On line monitoring device for transmission line tower inclination

    model：DX-WPS100-QJ

1、 Product introduction

The transmission lines are basically overhead lines. As the lines are erected in the air, they need to bear the effects of mechanical forces such as dead weight, wind, rainstorm, ice and snow, and the erosion of harmful gases such as wind sand. The operating conditions are very bad. In desert areas, high salt soil areas, goaf areas, mountain landslide areas and other unfavorable geological areas, under the action of gravity, stress and natural forces, the tower foundation is easy to deform, resulting in tower tilt, even tower collapse and disconnection, paralyzing the power supply lines, seriously affecting people's production and life, and causing huge losses. The transmission line tower tilt online monitoring device developed by our company can monitor the tower tilt in real time, understand the safety and reliability of the operating tower in a timely manner. According to the development trend of the tilt monitoring data, we can timely conduct a variety of ways of pre alarm for the tower tilt exceeding the standard, guide the overhaul and maintenance, remind the operation and maintenance personnel to strengthen the foundation, and prevent tower collapse accidents.

2、 Working principle

The host of the transmission line tower tilt online monitoring device will send the line data such as the longitudinal tilt angle, lateral tilt angle and comprehensive tilt angle of tower tilt collected by the tilt sensor to the monitoring center through 4G/5G/WIFI wireless network and power special network after digital compression and coding, and decode the convection and data signals in the monitoring center, so that the tower tilt data can be displayed on the screen directly in digital and graphic forms. The monitoring center views and observes the site conditions of each monitoring point in real time through the data monitoring client, and the maintenance and monitoring personnel analyze the tower tilt data sent from the site. In case of abnormal early warning information, they immediately make corresponding emergency treatment to ensure the safe operation of the high-voltage line.
