Ubiquitous power Internet of Things surge monitoring and early warning device

Abstract

The invention relates to a ubiquitous power Internet of Things surge monitoring and early warning device which is installed near high-voltage power distribution equipment with a lightning arrester. The device comprises a case and a solar panel. A circuit board and a wireless communication module are installed in the case. The circuit board is provided with an MCU minimum system, a zero-flux mutualinductor, a Rogowski coil and a serial port communication module. A lightning protection grounding wire of the lightning protection device is connected with an upper induction coil and a lower induction coil in series, and the upper induction coil is connected with the input side of the Rogowski coil. The lower induction coil is connected with the input side of the zero-flux transformer. The MCUminimum system on the circuit board is in bidirectional connection with the serial port communication module, and is connected with the zero-flux mutual inductor and the Rogowski coil to acquire signals. The solar panel is used for supplying power to each module and device in the case through the MCU minimum system. The serial port communication module is in bidirectional connection with the wireless communication module. According to the ubiquitous power Internet of Things surge monitoring and early warning device, performance monitoring is carried out on the lightning arrester device, and safe operation of an electric power system is guaranteed.

[0002] In recent years, in order to reduce the circuit breaker action caused by the overvoltage caused by lightning strikes on outdoor transmission lines, MOA arresters for high-voltage transmission lines have played a huge role and have been widely used. The performance of MOA arresters directly affects the safe operation of power systems. ;Because the MOA arrester will gradually age under the action of high power frequency and high voltage for a long time, breakdown damage may occur during operation, and the protection characteristics will decline, so it will have extremely serious consequences. In order to ensure the safe operation of the MOA arrester, MOA must be Surge arresters are strictly monitored

However, because many high-voltage power grids are set in remote mountainous areas, and the arrester monitoring devices are installed at the height of the tower, it is difficult to read the meter and overhaul the arrester parameters; the existing method is to use regular rotation arresters, and once a year In the standard maintenance of the standard maintenance, the pole tower is checked, the lightning arrester and the grounding device are cleaned; this method of replacing the lightning arrester and cleaning is expensive, labor-intensive, and needs to apply for a long period of power outage, which is not conducive to the economical and stable operation of the transmission line.
