[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Please see Figures 1 to 4 This utility model provides an embodiment of an intelligent power grid relay protection cabinet that facilitates cable routing and management. The cabinet includes a main body 1, with a cabinet door 2 rotatably connected to the front end. Cable routing units 3 are installed on both sides of the main body 1, symmetrically arranged relative to the main body 1. Each cable routing unit 3 includes a cable winding box 304. The main body 1 is fixedly connected to the two cable winding boxes 304. Two cable routing sleeves 303 are fixedly installed at the bottom of the cable winding boxes 304. Cable routing grooves 305 are provided on the inner side of each cable routing sleeve 303. A sealing box 302 is installed at the bottom of the cable winding box 304. The bottom of the cable winding box 304 is fixedly connected to the sealing box 302 through a cable tray 303. A fork bracket 301 is fixedly installed on one side of the two sealing boxes 302. The cable winding box 304 is connected to the sealing box 302 and the fork bracket 301 through a cable tray 305. A winding column is provided inside the cable winding box 304, so that after the cable is wound and installed inside the cable winding box 304 through the winding column, it passes through the cable tray 305 and the sealing box 302 in sequence and is centrally output through the fork bracket 301.
[0021] Cables are installed on the inner side of the branch bracket 301. The upper end of the cable passes through the sealing box 302 and the cable tray 305 in sequence and is wound around the outside of the winding column. The interior of the sealing box 302 is filled with flame-retardant foam. By filling the sealing box 302 with flame-retardant foam, the flame-retardant foam can maintain the stability of the cable arrangement. At the same time, the flame-retardant foam can seal the sealing box 302 to prevent external dust and rainwater from flowing back into the interior of the electrical cabinet body 1 through the branch bracket 301 and the sealing box 302.
[0022] Please see Figures 2 to 4 Multiple cable guide units 4 are installed on one side of each of the two cable-laying units 3 facing each other. The multiple cable guide units 4 are arranged linearly along the axis of the cable-laying sleeve 303. The cable guide unit 4 includes a ball-head sleeve 401. The ball-head sleeve 401 is connected to the cable-laying sleeve 303 by a thread. A tapered sleeve 402 is movably installed on the inner side of the ball-head sleeve 401. A locking knob 404 is installed on the upper end of the ball-head sleeve 401. The bottom end of the locking knob 404 passes through the ball-head sleeve 401 and is in contact with the surface of the tapered sleeve 402. The locking knob 404 is connected to the ball-head sleeve 401 by a thread. The ball-head sleeve 401 and the tapered sleeve 402 are locked together by the locking knob 404. The locking knob 404 can keep the tapered sleeve 402 at different installation angles relative to the ball-head sleeve 401, so as to facilitate the input of cables in different directions to the inner side of the cable-laying sleeve 303.
[0023] One end of the tapered sleeve 402 is provided with a guide port 403. The inner side of the tapered sleeve 402 near the ball head sleeve 401 is provided with a cable guide channel 405. The guide port 403 and the cable tray 305 are connected through the cable guide channel 405. Multiple cable guide units 4 are used to realize the multi-point input and arrangement of cables, reducing the messiness of cables in the main body of the electrical cabinet 1.
[0024] In summary, when routing and arranging cables within the relay protection cabinet, two cable routing units 3 are symmetrically installed inside the main body 1 of the cabinet. This ensures that the branch bracket 301, cable winding box 304, two cable routing sleeves 303, and sealing box 302 in the cable routing unit 3 are all fixedly connected to the main body 1 of the cabinet. Meanwhile, the cable winding box 304 is connected to the sealing box 302 and the branch bracket 301 through the cable routing groove 305. A winding post is provided inside the cable winding box 304, allowing the cable to be wound and installed inside the cable winding box 304 through the winding post, then sequentially passing through the cable routing groove 305 and the sealing box 302, and being centrally output through the branch bracket 301.
[0025] The cable trays 305 within the two cable trays 303 can be used to distribute the cables, thereby reducing the density between the cables. By filling the sealed box 302 with flame-retardant foam, the flame-retardant foam can fix the cables within the sealed box 302, maintaining the stability of the cable arrangement. At the same time, the flame-retardant foam can seal the sealed box 302, preventing external dust and rainwater from flowing back into the inside of the main body of the electrical cabinet 1 through the branch bracket 301 and the sealed box 302.
[0026] Multiple cable guide units 4 are arranged linearly on one side of the cable tray 303, and the guide port 403 inside the conical sleeve 402 is connected to the cable tray 305 through the cable guide channel 405. This allows the conical sleeve 402 to guide the cables in the main body of the electrical cabinet 1 to the inside of the cable tray 305 through the guide port 403 and the cable guide channel 405 in sequence. At the same time, the ball head sleeve 401 and the conical sleeve 402 are locked together by the locking knob 404. The locking knob 404 can keep the conical sleeve 402 at different installation angles relative to the ball head sleeve 401, which can facilitate the input of cables from different directions to the inside of the cable tray 303. The multiple cable guide units 4 enable multi-point input and arrangement of cables, reducing the messiness of cables in the main body of the electrical cabinet 1.
