[0010] In order to facilitate heat dissipation in the AC high-voltage switchgear with intelligent dehumidification and line protection, as a preferred embodiment of the present invention, a heat dissipation groove is provided at the bottom of the front of the cabinet door, and a second filter screen is fixedly connected to both sides of the outer surface of the cabinet.

[0011] In order to make it easy to cover the second filter screen in the AC high-voltage switchgear with intelligent dehumidification and line protection, as a preferred embodiment of the present invention, a baffle is slidably connected to the inner wall of the cabinet near the second filter screen, and a magnetic block is fixedly connected to the edge of the inner side of the baffle.

[0012] In order to make the AC high-voltage switchgear with intelligent dehumidification and line protection easy to install electrical equipment, as a preferred embodiment of the present invention, both sides of the inner side of the cabinet are fixedly connected with a bracket, and the number of the brackets is several.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This AC high-voltage switchgear, equipped with intelligent dehumidification and line protection, utilizes a heat exchanger, fixed pipes, air outlets, blades, and a swing mechanism. The heat exchanger condenses moisture in the humid air inside the cabinet into water droplets and discharges them outside, effectively reducing humidity and preventing condensation caused by high humidity. Simultaneously, it efficiently recovers heat from the air during dehumidification, discharging the recovered heat into the cabinet through the fixed pipes and multiple evenly distributed air outlets. The swing mechanism rotates the blades during dehumidification, changing the direction of the hot air outlet and expanding the coverage area within the cabinet. This ensures more uniform dehumidification across all areas, preventing localized poor dehumidification and improving overall dehumidification efficiency.

[0018] 2. This AC high-voltage switchgear, equipped with intelligent dehumidification and line protection, utilizes a first filter plate, a second filter plate, and a baffle. The first filter plate effectively filters dust, impurities, and other particulate matter from the air entering the heat exchanger, ensuring the normal operation and service life of the heat exchanger. The magnetic connection via a magnetic ring makes the installation and removal of the first filter plate very convenient. The second filter plate increases the airflow area between the cabinet and the outside air, creating good air convection and effectively reducing the temperature inside the cabinet. The baffle allows for flexible obstruction of the second filter plate, facilitating operation by personnel.

[0019] 3. This AC high-voltage switchgear, equipped with intelligent dehumidification and line protection, utilizes a conical sleeve, nut, winding rod, and coil spring. By tightening the nut, the lines can be securely clamped within the conical sleeve, preventing loosening or detachment and improving the equipment's protective performance. Simultaneously, it allows the equipment to accommodate various line specifications, enhancing its versatility and applicability. Winding the lines onto the winding rod neatly organizes messy wiring, preventing tangling and cross-linking within the cabinet, thus reducing friction and wear between lines and strengthening line protection. When a line is pulled out, the coil spring automatically retracts, pulling the winding rod back the line, maintaining its neatness and order, reducing manual wiring work, and improving the equipment's ease of use and work efficiency.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example

[0031] Please see Figures 1-7The present invention provides the following technical solution: an AC high-voltage switchgear with intelligent dehumidification and line protection, comprising a cabinet body 1, a cabinet door 2 hinged to the front of the cabinet body 1, a heat exchanger 3 fixedly connected to the bottom of the inner side of the cabinet door 2, a fixed pipe 4 fixedly connected to one side of the upper surface of the heat exchanger 3, an air outlet 5 opened on the outer surface of the fixed pipe 4, a housing 6 fixedly connected to the middle of the inner side of the cabinet body 1, a rotating rod 7 rotatably connected to the inner top wall of the housing 6, the rotating rod 7 passing through the housing 6 and rotatably connected to the housing 6 through a bearing, a blade 8 fixedly connected to the outer surface of the rotating rod 7 near the housing 6, a swing mechanism 9 provided at the top of the outer surface of the housing 6, a connecting arm 10 fixedly connected to the top of the outer surface of the rotating rod 7, and the connecting arm 10 and the swing mechanism 9 being hinged.

