The specific meaning of the terms in the embodiments of the present application will be understood by those of ordinary skill in the art in a specific context.
Referring to fig. 1, an automatic oil filtering pipe type oil level gauge provided in an embodiment of the present application includes: the device comprises a main oil tank 1, a connecting tank 2, a main pressure oil bag 3, a connecting oil bag 4, a connecting pipe 5, a filter 6, a glass pipe 7 and a floating ball 8; an oil cavity 11 for storing insulating oil is arranged in the main oil tank 1; the connecting box 2 is arranged below the main oil tank 1 and is internally provided with a communication cavity 21; the upper end of the communication cavity 21 is communicated with the oil cavity 11, and the lower end is communicated with the first end of the connecting pipe 5; the main pressure oil bag 3 is arranged above the oil cavity 11; the port of the connecting oil bag 4 corresponding to the connecting pipe 5 is arranged in the communicating cavity 21; the glass tube 7 is vertically arranged; the floating ball 8 is arranged in the glass tube 7; the filter 6 is respectively communicated with the second end of the connecting pipe 5 and the glass pipe 7, and a filtering oil outlet 61 is arranged at the bottom of the filter 6; the filter oil outlet 61 is provided with an oil drain valve 62 for controlling the opening and closing of the filter oil outlet 61.
Specifically, when the oil level in the oil cavity 11 is too high and the main pressure oil bag 3 is flooded, the insulating oil flows towards the direction of the connecting box 2 by the pressure of the main pressure oil bag 3, so that the oil level in the movable glass tube 7 is increased; the staff can observe the oil level in the main oil tank 1 by observing the floating ball in the glass tube 7. By arranging the connecting box 2 and the connecting oil bag 4, the connecting oil bag 4 seals the port of the connecting pipe 5 in a normal state, so that oil in the glass pipe 7 can be isolated from oil in the oil cavity 11, and the oil in the glass pipe 7 is prevented from influencing the oil in the oil cavity 11 after being deteriorated due to illumination and the like; meanwhile, when the oil pressure in the oil cavity 11 is increased, the pressure of the connecting oil bag 4 is separated from the connecting pipe 5, so that the indication of the oil level by the floating ball 8 can not be influenced. Further, by providing the filter 6, the deteriorated oil in the glass tube 7 can be discharged in time, and the deteriorated oil is prevented from affecting the performance of the transformer.
Further, the filter 6 comprises a three-port pipe 63, a two-port pipe 64, a first three-way pipe 65 and a second three-way pipe 66; the three pipe orifices of the first tee pipe 65 are respectively connected with the second end of the connecting pipe 5, the first end of the three-port pipe 63 and the first end of the two-port pipe 64; the three pipe orifices of the second three-way pipe 65 are respectively connected with the glass pipe 7, the second end of the three-port pipe 63 and the second end of the two-port pipe 64; the filtering oil outlet 61 is arranged at the third end of the three-port pipe 63; the three-port pipe 63 and the two-port pipe 64 are respectively provided with a bypass valve 67 for controlling the opening and closing of the pipeline.
Specifically, in normal use, the bypass valve 67 on the two-port pipe 64 may be closed, and the insulating oil may flow through the glass pipe 7 via the three-port pipe 63. When the filter 6 needs to be replaced or filter residues on the filter 6 need to be cleaned, the bypass valve 67 on the three-port pipe 63 can be closed, the bypass valve on the two-port pipe 64 is opened, insulating oil flows through the glass pipe 7 through the two-port pipe 64, and the three-port pipe 63 can be detached and cleaned at the moment, so that the maintenance is easy, and the quality of the insulating oil is maintained.
Further, the inside of the filtering oil outlet is provided with an organic filter screen and oil filtering paper which are overlapped, the organic filter screen can be repeatedly used after being cleaned, and the overlapped oil filtering paper is helpful for solidification of filtering materials.
