[0045] During the heat dissipation process, in order to prevent rainwater from entering the interior of the transformer equipment cabinet, a rain shield is often provided at the heat dissipation opening. However, due to the influence of the wind, a small amount of rainwater will still enter the interior of the transformer equipment cabinet, which is likely to damage the circuit inside the transformer equipment cabinet and pose a safety hazard. Therefore, in this embodiment, a transformer equipment cabinet is proposed to collect the rainwater entering the interior of the transformer equipment cabinet and discharge the collected rainwater from the transformer equipment cabinet, so as to improve the waterproof performance of the transformer equipment cabinet and thus enhance the safety performance of the transformer.

[0046] Specifically, please refer to Figure 1, the transformer equipment cabinet includes a cabinet body frame 1, a heat dissipation plate 2, a top plate 3, a bottom plate 4 and a water storage plate 5. The top plate 3 is hermetically arranged on the top of the cabinet body frame 1, the bottom plate 4 is hermetically arranged on the bottom of the cabinet body frame 1, the heat dissipation plate 2 is hermetically arranged on the side of the cabinet body frame 1, and heat dissipation holes 21 are evenly distributed on the heat dissipation plate 2. Each heat dissipation hole 21 communicates with the inside of the transformer equipment cabinet; the water storage plate 5 is arranged on the heat dissipation plate 2 and is inside the transformer equipment cabinet. The water storage plate 5 can be combined with the heat dissipation plate 2 to form a water storage tank, and the bottom of the water storage tank is not higher than the lowermost heat dissipation hole 21.

[0047] It can be understood that the heat dissipation plate 2, the top plate 3 and the bottom plate 4 are hermetically arranged on the cabinet body frame 1, which can prevent rainwater from entering the inside of the transformer equipment cabinet, and can ensure the internal heat dissipation of the transformer equipment cabinet under the action of the heat dissipation holes 21. When a small amount of rainwater enters the inside of the transformer equipment cabinet through the heat dissipation holes 21, it will be collected in the water storage tank and then flow out of the transformer equipment cabinet through the heat dissipation holes 21 to increase the waterproof performance of the transformer equipment cabinet, thereby improving the safety performance of the transformer.

[0048] In addition, the cabinet body frame 1 is formed by splicing profiles. In this embodiment, the cabinet body frame 1 is a cuboid with six faces. Among them, the top plate 3 and the bottom plate 4 are respectively located at the top and bottom of the cuboid, and four heat dissipation plates 2 are provided and are respectively arranged on the other four faces of the cuboid.

[0049] Particularly, the area where all the heat dissipation holes 21 are located is in the upper middle part of the entire heat dissipation plate 2, and all the heat dissipation holes 21 occupy one-third to one-half of the entire area of the heat dissipation plate 2. Such a setting can further improve the heat dissipation performance of the cabinet body frame 1.

[0050] Please refer to Figure 2 and Figure 3 for reference. The water storage plate 5 includes a first plate 51, a second plate 52, a third plate 53 and two fourth plates 54 that are vertically arranged in sequence. The first plate 51 is arranged on the heat dissipation plate 2, the third plate 53 faces the heat dissipation plate 2, and the top of the third plate 53 is above the lowermost heat dissipation hole 21; the two fourth plates 54 are respectively arranged at both ends of the second plate 52, and the two fourth plates 54 are between the third plate 53 and the heat dissipation plate 2. It can be understood that the first plate 51 is connected to the heat dissipation plate 2 by bolts, and the first plate 51 can be attached to the heat dissipation plate 2 to increase the connection strength between the water storage plate 5 and the heat dissipation plate 2. Under the action of the second plate 52, a gap can be generated between the third plate 53 and the heat dissipation plate 2, and the two fourth plates 54 provided can block both ends of the gap to form a water storage tank.

[0051] Furthermore, the second plate 52 is tilted in the height direction, and the heat dissipation hole 21 is at the lowest point of the second plate 52. It can be understood that when a small amount of rainwater enters the water storage tank through the heat dissipation hole 21, since the second plate 52 is tilted, the rainwater can flow along the second plate 52 to the heat dissipation hole 21, so that the rainwater can be discharged in time, so as to further increase the waterproof performance of the transformer equipment cabinet, thereby improving the safety performance of the transformer.

[0052] In this embodiment, the transformer equipment cabinet further includes a rain shield 6, which is arranged on the side of the heat dissipation plate 2 away from the water storage plate 5, and is arranged on the heat dissipation hole 21. The bottom of the rain shield 6 is provided with an opening 61, and the opening 61 is connected to the heat dissipation hole 21. It can be understood that the rain shield 6 is preferably arc-shaped, so that the periphery of the heat dissipation hole 21 can be blocked. Compared with a flat rain shield, the rain shield 6 can block rainwater from all directions, so as to further improve the waterproof performance of the transformer equipment cabinet. In addition, during the heat dissipation process, the heat inside the transformer equipment cabinet can be removed from the opening 61, and the rainwater discharged from the heat dissipation hole 21 is also discharged from the opening 61.

