Description

Technical Field

[0001] The present invention relates to the technical field of switchgear, and particularly to an intelligent manual and electric integrated high-voltage switchgear. Background Art

[0002] In the power transmission and distribution link of the power system, as one of the core equipment, the high-voltage switchgear undertakes important functions such as power control, protection and distribution. The stability, reliability and intelligence level of its operation are directly related to the safe and efficient operation of the power system. There are many limitations in the structural design and operation mode of traditional high-voltage switchgear. In the early stage, most switchgears adopted a fixed structure. Once the internal core components such as circuit breakers were installed, it was difficult to move them flexibly. When maintenance, repair or replacement was required, the entire power supply circuit often needed to be interrupted. This not only made the operation cumbersome and time-consuming, but also had a serious impact on the continuity of power supply, bringing inconvenience to industrial production and residential life. With the development of the power industry, the handcart type high-voltage switchgear has gradually been applied, and components such as circuit breakers inside it can move with the handcart, which improves the convenience of maintenance to a certain extent. However, there are still some problems that need to be improved.

[0003] After retrieval, the invention patent with the publication number CN113824034A discloses a manual and electric integrated high-voltage switchgear, which includes a switchgear body. The switchgear body is provided with a handcart room and a circuit breaker room; a manual and electric integrated chassis truck is arranged in the handcart room, and a vacuum circuit breaker is arranged in the circuit breaker room; the chassis truck includes a frame, a positioning mechanism, a motor, a transmission mechanism, a丝杆, a pulley fixed on the frame and a nut gear rotatably arranged on the frame; the motor is connected to the nut gear through the transmission mechanism, and the nut gear is connected in cooperation with the丝杆; a track cooperating with the pulley is arranged in the switchgear body; the transmission mechanism includes an electric clutch mechanism and a transmission gear set, and the motor drives the transmission gear set to rotate through the electric clutch mechanism, and the transmission gear set drives the nut gear to rotate. This invention simplifies the structure and reduces the manufacturing cost.

[0004] However, when in use, it can only be translated and cannot be adjusted in height and angle, which results in limited use space and makes it difficult to meet the use requirements in different scenarios. In addition, in terms of heat dissipation performance, due to the dense internal components and large power of the switchgear body, a large amount of heat will be generated during operation. If the heat dissipation is not timely, it is extremely easy to cause the cabinet temperature to be too high, leading to insulation aging, component performance degradation or even short circuit and other faults. Its heat dissipation effect is not ideal and it is difficult to meet the heat dissipation requirements under high-power and high-load operation. Summary of the Invention

[0005] The purpose of the present invention is to propose an intelligent manual and electric integrated high-voltage switchgear to solve the problems of single adjustment position and unsatisfactory heat dissipation effect in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent manual-electric integrated high-voltage switchgear, comprising a switchgear body, wherein a cabinet door is hinged to the switchgear body, characterized in that a first baffle and a second baffle are fixedly connected inside the switchgear body respectively, a handcart compartment is formed between the first baffle and the second baffle inside the switchgear body, and a mobile vehicle is installed inside the switchgear body by means of a mechanical arm, wherein a circuit breaker is installed on the mobile vehicle.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Example, refer to Figure 1-8 The intelligent manual / electric integrated high-voltage switchgear includes a switchgear body 1, with a hinged door 27 on the switchgear body 1. A mounting bracket 32 ​​is installed on the bottom surface of the switchgear body 1, and the mounting bracket 32 ​​has multiple mounting holes. This allows the switchgear to be stably installed on the ground or other foundations, facilitating installation. A first baffle 2 and a second baffle 3 are fixedly connected inside the switchgear body 1, forming a handcart compartment between the first baffle 2 and the second baffle 3 inside the switchgear body 1. A mobile trolley 9 is mounted inside the switchgear body 1 via a robotic arm, and a circuit breaker 10 is installed on the mobile trolley 9.

