Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to a low-voltage harmonic suppression module structure. Background Technology

[0002] Low-voltage harmonic suppression modules can be used to improve power quality in power systems, especially by suppressing harmonic pollution in low-voltage power systems to improve equipment and system performance. Harmonics are components in current or voltage whose frequency is an integer multiple of the fundamental frequency, typically generated by nonlinear loads (such as frequency converters, UPS, uninterruptible power supplies, rectifiers, etc.). Harmonic pollution can affect the stability and efficiency of electrical equipment, and even lead to overheating, damage, or overload. Low-voltage harmonic suppression modules filter out these harmonic components, ensuring the normal operation of the power system. Therefore, these modules also need protection to ensure their proper functioning.

[0003] Existing low-voltage harmonic suppression module structures are not conducive to buffering and damping when subjected to vibration, making it difficult to improve the seismic resistance of low-voltage harmonic suppression module structures. Utility Model Content

[0004] This application provides a low-voltage harmonic suppression module structure to solve the problem that existing low-voltage harmonic suppression module structures are not convenient for buffering and damping when subjected to vibration, making it difficult to improve the seismic resistance of the low-voltage harmonic suppression module structure.

[0005] This application provides a low-voltage harmonic suppression module structure, including a housing. Two sets of crossbars are fixedly connected to the inner wall of the bottom of the housing. Two sets of sliding seats are slidably connected to the surface of the crossbars. A support rod is rotatably connected to the top of the sliding seat. A rotating bolt is fixedly connected to the top of the support rod. A support spring is fixedly connected to one side of the sliding seat. A support plate is fixedly connected to the top of the rotating bolt. Four sets of damping hydraulic rods are fixedly connected in a rectangular array on the bottom surface of the support plate. A buffer spring is sleeved on the surface of the damping hydraulic rod. A capacitor is fixedly connected to one side of the top of the support plate. A reactor is fixedly connected to the other side of the top of the support plate.

[0006] Preferably, four sets of positioning posts are fixedly connected to the inner top wall of the outer shell, and a circuit board is fixedly installed at the bottom of the positioning posts.

[0007] Preferably, a filter is provided on the surface of the circuit board, and an intelligent measurement and control unit is provided on the surface of the circuit board.

[0008] Preferably, a thyristor composite switch is fixedly connected to the inner top wall of the housing, and a display screen is provided on one side of the housing.

[0009] Preferably, a support cover is fixedly connected to the top of the outer casing, two sets of cooling fans are sleeved inside the support cover, and several sets of heat sinks are fixedly connected to the bottom of the support cover.

[0010] Preferably, a side plate is snapped onto one side of the outer casing, and threaded holes are provided on the surfaces of both the side plate and the outer casing, with threaded bolts connected to the internal threads of the threaded holes.

[0011] Preferably, a protective mesh is fixedly connected to the back of the housing, and several sets of wiring plugs are provided on the front of the housing.

[0012] Beneficial effects:

[0013] Considering the existing low-voltage harmonic suppression module structure, it is not convenient to perform buffering and vibration reduction when subjected to vibration, making it difficult to improve the seismic resistance of the low-voltage harmonic suppression module structure.

[0014] When the equipment is subjected to external vibration or vibration generated by the equipment, the vibration is transmitted to the support plate, causing the support plate to slide inside the shell. This, in turn, causes the support plate to press against the rotating bolt, making the rotating bolt rotate at one end of the support rod and push the support rod. The support rod rotates on top of the sliding seat, pushing the sliding seat. Since the rotating bolt and the support plate remain in a fixed position, the sliding seat slides on the surface of the crossbar. This pushes both sets of sliding seats towards the center, causing the support spring to deform and generate elastic force, pushing the two sets of sliding seats in the opposite direction. Simultaneously, when the support plate presses down, the damping hydraulic rod contracts under force, and the buffer spring deforms and generates elastic force. This achieves the effect of buffering and damping the low-voltage harmonic suppression module structure, reducing mechanical fatigue caused by vibration, extending the service life of the low-voltage harmonic suppression module, and for modules containing critical components such as capacitors, it helps reduce component damage caused by vibration and prevent potential accidents.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figure 1-5The low-voltage harmonic suppression module structure shown includes a housing 1. Two sets of crossbars 2 are fixedly connected to the inner wall of the bottom of the housing 1. Two sets of sliding seats 20 are slidably connected to the surface of the crossbars 2. A support rod 21 is rotatably connected to the top of the sliding seat 20. A rotating bolt 22 is fixedly connected to the top of the support rod 21. A support spring 4 is fixedly connected to one side of the sliding seat 20. A support plate 5 is fixedly connected to the top of the rotating bolt 22. Four sets of damping hydraulic rods 23 are fixedly connected in a rectangular array on the bottom surface of the support plate 5. A buffer spring 24 is sleeved on the surface of the damping hydraulic rods 23. A capacitor 7 is fixedly connected to one side of the top of the support plate 5. A reactor 8 is fixedly connected to the other side of the top of the support plate 5.

