[0002] Low-voltage withdrawable switchgear is widely used in power distribution centers (PCs) and motor control centers (MCCs) in power plants, substations, factories, mines, and high-rise buildings. It serves as a low-voltage complete distribution device for power distribution, centralized motor control, and reactive power compensation in power generation and supply systems with an AC frequency of 50-60Hz, a rated working voltage of 660V and below, and a rated current of 4000A and below.

[0003] When the switch cabinet is in use, there are many devices and cables distributed inside according to the use requirements. These cables are usually tied and positioned by binding ropes and neatly arranged on the inner wall of the switch cabinet. However, since there are many cables, they are stacked. Therefore, each time the equipment is inspected or replaced, the binding ropes need to be removed, replaced and then re-bundled. If the deepest cables need to be inspected, the many cables blocked by the outside need to be removed, which affects the operation of the entire equipment and is time-consuming and labor-intensive.

The first cable clamping rack 401 is hinged to the front of the cable fixing plate 1 by a hinge and can be rotated relative to the cable fixing plate 1, which can facilitate the opening between the first cable clamping rack 401 and the cable fixing plate 1. A number of cable clamping grooves 2 are equidistantly arranged vertically and corresponding to each other on both sides of the top and bottom of the first cable clamping rack 401. Elastic clamps 3 are provided in the cable clamping grooves 2 on the top and bottom of the side of the first cable clamping rack 401 away from the cable fixing plate 1. The installer can clamp the cables to the cable clamps on the side of the first cable clamping rack 401 away from the cable fixing plate 1. The first cable clamp 401 is provided with a plurality of first partitions 402, each of which is fixed to the first cable clamp 401 and a plurality of second partitions 402. The first partitions 402 are provided in a plurality of first ...

Elastic clamps 3 are provided in the cable clamping grooves 2 at the top and bottom of the side of the second cable clamping rack 501 away from the first cable clamping rack 401. The cable clamping grooves 2 on the side of the second cable clamping rack 501 away from the first cable clamping rack 401 can also clamp cables, and can be fixed with the cable fixing The fixed plate 1 and the cables in the first cable clamp 401 are stacked to form a multi-layer cable structure, and the cable clamping groove 2 of the second cable clamp 501 near the side of the first cable clamp 401 can clamp and fix the cables in the first cable clamp 401 when the second cable clamp 501 and the first cable clamp 401 are clamped to each other through the buckle structure; there are two second partitions 502, and the two second partitions 502 are fixedly connected to the interior of the second cable clamp 501 and are symmetrically arranged with the horizontal center line of the second cable clamp 501 as the symmetry axis. The second partitions 502 can compress the cables clamped in the first cable clamp 401 and the second cable clamp 501 and separate them from the outer cables, which can effectively prevent the cables of two adjacent layers from being entangled or intertwined with each other.

[0024] The second cable clamping assembly 5 is hinged on one side away from the first cable clamping assembly 4 with an outer sealing plate 6 that can clamp the cables arranged on the second cable clamping assembly 5. The outer sealing plate 6 includes an outer cable clamping rack 601 and a third partition plate 602.

The snap-on structure includes a snap-on groove 7 and a snap-on 8. The sides of the cable fixing plate 1, the first cable clamping rack 401 and the second cable clamping rack 501 are all provided with a snap-on groove 7. The first cable clamping rack 401, the second cable clamping rack 501 and the outer cable clamping rack 601 are close to the cable fixing plate 1 on the same side and are fixedly connected with a snap-on 8 at the position corresponding to the snap-on groove 7. The snap-on 8 on the first cable clamping rack 401 is buckled into the line The buckle 8 of the second cable clamp 501 is buckled into the corresponding buckle groove 7 on the cable fixing plate 1, and the buckle 8 of the outer cable clamp 601 is buckled into the corresponding buckle groove 7 on the second cable clamp 501. By setting the buckle structure, the two adjacent structures among the cable fixing plate 1, the first cable clamp 401, the second cable clamp 501 and the outer cable clamp 601 can be clamped to each other, so that the cables in any structure can be easily inspected and repaired without removing other cables, thereby ensuring stable operation of the equipment.

[0026] The overall height of the first cable bracket 401 is less than the overall height of the second cable bracket 501, the overall height of the second cable bracket 501 is less than the overall height of the outer cable bracket 601, and the overall height of the outer cable bracket 601 is the same as the overall height of the cable fixing plate 1. Through this design, the first cable bracket 401, the second cable bracket 501 and the outer cable bracket 601 can be staggered with each other, which is convenient for distinguishing cables between different levels, and the first partition 402, the second partition 502 and the third partition 602 can be mutually They are staggered, and the front sides of the first partition 402, the second partition 502 and the third partition 602 are fixedly connected with identification racks for placing identification plates, and the installer can place the corresponding cable information in the identification racks, so that the corresponding target cables can be quickly found during subsequent maintenance; the first cable clamp 401, the second cable clamp 501 and the outer cable clamp 601 are fixedly connected with a buckle plate on one side close to the buckle structure, and the buckle plate can be used to facilitate the outward opening of the corresponding first cable clamp 401, the second cable clamp 501 or the outer cable clamp 601.

[0027] In summary, the cable arrangement structure for installing the low-voltage withdrawable switchgear can be used in the following steps:

[0028] 1. The installer can first press the cables into the cable slots 2 in the cable fixing plate 1. The elastic clamps 3 can play a preliminary clamping role on the cables in the cable slots 2.

[0029] 2. When the cable slots 2 in the cable fixing plate 1 are filled with cables, clamp the first cable clamp 401 to the front of the cable fixing plate 1 through the buckle 8 and the buckle slot 7 to clamp the cables in the cable fixing plate 401.

[0030] 3. Arrange the cables in the cable slots 2 on the front of the first cable bracket 401. When the cable slots 2 in the first cable bracket 401 are full of cables, fasten the second cable bracket 501 to the front of the first cable bracket 401 using the buckles 8 and the buckle slots 7. This secures the cables in the first cable bracket 401.

[0031] 4. Finally, arrange the excess cables in the cable slot 2 on the front of the second cable bracket 501. When the cable slot 2 on the front of the second cable bracket 501 is full of cables, fasten the outer cable bracket 601 to the front of the second cable bracket 501 through the buckle 8 and the buckle slot 7.
