Background technology
Transforming plant main transformer loaded switch draws oil sample, and is after the frequent bringing onto load switching of periodic monitoring main transformer on-load switch, there is load
Whether the indices of switch luboil cleanness close a major tasks of symbol standard.Must first it be closed when being drawn oil sample
Load switch oil-filtering apparatus power supply, closes main transformer into the valve of, oil exit pipe, then the series of steps such as carries out dismounting pipe, draws oil sample, and deposits
It is cumbersome in process, the deficiencies of longevity of service.The presently most used method that draws oil sample, is needed main transformer oil extraction tube valve and filter
The soft connecting leg of oily device is removed, during can slattern in soft connecting leg loaded switch oil, repeatedly drawing oil sample to have reduced
Load switch oil level, moreover, in demolishing process connecting flange position cushion rubber, aging cracking easily occurs, causes leakage of oil.
Utility model content
The utility model is solves above-mentioned at least one technological deficiency, there is provided a kind of for main transformer on-load switch
Oil sealed sampling device.The device need not carry out the dismounting of connecting leg, and opening valve can just draw oil sample, and reach and do not wasted load and open
The purpose of oil is closed, solves the problems, such as cushion rubber aging cracking, oil leak does not occur, saving is drawn oil sample the time, improves work efficiency.
The technical solution of the utility model is：A kind of oil sealed sampling device for main transformer on-load switch, the wherein device are set
There are mounting portion, connecting portion, the center of mounting portion is embedded in connecting portion, the center of connecting portion is equipped with the first perforation, and mounting portion is set
There are some mounting holes, the second perforation is equipped between the outer wall and inner wall of mounting portion, the second perforation is connected with the first perforation, mounting portion
Outer wall be equipped with take fuel tap, take fuel tap with second perforation connect, the device is by taking fuel tap to draw oil sample.
The device is fixed on main transformer on-load switch oil extraction pipe flange by the mounting hole of mounting portion and is flexible coupling with oil-filtering apparatus
Between pipe flange, the first perforation of oil exit pipe and connecting portion is fitting to connection, and the first perforation connect with the second perforation, second perforate and
Fuel tap is taken to connect, can be by taking fuel tap to draw oil sample main transformer on-load switch oil exit pipe.
Further, connecting portion forms the oil sealed sampling device of circular ring type structure with mounting portion.Circular ring type structure has load with main transformer
Switch oil exit pipe flange is adapted with oil-filtering apparatus hose connector flange, and connection is more firm.
Further, mounting hole annular array centered on the center of circle of annulus is set, and is completely embedded the device firm, will not
Generation oil leak.
Further, o-ring groove is equipped between connecting portion and mounting portion.Sealing ring is installed equipped with o-ring groove, is solved
, no longer there is oil leak in cushion rubber aging cracking problem.
Further, the second perforation is connected with the first perforated vertical in the axial direction, is conducive to quickly draw oil sample, and improves effect
Rate.
The beneficial effects of the utility model are：
（1）The device need not carry out the dismounting of connecting leg, open valve with regard to that can draw oil sample, do not waste loaded switch
Oil.
（2）Cushion rubber aging cracking problem no longer occurs, and oil leak does not occur.
（3）Saving is drawn oil sample the time, improves work efficiency.
