Solution Overview
Problem
Existing split core current sensing transformers face difficulties in aligning core portions during reassembly in crowded or confined spaces, particularly when installed in enclosures with limited room, making it challenging to efficiently utilize available space and avoid obstacles.
Innovation Solution
The design incorporates separable and rotatable core portions with a guide pin and socket system, allowing relative translation and rotation about an offset axis, facilitating self-alignment and easy assembly in tight spaces, and utilizing the available space effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hinged split core transformer is used to facilitate installation without disconnecting the conductor, then ease of operation is improved, but device complexity increases and alignment difficulty arises in crowded spaces
Solution Approach 1:
The transformer core is divided into separable portions that can be independently handled during installation. Each portion can be maneuvered separately through crowded spaces and then joined together to form the complete encircling structure around the conductor.
Solution Approach 2:
A guide pin mechanism serves as an intermediary component that facilitates the alignment and joining of core portions. The guide pin inserts into a guide pin socket to provide mechanical guidance and ensure proper positioning of the separable core portions relative to each other.
2Volume of moving object
If separable core portions are used to reduce assembly space requirements, then volume is reduced, but alignment precision deteriorates in confined spaces
Solution Approach 1:
The guide pin and guide pin socket act as intermediary alignment features that bridge the separable core portions. During assembly, the guide pin插入the guide pin socket to provide mechanical guidance, ensuring that the core portions align precisely even when assembled in confined spaces with limited maneuverability.
Solution Approach 2:
The guide pin mechanism provides self-aligning functionality during assembly. As the core portions are brought together, the guide pin automatically guides them into the correct relative position through the guide pin socket, eliminating the need for external alignment tools or complex adjustment procedures.
