[0035] The following is combined with Figures 1-5 This application is described in further detail.
[0036] An embodiment of the present application discloses a ring main unit.
[0037] Reference Figure 1 The ring main unit includes a cabinet body 1 and two cabinet doors 2. The cabinet body 1 is arranged in a rectangular shape, and one side of the cabinet body 1 is arranged with an opening. The two cabinet doors 2 are arranged in a rectangular plate shape and are located at the opening of the cabinet body 1. The sides of the two cabinet doors 2 that are away from each other are connected to the cabinet door 2 by a hinge, and the cabinet body 1 is opened or closed by rotating the two cabinet doors 2.
[0038] Reference Figure 2 , wherein the bottom of the cabinet body 1 at the opening is fixedly connected with two water retaining bars 11 by bolts, the length direction of the two water retaining bars 11 is arranged along the length direction of the cabinet body 1, and the two water retaining bars 11 are arranged at intervals along the width direction of the cabinet body 1. The two water retaining bars 11 have a certain height, so that a drainage groove 12 is formed between the two water retaining bars 11 and the bottom of the cabinet body 1 to collect rainwater entering from the gaps of the two cabinet doors 2. At the same time, drainage holes 13 are opened on both sides of the cabinet body 1, and the two ends of the drainage groove 12 are respectively connected to the two drainage holes 13 to realize the drainage of rainwater in the drainage groove 12.
[0039] In actual application, when the ring main unit is in use, the two cabinet doors 2 are rotated to close the cabinet body 1. When rainwater enters the cabinet body 1 from the gap between the two cabinet doors 2, the rainwater can be collected in the drainage groove 12 formed between the two water retaining strips 11 and the cabinet body 1, and the two ends of the drainage groove 12 are respectively connected with the drainage holes 13 on both sides of the cabinet body 1, so as to facilitate the discharge of rainwater from the drainage groove 12 and avoid rainwater accumulation in the cabinet body 1 as much as possible, thereby ensuring the normal operation of the ring main unit.
[0040] Reference Figure 1 andFigure 2 , in some embodiments, the ring main unit further includes two water plugs 3. The two water plugs 3 are respectively inserted tightly into the two drain holes 13, and the water plugs 3 are located outside the cabinet body 1. During the use of the power distribution cabinet, the two water plugs 3 are inserted tightly into the two drain holes 13 to block the drain holes 13, and try to prevent rainwater from entering the cabinet body 1 through the drain holes 13. When it is necessary to drain the drain tank 12, the rainwater in the drain tank 12 can be discharged by pulling out the water plugs 3, and the operation is simple and convenient.
[0041] Refer to Figure 1 , in some embodiments, the ring main unit further includes a rain shield 4. The rain shield 4 is fixedly connected to the upper end of the cabinet body 1, and one end of the rain shield 4 located at the cabinet door 2 protrudes from the cabinet body 1 to block rainwater, which can effectively reduce the contact between rainwater and the two cabinet doors 2, thereby reducing the entry of rainwater into the cabinet body 1 through the gaps between the two cabinet doors 2.
[0042] In some embodiments, the upper side of the rain shield 4 is inclined. Specifically, the upper side of the rain shield 4 near the cabinet door 2 is lower than the upper side of the rain shield 4 far from the cabinet door 2. Under the action of gravity, the blocked rainwater is guided to try to prevent the rainwater from flowing from the rain shield 4 to between the two cabinet doors 2, thereby further reducing the entry of rainwater into the cabinet body 1 through the gaps between the two cabinet doors 2.
[0043] Refer to Figure 3 , in some embodiments, a plurality of first heat dissipation holes 41 are spaced apart along the circumferential direction of the lower side of the rain shield 4. The first heat dissipation holes 41 are arranged in a strip shape, and a plurality of second heat dissipation holes 42 are evenly opened at the upper end of the rain shield 4 located at the cabinet body 1. The plurality of second heat dissipation holes 42 are communicated with the inside of the cabinet body 1, and at the same time, the plurality of second heat dissipation holes 42 are communicated with the plurality of first heat dissipation holes 41 to improve the heat dissipation effect of the cabinet body 1, and try to avoid the situation that the electronic components in the cabinet body 1 cannot dissipate heat in time, thereby ensuring the normal operation of the ring main unit.
[0044] Refer to Figure 4 and Figure 5 , in some embodiments, a first rain shield ring 43 is fixedly connected along the circumferential direction of the rain shield 4. The first rain shield ring 43 shields the plurality of first heat dissipation holes 41. In heavy rain weather, rainwater is easily splashed and enters the cabinet body 1 through the first heat dissipation holes 41 and the second heat dissipation holes 42. The first rain shield ring 43 blocks the splashed rainwater and tries to prevent the rainwater from entering the cabinet body 1 to ensure the waterproof effect of the rain shield 4, thereby ensuring the normal operation of the ring main unit.
[0045] In some embodiments, a second rain shield ring 44 is fixedly connected along the circumferential direction of the rain shield 4. The second rain shield ring 44 is located above the first rain shield ring 43 to block the rainwater not blocked by the first rain shield ring 43 and further improve the waterproof effect of the rain shield 4.
[0046] In some embodiments, the first rain shield ring 43 and the second rain shield ring 44 are arranged in a staggered manner, so that the first rain shield ring 43 and the second rain shield ring 44 cooperate to more fully block rainwater, thereby further improving the waterproof effect of the rain shield 4.
[0047] The implementation principle of this embodiment is as follows: in practical applications, when the ring main unit is in use, the two cabinet doors 2 are rotated to close the cabinet body 1. Among them, when rainwater enters the cabinet body 1 from the gap between the two cabinet doors 2, the rainwater can be collected in the drainage groove 12 formed between the two water blocking strips 11 and the cabinet body 1, and both ends of the drainage groove 12 are respectively communicated with the drainage holes 13 on both sides of the cabinet body 1, so as to facilitate the discharge of the rainwater in the drainage groove 12 and avoid rainwater accumulation in the cabinet body 1 as much as possible, thereby ensuring the normal operation of the ring main unit.
[0048] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered by the protection scope of this application.
