Modular Insulating Arrangement for Gas-Insulated Switchgear

Solution Overview

Problem

Existing disk-shaped insulating systems for electrical insulation have limited variability and laborious assembly processes, making them unsuitable for flexible applications, especially in gas-insulated switchgear.

Innovation Solution

A modular insulating system comprising two or more sub-elements with electrically insulating properties, allowing for independent shaping and assembly, with a joining gap and fluid-tight sealing capabilities to create a variable and easily assembled insulating arrangement that can span openings and maintain a hermetic barrier.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a one-piece insulating arrangement is used, then angular rigidity and reliable electrical insulation are improved, but variability and ease of assembly deteriorate

Engineering Contradiction:

Improveelectrical insulation reliabilityVSAvoidsystem variability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The insulating arrangement is divided into multiple modular sub-elements that can be independently manufactured, configured, and assembled. Each sub-element maintains electrical insulation properties while the modular structure enables variable configurations to suit different application requirements, resolving the contradiction between reliability and adaptability.

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If a one-piece insulating arrangement is used, then angular rigidity is improved, but ease of assembly deteriorates

Engineering Contradiction:

Improveangular rigidityVSAvoidassembly ease

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The insulating arrangement is divided into multiple modular sub-elements that can be independently manufactured, configured, and assembled. Each sub-element maintains electrical insulation properties while the modular structure enables variable configurations to suit different application requirements, resolving the contradiction between reliability and adaptability.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If multiple sub-elements are used to improve variability and ease of assembly, then adaptability and ease of assembly are improved, but the number of sealing areas and joining gaps increases

Engineering Contradiction:

Improvesystem variabilityVSAvoidnumber of sealing areas and joining gaps

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple sub-elements are connected through merging their functional features to form an integrated insulating arrangement. The connections between sub-elements are designed to minimize sealing areas and joining gaps, effectively reducing the overall complexity despite the modular structure. This approach maintains adaptability while mitigating the increase in sealing requirements.

Inventive Principle:

Principle #5Merging (Combining)
