Description

Technical Field

[0001] This utility model relates to the field of high and low voltage switchgear technology, specifically a high and low voltage switchgear that facilitates wiring. Background Technology

[0002] High-voltage and low-voltage switchgear are key equipment in power distribution systems used for controlling and protecting circuits. They are classified into high-voltage and low-voltage switchgear according to voltage level. They are widely used in power plants, substations, industrial and mining enterprises, and various building power distribution systems to ensure the safe and reliable operation of the power system. The main functions of high-voltage switchgear include: control (connecting or disconnecting high-voltage circuits); protection (cutting off circuits in case of short circuits, overloads, etc., to prevent equipment damage); and isolation (isolating high-voltage equipment from the power supply to ensure safe maintenance). The main functions of low-voltage switchgear include: energy distribution (distributing electrical energy to different loads); motor control (starting, stopping, and protecting motors); and circuit protection (overload, short circuit, leakage current protection, etc.). High-voltage and low-voltage switchgear are indispensable equipment in power systems.

[0003] Traditional high and low voltage switchgear relies solely on cabling ports to allow cables to enter the cabinet and connect to corresponding electrical components. When multiple cables enter, high-voltage and low-voltage cables become tangled, leading to unstable signal transmission. To address this issue, some high and low voltage switchgear designs incorporate cable management racks with multiple vertical channels. Each channel corresponds to a specific type or function of cable, and separators between adjacent channels prevent cross-contamination, ensuring signal transmission stability. However, this method, with multiple cables of the same type intertwined in the same vertical channel, not only creates safety hazards but also increases maintenance difficulty. Therefore, a high and low voltage switchgear design facilitating cable management is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a high and low voltage switch cabinet that facilitates wiring, so as to solve the above-mentioned technical problems that not only cause safety hazards, but also increase the difficulty of maintenance.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high- and low-voltage switchgear that facilitates wiring, comprising:

[0008] The cabinet body, and the cabinet door set on the front of the cabinet body, and the support base is installed on the lower surface of the cabinet body, and four side through grooves are opened on the outer side of the support base. The upper part of the inner cavity of the cabinet body is installed with a fixing frame, and the cable routing ports are evenly opened at the bottom of the cabinet body and the support base.

[0009] The comb frame is slidably connected to the lower part of the inner cavity of the cabinet. Vertical channels are opened downward on the left and right sides and the center of the upper surface of the comb frame. Partition plates are installed on both sides of the center of the inner cavity of the comb frame. Limit grooves are opened on the left and right inner walls of the comb frame and the left and right sides of the partition plates. Isolation plates are slidably connected to the inner cavity of the vertical channels. Limit rails are installed on both sides of the isolation plates.

[0010] A positioning post is inserted into the front end of the limiting groove, and a limiting rail is slidably connected to the limiting groove. A positioning rail is also installed on the back of the positioning post. Electrical equipment is mounted on a fixed frame, and cables sequentially enter the cabinet through side channels and cable routing openings. The cables ascend along the cable comb frame via corresponding vertical channels to connect with the electrical equipment. A partition plate is slidably installed within the corresponding vertical channel. The partition plate slides along the limiting groove via the limiting rail, separating cables within the same vertical channel. After the positioning post and positioning rail move downwards along the front end of the limiting groove, the positioning post is inserted into the front end of the limiting groove. The cabinet door is then closed. This process effectively separates cables within the same vertical channel, preventing safety hazards and reducing maintenance difficulty. Furthermore, the sliding positioning post and positioning rail ensure the stability of the connection between the partition plate and the cable comb frame.

[0011] Preferably, the mounting bracket is square in shape, and mounting holes are evenly distributed on its front side. The mounting bracket is connected to electrical equipment through these mounting holes.

[0012] Preferably, the inner walls of the cabinet are provided with side connecting grooves on both the left and right sides, and the comb frame is equipped with side connecting plates on both the left and right sides. When the comb frame is connected to the cabinet, the side connecting plates are inserted into the side connecting grooves.

[0013] Preferably, both the side connecting plate and the side connecting groove are square in shape, and the side connecting plate and the side connecting groove are slidably connected. The side connecting plate can slide along the inner cavity of the side connecting groove.

[0014] Preferably, the upper surfaces of the comb frame and the partition plate are respectively provided with positioning holes and positioning grooves, and the positioning holes and positioning grooves are connected. The positioning posts and positioning rails are respectively inserted and connected to the positioning holes and positioning grooves. The comb frame and the partition plate can be raised and lowered along the positioning holes and positioning grooves, thereby ensuring the stability of the connection between the limiting rail and the limiting groove.

[0015] Preferably, the bottom of the inner cavity of the cabinet is provided with threaded holes evenly distributed, and each threaded hole is threadedly connected to a winding rod. The winding rod is threaded into the threaded hole, and when the cable passing through the cable tray is too long, the cable can be wound around the winding rod, thereby avoiding the cable length affecting the cable routing operation.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a high and low voltage switchgear that facilitates wiring, and has the following beneficial effects:

[0018] This high and low voltage switchgear, which facilitates cable routing, allows electrical equipment to be mounted on a fixed frame. Cables enter the cabinet sequentially through side channels and cable routing ports. The cables then ascend along the cable comb frame via corresponding vertical channels to connect with the electrical equipment. Isolation plates are slidably installed within these vertical channels. These isolation plates slide along limit grooves via limit rails, separating cables within the same vertical channel. After the positioning posts and positioning rails move downwards along the front end of the limit groove, the positioning posts are inserted into the front end of the limit groove. Closing the cabinet door and cabinet body further separates the cables within the same vertical channel, preventing safety hazards and reducing maintenance difficulty. The sliding positioning posts and positioning rails also ensure the stability of the connection between the isolation plates and the cable comb frame. Attached Figure Description

[0029] The positioning post 18 is inserted at the front end of the limiting groove 13, and the limiting rail 15 is slidably connected to the limiting groove 13. The positioning rail 19 is installed on the back of the positioning post 18. By installing electrical equipment on the mounting frame 5, cables sequentially enter the cabinet 1 through the side channel 4 and the cable routing port 7. The cables rise along the comb frame 9 through the corresponding vertical channel 11 and connect to the electrical equipment. An isolation plate 14 is slidably installed in the corresponding vertical channel 11. The isolation plate 14 slides along the limiting groove 13 via the limiting rail 15.
