Abstract

The invention relates to a high voltage transmission line conductor temperature monitoring technology, in particular to an online high voltage transmission line conductor temperature monitoring system based on a GPRS network. The online high voltage transmission line conductor temperature monitoring system solves the problems that an existing high voltage transmission line conductor temperature monitoring system is unstable in operation, poor in operation reliability, prone to breaking during operation and high in operation maintenance cost. The online high voltage transmission line conductor temperature monitoring system based on the GPRS network comprises a data collection part, a data transmission part and a data processing part. The data collection part comprises a surface acoustic wave transducer, a polymer lithium iron battery, a solar cell panel, a charging and discharging controller and a temperature monitoring terminal. The data transmission part comprises a GPRS base station, an RS-485 bus, a coaxial cable and an Ethernet switch. The data processing part comprises a master control terminal, a local host and a remote SCADA host. The online high voltage transmission line conductor temperature monitoring system is applicable to high voltage transmission lines.

Description

technical field [0001] The invention relates to a technology for monitoring the temperature of a conductor of a high-voltage transmission line, in particular to an online monitoring system for the temperature of a conductor of a high-voltage transmission line based on a GPRS network. Background technique [0002] During the daily operation of high-voltage transmission lines, it is easy to cause the temperature of the wire to be too high due to various factors such as load overload, ambient temperature, wind cooling, and solar radiation. Once the temperature of the conductor of the high-voltage transmission line is too high, it will directly affect the transmission power of the high-voltage transmission line on the one hand, and on the other hand, it will directly affect the life of the conductor of the high-voltage transmission line. Therefore, in order to ensure the transmission power and conductor life of the high-voltage transmission line, it is necessary to monitor the t...
