Universal Arrester Bracket Cap for Wildlife Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wildlife covers for arrester brackets on electrical transformers are not effective in preventing power interruptions caused by wildlife making contact with high voltage connections, as they do not adequately insulate the mounting points from ground potential.
Innovation Solution
A universal insulating cap designed to fit both standard-style and new-style arrester brackets, featuring a slotted portion for affixation to the bracket's rib and a cover portion that extends to partially cover the connecting bolt, providing enhanced insulation and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If small wildlife covers are used on arrester brackets, then the brackets are partially covered, but wildlife can still make contact with high voltage connections
Solution Approach 1:
The insulating cap is designed with a universal fit mechanism that accommodates both standard-style and new-style arrester brackets. The cap features an adjustable positioning system with movable clips that can secure to brackets of different dimensions, allowing a single cap design to perform the insulating function across multiple bracket types without requiring separate specialized caps for each style.
Solution Approach 2:
The invention extends the coverage area by adding a forward extension portion that projects beyond the rearward-facing surface of the bracket. This dimensional extension creates an additional insulating barrier in the forward direction, preventing wildlife from bridging between the bracket and high voltage connections from the front approach, thereby enhancing protection in a previously uncovered spatial dimension.
2Reliability
If insulating materials like tape or putty are used on mounting points, then insulation is provided, but they do not remain effective over the long term
Solution Approach 1:
The insulating cap is divided into distinct functional segments: a main body portion that provides the primary insulating barrier, forward extension portions that protect additional areas, and attachment mechanisms with movable clips. This segmentation allows each component to perform its specific function optimally while working together as an integrated system, with the rigid structured components maintaining their insulating properties over time without degradation.
Solution Approach 2:
The cap utilizes composite construction combining rigid insulating material for the main body with flexible attachment components. The rigid portions provide durable, long-term electrical insulation that does not degrade like organic materials (tape, putty), while the flexible clips enable proper installation and secure attachment, creating a composite structure that combines the advantages of both material types for sustained effectiveness.
3Adaptability or versatility
If a universal cap design is created to fit both standard-style and new-style brackets, then adaptability is improved, but device complexity increases
Solution Approach 1:
The attachment mechanism incorporates movable clips that can dynamically adjust their position and orientation to accommodate different bracket geometries. These clips are designed to flex and reposition during installation, allowing the same cap structure to securely attach to both standard-style and new-style brackets without requiring complex adjustable mechanisms or multiple specialized cap designs.

AI summary
A universal insulating cap for both standard-style and new-style arrester brackets is disclosed. The insulating cap has a slotted portion sized to receive a rib of an arrester bracket so that the cap may be affixed to the rib by sliding the cap over the rib. A cover portion of the cap extends forward from a slotted portion and is sized to at least partially cover a bolt or fastener that connects the arrester bracket to a mounting bracket affixed to a transformer tank. Projecting members extend from the inner walls of the cover portion and contact the sides of the standard-style arrester bracket to aid in holding the cap in place. The space between the projecting members is sized to receive a rib of the new-style arrester bracket to aid in holding the cap in place.
