The utility model provides a power transformer oil charge formula bobbin seal sampling device, includes that the sample of oil charge formula sleeve pipe connects and oil charge formula sleeve pipe sample valve, the sample of oil charge formula sleeve pipe connects including M12 1 hollow screw, outer hexagon nut, resistant oily O shape sealing washer, hollow sample mouth, external resistant oily three -way valve, oil charge formula sleeve pipe sample valve includes oil charge formula sleeve pipe sample valve, sleeve pipe sample check valve, the O of nai oil seal shape circle, is equipped with sleeve pipe sample valve sealing cap in the outward turning of oil charge formula sleeve pipe sample valve. The utility model discloses an adopt totally enclosed, with low costs, convenient to use, portable, easily on -the -spot quick sampling and maintenance. Small, dependable performance, convenient operation reduce and use the oil mass, greatly reduced intensity of labour replenish oil with the later stage sleeve pipe and work, recover the oil kind representatively, reduction chromatography's human error guarantees the normal safe operation of sheathed tube, but wide application in the totally enclosed work of drawing oil sample of electric power system transformer oil charge formula sleeve pipe.
Description
Technical field
The utility model belongs to power industry technical field, particularly a kind of transformer filling type bobbin seal sampling apparatus.
Background technology
In recent years, periodic Hidden fault detection is carried out for electric system widely used transformer filling type bushing, require should seal sampling during oil recovery sample according to standard operation, but be limited to field condition, there is the subsidiary oily sample valve of part filling type sleeve pipe, part tubular does not have hermetically sealed sample valve; Without the impact by weather, sampling instrument during hermetically sealed sample valve sampling, oil can be caused to pollute and oil sample waste, directly have influence on stratographic analysis result.Non-sealed oil sample in the past can not represent the oil sample of sleeve body completely, causes sampling element out of control, causes sample to go wrong in stratographic analysis, directly has influence on the accuracy of stratographic analysis result.
Utility model content
The purpose of this utility model will overcome the above problems exactly, a kind of power transformer filling type bobbin seal sampling apparatus is provided, volume is little, dependable performance, easy to operate, greatly reduce labour intensity and and later stage sleeve pipe makeup oil work, reduce the personal error of stratographic analysis, guarantee that the normal safe of sleeve pipe runs.
The technical solution of the utility model is achieved like this, and a kind of power transformer filling type bobbin seal sampling apparatus, is characterized in: comprise filling type sleeve pipe sample connection and filling type sleeve pipe sample valve; Filling type sleeve pipe sample connection comprises M12 × 1 cored screw, the outer-hexagonal nut on top; The center of outer-hexagonal nut has Φ 2 and samples aperture, oil resistant O-ring seals is housed between M12 × 1 cored screw and outer-hexagonal nut, the hollow sampling mouth of band screw thread is equipped with in the lower central position of hexagonal nut outside, in band screw thread hollow sampling mouth lower end, external oil resistant T-valve is housed; Filling type sleeve pipe sample valve comprise be positioned at center in " convex " font filling type sleeve pipe sample valve, be positioned at filling type sleeve pipe sample valve sleeve pipe sampling reverse checkvalve, be enclosed within filling type sleeve pipe sample valve outer ring the O of resistance to oil seal shape circle, outside filling type sleeve pipe sample valve, be installed with sleeve pipe sample valve sealing cap.
The utility model adopts hermetically sealed, and cost is low, easy to use, be easy to carry; Be easy to on-the-spot quick sampling and maintenance.Volume is little, dependable performance, easy to operate, reduce employing oil mass, greatly reduce labour intensity and and later stage sleeve pipe makeup oil work, institute's oil recovery sample is representative, reduces the personal error of stratographic analysis, guarantees that the normal safe of sleeve pipe runs; The hermetically sealed work of drawing oil sample of power system transformer filling type sleeve pipe can be widely used in.
