Transmission line on-line monitoring system

1. Product overview of transmission line online monitoring system

The transmission line online monitoring system can dynamically display the real-time weather information around each substation and help the dispatcher to carry out comprehensive weather analysis . There are many problems such as inspection blind spots. The transmission line online monitoring system FT-DQX6 is mainly developed and produced for the local meteorological environment monitoring of the transmission line corridor. It is mainly installed on the power tower. The installation monitoring position can be installed according to customer requirements. The system can monitor the wind speed and wind direction in the line area in real time , temperature, humidity, air pressure, rainfall and other meteorological parameters, the monitored parameters can be wirelessly transmitted to the monitoring center through GPRS/fiber optics, analyzed in real time, and the warning information is sent to the mobile phone of the setting personnel.

Since the overhead transmission lines in our country have been in the wild for a long time, they are often affected by external environmental factors. Strong winds, heavy rains, ice and snow disasters are unavoidable. These external factors will cause short circuits, trips, and downed poles and towers in the line, which will greatly affect the power supply of the grid and the electricity consumption of residents. Therefore, the Electric Power Bureau attaches great importance to the safety management and construction of transmission lines.

2. Product Features of Transmission Line Online Monitoring System
