Description

Technical Field

[0001] This utility model relates to the technical field of low-voltage switchgear devices, specifically an energy-saving and environmentally friendly low-voltage switchgear device. Background Technology

[0002] Low-voltage switchgear, also known as low-voltage distribution cabinet, is generally only 400 volts. The main function of low-voltage switchgear is to open, close, control and protect electrical equipment during the power generation, transmission, distribution and energy conversion process of the power system. The main components of low-voltage switchgear include circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers and various protection devices.

[0003] The prior art, disclosed in CN220107349U, provides an energy-saving and environmentally friendly low-voltage switchgear device, relating to the field of low-voltage switchgear. It includes a low-voltage switchgear body, a cabinet baffle, and a partition plate. The low-voltage switchgear body comprises a low-voltage switchgear shell, a cooling fan, a cabinet circuit board, and a ventilation plate. A cooling fan is fixedly connected to the top of one side of the inner wall of the low-voltage switchgear shell. In this energy-saving and environmentally friendly low-voltage switchgear device, a cabinet baffle is rotatably connected to one end of the low-voltage switchgear body via a hinge. Two sets of cabinet baffles are symmetrically arranged at one end of the low-voltage switchgear body. The interior of the low-voltage switchgear body is hollow, and a partition plate is fixedly connected to the center of the interior. During use, two sets of cooling fans are installed inside the low-voltage switchgear body. The cooling fans blow air to generate convection, allowing for air circulation using a smaller motor, thus reducing the internal operating temperature. This method offers better energy-saving performance compared to previous methods using high-power motors for heat dissipation.

[0004] In the aforementioned patent, air convection is mainly generated by blowing cooling fans onto rotating fans. A smaller motor can be used to drive the internal air circulation, which has a better energy-saving effect than the previous method of using high-power motors to drive cooling. However, in use, the blowing of the fan often cannot effectively act on the convection component, so the blades inside the convection component cannot rotate, thus reducing the internal air convection of the energy-saving and environmentally friendly low-voltage switchgear device during operation.

Because the first heat dissipation component is electrically connected to the microcontroller control board, the microcontroller control board can directly control the first heat dissipation component, improving the intelligence of the energy-saving and environmentally friendly low-voltage switchgear device's operation.

[0007] Furthermore, the first heat dissipation component includes a frame fixedly mounted on the outside of the main control box.

This location allows for heat dissipation within the cabinet assembly through both the second and first heat dissipation assemblies, improving the overall heat dissipation of the electronic components inside the energy-saving and environmentally friendly low-voltage switchgear.

[0009] Furthermore, a belt is fitted onto the output shaft of the small motor inside the first heat dissipation component. The end of the belt away from the first heat dissipation component is fitted onto the output shaft of the small motor inside the second heat dissipation component, and the other end of the belt away from the first heat dissipation component is fitted onto the output shaft of the small motor inside the second heat dissipation component. This allows the fan inside the second heat dissipation component to rotate when the fan inside the first heat dissipation component rotates, thereby improving the integrity of the internal structure of the energy-saving and environmentally friendly low-voltage switchgear.

[0010] Furthermore, the bracket assembly includes multiple mounting plates fixedly installed within the cabinet assembly, with side plates fixedly installed on the mounting plates, and placement plates for placing electronic devices fixedly installed within the multiple side plates.

[0011] Furthermore, the convection assembly is located on a side panel near the control assembly, and the convection assembly is used to generate gas convection inside the cabinet assembly.

[0012] Furthermore, the convection assembly includes a cylindrical groove formed on the side plate. A fixing strip is fixedly installed on the side plate at the end of the cylindrical groove away from the control assembly. A fixing shaft is fixedly installed at the center of the fixing strip. A sleeve is rotatably installed on the fixing shaft. Multiple blades are fixedly installed on the sleeve. A concentrating ring is fixedly installed on the side plate at the end of the cylindrical groove near the control assembly. The concentrating ring is a hollow frustum with openings on both sides. The concentrating ring is used to concentrate the air blown towards it. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention features a concentrating ring at the wind direction of an energy-saving and environmentally friendly low-voltage switchgear.

