[0001] This utility model relates to the field of low-voltage distribution cabinet technology, specifically a low-voltage distribution cabinet with line status monitoring and early warning. Background Technology

[0002] Low-voltage switchgear is an electrical device used in power systems with AC voltage of 1000V and below for power distribution, control and protection. Low-voltage switchgear plays a vital role in modern power systems. It is not only the central hub for power distribution and control, but also an important line of defense for ensuring the safe and stable supply of power.

[0003] During use, the above-mentioned equipment has its wiring directly connected to the distribution cabinet via connectors. In existing technologies, the switch status is mostly monitored using components such as reflective photoelectric switches and sensors. However, in practical applications, the wiring connection is also crucial. If the wiring becomes loose or disconnected, the normal operation of the distribution cabinet will be affected. This could range from affecting the continuity of the circuit system to causing short circuits or even fires, posing certain safety hazards. Therefore, optimization and improvement are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a low-voltage distribution cabinet with line status monitoring and early warning, so as to solve the problem mentioned in the background art that it is difficult for low-voltage distribution cabinets to monitor the line connection status, which affects the efficiency of low-voltage distribution cabinet use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage distribution cabinet with line status monitoring and early warning, comprising: a cabinet body, a maintenance door panel connected to the top front end of the cabinet body, a control panel installed at the bottom front end of the cabinet body, an electrical equipment body installed on the inner front end of the cabinet body, and further comprising a line monitoring component and a line positioning component:

[0006] The line monitoring component includes a mounting bracket installed at the center of the bottom inner side of the cabinet, with a telescopic adjustment mounting plate at the top and a snap-fit ​​frame at the top. The line monitoring component is used to monitor the wire connection strength. The line positioning component includes a lower snap-fit ​​frame located at the rear of the bottom inner side of the cabinet, with an upper snap-fit ​​frame at the top and a socketed positioning ring on the inner side. The line positioning component is used for guiding and positioning the line.

[0007] Preferably, a pressure sensor is fixedly mounted on one side of the mounting bracket.

[0008] Preferably, a support column is installed at the top of the mounting frame, and an elastic connector is connected to the top of the support column. The telescopic adjustment mounting plate is located at the top outer side of the support column.

[0009] Preferably, a positioning screw hole is provided on one side of the top of the snap-fit ​​frame, and a limiting rotating plate is connected to the other side of the top of the snap-fit ​​frame, with a positioning screw connected to the inner side of the limiting rotating plate.

[0010] Preferably, both sides of the lower bracket are connected to a fixing plate, and the top of the fixing plate is connected to a rotating screw.

[0011] Preferably, both sides of the sleeve positioning ring are connected to adjustment plates, and the adjustment plates are threadedly connected to the rotating screw.

[0012] Preferably, the support column and the telescopic adjustment mounting plate are slidably connected, and the elastic connector and the telescopic adjustment mounting plate are elastically connected.

[0013] Preferably, the inside of the snap-fit ​​frame is provided with an arc-shaped slot, which is used for bending and positioning of the wire.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model uses a snap-fit ​​frame at the bottom of the electrical equipment's main body to snap and limit the wire connection. The bottom is then supported by a telescopic adjustable mounting plate connected to a support column. When the wire breaks or falls off, the telescopic adjustable mounting plate rises, and the pressure change is monitored by a pressure sensor.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1 - Figure 5 As shown, this application provides a low-voltage distribution cabinet with line status monitoring and early warning, including: cabinet 1, maintenance door 2 connected to the top front end of cabinet 1, control panel 3 installed at the bottom front end of cabinet 1, and electrical equipment body 4 installed on the front inner side of cabinet 1.

[0026] The line monitoring component includes a mounting bracket 5, which is installed in the middle of the bottom inner side of the cabinet 1. The top of the mounting bracket 5 is provided with a telescopic adjustment mounting plate 9, and the top of the telescopic adjustment mounting plate 9 is provided with a snap-fit ​​frame 10. The line monitoring component is used to monitor the strength of the wire connection.

[0027] Specifically, such as Figure 2 As shown, a pressure sensor 6 is fixedly installed on one side of the mounting bracket 5. The pressure sensor 6 detects the pressure that the telescopic adjustment mounting plate 9 bears when it is pressed down. When the wire falls off, the telescopic adjustment mounting plate 9 will rebound and rise under the elastic force of the elastic connector 8. At this time, the pressure sensor 6 will monitor the data.

