[0002] The box-type transformer concentrates the traditional transformer in a box-type housing. It has the characteristics of small size, light weight, low noise, low loss and high reliability. With the rapid development of cities, the number of community substations has increased year by year, and the corresponding installation and disassembly of transformers is also very frequent. When installing community substations, cranes and forklifts cannot enter due to terrain restrictions, so mobile box-type transformers appeared.

[0003] However, the existing box-type transformer has a publication number of CN206460901U on the patent website, which only plays a role of better operational linkage. The heat dissipation performance of the box-type transformer is relatively low, which will affect the service life of the internal components of the box. In addition, the convenience of maintenance work of the box-type transformer is relatively low, and it is not convenient to quickly repair the internal components of the transformer box. Summary of the invention

[0009] Furthermore, the surface of the solar cell panel is arc-shaped, the solar cell panel is located on the inner side of the guide plate, and the solar cell panel is embedded in the top plate.

[0010] Furthermore, two guide plates are provided, and the two guide plates are symmetrically arranged on the front and back sides of the top plate, the two guide plates are arranged to be inclined downward, and the guide plates are welded to the top plate.

[0011] Furthermore, the position of the mortise groove corresponds to the position of the tenon, the inner diameter of the mortise groove is equal to the outer diameter of the tenon, and the mortise groove is embedded in the box body.

[0012] Furthermore, four rollers are provided, and the four rollers are respectively located at four corners of the bottom of the box body, and the rollers are fixedly connected to the box body by threads.

[0013] Furthermore, two fans are provided, and the two fans are respectively located opposite to the heat dissipation holes, and the fans are embedded in the box.

[0014] (III) Beneficial effects

[0015] The present invention provides a box-type transformer that is easy to maintain and has the following beneficial effects:

[0016] (1) This box-type transformer that is easy to maintain is improved and enhanced on the original basis. It is equipped with a fan, a solar panel, a battery and a heat dissipation hole. When sunlight shines on the solar panel, the solar panel will convert the heat energy in the sunlight into electrical energy and store it in the battery. When the transformer is running, a large amount of heat will be generated. At this time, the battery will provide electrical energy for the fan. At this time, the fan will start to run, causing the internal fan blades to rotate rapidly, thereby promoting the flow rate of air inside the box. The heat dissipation hole runs through the box door, which can connect the internal and external environments of the box, thereby facilitating the heat generated by the transformer to be discharged to the outside of the box. Since the fan is located directly opposite the heat dissipation hole, the heat generated by the transformer can be quickly discharged to the outside of the box, which is beneficial to accelerate the heat dissipation rate of the device.

[0017] (2) This type of box-type transformer that is easy to maintain is improved and enhanced on the original basis. It is equipped with a box door, an inspection panel and rollers. When the internal components of the box are to be inspected, the box is first pushed to an open area. Since the bottom of the box is equipped with rollers, the rollers can reduce the friction resistance of the box during the movement of the box, which is conducive to improving the maneuverability and flexibility of the device. Then, hold the handrail with your hand and pull the box door outward, so that the front of the transformer is exposed, which is convenient for the inspection of the front of the transformer. Then hold the back of the box with your hand. Open the knob valve and turn it counterclockwise to shrink the tenon into the inside of the inspection plate. The tenon will then come out of the tenon groove, thus completing the separation between the inspection plate and the box body. Finally, hold the knob valve to fold the inspection plate upward to expose the back of the transformer, facilitating the normal maintenance work. Open the inspection plates on both sides of the box body in turn in the same way to expose both sides of the transformer inside the box, thereby completely exposing all sides of the transformer body to the maintenance personnel, which is conducive to improving the convenience of maintenance work.

[0018] (3) This box-type transformer that is easy to maintain is improved and enhanced on the original basis. It is equipped with a top plate, a guide plate and a dustproof net. When the device is operating normally, the transformer will quickly conduct hot air out of the box through the heat dissipation holes. A dustproof net is arranged on the inner side of the heat dissipation holes. It can prevent external dust and debris from entering the box through the heat dissipation holes through fine meshes, which is beneficial to reducing the impact of external dust on the transformer. The dustproof net is a multi-layer stacking design, which is beneficial to improving the dustproof effect of the dustproof net. When it rains, rainwater will drip on the top plate. Since the top plate surface is curved, it is not conducive to water accumulation, thereby accelerating the rate at which rainwater flows on the surface of the top plate. At this time, the rainwater will flow along the curved top plate to the position of the top plate. The guide plate is arranged to be tilted downward, so that the rainwater on the top plate can quickly flow back to the box shell. The width of the top plate is greater than the width of the box, thereby effectively preventing rainwater from entering the box from the heat dissipation holes, which is beneficial to improving the protection of the transformer inside the box.
