Solution Overview
Problem
Current switch-gear and control-gear systems for medium or high voltage rely on manual or fixed sensors for inspection and maintenance, which limits the scope of technical diagnostics and cannot initiate automatic solutions for maintenance issues.
Innovation Solution
Integration of a robotic system with a camera and image recognition system for unmanned operation and maintenance, enabling detailed visual data collection and automated analysis to detect faults and malfunctions, with non-contact sensors for visual and thermographic inspections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection or fixed sensors are used for switch-gear monitoring, then the system structure remains simple, but the inspection scope is limited and cannot detect faults effectively
Solution Approach 1:
The patent replaces manual inspection and fixed sensors with a robotic system that can move freely within the switch-gear enclosure. The robot carries cameras and sensors to actively inspect components, substituting mechanical inspection methods with automated robotic exploration to achieve comprehensive coverage without proportionally increasing system complexity
Solution Approach 2:
The inspection system transitions from static fixed sensors to a dynamic robotic platform that can change position and orientation. The robot moves to different locations within the switch-gear to inspect various components, enabling adaptive inspection scope that adjusts to the actual spatial distribution of equipment
2Reliability
If periodic shutdown and testing are performed for maintenance, then thorough inspection can be conducted, but system availability and productivity are reduced
Solution Approach 1:
The robotic inspection system enables continuous monitoring of switch-gear components without requiring shutdowns. The robot can inspect energized equipment using non-contact sensors and visual systems, maintaining system operation while performing maintenance functions, thus eliminating interruptions to productivity
Solution Approach 2:
The robot acts as an intermediary between the operational switch-gear and the maintenance function. It introduces advanced sensing capabilities (thermal cameras, visual systems) that can assess component condition during operation, serving as a mediator that enables maintenance without requiring system shutdown
3Loss of information
If fixed sensors are used for technical diagnosis, then the system structure is simple, but the ability to detect and respond to faults is insufficient
Solution Approach 1:
The robotic system integrates multiple sensing functions into a single platform, including visual cameras, thermal sensors, and other detection devices. This multi-functional robot can perform various inspection tasks (visual inspection, thermal monitoring, spatial mapping) that would otherwise require multiple separate sensor systems, reducing information loss while managing complexity through integration
4Productivity
If manual maintenance operations are performed, then the required equipment is simple, but the speed and effectiveness of maintenance actions are limited
Solution Approach 1:
The robotic system performs maintenance functions autonomously without requiring human operators to physically access the switch-gear. The robot navigates, inspects, and can execute maintenance actions automatically based on sensor data and image recognition, enabling self-service capability that increases maintenance speed while the complexity is contained within the automated system
