Integrated Switchgear Module With Interlocked Isolator and Grounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical assemblies for medium-voltage and high-voltage switchgear installations are not space-efficient due to separate modules for isolator, circuit breaker, and ground electrode functions, leading to unnecessary use of support elements and mating contacts.
Innovation Solution
Integration of isolator, circuit breaker, and ground electrode functions into a single module, where components share functions and support structures, reducing the need for additional parts and optimizing spatial arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If isolator, circuit breaker, and ground electrode functions are implemented as separate modules, then each function can be independently designed and maintained, but the overall assembly occupies excessive space and requires additional support elements and mating contacts
Solution Approach 1:
The patent combines the isolator, circuit breaker, and ground electrode functions into a single integrated module. The isolator blade, circuit breaker contacts, and ground electrode blades share common support structures and mounting mechanisms, eliminating the need for separate support elements and reducing the overall assembly footprint while maintaining independent functionality of each component
Solution Approach 2:
The module design employs universal support structures that serve multiple functions: the same support elements hold the isolator blade, circuit breaker contacts, and ground electrode blades. The mating contacts are designed to accommodate all three functions within a single interface, reducing the total number of parts required
2Stability of the object's composition
If separate modules are used for each function, then component independence is maintained, but the number of support elements and mating contacts increases
Solution Approach 1:
The patent merges the support structures for isolator, circuit breaker, and ground electrode into a common framework. The same support elements and mounting mechanisms are used across all three functions, significantly reducing the total number of parts while preserving the functional independence and operational stability of each component
3Area of stationary object
If functions are integrated in a common module, then space efficiency is improved, but the spatial arrangement of components becomes more complex
Solution Approach 1:
The patent arranges the isolator blade, circuit breaker contacts, and ground electrode blades in a compact three-dimensional configuration within the module. Components are positioned in different spatial planes and orientations, allowing efficient use of available space while maintaining proper clearance and operational movement for each element

AI summary
An electrical assembly has an isolator function, a circuit breaker function and at least one ground electrode function. The at least one ground electrode function, the isolator function and the circuit breaker function are integrated in one and the same module. A locking unit is integrated in the module. The locking unit subjects the isolator function, the circuit breaker function and the at least one ground electrode function to mutual interlocking.
