Temperature measuring device for strain clamp of transmission line

model:DX-WPS100-CW

1、 Demand analysis

At present, there is a serious shortage of electric power in China. The traditional capacity increasing technologies such as using heat-resistant conductors and improving the cross-sectional area of conductors have problems such as long construction period, difficult acquisition of transmission corridors, and high cost. Starting from the relationship between the conductor temperature and the current carrying capacity of the transmission line, the online temperature monitoring device for the transmission line clamp is proposed based on the theoretical model of dynamic capacity increase of the transmission line based on the operating temperature of the conductor and the clamp. The temperature measuring device adopts the electric field energy collection technology combined with the battery power supply, which solves the problem of difficult power supply for the temperature measuring device, The wire temperature hosts can support the access of multi probe temperature data, provide decision-making basis for the capacity increase of transmission lines, and ensure the stable operation of lines.


2、 Working principle

The online temperature monitoring device of transmission line clamp adopts the Internet of Things technology to monitor the working temperature of the tension tower joint, so as to prevent the tension clamp from being damaged by thermal stress due to factors such as construction technology, material, overload and loose connecting plate bolts, which will eventually lead to accidents. The host computer sends the temperature data collected by the clamp temperature sensor to the monitoring center through the 4G/5G/WIFI wireless network after digitization and compression coding, decodes the data signal in the monitoring center, and visually displays the wire temperature data on the screen in the form of figures and charts. When the temperature exceeds the set threshold, the alarm will be started immediately, and the management personnel will notify the maintenance personnel to deal with it in time to ensure the stable operation of the line.
