Example Embodiment
[0022] The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings:
[0023] A dual pressure sensitive correction type transformer oil level gauge, such as figure 1 As shown, including the oil level gauge body 8, the first oil level gauge body 2, the second oil level gauge body 5, the first pressure sensor 1, the second pressure sensor 4, the oil level gauge dial 3, the butterfly valve 9, the power supply and the signal Cable 6 and oil level gauge measuring circuit. The main body of the oil level gauge is a pipe with the same caliber as the oil filling and draining pipe 11 of the transformer. It is vertically arranged on the transformer and connected to the upper and lower oil filling and draining pipes through threads 10, or through flanges, etc. Connect in other ways. An oil filling and draining valve 7 is installed at the bottom of the filling and draining pipe. The first oil level gauge body and the second oi...
