Embodiment

The structural representation for the power transformer enclosure aerating device that Fig. 1 provides for the utility model embodiment.Such as Fig. 1 institutes Show, the utility model provides a kind of power transformer enclosure aerating device, including rise seat 1 and gas supply assembly 3, rise seat 1 has Sealed hollow cavity, transformer 2 is arranged in hollow cavity.

Gas supply assembly 3 is connected with hollow cavity, for continuing to supply into hollow cavity, so as to be full of inside hollow cavity Dry gas.

It should be noted that the power transformer enclosure aerating device, dry to filling inside rise seat 1 by gas supply assembly 3 Pathogenic dryness body, prevents the rise inside transformer 2 of seat 1 from being made moist in transportation.Replace traditional oil-filled using inflation, oil body is compared with gas Body weight, inflation traffic department reduces transport load-carrying.Meanwhile, oil body is discharged waste after shipping, generally, add product into This.

It is preferred that, gas supply assembly 3 includes source of the gas 31 and connecting pipe 32, and the first end and source of the gas 31 of connecting pipe 32 connect Logical, the second end of connecting pipe 32 is connected with hollow cavity.

It is preferred that, the pressure gauge 4 of the hollow cavity internal pressure for detecting rise seat 1 is installed on rise seat 1.

It should be noted that being provided with pressure gauge 4 on rise seat 1, its internal pressure is detected, the flow of inflation is adjusted. Internal pressure is monitored at any time in transportation, to ensure internally dry environment.

It is preferred that, it is additionally provided with check valve 5 between connecting pipe 32 and rise seat 1.

It should be noted that setting check valve 5 between connecting pipe 32 and rise seat 1, the non-return using check valve 5 is made Seat 1 is raised with make it that gas can only be flowed to by source of the gas 31.Check valve 5 can select straight check valve or angle check valve.

It is preferred that, check valve 5 is fixed on rise seat 1 by flange 6.

It should be noted that check valve 5 is fixed on rise seat 1 by flange 6, is connected by flange 6 and not only meet removable The annexation of formula is unloaded, and the pressure-bearing property of flange 6 is preferably, can meet the circulation of gases at high pressure.

It is preferred that, source of the gas 31 is compressed gas cylinder.

It should be noted that rise seat 1 is in transit, inevitably occurs gas leakage, to keep the rise inside gas of seat 1 Body is sufficient and dry environment, and the compressed gas cylinder is carried simultaneously in transportation, when air pressure reduce, by gas cylinder to raising seat Inflated in 1.

It is preferred that, the gas in gas cylinder is anhydrous air or anhydrous inert gas.

It should be noted that gas can select anhydrous air in the gas cylinder, dry environment is kept.It also can select anhydrous inert Gas, prevents the part minimum gas infringement transformer 2 in air.Such as from helium, neon or argon gas.

It is preferred that, inside hollow cavity when full of dry gas, the air pressure in rise seat 1 is equal to 0.025MPa.

It should be noted that when raising in seat 1 full of dry gas, it is ensured that gas pressure is equal to 0.025MPa, meets Dry environment.Pressure crosses conference and damages the rise outer wall of seat 1, is also not easy to raise the transport of seat 1.

The power transformer enclosure aerating device that the utility model is provided, traditional oil-filled transport is replaced using inflation transport, It ensure that the transformer 2 inside power transformer enclosure 1 prevents from making moist in transportation, and avoid traditional oil-filled transporter Oil body is wasted in method, reduces product cost.
