Abstract

The utility model discloses a closed sampler comprising a needle tube, wherein the needle tube is connected with a hose; the hose is connected with one port of a T-tube; another port of the T-tube is connected with a sampling valve of a transformer; and the third port of the T-tube is connected with a waste oil recovery device. In the utility model, oil output from the transformer directly flows into the needle tube after passing through the T-tube and is directly placed on an inspection table of a chromatograph through the needle tube, without being in contact with air during the intermediate process; and fault gas in the oil can not be volatilized, so that test is more accurate. Besides, both the T-tube and the needle tube are fixed on a bracket, and an operator can operate the needle tube and a valve with two free hands when using the closed sampler, so that the sampler is used more conveniently.

Description

Airtight sampler
Technical field
The utility model belongs to field of power transmission, is specifically related to a kind of device that extracts oil sample from transformer.
Background technology
Transformer is transformer station's usual means, and transformer various problems may occur after operation a period of time.When detecting, be the oil that takes out in the transformer, by the various compositions of chromatograph analyzing and testing oil.Prior art is directly the oil droplet in the transformer to be gone in the test tube, then invisible spectro oil is put into chromatogram and detects.The shortcoming of this means is: oil flows into test tube, transfers to the chromatographic process from test tube from transformer, and oil contacts with outside air, and at this moment the failure gas in the oil will evaporate in the air, causes follow-up chromatogram test to produce measuring error.
The utility model content
The technical problems to be solved in the utility model is that the oil that comes out in the transformer causes test to be forbidden because of contact with the external world in testing process, and a kind of can be in the transformer airtight oily airtight sampler of getting is provided.
The technical solution of the utility model realizes in the following manner:
A kind of airtight sampler comprises needle tubing, and needle tubing links to each other with flexible pipe, and flexible pipe links to each other with a mouth of threeway, and another of threeway mouthful links to each other with the sample valve of transformer, and the 3rd mouth of threeway links to each other with drain oil recovery equipment.
Described needle tubing is arranged on support one end, and threeway is arranged on the support other end.
Above-mentioned needle tubing one end is provided with positioning baffle in the preferred version.
In the utility model, the oil that comes out from transformer flows directly into after threeway the needle tubing, by needle tubing oil is directly put on the chromatographic check-out console, does not contact with air in the pilot process, and the failure gas in the oil can not volatilize, and it is more accurate to test.In addition, threeway and needle tubing all are fixed on the support, and operating personnel can vacate two manual manipulation needle tubings and valve in use, use more convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises needle tubing 4, and needle tubing 4 links to each other with flexible pipe 3, and flexible pipe 3 links to each other with a mouth of threeway 2, and another mouthful of threeway 2 links to each other with the sample valve of transformer 1, and the 3rd mouth of threeway 2 links to each other with drain oil recovery equipment 6.
Described needle tubing 4 is arranged on support 5 one ends, and threeway 2 is arranged on support 5 other ends.
The utility model use is as follows: threeway 2 one ends are linked to each other with the sample valve of transformer 1, and second port of threeway 2 links to each other with flexible pipe 3, and the 3rd port of threeway 2 links to each other with drain oil recovery equipment 6.Before the sampling, at first open the valve 2-2 of the threeway that links to each other with drain oil recovery equipment 6, the part waste oil that accumulates in the transformer 1 is flowed out, valve-off 2-2 afterwards, open the valve 2-1 of the threeway 2 that links to each other with flexible pipe 3, under the pressure of transformer 1, the oil in the transformer 1 flows in the needle tubing 4 automatically.After the oil in the needle tubing 4 reaches the quantity of test request, needle tubing 4 is taken off from flexible pipe 3, adding in the chromatogram tester oil directly, test gets final product.Oil is contactless with air in the whole process, can not influence the validity of detection.
In addition, the utility model can also be provided with positioning baffle 7 at needle tubing 4 one ends.Because it is certain that chromatogram detects the amount of needed sample, adds after the positioning baffle 7, can guarantee that the amount of each needle tubing 4 interior oil of being got just in time is that the chromatogram detector is used.
