Solution Overview
Problem
Existing GIS designs face space limitations due to the conventional placement of current transformers relative to circuit breakers, which restricts compact installation and efficient use of space in substation setups.
Innovation Solution
The proposed GIS arrangement places current transformers between and on either side of the circuit breaker, allowing for a more compact design by packaging the transformers and circuit breaker together within a shared housing, thereby optimizing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If current transformers are placed in conventional positions relative to circuit breakers, then installation space requirements are met, but space utilization efficiency deteriorates
Solution Approach 1:
The patent merges the current transformer and circuit breaker into a single integrated unit, where the current transformer is positioned between the first and second circuit breakers and electrically connected to both. This combination allows shared housing and coordinated installation, improving space utilization while meeting installation space requirements.
2Volume of moving object
If current transformers are positioned to optimize space, then installation space efficiency improves, but structural complexity increases
Solution Approach 1:
The current transformer is integrated with the circuit breakers in a shared housing structure, where the first and second circuit breakers are positioned on opposite sides of the current transformer. This merging approach optimizes space efficiency while managing structural complexity through coordinated design of the integrated unit.
