3, this instrument is easy to assembling, convenient improvement.Corresponding adjustment can be made according to the special purpose device that to be drawn oil sample to this by the concrete condition of getting oilhole of getting oily transformer, get oilhole with what adapt to different size.
Accompanying drawing explanation
Fig. 1 is the structural representation of oil-filled transformer oil sampling tool of the present utility model.
Main element label declaration:
The utility model:
1: get oilhole 2: get oil pipe line 3: flow valve
4: oil-collecting pipeline 5: filter screen 6: gathering-device
Embodiment
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and embodiment of the present utility model is described.
Refer to Fig. 1, as shown in the figure, the preferred embodiment of a kind of oil-filled transformer oil sampling tool of the present utility model, it comprises gets oil pipe line 2, flow valve 3, filter screen 5 and gathering-device; Described one end of getting oil pipe line 2 be with oil-filled transformer get the interface that oilhole 1 matches, its other end is connected with the inlet end of described flow valve 3, the endpiece of described flow valve 3 connects an oil-collecting pipeline 4, described oil-collecting pipeline 4 end is provided with filter screen 5, and described oil-collecting pipeline 4 leads to described gathering-device 6.By with oil-filled transformer get that oilhole 1 matches get oil pipe line 2, can make to get to be formed between oilhole 1 and this instrument and be tightly connected.Whereby, oil flows through to be got oilhole 1 and flows to and get oil pipe line 2, then flow to oil-collecting pipeline 4 via the flow valve 3 opened, oil stream flows directly into gathering-device 6 after oil-collecting pipeline 4 end filters via filter screen 5.Whole process is hedged off from the outer world sealing, ensure that the oil in transformer is not contaminated, and can not be fuel-displaced uncontrolled and excessively discharge oil because getting oilhole 1; The setting of flow valve 3, can control the oily flow flowed in accurate quantitative analysis ground, prevent excessive oil extraction, affect the normal operation of transformer; By the setting of filter screen 5, make the solid impurity in the oil sample removal oil circuit collected.
Further, in its preferred embodiment, the oil pipe line 2 of getting of described oil-filled transformer oil sampling tool is connected cooperation place is provided with packing washer with described oilhole 1 of getting, and further enhances and gets being tightly connected of oilhole and oil-filled transformer oil sampling tool of the present utility model.
Oil-filled transformer oil sampling tool of the present utility model, in one specific embodiment, described in get oilhole 1 and be provided with external thread, described in get oil pipe line 2 and be provided with the internal thread got oilhole 1 external thread with this and match; By the mode of threaded engagement, reach and get oil pipe line 2 and get being sealed and matched of oilhole 1 and be connected.But this connected mode just wherein one preferably embodiment, gets oil pipe line 2 and gets one end that oilhole 1 is connected and also can connect by other modes such as clips.
