On-line transformer oil level monitoring system

The utility model discloses an on-line transformer oil level monitoring system which comprises a transformer oil storage cabinet, wherein an oil level sensor and a temperature sensor are arranged in the transformer oil storage cabinet and are connected with an intelligent oil level device through a control cable; the intelligent oil level device is connected with a database server through an RS485 communication network; the database server is connected with a system terminal through an Ethernet. The on-line transformer oil level monitoring system realizes real-time digital monitoring on a transformer oil level; under consideration of a temperature influence factor, oil level information can be accurately monitored, and a transformer oil leakage fault can be effectively found; furthermore, remote monitoring on real-time oil level detection information and an oil level fault signal is also realized.
