Description

Technical Field

[0001] This invention relates to a testing device and method for electrical control cabinet circuits, belonging to the technical field of testing equipment. Background Technology

[0002] Currently, electrical control cabinets, as core equipment for industrial automation and power distribution, are experiencing increasing complexity and density of internal wiring. Traditional wiring testing methods mainly rely on electricians using various discrete instruments such as multimeters, megohmmeters, and clamp meters to perform segmented and itemized measurements. Traditional wiring testing tools are numerous, inconvenient to carry and switch, and have low testing efficiency. Furthermore, the testing process is highly dependent on manual interpretation and experience analysis, which is not only time-consuming for tracing wiring routes and judging hidden faults, but also prone to misjudgment or omission. Traditional line testing tools lack the ability to systematically record and analyze test data, making it impossible to conduct trend assessments and early warnings of the line's health status. They often only investigate after a fault occurs, posing a threat to production safety. Summary of the Invention
