Abstract
The utility model discloses an automatic sampling device of transformer oil appearance, including sample connection and introduction port, first pipeline, exhaust bag and second pipeline have been set gradually between sample connection and the introduction port, be provided with the valve on the first pipeline. The utility model discloses when the operation, oily appearance is kept apart with human, has avoided the oily kind of injury to skin, improves staff's operating condition, has avoided oily appearance to take place to leak, leads to the filth on ground, traditional sampling device can not carry out the drawback that oil appearance was taked under having solved special weather reason, effectively improve work efficiency, will become the one man operation by original three people operation.
Description
[technical field]
The utility model belongs to oil sample sampling field, relates to a kind of transformer oil sample automatic sampling device.
[background technology]
Oil chromatogram analysis analyzes present stage to judge that power transformer interior fault is the sensitiveest, effective means, but at oil analysis, the situation of test figure inconsequent is often there is in analysis, whether inside transformer exists abnormal conditions to need repeatedly sample analysis to determine, this is mainly due in oil chromatogram analysis, caused by the error of measurement data, the reason of error is caused to be mainly because operated by personnel is improper on the one hand, gas is demarcated exists error, because in sampling process, oil sample enters air on the other hand, moisture or the ingress of air time is longer etc. that situation causes test figure abnormal.
The oil sample collecting device of transmission is all adopt needle tubing directly to contact with transformer sample tap, in operation, often can there is oily leakage situation, transformer oil can cause ground to be heavily polluted after leaking, and contaminated ground one is to being eliminated in two years, particularly at rainy weather, outside humidity reaches more than 90%, traditional oil sample collecting device does not possess sampling condition, the error that the oil sample taked like this is measured is larger, particularly winter, northern area temperature is low especially, traditional sampling method, sampling vessel often can be caused to damage, serious meeting injures sampling people and goes smoothly, and damage transformer sample valve, cause the infringement of equipment, establish to equipment and leave potential safety hazard, cause transformer oil impregnate.
In this external traditional sampling, general needs three people co-operating just can complete, one people's sampling, one people controls fuel tap, people's monitoring, just have a large amount of oil stream splashes during misoperation out, if the splash to skin of oil stream can not be removed in time, can skin be corroded, damage is caused to skin, causes inefficiency.
[utility model content]
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, a kind of transformer oil sample automatic sampling device is provided, this device has redesigned new fluid circuit and material, flow control valve has been installed, control flow at any time according to the size of flow to sample, achieve isolated outside air function, avoid oil sample ingress of air and moisture, improve the accuracy of oil analysis.
For achieving the above object, the utility model is achieved by the following technical solutions:
A kind of transformer oil sample automatic sampling device, comprises sample tap and injection port, is disposed with the first pipeline, Exhaust airbag and the second pipeline between sample tap and injection port; First pipeline is provided with valve.
The utility model further improves and is:
Described injection port is provided with the oversheath for sealing.
Described first pipeline and the second pipeline adopt transparent pipeline.
Described first pipeline and the second pipeline adopt corrosion-resistant pipeline.
Described first pipeline and the second pipeline adopt polyfluortetraethylene pipe or fluorine rubber-pipe.
Described first pipeline and the second pipeline diameter are 4mm.
Described first pipeline is connected by quick plug with valve and sample tap.
Compared with prior art, the utility model has following beneficial effect:
The utility model is when operating, and oil sample and human body are isolated, and avoid the injury of oil sample to skin, improve the condition of work of staff, avoid oil sample and leak, cause the filth on ground; Under solving special weather reason, traditional sampler can not carry out the drawback that oil sample is taked; Effectively improve work efficiency, operate by three original people, become one man operation.
[accompanying drawing explanation]
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Wherein: 1 is sample tap; 2 is pipeline one; 3 is injection port; 4 is valve; 5 Exhaust airbags; 6 is pipeline two; 7 is oversheath.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further detail:
See Fig. 1, the utility model comprises sample tap 1 and injection port 3, is disposed with the first pipeline 2, Exhaust airbag 5 and the second pipeline 6 between sample tap 1 and injection port 3; First pipeline 2 is provided with valve 4.Injection port 3 is provided with the oversheath 7 for sealing.First pipeline 2 and the second pipeline 6 adopt diameter to be that the teflon of 4mm or fluororubber obtain and corrosion-resistant transparent pipeline.First pipeline 2 is connected by quick plug with valve 4 and sample tap 1.
The utility model is mainly divided into two parts, and a part is the connection of this device pipeline all parts; Another part is operating process in sampling process.The utility model sample tap is connected with valve by the first pipeline 2, and the first pipeline 2 is connected with the second pipeline 6 by Exhaust airbag, and the second pipeline 6 is connected with injection port 3, and for preventing injection port 3 from leakage of oil occurring, injection port 3 installs oversheath 7 additional and seals.
Sampling operation flow process of the present utility model:
Injection port 3 is connected with oil-filled kind equipment sample valve, open oil-filled kind equipment valve, under the pressure itself of oil, oil stream flows to the second pipeline 6, pipeline oil sample is first by Exhaust airbag 5, by the air scavenge in pipeline, oil sample enters valve 4, open the oily stream of valve 4 to enter into pipe and get outlet 1, thief hatch with adopt vessel and be connected, under the self gravitation effect of oil, oil sample enters into sampling vessel automatically, after the numerical value of sampling close to regulation, now need slowly closing valve 4, oil stream slowly stops flowing into sampling vessel, close the valve of the oily equipment of sampling, open valve 4, utilize sampling vessel to be all pumped in sampling vessel by the oil in pipeline to go, after the oil in pipeline all enters sampling vessel, pull up plug-in sample tap, all complete sampling.
Sampler in the utility model needs fully to rinse pipeline before every sub-sampling, generally needs, to flushing of pipeline 10 seconds, to prevent the impact of oil sample on this sub-sampling of remnants last time.Pipeline in the utility model adopts the transparent pipeline of polyethylene conduit of 4mm, both effectively can prevent the corrosion to pipeline, also effectively can find whether there is exception in sampling.Transformer oil has corrosive attack, so will consider this some during design, proves to adopt the metastable polyfluortetraethylene pipe of chemical property and fluorine rubber-pipe as working line through test of many times according to this characteristic.In order to increase work efficiency, make work more convenient, when selecting pipeline and equipment connection, select quick plug, as long as such operating personnel pipeline is docked with valve and sample tap gently, just can work.
Above content is only and technological thought of the present utility model is described; protection domain of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, within the protection domain all falling into the utility model claims.