[0028] Specifically, such as Figure 3As shown, a support column 7 is installed at the top of the mounting bracket 5, and an elastic connector 8 is connected to the top of the support column 7. The telescopic adjustment mounting plate 9 is located at the top outer side of the support column 7. The support column 7 and the telescopic adjustment mounting plate 9 are slidably connected, and the elastic connector 8 and the telescopic adjustment mounting plate 9 are elastically connected. The telescopic adjustment mounting plate 9 slides downward on the outside of the support column 7 during installation due to the elastic force of the elastic connector 8.

[0029] Specifically, such as Figure 3 As shown, a positioning screw hole 11 is provided on one side of the top of the snap-fit ​​frame 10, and a limiting rotating plate 12 is connected to the other side of the top of the snap-fit ​​frame 10. A positioning screw 13 is connected to the inner side of the limiting rotating plate 12. When the wire is snapped into the arc-shaped slot inside the snap-fit ​​frame 10, the limiting rotating plate 12 rotates half a turn to limit it to the top of the snap-fit ​​frame 10, and is fixed by connecting the positioning screw hole 11 to the positioning screw 13, further limiting the stability of the wire fixation.

[0030] The line positioning component includes a lower card holder 14, which is located at the rear of the inner bottom of the cabinet 1. An upper card holder 18 is provided at the top of the lower card holder 14, and a sleeve positioning ring 17 is provided on the inner side of the upper card holder 18. The line positioning component is used for guiding and positioning the line.

[0031] Specifically, such as Figure 4 As shown, both sides of the lower clip bracket 14 are connected to a fixing plate 15, and the top of the fixing plate 15 is connected to a rotating screw 16. The fixing plate 15 and the rotating screw 16 are rotatably connected, which allows for adjustment of the clamping of the wire during use.

[0032] Specifically, such as Figure 4 As shown, both sides of the positioning ring 17 are connected to adjustment plates 19, and the adjustment plates 19 are threadedly connected to the rotating screws 16. The adjustment plates 19 move up and down during the rotation adjustment of the rotating screws 16 on both sides, which facilitates the clamping of the wires inserted on the inside.

[0033] Specifically, such as Figure 3 As shown, the inside of the snap-fit ​​frame 10 is provided with an arc-shaped slot, which is used for bending and positioning of the wire. The edge of the arc-shaped slot inside the snap-fit ​​frame 10 is smooth, which reduces wear when in contact with the wire.

[0034] In this embodiment: a clamping frame 10 is set at the bottom end of the electrical equipment body 4 to clamp and limit the wire. Then, the bottom end is supported by the retractable connection between the telescopic adjustment mounting plate 9 and the support column 7. When the wire breaks or falls off, the telescopic adjustment mounting plate 9 rises, and the change in pressure value is monitored by the pressure sensor 6. The wire is clamped by the lower clamping frame 14 and the upper clamping frame 18. The wire is protected by the sleeve positioning ring 17 at the contact position between the wire and the clamping frame.

[0035] Specifically, this solution involves fixing the wires using the lower clamping bracket 14 and upper clamping bracket 18 during installation. The outer rotating screw 16 rotates, bringing the adjusting plate 19 closer to the fixing plate 15 for clamping. Then, a positioning ring 17 is used for protection at the point where the wires are in close contact with the lower clamping bracket 14 and upper clamping bracket 18. The tightness of the installation is adjusted by turning the rotating screw 16, ensuring stable clamping for wires of different thicknesses within a certain range, reducing the risk of wire detachment. This facilitates the removal of wires from the clamping bracket. When the wires fall off, timely maintenance can be carried out. A snap-fit ​​frame 10 is set at the bottom of the electrical equipment body 4 to snap and limit the wires. The arc-shaped slot inside the snap-fit ​​frame 10 is adapted to snap the wires. The bottom is supported by the retractable connection between the telescopic adjustment mounting plate 9 and the support column 7. When the wires break or fall off, the telescopic adjustment mounting plate 9 rises under the elastic force of the elastic connector 8. The change in pressure value is monitored by the pressure sensor 6 to monitor the stability of the wire connection, improve maintenance efficiency, and reduce the risk of use.

[0036] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

[0037] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
