UHF Sensor Holding System for High-Voltage Substation Portholes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UHF sensor installation systems for high-voltage substations are cumbersome, require specialized tools, and lack protection against weather conditions, making them unsuitable for outdoor installations and incompatible with certain substation configurations.
Innovation Solution
A holding system for UHF sensors that allows for tool-free installation on high-voltage substation portholes, featuring a fixing element with a locking mechanism and hermetic sealing to protect against weather, designed for easy adaptation to various substation shapes and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a stud system is used to fasten the holding system to the support, then the holding system can be securely attached, but it becomes incompatible with downward-facing windows and requires specialized tools for installation
Solution Approach 1:
The holding system is divided into separate functional components: a fixing element that attaches to the support, a holding piece that secures the sensor, and a locking member that connects them. This segmentation allows each component to be optimized independently, enabling the locking member to engage from multiple directions and making the system compatible with downward-facing windows without compromising attachment strength.
Solution Approach 2:
Instead of using a stud system that requires fastening from above, the locking member is designed to engage and lock the holding piece to the fixing element from any orientation. The locking mechanism inverts the traditional fastening approach by using a detachable locking member that can be manually engaged without specialized tools, thereby achieving both secure attachment and versatility across different window configurations.
2Ease of operation
If the UHF sensor is exposed externally on the porthole, then access to the porthole is maintained, but the sensor lacks protection against weather conditions and is at risk of damage
Solution Approach 1:
The holding piece is designed to partially house the UHF sensor within its structure, creating a nested configuration where the sensor is protected by the holding piece while still allowing acoustic signals to pass through to the porthole. This nesting provides weather protection for the sensor without blocking access to the porthole, as the holding piece's material and geometry are optimized to transmit UHF frequencies while shielding the sensor from environmental factors.
3Adaptability or versatility
If a complex fixing element is designed to accommodate various substation configurations, then adaptability is improved, but the device complexity increases
Solution Approach 1:
The fixing element is designed with a universal interface that can attach to different support types and configurations through standardized mounting features. The combination of the fixing element, holding piece, and locking member creates a multi-functional assembly that can accommodate various substation shapes and orientations without requiring custom-designed components for each configuration, thereby achieving adaptability while controlling complexity.
