Abstract
Description
Technical Field
[0001] This utility model relates to the field of switch cabinet technology, specifically to a fixed switch cabinet with high-efficiency heat dissipation. Background Technology
[0002] Fixed switchgear refers to switchgear where all electrical components (such as circuit breakers and load switches) are permanently installed. Depending on the voltage level and application scenario, fixed switchgear can be divided into high-voltage fixed switchgear and low-voltage fixed switchgear. High-voltage fixed switchgear is commonly used in the high-voltage sections of power systems, such as power plants and substations; while low-voltage fixed switchgear is widely used in various low-voltage power distribution systems, such as factories, shopping malls, and residential buildings.
[0003] Existing fixed switchgear lacks efficient heat dissipation structures during use. For example, the widely applicable intelligent fixed switchgear disclosed in application number CN201820401382.2 suffers from insufficient heat dissipation structures, preventing the timely dissipation of heat generated by electrical equipment during operation. This leads to a continuous rise in internal temperature, which directly affects the performance of electrical equipment, such as reducing the insulation performance of insulating materials, accelerating component aging, and shortening equipment lifespan. Overheating in one fixed switchgear unit can trigger a chain reaction, affecting other connected equipment or the normal operation of the entire power system. In a power system, all equipment is interconnected; a failure in one device can adversely affect the stability of the entire system.
[0004] Therefore, it is necessary to invent a fixed switch cabinet with high-efficiency heat dissipation to solve the above problems. Utility Model Content

A magnetic strip that matches the inner wall of the sliding door is installed on one side of the outer wall of the sliding door.
[0012] 5. Preferably, the overheat protection structure includes an overheat protector and a connecting wire. The overheat protector is installed in the middle of the electrical frame, and the connecting wire is connected through the middle of the outer side of the overheat protector. One end of the connecting wire is inductively connected to the monitoring base.
[0013] Preferably, the bottom of the monitoring base is fixed to the upper side of the outer wall of the cabinet by a mounting base, and alarms are provided on both sides of the monitoring base, and a temperature sensor is provided on the lower front side of the monitoring base.
[0014] Preferably, the heat dissipation structure includes a first heat dissipation fan, a second heat dissipation fan, a dustproof net, and a small fan.

[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0018] This high-efficiency heat dissipation fixed switch cabinet features heat dissipation structures on both sides and the back of the cabinet's outer wall, including heat dissipation windows, radiators, heat dissipation holes, a first heat dissipation fan, and a second heat dissipation fan. These structures together form a comprehensive, multi-layered heat dissipation system, ensuring that the heat generated by the electrical equipment inside the cabinet can be dissipated in a timely and effective manner, preventing equipment damage or performance degradation due to overheating. The design of the internal air inlet further promotes air convection, allowing cool air to smoothly enter the cabinet and form an effective heat exchange with the hot air, improving heat dissipation efficiency. The dustproof net in the heat dissipation structure effectively blocks the entry of external dust and impurities, maintaining the cleanliness of the air inside the cabinet and extending the service life of the electrical equipment and heat dissipation system. The design of the heat dissipation holes and windows also takes into account dust prevention requirements, ensuring that excessive dust is not introduced while dissipating heat.
[0019] The combination of the overheat protection structure and the monitoring base enables real-time monitoring and overheat protection of the cabinet temperature. Once the electrical equipment overheats, the overheat protector will immediately send a signal to the monitoring base through the connection line, triggering the alarm and taking necessary power-off measures through the controller to protect the electrical equipment and the safety of the entire power system. The accurate measurement of the temperature sensor provides reliable data support for intelligent monitoring, making the monitoring process more accurate and timely. Attached Figure Description

