[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application is a continuation-in-part of U.S. Nonprovisional Patent Application No. 17 / 933,997, filed September 21, 2022, and claims the benefit of and priority to U.S. Nonprovisional Patent Application No. 17 / 933,997, filed September 21, 2022, U.S. Provisional Patent Application No. 63 / 374,747, filed September 6, 2022, U.S. Provisional Patent Application No. 63 / 271,210, filed October 24, 2021, and U.S. Provisional Patent Application No. 63 / 246,783, filed September 21, 2021, all of which are incorporated by reference in their entireties herein.

[0002] BACKGROUND OF THEINVENTION This section is intended to introduce various aspects of the art that may be related to example embodiments of the present disclosure. The following discussion is believed to be helpful in providing a framework to facilitate a better understanding of certain aspects of the present disclosure. As such, it should be understood that this section is to be read in this light, and not necessarily as admissions of prior art.

[0003] The present concept relates to the field of power outage protection. In particular, the present invention relates to the prevention of power outages caused by wildlife and weather. [Background technology]

[0004] A common problem for electric power companies are outages that occur when a foreign object or animal comes into contact with an energized power line, bushing, or other component of an electrical system and becomes grounded, such as by contact with the top of a transformer. Once grounded, the energized object or animal can cause a short circuit and ultimately a power outage that can affect many homes and businesses. Such outages are associated with significant financial damages due to the temporary loss of power to end users, the labor costs involved in locating, determining the cause of, and restoring the outage, and the legal costs associated with lawsuits from disgruntled customers.

[0005] In addition to the economic damage, power outages caused by such animals can also result in animals dying after experiencing electrocution.

[0006] Current solutions don't adequately address the problem. For example, covering the bushings is not effective at preventing larger animals like cats, raccoons, possums, and bears, all of which are adept climbers and large enough to reach the tops of transformers and onto the wiring. If one of these animals touches the wiring and energizes it, it quickly creates a short circuit, which can lead to a power outage.

[0007] Alternative solutions offer no protection from the weather and are prone to damage or reduced electrical resistance when wet. Additionally, current solutions can easily become dislodged from their intended locations, resulting in frequent failure of protective devices and making them an ineffective solution to power outages. Current designs to address wildlife and weather-related outages are also inadequate for long-term use and often become brittle or damaged over time, requiring frequent replacement and maintenance.

[0008] Finally, current solutions are difficult or extremely dangerous to install on existing grids and require temporary grid shutdowns during installation, again causing consumer dissatisfaction and reduced revenue. Additionally, current solutions, if deployed in a timely manner, increase labor costs. As such, current insulation and wildlife deterrents are not viable and economical options for solving the focal problem of outages caused by short circuits caused by foreign objects and animals.

[0009] Therefore, there is a strong demand for a device that can effectively prevent power outages caused by animals or debris of any size, is weather resistant and durable, and can be easily and quickly installed without disconnecting the power source from the installation site.

[0029] Herein, one or more preferred embodiments are described in detail. However, it should be understood that the present invention can be embodied in various forms. Therefore, the specific details disclosed herein should not be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching those skilled in the art how to use the present invention in any suitable manner.

[0030] definition The singular forms "a" and "the" include the plural unless the context clearly dictates otherwise. The use of the term "a" in conjunction with the term "comprising" in the claims and / or specification may mean "one," but also means "one or more," "at least one," or "one or more."

[0031] Whenever words such as "for example," "such as," "including," and the like are used herein, they are understood to be followed by the phrase "without being limited to," unless expressly stated otherwise. Similarly, "examples," "exemplary," and the like are intended to be non-limiting.

[0032] The term "substantially" allows for deviations from the described words without adversely affecting the intended purpose. The described words are understood to be modified by the term "substantially" even if the word "substantially" is not explicitly mentioned. Thus, for example, the phrase "the lever extends vertically" means "the lever extends substantially vertically" unless a precisely vertical orientation is necessary for the lever to perform its function.

[0033] Terms such as "comprising," "including," "having," and "involving" (as well as "comprising," "including," "having," "involving") are used interchangeably and have the same meaning. Specifically, each term is defined consistent with the general U.S. patent law definition of "comprising," and is therefore to be interpreted as an open-ended term meaning "at least the following," and not excluding additional features, limitations, etc. Thus, for example, "a process comprising steps a, b, and c" means that the process includes at least steps a, bc. Whenever the term "a" is used, it is understood to mean "one or more," unless such an interpretation is insignificant in the context.

