Specific embodiments

[0026] The present utility model discloses a ring main unit. The following combines with the preferred embodiment (Embodiment 1) and refers to the Figures 1-9 drawings to further describe the specific embodiments of the present utility model.

[0027] Referring to the Figures 1 to 9 drawings, Figures 1 to 5 which respectively show the ring main unit from different perspectives, Figures 6 to 9 and respectively show the overall structure or partial structure of the base of the ring main unit.

[0028] Embodiment 1 (the suspended part 222 of the support plate is fixedly connected to the base bottom plate 230).

[0029] Preferably, the ring main unit includes a main body 100 of the ring main unit. Voltage transformers and other ring main unit devices (the voltage transformer can adopt the existing technology) are built in the main body 100 of the ring main unit. The ring main unit further includes a base 200 of the ring main unit. There is a base gap 201 between the base 200 of the ring main unit and the main body 100 of the ring main unit, so that voltage transformers and other ring main unit devices built in the main body 100 of the ring main unit are protected from the threat of water intrusion from bottom to top (as an example, for a ring main unit installed outdoors, during or after a heavy rain, the surrounding environment is prone to water accumulation, causing the threat of water intrusion from bottom to top), thereby ensuring the continuous and stable operation of voltage transformers and other ring main unit devices. Among them:

[0030] The main body 100 of the ring main unit includes a cabinet body 110, and voltage transformers and other ring main unit devices are built in the cabinet body 110;

The base main board 210 is provided with a main board body part 211 and a main board extension part 212 integrally formed with the main board body part 211. The main board extension part 212 partially extends into the cabinet body 110. The base support board 220 is located between the main board body part 211 and the cabinet body 110, and the base support board 220 is fixedly connected to the cabinet body 110 so that the base main board 210 and the base support board 220 jointly support the cabinet body 110;

[0032] The base 200 of the ring main unit cabinet further includes a base bottom board 230. The base support board 220 is provided with a support board main body part 221 and a support board overhanging part 222. One end of the support board overhanging part 222 is integrally formed with the support board main body part 221, and the other end of the support board overhanging part 222 supports on the base bottom board 230. The support board overhanging part 222 is fixedly connected to the base bottom board 230, so that the base main board 210 further divides the base gap 201 into an open space between the base main board 210 and the cabinet body 110, and an open space between the base main board 210 and the base bottom board 230. The two open spaces are both interconnected and relatively separated, better realizing the overall ventilation effect, and at the same time helping to quickly dissipate the heat inside the cabinet 110 to the surrounding environment.

[0033] Among them, the base 200 of the ring main unit cabinet further includes a drying net 250 and (two) drying net guard plates 240.

The main board enclosing part 213 is located on the side of the main board body part 211 away from the main board extension part 212, so that the main board enclosing part 213 and the main board extension part 212 are respectively on different sides of the main board body part 211, and the main board enclosing part 213 is integrally formed with the main board body part 211.

[0036] Among them, the base bottom board 230 is provided with a bottom board main body part 231 and a bottom board contraction part 232 integrally formed with the bottom board main body part 231, so that the bottom board main body part 231 and the bottom board contraction part 232 enclose an open space.

[0037] Among them, the cross-sectional area of the upper edge of the bottom plate contraction part 232 is larger than that of the bottom plate main body part 231, so that the base bottom plate 230 presents a shape with a larger upper part and a smaller lower part, which helps to prevent accumulated water from overflowing into the base bottom plate 230.

[0038] Embodiment 2 (the support plate suspension part 222 is slidably connected to the base bottom plate 230).
