Description
Technical field
The one kind that the utility model is related to draws oil sample contact switching device, and particularly a kind of oil-filled main transformer of power plant draws oil sample
Contact switching device.
Background technology
The oil-filled main transformer of power plant need to periodically draw oil sample progress high-quality chemical examination, the 220kV transformer cycles be three months once,
Former sampling method is that a probe tube is set in main transformer bottom, and Valve controlling is socketed in sampling with being about 30cm emulsion tubes during sampling
Guan Shang, opens sample cock, and oil product outflow accesses oil sample with sampling bottle, oil sample closes valve after the completion of accessing, removes latex
Pipe.Therefore, existing sampling method has that oil product easily pollutes, oil product wastes the serious and sampling work time.
Utility model content
The purpose of this utility model is to draw oil sample contact switching device there is provided a kind of oil-filled main transformer of power plant.It has
Fast sampling can be carried out, reduce oil product waste and prevent the contaminated feature of oil product by having.
The technical solution of the utility model：The oil-filled main transformer of power plant draws oil sample contact switching device, including is screwed in change
Second component on depressor probe tube, second component bottom is provided with first component；The second component includes the treasured of hollow structure
Tower head, pagoda head upper end is provided with the screwed hole corresponding with transformer probe tube, and pagoda head lower end is provided with the outer spiral shell of hollow structure
Line pipe；The first component includes being connected with male-pipe and is the internal thread tube piece of hollow structure, and internal thread tube piece lower end is set
Have to be provided with needle tubing thief hole, needle tubing thief hole in the probe tube of cylindrical structure, probe tube and be filled with silicagel pad.
The oil-filled main transformer of foregoing power plant draws oil sample in contact switching device, and the outer section of the internal thread tube piece is six
Side shape structure.
The oil-filled main transformer of foregoing power plant draws oil sample in contact switching device, and the needle tubing thief hole includes and internal thread
The oil sample storage holes that pipe fitting hollow space is connected, silicagel pad is located in oil sample storage holes；The oil sample storage holes lower end is provided with
Needle tubing import, and diameter of the diameter less than oil sample storage holes of needle tubing import.
Compared with prior art, the utility model is by the way that second component is screwed on probe tube, by second component with
The close connection of first component and use needle tubing extract oil product and are sampled, and can be rapidly performed by installing, to greatest extent
The efficiency that improves oil sampling, the waste for not resulting in oil product and effectively oil sample can be prevented to be contaminated；Second component
Closely it is connected by screwed hole with transformer probe tube, is easy to smoothly draw the oil product in transformer, and oil sample is second
Components interior circulates, and effectively can prevent oil sample from being polluted by environment；It is closely coupled with second component by first component,
Needle tubing thief hole is set in first component, and isolated oil product and air by silicagel pad, passes through needle pierces mistake
Silicagel pad extracts oil sample, both ensure that the sampling quality and speed of oil product, additionally it is possible to prevent oil product outflow from causing to waste.To sum up institute
State, the utility model, which has, which can carry out fast sampling, reduce oil product wastes and prevent the contaminated feature of oil product.