[0034] As used herein, "about" means roughly, in the region of, roughly, or in the region of. When the term "about" is used in conjunction with a numerical range, it modifies that range by expanding the boundaries above and below the numerical values ​​set forth. In this context, "about" generally means to modify numerical values ​​above and below the set forth value by 20 percent (higher or lower).

[0035] For purposes of this disclosure, spatially relative terms such as "top", "bottom", "right", "left", "lower", "below", "lower side", "upper", and the like may be used for ease of description to describe the relationship of an element or feature to another element or features as shown in the various figures. However, it should be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the figures. For example, if the device in the figures is flipped or rotated, an element described as "below" or "below" another element or feature will be oriented "above" the other element or feature. Thus, the exemplary term "below" may encompass both a top and a bottom orientation. The device may be in other orientations (90 degrees or other orientations) and the spatially relative descriptors used herein should be interpreted accordingly.

[0036] As used herein, "transformer" may refer to a commercially available transformer or a custom manufactured transformer. For example, transformers may include step-up transformers, step-down transformers, power transformers, distribution transformers, potential transformers including current transformers and potential transformers, single-phase transformers, three-phase transformers, autotransformers, or any combination thereof. Transformers include transformers useful in overhead transmission systems, underground transmission systems, or combinations thereof.

[0037] As used herein, "non-conductive material" may refer to a material that blocks or reduces the flow of electrons from one surface to another. Non-limiting examples of non-conductive materials may include rubber, plastic, paper, glass, porcelain, ceramic, or any other material now known or later developed that is effective in impeding the flow of electrons.

[0038] As used herein, "animal" may refer to any living organism large enough to short out an electrical power supply system. "Animals" may include mammals, reptiles, birds, or combinations thereof.

[0039] "Debris" as used herein may include any inanimate foreign object large enough to short out an electrical power supply system. Examples of debris include kites, drones, toy helicopters, balls, balloons, or other objects that may accidentally come into contact with a transformer. "Debris" may also include any object that is intentionally directed to disrupt electrical power supply, such as a crime or terrorist attack. "Debris" may further include debris that may come into contact with electrical power lines during or immediately after a natural disaster, such as a hurricane, tornado, or other natural disaster. "Neat fit" as used herein refers to an opening that fits snugly into another feature, such that debris cannot enter between the opening and the feature, but may allow for a tolerance between the opening and the feature.

[0040] Description of Selected Specific Embodiments Provided herein is an apparatus configured to prevent power outages. In various exemplary embodiments, the apparatus includes an insulator configured to prevent electrically charged animals or debris from contacting a ground plane of a transformer.

[0041] FIG. 1 shows a typical three-phase overhead power transmission system with a power interruption protection insulator 100 according to an embodiment of the present invention. In this figure, a transformer 510 is seen supported on a utility pole with two bushings 520 extending upward from the top of the transformer. One bushing and the transformer are shown connected to the B phase and primary neutral conductors of the power system, respectively, such that the system is energized and the transformer serves as the potential ground for the energized system. As shown in FIG. 1, the insulator 100 covers the entire top surface of the transformer 510, thereby forming an effective barrier to prevent a short circuit event from occurring if an animal or debris becomes energized, such as by contact with cables or other energized conductors that are part of the power transmission system.

[0042] FIG. 2A shows a standard three-phase overhead power transmission system with a power interruption protection insulator 100 according to another embodiment of the present invention. In this figure, a transformer 510 is supported on a utility pole, and two bushings 520 can be seen extending upward from the top of the transformer. One bushing and the transformer are shown connected to the B phase and primary neutral of the power system, respectively, so that the system is energized and the transformer serves as the potential ground for the energized system. As shown in FIG. 1, the insulator 100 covers the entire top surface of the transformer 510, thereby forming an effective barrier to prevent a short circuit event from occurring if an animal or debris becomes energized, such as by contact with a cable or other energized conductor that is part of the power transmission system. The embodiment of FIG. 2A further includes an enclosure 150 that surrounds the bushings 520 to further prevent contact with animals and debris. In this embodiment, the housing 150 includes a top surface and side walls that extend downwardly therefrom and connect to the insulator 100 without significant gaps or openings, further protecting the power distribution system from short circuit events.

