Solution Overview
Problem
Existing systems struggle to efficiently determine the location of abnormalities, such as short-circuiting or disconnection, on complex thermal lines in power feeders due to their intricate wiring layouts, which hinders operator efficiency in addressing these issues.
Innovation Solution
An abnormality locating system that includes a display device, controller, and storage for map data, which displays the estimated position of abnormalities on a thermal line's wiring layout, using a distance information obtainer and abnormality site display processor to facilitate easy identification of the abnormality site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the thermal line is wired along complex paths to adapt to the movement path, then the power feeder can follow the movement path flexibly, but the operator has difficulty determining the short-circuit point on the wiring layout
Solution Approach 1:
The patent creates a visual copy or map representation of the thermal line wiring layout on a display device. This map shows the complex paths in a simplified, visual format that operators can easily interpret, allowing them to locate abnormalities without physically tracing the complex wiring paths.
Solution Approach 2:
The patent transforms the three-dimensional complex wiring paths into a two-dimensional map representation on a display device. This dimensional transformation allows operators to view and understand the complex layout from a top-down perspective, making location determination much easier.
2Measurement precision
If the operator manually traces the thermal line path to determine the short-circuit point, then the position can be identified, but the work efficiency is reduced due to the complex wiring layout
Solution Approach 1:
The system creates a digital map copy of the thermal line layout and displays it on a display device. This visual copy allows operators to quickly identify abnormality locations without manual tracing, maintaining accurate location determination while significantly improving work efficiency.
Solution Approach 2:
The patent replaces the manual mechanical process of tracing physical wiring paths with an automated electronic system that displays the wiring layout and abnormality positions on a display device, eliminating the need for operators to physically trace complex paths.
3Ease of operation
If the system provides detailed map data and visual display of thermal line positions, then the operator can easily locate abnormalities, but the device complexity increases
Solution Approach 1:
The controller serves multiple functions: it manages the thermal line monitoring, processes location data, and controls the display device to show the wiring layout and abnormality positions. This multi-functionality reduces the need for separate dedicated components, thereby limiting device complexity while maintaining ease of operation.

AI summary
An abnormality locating system includes a display device, a controller, and a storage storing map data of a power feeder. The controller includes a distance information obtainer that obtains distance information indicating a distance from a power supply to a location of the abnormality, and an abnormality site display processor. The abnormality site display processor performs an abnormality site estimation process of estimating a location of an abnormality site based on the distance information, the abnormality site is a site of the abnormality of the thermal line, and a display process of causing the display device to display a map indicating a position of the thermal line based on the map data and to display, on the map, an estimated position of the abnormality site estimated through the abnormality site estimation process.
