Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a solid insulation ring network cabinet. Background Art

[0002] Solid insulation ring main unit is a ring main unit that uses solid insulation material as the main insulation medium. The vacuum interrupter and its conductive connection, disconnector, grounding switch, main bus, branch bus and other main conductive circuits are wrapped and packaged with solid insulation medium to form one or more modules with certain functions, which can be combined or expanded again and have full insulation and full sealing performance. The module surface accessible to people is coated with a conductive or semi-conductive shielding layer and can be directly and reliably grounded.

[0003] The announcement number in the existing public technology is: CN216529883U. A solid insulated ring network cabinet includes a ring network cabinet body, a cabinet door is arranged at the front end of the ring network cabinet body, a rain shield mechanism and a drying mechanism are arranged on the top of the ring network cabinet body, and the rain shield mechanism includes a baffle, and a rectangular plate is arranged inside the baffle. The solid insulated ring network cabinet moves the fixed rod outward, manually pulls the frame plate outward, slides in the movable groove opened in the inner end of the frame plate and the fixed ring, so that several groups of frame plates are fully extended, and after the rain shield cloth fixed to the frame plate is unfolded, the maintenance worker is shielded from rain. When the maintenance is completed, the frame plate drives the rain shield cloth to be pushed back to a distance, and then the movable plate is pushed to bring the fixed rod back to the inside of the baffle. By separating the rain shield cloth from the ring network cabinet body, the rainwater adhering to the upper end of the rain shield cloth is isolated from the ring network cabinet body, and the circuit instruments inside the ring network cabinet body are waterproofed.

[0004] However, the above patent still has certain disadvantages when in use: although the rain above the operator can be shielded by unfolding the rain shield, the rain around the operator is not effectively handled. When performing maintenance on rainy days, rainwater can easily enter the cabinet with the flow of external air and cause damage to the internal circuit. At this time, not only is the rain shielding effect not ideal, but the intrusion of rainwater also increases the probability of electric shock to personnel. The operation safety is not high enough, and the overall use effect is not very good.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0029] According to an embodiment of the utility model, a solid insulation ring main unit is provided.

[0030] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 As shown, a solid insulated ring network cabinet according to an embodiment of the utility model comprises a solid insulated ring network cabinet body 1 and an annular baffle 6, annular baffles 6 are symmetrically welded at both ends of one side surface of the solid insulated ring network cabinet body 1, storage strips 9 are symmetrically installed between the annular baffles 6 and on both sides of the surface of the solid insulated ring network cabinet body 1, storage rollers 7 are rotatably connected to the internal position of the storage strips 9, and waterproof cloths 3 are wound and connected to the surface of the storage rollers 7, support strips 2 are fixedly installed between the waterproof cloths 3, a fixing strip 4 is fixedly installed at the front end position of the waterproof cloth 3, and sliders 10 are installed at the bottom position of the fixing strip 4 and the bottom position of the support strip 2, and a guide groove 12 for sliding of the slider 10 is opened around the outermost position of the surface of the annular baffle 6, and the storage strips 9 are arranged at both sides of the solid insulated ring network cabinet body 1 and the two are independently arranged, and there is a certain distance between them and the installation cavity 11, so that water droplets on the surface of the waterproof cloth 3 that are re-stored after use in rainy days can be prevented from entering the interior of the installation cavity 11, thereby avoiding affecting the internal circuit and the safety of the maintenance personnel.

[0031] In one embodiment, a magnetic strip 5 is installed on the surface of the fixing strip 4. The magnetic strip 5 is provided to ensure that the fixing strip 4 can be attached together during use through magnetic adsorption, thereby ensuring rainproof sealing and improving the overall rainproof effect.

[0032] In one embodiment, one end of the storage roller 7 passes through one side of the annular baffle 6 and is connected to the knob 8. The storage roller 7 is provided to smoothly re-store the waterproof cloth 3 and the support strip 2 after use, and the knob 8 is provided to facilitate personnel to rotate the storage roller 7.

[0033] In one embodiment, the fixing bar 4 and the supporting bar 2 are both made of metal material, and the outer surfaces are wrapped with insulating rubber. The metal material is used to ensure the strength and service life of both, and the insulating rubber wrapping is used to improve insulation and avoid electric shock.

[0034] In one embodiment, a cabinet door 13 is rotatably connected to the surface of one side of the solid insulation ring network cabinet body 1, and an installation cavity 11 is opened inside the solid insulation ring network cabinet body 1. The installation cavity 11 is provided to facilitate the normal installation of equipment in the solid insulation ring network cabinet body 1.

[0035] In one embodiment, the rotation radius of the cabinet door 13 is smaller than the radius of the annular baffle 6. The relationship between the radii is set to prevent the cabinet door 13 from being affected by the annular baffle 6 when opening and thus being unable to open smoothly, thereby ensuring that the structure can be used normally.

[0036] In one embodiment, a groove is provided on the surface of the storage bar 9 for storing the support bar 2 and the waterproof cloth 3 . The arrangement of the groove facilitates the movement of the support bar 2 and the waterproof cloth 3 .

[0037] In one embodiment, the size of the groove on the surface of the storage strip 9 is smaller than that of the fixing strip 4. The size of the fixing strip 4 is set to ensure that the waterproof cloth 3 can fit on the surface of the storage strip 9 after being stored, thereby making it convenient for subsequent personnel to pull it again for use, and avoiding being stuck in the groove on the surface of the storage strip 9, which makes it impossible for subsequent personnel to use it smoothly.

[0038] Working principle: In actual use, the electrical equipment can be normally installed inside the solid insulated ring network cabinet body 1 through the installation cavity 11. When it is necessary to maintain the internal equipment on rainy days later, the personnel can stand on the annular baffle 6 below, and then pull the fixing bars 4 on both sides. At this time, the fixing bars 4 will move to the middle position, thereby driving the waterproof cloth 3 and the support bars 2 to move to the middle. At this time, as the pulling distance gradually increases, the unfolding area of ​​the waterproof cloth 3 also increases accordingly. When the two groups of fixing bars 4 are close to each other and fit together, they can fully surround the outer position of the annular baffle 6 and form a cylindrical structure with the upper and lower groups of annular baffles 6. At this time, the personnel can be fully wrapped and protected, which can effectively avoid the intrusion of rainwater. Not only does it expand the overall rainproof area and improve the rainproof effect, but also after the rainwater no longer invades, it can also avoid moisture adhering to the internal circuit to cause damage to the equipment and electric shock to personnel, which can effectively improve the overall maintenance safety and facilitate better use. The device as a whole has the advantages of large protection area, good rainproof effect and high safety of operation in the rain.
