Engineering Contradiction Analysis
1Reliability
If multi-phase transformers are used for power conversion, then power transformation function is achieved, but replacement time and installation complexity increase significantly
Solution Approach 1:
The patent divides a multi-phase transformer system into multiple independent single-phase transformers. Each single-phase unit can be independently replaced without affecting the others, reducing replacement time from months to days. The segmentation allows parallel operation and simplifies logistics for replacement.
Solution Approach 2:
The single-phase transformers are designed with universal mounting structures and standardized connection points that can accommodate different configurations. The outdoor connection elements can serve multiple functions including electrical connection, grounding, and structural support, reducing installation complexity.
2Reliability
If multi-phase transformers are used for power conversion, then power transformation function is achieved, but transportation and installation complexity increase due to large size and weight
Solution Approach 1:
By segmenting the system into single-phase units, each unit has reduced weight and dimensions compared to a complete multi-phase transformer. This makes transportation easier and allows standard shipping methods to be used, reducing special handling requirements and costs.
Solution Approach 2:
The patent introduces outdoor connection elements as intermediaries between the single-phase transformers and the power system. These connection elements simplify the interface requirements, allowing standard mounting procedures and reducing installation complexity at the installation site.
3Adaptability or versatility
If single-phase transformers are distributed over large area, then flexibility in setup is improved, but connection complexity to power system lines increases
Solution Approach 1:
The outdoor connection elements are designed with universal mounting structures and standardized connection interfaces that can accommodate different power system configurations. Each connection element provides multiple functions including electrical connection, mechanical support, and grounding, simplifying the overall connection process despite distributed positioning.
Solution Approach 2:
The patent allows for parameter adjustments in the connection elements, such as adjustable mounting heights and configurable connection points. This flexibility enables adaptation to various terrain conditions and power system configurations without increasing connection complexity.
4Adaptability or versatility
If cable connections with lengths between 5 and 50 meters are used, then flexibility in positioning outdoor connections is improved, but cable management complexity increases
Solution Approach 1:
The cable connections are integrated with universal mounting structures that provide both electrical connection and mechanical support functions. The cable management system incorporates standardized routing paths and securing mechanisms that work across all connection points, reducing overall system complexity despite the varied cable lengths required for different positioning scenarios.

AI summary
A configuration for replacing a multi-phase transformer includes a plurality of single phase transformers each having a housing which is filled with an insulating fluid and in which a core with a high-voltage winding and a low-voltage winding is disposed. The configuration can be set up flexibly and also connected easily and conveniently to a supply network or consumer network by providing each housing with at least one cable connection and connecting each cable connection through a cable line to an outdoor connection which is air insulated, constructed for outdoor use and set up separately from the housing.
