Zusammenfassung:The invention belongs to the technical field of electrical equipment fault diagnosis, and particularly relates to a closed oil-filled electrical equipment oil level detection temperature correction system and method, and the system comprises an ultrasonic probe, a transducer, an emission control and receiving circuit, and a controller. The controller is used for controlling the transmitting control and receiving circuit to generate ultrasonic waves, receiving echoes received by the transmitting control and receiving circuit and carrying out temperature correction on the propagation speed of the ultrasonic waves in the insulating oil so as to obtain an accurate oil level; the emission control and receiving circuit is used for generating corresponding ultrasonic waves under the control of the controller; the transducer is used for converting ultrasonic waves generated by the emission control and receiving circuit, transmitting the ultrasonic waves to the ultrasonic probe and transmitting echoes collected by the
