CVT fault detection method and system based on transformer substation monitoring system and storage medium

The invention discloses a CVT fault detection method based on a transformer substation monitoring system. The CVT fault detection method comprises the following steps: acquiring real-time operation data of CVT equipment; judging whether the CVT equipment is abnormal or not based on the real-time operation data; and if the CVT equipment is abnormal, sending CVT alarm information to a transformer substation monitoring system. The invention further discloses a fault detection system and a storage medium. According to the fault detection method, online monitoring and fault real-time early warningof the CVT equipment are achieved, various faults possibly existing in the CVT can be found as soon as possible, faulty operation of the CVT equipment is avoided, countermeasures are taken in time toavoid equipment accidents, and safe and stable operation of a transformer substation is guaranteed. A professional fault diagnosis or data acquisition device does not need to be additionally arranged,the investment cost is ver
