Movable Bearing Frame By-Pass Link for Power Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional by-pass systems for overhead power lines require a substantial amount of time and labor for installation, especially for high voltage lines, which can be critical during line failures or maintenance.
Innovation Solution
A by-pass link system comprising a housing with a movable bearing frame that supports an outdoor termination and electrical cable, allowing quick transition from a stand-by to an operating position, along with a prefabricated cable joint for plug-in connection, facilitating rapid installation and reducing the need for additional support structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional by-pass systems are used for overhead power lines, then the system can provide temporary power transmission during maintenance, but the installation requires substantial time and labor which is critical during line failures
Solution Approach 1:
The by-pass link is pre-assembled in a factory setting with all components (cable, terminations, support structures) prepared and integrated before delivery to the installation site. This preliminary assembly eliminates on-site assembly operations and significantly reduces installation time during critical maintenance windows
Solution Approach 2:
The by-pass system is divided into modular components that can be independently manufactured, tested, and transported. The standardized modules (cable sections, termination units, support structures) can be quickly assembled and configured at the installation site to match specific network requirements
2Device complexity
If conventional by-pass systems with separate components are used, then flexibility in configuration is maintained, but device complexity increases requiring multiple separate installations
Solution Approach 1:
Multiple by-pass link components (cable sections, terminations, support structures) are merged into a single integrated pre-assembled unit. This consolidation reduces the number of separate installation operations required and simplifies the overall installation process while maintaining the functional flexibility of individual components
3Reliability
If traditional termination installation methods are used, then proper electrical connection is achieved, but substantial labor and time are required for assembly and positioning
Solution Approach 1:
Electrical terminations are pre-assembled and pre-positioned on the by-pass link in the factory with precise alignment and secure mounting. This preliminary preparation ensures proper electrical connection quality while eliminating time-consuming on-site assembly and positioning operations
Solution Approach 2:
Traditional mechanical assembly methods for securing terminations are replaced with pre-assembled rigid mounting structures that provide stable electrical connections without requiring complex on-site mechanical assembly operations
