Modular Touch Protection Layout for Bayed Switch Cabinet Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switch cabinet arrangements ineffectively utilize the interior space for mounting device adapters due to the design of touch protection modules, particularly in baying situations where multiple switch cabinet frames are connected, preventing effective use of the continuous interior space.
Innovation Solution
A modular touch protection module with central and end modules that can be aligned and extended to match the width of a mounting plate, allowing continuous busbars and uninterrupted contact passages across multiple switch cabinet frames, enabling efficient use of the interior space by allowing the touch protection module to extend without interruption between lined-up frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If touch protection modules are designed with fixed width, then manufacturing is simplified, but the utilization of clear installation width of switch cabinet interior becomes ineffective
Solution Approach 1:
The touch protection module is divided into multiple central modules of identical width that can be arranged in series, allowing the overall width to be adapted to different switch cabinet configurations while maintaining standardized manufacturing of individual modules
Solution Approach 2:
The standardized central modules serve multiple functions: they can be used individually or combined in series, work with different end modules, and adapt to various switch cabinet widths while maintaining the same manufacturing process
2Device complexity
If touch protection modules have fixed width, then device structure is simplified, but effective utilization of continuous switchgear cabinet interior space in baying situations is prevented
Solution Approach 1:
The module is segmented into identical central modules that can be connected in series to span multiple switch cabinet frames, enabling continuous busbar arrangements and effective use of baying configurations while keeping individual module designs simple
Solution Approach 2:
Multiple central modules are combined in series between end modules to create extended touch protection modules that span across multiple switch cabinet frames, enabling continuous busbar runs and uninterrupted device adapter mounting surfaces
3Manufacturing precision
If touch protection module does not extend to vertical outer edge of mounting plate, then manufacturing tolerance is easier to control, but mounting capacity for device adapters is reduced
Solution Approach 1:
The touch protection module uses multiple standardized central modules that can be precisely manufactured to fixed dimensions and then assembled in series to achieve different total widths, allowing the module to extend to the mounting plate edge while maintaining easy tolerance control during manufacturing of individual components
