Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for maintaining and repairing high voltage transmission and distribution lines require de-energizing conductors, which is hazardous and disruptive, and there is a need for safe and efficient temporary suspension of conductors to allow hot line work without interruption.
Innovation Solution
A set of components including a yoke plate, J-hook assemblies, and linkage members, which can be assembled to create various configurations for temporarily suspending multiple conductors or sub-conductors, ensuring a safe pre-set clearance and secure support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductors are de-energized for maintenance and repair work, then safety is improved and work can be performed, but service interruption occurs and productivity is reduced
Solution Approach 1:
The patent applies preliminary action by providing temporary support structures (towers, poles, guys, cross-arms) in advance before conductor removal is needed. These pre-positioned structures enable immediate suspension of conductors when maintenance is required, eliminating the need to de-energize conductors and allowing continuous service while improving worker safety
2Productivity
If temporary support structures are installed to avoid de-energizing conductors, then service continuity is maintained and productivity is improved, but device complexity and installation time increase
Solution Approach 1:
The patent applies segmentation by dividing the temporary support system into modular, independent components: towers or poles, guys for lateral support, cross-arms for conductor attachment, and insulators. This modular segmentation simplifies installation and configuration, allowing structures to be assembled in standard sequences without excessive complexity while maintaining service continuity
3Device complexity
If multiple sub-conductors are suspended from the same insulator, then device complexity is reduced, but clearance and separation control become difficult
Solution Approach 1:
The patent applies dimensionality change by using cross-arms that extend horizontally from the vertical pole or tower structure. This creates a spatial separation in the horizontal dimension, allowing multiple sub-conductors to be suspended from different locations on the cross-arm while maintaining adequate clearance and separation, thus preserving manufacturing precision without increasing vertical device complexity

AI summary
A set of components for assembling a temporary wire suspender includes in the set a yoke plate, a plurality of J-hook assemblies, a plurality of linkage members, and a plurality of removable couplers configurable to handle an expandable number of energized or de-energized conductors or sub-conductors. Positive control of the suspended and/or supported energized or de-energized conductors or sub-conductors is achieved by using releasable latches on the J-hook assemblies.
