When the data deviation is too large, a remote alarm will be issued to realize remote monitoring and intelligent management.

[0012] 3.

DETAILED DESCRIPTION
[0021] The present invention is further described below in conjunction with the accompanying drawings: Example
[0022] As attached Figure 1 To Attachment Figure 5 As shown: The present invention discloses an intelligent box-type power transformer, which comprises a base 1, a voltage box 2, a cabinet door 3, and a metal cover 4.

The processor 23 has the effect of detecting the circuit. The metal cover 4 is tilted left and right, which has the effect of guiding the liquid to flow, and can be remotely intelligently monitored, so that the base 1 is placed in an exposed environment outside, and the inside of the voltage box 2 is opened for inspection through the cabinet door 3. The metal cover 4 guides the rainwater above to prevent the rainwater from staying on the surface of the metal cover 4, and then the current is output after changing the voltage from the transformer 22. The voltage is detected by the processor 23, and the distribution mechanism 24 is remotely controlled to generate wind blowing upward, so that the wind flows from the top to the surrounding outer shell plate 21, thereby isolating the outer shell plate 21 and the top of the distribution mechanism 24 from the outside temperature, preventing the temperature of the outer shell plate 21 from being transmitted to the inside after being exposed to the outside.
[0023] The outer shell plate 21 is provided with a sealing plate w1, a current limiting block w2, a heat conducting plate w3, an isolating plate w4, a blocking block w5, an arc plate w6, and a metal plate w7. The metal plate w7 is parallel to the heat conducting plate w3. The lower ends of the metal plate w7 and the heat conducting plate w3 are embedded in the upper end of the interior of the isolating plate w4. The current limiting block w2 is installed in the metal plate w7. The blocking block w5 is embedded in the interior of the heat conducting plate w3. The arc plate w6 is installed on the inner side of the sealing plate w1. The isolating plate w4 is installed on the outer side of the sealing plate w1. The sealing plate w1 and the heat conducting plate w3 are parallel to each other. The lower end of the isolating plate w4 is embedded in the surface of the plastic plate 25. The dispersing mechanism 24 is embedded in the sealing plate w1 and On the side of the heat conducting plate w3, the blocking block w5 and the current limiting block w2 are staggered, and the insulating plate w4 is made of wood and has a poor thermal conductivity. Therefore, the heat emitted by the wind adsorption transformer 22 of the dissipation mechanism 24 is guided to the inside of the sealing plate w1, and flows outward from the blocking block w5 on the heat conducting plate w3 under the guidance of the arc plate w6, and then the heat flows between the heat conducting plate w3 and the metal plate w7 to the position of the current limiting block w2. At the same time, the heat generated by the metal plate w7 being exposed to the outside is driven by the wind to flow outward in the gap between the heat conducting plate w3 and the metal plate w7, thereby dissipating the internal heat while ensuring that the external heat will not be transmitted to the inside, thereby preventing the internal heat from rising due to exposure to the sun.
[0024] Among them, the current limiting block w2 is provided with an opening plate w21, a plastic rod w22, and an annular groove w23. The opening plate w21 is attached to the outside of the plastic rod w22, and the annular groove w23 is embedded in the opening plate w21. The opening plate w21 is embedded in the metal plate w7. The opening plate w21 is made of rubber material, has the characteristic of easy deformation and movement, and is in a conical state and inclined at 60 degrees. There are two annular grooves w23, which are distributed in an annular manner inside the opening plate w21, and sponge material is provided between the annular grooves w23 for connection, which has the effect of making the opening plate w21 telescopic and movable, so that the wind blows toward the inside of the opening plate w21, and the wind drives the plastic rod w22 to be unbalanced and move outward, so that the opening plate w21 is deformed and expanded outward, and then the annular groove w23 is exposed under the deformation of the opening plate w21, and a larger gap is generated by the expansion and contraction of the sponge material, so that the wind drives the heat to flow evenly outward from the position of the annular groove w23.
[0025] Among them, the blocking block w5 is provided with a gap plate w51, a plane plate w52, and a flow hole w53. The flow hole w53 is located inside the plane plate w52, and the gap plate w51 is attached to the side of the plane plate w52. The gap plate w51 is made of sponge material, has a large gap, and is easy to absorb dust. A circular hole is provided inside the gap plate w51, and the hole is located on the side of the flow hole w53. Then, the wind flows through the gap between the metal plate w7 and the heat conducting plate w3 to the flow hole w53 on the plane plate w52, and then drives the heat to be dissipated from the holes of the gap plate w51 to the outside, and the external dust is absorbed when entering from the gap plate w51, blocking most of the dust from entering. At the same time, the dust stays between the metal plate w7 and the heat conducting plate w3, and is blocked by the unidirectional flow limiting block w2, thereby preventing the entry of external dust. The specific usage and function of this embodiment are as follows: In the present invention, the base 1 is placed in an exposed environment, the interior of the voltage box 2 is opened for inspection through the cabinet door 3, the metal cover 4 guides rainwater from above to prevent rainwater from staying on the surface of the metal cover 4, and then the current is output after the voltage is changed from the transformer 22, the voltage is detected by the processor 23, and the distribution mechanism 24 is remotely controlled to generate wind blowing upward, so that the wind flows from the top to the surrounding outer shell plate 21, thereby isolating the outer shell plate 21 and the top of the distribution mechanism 24 from the external temperature, preventing the temperature of the outer shell plate 21 from being transmitted to the inside after being exposed to the outside sun.
[0026] In the present invention, the heat emitted by the wind-absorption transformer 22 of the dissipation mechanism 24 is guided to the inside of the sealing plate w1, and the wind is guided by the arc plate w6 to flow outward from the blocking block w5 on the heat-conducting plate w3, and then the heat flows between the heat-conducting plate w3 and the metal plate w7 to the position of the current-limiting block w2, and the wind causes the opening plate w21 to expand and contract outward, and then the annular groove w23 is exposed under the deformation of the opening plate w21, and a larger gap is generated by the expansion and contraction of the sponge material, so that the wind drives the heat to flow evenly outward from the position of the annular groove w23, and at the same time the metal plate w7 is exposed to the outside. The generated heat is driven by the wind to flow outward in the gap between the heat conducting plate w3 and the metal plate w7, so that the wind flows into the flow hole w53 on the flat plate w52, and then drives the heat to be dissipated from the holes of the gap plate w51 to the outside, and the external dust is adsorbed when entering from the gap plate w51, blocking most of the dust from entering. At the same time, the dust stays between the metal plate w7 and the heat conducting plate w3, and is blocked by the unidirectional flow limiting block w2, thereby preventing the entry of external dust, thereby dissipating the internal heat while ensuring that the external heat will not be transmitted to the inside, preventing the internal heat from rising due to exposure to the sun.
