The "dirt" that adheres to the grid insulators includes but is not limited to dirt, dust, industrial dust such as coal ash, animal feces, salt spray, all of which are visible "flashover threats", and some areas with high humidity and 70% rainfall may also harbor algae/mosses, etc. etc.
Different regions and insulator equipment surface dirt adherents have different locations, if you do not clean or replace the insulator equipment in time, it is likely to cause hidden electrical damage, such as partial discharge, potential distribution distortion, insulation resistance drop; and may even lead to relay protection error, neighboring equipment overload, multiple lines at the same time tripped the risk of chain failures.
The traditional insulator dirt flash detection method requires a particularly long period of time, timely detection of insulator dirt degree, transmission line anti-fouling flash has its own "intelligent sentinel" - Shenzhen Dingxin Wisdom Technology's insulator dirtiness monitoring device. Monitoring device (model DX-WPS100-WH), the device mainly uses fiber optic sensing, can meet the high precision real-time barrier-free collection of insulator salt density, ash density, air temperature, relative humidity and other elements of the detection needs (support for controlled collection and interval collection), the data through the 4G/GSM/CDMA/GPRS and other adaptive field communication network The data is transmitted back to the monitoring center, and the software system of the monitoring center stores, calculates and analyzes the data, which helps the electric power personnel to quickly grasp the dirtiness data of insulator strings in the monitoring area and the trend of development, and thus reasonably arrange the corresponding maintenance work.
