Fault-locating Apparatus with Guides for Overhead Power Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for locating faults in overhead power transmission lines require special equipment, such as cranes, to install fault-locating apparatuses on lightning-protector cables or power conductors, especially when the cable direction varies, limiting their applicability.
Innovation Solution
The apparatus incorporates guides attached to its case that can set the trajectory of the lightning-protector cable or power conductor, allowing the apparatus to be installed without additional special equipment, using a drive system with two traveling rollers and a clamping roller to secure and move along the cable, and a helicopter-type aircraft for positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If special equipment such as cranes is used to install fault-locating apparatuses on lightning-protector cables, then the installation can be performed, but the complexity of the system increases and the applicability is limited
Solution Approach 1:
The patent extracts and eliminates the need for external special equipment (cranes) by integrating all necessary installation functions into the fault-locating apparatus itself. The self-contained design includes its own positioning, attachment, and movement mechanisms, allowing it to be deployed without external assistance.
Solution Approach 2:
The fault-locating apparatus is designed to be self-sufficient, performing its own installation and positioning operations. It autonomously attaches to the lightning-protector cable, positions itself using onboard sensors and guidance systems, and moves along the cable without requiring external cranes or specialized installation equipment.
2Adaptability or versatility
If the fault-locating apparatus is designed to work on cables with varying directions, then the adaptability increases, but the device complexity increases
Solution Approach 1:
The apparatus incorporates dynamic adjustment mechanisms that allow it to adapt to varying cable directions in real-time. The structure includes movable and adjustable components that can change orientation and configuration to match the cable's path, enabling operation on cables with angles up to 45 degrees without requiring multiple specialized devices.
Solution Approach 2:
The fault-locating apparatus is designed as a universal device capable of operating on lightning-protector cables regardless of their direction or configuration. It integrates multiple functions including positioning, attachment, fault detection, and navigation into a single multi-functional system, eliminating the need for direction-specific variants.
3Ease of operation
If additional special equipment is used for installation, then the installation capability is improved, but the loss of time and resources increases
Solution Approach 1:
The apparatus is pre-configured with all necessary components for installation and operation. The guidance systems, attachment mechanisms, and positioning devices are pre-installed and calibrated, allowing for rapid deployment directly onto the cable without requiring sequential installation of multiple separate equipment pieces.
