Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinet equipment, in particular to a novel C-GIS cabinet and screen connecting guide structure. Background Art

[0002] In recent years, with the rapid development of social and economic construction, the complexity of various engineering construction projects has gradually increased. Miniaturized, intelligent and maintenance-free switchgear products are becoming more and more popular in today's society. Switchgear manufacturers at home and abroad have vigorously developed C-GIS equipment, commonly known as "inflatable cabinet". C-GIS is to install high-voltage components such as vacuum circuit breakers, three-position disconnectors, busbars and mutual inductors in upper and lower isolation chambers respectively. The isolation chambers are filled with SF6 gas as the insulating medium, which greatly reduces the external dimensions of the cabinet, thereby realizing the miniaturization of the cabinet and operational reliability.

[0003] The existing Chinese patent document CN201717546U discloses a busbar connection device, which includes an intermediate insulating sleeve, two flange assemblies and two cabinet insulating seats. The two ends of the intermediate insulating sleeve are respectively inserted into the insulating seats of the two cabinets. Each flange assembly includes two half flanges that are symmetrical and assembled into a first integral flange and a second integral flange. The first integral flange and the second integral flange are both sleeved on the intermediate insulating sleeve and can be radially positioned relative to each other. The flange assembly forms a pressure ring for pressing the insulating sleeve. The two flange assemblies respectively position the two ends of the intermediate insulating sleeve in the two cabinet insulating seats and fix them on the two cabinet insulating seats. The busbar is connected by a connector that is inserted into the insulating sleeve and connected to the insulating seat, thereby achieving connection.

[0004] However, the above patent has certain defects when in use. C-GIS is usually placed in multiple places for use, and there is no corresponding connection and fixing device between the multiple C-GIS, which causes the multiple C-GIS to be easily displaced individually under external force factors, which can easily cause pulling on the line, thereby affecting the line connection.

[0005] Therefore, a new C-GIS cabinet and screen guide structure is proposed to solve the above problems. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a novel C-GIS cabinet and screen connecting guide structure.

[0007] The utility model is implemented by the following technical solutions:

[0008] A novel C-GIS cabinet and screen guide structure comprises a top cover, wherein the left and right sides of the top cover are symmetrically provided with lifting U-shaped grooves, and the lifting U-shaped grooves are welded to the upper surface of the top cover;

[0009] There are guiding holes provided in the lifting U-shaped groove on the left side. There are two such guiding holes. On the right side wall of the lifting U-shaped groove on the right side, there are guiding columns. There are two such guiding columns. When two C-GIS cabinets are combined, the guiding columns are inserted into the guiding holes;

[0010] A limiting device is provided inside the guiding column, and the limiting device is used for the limiting and fixing of the guiding column in the guiding hole.

[0011] The limiting device includes a cavity and a limiting channel. The cavity is arranged inside the guiding column. The limiting channel is arranged on the surface of the guiding column and is connected to the cavity. Inside the cavity, there is a sliding plate. On the upper surface of the sliding plate, there is a connecting column, and the upper end of the connecting column extends out of the limiting channel;

[0012] On the lower surface of the sliding plate, there is a guiding rod. A spring is sleeved on the guiding rod. One end of the spring is fixed at the bottom of the cavity, and the other end is fixed on the lower surface of the sliding plate.

[0013] At the top of the connecting column, there is a ball, and the ball can roll freely inside the connecting column.

[0014] At the center of the top cover, there is a top skylight, and a sealing ring is provided between the top skylight and the top cover.

[0015] At the top end of the top cover, there is a front reinforcing rib, and at the bottom of the top cover, there is a rear reinforcing rib. The front reinforcing rib and the rear reinforcing rib are fixedly welded to the top cover.

[0016] The utility model has the following beneficial effects compared with the prior art:

[0017] 1. By providing guiding columns and guiding holes on the top cover, and a limiting device is arranged inside the guiding column. The guiding columns play a guiding role. When two cabinets are combined, the guiding columns are accurately inserted into the guiding holes. When the guiding columns penetrate into the guiding holes and move to the limiting grooves in the guiding holes, then the limiting device is activated. Through the coordinated action of the internal sliding plate, spring and ball, the stable limitation of the guiding columns in the guiding holes is realized, ensuring no relative displacement between the cabinets;

[0018] 2. By providing reinforcing ribs and skylights on the top cover, the reinforcing ribs are welded to the top cover, making the overall structure more stable and reliable, capable of withstanding greater external loads, prolonging the service life of the equipment. And the design of the top skylight makes the maintenance and overhaul of the internal components of the equipment more convenient and fast, reducing the maintenance cost. Description of the Drawings

Specific embodiments

[0023] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0024] The following further describes the present utility model with reference to the drawings.

