Abstract
Description
Technical Field
[0001] This application relates to the field of electrical equipment cabinet technology, and in particular to a low-voltage withdrawable switch cabinet. Background Technology
[0002] Low-voltage withdrawable switchgear is equipment responsible for power control, protection, conversion, and distribution in low-voltage power supply systems. It mainly consists of busbars, components (including disconnect switches, circuit breakers, fuses, contactors, and thermal relays), instruments, and a cabinet. The cabinet has multiple drawers, each containing modular components. The components inside the drawers are interconnected by wires, and some components also need to be connected to the power supply via wires. To facilitate future maintenance or replacement of modular components, a certain length of wire is usually provided for each component. However, when a drawer contains multiple components, each component requires a pre-existing wire length, which can easily lead to tangling of the wires. Utility Model Content
[0003] To prevent the wires inside the switch cabinet drawer from getting tangled, this application provides a low-voltage withdrawable switch cabinet.
[0004] This application provides a low-voltage withdrawable switchgear, which adopts the following technical solution:
[0005] A low-voltage withdrawable switch cabinet includes a cabinet body and drawers. The drawers are slidably mounted on the cabinet body. The top of the drawer has a mounting groove for mounting components. The bottom of the mounting groove is equipped with a wire storage assembly for winding and storing power supply wires. The wire storage assembly is slidably mounted on the bottom of the mounting groove. Multiple wire storage assemblies are provided.
[0006] In order to allow the reserved wires to be stored, the wire storage assembly includes a base plate and a winding post disposed on the base plate for winding the power wires.
[0007] To prevent the wires wound on the winding post from becoming loose or frizzy, the wire storage assembly also includes a rotating plate rotatably mounted on the winding post and wire clips fixedly mounted on the rotating plate for securing the power supply wires.
[0008] The power cable clip has a slot for inserting the power cable.
[0009] In order to enable the clamping and limiting of wires of different diameters, the wire clamping block includes a large wire clamping block for clamping thicker wires and a small wire clamping block for clamping thinner wires.
[0010] In order to dissipate heat in the mounting groove and limit the sliding of the substrate, a heat dissipation groove is provided at the bottom of the mounting groove. A connecting bolt that can slide in the heat dissipation groove is inserted in the heat dissipation groove. The threaded end of the connecting bolt passes through the substrate, and a hand-tightening nut is provided on the threaded end of the connecting bolt to clamp and limit the substrate.
[0011] In order to enable the wire storage assembly to be adjusted according to the position of the components, multiple heat dissipation slots are provided, and the substrate can be installed in any one of the heat dissipation slots.
[0012] To improve the heat dissipation of components in the mounting slot, multiple heat dissipation holes are provided on the wall of the mounting slot, and the multiple heat dissipation holes are arranged at intervals.
[0013] To further improve the convenience of winding and storing the reserved wires, a wire winding reel is provided on the side wall of the mounting slot. The wire winding reel can be inserted into and installed in any of the heat dissipation holes.
[0014] In summary, this application includes at least one of the following beneficial technical effects:
[0015] 1. The wires reserved on the components can be wound around the winding posts in the nearby wire storage components. Since there are multiple wire storage components, the reserved wires on multiple components can each correspond to a set of wire storage components, thus preventing the reserved wires of a certain length on multiple components from getting tangled together.
[0016] 2. After the wire is wound around the winding post, it can be inserted into the slot of the wire clip, so that the wire already wound on the winding post is not easy to loosen and become fluffy;
[0017] 3. The position of the wire storage component in the mounting slot can be slidable and adjusted, allowing the component to be moved next to the corresponding component according to the actual situation. At the same time, the rotating plate can rotate the wire clip, allowing the orientation of the clip to be adjusted according to the location of the component, thus improving the convenience of storing wires.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0024] This application discloses a low-voltage withdrawable switchgear. (Refer to...) Figure 1 and Figure 2 The low-voltage withdrawable switchgear includes a cabinet 1 and drawers 2. Drawers 2 are slidably mounted on the cabinet 1. The top of each drawer 2 has a mounting slot 21 for installing components. A wire storage assembly 3 for winding and storing power cables is slidably mounted on the bottom of the mounting slot 21. Multiple sets of wire storage assemblies 3 can be set according to the number of components in the mounting slot 21, so that each component's pre-installed wires can correspond to a separate set of wire storage assemblies 3. Multiple drawers 2 are arranged vertically on the cabinet 1. Each drawer 2 has the same structure, and each drawer 2 contains a certain number of wire storage assemblies 3. The following explanation uses one set of wire storage assemblies 3 inside one drawer 2 as an example.
[0025] Reference Figure 2 The mounting slot 21 has a heat dissipation groove 22 at its bottom, allowing heat generated by the components to dissipate from the mounting slot 21 through the heat dissipation groove 22. The extension direction of the heat dissipation groove 22 is consistent with the sliding direction of the drawer 2. Multiple heat dissipation grooves 22 are provided, spaced apart along the sliding direction of the drawer 2 and perpendicular to it. The cable storage assembly 3 slides along the extension direction of the heat dissipation groove 22, guided by it.
