Flexible Deaeration Tool for Switchgear Connection Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switchgear connection devices fail to effectively remove air from the connection section, leading to air reservoir formation and degradation of insulation properties due to increased air pressure, which compromises the electrical insulation and reliability of the solid-insulated busbar connection section.
Innovation Solution
A deaeration tool with a flexible tubular body, air vent hole, suction device attachment/detachment section, and a suction port is used to discharge air from the connection section without damaging the equipment, ensuring the insulation property is maintained by reducing air pressure to atmospheric levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the first electrical equipment and the second electrical equipment are pressed against each other to achieve tight attachment, then the connection strength is improved, but air pressure increases and air reservoir is produced between the outer wall surface of the connection section and the inner wall surface of the connection surface, degrading insulation property
Solution Approach 1:
The deaeration tool is inserted into the connection section before the pressing operation to establish an air discharge path in advance. This preliminary action ensures that air can escape during the pressing process, preventing air reservoir formation and maintaining insulation properties while achieving tight attachment.
Solution Approach 2:
The deaeration tool acts as an intermediary element between the first and second electrical equipment during the pressing operation. It provides a controlled channel for air to escape from the connection section, mediating between the need for tight attachment and the need to maintain low air pressure for insulation.
2Reliability
If air is removed from the connection section to maintain insulation property, then the insulation property is improved, but additional equipment and process steps are required
Solution Approach 1:
The deaeration function is merged with the connection process by integrating the air discharge path creation into the pressing operation itself. The deaeration tool is inserted and used concurrently with the pressing action, combining two functions (deaeration and connection) into a single integrated process step.
Solution Approach 2:
The connection section itself provides the air discharge path through the deaeration tool insertion, making the system self-servicing for deaeration. The structure of the connection section, when combined with the deaeration tool, automatically creates the necessary air escape route without requiring separate external deaeration equipment.
