Burst Temperature Indicator for High-Voltage Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current monitoring technologies, such as dissolved gas analysis (DGA), are inadequate for immediate detection of overheating in high-voltage electrical equipment, as they are subjective and only indicate accumulated gas build-up, failing to respond promptly to threshold temperatures.
Innovation Solution
A burst indicator device is employed, featuring a reservoir with a detectable material and a rupture disk that releases the material when the electrical component reaches a threshold temperature, providing immediate indication of overheating through light emission or acoustic signals, allowing for online monitoring of high-voltage equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dissolved gas analysis (DGA) is used for condition assessment, then gas accumulation trends can be identified, but immediate temperature threshold detection is not achieved
Solution Approach 1:
The patent employs a rupture disk that undergoes a phase transition from intact to burst state when the electrical component reaches a threshold temperature. This phase change enables immediate detection of overheating conditions, resolving the contradiction by providing both precise temperature threshold measurement and instant response time, eliminating the delay inherent in DGA methods
Solution Approach 2:
The patent replaces the chemical analysis system (DGA) with a mechanical rupture disk system that directly responds to temperature-induced pressure changes. This substitution provides immediate mechanical indication of threshold temperature achievement, achieving both measurement precision and rapid response time without the time loss associated with gas accumulation analysis
2Reliability
If DGA is used for monitoring, then accumulated gas build-up can be detected, but objective immediate temperature indication is not provided
Solution Approach 1:
The patent employs detectable material that changes its optical properties (color or fluorescence) when released by the rupture disk at threshold temperature. This provides objective, immediate visual indication of overheating status, resolving the contradiction by delivering both reliable objective monitoring and complete temperature status information without loss
3Productivity
If conventional monitoring methods are used, then accumulated data can be analyzed, but immediate maintenance triggering is not enabled
Solution Approach 1:
The patent employs a rupture disk pre-calibrated to burst at a specific threshold temperature corresponding to imminent failure conditions. This preliminary action enables immediate triggering of maintenance activities precisely when needed, resolving the contradiction by providing both high maintenance efficiency and zero time loss in detecting threshold temperature
Solution Approach 2:
The patent creates an immediate feedback loop where the rupture disk burst provides real-time information about threshold temperature achievement. This feedback mechanism enables instant maintenance triggering, resolving the contradiction by achieving both high productivity through timely maintenance and minimal time loss in detection

AI summary
A burst temperature indicator system for determining when an electrical contact or other component reaches a predetermined temperature. In operation, a trace material may disperse into a surrounding environment, and be detected, when the electrical component reaches a predetermined threshold temperature. One or more foil barriers may be ruptured or broken by temperature-induced gas pressure. According to another aspect of this disclosure, a rupture disk may be burst at a predetermined temperature to generate, or enable emission of, a light signal. According to another aspect, a rupture disk device acts as, or is associated with, an engine to drive one or more electro-mechanical and/or acoustic devices to signal the occurrence of a predetermined temperature.
