Tangent Suspension Bracket for Transmission Line Rotational Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical transmission and distribution line repair devices lack sufficient mechanical support, particularly over tangent suspension insulators, which can lead to catastrophic damage due to vibrations, weather, corrosion, and other degrading conditions, necessitating additional support that maintains the same plane as the conductor to prevent rotational moments.
Innovation Solution
A tangent suspension bracket is designed to couple with suspension insulators and conductor clamp assemblies, featuring a central cap with attachment structures and tethers that secure the bracket to the insulator and conductor, providing additional mechanical integrity while maintaining alignment to prevent rotational moments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional mechanical support is provided to repair devices over tangent suspension insulators, then reliability and mechanical strength are improved, but device complexity increases
Solution Approach 1:
The bracket is divided into multiple functional components: a central cap for mounting to the insulator, end attachment structures for conductor connection, and side attachment structures for additional support. This segmentation allows each component to perform its specific function independently, improving overall reliability while keeping the design manageable.
Solution Approach 2:
The central cap serves multiple functions: it provides the mounting interface to the insulator, houses the attachment structures, and maintains the structural integrity of the entire bracket assembly. This multi-functionality reduces the need for separate components, thereby managing complexity while enhancing reliability.
2Stability of the object's composition
If the support structure is designed to remain in the same plane as the conductor, then rotational moments are prevented, but manufacturing precision requirements increase
Solution Approach 1:
The bracket employs asymmetric attachment structures positioned at specific locations on the central cap. The end attachment structures are positioned to align with the conductor axis, while side attachment structures provide lateral support. This asymmetric configuration inherently prevents rotational moments by creating a stable triangular support geometry that resists rotation without requiring extremely tight manufacturing tolerances.
Solution Approach 2:
The central cap is pre-configured with attachment structures positioned at predetermined locations that ensure proper alignment with the conductor. This preliminary positioning during manufacturing allows for easier field installation while maintaining the required planar alignment to prevent rotational moments.
3Strength
If multiple attachment structures are added to the bracket, then mechanical support is enhanced, but ease of installation decreases
Solution Approach 1:
Multiple attachment functions are merged into a single integrated bracket assembly. The central cap incorporates both end attachment structures for conductor connection and side attachment structures for additional support, all in one piece. This merging reduces the number of separate components that need to be handled and installed, thereby maintaining ease of installation while providing enhanced mechanical support through multiple attachment points.

AI summary
A tangent suspension bracket configured for coupling to at least one of a suspension insulator and a conductor clamp assembly. The tangent suspension bracket further includes a central cap, a first end attachment structure and a second end attachment structure. The central cap structure includes an upper wall having an opening and a depending skirt, together defining a downwardly opening cavity. The opening is structurally configured to allow the passage of a portion of one of the suspension insulator and the conductor clamp assembly while maintaining a portion within the downwardly opening cavity, so as to secure the central cap structure to one of the suspension insulator and the conductor clamp assembly. The first end attachment assembly extends from the central cap and the second end attachment structure extends from the central cap in the opposite direction.
