Method and apparatus for protection of wildlife from contact with power phase cutout mechanism
View Patent ↗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.
1. A method for protecting wildlife from electrocution from an energized cutout assembly having upper and lower contact assemblies comprising:
shrouding an upper connector;
shrouding the upper contact assembly; and
shrouding a volume surrounding an upper-end of a fuse holder assembly wherein the fuse holder assembly includes an attachment means for a load breaking tool, and wherein all shrouding is accomplished using a one-piece shroud, wherein the shroud has a slot for accomplishing the shrouding and removing while an upper electrical wire is energized;
wherein the step of shrouding an upper connector comprises the steps of:
positioning a shroud over an upper conductor; and drawing the shroud over the upper end of the cutout assembly;
further comprising the step of disposing a pin through a first side of the shroud, the internal side of the upper contact assembly and a second side of the shroud to prevent unintended dislodging of the shroud.
2. The method of claim 1 further comprising the step of maintaining the dielectric integrity of an insulator supporting at least one of the upper connector and upper contact assembly.
3. The method of claim 2 wherein maintaining the dielectric integrity of the insulator comprises not bridging one or more skirts included in the insulator.
4. The method of claim 1 further comprising the step of providing an opening to the volume surrounding the upper-end of a fuse holder assembly, wherein said opening is for receiving the load breaking tool.
5. The method of claim 1 further comprising the steps of shrouding a portion of the upper electrical wire substantially from where the shroud for an upper connector is situated to a point along the electrical wire where wildlife can not come in contact with said electrical wire.
6. The method of claim 1 further comprising the steps of:
shrouding a lower connector;
shrouding a the lower contact assembly;
shrouding a volume surrounding a lower-end of a fuse holder assembly.
7. A cutout cover assembly comprising a single-piece upper cover that includes:
a first shroud section for shrouding an upper connector wherein the first shroud section comprises a conductor slot enabling installation of the cutout cover while the upper connector is attached to an upper electrical wire;
a second shroud section continuing from the first shroud section for shrouding an upper contact assembly;
a third shroud section continuing from the second shroud section for shrouding a volume surrounding an upper-end of a fuse holder assembly wherein the upper-end of the fuse holder assembly includes an attachment means for a load-breaking tool;
wherein the third shroud section comprises a top surface and two substantially opposing walls that continue to the end of a containment volume about the upper end of a fuse receptacle;
further comprising a tool inlet formed by sloping the two substantially opposing walls of the third section outward relative to the top surface; and
wherein the upper cover has the slot for accomplishing the shrouding and removing while the upper electrical wire is energized.
8. The cutout cover of claim 7 wherein the cutout includes an insulator and wherein the first shroud section, the second shroud section and the third shroud section, either collectively, individually or in any combination do not substantially compromise the dielectric integrity of the insulator.
9. The cutout cover of claim 7 wherein the cutout includes an insulator and wherein the first shroud section, the second shroud section and the third shroud section either collectively, individually or in any combination do not bridge one or more skirts included in the insulator.
10. The cutout cover of claim 7 wherein the first shroud section comprises either a multi-planar wall or a swept wall that surrounds a substantial portion of an insulator perimeter and a top surface.
11. The cutout cover of claim 7 wherein the second shroud section comprises two substantially opposing walls having upper edges wherein said walls straddle the upper contact assembly of a cutout and a top surface bridging the two walls at their upper edges.
12. The cutout cover of claim 7 further comprising two pin-holes disposed in opposing sides of the shroud and positioned below the height of an upper contact assembly.
13. The cutout cover of claim 7 further comprising a conductor shroud.
