Abstract
The utility model relates to insulating oil sampling of power operation equipment and in particular relates to a fully sealed insulating oil sampler. The fully sealed insulating oil sampler comprises a sampling injector, wherein a front-end through hole (1) of the sampling injector is connected with a connecting hole A of a three-way valve (2) in a sealed mode; a connecting hole B of the three-way valve (2) is connected with a hose in a sealed mode; and the three-way valve (2) is provided with a rotary handle (3) which drives a valve element to rotate. The fully sealed insulating oil sampler also comprises a waste oil collection box, wherein a cutting sleeve is arranged outside a box body of the waste oil collection box; and a cylinder of the sampling injector is positioned in the cutting sleeve, and the front end of the sampling injector is arranged above the waste oil collection box. The fully sealed insulating oil sampler is reasonable in design and simple in structure, and the problem that distortion of dissolved gas in oil is caused so as to generate an experimental error due to contact loss between insulating oil and atmosphere in the sampling process is solved.
Description
Technical field
The utility model relates to the insulating oil sampling of operation power equipment, is specially the hermetically sealed sampling thief of a kind of insulating oil.
Background technology
Chromatography test, as the conventional belt electro-detection project of operation power equipment, can be found the latency fault of an oil-filled equipment such as main transformer, CT delicately.But, because chromatography test link is more, there is certain cumulative errors, fault correct judgment is brought to impact.In all too many levels, sampling error is to cause the principal element of test error.In sampling process, because oil sample contacts the walk-off-loss causing with air.
Therefore, lack at present a kind of hermetically sealed sampling thief that is exclusively used in insulating oil sampling.
Summary of the invention
The utility model, in order to solve in sampling process due to formation testing and atmosphere contact loss, causes oil dissolved gas distortion, causes the problem of test error, provides a kind of insulating oil hermetically sealed sampling thief.
The utility model is to adopt following technical scheme to realize:
The hermetically sealed sampling thief of a kind of insulating oil, comprises sampling syringe, and the front end through hole of described sampling syringe and the connector A of T-valve are tightly connected, and connector B and the flexible pipe of described T-valve are tightly connected; Described T-valve is provided with the rotary handle that drives valve core rotation.
When use, first pull down the outer cover at equipment sample valve place, clean sample valve, on sample valve connecting hose to the connector B of T-valve, the connector A of sampling syringe connecting tee valve.When sampling, open equipment fuel outlet valve.Rotate rotary handle, connector B, the C of T-valve are connected, connector A seals, and drains the dead oil at fuel outlet valve place.Rotate rotary handle, connector A, the B of T-valve are connected, connector C sealing, pulls the piston core bar (syringe is made up of with the cylindrical shell of through hole and the piston core bar that matches front end) of syringe, and oil sample enters employing syringe.Again rotate rotary handle, connector A, the C of T-valve are connected, connector B sealing, the piston core bar of pushing syringe drains oil and the air in syringe, be rotated further rotary handle, connector A, the B of T-valve are connected, connector C sealing, the piston core bar of pushing syringe enters in syringe the insulating oil in equipment under static pressure, get after requirement wait the oil sample that insulate, sample valve on closing device, takes off sampling syringe, the openings of obturaging sampling syringe front end with Capsule rapidly, labelled, put into oil sample box.Finally, clean the oil stain of equipment sampling place, keep T-valve and flexible pipe well, cover sample valve outer cover.
In order to collect the waste oil in employing process; protection of the environment; in this sampling thief, also comprise waste oil collecting box, the box body of described waste oil collecting box is provided with cutting ferrule outward, and the front end that the cylindrical shell of described sampling syringe is positioned at cutting ferrule and sampling syringe is placed in waste oil collecting box top.When use, sampling syringe is snapped in the cutting ferrule of waste oil collecting device, and the connector C of T-valve is aimed to waste oil collecting box, by the waste oil collecting in sampling process in waste oil collecting box.
The utility model is reasonable in design, simple in structure, has solved in sampling process due to insulating oil and atmosphere contact loss, causes oil dissolved gas distortion, causes test error.
Brief description of the drawings
Fig. 1 is part-structure schematic diagram of the present utility model.
In figure, 1-front end through hole, 2-T-valve, 3-rotary handle.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
The hermetically sealed sampling thief of a kind of insulating oil, comprises sampling syringe, and the front end through hole 1 of described sampling syringe is tightly connected with the connector A of T-valve 2, and connector B and the flexible pipe of described T-valve 2 are tightly connected; Described T-valve 2 is provided with the rotary handle 3 that drives valve core rotation; As shown in Figure 1.
Also comprise waste oil collecting box, the box body of described waste oil collecting box is provided with cutting ferrule outward, the front end that the cylindrical shell of described sampling syringe is positioned at cutting ferrule and sampling syringe is placed in waste oil collecting box top, and the connector C of T-valve is placed in waste oil collecting box top, and waste oil collecting is arrived in waste oil collecting box.
The hermetically sealed sampling thief of above-mentioned insulating oil has function simple in structure, applicable.
