Phase Ring Assembly Recessed Connection Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing phase ring assemblies in electric generators are space-constrained due to the occupation of connection arms and their brackets around the support ring, limiting space for other components and causing reduced stiffness and increased heating losses.
Innovation Solution
A phase ring assembly design where connection arms are placed between the phase rings and the support ring, with recessed seats in the support ring to house the connection arms, allowing for increased support ring thickness, reduced vibrations, and protection from circulating gas, using spacers and bars for additional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection arms are placed above the phase rings with clamping brackets, then the connection arms are securely supported, but the space around the support ring is occupied and space for other components is reduced
Solution Approach 1:
The connection arms are nested within recesses formed in the support ring, placing them inside the radial space of the support ring rather than above the phase rings. This nesting arrangement secures the connection arms while freeing up the external space around the support ring for other components.
Solution Approach 2:
The connection arms are repositioned from a vertical arrangement (above the phase rings) to a radial arrangement (within the support ring). This dimensional change moves the connection arms into the radial thickness of the support ring, optimizing space utilization in the vertical direction.
2Stability of the object's composition
If support ring thickness is increased to enhance stiffness, then vibrations are reduced, but the space for other components is further reduced
Solution Approach 1:
The connection arms are relocated to the radial dimension (within the support ring thickness) rather than occupying vertical space. This allows the support ring to be thickened for stiffness without proportionally reducing the vertical space available for other components.
3Temperature
If connection arms are exposed to circulating gas, then cooling is provided, but heating losses increase
Solution Approach 1:
The connection arms are extracted from the circulating gas environment by placing them within the recesses of the support ring. This isolation protects them from direct gas exposure, reducing heating losses while the support ring structure provides alternative thermal management.
