Abstract
The utility model provides an oil extraction device for a transformer. The oil extraction device comprises an oil extraction pipe, wherein a quick coupling is arranged at an inlet of the oil extraction pipe, an oil extractor is connected at an outlet of the oil extraction pipe, and a three-way change valve is arranged on the oil extraction pipe. The oil extraction device has the advantages of being simple in structure and convenient to use, the whole sampling process is carried out in a full-sealing manner, the phenomena that gas chromatography detection analysis results are influenced as moist gas in air enters an oil sample or gas in the oil sample escapes is avoided, detection errors caused by sampling are avoided, and whether the transformer goes wrong can be truly reflected, so that the transformer is timely maintained.
Description
Technical field
The utility model relates to a kind of transformer and gets oily device.
Background technology
In the Repair of Transformer process, utilize gas chromatograph the gas of insulating oil oil sample in transformer and content analysis out, judging whereby the inner incipient fault character of transformer and the order of severity, is the most effectual way whether check transformer equipment inside exists the latency fault.
At present, when dissolving in the oil sampling, generally use the 500ml ground glass stoppered bottle, first clean oil discharging valve with clean cotton gauze, open throttle with spanner, bleed off " dead band oil ", then use apparatus body oil flushing 500 mL ground glass stoppered bottles, then drain the oil and get completely, cover at last bottle stopper.This complex operation, it is large that sampling method is got oil mass, because oil sample is exposed in air for a long time, cause that in air, wet gas is easy to immerse in sample, and the characteristic gas that dissolves in oil (particularly hydrogen) loss rate is higher, make errors of analytical results larger, easily cause erroneous judgement disconnected, affect equipment safety operation.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of easy to use, salable transformer of getting oil and gets oily device, uses this device to draw oil sample, can avoid due to draw oil sample to be exposed to and cause test figure inaccurate in air.
Technical solution of the present utility model is:
A kind of transformer is got oily device, and its special character is: have one to get oil pipe, described import of getting oil pipe is provided with rapid-acting coupling, is connected with oil drawer in described outlet of getting oil pipe, described getting, three-way diverter valve is housed on oil pipe.
Described oil drawer has a pump barrel and inserts the interior piston of pump barrel, and described pump barrel front end is provided with oil-in.
The beneficial effects of the utility model:
Simple in structure, easy to use, the hermetically sealed operation of whole sampling process, can in oil sample or oil sample, the gas loss affect the gas chromatographic detection analysis result because airborne wet gas enters, the detection error of having avoided sampling to cause, can react really transformer inside and whether have fault, in order in time keep in repair.
Description of drawings
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 rinses the schematic diagram of connecting line when being the utility model sampling;
The schematic diagram of emptying oil drawer when Fig. 3 is the utility model sampling;
Fig. 4 is the schematic diagram of the utility model sampling.
In figure: 1-rapid-acting coupling, 2-gets oil pipe, 3-three-way diverter valve, 4-oil drawer, 401-oil-in, 402-pump barrel, 403-piston.
Embodiment
As shown in Figure 1, this transformer is got oily device, there is one to get oil pipe 2, described import of getting oil pipe 2 is connected with rapid-acting coupling 1, described outlet of getting oil pipe 2 is connected with oil drawer 4, described oil drawer 4 has a pump barrel 402 and inserts the interior piston 403 of pump barrel 402, and described pump barrel 402 front ends are provided with oil-in 401; Described getting, three-way diverter valve 3 is housed on oil pipe 2.
during sampling, rapid-acting coupling 1 is connected with oil pumping valve for transformer, open oil pumping valve for transformer, as shown in Figure 2, first three-way diverter valve 3 is placed in flushing connecting line position, with " dead oil " in transformer through three-way diverter valve 3 emptyings, then, rotate three-way diverter valve 3, as shown in Figure 3, emptying oil drawer position when three-way diverter valve 3 is placed in sampling, promote the piston 403 of oil drawer 4, empty G﹠O in oil drawer 4 is got rid of, be rotated further three-way diverter valve 3, as shown in Figure 4, three-way diverter valve 3 is placed in the sample position, oil sample injects oil drawer 4 automatically under the static pressure effect, when getting enough oil samples, close three-way diverter valve 3 and oil pumping valve for transformer, sampling finishes.
Claims (2)