[0043] 2B shows a top view of one embodiment of the invention installed on a transformer. Note that in this view, the view of the transformer is obstructed by the insulator 100, which is shown resting on the top surface of the transformer. Here, the entire top surface of the insulator 100 is visible below a grid, cage, or guard 151 that forms the top surface of the housing 150. Two bushings 520 are also visible below the grid, cage, or guard 151. In this embodiment, the grid, cage, or guard 151 comprises a grid-like structure that allows an electrical cable to contact the bushings 520.

[0044] 2 may be reversibly attached to the insulator 100 or may be integral with the insulator 100. In an embodiment, the housing 150 is snapped or screwed into place around the bushing and bonded to the insulator 100.

[0045] FIG. 3A is a top view of the top surface 201 of an insulator 200 according to one embodiment of the invention. The illustrated insulator 200 includes a bushing port 225 extending therethrough in the form of a hole, gap, notch, channel, or combination thereof. The insulator of the embodiment of FIG. 3 further includes a connector assembly 207 that allows the insulator to be easily installed and secured to the top surface of a transformer. In this embodiment, the connector assembly 207 includes overlapping flaps, a top flap 209 and a bottom flap (shown at 211 in FIG. 3B), that function to help form a continuous barrier to prevent contact with the top surface of the transformer from energized animals and debris.

[0046] 3B is a bottom view showing the bottom surface 203 of the insulator 200. In this embodiment, the insulator 200 includes a sidewall 205 that extends downward from the top surface of the insulator 200. In operation, the sidewall 205 can function to prevent at least a portion of the transformer side from contacting an energized animal (such as via a dangling tail or feet that may contact the side of the transformer). In an embodiment, the sidewall 205 can extend up to about 1 / 10 of the length of the transformer side. The sidewall 205 can extend up the entire side of the transformer. In a particular embodiment, the sidewall 205 extends up to about half of the side of the transformer. The side wall 205 may extend over about 1 / 16, about 1 / 8, about 3 / 16, about 1 / 4, about 5 / 16, about 3 / 8, about 7 / 16, about 1 / 2, about 9 / 16, about 5 / 8, about 11 / 16, about 3 / 4, about 13 / 16, or about 7 / 16 of the side of the transformer. It can be configured to extend up to 8.

[0047] 3B, the connector assembly 207 may further include a means 210 for reversibly securing the insulator 200 to the transformer. As shown, the means for reversibly securing the insulator to the transformer may include a hook-and-loop strap 210. In alternative embodiments, the means for reversibly securing the insulator 200 to the transformer 210 may include a latch, buckle, clamp, clasp, side release buckle, carabiner, snap fit, friction fit, hook, button and eye, cam lock, post and keyhole, press fit, screw lock, snap, spring loaded pin, other attachment means known in the art, or combinations thereof.

[0048] In this embodiment, the means for reversibly fastening the insulator 210 is seen at the end of the bottom flap 211 of the connector assembly 207. However, the means for reversibly fastening the insulator 210 to the transformer may be located anywhere on the insulator 200. In an embodiment, the means for attaching the insulator 200 to the transformer may be located on the insulator, on the transformer, or both. As an example, the transformer may have male snaps and the insulator may have female snaps, or vice versa, to allow for alignment of the snaps to effectively couple the insulator to the transformer. Alternative attachment means as disclosed herein may be applied in a similar manner.

[0049] In various embodiments, the insulator and the transformer can be quickly coupled by the connector assembly 207. The connector assembly 207 can be configured to allow installation of the insulator 200 in an energized system. For example, the insulator 200 can be safely installed by a lineman without requiring a temporary shutdown of the electrical system or other period of power outage. Embodiments are configured to allow installation of the insulator 200 in less than five minutes. In embodiments, the insulator 200 can be installed in less than one minute. In embodiments, the connector assembly 207 allows installation of the insulator 200 without the need for tools.

