Description
Technical Field
The utility model belongs to the technical field of the transformer, in particular to device is alleviated to inside and outside atmospheric pressure of transformer ripple oil tank.
Background
At present, the conventional transformer transportation adopts closed transportation, particularly a 10KV small-capacity fully-sealed transformer, the internal expansion and contraction force is mainly counteracted by the elastic deformation of a corrugated wall, the deformation resistance is weak, the conventional technological measures are not thorough in drying, the gas alarm possibility in the operation process is increased, and the operation of the transformer is influenced. The mode is convenient and time-saving, but when the mode is applied to a high-altitude transformer, the great air pressure difference from the plain to the plateau can cause the deformation of the oil tank in different degrees. The strength of the oil tank is enhanced, the oil tank is effective, but the investment is high, the effect is low, the verification time is long, the transportation is only one stage of the life cycle of the transformer in the long run, and a simpler mode is adopted for treatment.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a remedy prior art not enough, provide a device is alleviated to inside and outside atmospheric pressure of transformer ripple oil tank convenient to transportation, operation safety, simple structure.
The utility model discloses a realize through following technical scheme:
the utility model provides a device is alleviated to inside and outside atmospheric pressure of transformer ripple oil tank, includes transformer body and oil conservator, characterized by: the oil conservator is connected with a capsule air outlet pipe, and the capsule air outlet pipe is connected with the breathing moisture absorber through a metal hose.
The breathing moisture absorber is connected with an inflation valve through a reducer pipe joint, and a pressure gauge is arranged on the inflation valve.
The breathing moisture absorber is arranged on the transformer body.
The utility model has the advantages that: the problem of inside and outside air pressure difference in the process of transporting the transformer in a fully-sealed mode is solved, air pressure balance to the transformer body in the transporting process can be achieved after the oil conservator is detached, and the transformer transporting device is suitable for transporting the whole transformer and the separated transformer.
Drawings
The present invention will be further described with reference to the accompanying drawings.
FIG. 1 is a schematic structural view of the whole transportation of the transformer of the present invention;
FIG. 2 is a schematic structural view of the split transportation of the transformer of the present invention;
in the figure, 1 transformer body, 2 oil conservator, 3 capsule outlet pipe, 4 metal hose, 5 breathing moisture absorber, 6 reducer union, 7 charging valve, 8 manometer.
Detailed Description
The attached drawing is a concrete embodiment of the utility model. This embodiment includes transformer body 1 and oil conservator 2, and oil conservator 2 connects capsule outlet duct 3, and capsule outlet duct 3 passes through metal collapsible tube 4 and is connected with breathing desiccator 5. The breathing moisture absorber 5 is connected with an inflation valve 7 through a reducer pipe joint 6, and a pressure gauge 8 is arranged on the inflation valve 7. The breathing moisture absorber 5 is installed on the transformer body 1.
Adopt the utility model discloses a device is alleviated to inside and outside atmospheric pressure of transformer ripple oil tank, to the high altitude product of the little volume of small capacity, increase the capsule and store up oil tank, the breathing desiccator 5 of storing up oil tank 2 is fixed in and protects fixed measure on transformer body 1 during the transportation, breathes desiccator 5 and stores up the capsule outlet duct 3 of oil tank 2 and is connected with metal collapsible tube 4. In the transportation process, the external gas can enter the capsule air outlet pipe 3 through the breathing moisture absorber 5 and the metal hose 4, and the capsule air outlet pipe 3 can realize the isolation of the external gas and the internal transformer oil and can completely release the air pressure (no matter positive pressure or negative pressure) inside the transformer; in addition, the mode can be directly installed on the ground on site, and operations such as site installation, oil injection and the like are reduced.
For large-volume high-altitude products, the oil conservator 2 needs to be detached due to the large volume of the products, and a ventilation device, namely an inflation valve 7 can be added on the main conduit, so that the interior of the transformer is communicated with the atmosphere, the difference between the internal pressure and the external pressure is eliminated, and the principle is the same as that of small-volume products. The structure can be popularized to the problem of overlarge pressure difference between the inside and the outside of the transformer in the transportation process caused by seasonal factors and latitude regional factors. By adopting the kerosene gas coherent drying method, the drying is more thorough, the moisture in the body is less, and the possibility of ionizing hydrocarbon gas under the running condition of the transformer is lower.
