AI Technical Summary

Technical Problem

Existing technologies cannot accurately calculate the effect of temperature when detecting humidity in a dry air ring main unit. Traditional methods are cumbersome to operate and damage the environment inside the air chamber, resulting in inaccurate test results and large errors.

Method used

A ring main unit air temperature and humidity test method based on dynamic humidity control is adopted. The high and low temperature test chamber and the permeation unit and drying unit are used to automatically adjust the temperature and humidity of the air chamber. The humidity is precisely adjusted through the permeation tube and desiccant, and a dedicated temperature-humidity conversion table is generated.

Benefits of technology

It enables accurate acquisition of humidity data without disrupting the air chamber environment, generating a dedicated temperature-humidity conversion table suitable for dry air ring network cabinets, improving the representativeness and reliability of test data, reducing human error, and supporting 24-hour continuous testing.
