Bidirectional Breaker Slot Layout for Multi-Directional Power Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and cost of breaker configurations in power supply systems with multiple directional connections, such as those involving solar power, wind power, and electric vehicles, are increased due to the need for dedicated breaking units for each direction, leading to a complicated network configuration.
Innovation Solution
A breaker design incorporating a breaking unit capable of bidirectional current interruption and a housing with multiple slots, allowing flexible insertion and pre-wired connections to simplify configurations for multiple directional extensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dedicated breaking units are created for each direction (three directions, four directions, etc.), then the breaker can handle complex multi-directional power networks, but the configuration becomes complicated and costs increase
Solution Approach 1:
The patent applies universality by designing a single breaking unit that can function in multiple directions (two-directional breaking capability) and a housing that accepts the same breaking unit in various slot configurations. This allows one universal breaking unit to replace multiple dedicated breaking units for different directions, thereby reducing device complexity while maintaining adaptability for complex multi-directional power networks
2Adaptability or versatility
If dedicated breaking units are created for each direction (three directions, four directions, etc.), then the breaker can handle complex multi-directional power networks, but the construction cost increases
Solution Approach 1:
The patent reduces construction costs by enabling universal breaking units to be reused across multiple configurations. Instead of manufacturing and installing different dedicated breaking units for each direction, the same breaking unit can be inserted into different slots within the housing to achieve various directional connections, thereby simplifying manufacturing and reducing overall network construction costs
3Device complexity
If a single breaking unit is used for two directions with multiple slots, then the configuration is simplified and costs are reduced, but the breaker must handle current interruption in multiple directions
Solution Approach 1:
The patent applies segmentation by dividing the current interruption function into separate breaking units, each designed to break current in two directions. By segmenting the overall multi-directional breaking requirement into multiple two-directional breaking units arranged in different slots, the system maintains high reliability for current interruption while keeping each individual breaking unit relatively simple and manageable
