Example Embodiment
[0038] The present invention will be further described in detail below in conjunction with specific embodiments, which are for explanation rather than limitation of the present invention.
[0039] The present invention is an oil level monitoring system of an oil-immersed transformer oil storage system, such as figure 1 As shown, it includes a pressure sensor 1 set on a transformer, and a monitoring terminal 2 connected to the output end of the pressure sensor 1. The monitoring terminal 2 is used to convert the pressure signal collected by the pressure sensor 1 into an oil level signal, and simultaneously The oil level signal and the pressure signal are monitored. When the oil level signal or the pressure signal exceeds a safe value, the monitoring terminal 2 issues an alarm.
[0040] Preferably, the output end of the monitoring terminal 2 is connected to the host computer 4 for recording and analyzing the oil level signal output by the monitoring terminal 2; the connection line bet...
