Temperature measuring device for strain clamps of transmission line conductors

In today's era where smart grids and the safe operation of transmission lines are receiving increasing attention, precise control of line load and early warning of overheating risks have become core challenges for operation and maintenance work. Traditional manual inspection or regular measurement methods struggle to achieve all-weather, real-time, continuous temperature monitoring, especially in key scenarios such as dynamic capacity increase, ice melting, and peak load periods, where there are data lag and blind spot risks.

Now, there is a smarter solution for all of this. We are proud to launch the new generation of Transmission Line Clamp and Conductor Temperature Online Monitoring Device (TLKS-PMG-TP) — an online monitoring device based on the dynamic capacity increase theoretical model of transmission lines using conductor temperature, designed specifically for real-time, precise, remote monitoring of clamp and conductor temperatures. It deeply integrates front-end sensing, wireless communication, and intelligent analysis, keeping line temperature status fully under control, and helping grid operation shift from "experience-driven" to "data-driven".

Core Functions: Panoratic Perception, Intelligent Interconnection

TLKS-PMG-TP is not just a temperature measurement device, but also a miniature monitoring station integrating environmental perception and data intelligence:

1. Precise Multi-dimensional Temperature Measurement
• Adopts contact platinum resistance temperature measurement to accurately perceive the temperature of conductor surfaces and hardware (clamps), with a measurement range of -40℃~120℃ and an accuracy of ±0.5℃.
• Supports up to 24 temperature data accesses simultaneously, fully covering key heating points.
• Equipped with data rationality check function, automatically eliminating interference to ensure data authenticity and reliability.
2. Reliable and Stable Operation
• Equal potential design: The device housing has the same potential as the conductor, fundamentally resisting high voltage and electromagnetic interference, ensuring long-term stable operation.
• Strong environmental adaptability: Operating temperature covers -40℃~70℃, withstands large current impacts, and is not afraid of harsh outdoor environments.
• Long-lasting self-power supply: Adopts a solar + battery power supply mode, achieving energy self-sufficiency and continuous operation.
3. Intelligent Analysis and Remote Operation and Maintenance
• Deep data processing: Has a primary calculation function, converting raw data into intuitive temperature status values, and cyclically storing at least 30 days of historical data.
• Remote intelligent management and control: Supports identity authentication, remote program updates, parameter configuration and debugging, greatly reducing on-site maintenance costs and frequency.
• Advanced security encryption: Built-in security chip, encrypted data transmission, can safely access provincial company internal network platforms and PMS systems.
4. Optional Expansion Functions (Configurable on Demand)
• Micro-meteorological monitoring: Integrates environmental temperature and humidity, air pressure, wind speed, and wind direction sensors, providing precise environmental parameters for dynamic capacity increase.
• Visual image monitoring: Equipped with a camera, real-time viewing of tower surrounding images, assisting in judging ice coverage, external damage, wildfires and other conditions.

Technical Parameters: Professional Performance, Trustworthy

Core Application Scenarios: Precise Deployment, Creating Value

TLKS-PMG-TP is a tool to improve the intelligent level of line operation and maintenance and ensure the safe and economic operation of the power grid, especially suitable for:

• Dynamic capacity increase of transmission lines: Real-time monitoring of conductor temperature, providing core data basis for tapping line transmission potential and scientifically implementing dynamic capacity increase.
• Overheating early warning at key nodes: Continuous monitoring of easily heated conductor joints, clamps, jumpers and other hardware, preventing overheating and burning accidents caused by increased contact resistance.
• DC ice melting process monitoring: When implementing DC ice melting on winter iced lines, accurately monitor conductor temperature to prevent conductor damage due to excessive temperature during ice melting.
• Heavy load line monitoring: Focus on monitoring lines with heavy load or under "N-1" operation mode, ensuring operating temperature is within a safe range.
• Special section operation and maintenance: Applied to key sections such as large spans, important cross-overs, and urban cable joints.

ChoosingTLKS-PMG-TP means choosing:

• Safety upgrade: Turn passive response into active early warning, significantly reducing the risk of safety accidents such as wire breakage and tripping caused by overheating.
• Benefit improvement: Through dynamic capacity increase, fully release the transmission capacity of existing lines while ensuring safety, delaying or reducing infrastructure investment.
• Operation and maintenance efficiency improvement: Realize remote real-time monitoring and intelligent diagnosis, reducing unnecessary on-site inspections, lowering operation and maintenance costs and personnel safety risks.
• Decision support: Accumulate long-term, continuous, authentic temperature operation data, providing scientific basis for line condition evaluation, life assessment and grid planning.

Let every degree of change be fully under control.
