Abstract
At present, UHV surge arresters have a large number of sections and complex structures. The existing live detection and online monitoring technologies can no longer effectively determine the problem of deterioration of the internal resistance of the arrester. This paper studies the structure, power supply, temperature and humidity measurement and wireless transmission methods of measuring probes that can be placed in the arrester for a long time. By measuring the temperature, humidity and current data of each node, and sending it to the background wirelessly, it is more effective to judge the UHV Internal defects of the arrester. The method of internally measuring the temperature and humidity of the arrester node can improve the diagnostic ability of the internal defect and defect location of the UHV arrester, and realize the effective identification and location of the internal fault of the UHV arrester.
