Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power conversion devices, such as photovoltaic inverters and energy storage converters, face challenges in convenient field wiring and maintenance due to the layout of AC and DC wiring areas, which affects system design and field wiring convenience.
Innovation Solution
A power conversion device with a housing containing opposite DC and AC wiring areas, each with a movable door for easy access, and a transformer device connected through the AC wiring area, allowing for flexible arrangement and maintenance, reducing floor area and construction costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the AC and DC wiring areas are arranged in a conventional layout, then the device structure is simple, but the field wiring convenience deteriorates
Solution Approach 1:
The housing is divided into multiple sections with separate movable doors for AC and DC wiring areas, allowing independent access to each wiring region. This segmentation enables maintainers to access specific wiring areas without exposing the entire device, improving field wiring convenience while maintaining a structured device architecture.
2Ease of operation
If the wiring areas are arranged at opposite ends of the power converter, then the field wiring convenience is improved, but the device complexity increases
Solution Approach 1:
The AC and DC wiring areas are positioned at opposite ends of the power converter along its length direction, utilizing the longitudinal dimension of the device. This spatial arrangement allows maintainers to access both wiring areas from opposite sides, significantly improving field wiring convenience by enabling simultaneous or independent access without interference, while the linear arrangement along the length direction keeps the layout manageable.
3Ease of repair
If movable doors are provided at both ends of the housing, then the maintenance accessibility is improved, but the device complexity increases
Solution Approach 1:
The housing is segmented with separate movable doors for AC and DC wiring areas, allowing independent access to each wiring region. This segmentation enables maintainers to access specific wiring areas without exposing the entire device, improving field wiring convenience while maintaining a structured device architecture.
Solution Approach 2:
The movable doors can be opened and closed independently to provide access to the wiring areas. This dynamic access mechanism allows maintainers to open only the necessary door for the specific maintenance task, improving maintenance accessibility while keeping the housing structure adaptable rather than permanently complex.
4Adaptability or versatility
If multiple power conversion devices are arranged adjacent to the transformer device, then the power configuration flexibility is improved, but the floor area increases
Solution Approach 1:
The power conversion devices are arranged vertically or in stacked configurations rather than only horizontally, utilizing the vertical dimension to increase power configuration flexibility. This multi-dimensional arrangement allows multiple devices to be positioned adjacent to the transformer device while minimizing the horizontal floor area occupied by the integrated machine.
