Study on Reliability System of A Monitoring Device for Power Transmission and Transformation based on Transportation and Inspection IOT

With all-round changes brought by the Internet in technology, thinking, concept, and mode of the power grid, the production, work, and operation mode of power grid have also undergone brand-new intelligent ecological changes. Mobile informatization has gradually become the “standard configuration” for power grid informatization construction. Given the characteristics of transportation inspection and future development requirements, it is necessary to deeply analyze and apply the integration of “Internet + grid transportation inspection”, comprehensively change the traditional transportation inspection management mode and working mode, and build an intelligent mobile Internet system for transportation inspection. At present, the reliability and effectiveness of IOT power transmission and transformation devices are not optimistic. With a large number of device faults and false alarms, long-term operation reliability assessment of the devices of various manufacturers lack effective means and method, and the device availability rate is generally low [1]. The alarm accuracy of the device is difficult to judge, and there is a large amount of invalid data. The data validity cannot be judged in the master station. Monitoring devices of various manufacturers lack automatic monitoring, which brings great trouble to the application of line monitoring device and monitoring information in line operation and maintenance. The reliability system of monitoring device for power transmission and transformation based on transportation and inspection IOT uses Internet area to form integrated, grid and intelligent comprehensive monitoring, diagnosis and service management of reliability and availability of power transmission and transformation state detection device. In this way, it is possible to quickly and conveniently help operation and management personnel adjust the device operation in time, conduct monitoring, alarm analysis and processing, and preventive device maintenance of the power transmission and transformation equipment state monitoring device anytime, anywhere, which provides strong technical support for increasing device availability and enhancing professional support for inspection and control. By business-driven integrated development, it is possible to achieve the goals of improving efficiency, reducing costs, improving services, and creating value.
