Modular Tap-Off Box for Busbar Trunking Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air-insulated busbar systems installed horizontally pose accessibility challenges for tap-off points located at the top or bottom, as traditional tap-off boxes must be positioned on top or bottom, making safer side access more expensive and less efficient.
Innovation Solution
A modular tap-off box design with separate modules, one for contact arrangements and another for switching functions, featuring housings open on one side with adaptable designs and interfaces, allowing for easier access and variable placement, including side installation to accommodate both horizontal and vertical configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tap-off box is arranged on top or bottom of busbar pack, then optimal electrical utilization through vertical ventilation is achieved, but accessibility of the tap-off box becomes disadvantageous
Solution Approach 1:
The tap-off box is divided into separate modules: a first module for contact arrangements and a second module for switching functions. Each module has an open side housing that can be independently positioned and accessed, allowing the contact module to remain on top/bottom for ventilation while the switching module can be accessed from the side.
Solution Approach 2:
The invention transitions from a single monolithic tap-off box to a multi-dimensional modular arrangement where different functional modules can be positioned in different spatial orientations. The open side housing design enables access from multiple directions (top, bottom, left, right), adding dimensional flexibility to the installation configuration.
2Ease of operation
If separate modules with open side housings are used, then accessibility from side is improved, but housing complexity increases
Solution Approach 1:
The complex housing structure is segmented into standardized modular components with open sides. Each module (contact arrangement module, switching device module) has a simplified open-side housing design that can be independently manufactured and assembled, reducing overall system complexity despite multiple components.
Solution Approach 2:
The open side housing design serves multiple functions: it provides side accessibility for operation, maintains structural integrity for mounting, and allows for modular assembly/disassembly. This universal design approach simplifies each individual module while enabling complex system configurations.
3Adaptability or versatility
If modular design with separate functional units is implemented, then adaptability to different applications is improved, but manufacturing complexity increases
Solution Approach 1:
The tap-off box is segmented into standardized functional modules (contact arrangement module, switching device module) that can be manufactured independently using standardized processes. Each module has a uniform open-side housing design that simplifies manufacturing while allowing customization of internal components for different applications.
Solution Approach 2:
Functional modules are pre-assembled and tested as complete units with integrated housings before final installation. The open side housing is designed as a preliminary structural framework that accommodates various functional components, allowing parallel manufacturing of multiple modules that are later assembled into the complete system.
