Bushing Accessory Support With Independent 3-Axis Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mounting systems for accessory equipment units, such as current transformer units, on bushing units with insulator parts are inflexible, making alignment and installation difficult, especially when multiple units are required, and can cause damage due to contact with bellows couplings during movement.
Innovation Solution
A modular support system with aligning means that allows separate alignment and adjustment of accessory equipment units in three directions (vertical, horizontal, and oblique) using adjustment slots and counter elements, integrated with the bushing to facilitate easy mounting, adjustment, and maintenance, preventing accidental contact with bellows couplings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dedicated supports are designed and constructed for each type of bushing and application, then the mounting precision and alignment of accessory equipment units is improved, but the device complexity and manufacturing time increase
Solution Approach 1:
The support structure is designed as a universal base that can accommodate multiple types of accessory equipment units (current transformers, voltage transformers, etc.) on different bushing configurations. The standardized mounting interface and adjustable positioning mechanisms allow the same support design to serve multiple applications, eliminating the need for dedicated supports for each bushing type.
Solution Approach 2:
The support structure is divided into modular components including a base plate, adjustable positioning elements, and separate mounting brackets. This segmentation allows for easy assembly, adjustment, and adaptation to different configurations without redesigning the entire support system, reducing manufacturing complexity while maintaining alignment precision.
2Stability of the object's composition
If accessory equipment units are fixed to the base of the bushing, then the mounting stability is improved, but the ease of operation for alignment and maintenance deteriorates
Solution Approach 1:
The support structure incorporates adjustable positioning mechanisms with movable components that allow alignment adjustments before final fixation. The design includes adjustable brackets and positioning elements that can be moved to different positions during installation, providing dynamic adaptability for precise alignment while ensuring stable fixed mounting once positioned.
3Adaptability or versatility
If multiple accessory equipment units are mounted on the base, then the functionality is improved, but the difficulty of detection and measurement of proper alignment increases
Solution Approach 1:
The support structure incorporates visual alignment indicators such as colored markings, alignment pins with visible indicators, or contrasting color schemes on the mounting surfaces. These visual cues make it easy to detect when accessory equipment units are properly aligned with the conductor and bushing, even when multiple units are installed, by providing clear visual feedback for correct positioning.
4Strength
If the support structure is integrated with the base of the bushing, then the structural strength is improved, but the ease of repair and replacement of accessory equipment units deteriorates
Solution Approach 1:
The support structure is designed as a separate modular component that interfaces with the bushing base through standardized connection elements. This segmentation allows the support and accessory equipment units to be removed as a module for maintenance or replacement without damaging or disassembling the bushing base itself, maintaining structural integrity while facilitating easy repair.
