El Niño "heat" test: Power grid faces unprecedented thermal pressure

As El Niño events become more frequent, extreme high-temperature weather is shifting from "occasional" to "normal", driving the power load of the whole society to repeatedly reach new highs and exposing transmission lines to severe overheating risks. The sharp increase in load causes the conductor temperature to rise rapidly, while key nodes such as connecting fittings and clamps, due to long-term operation, have problems such as loose joints, oxidation and corrosion. Under high temperatures, the resistance increases, creating a vicious cycle—once the temperature exceeds the safety threshold, it will accelerate aging at the mildest, and cause wire breakage, melting or even fire at the worst. Traditional manual inspection relies on infrared thermal imagers to inspect each tower one by one, which has a long cycle and narrow coverage, making it almost impossible to capture sudden temperature rises between two inspections. Transmission lines urgently need a "online thermometer" that works 24 hours a day to eliminate problems at the initial stage of "fever".

TLKS-PMG-TP: Install a "smart thermometer" for high-voltage lines

TLKS-PMG-TP Transmission line strain clamp temperature measuring device is developed for heat prevention and control of high-voltage transmission lines, and is mainly used for all-weather temperature collection and monitoring of key parts such as conductors, connecting fittings and clamps. Relying on contact digital temperature measurement and wireless transmission technology, the device can real-time capture abnormal temperature rises caused by overload, loose joints and aging, and automatically give early warnings. It completely solves the pain points of lag and incomplete coverage of manual inspection, and is a core intelligent operation and maintenance device to ensure the stable operation of high-voltage lines.

Working principle

TLKS-PMG-TP Transmission line strain clamp temperature measuring device adopts a three-level monitoring architecture of front-end sensor collection, wireless transmission and background analysis. High-precision temperature sensors deployed on line conductors and clamps collect real-time surface temperature data, transmit it to the terminal host for summary processing through wireless communication, and then upload it to the monitoring center platform via communication network. The system intelligently judges the operating status according to the preset threshold, and triggers an early warning immediately once an abnormal temperature rise is detected, helping operation and maintenance personnel accurately locate the fault point and carry out maintenance and rectification in time.

Core functions

⚡ Equipotential anti-interference design: The equipotential structure design of the shell and the conductor effectively resists high-voltage electromagnetic interference and ensures accurate and stable data.