[0032] In a specific embodiment of the present invention, through the arrangement of heat exchanger 3, fixed pipe 4, air outlet 5, blades 8, and swing mechanism 9, cabinet 1 provides a closed protective space for the internal electrical components, preventing external dust, moisture, debris, etc., from contaminating or damaging the electrical components, thus improving the reliability and service life of the equipment. Cabinet door 2 is hinged to the front of cabinet 1 to close cabinet 1. Heat exchanger 3 is installed on the inner side of cabinet door 2, allowing operators to easily open cabinet door 2 for equipment inspection, maintenance, and operation, improving the convenience of equipment maintenance. Heat exchanger 3 is used in conjunction with temperature and humidity sensors. Temperature and humidity sensors are key components for realizing intelligent dehumidification function. They can monitor the temperature and humidity in the environment in real time and transmit this data to the control system, thereby realizing automated dehumidification control. Temperature and humidity sensors are usually installed in a suitable location inside the cabinet, such as near the electrical components, to ensure accurate monitoring of critical parts. Temperature and humidity sensors are connected to the control unit via data cables. The control unit automatically controls the operation of the dehumidification device based on preset temperature and humidity thresholds and real-time data provided by the sensors. The heat exchanger 3 condenses the moisture in the humid air inside the cabinet into water droplets and discharges them outside the cabinet, effectively reducing the humidity inside the cabinet and preventing condensation caused by high humidity, thereby protecting the insulation performance of electrical components. At the same time, the heat exchanger 3 can efficiently recover heat from the air during the dehumidification process, reducing energy loss and improving the energy utilization efficiency of the equipment. The recovered heat is transported through the fixed pipe 4 and then discharged through multiple evenly distributed air outlets 5. The swing mechanism 9 is connected to the rotating rod 7 through the connecting arm 10. During the dehumidification process, it drives the blades 8 to rotate, changing the direction of the hot air outlet, thereby expanding the coverage area of ​​the cabinet space during dehumidification, so that all areas inside the cabinet can be dehumidified more evenly, avoiding poor local dehumidification effect and improving dehumidification efficiency.

[0033] Specifically, the swing mechanism 9 includes a bracket 901 fixed to the top of the outer surface of the housing 6, a motor 902 fixedly connected to the upper surface of the bracket 901, and a rotating shaft 903 fixedly connected to the output end of the motor 902.

[0034] In this embodiment: the bracket 901 provides stable support for the motor 902, ensuring that the motor 902 will not shake or shift during operation. The motor 902 is the power source of the swing mechanism 9. Through the rotating shaft 903 at its output end, it transmits power to subsequent components such as the crank 904 and connecting rod 905, driving the entire swing mechanism 9 to work, which improves the automation level and work efficiency of the equipment. The speed and direction of the motor 902 can be precisely controlled by the control circuit, thereby realizing the precise adjustment of the swing frequency and direction of the swing mechanism 9. This allows the equipment to flexibly adjust the swing action according to the humidity and dehumidification requirements in the cabinet, achieving the best dehumidification effect and improving the control accuracy and intelligence level of the equipment.

[0035] Specifically, one end of the rotating shaft 903 is fixedly connected to a crank 904, one end of the crank 904 is rotatably connected to a connecting rod 905, one end of the connecting rod 905 is rotatably connected to a slide rod 906, the slide rod 906 is hinged to the connecting arm 10, and a sliding sleeve 907 is fixedly connected to the upper surface of the housing 6 near the slide rod 906, the sliding sleeve 907 is slidably connected to the slide rod 906.

[0036] In this embodiment, the rotational motion of the motor 902 is sequentially converted into the reciprocating linear motion of the slide rod 906 via the rotating shaft 903, crank 904, and connecting rod 905. The slide rod 906 is then hinged to the connecting arm 10, causing the connecting arm 10 to swing. This ensures the accuracy and reliability of the swing motion. By changing parameters such as the length of the crank 904, the length of the connecting rod 905, and the stroke of the slide rod 906, the swing amplitude and frequency of the connecting arm 10 can be adjusted. This allows the equipment to flexibly adjust the swing motion parameters according to different dehumidification requirements and working environments to achieve the best dehumidification effect, thus improving the adaptability and flexibility of the equipment.

[0037] Specifically, a magnetic ring 11 is fixedly connected to the edge of the front side of the heat exchanger 3, and a first filter plate 12 is magnetically connected to the front side of the heat exchanger 3 through the magnetic ring 11.

[0038] In this embodiment, the first filter screen 12 can effectively filter dust, impurities and other particulate matter in the air entering the heat exchanger 3, thereby ensuring the normal operation and service life of the heat exchanger 3. The magnetic connection of the magnetic ring 11 makes the installation and disassembly of the first filter screen 12 very convenient, greatly improving the maintenance convenience and work efficiency of the equipment.

[0039] Specifically, a heat dissipation groove 13 is provided at the bottom of the front of the cabinet door 2, and a second filter screen 14 is fixedly connected to both sides of the outer surface of the cabinet body 1.

[0040] In this embodiment: the multiple inclined heat dissipation slots 13 facilitate the dissipation of heat generated during the operation of the heat exchanger 3. The second filter plate 14 increases the airflow area between the cabinet 1 and the outside air, allowing the heat of the cabinet 1 to dissipate to the outside environment more quickly, forming good air convection, effectively reducing the temperature inside the cabinet, and preventing electrical components from being damaged due to overheating. At the same time, the second filter plate 14 filters air impurities, preventing dust and debris from the outside air from entering the cabinet, ensuring the cleanliness of the cabinet environment, reducing dust pollution and impact on electrical components, and improving the reliability and stability of the equipment.

[0041] Specifically, a baffle 15 is slidably connected to the inner wall of the cabinet 1 on the side near the second filter screen 14, and a magnetic block 16 is fixedly connected to the edge of the inner side of the baffle 15.