One end of the connecting line 402 is inductively connected to the monitoring base 5.
[0029] A monitoring base 5 is installed on the upper side of one side of the outer wall of the cabinet 1. The bottom of the monitoring base 5 is fixed to the upper side of the outer wall of the cabinet 1 by a mounting bracket 501. An alarm 502 is installed on both sides of the monitoring base 5. A temperature sensor 503 is installed on the lower front side of the monitoring base 5. A heat dissipation structure 6 is installed on the upper and lower sides of both sides of the outer wall of the cabinet 1. The heat dissipation structure 6 includes a first heat dissipation fan 601, a second heat dissipation fan 602, a dust filter 603, and a small fan 604. There are two first heat dissipation fans 601, which are located on the upper sides of the inner wall of the cabinet 1 and the lower side of the inner wall of the cabinet 1, respectively. A second cooling fan 602 is provided on both sides. A dustproof net 603 is provided on the outer side of the first cooling fan 601 and the second cooling fan 602.

A controller 9 is provided on the upper side of one side of the outer wall of the cabinet 1, and the controller 9 is located on one side of the monitoring base 5.
[0030] The working principle of this practical application is as follows:
[0031] Refer to the instruction manual appendix Figure 1-5 For this type of high-efficiency heat dissipation fixed switch cabinet, during use, heat dissipation structures 6 are provided on the upper and lower sides of the outer wall of the cabinet body 1, including a first heat dissipation fan 601 and a second heat dissipation fan 602. The first heat dissipation fan 601 is located on the upper side of the inner wall of the cabinet, which exhausts the hot air generated by the electrical equipment upwards. The second heat dissipation fan 602 is located on the lower side of the inner wall of the cabinet, which promotes the entry of cold air, forms convection, and accelerates heat dissipation. The upper and lower back of the cabinet body 1 are respectively provided with upper heat dissipation windows 101 and lower heat dissipation windows 102, which further enhance the heat dissipation effect. The radiator 103 installed in the middle accelerates heat dissipation through heat conduction and convection. An internal air inlet 104 is provided on the upper side of the inner top surface of the cabinet body 1, which allows external cold air to enter the cabinet. Openings are provided on the middle of the outer walls of the cabinet body. The heat dissipation holes 8 serve as auxiliary heat dissipation channels to ensure that hot air is discharged smoothly. The overheat protection structure 4 set in the middle of the electrical rack 2 includes an overheat protector 401 and a connecting line 402. When the electrical equipment overheats, the overheat protector 401 transmits a signal to the monitoring base 5 through the connecting line 402, triggering the alarm 502. The power can be cut off by the controller 9 to prevent equipment damage. The monitoring base 5 monitors the internal temperature of the cabinet in real time through the temperature sensor 503 and transmits the signal to the controller 9. Once the temperature exceeds the preset threshold, the controller 9 will automatically start the cooling fan and other heat dissipation equipment, and trigger the alarm 502 at the same time. The controller 9 is the core of the whole system, responsible for receiving monitoring signals, controlling the operation of the heat dissipation equipment, and can be remotely operated as needed.
[0032] During the use of this device, the electrical equipment is installed on the electrical rack 2, and maintains a suitable operating temperature through the heat dissipation system and overheat protection system. The monitoring base 5 continuously monitors the internal temperature of the cabinet and controls the operation of the heat dissipation equipment through the controller 9 to ensure heat dissipation efficiency. The cleanliness of the cooling fans 601, 602 and the dust filter 603 is checked regularly to ensure that there is no blockage or dust accumulation, so as to ensure the heat dissipation effect. The working status of the overheat protection structure 4 and the monitoring base 5 is checked regularly to ensure that they can trigger alarms and protection measures normally when needed. The inside of the cabinet 1 is cleaned and inspected regularly to ensure the normal operation of the electrical equipment and the effectiveness of the heat dissipation system. Once the alarm 502 sounds, the inside of the cabinet should be checked immediately to confirm whether there is overheating or other abnormalities. According to the actual situation, corresponding measures should be taken, such as turning off the electrical equipment, starting the backup power supply, or contacting professional personnel for maintenance. When it is necessary to access or maintain the electrical equipment, the front of the cabinet can be opened or closed by moving the sliding door 3. The sliding door 3 slides smoothly through the moving groove 301 and the moving strip, and is kept closed by the magnetic strip 302.
