Vertical Busbar Support With Notched Strip Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vertical electrical busbar support systems face challenges in securely supporting the weight of stacked busbars and preventing separation due to short circuit forces, as they rely on friction and lack positive engagement to maintain busbar positioning.
Innovation Solution
A vertical electrical busbar support system featuring notched conductive strips engaging with horizontal pins within grooves on insulating support members, providing secure vertical support and reducing the need for excessive physical connections, which can enhance thermal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual busbars are retained in grooves by friction and clamping, then the busbars are held in position, but there is no positive engagement to prevent movement along the groove and support the weight of vertically arranged busbars
Solution Approach 1:
The support member is divided into multiple vertical grooves, each engaging a separate busbar. The horizontal support member spans across these vertical grooves, creating segmented engagement points that collectively support the entire busbar stack without requiring a single complex structure.
Solution Approach 2:
The invention transitions from purely vertical engagement (friction-based) to adding horizontal engagement through the horizontal support member that spans across vertical grooves. This dimensional addition creates positive engagement in both vertical and horizontal directions, preventing busbar movement along the grooves while supporting weight.
2Reliability
If multiple physical connections are used to support busbars securely, then the busbars are well-supported, but thermal performance deteriorates due to excessive physical connections
Solution Approach 1:
An insulating horizontal support member is introduced as an intermediary element that spans across the vertical grooves. This mediator provides structural support and positive engagement while being electrically insulating, thus minimizing thermal interference and maintaining thermal performance while ensuring secure busbar support.
3Device complexity
If friction-based retention is used in conventional support systems, then the structure is simple, but the busbars cannot be positively engaged to prevent movement along the groove
Solution Approach 1:
The invention merges two engagement mechanisms: vertical engagement through grooves that engage the busbar edges, and horizontal engagement through the horizontal support member that spans across the grooves. This combination of vertical and horizontal engagement elements creates positive engagement in multiple directions while maintaining structural simplicity.
