On-line detection system and method for wire temperature of transmission line

Abstract

The system and method for on-line temperature detection of transmission line wires according to the present invention include wire vibration monitors, meteorological environment observation equipment, line monitoring equipment, and temperature monitoring terminals. The modules are all connected to the line monitoring equipment, and the line monitoring equipment is connected to the temperature monitoring terminal through the second wireless communication module. The communication ports of the temperature input module, the video acquisition module, the GPRS wireless communication module, the radio frequency module and the wired communication module are respectively connected with the communication ports of the main control circuit, and the GPRS wireless communication module is connected with the monitoring computer through the GPRS wireless network. This system can directly take power from the transmission wire, thus solving the power supply problem of long-term operation in the field; the unmanned remote measurement of the temperature of the wire saves a lot of manpower and material resources.

Description

technical field [0001] The invention relates to a remote monitoring system, in particular to an on-line temperature detection system and method for a transmission line conductor. Background technique [0002] With the rapid development of the national economy, the demand for electricity in all walks of life is increasing, and the requirements for the quality (stability, uninterrupted and accompanying services) of power supply provided by the power supply department are also getting higher and higher. The safety of power grid operation away from high-voltage transmission lines is particularly important. [0003] Transmission lines are an important part of the power system. At present, there is a serious shortage of power in my country. Traditional capacity-increasing technologies such as heat-resistant wires and increasing the cross-sectional area of ​​wires have problems such as long construction periods, difficulty in requisitioning transmission corridors, and high cost.

AI Technical Summary

Problems solved by technology

Many existing transmission lines are already under high-load operation status, and the high-load operation status puts forward strict tests on the parameters of the conductors, especially in hot summer, which will increase the temperature of the conductors, resulting in the failure of the conductors. The sag increases, making the conductor in an unsafe operating state
