T-Connector Measuring Socket Assembly for Stray Capacitance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
T-connectors used in electrical power grids often have varying geometries, leading to gaps or air-filled areas when measuring devices are inserted, causing voltage flashovers and stray capacitances, which result in inaccurate measurements, especially with capacitive electrode arrangements.
Innovation Solution
A T-shaped connector assembly with a measuring device featuring a coupling element and a capacitor assembly where the second electrode protrudes into the receiving area of the measuring socket, bridging any gaps and ensuring a flush fit to minimize interferences, and the measuring device's insertion area is designed to accommodate various socket geometries by being longer than or equal to the receiving area depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the measuring device is designed with a fixed insertion area length, then it can be precisely adapted to one specific connector geometry, but it cannot be used with connectors of different geometries
Solution Approach 1:
The measuring device is designed with a universal insertion area that can accommodate multiple connector geometries. The insertion area length is set to be greater than or equal to the receiving area depth of various connectors, allowing the same measuring device to function with different connector types without requiring design modifications.
2Reliability
If the receiving area depth is increased to accommodate longer insertion areas, then gaps are eliminated, but the measuring socket becomes more complex and larger
Solution Approach 1:
The insertion area is designed to extend beyond what is strictly necessary for any single connector type. By making the insertion area length greater than or equal to the receiving area depth, the design ensures complete insertion and gap elimination for all common connector geometries without requiring each socket to be customized to maximum depths.
3Device complexity
If gaps are allowed between the measuring device and measuring socket, then the design is simplified, but stray capacitances and voltage flashovers occur
Solution Approach 1:
The design proactively prevents gap formation by dimensioning the insertion area to ensure complete insertion into the receiving area. The insertion area length is predetermined to be sufficient for all common connector geometries, eliminating the need for complex adjustment mechanisms or post-assembly gap correction.
