Insulated Pipe Power Supply Structure for Seismic Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bus ducts for electrical power distribution in multi-story buildings are expensive, time-consuming to install and replace, and present high resistance due to rigid conductors, requiring frequent re-torquing and larger footprints for seismic considerations.
Innovation Solution
The proposed solution involves an electrical power supply structure using insulated pipes grouped by phase, supported by longitudinally extending enclosures with transverse conductor support members, and a barrier support plate with tap boxes for secure and rapid connections between sections, allowing for a more efficient and compact distribution system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid conductors with blade-type connections and bolts are used in bus ducts, then secure electrical connection is achieved, but installation time and cost increase significantly
Solution Approach 1:
The bus duct system is divided into modular sections that can be pre-assembled and tested separately, then quickly connected on-site using simplified coupling mechanisms, reducing installation time while maintaining connection security
Solution Approach 2:
The complex mechanical assembly involving multiple bolts and blade-type connections is replaced with a simplified coupling system using fewer fasteners and easier alignment mechanisms, significantly reducing installation time and labor costs
2Reliability
If rigid conductors with blade-type connections are used, then secure electrical connection is achieved, but the number of components and assembly complexity increase
Solution Approach 1:
The connection structure is segmented into standardized interface components with built-in alignment and clamping features, reducing the number of separate parts and simplifying the overall assembly process
Solution Approach 2:
The coupling mechanism is designed as a universal connection type that can accommodate different bus duct configurations and sizes, reducing the variety of unique components needed and simplifying inventory and installation
3Stability of the object's composition
If rigid bus ducts are installed with longer lateral sides perpendicular to structural walls for seismic considerations, then seismic stability is improved, but the area footprint required increases significantly
Solution Approach 1:
The rigid bus duct structure is replaced with a flexible or articulated design that can accommodate seismic movements through controlled deformation or adjustment, maintaining stability without requiring the larger footprint orientation
Solution Approach 2:
Flexible conduits or articulated sections are used in the bus duct design, allowing the system to flex and move during seismic events while maintaining electrical connections, eliminating the need for the perpendicular orientation requirement
