Gas-Insulated Sensor Module Compact Housing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for compact yet powerful gas-insulated high-voltage switchgear (GIS) systems poses a challenge as larger electrical power requirements often result in less compact designs due to larger housing dimensions, which complicates the compactness and efficiency of voltage measurement units.
Innovation Solution
A gas-insulated high-voltage measurement unit with at least two primary phase connections arranged parallel to each other, encapsulated in a common housing with separate connection openings, allowing for a single gas filling and reduced housing volume, featuring a flange-like adapter section and ribbed structure for enhanced strength and compactness, and utilizing a dry plug-in contact coupling for assembly and maintenance.

Engineering Contradiction Analysis
1Power
If higher electrical power is required from a GIS with the same protective gas and the same functional structure and materials, then the electrical power increases, but the dimensions of the GIS increase and compactness deteriorates
Solution Approach 1:
The patent divides the multi-phase voltage measuring unit into separate single-phase measuring units, each with its own gas-tight housing and connection opening. This segmentation allows each phase to be independently enclosed, enabling a more compact overall structure while maintaining the required electrical power measurement capability across multiple phases.
Solution Approach 2:
The patent transitions from a conventional multi-phase encapsulation approach to a configuration where single-phase measuring units are arranged in a specific spatial dimension with elongated cross-section. The primary phase connections are arranged in a common plane, and the housing cross-section is elongated perpendicular to this plane, optimizing the dimensional arrangement to reduce overall GIS footprint while handling higher electrical power.
2Volume of moving object
If multiple phase connections are encapsulated together in a gas space, then the housing volume is reduced, but the complexity of gas handling and assembly increases
Solution Approach 1:
Instead of encapsulating multiple phase connections together in a single gas space, the patent segments each phase into its own gas-tight housing with separate connection openings. This eliminates the complexity of gas handling for multi-phase connections while maintaining compact housing volume through optimized spatial arrangement of the segmented units.
Solution Approach 2:
Each single-phase measuring unit is designed as a self-contained, gas-tight module that can be independently assembled, tested, and maintained. The separate connection openings allow each unit to be serviced independently without affecting other phases, simplifying gas handling procedures while maintaining compact overall dimensions.
3Ease of operation
If separate gas compartments are used for each phase connection, then gas handling is simplified, but the housing volume and device complexity increase
Solution Approach 1:
The patent merges the benefits of separate gas compartments with compact housing design by arranging single-phase measuring units with separate connection openings in an optimized spatial configuration. Each phase has its own gas-tight enclosure simplifying gas handling, while the overall housing volume is minimized through the elongated cross-section design and common plane arrangement of primary phase connections.

AI summary
The unit (1) has primary phase connections (5-7) arranged in a plane such that an integrated, sleeve-like housing (3) includes a drawn out housing cross-section in a sectional plane. A housing length is larger than a housing breadth. The connections and measuring units (8) are commonly encapsulatedly arranged in a gas compartment (16) of the housing. The housing includes two housing flanges, which extend in a direction of the housing length and are arranged opposite to each other. One of the housing flanges includes a reinforcement rib acting against absolute pressure.
