Surge Arrester With Universally Jointed Connecting Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surge arresters require a large physical space due to fixed-angle connections, which makes them difficult to handle and prone to mechanical damage from external forces, especially in severe weather conditions.
Innovation Solution
A universally jointed connecting path is used to decouple the surge arrester from the connecting terminals, allowing for a pendular movement and reducing the physical space required, while also providing mechanical decoupling to withstand external forces and environmental influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fixed-angle connections with lugs are used to connect the connecting path to the surge arrester, then the connection is mechanically stable, but the physical space required increases and handling becomes difficult
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed-angle rigid connections with a universally jointed bearing that allows dynamic movement. The connecting path can oscillate and adapt its position relative to the surge arrester, transforming the static connection into a dynamic one that reduces space requirements while maintaining mechanical stability through controlled movement capability.
2Device complexity
If fixed-angle connections with projecting lugs are used, then the connection structure is simple, but the arrangement becomes prone to mechanical damage from external forces
Solution Approach 1:
The universally jointed bearing introduces dynamic movement capability that allows the connecting path to absorb and dissipate external forces through oscillation. This dynamic response mechanism protects the surge arrester from mechanical damage caused by wind loads and other external forces, improving reliability without significantly complicating the connection structure.
3Ease of manufacture
If fixed-angle connections are used to complete the surge arrester before final assembly, then manufacturing is simplified, but the arrangement cannot withstand severe weather conditions
Solution Approach 1:
The universally jointed bearing enables the connecting path to move dynamically in response to weather conditions such as wind loads. This dynamic capability allows the surge arrester to be assembled earlier while maintaining weather resistance, as the joint can absorb and adapt to environmental forces rather than requiring rigid fixed-angle connections.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables a compact design that can withstand severe weather conditions and repeated load cycling, allowing for independent arrangement and movement of the surge arrester and connecting path, reducing mechanical stress and improving handling and durability.
Implementation Method 1
A universally jointed bearing for the connecting path makes it possible to arrange this in a pendular form. This avoids configurations in the connecting path occupying a physical space at a fixed angle.
