The use of the moisture-adsorption device for transformer and the course of work are as follows：The first stopple 14 is opened, from drier entrance
Granular drier 9 is filled into the inside of cylinder 1, as shown in Fig. 2, again by the first stopple 14 after drier 9 loads
Fill in drier import.The grain size of the drier 9 is more than the aperture of first through hole 31, and the grain size of the drier 9 is more than gear
The internal diameter of pipe 5, the grain size of the drier 9 are more than the aperture of the second through-hole 61；This makes drier 9 be located at the top of Taper Pipe 6
And drier 9 is located between the lateral wall and the madial wall of cylinder 1 of vertical tube 3.The lower end of connecting tube 13 and oil tank of transformer are connected
Logical, the lower end of bundle of capillary tubes at this time 7 puts in oil tank of transformer and is contacted with transformer oil, since the bundle of capillary tubes 7 is by more
71 boundling of capillary forms, as shown in Figure 3；Due to the presence of capillary 71, under capillary action, the transformation in capillary 71
Device oil level can be higher than the transformer oil liquid level in connecting tube 13, inside transformer oil and the moisture-adsorption device for transformer
Contact area between air, the moisture contributed in transformer oil are distributed to the inside of cylinder 1, to help to improve moisture absorption
Efficiency.Motor 2 can drive shaft 21 to rotate, and shaft 21 can drive vertical tube 3 to rotate, and the vertical tube 3 of rotation is constituted with gear pipe 5 to be stirred
Paddle is to be stirred the drier 9 inside cylinder 1 so that drier 9 can fully absorb the moisture inside cylinder 1, together
When can also allow the drier 9 far from vertical tube 3 that can fully be utilized so that absorb more abundant；Meanwhile the presence of vertical tube 3,
So that the contact area between the moisture inside cylinder 1 and drier 9 further increases, moisture absorption efficiency is helped to improve.
When needing replacing drier 9, the second stopple 15 is opened, starts motor 2, the drier 9 inside cylinder 1 is from drying
Agent exit is discharged, and the drier outlet can be arranged multiple；Presence and drier outlet setting due to Taper Pipe 6 exist
The top of 6 lower end of Taper Pipe and the junction of 1 inner wall of cylinder, this enables the 6 remaining drier 9 in top of Taper Pipe in the work of gravity
With it is lower so that drier 9 flow out it is more convenient, thorough.Relative to tablet, Taper Pipe 6 is so that in the drier 9 and cylinder 1 of bottom
Contact area bigger between the moisture in portion, moisture sorption effect higher.Meanwhile the presence of Taper Pipe 6, also so that transformer oil and drying
Agent 9 completely cuts off.
Further, thermal insulation layer 16 is installed on the outside of 1 lower semisection of the cylinder, the outside of 1 upper semisection of the cylinder is solid
Equipped with multiple radiating fins 17.Since transformer can continue to generate heat in the process of running, the temperature of transformer oil is higher；By
It is connected to oil tank of transformer in the lower end of connecting tube 13, along with the presence of thermal insulation layer 16 makes 1 lower semisection of cylinder not easy heat radiation,
So that the internal temperature of 1 lower semisection of cylinder is higher；Radiating fin 17 can speed up heat dissipation, this makes the inside of 1 upper semisection of cylinder
Temperature is relatively low, and under the action of the temperature difference, thermal convection current easily occurs for the inside of cylinder 1；Since 1 lower semisection of cylinder is close to transformer oil,
So that the humidity content at this is larger；The generation of thermal convection current can speed up the gaseous fluid inside cylinder 1, help to improve suction
Wet efficiency.
Due under the double action of bundle of capillary tubes 7 and thermal convection current, having been able to significantly improve moisture absorption efficiency；For section
The about energy, the motor 2 can periodic running, if motor 2 daily rotatable 10 minutes, remaining time does not rotate.
Further, the side wall of the gear pipe 5 is provided with multiple fourth holes 51, the side wall of the vertical tube 3 be provided with
The fifth hole 32 that the inner cavity of gear pipe 5 is connected.The presence of fourth hole 51 and fifth hole 32 so that the tide inside cylinder 1
Gas contacts more abundant with drier 9, helps to improve moisture absorption efficiency.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
