1Reliability
If multiple independent cooling circuits are used for different heating components, then each component can be cooled independently, but the line configuration becomes complex and the number of components increases
Solution Approach 1:
The patent merges multiple independent cooling circuits into a single integrated cooling circuit. The pump station unit serves as a common power source that distributes cooling medium to multiple heating components (converter cabinet, transformer, generator, shaft system) through a unified line configuration, reducing the number of pumps and simplifying the overall system layout while maintaining independent cooling control through flow distribution.
2Reliability
If multiple independent cooling circuits are used for different heating components, then each component can be cooled independently, but the number of components increases
Solution Approach 1:
The pump station unit is designed as a universal multi-functional component that serves all cooling circuits simultaneously. Instead of having separate pumps for each heating component, the single pump station unit distributes cooling medium to the converter cabinet, transformer, generator, and shaft system, reducing the total number of cooling components while maintaining the ability to cool each component independently.
3Ease of operation
If a decentralized cooling system is used with separate pumps for each circuit, then each cooling circuit operates independently, but the system loss increases
Solution Approach 1:
By merging multiple cooling circuits into one integrated system with a single pump station, the patent reduces the number of moving parts and potential failure points. The unified cooling circuit reduces energy losses associated with multiple independent pump operations while maintaining independent cooling control through flow distribution to different heating components.
