Detachable Insulator Support Assembly for Gas-Insulated Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for mounting and demounting insulators in gas-insulated transmission lines face issues such as welding spatters, complexity, and high costs due to mechanical wedge connections, which can damage structures during replacement or removal.
Innovation Solution
An insulation supporting assembly using detachable connections with threaded fasteners, comprising an insulator with supporting legs and connecting plates, allows for easy mounting and demounting by securing the insulator to the outer enclosure and inner conductor through threaded fasteners, enhancing stability and reducing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to mount the insulator to the outer enclosure and conductor, then the connection strength is improved, but welding spatters contaminate the insulator, conductor, and inner surface of the enclosure
Solution Approach 1:
The patent introduces connecting plates as intermediary components between the insulator and the outer enclosure/conductor. These connecting plates serve as mediators that provide mechanical attachment points without requiring direct welding to the insulator body, thus preventing welding spatter contamination while maintaining connection strength
Solution Approach 2:
The patent divides the mounting structure into separate components: the insulator body, supporting legs, and connecting plates. This segmentation allows the connecting plates to be positioned and secured separately from the insulator body, enabling attachment without welding to the insulator itself and thereby avoiding contamination
2Object-affected harmful factors
If mechanical wedge connection and necking process are used to mount the insulator, then welding spatter contamination is avoided, but the process is time-consuming and costly due to special jigs
Solution Approach 1:
The connecting plates are pre-formed with attachment features that enable direct bolting or clamping to the outer enclosure and conductor. This preliminary preparation of mounting interfaces eliminates the need for time-consuming on-site jig setup and complex mechanical wedge operations
Solution Approach 2:
The connecting plates serve as intermediary components that simplify the mounting process by providing standardized attachment interfaces. This intermediary structure replaces complex mechanical wedge connections and eliminates the need for special jigs, reducing both time and cost
3Object-affected harmful factors
If mechanical wedge connection and necking process are used to mount the insulator, then welding spatter contamination is avoided, but the connection structures are damaged when replacing or removing the insulator
Solution Approach 1:
The patent segments the mounting system into the insulator body and separate connecting plates. This segmentation allows the connecting plates to be detached and reattached without applying stress to the insulator body or the outer enclosure, preserving the integrity of these critical structures during insulator replacement
Solution Approach 2:
The connecting plates act as sacrificial intermediaries that can be easily removed and reinstalled without damaging the insulator or the outer enclosure. This intermediary layer protects the integrity of the main connection structures during maintenance operations
