Switchgear Aperture Cover for Simplified Cable Drawing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing switchgear housing structure requires removal of multiple parts, including a back cover and width direction frame, and temporary fixing of the frame to facilitate cable drawing, leading to increased installation time due to complex preparation and restoration processes.
Innovation Solution
A switchgear with an aperture portion opened from the floor plate to the side wall, featuring a cover member that can be easily attached and detached, allowing horizontal movement of the housing to draw in external cables without interfering with the cable, simplifying the installation process by allowing cable drawing and ground bus attachment on the front side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the back cover and width direction frame are removed to facilitate cable drawing, then the cable can be drawn into the switchgear, but the number of parts to remove increases and temporary fixing is required
Solution Approach 1:
The housing is divided into a main body and a detachable cover portion that can be separately removed. This segmentation allows the cover to be taken off for cable access while the main housing structure remains intact, reducing the number of parts that need to be removed and simplified the cable drawing operation.
Solution Approach 2:
The cover portion is extracted as a separate detachable component from the main housing. This extraction enables the cover to be removed for cable access and then reattached, eliminating the need to remove multiple structural parts and temporary fixing operations.
2Ease of operation
If the width direction frame is temporarily fixed to a frame fixing portion, then the cable path is cleared, but additional fixing work and restoration work are required
Solution Approach 1:
The housing is segmented into a main body and a detachable cover portion. This segmentation allows the cover to be removed for cable access and then reattached without requiring temporary fixing and subsequent restoration work, thereby reducing installation time.
Solution Approach 2:
The cover portion is extracted as a separate detachable component. This design enables the cover to be removed for cable drawing operations and then reattached to restore the housing, eliminating the need for temporary fixing and restoration work associated with the width direction frame.
3Ease of operation
If multiple parts are removed and temporarily fixed for cable drawing, then the cable can be installed, but the installation time increases due to preparation and recovery work
Solution Approach 1:
The housing is segmented into a main body and a detachable cover portion. This segmentation allows for quick removal of the cover for cable access and rapid reattachment, eliminating the need for multiple parts removal and temporary fixing, thereby significantly improving installation speed and productivity.
Solution Approach 2:
The cover portion is extracted as a separate detachable component that can be quickly removed and reattached. This design streamlines the cable installation process by eliminating complex preparation and recovery work, thus enhancing installation productivity.

AI summary
A switchgear (100) has an aperture portion (1a) opened from a floor plate (13) of a housing (1) to a front face side wall (15), and a cover member covering the aperture portion (1a) is detachably attached. The cover member is configured of a front panel (2), a cover (3), and a frame (4), and an external cable (6) can easily be drawn into an interior of the housing (1) simply by removing the cover member. Also, a ground bus (5) is attached to the frame (4) in a place on an inner side of the housing (1), because of which the frame (4) and the ground bus (5) can be simultaneously removed from the housing (1), and a reduction in time needed for installation work is achieved.
