Description

Technical Field

[0001] This utility model belongs to the field of ring main unit technology, and in particular relates to a side-expanded ring main unit cabinet structure. Background Technology

[0002] A ring main unit (RNB) is a switching device used in power distribution systems. It connects electrical energy from high-voltage transmission lines to medium- and low-voltage distribution lines, thereby meeting the power distribution needs of the power system. In recent years, with the rapid development of the power industry, RNBs have become an indispensable piece of equipment. Considering production costs and ease of installation and use, most mainstream RNB manufacturers on the market currently adopt the side-expansion and paralleling method. To meet the requirements for side-expansion and paralleling distances, traditional gas-box structure designs often use a gas-box width that is generally smaller than the width of the mechanism compartment and cable compartment. This type of structure results in gaps between the paralleling cabinets, leading to a noticeably poorer appearance. Utility Model Content

[0003] In view of this, the present invention aims to propose a side-expanding ring main unit cabinet structure to solve at least one of the problems existing in the prior art, thereby avoiding the disadvantages of small gas box space and poor appearance of the existing side-expanding ring main unit cabinet.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A side-expanded ring main unit cabinet structure includes a right side plate of the gas box, a left side plate of the gas box, a side outlet pressure plate, a right side plate of the mechanism chamber, a left side plate of the mechanism chamber, a right side plate of the cable chamber, and a left side plate of the cable chamber. The right side plate and the left side plate of the gas box are symmetrically arranged. The right side plate of the mechanism chamber and the right side plate of the cable chamber are respectively installed on one side of the right side plate of the gas box, and the right side plate of the mechanism chamber is located above the right side plate of the cable chamber. The left side plate of the mechanism chamber and the left side plate of the cable chamber are respectively installed on one side of the left side plate of the gas box, and the left side plate of the mechanism chamber is located above the left side plate of the cable chamber. A side outlet pressure plate is also installed above the right side plate and the left side plate of the gas box, and the two side outlet pressure plates are symmetrically arranged. The right side plate, the left side plate of the gas box, the side outlet pressure plate, the right side plate of the mechanism chamber, the left side plate of the mechanism chamber, the right side plate of the cable chamber, and the left side plate of the cable chamber constitute the ring main unit cabinet structure.

[0006] Furthermore, it also includes a cabinet connection plate, which is used to connect the cabinet structures of two ring main units.

[0007] Furthermore, both the right side plate and the left side plate of the air box are provided with concave bends, which are used to install the side expansion sleeves.

[0008] Furthermore, the height of the concave bend is 13mm.

[0009] Furthermore, the concave bend is a cuboid groove structure.

[0010] Furthermore, the surfaces of the right side plate and left side plate of the air box, except for the concave bends, are flush with the surfaces of the right side plate of the mechanism chamber, the right side plate of the cable chamber, the left side plate of the mechanism chamber, and the left side plate of the cable chamber, respectively.

[0011] Furthermore, the side-mounted pressure plate is also provided with several clearance holes for installing the side-expanding sleeve.

[0012] Furthermore, the right side plate of the air box, the left side plate of the air box, the side outlet pressure plate, the right side plate of the mechanism chamber, the left side plate of the mechanism chamber, the right side plate of the cable chamber, and the left side plate of the cable chamber are all metal plates.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 6 As shown, a side-expanded ring main unit cabinet structure includes a right side plate 1 of the gas box, a left side plate 2 of the gas box, a side outlet pressure plate 3, a parallel cabinet connection plate 4, a right side plate 5 of the mechanism chamber, a left side plate 6 of the mechanism chamber, a right side plate 7 of the cable chamber, and a left side plate 8 of the cable chamber. After the ring main units are paralleled, the right side plate 1 of the gas box of the left ring main unit and the left side plate 2 of the gas box of the right ring main unit are tightly fitted together without any parallel cabinet gaps.

[0029] The structure of this side-expanded ring main unit meets the requirements of the side-expanded sleeve and cabinet spacing. It not only enhances the strength of the side-expanded sleeve of the gas box side plate, but also increases the overall internal space of the gas box. At the same time, it achieves seamlessness between gas boxes after cabinet consolidation, and the front and back of the cabinet are neat and beautiful.

[0030] In a preferred embodiment of this utility model, the installation points of the side expansion sleeves on the right side plate 1 and the left side plate 2 of the gas box are characterized by concave bending 11, and a side pressure plate 3 is welded to the outside to increase the sheet metal strength at the junction of the cabinets, thereby reducing the risk of gas box leakage. Figure 4 As shown, two side expansion sleeves are symmetrically installed on the top inner side of the side expansion ring network cabinet structure of this application. One end of each side expansion sleeve passes through the concave bend 11 and is connected to the side outlet pressure plate 3. The side outlet pressure plate 3 is also provided with several clearance holes for installing the side expansion sleeves.

[0031] In a preferred embodiment of this utility model, the side expansion sleeve installation locations of the right side plate 1 and the left side plate 2 of the gas box adopt an inward concave bend 11, with a height of 13mm (to account for gas box inflation deformation, leaving 3mm for gas box side plate deformation), meeting the State Grid standard requirement of a parallel cabinet distance of 32mm. Except for the inward concave bend design at the side expansion sleeve installation locations to meet the parallel cabinet distance requirement, the remaining parts of the right side plate 1 and the left side plate 2 of the gas box are flush with the right side plate 5 of the mechanism room, the right side plate 7 of the cable room, the left side plate 6 of the mechanism room, and the left side plate 8 of the cable room. Compared with the traditional ring main unit gas box structure design, this design increases the space on both sides of the gas box by 10.5mm (excluding sheet metal thickness), ensuring ample space for the arrangement of all live parts within the gas box and increasing the electrical insulation distance.

[0032] In a preferred embodiment of this utility model, the right side plate 1 of the gas box, the left side plate 2 of the gas box, the side outlet pressure plate 3, the right side plate 5 of the mechanism chamber, the left side plate 6 of the mechanism chamber, the right side plate 7 of the cable chamber, and the left side plate 8 of the cable chamber are all metal plates. Except for the side expansion sleeve installation area which adopts an inward bending design to meet the cabinet paralleling distance, the other parts of the right side plate 1 and the left side plate 2 of the gas box are flush with the right side plate 5 of the mechanism chamber, the right side plate 7 of the cable chamber, the left side plate 6 of the mechanism chamber, and the left side plate 8 of the cable chamber. Compared with the traditional gas box structure design of the ring main unit, the ring main unit has no paralleling gap at the rear of the gas box after the paralleling is completed, achieving a neat and beautiful appearance.

[0033] The beneficial effects of this utility model are: it enhances the strength of the side expansion sleeve and reduces the risk of gas box leakage; it increases the overall internal space of the gas box and increases the insulation distance between each live part; after the cabinet is connected, there are no gaps between the gas boxes, and the cabinet is neat and beautiful from front to back.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
