Description

A voltage transformer with protection structure

Technical Field

The utility model relates to the technical field of voltage transformers, in particular to a voltage transformer with a protection structure.

Background Art

Voltage transformers are similar to transformers and are instruments used to transform voltage. However, the purpose of transformers to transform voltage is to facilitate the transmission of electrical energy, so the capacity is very large, and is generally calculated in kilovolt-amperes or megavolt-amperes; while the purpose of voltage transformers to transform voltage is mainly to power measuring instruments and relay protection devices, to measure the voltage, power and electrical energy of the line, or to protect valuable equipment, motors and transformers in the line when a line fault occurs.

After searching, the authorization announcement number CN220456204U is a voltage transformer with a protective structure, and its structure includes a voltage transformer body, a protective box, a front cover, a latch and a hinge. The protective box is provided with a protective mechanism inside, and the protective mechanism includes sealing plates fixedly mounted on the inner walls of the left and right sides and the inner wall of the bottom of the protective box. In a voltage transformer with a protective structure, since heat is transferred from bottom to top, the heat conducting plate will quickly absorb the heat generated by the voltage transformer body, and the absorbed heat will be discharged through the exhaust barrel through the action of the heat exhaust fan, reducing the heat accumulated inside the protective box, preventing the voltage transformer body from being damaged due to overheating, and the sealing strip is connected to the inside through the action of the sealing plate and the heat conducting plate, so as to seal the voltage transformer body, prevent the voltage transformer body from being oxidized by rain and air, and improve the service life of the voltage transformer body.

However, when the voltage transformer with the protective structure is in use, since the top of the exhaust barrel lacks a protective structure for intercepting impurities, some impurities (such as fallen leaves, dust, etc.) are easily allowed to enter the protective box. The impurities that enter will fall on the surface of the heat conducting plate, which is easy to affect the heat dissipation effect of the voltage transformer. In addition, the internal heat exhaust fan is difficult to disassemble and is inconvenient to replace after damage.

Therefore, it is necessary to provide a voltage transformer with a protection structure to solve the above technical problems.

It is worth noting that the circuits, electronic components and modules involved in the present utility model are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present utility model does not involve improvements to software and methods.

The working principle of the voltage transformer with protection structure provided by the utility model is as follows:

The voltage transformer body including the protection box 1 belongs to the prior art. When it is used, the voltage transformer body will generate more heat after working. At this time, the heat conduction plate collects the heat through the effect of temperature conduction. At this time, the heat exhaust fan 3 will gradually discharge the heat collected by the heat conduction plate through the exhaust barrel 5, so that the temperature inside the protection box 1 cannot affect the voltage transformer body. At the same time, through the action of the sealing strip, the sealing plate, the heat conduction plate and the sealing ring, it is difficult for external air to enter the interior of the protection box, thereby achieving a good sealing effect.

After the voltage transformer body is improved by the present solution, the wire mesh 6 can effectively intercept impurities such as fallen leaves and dust, thereby preventing impurities from entering the protective box 1 from the exhaust barrel 5, and also preventing oversized objects from entering, so that a large amount of impurities can be prevented from falling on the surface of the heat conducting plate, which is beneficial to improving the heat dissipation effect. When it is necessary to clean the impurities on the wire mesh 6, the servo motor 14 is started, and the servo motor 14 drives the reciprocating screw 15 to rotate, and the reciprocating screw 15 drives the connecting block 16 to slide on the sliding groove, and the connecting block 16 drives the horizontal plate 17 to move horizontally, and the horizontal plate 17 drives the brush 18 to move horizontally, so that the bristles on the brush 18 clean the wire mesh 6, and clean up the impurities attached to the wire mesh 6, which is more convenient to clean.

When the heat exhaust fan 3 is damaged and needs to be replaced, the two pull rods 2 are pulled, and the two pull rods 2 will drive the two sliders 11 to squeeze the two springs 10. In the process of squeezing the two springs 10, the two sliders 11 will also drive the two support rods 12 away from each other, and the two support rods 12 will drive the two mounting sleeves 13 away from each other, so that the two mounting sleeves 13 can be separated from the two mounting blocks 4. After separation, the disassembly of the heat exhaust fan 3 is completed, and then the new heat exhaust fan 3 is placed in the appropriate position. The new heat exhaust fan 3 must also be installed with mounting blocks 4 on both sides, and then the two pull rods 2 are released. After loosening, the two springs 10 will automatically push the two sliders 11 to move, and the two sliders 11 will drive the two support rods 12 close to each other, and the two support rods 12 will drive the two mounting sleeves 13 close to each other, so that the two mounting sleeves 13 can be buckled with the two mounting blocks 4. In this way, the installation of the new heat exhaust fan 3 is completed, and the replacement is convenient and labor-saving, and the use effect is better.
