Circuit Breaker Interlock Display System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult to determine which circuit breaker belongs to which interlock group when multiple groups of electrically interlocked circuit breakers exist.
Innovation Solution
An interlock display system for circuit breakers is implemented, featuring a plurality of groups with at least three electrically interlocked circuit breakers and an interlock device that sets matching patterns, with a display section showing the interlocked state and pattern type for each circuit breaker, using LEDs to differentiate between groups through distinct light colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple groups of electrically interlocked circuit breakers are implemented, then the interlocking functionality is improved, but it becomes difficult to determine which circuit breaker belongs to which interlock group
Solution Approach 1:
The patent applies color-coded LED indicators to visually represent different interlock groups. Each group is assigned a specific color (e.g., Group 1: blue, Group 2: red, Group 3: green), allowing operators to immediately identify which circuit breaker belongs to which interlock group through color differentiation, thereby resolving the information loss problem while maintaining multiple interlocking groups
Solution Approach 2:
The patent segments the interlock display information by providing separate display sections for each interlock group within the circuit breaker interface. Each group's status, pattern, and identification information are displayed in distinct segmented areas, enabling clear visual separation and identification of multiple interlock groups simultaneously

AI summary
Provided is an interlock display system of a circuit breaker (1, 2, 3), including: a plurality of groups (501, 502, 503), each of which is configured to include at least three circuit breakers which is electrically interlocked in relative manner and an interlock device (4) that sets matching patterns as interlock targets of the three circuit breakers, and a plurality of the interlock devices (4) are connected with a wire (7, 8) between the groups. An interlock display section (6) that displays an interlock state of the circuit breakers in the group thereof is provided for each of the circuit breakers. A type of pattern and a type of group are displayed on the interlock display section. It is possible to determine which circuit breaker belongs to which interlock group using an electrical display of a circuit breaker main body even when a plurality of groups exist, in which electrical interlocking is performed.