[0053] In order to facilitate the maintenance and repair of the electrical components of the transformer equipment cabinet, in this embodiment, the heat sink 2 is rotatably arranged on the cabinet frame 1; the transformer equipment cabinet also includes a locking structure 7, which is used to lock the heat sink 2 to the cabinet frame 1. The locking structure 7 is arranged inside the transformer equipment cabinet and has a locked state and an unlocked state. In daily work, the locking structure 7 is in the locked state to ensure the sealing between the heat sink 2 and the cabinet frame 1. When the electrical components of the transformer equipment cabinet need to be maintained and repaired, the locking structure 7 is switched from the locked state to the unlocked state.

[0054] Specifically, the locking structure 7 includes a first gear 71, a fixed block 72, a slider 73, a second gear and a rotating member 74. The first gear 71 is rotatably set on the heat dissipation plate 2 and is located inside the cabinet frame 1; the fixed block 72 is set on the heat dissipation plate 2, and the fixed block 72 has a slide groove; the slider 73 is slidably set in the slide groove, and the two opposite side walls of the slider 73 are respectively provided with a first rack 731 and a second rack, and the first rack 731 is meshed with the first gear 71; the second gear is rotatably set inside the fixed block 72 and meshed with the second rack; the rotating member 74 is coaxially connected with the second gear, and the rotating member 74 can extend out of the heat dissipation plate 2 and can abut against the cabinet frame 1. It can be understood that the slider 73 can be driven to slide during the rotation of the first gear 71, and the rotating member 74 can be driven to rotate under the action of the second rack and the second gear, so that the rotating member 74 can be switched between a locked state and an unlocked state. When the rotating member 74 is in a locked state, the rotating member 74 can abut against the cabinet frame 1, thereby preventing the heat sink 2 from being opened. After rotation, the rotating member 74 can be separated from the cabinet frame 1, thereby enabling the rotating member 74 to switch from a locked state to an unlocked state.

[0055] It should be noted that the first gear 71 is coaxially connected with a lock core, and the lock core can penetrate the heat sink 2 so that the staff can open the heat sink 2 from the outside.

[0056] Among them, a fixed block 72, a slider 73, a second gear, and a rotating member 74 form a set of locking components. The locking structure 7 is provided with multiple sets of locking components along the height direction, and two adjacent sliders 73 are connected by a connecting rod 75. It can be understood that when the first gear 71 rotates, it can drive the slider 73 to slide, and under the action of the connecting rod 75, all sliders 73 can move in the same direction, so that multiple rotating members 74 can be rotated synchronously. In addition, multiple sets of locking components can strengthen the connection strength between the heat sink 2 and the cabinet frame 1.

[0057] Furthermore, the locking assembly further includes a protrusion 77, which is disposed on the cabinet frame 1. The rotating member 74 can abut against the protrusion 77 after rotation, so that the rotating member 74 can be in a locked state. The setting of the protrusion 77 can prevent a gap from existing between the heat sink 2 and the cabinet frame 1 when the rotating member 74 is in a locked state. The thickness of the protrusion 77 is determined according to actual working conditions and is not specifically limited here.

[0058] In addition, the locking assembly also includes a rotating wheel 76; the rotating wheel 76 is arranged at the end of the rotating member 74 away from the second gear, and the rotating wheel 76 can abut against the protrusion 77 under the action of the rotating member 74. The setting of the rotating wheel 76 can reduce the friction between the rotating member 74 and the protrusion 77, thereby increasing the service life of the locking assembly.

[0059] When installing the transformer body, due to the heavy weight of the transformer body, it is not convenient to open the heat dissipation plate 2 for installation. In this embodiment, a skylight for placing the transformer body is provided on the top plate 3, and a mounting plate 8 is detachably provided on the skylight. It can be understood that when installing the transformer body, first remove the mounting plate 8, use a crane or other device to drop the transformer body from the skylight, and after installation, set the mounting plate 8 on the skylight again.

[0060] After the transformer body is installed, the position of the transformer needs to be adjusted. In this embodiment, jacks 41 are evenly distributed on the bottom plate 4. It can be understood that the jacks 41 are adapted to the fork walls of the forklift, so as to facilitate adjusting the position of the transformer by using the forklift.

[0061] Furthermore, to facilitate the wiring of the wires of the transformer body, wire holes are provided at the top of the jacks 41, and the wire holes are communicated with the inside of the transformer equipment cabinet, so as to facilitate connecting the wires to external operating components.

[0062] Based on the above, in this embodiment, a transformer is also proposed, which includes a transformer body and the above-mentioned transformer equipment cabinet, and the transformer body is arranged inside the transformer equipment cabinet. It can be understood that under the action of the transformer equipment cabinet, damage to the transformer body caused by electrical reasons due to rain can be avoided, thereby improving the safety performance of the transformer.

[0063] Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
