When the air intake assembly 3 works, the air suction fan 303 can pump outside air into the air guide pipe 304, the air in the air guide pipe 304 can be conveyed into the fixed cover 201, the air can enter the fixed box 101 through the through groove 203 after passing through the air guide groove 208, in the process, the air passes through the plurality of partition plates 306, water vapor in the air can flow along the surface of the partition plates 306 due to the fact that the cross section of the partition plates 306 is in a "<" structure, in the process of flowing along the surface of the partition plates 306, the air is condensed into water drops, and the water drops can slide downwards along the surface of the partition plates 306 due to the fact that the side face of the partition plates 306 is in a J-shaped structure, so that the water drops can be prevented from entering the inside of the device.
When the outside rains, the rainwater falls on the surface of the guide plate 103 and flows to the upper part of the sieve plate 403, and the rainwater can enter the water storage tank 401 after being filtered by the sieve plate 403, so that the automatic replenishment of the rainwater is realized.
In the transformer substation use, the heat conduction medium in the heat conduction pipe 204 is in the even flow process all the time, simultaneously the heat conduction pipe 204 is contradicted with the fixed cover 201 all the time, thereby the heat conducted on the fixed cover 201 can directly contact the heat conduction pipe 204, be convenient for slow down the temperature rising efficiency of power transformation equipment, simultaneously when there is the rainwater to exist in the water storage tank 401, there is partial contact between the wall body of the water storage tank 401 and the fixed cover 201, thereby the position heat conduction rate that makes the fixed cover 201 and the water storage tank 401 contact is accelerated, the thermal expansion efficiency of the fixed cover 201 slows down, namely when there is water in the water storage tank 401, when the temperature in the fixed box 101 is the same, the temperature of the fixed cover 201 body is lower at this moment, the expansion volume of the fixed cover 201 is smaller, and the compression amount to the heat conduction pipe 204 is smaller.
When rainwater is stored in the water storage tank 401, and the depth of the rainwater can be in contact with the heat dissipation pipe 206, at this time, the inside of the fixed cover 201 is heated and expanded along with the temperature increase of the power transformation equipment, and the fixed cover 201 is heated and expanded along with the temperature increase of the power transformation equipment, so that the pressure of the fixed cover 201 on the heat conduction pipe 204 is increased, and the pipe wall of the heat conduction pipe 204 is made of elastic materials, so that the expansion of the fixed cover 201 limits the pipe diameter of the heat conduction pipe 204, so that the flow velocity of heat conduction medium in the heat conduction pipe 204 is increased, the bonding area between the fixed cover 201 and the heat conduction pipe 204 is increased, so that the heat conduction rate is increased, and when the heat conduction medium in the heat conduction pipe 204 flows to the position of the heat dissipation pipe 206, because the heat dissipation pipe 206 is in contact with the rainwater in the water storage tank 401 at this time, the heat emitted by the radiating pipe 206 can be absorbed by rainwater, the heat conducting medium is always at a lower temperature, the heat generated by the power transformation equipment is absorbed by the heat conducting pipe 204, the temperature on the fixed cover 201 is reduced when the heat conducting rate of the heat conducting pipe 204 is higher than the heat generating rate of the power transformation equipment, the volume of the fixed cover 201 is reduced, the heat conducting pipe 204 is not extruded, the temperature rising rate of the fixed cover 201 is reduced when the heat conducting rate of the heat conducting pipe 204 is lower than the heat generating rate of the power transformation equipment, the heat conducting pipe 204 is still in a continuously expanded state, the heat conducting pipe 204 is continuously extruded, the contact area between the fixed cover 201 and the heat conducting pipe 204 is increased, the flow rate of the heat conducting medium in the heat conducting pipe 204 is increased, and after the heat of the power transformation equipment reaches a certain value, at this time, the flow rate of the gas in the fixed box 101 is increased outwards, the gas can be identified by a wind direction sensor on the exhaust fan 303, the operation of the exhaust fan 303 is controlled, the temperature in the fixed box 101 is neutralized by using the external temperature, and the temperature inside the transformer substation is stabilized by using the mutual coordination between the exhaust fan 303 and the heat conducting tube 204.
When there is no rainwater in the water storage tank 401, the heat dissipation tube 206 is exposed in the water storage tank 401, the water storage tank 401 and the fixing cover 201 are in heat conduction process, the water storage tank 401 cannot perform water cooling on heat generated by the fixing cover 201, the temperature in the fixing cover 201 is enabled to be almost the same as the temperature in the fixing cover 101, and the cooling control process of the air draft fan 303 and the heat conduction tube 204 when no water exists in the water storage tank 401 is the same, and redundant description is omitted.
When the fixed box 101 is always in an extreme condition, for example, is at a high temperature for a long time or when flame occurs in the fixed box 101 to cause abnormal temperature rise, the fixed cover 201 is in an expanded state continuously, the outer wall of the heat conducting pipe 204 is extruded, and the pipe body of part of the heat conducting pipe 204 can be broken along with the continuous expansion of the fixed cover 201, so that the heat conducting medium in the heat conducting pipe 204 overflows to cool the fixed box 101 or inhibit the flame from being spread, and the safety of the power transformation equipment in the use process is improved to a certain extent.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present utility model, and although the present utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present utility model.
