Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power distribution modules in switchgears have an unreasonable wire layout, leading to large occupied space and low arrangement density, making installation and maintenance difficult and inflexible.
Innovation Solution
The power distribution module is designed with a body that can slide between operation, test, and disconnection positions, featuring a wire incoming end and wire connection end arranged on the connection side along the height direction, optimized for space usage and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wire incoming end and wire connection end are arranged on opposite sides of the power distribution module, then the wiring is simplified, but the module occupies large space and arrangement density is low
Solution Approach 1:
The patent merges the wire incoming end and wire connection end onto the same connection side of the power distribution module, specifically arranging them at different heights on the front face. This combining approach allows both wiring functions to be accessed from one side, simplifying the overall wiring structure while reducing the space required compared to having wires enter from opposite sides of the module.
Solution Approach 2:
The patent utilizes the height dimension (vertical arrangement) to differentiate the wire incoming end and wire connection end. By arranging these components at different heights on the same connection side rather than spreading them across opposite sides horizontally, the design optimizes space utilization while maintaining wiring simplicity.
2Stability of the object's composition
If the power distribution module uses a fixed structure, then the installation is stable, but the arrangement density and flexibility are reduced
Solution Approach 1:
The patent implements a sliding mechanism that allows the power distribution module to move horizontally along guide rails between a working position and a withdrawn position. This dynamic capability enables the module to be easily installed, removed, and repositioned, significantly improving arrangement flexibility and adaptability while maintaining stable electrical connections during operation through the interlocking mechanism.
Solution Approach 2:
The power distribution module is designed as a separable, modular unit that can be independently installed and removed from the switchgear cabinet. This segmentation allows for flexible arrangement configurations and easy maintenance without affecting other components, while the interlocking mechanism ensures stable connection when in the working position.
3Ease of operation
If the power distribution module occupies large space, then the wiring accessibility is improved, but the arrangement density in the switchgear is low
Solution Approach 1:
The patent arranges both the wire incoming end and wire connection end on the front connection side of the module at different heights, utilizing the vertical dimension to provide adequate wiring accessibility. This vertical stacking approach allows wires to be accessed from the front without requiring excessive horizontal space, thereby increasing the number of modules that can be arranged in the switchgear cabinet.
Solution Approach 2:
By combining both wire incoming and wire connection functions on the same side of the module, the patent eliminates the need for additional space on the opposite side, reducing the overall footprint of each module while maintaining full wiring accessibility from the front, thus improving arrangement density.

AI summary
Embodiments of the present disclosure provide a power distribution module for a switchgear and a switchgear. The power distribution module comprises a body adapted to be slidably connected to a fixed base plate of the switchgear in an installation direction to switch between at least an operation position, a test position and a disconnection position; a wire incoming end arranged on a connection side of the body toward a junction box of the switchgear and adapted to be electrically connected to an output end of the junction box after the body reaches the operation position; and a wire connection end arranged at intervals from the wire incoming end on the connection side and adapted to be electrically connected to an adapter end of the junction box after the body reaches the operation position or the test position. Accordingly, the mounting density of the power distribution modules in the switchgear can be increased, and the arrangement flexibility of the power distribution modules in the switchgear is improved.
