position of the fuse tube changes to the dropped position the tilt switch is triggered. Thus, the visual indicator is illuminated. The illumination aids in the process of discovering the detached fuse tube. In addition to the visual indicator, the device can also be equipped with a wireless communication device and an alarm system. The wireless communication device can be used to provide the exact location of the detached fuse tube. On the other hand, the alarm system can be used to expedite the process of discovering the detached fuse tube.

Cutout box fuse bypass jumper
The fuse bypass jumper of the present invention bridges the upper and lower fuse terminals of a high-voltage transmission line cut-out box so as to bypass the fuse element. The jumper comprises lateral upper and lower arms connected by a longitudinal jumper bar. The jumper arms and bar are made of a heavy gauge conductor rated for at least 100 Amps. With the jumper in place, the fuse element can be opened, removed and / or replaced without interrupting the transmission line circuit through the cut-off box, since the jumper now provides a bypass around the fuse. Since the bypass conductive path constitutes a heavy gauge, high-amperage bar conductor, this jumper can carry a much larger current load than flexible wire-based jumpers.
