Description

Technical Field

[0001] This utility model relates to the technical field of high and low voltage distribution cabinet structure, and in particular to an integrated high and low voltage distribution cabinet with leakage current monitoring function. Background Technology

[0002] High and low voltage switchgear are power distribution equipment used in power supply systems for power distribution, control, metering, and cable connection. Generally, power supply bureaus and substations use high voltage switchgear, which is then stepped down by transformers to the low voltage side and led out to low voltage switchgear. The low voltage switchgear then leads to various power distribution panels, control boxes, and switch boxes. Inside, there are power distribution devices that integrate switches, circuit breakers, fuses, buttons, indicator lights, meters, wires, and other protective devices to achieve the designed functional requirements.

[0003] A search revealed that authorization announcement number CN218124053U discloses a distribution cabinet with leakage current detection function, including a cabinet. The inner walls of both sides of the cabinet are fixed to corresponding sides of a placement platform. The top of the placement platform has fixing grooves at both ends on one side, and magnetic plates are installed on the bottom inner walls of each fixing groove. Mounting plates are installed on the top of the placement platform on the side corresponding to the fixing groove, and the interior of each mounting plate is movably connected to a corresponding end of a rotating rod. A placement plate is installed on the outer side of the rotating rod near the middle, and handles are installed on the outer side of the rotating rod near both ends. The outer surface of each handle is covered with anti-slip pads. The design of the mounting plate, rotating rod, placement plate, handles, and anti-slip pads effectively solves the problem of inconvenience caused by the leakage current detector being installed parallel inside the cabinet during operation.

[0004] However, existing high and low voltage distribution cabinets may experience leakage during use, which poses a significant safety hazard. Therefore, there is an urgent need in the market for an integrated high and low voltage distribution cabinet with leakage current monitoring function to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated high and low voltage distribution cabinet with leakage current monitoring function, so as to solve the problem mentioned in the background art that existing high and low voltage distribution cabinets may have leakage current during use, which will bring significant safety hazards.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An integrated high and low voltage distribution cabinet with leakage current monitoring function includes a high and low voltage distribution cabinet body, a sealed door installed at the front end of the cabinet body, a display screen installed at the front end of the sealed door, control buttons installed at the lower end of the display screen, a monitoring room door installed on one side of the sealed door, a monitoring room inside the monitoring room door, a support frame one installed inside the monitoring room, a support frame two installed below the support frame one, an industrial 4G module installed above the support frame one, a control module installed above the support frame two, a leakage current monitoring device installed below the support frame two, a leakage current protection switch installed below the leakage current monitoring device, and an alarm light installed on the top of the high and low voltage distribution cabinet body.

[0008] By adopting the above technical solution, integrated high and low voltage distribution cabinets can be equipped with leakage current monitoring function. When leakage current occurs in the integrated high and low voltage distribution cabinet, it can be detected in time and dealt with quickly.

[0009] Furthermore, the lower end of the high and low voltage distribution cabinet is provided with support feet. The support feet are an integral structure with the high and low voltage distribution cabinet. There are four support feet, which are symmetrical about the vertical center line of the lower end of the high and low voltage distribution cabinet.

[0010] By adopting the above technical solution, the structure between the support feet and the high and low voltage distribution cabinet can be made more robust, thus allowing the high and low voltage distribution cabinet to be easily supported by the support feet.

[0011] Furthermore, heat dissipation and protection nets are installed inside the two opposite outer walls of the high and low voltage distribution cabinet.

[0012] By adopting the above technical solution, the heat dissipation protection net will not affect the heat dissipation effect of the high and low voltage distribution cabinet, and at the same time, it can prevent external debris from entering the interior of the high and low voltage distribution cabinet.

[0013] Furthermore, both the monitoring room door and the sealed door are equipped with handles at their front ends.

[0014] By adopting the above technical solution, the monitoring room door and the sealed door can be easily opened using the handle.

[0015] Furthermore, the first support frame is welded to the monitoring room, and the second support frame is welded to the monitoring room.

[0016] By adopting the above technical solutions, the structure between support frame one and the monitoring room can be made more robust, and the structure between support frame two and the monitoring room can be made more robust.

[0017] Furthermore, the lower end of the control module is provided with a fixing foot, which is fixedly connected to the second support frame by fixing screws. The leakage current monitoring device is provided with mounting feet around its perimeter, which are fixedly connected to the monitoring chamber by mounting screws.

[0018] By adopting the above technical solution, the control module and leakage current monitoring equipment can be easily installed and fixed.

[0019] Furthermore, the control module is electrically connected to the industrial 4G module, the control module is electrically connected to the leakage current monitoring device, the control module is electrically connected to the alarm light, and the leakage current monitoring device is electrically connected to the leakage current protection switch.

[0020] By adopting the above technical solution, the components can be matched together, thereby enabling leakage current monitoring of high and low voltage distribution cabinets.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) This utility model can monitor the inside of the high and low voltage distribution cabinet in real time by installing leakage monitoring equipment. When leakage occurs inside the high and low voltage distribution cabinet, after the leakage monitoring equipment detects it, the leakage signal is transmitted to the terminal through the industrial 4G module via the control module. Then the terminal staff can discover and deal with it in time. At the same time, the alarm light is controlled by the control module to alarm, so as to remind the surrounding people to pay attention to the danger of leakage.

[0023] (2) Both ends of the outer wall of the high and low voltage distribution cabinet of this utility model are provided with heat dissipation protection nets. The heat dissipation protection nets installed can prevent external debris from entering the interior of the high and low voltage distribution cabinet without affecting the heat dissipation of the high and low voltage distribution cabinet, thereby damaging the components installed inside the high and low voltage distribution cabinet.