[0025] As Figures 1 to 3 shown, a novel C-GIS cabinet connection and screen guiding structure includes a top cover 1. Lifting U-shaped grooves 2 are symmetrically arranged on the left and right sides of the top cover 1, and the lifting U-shaped grooves 2 are welded on the upper surface of the top cover 1;

[0026] Guide holes 5 are provided in the left lifting U-shaped groove 2, two guide holes 5 are provided, and guide posts 7 are provided on the right side wall of the right lifting U-shaped groove 2, two guide posts 7 are provided. When two C-GIS cabinets are combined, the guide posts 7 are inserted into the guide holes 5; a limiting groove is reserved inside the guide holes 5.

[0027] A limiting device 8 is arranged inside the guide post 7, and the limiting device 8 is used for the limiting and fixing of the guide post 7 in the guide hole 5.

[0028] The limiting device 8 includes a cavity 83 and a limiting channel 86. The cavity 83 is arranged inside the guide post 7, the limiting channel 86 is arranged on the surface of the guide post 7 and is communicated with the cavity 83. A sliding plate 82 is arranged inside the cavity 83, a connecting column 87 is arranged on the upper surface of the sliding plate 82, and the upper end of the connecting column 87 extends out of the limiting channel 86;

[0029] A guide rod 85 is arranged on the lower surface of the sliding plate 82, a spring 84 is sleeved on the guide rod 85, one end of the spring 84 is fixed at the bottom of the cavity 83, and the other end is fixed on the lower surface of the sliding plate 82.

[0030] The top of the connecting column 87 is provided with a ball 81 which can roll freely within the connecting column 87. When the cabinet combination operation starts, the design of the ball 81 reduces the friction and resistance during the snapping-in process, ensuring the smooth progress of the limiting action.

[0031] A top skylight 6 is provided at the center of the top cover 1, and a sealing ring is provided between the top skylight 6 and the top cover 1. As the core load-bearing component, lifting U-shaped grooves 2 are symmetrically welded to the left and right sides of the upper surface of the top cover 1, facilitating the lifting operation. A top skylight 6 is provided at the center of the top cover 1, facilitating subsequent maintenance and repair, and a high-sealing sealing ring is provided between the skylight and the top cover 1 to ensure that the internal environment of the equipment is not affected by the outside.

[0032] To enhance the rigidity and stability of the top cover 1, front reinforcing ribs 3 are provided at the top end of the top cover 1, and rear reinforcing ribs 4 are provided at the bottom of the top cover 1. The front reinforcing ribs 3 and the rear reinforcing ribs 4 are fixedly welded to the top cover 1, effectively resisting external loads and preventing deformation.

[0033] The working principle of the present utility model is as follows: When in use, if multiple gas-insulated switchgears need to be combined, ensure that both gas-insulated switchgears are in a movable state and the surrounding environment is suitable for the cabinet combination operation. Push a single gas-insulated switchgear to a predetermined position so that the lifting U-shaped groove 2 on its left side aligns with and approaches the lifting U-shaped groove 2 on the right side of another gas-insulated switchgear. During this process, the left guiding hole 5 of the gas-insulated switchgear gradually approaches the guiding column 7 on the right side of another gas-insulated switchgear. When the guiding column 7 aligns with the guiding hole 5, gently push the gas-insulated switchgear to enable the guiding column 7 to smoothly penetrate into the guiding hole 5.

[0034] As the guiding column 7 penetrates deeper, the limiting device 8 inside it starts to function. Specifically, when the guiding column 7 penetrates into the guiding hole 5 to a certain depth, the limiting device 8 comes into contact with the reserved limiting groove in the guiding hole 5. The connecting column 87 in the limiting device 8 pops outwards under the action of the spring 84, passes through the limiting channel 86 and snaps into the limiting groove of the guiding hole 5 to achieve clamping.

[0035] At this time, through the cooperation of the guiding column 7 and the guiding hole 5 and the fixing action of the limiting device 8 between the two gas-insulated switchgears, the initial cabinet combination connection is achieved. After confirming that the two cabinets are firmly connected, check whether there is looseness or abnormal noise between the guiding column 7 and the guiding hole 5. If it is necessary to further adjust the position of the cabinet, one side of the gas-insulated switchgear can be gently moved to disengage the connecting column 87 from the limiting groove, and then the guiding and limiting operations can be carried out again.

[0036] The above embodiments are only the preferred embodiments of the present utility model and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
