Swivel Coupling for High-Voltage Interrupter-Conductor Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling systems for conductor to interrupter connections in high voltage circuit breakers face challenges in maintaining consistent contact between the conductor and the circuit interrupter, leading to inefficiencies in electrical and mechanical attachment.
Innovation Solution
A coupling system that includes a connector with a receptacle and a swivel member, secured by a pin and fastener, which allows for secure axial and rotational alignment of the conductor rod to the interrupter, utilizing an electrical contact, such as a flexible bracelet, to ensure reliable electrical and mechanical linkage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If known clamping methods are used to attach the conductor to the circuit interrupter connection, then the attachment can be made, but the desired contact between the conductor and the circuit interrupter connection cannot be maintained
Solution Approach 1:
The coupling system incorporates a swivel member that allows dynamic adjustment and self-alignment of the conductor rod with the circuit interrupter connection. This dynamic mechanism ensures consistent contact by accommodating minor misalignments and movements, resolving the contradiction between maintaining reliable contact and avoiding overly complex fixed attachment structures.
Solution Approach 2:
The coupling system acts as an intermediary component between the conductor rod and the circuit interrupter connection. It includes a receptacle that receives the conductor rod end and a swivel member that mediates the connection, ensuring reliable electrical and mechanical contact while simplifying the overall attachment structure compared to direct clamping methods.
2Strength
If a secure connection is achieved between the conductor and interrupter, then electrical and mechanical stability is improved, but the complexity of the coupling system increases
Solution Approach 1:
The coupling system is segmented into distinct functional components: a receptacle for receiving the conductor rod end, a swivel member for alignment and connection, and a pin for securing. This segmentation allows each component to perform its specific function efficiently, achieving strong mechanical stability while keeping the overall system manageable in complexity through modular design.