[0031] When the equipment is subjected to external vibration or vibration generated by the equipment, the vibration is transmitted to the support plate 5, causing the support plate 5 to slide inside the outer shell 1. The support plate 5 then presses the rotating bolt 22, causing the rotating bolt 22 to rotate at one end of the support rod 21 and push the support rod 21. The support rod 21 rotates on the top of the sliding seat 20, causing the support rod 21 to push the sliding seat 20. Since the rotating bolt 22 and the support plate 5 remain in a fixed position, the sliding seat 20 slides on the surface of the crossbar 2. The two sets of sliding seats 20 are pushed towards the center, causing the support spring 4 to deform and generate elastic force, pushing the two sets of sliding seats 20 in the opposite direction. At the same time, when the support plate 5 is pressed down, the damping hydraulic rod 23 is compressed and the buffer spring 24 is deformed and generates elastic force, thereby achieving the effect of buffering and shock absorption of the low-voltage harmonic suppression module structure, reducing mechanical fatigue caused by vibration, and extending the service life of the low-voltage harmonic suppression module. For modules containing key components such as capacitor 7, it helps to reduce component damage caused by vibration and prevent possible accidents.

[0032] Four sets of positioning posts 9 are fixedly connected to the inner top wall of the outer casing 1, and a circuit board 10 is fixedly installed at the bottom of the positioning posts 9.

[0033] The circuit board 10 is installed using the positioning post 9, which enables the circuit board 10 to be installed accurately and stably in the predetermined position. The positioning post 9 can serve as a reference when installing the circuit board 10, allowing installers to quickly and accurately align the circuit board 10 to the correct position, thereby simplifying the installation process and improving production efficiency.

[0034] A filter is provided on the surface of the circuit board 10, and an intelligent measurement and control unit is provided on the surface of the circuit board 10.

[0035] Among them, the filter can effectively eliminate harmonic interference in the power grid, ensure that the power grid voltage ripple is within the specified range, prevent negative impact on electrical equipment, and improve the power quality of the power distribution system by filtering out high-frequency noise in the power system. The intelligent measurement and control unit can intelligently control and manage various signals on the circuit board 10, thereby improving the stability and reliability of the circuit system.

[0036] A thyristor composite switch 11 is fixedly connected to the inner top wall of the housing 1, and a display screen 12 is provided on one side of the housing 1.

[0037] The thyristor composite switch 11 can precisely control the on / off state of the circuit, achieving zero-voltage conduction and zero-current cut-off, ensuring that the circuit will not generate excessive inrush current when connected and disconnected. Through the display screen 12, users can easily operate and set the thyristor composite switch 11, such as adjusting switching parameters and viewing fault information, thereby improving the ease of use and maintainability of the equipment.

[0038] The top of the outer casing 1 is fixedly connected to a support cover 13, and two sets of cooling fans 14 are fitted inside the support cover 13. Several sets of heat sinks 15 are fixedly connected to the bottom of the support cover 13.

[0039] The cooling fan 14 is fixed inside the support cover 13, the heat sink 15 increases the heat contact area inside, and the airflow of the cooling fan 14 exhausts the hot air out of the outer casing 1. Through their cooperation, the hardware is effectively cooled, thereby maintaining the stable performance of the device and extending its service life.

[0040] A side plate 16 is snapped onto one side of the outer casing 1. Both the side plate 16 and the outer casing 1 have threaded holes on their surfaces, and threaded bolts 17 are threaded into the internal threads of the threaded holes.

[0041] The side plate 16 and the threaded holes on the outer shell 1 are aligned, and the side plate 16 and the outer shell 1 are installed by rotating the threaded bolt 17. The side plate 16 facilitates the inspection and replacement of the interior of the outer shell 1 by personnel.

[0042] A protective net 18 is fixedly connected to the back of the outer casing 1, and several sets of wiring plugs 19 are provided on the front of the outer casing 1.

[0043] Among them, the protective net 18 can block external dust and other impurities from entering the equipment, protecting the low-voltage harmonic suppression module structure to operate normally, and the wiring plug 19 facilitates the connection of external equipment to the low-voltage harmonic suppression module structure for processing.

[0044] Working principle: When this low-voltage harmonic suppression module structure is in use, vibration is transmitted to the support plate 5, causing the support plate 5 to slide inside the outer shell 1. The support plate 5 then presses against the rotating bolt 22, causing the rotating bolt 22 to rotate at one end of the support rod 21 and push the support rod 21. The support rod 21 rotates on top of the sliding seat 20, causing the support rod 21 to push the sliding seat 20. Since the rotating bolt 22 and the support plate 5 remain fixed in position, the sliding seat 20 slides on the surface of the crossbar 2. This pushes the two sets of sliding seats 20 towards the center, causing the support spring 4 to deform and generate elastic force, pushing the two sets of sliding seats 20 in the opposite direction. Simultaneously, when the support plate 5 presses down, the damping hydraulic rod 23 contracts under pressure, and the buffer spring 24 deforms and generates elastic force. This achieves the effect of buffering and damping the low-voltage harmonic suppression module structure, reducing mechanical fatigue caused by vibration, and extending the service life of the low-voltage harmonic suppression module. For modules containing key components such as the capacitor 7, this helps reduce component damage caused by vibration and prevents potential accidents.

[0045] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
