[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] An environmentally friendly dry-type transformer includes a main enclosure 1 and a dry-type transformer body 2 disposed inside the main enclosure 1. The bottom of the main enclosure 1 adopts an open design. A dustproof interception net 3 is fixedly installed inside the main enclosure 1 and below the dry-type transformer body 2. U-shaped ventilation slots 4 are opened on both sides of the main enclosure 1 and below the dustproof interception net 3.

[0028] A protective top cover 5 is fixedly connected to the top of the main housing 1. A cooling fan 6 is installed on the top of the main housing 1 and inside the protective top cover 5. The bottom of the cooling fan 6 is connected to the inside of the main housing 1. Air intake nets 7 are fixedly connected to both sides of the protective top cover 5. The air intake nets 7 are inclined. A partition plate 8 is fixedly connected inside the main housing 1 and above the dry-type transformer body 2. Multiple ventilation holes 10 are evenly opened on the partition plate 8.

[0029] like Figure 1The cooling fan 6 is an existing technology that can be detected by an external temperature sensor and automatically start when the temperature is high, achieving energy saving and environmental protection. The dry-type transformer body 2 has heat sinks on the outside, which can improve the heat dissipation effect of the dry-type transformer body 2. The outer side of the main tank 1 has a door that can be opened and closed. Through the partition plate 8 with ventilation holes 10 set below the cooling fan 6, the airflow blown into the main tank 1 by the cooling fan 6 can be divided by the ventilation holes 10 and evenly blown into the interior of the main tank 1, so as to achieve uniform heat dissipation of the dry-type transformer body 2.

[0030] A bent flow guide sleeve 11 is fixedly connected to the top of the main housing 1 and inside the protective top cover 5. One end of the bent flow guide sleeve 11 passes through one side of the main housing 1 and extends to the outside of the main housing 1.

[0031] like Figure 1 and Figure 7 The guide sleeve 11 has a cavity with a filter screen (not shown in the figure). Even if some rain enters the protective top cover 5, it can flow out through the cavity of the guide sleeve 11 and out the other end of the guide sleeve 11, thus enhancing the waterproof capability.

[0032] A heat insulation plate 12 is fixedly connected to the top of the protective top cover 5, and inclined guide plates 13 are fixedly connected to both sides of the protective top cover 5 and above the air intake net 7.

[0033] like Figure 1 and Figure 7 The heat insulation plate 12 prevents direct sunlight from causing a rapid increase in the internal temperature of the protective top cover 5, and the inclined guide plate 13 can guide rainwater to prevent rainwater from flowing back from the top of the protective top cover 5 to the air intake net 7.

[0034] A linear array of support rods 14 are fixedly connected between the two sides of the inner wall of the main housing 1 and below the dry-type transformer body 2. Multiple circular holes 15 are evenly opened on the support rods 14.

[0035] like Figure 1 , Figure 5 and Figure 6 The circular hole 15 on the supporting rod 14 can enhance the ventilation capacity of the dry-type transformer body 2.

[0036] A fixing pipe 16 is fixedly connected to the supporting round rod 14. A horizontal support plate 17 is fixedly connected to the top of the fixing pipe 16. An installation block 18 is fixedly connected to the top of the horizontal support plate 17. A fixing bolt 19 is provided on the installation block 18.

[0037] like Figure 1 , Figure 5 and Figure 6The horizontal support plate 17 provides support for the dry-type transformer body 2. The dry-type transformer body 2 has screw holes, so that the fixing bolts 19 can pass through the mounting block 18 and the dry-type transformer body 2 for threaded connection, and install and fix the dry-type transformer body 2.

[0038] Guide sleeves 20 are fixedly connected to both sides of the main housing 1. The end of the guide sleeve 20 located outside the main housing 1 is bent downward. A wire hole 21 is provided on the guide sleeve 20. A sealing plug 22 is provided at the end of the guide sleeve 20 located outside the main housing 1. Protective sleeves 23 are fixedly connected to both sides of the main housing 1. The protective sleeves 23 are fitted onto the outer surface of the guide sleeves 20.

[0039] like Figure 1 The lines connecting the dry-type transformer body 2 and external equipment can pass through the wire hole 21. The protective sleeve 23 provides rain protection from the outside. The sealing plug 22 is inserted into one end of the wire hole 21 and can be manually removed.

[0040] The working principle of the environmentally friendly dry-type transformer provided by this utility model is as follows:

[0041] When the cooling fan 6 is activated to dissipate heat inside the main housing 1, the cooling fan 6 draws external airflow into the protective top cover 5 through the air intake baffle 7, and then blows it into the interior of the main housing 1 to dissipate heat from the dry-type transformer body 2. Finally, the hot airflow can be blown out to the outside of the main housing 1 through the bottom of the main housing 1 or the U-shaped ventilation slot 4.

[0042] Compared with related technologies, the environmentally friendly dry-type transformer provided by this utility model has the following beneficial effects:

[0043] This invention uses U-shaped ventilation slots 4 on both sides of the main housing 1 and below the dustproof mesh 3 as air outlets to prevent rainwater from entering the main housing 1. It also uses the air inlet mesh 7 as an air inlet and the inclined guide plate 13 to prevent rainwater from entering the main housing 1 through the air inlet, thus providing moisture-proof protection for the dry-type transformer body 2 inside the main housing 1. At the same time, the inclined setting of the air inlet mesh 7 can prevent dust or debris from adhering to the surface of the air inlet mesh 7 and affecting the airflow capacity when the cooling fan 6 is cooling the dry-type transformer body 2.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
