Power Line Sag Monitoring and Early Warning System

I. Product Description:

The external conditions of three-span transmission lines are harsh, coupled with high-load operation, making the lines highly prone to excessive sag. Since transmission lines are overhead and often cross highways, railways, rivers, and mountains, excessive sag means the high-voltage lines are closer to the ground, which can cause short circuits, endanger power transmission safety, and even harm pedestrians, vehicles, buildings, and ships below. To address this, Shenzhen Telink Technology Co., Ltd. has developed a device that real-time measures the vertical distance between the lowest point of the sag and the ground — Power Line Sag Monitoring and Early Warning System, allowing you to always stay aware of the safe distance and control power transmission safety.

II. Working Principle:

Power Line Sag Monitoring and Early Warning System can real-time perceive the sag of the conductor. The device collects data on the conductor and its changes, and transmits them to the background monitoring center via networks such as 3G/GPRS/CDMA for analysis. If an abnormality is detected, the system will send early warning information through multiple channels to remind staff to take corresponding preventive measures.

III. Product Functions:

1. It can sense and collect the minimum distance from the conductor to the ground, the angle between the tangent direction of the conductor at the line clamp outlet and the horizontal direction, and the conductor sag, then transmit the measurement and calculation results to the condition monitoring agent or condition monitoring master station via communication network.

2. It has automatic collection function, which automatically collects the distance from the conductor to the ground, the angle between the tangent direction of the conductor at the line clamp outlet and the horizontal direction, and the conductor sag at the set time interval. The minimum collection interval should be more than 5 minutes, the maximum collection interval less than 60 minutes, and the default time interval is 30 minutes.

3. It has controlled collection function, which can respond to remote instructions and collect data in real time.

4. It has the function of collecting the voltage of the host battery and the probe battery.

5. It is equipped with a security chip, which can encrypt data and connect to the platforms of provincial companies.

V. Summary:

Through the Power Line Sag Monitoring and Early Warning System, the client can browse and observe the on-site conditions of each monitoring point in real time via the data of the management center. The background maintenance and monitoring staff can analyze and compare the conductor sag data sent from the site. If abnormal information is detected, corresponding emergency measures will be taken immediately to ensure the safe operation of high-voltage lines. The transmission line sag online monitoring system eliminates the need for manual line inspection, realizes intelligent management of power grid lines, improves the ability of lines to prevent disasters, and enhances operation and maintenance efficiency.
