Centralized-Control Circuit Breaker for Compact Power Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in the communication power supply field is to develop a circuit breaker that is compact, cost-effective, and easily integratable, while maintaining reliable operation and status indication, as the increasing demand for power distribution in intelligent communication systems requires more efficient and smaller circuit breakers.
Innovation Solution
The circuit breaker design incorporates a housing with a mechanical and electronic device, featuring a remote-controlled and wirelessly controllable mechanism, with a bicolor indicator for status display and a pull ring mechanism for easy installation and removal, eliminating the need for an internal controller to save space and reduce costs, and integrating control units on a signal backplane for centralized control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a controller is disposed inside each circuit breaker, then the circuit breaker can operate independently, but the size and costs of the circuit breaker increase
Solution Approach 1:
Multiple control units for different circuit breakers are merged into a single centralized controller disposed outside the circuit breaker housing. This centralized controller manages multiple circuit breakers through a shared control architecture, eliminating the need for individual controllers in each circuit breaker and significantly reducing the overall system size and cost.
2Adaptability or versatility
If more circuit breakers are configured in the power shelf to meet increasing power distribution requirements, then the power distribution capability is improved, but the space occupation and system complexity increase
Solution Approach 1:
The centralized controller is designed with multi-functionality to manage multiple circuit breakers simultaneously. It can control different circuit breakers for various power distribution tasks through a unified interface and control logic, enabling the system to handle increasing power distribution requirements without proportionally increasing system complexity.
3Reliability
If a controller is disposed inside each circuit breaker, then the control function is complete, but the costs of the circuit breaker increase
Solution Approach 1:
The control functions for multiple circuit breakers are merged into a single centralized controller. This approach reduces the total number of controllers needed, lowering component costs, assembly complexity, and manufacturing expenses while maintaining complete control functionality across all circuit breakers in the system.

AI summary
A circuit breaker and a power distribution system are provided. The circuit breaker includes a housing and an internal element disposed inside the housing. The housing includes a front panel and a rear panel that are disposed opposite to each other, the front panel is disposed with a button, a status display unit, and a power wiring port, and the rear panel is disposed with a power interface and a signal interface. The power wiring port and the power interface are connected to a circuit of a power distribution system. The signal interface is internally and electrically connected to the button, the status display unit, and the internal element, and the signal interface is externally configured to be electrically connected to a control unit disposed outside the housing. A control signal of the control unit implements working of the button, the status display unit, and the internal element.
