Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thyristors are used in SVC switch assemblies, then reactive power compensation function is achieved, but the assembly becomes heavy and bulky making it difficult to handle
Solution Approach 1:
The switch assembly is divided into multiple modular units, each containing a thyristor, cooling plate, and supporting member as an integrated module. This segmentation allows the heavy components to be handled in smaller, more manageable units that can be easily transported and installed, while still achieving the required reactive power compensation function when assembled together.
2Power
If multiple thyristors are connected in series to handle high voltage and current, then the reactive power compensation capability is improved, but the weight and volume of the assembly increase
Solution Approach 1:
The supporting member integrates multiple functions: it provides mechanical support for the thyristor, serves as a heat dissipation structure, and acts as an insulating barrier. By merging these functions into a single integrated component, the assembly achieves high voltage and current handling capability through proper component arrangement without adding unnecessary weight from separate supporting structures.
3Reliability
If proper insulation and heat dissipation structures are added to thyristor assembly, then the reliability and performance are improved, but the device complexity increases
Solution Approach 1:
The cooling plate serves dual purposes: it provides heat dissipation for the thyristor and simultaneously acts as an insulating structure. The supporting member also performs multiple functions including mechanical support, insulation, and heat dissipation. This multi-functionality reduces the need for separate dedicated components, thereby simplifying the overall assembly structure while maintaining reliable insulation and heat dissipation performance.