[0023] Specifically, a separate handcart compartment is separated within the main body 1 of the switchgear by a first baffle 2 and a second baffle 3, providing dedicated working space for the circuit breaker 10 and the mobile vehicle 9, thereby effectively avoiding mutual interference with other components inside the main body 1 of the switchgear. The hinged structure between the main body 1 of the switchgear and the cabinet door 27 ensures the flexibility of opening and closing the cabinet door 27, and also creates a good sealing environment when closed, reducing the corrosion of internal equipment by external dust and moisture.

[0024] The switch cabinet body 1 is internally fixedly connected to a mounting plate 5. The robotic arm includes a fixed plate 6 mounted on the mounting plate 5. A first adjusting arm 7 is fixedly connected to the fixed plate 6. A second adjusting arm 8 is mounted on the other end of the first adjusting arm 7. The second adjusting arm 8 is fixedly connected to the mobile vehicle body 9 through the mounting plate.

[0025] Mounting plate 5 provides a stable mounting base for the robotic arm, ensuring that the robotic arm will not sway or shift during the movement of the moving vehicle 9 and the circuit breaker 10. The first adjusting arm 7 works in conjunction with the second adjusting arm 8, enabling the robotic arm to move with multiple degrees of freedom, thereby achieving flexible rotation and position adjustment of the moving vehicle 9 in three-dimensional space, which can meet the precise position requirements of the circuit breaker 10 under different working conditions.

[0026] It should be noted that the robotic arm used is existing technology, similar to a display screen bracket. The innovation of this application lies in integrating mature robotic arm technology with the overall structure of the switch cabinet, thereby optimizing the equipment's functions. On the other hand, existing robotic arm technology has been validated by the market over a long period of time and has high reliability and stability, ensuring the overall performance of the switch cabinet.

[0027] Furthermore, the main body 1 of the switchgear has two support plates 15 fixedly connected inside for stabilizing the moving vehicle body 9. The front end of each support plate 15 is set as a slope, and multiple ball bearings 16 are installed on each support plate 15. Limiting strips 17 are fixedly connected to each support plate 15, and the moving vehicle body 9 is placed between the two limiting strips 17. Multiple reinforcing ribs 18 are fixedly connected between the support plate 15 and the main body 1 of the switchgear.

[0028] The symmetrical distribution of the two support plates 15 provides a stable support surface for the mobile vehicle body 9, ensuring that it does not tilt during placement and operation. The sloping design at the front end of the support plate 15 ensures a smooth transition when the mobile vehicle body 9 enters or exits the support plate 15. The ball bearings 16 convert the sliding friction between the mobile vehicle body 9 and the support plate 15 into rolling friction, greatly reducing frictional resistance and making the movement of the mobile vehicle body 9 more effortless and smooth. The limiting strip 17 restricts the lateral position of the mobile vehicle body 9, preventing lateral deviation during movement or operation and ensuring the accuracy of its position. The reinforcing ribs 18 enhance the connection strength between the support plate 15 and the switch cabinet body 1, improving the load-bearing capacity of the support plate 15 and ensuring that it does not deform during long-term use.

[0029] Two fixed cylinders 29 are fixedly connected to the cabinet door 27. A push rod 30 is slidably connected inside each fixed cylinder 29. A push block for pressing the moving carriage 9 is fixedly connected to the other end of each push rod 30. A spring 31 is fitted onto each push rod 30, with one end of each spring fixedly connected to the push block and the other end fixedly connected to the fixed cylinder 29. The fixed cylinders 29, push rods 30, push blocks, and springs 31 on the cabinet door 27 form an elastic pressing mechanism. When the cabinet door 27 is closed, the elastic force of the springs 31 pushes the push rods 30 and push blocks forward, firmly pressing the moving carriage 9 and preventing displacement of the moving carriage 9 due to vibration during equipment operation.

