Sliding Rail Submodule Mounting for Heavy Cabinet Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power compensator systems face difficulties in easily mounting and replacing heavy submodules, particularly in modular multilevel converter (MMC) type Static Synchronous Compensator (STATCOM) facilities, due to the complexity and weight of these components.
Innovation Solution
An apparatus is designed with a sliding rail part installed on one side of the cabinet and a sliding guide part on the submodule, allowing for easy entry and withdrawal of submodules, utilizing an oil-free bearing mechanism for smooth movement and enabling efficient replacement of faulty components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional power compensator structure is used, then the system provides stable power compensation, but the mounting and replacement of heavy submodules becomes difficult and complex
Solution Approach 1:
The patent introduces a sliding mechanism that transforms the static mounting structure into a dynamic one. The submodule can slide along the cabinet side wall through guide rails and guide grooves, allowing easy insertion and removal without complex lifting equipment. This dynamic structure resolves the contradiction by enabling simple operation while maintaining structural integrity.
Solution Approach 2:
The patent introduces intermediary components (sliding guide rails, guide grooves, and positioning structures) that mediate between the heavy submodule and the cabinet structure. These intermediaries facilitate easy submodule handling by distributing forces and providing guided movement paths, thereby improving ease of operation without requiring complex external mounting equipment.
2Power
If the submodule is made heavy with more internal devices, then the power compensation capability increases, but the ease of mounting and replacement decreases
Solution Approach 1:
The sliding mechanism allows heavy submodules to be moved horizontally along guide rails rather than requiring vertical lifting. This dynamic approach enables operators to easily insert and remove heavy submodules by simply sliding them into position, thereby maintaining ease of operation even as submodule weight and power capability increase.
Solution Approach 2:
The patent employs support structures and guide rails that bear the weight of heavy submodules during insertion and removal operations. The cabinet structure and mounting apparatus provide counterbalancing support, allowing operators to handle heavy submodules without requiring excessive manual force or specialized lifting equipment.
3Loss of time
If the submodule replacement process is simplified, then maintenance time is reduced, but the structural requirements for easy removal increase
Solution Approach 1:
The sliding mechanism provides a simple linear motion path for submodule replacement. Operators can quickly remove and install submodules by sliding them along the guide rails, significantly reducing maintenance time. The structural complexity is minimized by using straightforward guide grooves and positioning features rather than complex locking or disassembly mechanisms.
Solution Approach 2:
The cabinet structure is pre-configured with guide rails, guide grooves, and positioning structures that prepare the mounting path in advance. This preliminary structural arrangement ensures that submodule replacement requires only simple sliding motions, thereby reducing maintenance time without requiring complex operational procedures or tools.

AI summary
An apparatus of sliding a submodule includes a sliding rail part installed on one side of a cabinet; a submodule capable of being entered into or withdrawn from the cabinet; and a sliding guide part installed at one side of the submodule and slidingly moved by the sliding rail part. The sliding rail part may include a rail body, first and second extending parts extending from opposite ends of the rail body, and first and second sliding rails connected to the first and second extending parts respectively and protruding toward the sliding guide part.
