[0002] High-voltage incoming line cabinets, as key equipment in power systems, play a crucial role in the reception and distribution of electrical energy. They are mainly deployed at the power input terminals of substations and distribution rooms. This equipment has multiple functions: first, it controls the on / off switching of high-voltage circuits; second, it provides short-circuit and overload protection for downstream equipment; and third, it monitors key parameters such as current and voltage in real time. Its core components include high-voltage circuit breakers, disconnecting switches, current / voltage transformers, protective relays, and measuring instruments. Among them, the circuit breaker undertakes the opening and closing operations under normal operating conditions and rapid disconnection under fault conditions; the disconnecting switch provides electrical isolation for maintenance work; and the transformers realize the safe conversion of high voltage and high current, providing standardized signals for system monitoring and protection.

[0003] In terms of internal structure, high-voltage incoming line cabinets usually need to lay multiple high-voltage cables. Traditional cable fixing devices mostly use rigid structures such as direct bolt tightening or metal cable ties, which have obvious limitations. First, they have poor adaptability and are difficult to be compatible with cables of different diameters and specifications. Second, when the cable size does not match the clamp, it is easy to cause the insulation layer to be damaged by excessive crimping or to be loose due to insecure fixing. Therefore, improvements are needed. Utility Model Content

Detailed Implementation

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0022] Please see Figures 1 to 4 The adjustable high-voltage incoming line cabinet cable clamp includes an incoming line cabinet body 1, on which an inlet port 16 is provided, and a dustproof brush 17 is fixedly connected inside the inlet port 16. A cable clamp body 2 is detachably installed inside the incoming line cabinet body 1, and the cable clamp body 2 has several plug slots 7. A cable fixing assembly is detachably installed on the cable clamp body 2.

[0023] Specifically, the inlet 16 is the channel for cable introduction. The dustproof bristles 17 fixedly installed inside it can effectively block external dust, insects and other pollutants from entering the cabinet while allowing the cable to pass freely, thereby maintaining a clean environment inside the electrical equipment and reducing the risk of short circuits or insulation performance degradation caused by dust accumulation.

[0024] The cable fixing assembly includes an adjustable length fixing strap 8, with plug blocks 9 fixedly connected to both ends of the fixing strap 8, each plug block 9 being inserted into the plug slot 7. An adjustment seat 11 is mounted on the fixing strap 8, and an operation port 12 is provided on the fixing strap 8. Each plug block 9 has two fastening slots 10.

[0025] The fixing strap 8 can be directly inserted into the cable clamp body 2. With the cooperation of the adjusting seat 11, the length of the fixing strap 8 can be adjusted arbitrarily to ensure that the cable is securely fixed. The buckle groove 10 can facilitate the disassembly of the plug-in block 9.

[0026] A placement base 13 is detachably mounted on the cable clamp body 2. A mounting block 14, compatible with the insertion slot 7, is fixedly connected to the bottom of the placement base 13. The placement base 13 is inserted into the cable clamp body 2 via the mounting block 14. The upper surface of the placement base 13 is curved, and a protective pad 15 is fixedly connected to the upper surface of the placement base 13. The curved surface of the placement base 13 makes the cable placement more stable, and the protective pad 15, made of silicone, provides a cushioning effect, preventing direct friction between the cable sheath and the metal base.

[0027] A fixing block 5 is fixedly connected to the cable clamp body 2. The fixing block 5 has a threaded hole, and a locking bolt 6 is threaded into the threaded hole. One end of the locking bolt 6 is in contact with the inside of the incoming line cabinet body 1. Two sliding strips 3 are fixedly connected inside the incoming line cabinet body 1. The cable clamp body 2 has a sliding groove 4 that matches the sliding strips 3. The cable clamp body 2 is slidably connected to the sliding strips 3 through the sliding groove 4. One end of the locking bolt 6 is in contact with the sliding strip 3.

[0028] By using the locking bolt 6 to pass through the threaded hole of the fixing block 5 and tighten the slide bar 3, the cable clamp body 2 can be fixed, making it securely installed and used.

[0029] Working principle: In use, the cable clamp body 2 can be installed inside the main body 1 of the cable inlet cabinet through the cooperation of the sliding groove 4 and the sliding strip 3. By screwing the locking bolt 6 into the threaded hole of the fixing block 5, the cable clamp body 2 can be fixed to prevent it from loosening or shifting. When fixing the cable, the cable can be placed on the placement seat 13. Its arc surface and protective pad 15 can reduce the friction and compression of the cable and avoid damage. The plug-in blocks 9 set at both ends of the fixing band 8 can be directly inserted into the plug-in slots 7 on the cable clamp body 2. The shape can be used to lock it directly. Then, the length of the fixing band 8 can be adjusted by adjusting the seat 11 and the operating port 12 to adapt to the cable size. Multiple fixing bands 8 can be installed at the same time by using the multiple plug-in slots 7 to achieve parallel fixing of multiple cables and improve space utilization. The dustproof bristles 17 at the cable inlet 16 can block dust from entering, keep the inside clean, and reduce maintenance needs.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