[0026] Reference Figure 2 and Figure 3 The wire storage assembly 3 includes a base plate 31, a winding post 32, a rotating plate 33, and a wire clamp 34. The base plate 31 can slide at the bottom of the mounting groove 21; the winding post 32 is fixed to the top of the base plate 31 to wind the power wire; the wire clamp 34 is fixed on the rotating plate 33, and the wire can be clamped on the wire clamp 34 and limited; the rotating plate 33 is rotatably mounted on the winding post 32 so that the orientation of the wire clamp 34 can be adjusted according to the position of the component.
[0027] Reference Figure 2 and Figure 3 Two bolt through holes are spaced apart on the top of the substrate 31. These two bolt through holes are perpendicular to the two heat dissipation slots 22 in the sliding direction of the drawer 2 and are connected to them. A connecting bolt 35 is inserted into the heat dissipation slot 22 on the side of the drawer 2 away from the mounting slot 21. The threaded end of the connecting bolt 35 passes through the heat dissipation slot 22 and is inserted into the bolt through hole, protruding from the bolt through hole. A hand-tightening nut 36 is threaded onto the part of the connecting bolt 35 that protrudes from the bolt through hole. By tightening the hand-tightening nut 36, the substrate 31 can be clamped and positioned on the drawer 2. This allows the substrate 31 to be fixed in place after its position is adjusted, preventing it from moving. Since there are two bolt through holes, there are also two connecting bolts 35 and two hand-tightening nuts 36. The two connecting bolts 35 are inserted into the two heat dissipation slots 22 and into the corresponding bolt through holes, while the two hand-tightening nuts 36 correspond one-to-one with the two connecting bolts 35. When it is necessary to adjust the position of the substrate 31, loosen the hand nut 36, and then move the substrate 31 so that it moves along the extension direction of the heat dissipation groove 22.
[0028] Alternatively, depending on the actual situation, the substrate 31 can be rotated 90 degrees so that the two connecting bolts 35 are inserted into the same heat dissipation slot 22, and then the substrate 31 can be adjusted and fixed. The specific adjustment can be made according to the usage.
[0029] Reference Figure 2 and Figure 3 A retaining ring 321 is integrally formed on the upper part of the winding column 32. A rotating plate 33 is sleeved on the winding column 32, and the rotating plate 33 is located above the retaining ring 321. Under the action of the retaining ring 321, the rotating plate 33 is limited and cannot move further towards the substrate 31. The wires wound on the winding column 32 are all located below the retaining ring 321. An external thread is provided on the outer wall of the winding column 32 on the side away from the substrate 31. The external thread is located above the rotating plate 33. A retaining nut 322 is sleeved and threaded onto the external thread. The rotating plate 33 is located between the retaining nut 322 and the retaining ring 321. Under the action of the retaining nut 322, the rotating plate 33 is not easily detached from the winding column 32.
[0030] Reference Figure 2 and Figure 3The wire clamping block 34 includes a large wire clamping block 37 and a small wire clamping block 38, which are arranged at intervals on the rotating plate 33 along the extension direction of the rotating plate 33, and multiple small wire clamping blocks 38 are provided. Both the large wire clamping block 37 and the small wire clamping block 38 have a slot 39 for inserting the power supply wire. However, the slot 39 on the large wire clamping block 37 is larger, so that a thicker diameter wire can be inserted; the slot 39 on the small wire clamping block 38 is smaller, so that a thinner diameter wire can be inserted.
[0031] Reference Figure 2 and Figure 4 The mounting slot 21 has multiple heat dissipation holes 23 on its wall to allow heat generated by the components to dissipate. These holes are spaced apart on the wall of the mounting slot 21. A take-up reel 4 for winding power cables is installed on one side of the mounting slot 21. Excess wires from the components can also be wound onto the take-up reel 4. An integrally formed threaded post 41 on one side of the outer wall of the take-up reel 4 is inserted into any one of the heat dissipation holes 23. The end of the threaded post 41 facing away from the take-up reel 4 passes through the heat dissipation hole 23 and is fixed to the drawer 2 by a nut. Because the threaded post 41 can be inserted into any one of the heat dissipation holes 23, the position of the take-up reel 4 can be adjusted according to the actual situation.
[0032] The implementation principle of a low-voltage withdrawable switchgear according to this application embodiment is as follows: Each wire storage assembly 3 can be installed on one side of a corresponding component. The wires pre-existing on the component can be wound around the winding post 32. Then, the wires are clipped into the wire clip 34 to prevent the wires already wound on the winding post 32 from becoming loose and forming a fluffy state, thus preventing multiple wires from getting tangled together. The position of the wire storage assembly 3 in the mounting groove 21 can be slidably adjusted, thereby allowing the position of the wire storage assembly 3 to be adjusted according to the actual situation, moving the wire storage assembly 3 next to the corresponding component. At the same time, the rotating plate 33 can drive the wire clip 34 to rotate, so that the orientation of the wire clip 34 can be adjusted according to the location of the component, thereby improving the convenience of storing wires.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
