[0026] figure 1 Show the specific structure and principle of the present invention, by figure 1 It can be seen that this high-voltage capacitive equipment insulation online monitoring system based on GPS clock signals includes an on-site monitoring unit and a station-side control host. The on-site monitoring unit includes an on-site monitoring current unit FMU- C and the local monitoring voltage unit FMU-U that collects the voltage applied to the device, that is, the PT secondary side voltage signal. Multiple FMU-C units can be installed on a section of the bus, and only one FMU-U is required. The input of the local monitoring unit is the final screen current of the capacitive equipment under test and the voltage signal of the secondary side of the PT. The on-site monitoring unit includes a CPU, a wireless communication module, and a GPS clock receiving module, the CPU is connected to the wireless communication module and the GPS clock receiving module, and the wireless commu...