[0030] The further advantages of the above-mentioned approach are: the combination of support plate 15, ball bearings 16, and limiting strip 17 ensures the stability and accuracy of the movement and placement of the mobile carriage 9, reduces operational difficulty, and improves work efficiency. The reinforcing ribs 18 enhance the structural strength of the support plate 15, extending the service life of the equipment. Secondly, after the cabinet door 27 is closed, the mobile carriage 9 is effectively secured, preventing vibrations during equipment operation from affecting its position, ensuring the normal operation of core components such as the circuit breaker 10, and improving the overall reliability of the switchgear.

[0031] In this invention, several ventilation holes are provided on the first baffle 2 and the second baffle 3. An isolation baffle 4 is fixedly connected inside the switch cabinet body 1. An oil storage chamber is formed between the inside of the switch cabinet body 1 and the isolation baffle 4. An air distribution chamber is formed between the isolation baffle 4 and the first baffle 2. A heat dissipation duct 19 is provided on the switch cabinet body 1. The top end of the heat dissipation duct 19 is connected to the top of the switch cabinet body 1. The bottom end of the heat dissipation duct 19 penetrates the bottom surface of the switch cabinet body 1 and is connected to the air distribution chamber. A fan 20 is installed on the heat dissipation duct 19.

[0032] The vents on the first baffle 2 and the second baffle 3 provide channels for air circulation inside the switchgear body 1, allowing air to flow between different areas such as the handcart compartment and the equipment compartment, facilitating heat dissipation. The isolation baffle 4 separates the interior of the switchgear body 1 into an independent oil storage chamber, providing oil storage space. This oil storage chamber is used to store insulating oil, such as transformer insulating oil used in wet transformers.

[0033] The uniform air distribution chamber ensures that the cooling air entering the switchgear body 1 is evenly distributed, preventing overheating in localized areas due to poor air circulation. The heat dissipation duct 19 connects the top and bottom of the switchgear body 1 and communicates with the uniform air distribution chamber, forming a complete air circulation channel. A fan 20, installed on the heat dissipation duct 19, provides power for the air circulation. Through the operation of the fan 20, hot air is extracted from inside the switchgear body 1, and cooled air is introduced into the switchgear body 1, achieving heat dissipation and cooling inside the switchgear body 1.

[0034] In this invention, multiple heat-conducting rods 21 are fixedly connected to the heat dissipation duct 19, and all heat-conducting rods 21 are disposed inside the oil storage chamber. This fully utilizes the heat absorption characteristics of the insulating oil in the oil storage chamber. When hot air flows in the heat dissipation duct 19, heat is transferred to the heat-conducting rods 21 through the wall of the heat dissipation duct 19, and the heat-conducting rods 21 then transfer the heat to the insulating oil in the oil storage chamber, thereby cooling the hot air. The arrangement of the heat-conducting rods 21 increases the heat dissipation area, improves heat transfer efficiency, and enhances the heat dissipation effect.

[0035] Furthermore, the switchgear body 1 is provided with an oil inlet and an oil outlet communicating with the oil storage chamber. The oil inlet is internally threaded with a first sealing cap 22, and the oil outlet is internally threaded with a second sealing cap 23. The oil inlet and outlet facilitate the addition or removal of oil from the oil storage chamber. When the insulating oil in the oil storage chamber is insufficient, the first sealing cap 22 can be opened to add insulating oil to the chamber through the oil inlet. When it is necessary to replace the insulating oil in the oil storage chamber or clean the chamber, the second sealing cap 23 can be opened to drain the oil through the oil outlet. The threaded connection of the first sealing cap 22 and the second sealing cap 23 provides good sealing performance, effectively preventing leakage of insulating oil from the oil storage chamber. It also prevents external dust and impurities from entering the oil storage chamber through the oil inlet and outlet, ensuring the cleanliness of the interior of the oil storage chamber.

