Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling devices for high-voltage distribution cells face challenges in efficiently injecting high-frequency signals while maintaining insulation due to the large ceramic condenser occupying central space, which complicates the placement of a voltage divider and disrupts electric field distribution, compromising electrical safety.
Innovation Solution
The coupling device incorporates an elongated ceramic condenser positioned parallel to the terminal contacts within a DIN C connector, allowing space for a resistive voltage divider arranged in zig-zag form, ensuring compatible electric field distribution and separate connections for both circuits, with an outer resin element housing part of the voltage divider and a synchronization circuit for data input and measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large ceramic condenser is used to achieve high impedance at 50 Hz and low impedance at Mhz frequencies, then the coupling function is improved, but the space available for voltage divider placement is reduced
Solution Approach 1:
The patent transitions from a centralized radial arrangement to a longitudinal arrangement along the connector axis. The condenser is positioned along the central axis while the voltage divider is arranged in a zig-zag pattern parallel to the axis, utilizing the length dimension of the connector rather than competing for radial space. This dimensional reorganization allows both components to coexist without interference.
Solution Approach 2:
The patent divides the connector interior into distinct functional zones: the central axis region houses the condenser for coupling functions, while the peripheral region along the axis accommodates the voltage divider resistances. This segmentation allows each component to be optimally positioned for its specific function without compromising the other.
2Area of stationary object
If the voltage divider is placed at the connection end to utilize available space, then space utilization is improved, but electric field distribution deteriorates
Solution Approach 1:
The patent assigns different spatial qualities to different regions: the central axis region provides a high-voltage environment suitable for the condenser, while the peripheral longitudinal region provides a lower-voltage environment suitable for the voltage divider. The zig-zag arrangement of resistances further optimizes local field distribution by distributing voltage gradients along the axis rather than concentrating them at the connection end.
3Reliability
If the condenser occupies the central position, then coupling performance is improved, but the complexity of arranging both condenser and voltage divider increases
Solution Approach 1:
The patent resolves arrangement complexity by utilizing the longitudinal dimension along the connector axis. The condenser is positioned centrally along the axis, and the voltage divider is arranged in a zig-zag pattern parallel to the axis, effectively using the length of the connector to accommodate both components without complex three-dimensional routing.
