Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a power distribution switch cabinet. Background Technology

[0002] The main function of switchgear is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes in a power system. The main components of switchgear include circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers, and various protective devices. Switchgear can be classified in many ways, such as by the circuit breaker installation method (removable switchgear and fixed switchgear); or by the cabinet structure (open switchgear, metal-enclosed switchgear, and metal-enclosed armored switchgear); and by voltage level (high-voltage switchgear, medium-voltage switchgear, and low-voltage switchgear). It is mainly suitable for various applications such as power plants, substations, petrochemical plants, metallurgical steel rolling mills, light industry and textiles, factories and mines, residential communities, and high-rise buildings.

[0003] Switch cabinets contain numerous electrical appliances, which can easily overheat after prolonged operation. Cooling devices are typically used to cool them down and ensure normal operation. However, existing switch cabinets usually have these cooling devices fixed inside. When operators need to inspect or clean them, they must first disconnect the power before accessing the cooling devices inside the cabinet. This process causes equipment downtime, impacting efficiency. Furthermore, the cabinet's interior is cluttered with wiring and limited space, making operation inconvenient.

[0004] Therefore, we propose a power distribution switch cabinet to solve the above problems. Utility Model Content

[0018] This invention utilizes connecting blocks on both sides of the heat dissipation mechanism's installation location. The heat dissipation mechanism's connecting seats on both sides are rotatably connected to the protruding posts on the connecting blocks, allowing the heat dissipation mechanism to rotate within its recessed area. A movable drawer allows the mechanism to move along its internal track. During maintenance, only the power supply to the multiple cooling fans connected to the movable drawer needs to be disconnected; there's no need to completely disconnect the internal circuitry, effectively preventing losses due to equipment downtime. A filter installed on the other side of the movable drawer further filters airborne dust. After power is disconnected, the movable drawer can be pulled out, and the filter can be removed to clean the filter holes on both the heat dissipation mechanism and the filter, ensuring the equipment continues to function normally.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figure 1-5As shown in the figure, an embodiment of the present invention provides a power distribution switch cabinet, comprising: a cabinet body 1, a cabinet door 2 installed on one side of the cabinet body 1, two sets of heat dissipation mechanisms 3 respectively installed on the cabinet door 2 and on one side of the cabinet body 1, and a movable drawer 4 installed inside the heat dissipation mechanism 3; further comprising: two sets of identical grooves are provided on the top of the back of the cabinet body 1 and slightly below the middle part of the cabinet door 2, the groove on the cabinet door 2 serves as an air inlet, and the groove on the cabinet body 1 serves as an air outlet, the size of the two sets of grooves is matched with the heat dissipation mechanism 3, two sets of connecting blocks 8 are fixed on both sides of the grooves on the cabinet body 1 and the cabinet door 2, a set of protruding posts are fixed on the side of the connecting block 8 near the groove, two sets of connecting seats are fixed on both sides of the heat dissipation mechanism 3, and the heat dissipation mechanism 3 is installed in the groove by means of the round holes on the connecting seats that match the protruding posts on the connecting blocks 8, allowing the heat dissipation mechanism 3 to be installed and rotated inside it. A strip-shaped louver is provided on one side of the heat dissipation mechanism 3, which can block dust and debris to a certain extent while providing ventilation. Two sets of identical track grooves are provided on both sides of the interior of the heat dissipation mechanism 3. The dimensions of the two sides of the movable drawer 4 match the dimensions of the two sides inside the heat dissipation mechanism 3, allowing the movable drawer 4 to move along the track provided on the heat dissipation mechanism 3. A set of slots is provided on one side of the movable drawer 4, and a set of threaded holes is provided on the heat dissipation mechanism 3 at the same position as the movable drawer 4. A set of limit bolts can be connected to the threaded holes on the heat dissipation mechanism 3 to limit the position of the movable drawer 4. Multiple sets of threaded holes are provided on the side of the movable drawer 4 away from the heat dissipation mechanism 3. The cooling fan 6 is installed on the movable drawer 4 by means of positioning bolts corresponding to the threaded holes on the movable drawer 4 through the fixing seats provided on both sides. Two sets of filter screens 5 are also installed on the side of the movable drawer 4 close to the heat dissipation mechanism 3. The filter screens 5 have multiple sets of filter holes. The filter screens 5 can further filter dust and debris in the air by filtering through the side of the heat dissipation mechanism 3, so as to prevent them from entering the cabinet and affecting the electrical equipment. A set of limiting blocks is fixed at the top of the groove on the cabinet door 2, which can restrict the rotation direction of the heat dissipation mechanism 3, allowing it to rotate only into the cabinet body 1. There is a set of threaded holes at the bottom of the groove inside the cabinet door 2. The knob 7 is installed on the cabinet door 2 by threaded connection through the threaded post installed at the bottom. Simply turning the knob 7 can simultaneously limit the heat dissipation mechanism 3 using the limiting blocks at the top of the groove. The cabinet body 1 has the same threaded holes on the side away from the cabinet door 2. The same set of knobs 7 can also limit the heat dissipation mechanism 3 installed on the cabinet body 1.

[0028] The cabinet body 1 and the cabinet door 2 are connected by hinges, allowing the cabinet door 2 to rotate on the cabinet body 1. For maintenance and cleaning, simply open the cabinet door 2 to inspect or clean the heat dissipation mechanism 3 installed on it. First, disconnect the circuit that drives the cooling fan 6; this process will not affect other electrical equipment inside the cabinet. Then, turn the knob 7 installed below the groove on the cabinet door 2 to remove the limiting position of the heat dissipation mechanism 3. Utilize the connection between the connecting block 8 and the heat dissipation mechanism 3 to rotate it. Once the heat dissipation mechanism 3 is rotated to a position where the movable drawer 4 can be removed, remove the limiting bolts installed on the heat dissipation mechanism 3, allowing the movable drawer 4 to be pulled out. After removing the movable drawer 4, the filter 5 on one side or the cooling fan 6 on the other side can be cleaned or replaced. The same applies to the other cooling mechanism 3 installed on the cabinet 1. Cleaning can be performed without moving any other parts, reducing the chance of maintenance personnel coming into contact with live parts inside the cabinet or with unfamiliar internal structures, reducing the risk of accidental contact and the psychological pressure of operation. The design of the cooling mechanism 3 makes the internal layout of the cabinet 1 more spacious, which is conducive to heat dissipation and insulation design, and also makes internal wiring and maintenance easier. Only the power supply connected to the movable drawer 4 to control multiple cooling fans 6 needs to be disconnected, without completely disconnecting the internal circuit of the cabinet, which can effectively avoid losses caused by the shutdown of electrical equipment.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any 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.
