The utility model relates to an automatic transformer charging device, which comprises transformer inside and a compressed air cylinder. The compressed air cylinder is connected to an air inlet hole of a two-position three-way valve through an air cylinder relief valve and a first air pipe, an air outlet hole of the two-position three-way valve is connected to a first end of a three-way valve communicated with the transformer inside through a second air pipe, a second end of the three-way valve is connected to a pressure gauge through a third air pipe, a third end of the three-way valve is connected to a pressure feedback port of the two-position three-way valve through a fourth air pipe, and an exhaust hole of the two-position three-way valve is connected to the outside. The automatic transformer charging device has the advantages that the device automatically charges a transformer at any time under unattended conditions, ensures internal insulation of the transformer without being affected by moisture during storage or transport, greatly saves cost and also guarantees product quality.
Description
Technical field
The utility model relates to a kind of inflator, relates in particular to a kind of inflator of transformer.
Background technique
Large oil immersed formula transformer is in transportation process, for reducing hauled weight, transformer inside is oil-filled and only charge into dry air or high pure nitrogen, the gas that charges into must be moisture free, and for making extraneous gas can not enter transformer inside, its internal gas has malleation (0.025MPa), thereby avoid the moisture in the atmosphere to enter transformer inside, pollute TRANSFORMER INSULATING MATERIAL, insulating part is made moist, and then reduce or lose the performance of insulating material.The inner a spot of moisture contamination of transformer is fatal for transformer.
May there be leak source in the transformer fuel tank weld seam or the sealing surface of transformer in transit, causes gas leakage, and pressure is descended; Gas also can make the transformer internal pressure produce conversion with the variation of ambient temperature in addition, when pressure is increased to 0.10MPa when above, may make oil tank of transformer produce distortion, thereby cause weld cracking, and gas leaks fully, and insulation is made moist.
At present, the transformer transportation process takes the variation of carving monitoring transformer internal gas pressure, a lot of transformer production producers can send the special messenger to escort transformer, escort personnel will repeatedly be checked gas pressure every day, when transformer pressure goes beyond the scope, escort personnel can the manual unlocking valve be inflated transformer or is exitted.The high-power transformer hundreds of ton that generally weighs, haulage time is longer, and particularly when sea-freight and railway transport, condition is very arduous, so transformer inflation transportation is a headachy problem that perplexs the industry always.
Summary of the invention
The utility model technical issues that need to address have provided a kind of transformer self-filler, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: transformer inside; Also comprise a compressed air bottle; Described compressed air bottle is connected to the inlet hole of two-position three-way valve by the gas cylinder reduction valve and first tracheae; The air outlet hole of two-position three-way valve is connected to first end of the three-way valve that communicates with transformer inside by second tracheae; Second end of three-way valve is connected to pressure gauge by the 3rd tracheae; The 3rd end of three-way valve is connected to the air pressure feedback port of two-position three-way valve by the 4th tracheae; The exhaust port of two-position three-way valve be connected outward.
Compared with prior art, the beneficial effects of the utility model are: can be under unattended situation, and be the transformer inflation automatically at any time, guarantee the storage of transformer built-in electrical insulation or do not make moist in transit, save cost greatly, also guarantee quality of product simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged view of two-position three-way valve among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
By Fig. 1, Fig. 2 as seen: the utility model comprises: transformer inside 1; Also comprise a compressed air bottle 2; Described compressed air bottle 2 is connected to the inlet hole 51 of two-position three-way valve 5 by the gas cylinder reduction valve 3 and first tracheae 4; The air outlet hole 52 of two-position three-way valve 5 is connected to first end of the three-way valve 7 that communicates with transformer inside 1 by second tracheae 6; Second end of three-way valve 7 is connected to pressure gauge 9 by the 3rd tracheae 8; The 3rd end of three-way valve 7 is connected to the air pressure feedback port 53 of two-position three-way valve 5 by the 4th tracheae 10; The exhaust port 54 of two-position three-way valve 5 be connected outward.
The utility model is combined into three-way valve compressed air bottle, gas cylinder reduction valve, two-position three-way valve, pressure gauge is in the same place by tracheae, forms a kind of gas pressure and can be to its device of inflation automatically can judged in the transformer.
The two-position three-way valve that adopts in the utility model is the product of prior art.
This two-position three-way valve working principle: utilize gas pressure to make main valve plug motion and gas and changing is flowed to, added control signal pressure rises gradually during pressurized control. and when air pressure was increased to the operating pressure of spool, main valve just commutated; Added gas control signal pressure reduces when unloading pressure-controlled, when being reduced to a certain force value, and the main valve commutation.
On gas circuit, the two-bit triplet solenoid valve has an inlet hole " 3 " (connecing gas cylinder), an air outlet hole " 2 " (connecing the transformer body), an exhaust port " 1 ".
During inflation: the dry gas in the gas cylinder arrives " 3 " port of two-position three-way valve by reduction valve and tracheae, be the long state of opening at this moment between " 3-2 ", so gas is inflated in transformer by port " 2 ", in the time of inflation, feed back to reaction force of main valve plug of two-position three-way valve by the three-way valve on the transformer, when pressure is increased to certain value (0.025MPa), the main valve plug action, " 3-2 " is separated, stops to the transformer air feed; When the transformer internal pressure is reduced to certain value (0.015), " 3-2 " reopens, when transformer is increased to certain value owing to the gas pressure that expands with heat and contract with cold (0.05MPa), and the outside exhaust of " 1 " port (to 0.025MPa).
