DC Distribution Panel Unit and Migration Device Integration

Solution Overview

Problem

Conventional 19-inch rack systems require new DC distribution panels and migration devices when loads adapt to high voltage DC power feeding, leading to increased costs and space requirements due to the need for separate components.

Innovation Solution

The DC distribution panel unit and migration device are designed to be structurally and positionally compatible, allowing them to replace each other, eliminating the need for additional DC distribution panels and reducing the necessity of maintaining 19-inch racks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If migration devices are stored in separate 19-inch racks, then AC loads and DC loads can be powered, but additional DC distribution panels are required when loads adapt to high voltage DC power feeding, increasing cost and space requirements

Engineering Contradiction:

Improveadaptability to high voltage DC power feedingVSAvoidspace requirements

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines the migration device and DC distribution panel into a single integrated unit. The migration device includes a housing that accommodates both the conversion components (for converting high voltage DC to AC or low voltage DC) and the DC distribution panel components (breakers, terminals, busbars). This merging eliminates the need for separate 19-inch racks and additional DC distribution panels, thereby reducing space requirements while maintaining adaptability to high voltage DC power feeding.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated migration device performs multiple functions within a single unit: it converts high voltage DC to AC for AC loads, converts high voltage DC to low voltage DC for DC loads, and simultaneously serves as a DC distribution panel with protective devices and distribution terminals. This multi-functionality allows the system to adapt to high voltage DC power feeding while eliminating the need for additional separate components, thereby reducing space requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)
