Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration reduction systems for transformers are limited in their ability to effectively reduce vibration and noise across various transformer sizes and configurations, often requiring redesigns and are not suitable for transformers not buried in the ground, and struggle to address vibrations radiated in different directions.
Innovation Solution
A vibration reduction unit comprising a first frame, a second frame with a resonance space, and a pipe member that communicates with the outside, allowing for the reduction of vibrations through resonance, with adjustable design features such as through-holes, partition walls, and modular configurations to accommodate different frequencies and positions of vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suspension apparatus is designed to support a transformer of a predetermined size and weight, then vibration reduction is effective for that specific transformer, but the apparatus cannot support transformers of different sizes and weights without redesign
Solution Approach 1:
The vibration reduction unit is designed with a standardized frame structure and resonance space configuration that can be universally applied to transformers of various sizes and weights. The modular design allows the same basic unit to serve multiple transformer types without requiring complete redesign, thus achieving both reliability for vibration reduction and versatility for different applications.
2Reliability
If a suspension apparatus supports the transformer from the bottom side, then vibration generated during operation can be absorbed, but the height of the transformer and suspension apparatus is increased
Solution Approach 1:
Instead of supporting the transformer only from the bottom side (vertical dimension), the vibration reduction unit utilizes horizontal resonance spaces and pipe members that extend in multiple directions. This dimensional change allows vibration absorption to occur in different spatial orientations, maintaining effectiveness while reducing the overall height requirement of the assembly.
3Reliability
If a suspension apparatus is buried in the ground, then vibration can be absorbed, but it cannot be applied to transformers disposed spaced apart from the ground
Solution Approach 1:
The vibration reduction unit introduces an intermediary resonance space and pipe member system between the transformer and the ground (or mounting surface). This intermediary structure allows vibration absorption to occur through resonance in the enclosed space, eliminating the need for direct ground burial while maintaining the vibration absorption function for transformers disposed at various heights.
4Reliability
If a suspension apparatus is configured to support a transformer from the bottom side, then vibration generated during operation can be absorbed, but vibration radiated in different directions cannot be reduced
Solution Approach 1:
The vibration reduction unit incorporates resonance spaces and pipe members at multiple locations and orientations around the transformer. By placing vibration reduction elements with different local qualities (varying resonance frequencies and orientations) at strategic positions, the system can absorb and reduce vibration radiated in different directions simultaneously, rather than only in a single direction.
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 effectively reduces vibrations and noise radiated from transformers by utilizing resonance principles, allowing for adaptable designs that can handle various transformer configurations and vibration patterns, improving noise reduction efficiency and flexibility.
Implementation Method 1
a resonance space formed inside the second frame so as to reduce transmitted vibration or noise by means of resonance
Implementation Method 2
As the transformer operates, a magnetostriction phenomenon occurs in the iron core. Due to the magnetostriction phenomenon, vibration and noise may be generated in the iron core.
