The invention discloses an insulator fault monitoring system and an insulator fault intelligent operation and maintenance platform. The problems of blindness, great time consumption , great workload and inspection missing of artificial insulator fault general checking are solved, so that insulator faults can be timely found and repaired. The insulator fault monitoring system comprises a leakage current detection wireless device and a fault management terminal, wherein the leakage current detection wireless device has a self electricity generation function and detects insulators in real time toobtain detection information of the insulators, wherein the detection information includes leakage current original data or fault data; the leakage current detection wireless device sends the detection information to the fault management terminal; and the fault management terminal generates fault warning information according to the detection information.
