Specific meanings of the above terms in the embodiments of the present application can be understood in specific cases by those of ordinary skill in the art.
Referring to fig. 1, an automatic oil filter pipe type oil level indicator 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 a communicating cavity 21 is arranged in the connecting box; the upper end of the communicating 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 oil pressing bag 3 is arranged above the oil cavity 11; the port position 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 the bottom of the filter 6 is provided with a filtering oil outlet 61; an oil drain valve 62 for controlling the opening and closing of the oil filtering port 61 is arranged on the oil filtering port 61.
Specifically, when the oil level in the oil cavity 11 is too high and is submerged in the main oil pressing bag 3, the insulating oil flows towards the connecting box 2 under the pressure of the main oil pressing bag 3, so that the oil level in the glass tube 7 is moved to be 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 is connected to seal the port of the connecting pipe 5 in a conventional state, so that oil in the glass tube 7 can be separated from oil in the oil cavity 11, and the oil in the glass tube 7 is prevented from influencing the oil in the oil cavity 11 after being degraded due to illumination and other reasons; meanwhile, when the oil pressure in the oil chamber 11 rises, the pressure of the connecting oil bag 4 is separated from the connecting pipe 5, so that the indication of the floating ball 8 to the oil level can not be influenced. And, through setting up filter 6, can in time discharge the oil of deterioration in the glass pipe 7, avoid the oil of deterioration to influence the performance of transformer.
Further, the filter 6 comprises a three-port pipe 63, a two-port pipe 64, a first tee pipe 65 and a second tee pipe 66; three pipe orifices of the first three-way 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 second ends of the glass pipe 7 and 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; bypass valves 67 for controlling the opening and closing of the pipelines are arranged on the three-port pipe 63 and the two-port pipe 64.
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 tube 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 can be opened, the insulating oil flows through the two-port pipe 64 to the glass tube 7, the three-port pipe 63 can be detached and cleaned, and the quality of the insulating oil is easy to maintain and kept.
Furthermore, the organic filter screen and the oil filter paper which are overlapped are arranged inside the filtering oil outlet, the organic filter screen can be cleaned and reused, and the overlapped oil filter paper is beneficial to solidification of filtered substances.
Further, the main oil tank 1 is provided with a release valve, and the release valve can be opened to reduce the air pressure in the oil cavity 11 when the oil level rises or the main pressure oil bag 3 expands.
Further, an oil inlet is formed in the main oil tank 1, and the flow flowing out through the filter 6 can be supplemented.
Although the present invention has been described in detail with reference to examples, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention.
