Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuse switch disconnector systems require a large number of different adapters for mounting 1-pole and 4-pole versions on busbars, leading to increased manufacturing, storage, and installation costs.
Innovation Solution
A fuse switch disconnector system with a mounting adapter that uses a single adapter for both 1-pole and 4-pole versions, featuring adapter hooks and clamping devices for secure electrical and mechanical coupling to busbars, and an insulating adapter hook for isolation, reducing the number of parts and assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple different adapters are used for mounting 1-pole and 4-pole fuse switch disconnectors, then proper electrical coupling is achieved, but manufacturing, storage, and installation costs increase
Solution Approach 1:
The mounting adapter is designed with multiple conductor sections (first conductor section for L1, second conductor section for L2, third conductor section for L3) that can be selectively connected to different busbars. This universal design allows a single adapter to accommodate both 1-pole and 4-pole fuse switch disconnectors, eliminating the need for multiple different adapter types while maintaining proper electrical coupling for each pole configuration
Solution Approach 2:
The mounting adapter is divided into separate functional modules: conductor sections for electrical coupling, adapter hooks for mechanical attachment, and connection sections for busbar interface. This segmentation allows flexible configuration where only the necessary conductor sections and adapter hooks are activated for each specific application (1-pole or 4-pole), reducing complexity while ensuring reliable electrical coupling
2Reliability
If multiple different adapters are used for mounting 1-pole and 4-pole fuse switch disconnectors, then proper electrical coupling is achieved, but storage and installation costs increase
Solution Approach 1:
A single universal mounting adapter design serves both 1-pole and 4-pole fuse switch disconnectors. The adapter includes all necessary conductor sections and adapter hooks, but only the required portions are connected based on the specific application. This eliminates the need to manufacture, store, and manage multiple different adapter types, significantly reducing inventory requirements and installation complexity
3Strength
If adapter hooks are used for mechanical coupling to busbars, then secure mounting is achieved, but electrical interference may occur without insulation
Solution Approach 1:
The third adapter hook is designed as an electrical insulator that acts as an intermediary between the mounting adapter and the third busbar. This insulating adapter hook provides the necessary mechanical coupling strength for secure mounting while simultaneously preventing electrical interference or unintended electrical connections, allowing the same adapter design to safely interface with both conductive and non-conductive busbars
