Powerline Cutout Switch Vertical Extension and Mushroom Top
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power line cut-out switches lack a stable structure for securing mechanical jumpers, leading to potential electrocution or power interruptions when attaching or detaching solid jumpers, which are often made of thin copper and prone to breaking.
Innovation Solution
A power line cut-out switch with a vertical extension member and mushroom top member is used to securely attach the mechanical jumper, providing a more stable connection than traditional solid jumpers, allowing for uninterrupted power supply during post relocation or upgrading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical jumper is connected to solid jumper, then electrical connection is established, but connection stability deteriorates because solid jumper is made of thin copper and breaks when mechanical jumper is attached
Solution Approach 1:
The invention separates the attachment function from the electrical conduction function by introducing a distinct vertical extension member with mushroom top structure. This segmentation allows the solid jumper to focus on electrical conduction while the extension member provides structural support for mechanical jumper attachment, resolving the contradiction between connection stability and structural strength.
Solution Approach 2:
The vertical extension member with mushroom top acts as an intermediary element between the solid jumper and mechanical jumper. It transfers the mechanical load from the mechanical jumper to the base member, preventing direct stress on the thin copper solid jumper and eliminating the risk of breakage during attachment.
2Reliability
If clamp is used to attach solid jumper, then electrical connection is established, but reliability deteriorates when clamp is damaged causing power transmission interruption
Solution Approach 1:
The invention provides a backup attachment mechanism by securing the mechanical jumper to both the vertical extension member and the clamp. This redundant securing method ensures that if one attachment point fails, the other maintains electrical connection and power transmission, preventing complete power interruption.
3Ease of operation
If solid jumper is used for electrical connection, then electrical conductivity is achieved, but ease of operation deteriorates when post relocation is needed requiring complex procedures
Solution Approach 1:
The invention enables dynamic reconfigurability by allowing the mechanical jumper to be easily detached from the vertical extension member and reattached to a new location. This dynamic attachment mechanism simplifies post relocation operations, allowing workers to quickly move electrical connections without complex procedures or specialized tools.

AI summary
The present invention is a power line cut-out switch used in power transmission system comprising a base member having a vertical extension member perpendicularly attached thereon that secures a mechanical jumper used when transferring power lines from one electrical post to another. The vertical member can include a mushroom top member to further secure the mechanical jumper. The mechanical jumper is mounted to the vertical extension member to provide a stable and secure point of engagement when transferring power lines. This avoids electrocution to workers by no longer having to connect the mechanical jumper to flimsy solid jumpers and helps provide more uninterrupted power supply to consumers when installing new posts or shifting old posts to a new location.
