[0002] During microgrid operation, due to the inherent characteristics of the microgrid and the use of power electronic devices, harmonics within the microgrid become prominent. Harmonics pollute the power quality of the microgrid. The main hazards caused by harmonics are increased additional harmonic losses in the microgrid, additional thermal effects, and the tendency to cause some protective equipment to malfunction. To this end, existing technologies often use harmonic suppression compensation to filter out harmonics in the power grid.

[0003] Traditional harmonic control electrical cabinets are made of steel and are used to install harmonic control components for normal operation. A variety of harmonic control components are installed in the cabinet. When a harmonic control component is damaged and needs to be repaired or replaced, it is inconvenient for maintenance personnel to repair or replace the harmonic control component due to the large number of components and wiring harnesses in the cabinet and the small space. In addition, the multiple components in the cabinet have poor heat dissipation.

[0004] Therefore, it is necessary to provide a harmonic control compensation cabinet to solve the above technical problems. Utility Model Content

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] A harmonic control compensation cabinet includes a cabinet body 1, an opening and closing module 2, a support plate 3, and a heat dissipation module 4;

[0032] The opening and closing module 2 includes two convex plates 22, which are respectively fixedly connected to one side of the cabinet 1. The two ends of the bidirectional screw rod 26 are movably connected to the corresponding convex plates 22. The bidirectional screw rod 26 is provided with two sections of threads with opposite thread directions. One end of the bidirectional screw rod 26 passes through the corresponding convex plate 22. One end of the bidirectional screw rod 26 is fixedly connected to the center of the turntable 27. The bidirectional screw rod 26 is respectively threadedly connected to the two sliders 25. The two sides of the two sliders 25 are respectively connected to the corresponding pair of connecting rods 24 through pin hinges.

[0033] One end of a corresponding pair of connecting rods 24 is connected to the corresponding square guide rods 23 through a pin hinge, and a corresponding pair of square guide rods 23 pass through the corresponding square sleeves 21 respectively. A corresponding pair of square sleeves 21 are fixedly connected to one side of the cabinet body 1, and one end of a corresponding pair of square guide rods 23 is connected to the corresponding rocker rods 28 through a pin hinge, and a corresponding pair of rocker rods 28 are connected to the corresponding L-shaped cabinet doors 29 through a pin hinge. One end of the two L-shaped cabinet doors 29 are connected to the two sides of the cabinet body 1 through a pin hinge.

[0034] The heat dissipation module 4 includes a through slot 45, which is arranged on the lower side of the cabinet 1. The inner wall of the through slot 45 is fixedly connected to the two ends of the square plate 43, and the upper side of the square plate 43 is fixedly connected to the motor 44. The output shaft of the motor 44 is fixedly connected to the center of the fan blade 42, and the edge of the through slot 45 is fixedly connected to the edge of the filter cover 41.

[0035] A group of support columns 32 are fixedly connected to the lower side of the cabinet 1.

[0036] A group of support columns 32 are respectively fixedly connected to the support plates 3 .

[0037] The upper sides of the support plates 3 are fixedly connected to the reinforcement blocks 31 .

[0038] The reinforcement block 31 is fixedly connected to the cabinet 1 .

[0039] Working principle: There are multiple harmonic control components installed in the cabinet 1. When one of the harmonic control components is damaged and needs to be repaired or replaced, the turntable 27 is rotated, and the turntable 27 drives the bidirectional screw rod 26 to rotate. The bidirectional screw rod 26 drives the corresponding slider 25 to slide. The two sliders 25 drive the corresponding pair of connecting rods 24 to swing. The corresponding pair of connecting rods 24 drive the corresponding square guide rods 23 to extend along the square sleeve 21, so that the corresponding pair of square guide rods 23 drive the swing rod 28 to swing, and the corresponding pair of swing rods 28 drive the corresponding L-shaped cabinet door 29 to open. Figure 2 As shown, the harmonic control components in the cabinet 1 are exposed, and the rotation of the turntable 27 is stopped at this time, and a certain harmonic control component is started to be repaired or replaced;

[0040] When a harmonic control component is repaired or replaced, the turntable 27 is rotated in the opposite direction. The movement direction of some parts of the device is opposite to the above movement direction, so it is not repeated here. The two L-shaped cabinet doors 29 are closed. Figure 1As shown, when the temperature inside the cabinet 1 is high, the motor 44 is started, and the motor 44 drives the fan blades 42 to rotate, so that the fan blades 42 blow the external air through the filter cover 41 into the through groove 45 and the cabinet 1, thereby cooling the harmonic control components in the cabinet 1, effectively avoiding damage to the harmonic control components, and increasing the service life of the harmonic control components. At the same time, the setting of the filter cover 41 can filter out large particles of impurities in the air, etc., and play a certain dust-proof role for the harmonic control components.

[0041] Beneficial effect: When one of the harmonic control components is damaged and needs to be repaired or replaced, the L-shaped cabinet door 29 is opened or closed through the opening and closing module 2, so that the harmonic control components in the cabinet 1 are exposed, and a harmonic control component can be repaired or replaced, which is convenient and practical. When the temperature in the cabinet 1 is high, the heat dissipation module 4 is used to make the fan blades 42 blow the external air through the filter cover 41 into the through groove 45 and the cabinet 1, so as to cool the harmonic control components in the cabinet 1, effectively avoid damage to the harmonic control components, and increase the service life of the harmonic control components. At the same time, the setting of the filter cover 41 can filter out large particles of impurities in the air, and play a certain dust-proof role for the harmonic control components.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
