By the aid of the onsite vacuum oil-changing system, functions such as vacuum pumping and vacuum holding of the transformer and emptying and filling of oil are achieved, and onsite oil-changing operation of the transformer is convenient.
Description
Technical field
The vacuum that the utility model the relates to a kind of transformer working site system of changing oil.
Background technology
Generally speaking; Transformer with welded closure need not be changed insulating oil in the product life cycle, but under the special climate environmental condition or when special requirement is arranged, then must carry out oil plant by customer requirement and change operation; And generally; Must carry out in the vacuum equipment in special use to oiling transformer, must transport this transformer back factory like this, can have a strong impact on normal power supply.
In order to improve the after-sale service quality, shorten oil changing interval, reduce maintenance cost, under the constant situation of this body structure of transformer, how to dispose a suitable system can accomplish the work of changing oil of whole vacuum at the scene, be insider's problem demanding prompt solution.
The utility model content
The purpose of the utility model is to provide the on-the-spot vacuum of a kind of transformer system of changing oil, so that can carry out the operating system that the insulating oil vacuum is changed for transformer at client's distribution scene.
The technical scheme that realizes above-mentioned purpose is: the on-the-spot vacuum of a kind of transformer system of changing oil; Be used for the transformer that to change oil; This transformer comprises repairing hole and fuel outlet; It is characterized in that the said vacuum system of changing oil comprises a sliding vane rotary vacuum pump, a vacuum meter, a table oil pump, a socket device, an oil discharging valve and first connecting line and second connecting line, the repairing hole of said transformer is connected with vacuum meter through said interface arrangement on the one hand; Connect first connecting line through said interface arrangement on the other hand, and connect said sliding vane rotary vacuum pump by this first connecting line; The fuel outlet of said transformer connects said oil pump through said oil discharging valve by said second connecting line.
In the on-the-spot vacuum of above-mentioned transformer was changed oil system, said interface arrangement was the reducing tee device.
In the on-the-spot vacuum of above-mentioned transformer was changed oil system, the reducing tee of said interface arrangement was connected with transformer, sliding vane rotary vacuum pump and vacuum meter with gas thread, straight tube, plug mode respectively.
Owing to adopted above-mentioned technical scheme, the transformer that need are changed oil couples together, at the scene by technological requirement accomplish the old oil of putting of transformer, vacuumize, fidelity is empty, irritate the complete operation procedure of changing oil of new wet goods.The on-the-spot vacuum of the utility model transformer system of changing oil can be on-the-spot for transformer vacuumizes the operation of changing insulating oil at client's distribution, and be easy to carry, and can reach technological requirement, shortens whole oil changing interval, reduces the cost of changing oil.
Description of drawings
Fig. 1 is the vacuum of the utility model transformer working site system configuration sketch map of changing oil.
Embodiment
In order to understand the technical scheme of the utility model better, below through embodiment particularly and combine accompanying drawing at length to explain.
See also Fig. 1; The utility model, the on-the-spot vacuum of promptly a kind of transformer system of changing oil is used for the transformer 6 that need change oil; This transformer comprises repairing hole 3 and fuel outlet 4; Be characterized in that the vacuum system of changing oil comprises a sliding vane rotary vacuum pump 7, a vacuum meter 1, a table oil pump 8, a socket device 2, an oil discharging valve 5 and the first connecting line L1 and the first connecting line L2
The repairing hole 3 of transformer is connected with vacuum meter 1 through said interface arrangement 2 on the one hand, connects the first connecting line L1 through said interface arrangement 2 on the other hand, and connects said sliding vane rotary vacuum pump 7 by this first connecting line L1; The fuel outlet 4 of transformer connects said oil pump 8 through oil discharging valve 5 by the second connecting line L2.
The transformer that need are changed oil by the above-mentioned vacuum system of changing oil couples together, at the scene by technological requirement accomplish the old oil of putting of transformer, vacuumize, fidelity is empty, irritate the complete operation procedure of changing oil of new wet goods.Utilize the repairing hole of transformer to carry out vacuumizing through interface arrangement; Utilize the fuel outlet of transformer to put old oil, irritate the fresh oil operation through valve.
Said interface arrangement utilizes the reducing tee device that a vacuum pump, a vacuum meter, a transformer are connected together.The reducing tee of interface arrangement is connected with transformer, vacuum pump, vacuum meter with gas thread, straight tube, plug mode respectively.
The process of changing oil according to vacuum:
1, vacuum pump and vacuum meter are tightly connected through interface arrangement and repairing mouth; Oil pump is tightly connected through second tube connector (flange connections) and oil discharging valve.
2, at first by oil pump through drain oil and oil discharging valve with old oily emptying, close fuel outlet valve after the affirmation.
3, start vacuum pump then, through being connected in the interface arrangement on the transformer repairing hole, the transformer of old oil emptying is vacuumized; During whole vacuumizing; Should keep watch on the indicating value that is connected the vacuum meter on the interface arrangement, when indicating value reaches process stipulation, promptly close vacuum pump.
4, this moment, transformer should be in the vacuum hold mode; The indicating value of vacuum meter must be kept watch on during this time, when indicating value surpasses process stipulation, vacuum pump be in time opened and closed; Transformer is under the suitable vacuum state all the time, until the vacuum retention time of having passed through process stipulation.
5, having passed through the vacuum maintenance after date that requires, through drain oil and oil discharging valve fresh oil is sucked transformer again, continue to open and close vacuum pump simultaneously, after pasta arrives the design code position, close fuel outlet valve to keep transformer under the specified vacuum degree.
That 6, removes oil pump and oil discharging valve is connected recovery oil discharging valve normal condition; Remove interface arrangement from the repairing hole at the fidelity of regulation after the empty time, recover repairing hole normal condition.
The utility model has been realized emptying, the can function of the vacuumizing of transformer, fidelity sky and oil plant, is convenient to on-the-spot to the transformer operation of changing oil.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