[0042] In this embodiment, the baffle 15 can slide on the inner wall of the cabinet 1 to flexibly block the second filter screen 14. When the external environment of the equipment is good, the baffle 15 can be opened to expand the heat dissipation range of the cabinet 1 and facilitate the operation of the operator. The magnetic block 16 enables the baffle 15 to be stably fixed on the inner wall of the cabinet 1 after sliding to the designated position, and it will not shift when there is no external force interference.

[0043] Specifically, both sides of the inner side of the cabinet 1 are fixedly connected with card seats 17. There are several card seats 17, which are evenly fixed to the inner side of the cabinet 1 in a horizontal array. A support plate 18 is snapped into the inside of the card seat 17, and a through hole 19 is opened on the upper surface of the support plate 18.

[0044] In this embodiment, electrical equipment is installed on the support plate 18, and the support plate 18 is fixed to the inner side of the cabinet 1 using the card holder 17. The position and number of support plates 18 can be flexibly adjusted according to the size and installation requirements of different equipment to achieve stable installation of various electrical equipment and increase the scope of use.

[0045] Specifically, a conical sleeve 20 is fixedly connected to the back of the cabinet 1, and a nut 21 is threaded onto the outer surface of the conical sleeve 20.

[0046] In this embodiment: the tapered sleeve 20 provides a convenient channel for the line to enter, reducing the friction and resistance encountered by the line during the entry process, reducing the risk of line damage. By tightening the nut 21, the line can be firmly clamped in the tapered sleeve 20 to prevent the line from loosening or falling off, thus improving the protective performance of the equipment. At the same time, it enables the equipment to be compatible with various specifications of lines, improving the versatility and applicability of the equipment and reducing the operating cost of the equipment.

[0047] Specifically, a fixing block 22 is fixedly connected to the edge of the upper surface of the support plate 18, and a winding rod 23 is rotatably connected to the inner side of the fixing block 22.

[0048] In this embodiment: by winding the wires around the winding rod 23, the messy wires can be organized in an orderly manner, avoiding the wires from tangling and crossing each other in the cabinet, thereby reducing friction and wear between the wires, strengthening the protection of the wires, and extending the service life of the wires. At the same time, the neat layout of the wires also helps to improve the aesthetics and cleanliness of the equipment.

[0049] Specifically, a fixed seat 24 is rotatably connected to the outer surface of the winding rod 23 away from the fixed block 22. The fixed seat 24 is fixedly connected to the support plate 18. A coil spring 25 is fixedly connected to the inner side of the fixed seat 24. One end of the coil spring 25 is fixedly connected to the winding rod 23.

[0050] In this embodiment, the coil spring 25 enables the winding rod 23 to have an automatic reset function. When the line is pulled out, the coil spring 25 will automatically retract, driving the winding rod 23 to retract the line, keeping the line neat and orderly, reducing the workload of manually tidying the line, and improving the ease of use and work efficiency of the equipment.

[0051] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0052] The working principle and usage process of this invention: During use, the AC high-voltage switchgear with intelligent dehumidification and line protection uses temperature and humidity sensors to monitor the temperature and humidity inside the cabinet in real time. When the humidity exceeds a preset threshold, the control unit activates the heat exchanger 3. The heat exchanger 3 condenses the moisture in the humid air inside the cabinet into water droplets and discharges them outside the cabinet, effectively reducing the humidity and preventing condensation caused by high humidity. Simultaneously, the heat exchanger 3 recovers heat from the air during dehumidification. The recovered heat is discharged into the cabinet through a fixed pipe 4 and multiple evenly distributed air outlets 5. The swing mechanism 9 is connected to the rotating rod 7 via a connecting arm 10, driving the blades 8 to rotate during dehumidification, changing the direction of the hot air outlet and ensuring more uniform dehumidification in all areas of the cabinet. The first filter plate 12 effectively filters dust, impurities, and other particulate matter from the air entering the heat exchanger 3. The heat dissipation trough 1... 3. To facilitate the dissipation of heat generated during the operation of heat exchanger 3, the second filter plate 14 increases the airflow area between cabinet 1 and the outside air, allowing the heat of cabinet 1 to dissipate to the outside environment more quickly, forming good air convection and effectively reducing the temperature inside the cabinet. The baffle 15 can flexibly block the second filter plate 14. Electrical equipment is installed on the support plate 18, and the support plate 18 is fixed to the inner side of cabinet 1 using the bracket 17. The position and number of support plates 18 can be flexibly adjusted according to the size and installation requirements of different equipment. The conical sleeve 20 and nut 21 provide a convenient channel for the entry of wires, etc. The wires are wound on the winding rod 23 to prevent the wires from tangling and crossing each other inside the cabinet, thereby reducing friction and wear between the wires and strengthening the protection of the wires. When the wires are pulled out, the coil spring 25 will automatically retract, driving the winding rod 23 to retract the wires, keeping the wires neat and orderly.
