Description

Technical Field

[0001] The present invention relates to the technical field of switchgear, and more particularly to an armored removable AC metal-enclosed switchgear. Background Art

[0002] Armored removable AC metal-enclosed switchgear occupies an important position in modern power systems due to its modular design and high sealing characteristics. The modular design allows each functional unit of the equipment to be independently manufactured, assembled and maintained, greatly improving production and maintenance efficiency; the high sealing effectively protects the internal electrical components from external environmental interference, ensuring stable operation of the equipment.

[0003] However, in terms of cable installation structure, combined with its modular and high sealing characteristics, there are still many problems that need to be solved. For example: 1. Conflict between traditional cable wiring and module layout: modular design makes the internal space layout of the equipment compact, but the existing cable wiring method fails to fully combine the characteristics of module layout. When the cable passes through different modules, there is often a lack of reasonable channel planning, resulting in messy cable laying, which not only affects the appearance, but also may damage the outer skin due to friction between the cable and the edge of the module, causing safety hazards. Moreover, messy wiring is not conducive to the replacement and maintenance of the module in the later stage. Once a module fails and needs to be replaced, the complex cable wiring will increase the difficulty of disassembly and reinstallation. 2. The problem of easy failure of traditional cable introduction seal: in order to ensure the high sealing of the equipment, the sealing structure after the cable is installed requires a relatively tight installation structure, but the current commonly used sealing method, such as sealing the cable through a rubber ring after simple constraint, is very easy to loosen during long-term use due to factors such as temperature changes and cable vibration, resulting in a decrease in sealing performance. In view of this, we propose an armored removable AC metal-enclosed switchgear. Summary of the invention

It is worth noting that the elastic properties of the first springs 308 are different. When the parts in the deformation assembly 4 move upward, the slider on the support bar 309 is moved to the top of one side of the support rod 306 through each first spring 308, so as to avoid elastic fatigue of the first spring 308 The third slider is fixedly connected to the first spring 308, and the driving module 6 is arranged on the left side of the mounting plate 2. The present invention uses the adjustment mechanism 3 to make the cable branches have two distribution effects: linear array variable pitch arrangement and fan-shaped array arrangement. When the cable branches are arranged in a linear array variable pitch, the direction of the cable branches can be more clearly planned, and the spacing between the cable branches can be adjusted to maintain the appropriate distance between the cable branches. The linear array variable pitch arrangement can adapt to different installation spaces. When the cable branches are arranged in a fan-shaped array, the combing component 5 can be used to spirally wind the cable branches, so that they have a more reasonable distribution in space and increase the stability of the overall structure.

When the linear array is arranged with variable pitch, the first motor 602 is operated through an external circuit mechanism. The first motor 602 drives the first driving gear 603 to rotate, and drives the first gear 605 to rotate through the first transmission belt 606, so that the first screw rod 604 rotates. The first threaded frame 607 moves downward on the first screw rod 604 through a threaded connection. When the guide plate 304 moves downward, it slides inside the slide groove 305 through the limit block 3061, exerting a force on the plurality of support rods 306, and the support rods 306 are moved between the plurality of first The pneumatic slider 5053 slides on the slide bar 302 to realize the variable pitch arrangement of the first slide bar 302 in a linear array, and then the pneumatic slider 5053 slides inside the arc groove 5051 through an external driving mechanism, so that the two metal plates 5054 are opened to both sides, and the plurality of stringing blocks 5056 move outward, and a force is applied to the stringing block 5056 through the second spring 50571, and the first abutment plate 5055 and the second abutment block 5057 are abutted against the stringing block 5056 on both sides, so that the plurality of stringing blocks 5056 are arranged in a linear array. At the same time, the two metal plates 5054 are in a straight plate state through their own elastic characteristics, so that the pulley 50561 on the stringing block 5056 is in active contact with the upper surface of the metal plate 5054, thereby realizing the stringing block 50 56 corresponds to the position of the bearing hole 3091. When the cable branches are arranged in a fan shape, the position of the support bar 309 is adjusted by the adjustment mechanism 3 so that the support bar 309 corresponds to the position of the through hole 409, and then the second motor 402 is operated by the external circuit mechanism. The second motor 402 drives the second driving gear 403 and drives the second gear 405 through the second transmission belt 406, so that the second screw rod 404 rotates, and the deformation plate 408 moves downward on the second screw rod 404 through the second threaded frame 407, so that the support bar 309 moves to the inside of the through hole 409, and then continues to move downward. The support bar 309 moves downward on the limit rod 307 through the slider, so that the bearing holes 3091 on the support bar 309 are arranged in a fan-shaped array. During winding, the third motor 503 is operated through an external circuit mechanism, and the third motor 503 operates through one of the unidirectional rotating structures to operate the gear plate 507, and the third gear 508 is rotated through the gear meshing transmission, and the third gear 508 is meshed and connected with the tooth plate 5011, so that the support frame 502 moves downward through the limit plate 501. After the adjustment is completed, the pneumatic slider 5053 is slid on the arc-shaped slide rod 5052 through the external driving structure, and the two metal plates 5054 are brought closer to the middle, wherein a plurality of stringing blocks 5056 are gathered to the middle through the metal plate 5054 to form an irregular circle. When the pneumatic slider 5053 moves to the vertex, the metal plate 5054 wraps the plurality of stringing blocks 5056 and deforms.The pulley 50561 is in active contact with the inner side of the two metal plates 5054, and then the third motor 503 is operated through the external circuit mechanism, and the transmission wheel 506 is rotated through another unidirectional rotation structure, and the surface of the transmission wheel 506 is in active contact with the transmission cylinder 504, so that the transmission cylinder 504 rotates, and then drives a number of stringing blocks 5056 to rotate, and the cable is spirally wound. After the arrangement is completed, the threading hole is sealed with sealant.
