10. The system for detecting and managing the internal operation parameters of the high voltage bushing based on the data analysis of claim 9, wherein the operation analysis module feeds back an abnormal operation signal or a normal operation signal to the server;

if the server receives a normal operation signal, no operation is performed;

if the server receives the abnormal operation signal, the abnormal operation signal and the product number corresponding to the high-voltage bushing are sent to the processor, the processor controls a signal module on the appointed high-voltage bushing to work according to the product number, the signal module is used for sending a detection signal to the management terminal, and the management terminal is used for detecting the appointed high-voltage bushing on the spot after receiving the detection signal.