The end of the belt 36 away from the first heat dissipation component 33 is fitted onto the output shaft of the small motor 334 inside the second heat dissipation component 35. The bracket component 4 includes multiple mounting plates 44 fixedly installed inside the cabinet component 1. Side plates 41 are fixedly installed on the mounting plates 44. Placement plates 43 for placing electronic devices are fixedly installed in the multiple side plates 41. The convection component 42 is located near the control component. On the side plate 41 of the control component 3, the convection component 42 is used to generate gas convection inside the cabinet component 1. The convection component 42 includes a cylindrical groove opened on the side plate 41. A fixing strip 423 is fixedly installed on the side plate 41 at the end of the cylindrical groove away from the control component 3. A fixing shaft 422 is fixedly installed at the center of the fixing strip 423. A sleeve 421 is rotatably installed on the fixing shaft 422.

The concentrating ring 425 is a hollow frustum with openings on both sides. The concentrating ring 425 is used to concentrate the air blown towards the concentrating ring 425.

[0018] The working principle of the controller 32 can be divided into four basic steps: input, processing, output, and feedback. First, the controller 32 receives input signals from external devices or users, such as button presses or information detected by sensors. Next, the controller processes the input signals, performs calculations and judgments according to the set algorithms and logic, and then the controller 32 generates corresponding output signals based on the processing results to control the working status and display information of external devices. Since the microcontroller control board inside the controller 32 is a mature existing technology, it is not described in detail in this utility model.

[0019] It should be noted that the electrical components and control components in this application are all connected to an external controller and are all existing technologies. This application has not improved them and does not affect the integrity of this application. Furthermore, the parts not involved or not disclosed in detail are the same as or implemented using existing technologies.

[0020] The temperature sensor 31 operates based on the thermoelectric effect or the resistance temperature detector (RTD) effect. When the temperature changes, the resistance or electromotive force of a material changes, generating an electrical signal. According to the measurement method, temperature sensors can be divided into two main categories: contact and non-contact. Contact sensors sense temperature through direct contact with the object being measured and typically offer high accuracy. Resistance temperature sensors utilize the characteristic that the resistance of metals or semiconductors changes with temperature, calculating the temperature by measuring the resistance value. Therefore, the value within the temperature sensor 31 changes in real time with the temperature inside the cabinet assembly 1. Users can set a preset value within the temperature sensor 31. When the temperature displayed by the temperature sensor 31 reaches the preset value, it sends an electrical signal to the microcontroller control board within the controller 32. Conversely, when the temperature displayed by the temperature sensor 31 falls below the preset value, it also sends an electrical signal to the microcontroller control board within the controller 32, enhancing the intelligence of the energy-saving and environmentally friendly low-voltage switchgear operation.

[0021] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the energy-saving and environmentally friendly low-voltage switchgear are fixed by threads. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the figure. When using the energy-saving and environmentally friendly low-voltage switchgear, the user fixes the electronic components on the placement plate 43 and activates the temperature sensor 31 to monitor the temperature inside the cabinet assembly 1 in real time. When the displayed value in the temperature sensor 31 is higher than its internal set value, the temperature sensor 31 transmits an electrical signal to the microcontroller control board in the controller 32. The microcontroller control board in the controller 32 then directly controls the operation of the small motor 334 inside the first heat dissipation assembly 33. After the small motor 334 starts running, the fan 333 will rotate accordingly. When the fan 334 inside the first heat dissipation assembly 33 rotates... After rotation, the fan in the second heat dissipation component 35 will also rotate due to the action of the belt 36, thereby dissipating heat and cooling the electronic components in the cabinet component 1. When the air blows towards the concentrating ring 425, the concentrating ring 425 will concentrate the air and blow it towards the sleeve 421, causing the blades 424 in the sleeve 421 to rotate, thereby convecting the air in the cabinet component 1 and improving the cooling effect on the electronic components inside the cabinet component 1. When the temperature sensor 31 detects that the temperature inside the energy-saving and environmentally friendly low-voltage cabinet is lower than its internal set value, the small motor 334 will stop running through the above control, so that the fan does not need to be started when the energy-saving and environmentally friendly low-voltage cabinet is in use, improving the overall energy-saving and environmentally friendly operation of the energy-saving and environmentally friendly low-voltage cabinet.

[0022] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
