Embedded Conductor Breaker Structure for Conductive Gas Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breaker devices suffer from conductive gas attributed to electric arcs leaking out, which can cause insulation deterioration on external members.
Innovation Solution
A breaker device incorporating a resin member with an internal space and a plate-shaped conductor, featuring a first and second holding portion embedded in the resin member, and a connecting portion, designed to minimize gas leakage by containing the conductive gas within the resin member's internal space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cutoff portion is cut off in the state where an electric current flows to the conductor, then the circuit interruption function is achieved, but an arc discharge occurs and conductive gas leaks out of the housing
Solution Approach 1:
The resin member acts as an intermediary barrier between the conductor and the external environment. It includes a through-hole that allows the conductor to pass through while the resin material itself contains and suppresses the conductive gas generated by arc discharge, preventing it from leaking outward to external members.
Solution Approach 2:
The resin member functions as a flexible containment structure that surrounds the conductor and the arc discharge region. The resin material provides a protective barrier that contains the conductive gas within the breaker device housing, preventing its escape to external components.
2Reliability
If the conductor is embedded in the resin member, then the conductor is securely held and gas leakage is reduced, but the manufacturing complexity increases
Solution Approach 1:
The conductor and resin member are merged into a single integrated structure where the conductor is embedded within the resin. This combining of elements simplifies the overall device structure by eliminating separate fixation mechanisms while simultaneously providing both secure conductor holding and gas containment functions.
Solution Approach 2:
The breaker device utilizes a composite structure combining conductive material (conductor) and insulating resin material. This composite design allows the conductor to be embedded in the resin, providing both mechanical support and gas containment without requiring additional complex components.
