Overhead Line Grounding Device with Electronic Key Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for grounding overhead electrical lines are inadequate as they require multiple devices for each conductor, are unusable if the removable key is lost, and cannot efficiently control multiple clamps and vices simultaneously.
Innovation Solution
A device with communication means between control and locking mechanisms, allowing electronic key-like control over multiple vices and clamps, enabling efficient grounding of multiple conductors and easy reprogramming of lost keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single removable key is used to control multiple vices and clamps, then device complexity is reduced, but reliability deteriorates because the system becomes completely unusable if the key is lost
Solution Approach 1:
The patent divides the control system into multiple independent electronic keys, each capable of controlling specific vices and clamps individually. This segmentation means that if one electronic key is lost, the system can continue to function using other keys, thereby maintaining reliability while still reducing overall device complexity compared to having separate mechanical keys for each component.
2Reliability
If multiple separate grounding devices are provided for each conductor, then reliability is improved, but device complexity and quantity increase
Solution Approach 1:
The patent combines multiple vices and clamps into a single integrated grounding device that can simultaneously ground multiple conductors. The device includes multiple vices (2, 3) and clamps (4, 5, 6, 7) that can be controlled by a single electronic key, reducing the total number of separate grounding devices needed while maintaining reliable grounding assurance for each conductor through the unified control system.
3Ease of operation
If communication means are added between control and locking mechanisms, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical key-control systems with an electronic communication-based system. Electronic keys transmit control signals wirelessly or through electrical connections to the locking mechanisms of vices and clamps, eliminating the need for physical key insertion and manipulation. This substitution significantly improves ease of operation while the modular communication architecture helps manage the added complexity.
