Power Distribution Subrack Layout for Shared Breaker Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power distribution subracks waste space and increase material costs due to redundant controllers when circuit breakers with different specifications are mixedly plug-connected, as each breaker is controlled by a single controller, leading to idle controllers.
Innovation Solution
The power distribution subrack design connects second ends of at least two connection terminals to a single controller, allowing shared control of multiple circuit breakers, reducing the number of controllers needed and optimizing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each circuit breaker is controlled by a single dedicated controller, then the control reliability is improved, but the number of controllers increases, leading to wasted space and increased material costs
Solution Approach 1:
The patent implements a multi-functionality principle by enabling a single controller to manage multiple circuit breakers through shared connection terminals. The controller can dynamically identify and control different circuit breakers based on which connection terminals are actively plugged in, making one controller universal for multiple breaking devices rather than requiring dedicated controllers for each breaker.
Solution Approach 2:
The patent merges the control functions for multiple circuit breakers into a single controller. By combining the connection terminals of multiple circuit breakers and connecting them to a shared controller, the system reduces the total number of controllers while maintaining control capabilities through terminal identification and selective activation.
2Adaptability or versatility
If circuit breakers with different specifications are mixedly plug-connected, then the adaptability is improved, but the number of controllers must increase to cover all breakers, wasting space on the collection board
Solution Approach 1:
The patent applies universality by designing a controller that can adaptively manage circuit breakers of different specifications. The controller identifies which connection terminals are actively used and controls only those corresponding circuit breakers, making a single controller universal for handling various breaker types and sizes without requiring dedicated controllers for each specification.
Solution Approach 2:
The system implements dynamics by enabling the controller to dynamically identify and activate only the connection terminals and corresponding circuit breakers that are currently plugged in. This dynamic adaptation allows the system to handle mixed specifications efficiently, activating control functions only when needed rather than maintaining static dedicated controllers for all possible breaker configurations.
3Manufacturing precision
If dedicated controllers are disposed for each connection terminal, then the control precision is improved, but the material costs and space occupation increase due to idle controllers
Solution Approach 1:
The patent achieves universality by designing a controller that can precisely control multiple circuit breakers through shared connection terminals. The controller maintains control precision by identifying which terminals are actively connected and selectively controlling the corresponding breakers, eliminating the need for multiple dedicated controllers while preserving precise control capabilities.
Solution Approach 2:
The system implements self-service by enabling the controller to automatically identify which connection terminals are actively plugged in and which circuit breakers need control. The controller autonomously manages its own task allocation, activating only the necessary control functions for currently connected breakers rather than requiring manual configuration or dedicated controllers for each terminal.