[0050] FIG. 3C shows a side perspective view of the insulator 200 according to the embodiment of FIG. 3A, and FIG. 3D shows a side view thereof. These views show the sidewall 205 of the insulator 200. Additionally, it can be seen that the top surface 201 of the insulator 200 can have an angled or shaped configuration. Alternative configurations are also included in the present disclosure. As an example, the insulator can be configured to be compatible for use with any of a variety of transformers currently on the market or later developed that allow the insulator 200 to provide a tight, continuous seal around the top of the transformer. Additionally, the insulator 200 can be configured to provide a tight, continuous seal around the sides of the transformer.

[0051] Although the shape of the insulator 200 in FIG. 3 is generally conical or circular, in alternative embodiments, the insulator 200 has any shape. In embodiments, the shape may be elliptical, circular, or polygonal. In certain embodiments, the shape of the insulator 200 may include a rhombus, a parallelogram, or a trapezoid. The shape of the insulator 200 may also include a triangle, a square, a rectangle, a pentagon, a hexagon, a heptagon, an octagon, a nonagon, a decagon, a circle, an ellipse, a semicircle, or a quadrant. In certain embodiments, the insulator has a shape that includes one or more arcs, parabolas, or hyperbolas.

[0052] 4A-4E, insulator 300 is made up of two pieces, a left portion 320 and a right portion 340, which are assembled on top of transformer 510 to protect transformer 510. Similar to insulator 100, insulator 300 has a bushing port 325, a sidewall 305, a top surface 301, and a bottom surface 303.

[0053] Optional rotatable pin hinge left and right portions 318, 319 allow the insulator 300 to pivot open and close from one end, and optional fasteners 313 (male 314 and female 316) on the other end. Each side has optional flanges 312 with optional slots 312 useful for fastening the left and right portions together, or that the lineman can use to attach other objects. Cable ties, other connectors, or fasteners can be used through these slots 312. The slots 312 are shown rectangular in shape, but could be circular, square, hexagonal, octagonal, or any other shape. Additionally or alternatively, the insulator 300 can be optionally secured by means 210.

[0054] In addition to or instead of the flange 310 with slot 312 described above, a clip 360 may be used, as shown in another exemplary embodiment of an insulator 350 in FIGS. 6A and 6B.

[0055] This embodiment has an optional transformer spacer 344 that can be placed directly on top of the transformer. This spacer is useful for creating an insulating gap between the top of the transformer and the bottom of the insulator. This allows for a thinner material for the insulator. Additionally, the spacer can be laid flat on a surface, allowing the insulator to stay in place if it encounters animals or inclement weather. Additionally, the spacer can provide structural strength to the insulator.

[0056] This embodiment also has an optional undercut lip 342 extending from the sidewall 305 that can help minimize potential gaps between the insulator 300 and the transformer 510 to prevent objects from entering through the gap. As used herein, "undercut" refers to a shape (e.g., rock with a bottom eroded by a river) and not a manufacturing process step. Additionally, the sidewall and undercut lip of the insulator can help secure the insulator to accommodate the upper lip 515 of the transformer.

[0057] The exemplary bushing port 325 of the insulators 300, 350 is sized with a clearance to the inner diameter of the ceramic insulator of the bushing, while the exemplary bushing port 425 is sized with a clearance to the outer diameter of the ceramic insulator of the bushing. A smaller size is better at preventing debris ingress, but a larger size allows more flexibility in the location of the insulator relative to the bushing. Any of these sizes or others may be employed. Optionally, an insulating sealant may be used to prevent debris from ingressing through the bushing port into the transformer area.

[0058] Another exemplary embodiment is insulator 350, FIG. 6A-6B, which is similar to insulator 300, except that instead of flange 310 on top surface 301 of insulator 300, insulator 350 has an optional clip or clips 360 that can be used to secure the left and right portions together. FIG. 6A shows the left and right portions of insulator 350 assembled, held together by clip 360 and fastener 313. Clip 360 can reversibly secure the left and right portions together using surface friction, a recess that captures the clip, a detent, or other methods. Alternatively, it can be substituted for connector assembly 207 of insulator 200.

[0059] 7A-7C show another example insulator 400 with flat top surface 401 and flat bottom surface 403. As shown in FIGS. 7A-7C, the flange 310 of this example insulator 400 may optionally extend the length of the insulator 400 from the undercut lip 342 onto the top surface 401 (or bottom surface 403) until it again reaches the undercut lip 320. The insulator 400 includes a differently shaped transformer top spacer 344.
