Description
Technical field
The invention belongs to power safety technique field, more particularly to a kind of dress that draws oil sample for main transformer on-load switch
Put.
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, close main transformer enter, the valve of oil exit pipe, then the series of steps such as carry out dismounting pipe, draw oil sample, depositing
It is cumbersome in process, the deficiencies of longevity of service.The presently most used method that draws oil sample, 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 adpting flange position cushion rubber, aging cracking easily occurs, causes leakage of oil.
The content of the invention
The present invention is the above-mentioned at least one technological deficiency of solution, there is provided a kind of to take oil for main transformer on-load switch
Sampling device.The device need not carry out the dismounting of connecting leg, and opening valve can just be drawn oil sample, and reach and do not waste loaded switch oil
Purpose, solve the problems, such as cushion rubber aging cracking, do not occur oil leak, saving is drawn oil sample the time, improves operating efficiency.
The technical scheme is that：A kind of oil sealed sampling device for main transformer on-load switch, the wherein device are provided with peace
Dress portion, connecting portion, the center of installation portion is embedded in connecting portion, the center of connecting portion is provided with the first perforation, if installation portion is provided with
Dry fixing hole, the second perforation is provided between the outer wall and inwall of installation portion, the second perforation connects with the first perforation, outside installation portion
Wall is provided with and takes fuel tap, takes fuel tap to be perforated with second and connects, the device is by taking fuel tap to be drawn oil sample.
The device is fixed on main transformer on-load switch oil extraction pipe flange by the fixing hole of installation 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 installation 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, fixing 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 provided between connecting portion and installation portion.Sealing ring is installed provided with o-ring groove, solved
, no longer there is oil leak in cushion rubber aging cracking problem.
Further, the second perforation connects with the first perforated vertical in the axial direction, is advantageous to quickly be drawn oil sample, and improves effect
Rate.
The beneficial effects of the invention are as follows：
（1）The device need not carry out the dismounting of connecting leg, open valve with regard to that can be drawn oil sample, and 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 operating efficiency.