[0036] In this invention, an equipment compartment is formed between the main body 1 of the switchgear and the second baffle 3. Electrical components 24 are installed in the equipment compartment. The equipment compartment provides independent installation space for the electrical components 24, isolating them from the handcart compartment, reducing interference between different components, and facilitating equipment maintenance and repair. A status panel 25 and indicator lights 26 are installed on the main body 1 of the switchgear. The status panel 25 can display various operating parameters of the switchgear in real time, such as voltage, current, and power, allowing staff to intuitively understand the operating status of the equipment. The indicator lights 26 quickly provide feedback on the working status of the equipment through different colors and on / off states, such as normal operation and fault alarm, facilitating timely detection and handling of problems by staff.

[0037] In this invention, an observation window 28 is embedded in the cabinet door 27. The observation window 28 on the cabinet door 27 is made of transparent material, so that the staff can observe the inside of the switch cabinet body 1 without opening the cabinet door 27. This not only facilitates the daily inspection of the equipment, but also reduces the impact on the internal environment of the switch cabinet body 1 caused by frequent opening of the door.

[0038] A handle 11 is fixedly connected to the mobile carriage 9, allowing workers to easily pull it. A temperature controller 12 is installed on the mobile carriage 9, which monitors the temperature of the carriage compartment in real time and adjusts heat dissipation accordingly, ensuring the temperature inside the compartment remains within a suitable range. A gooseneck tube 13 is fixedly connected to the mobile carriage 9, with a light 14 installed at the other end. The gooseneck tube 13 has good flexibility and malleability, allowing it to be bent and adjusted at any angle, enabling the light 14 to precisely illuminate any area inside the switch cabinet body 1. This provides ample light for equipment inspection and maintenance, improving work convenience and efficiency.

[0039] This invention utilizes a fixed frame 32 at the bottom of the switchgear body 1, which is fixed to the mounting base through mounting holes. A mechanical arm is used to install a mobile vehicle 9 inside the switchgear body 1. The mechanical arm consists of a fixed plate 6, a first adjusting arm 7, and a second adjusting arm 8. Specifically, the first adjusting arm 7 is mounted on the mounting plate 5 through the fixed plate 6. When it is necessary to move the circuit breaker 10 and the mobile vehicle 9, the joint structure of the first adjusting arm 7 and the second adjusting arm 8 can be used to achieve multi-angle rotation, so that the mobile vehicle 9 can move flexibly in the handcart compartment inside the switchgear body 1. In this way, the mobile vehicle 9 can also be moved out of the switchgear body 1 for maintenance. After maintenance, during its reset process, the slope at the front end of the support plate 15 can guide the mobile vehicle 9 to be placed stably. The ball bearings 16 can reduce the friction of the contact surface, and the limit strip 17 can limit the lateral displacement of the mobile vehicle 9, thereby ensuring that the placement process is stable and reliable. When the cabinet door 27 is closed, the top rod 30 in the fixed cylinder 29 can push the push block to press the mobile vehicle 9 under the elastic force of the spring 31, and fix it firmly.

[0040] In addition, heat dissipation can be carried out inside the switch cabinet body 1. After the fan 20 is started, the heat dissipation duct 19 can form an airflow channel to draw hot air from the top of the switch cabinet body 1 and transport it. During this process, the insulating oil in the oil storage chamber can absorb the heat in the heat dissipation duct 19 through the heat conduction rod 21 and cool it. Then it can be sent back into the switch cabinet body 1 through the uniform air chamber for circulation. The temperature controller 12 can monitor the temperature of the handcart compartment in real time. If the temperature is abnormal, the fan 20 will be triggered to adjust the speed and other temperature control actions to ensure that the ambient temperature is suitable. During the operation of the equipment, its operating status is displayed by the status panel 25 on the switch cabinet body 1 and the indicator light 26 indicates the fault or normal status. The staff can directly observe the internal situation through the observation window 28 on the cabinet door 27. The gooseneck tube 13 on the mobile car body 9 can be bent at will, driving the lighting lamp 14 to accurately illuminate the maintenance area and improve the convenience of maintenance.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
