Terminal system of high-voltage cable service life analysis model based on harmonic monitoring

The invention discloses a terminal system of a high-voltage cable life analysis model based on harmonic monitoring, which relates to the technical field of high-voltage cable life analysis and comprises a data acquisition module, a data processing module, a data analysis module and an evaluation module. The data acquisition module is used for detecting a current harmonic signal of each part of the cable; the data processing module is used for establishing an actual relation table and a theoretical relation table among the actual degradation degree, the aging part and the higher harmonic of the cable, and transmitting the information of the actual relation table and the theoretical relation table to the data analysis module; the data analysis module is used for correcting the theoretical relation table through the actual relation table after receiving the information of the data processing module; and the evaluation module is used for comparing, analyzing and outputting the processed data and a database to obt
