[0002] Static Var Generator, also known as Static Var Generator, SVG, also known as high-voltage dynamic reactive compensation generator, or static synchronous compensator, refers to a device that uses a free-commutation power semiconductor bridge converter to perform dynamic reactive compensation. SVG is currently the best solution in the field of reactive power control. Compared with traditional phase-shifting machines, capacitor reactors, and traditional SVC represented by thyristor-controlled reactors TCR, SVG has incomparable advantages. SVG ventilation equipment is used when cooling SVG.

[0003] For example, patent application number CN202110388233.3 discloses a new type of SVG ventilation equipment, which is designed to solve the problems of inconvenient fixing and excessive space occupation of existing SVG ventilation equipment during use.

At the same time, the filter is not easy to handle and is prone to blockage and bacterial growth. If it is disassembled, the ventilation of the SVG is affected. Therefore, professionals in this field provide a new type of SVG ventilation equipment to solve the above-mentioned problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figures 1 to 4 In the utility model, a novel SVG ventilation device includes a cabinet 1 and an SVG device 2 installed therein. A detachable ventilation box 3 is provided on the left side of the cabinet 1. The interior of the ventilation box 3 is connected to the interior of the cabinet 1. A partition 4 is fixedly connected to the left wall of the ventilation box 3. The right end of the partition 4 passes through the ventilation box 3 and extends to the interior of the cabinet 1. An exhaust pipe 5 is fixedly connected to the left side of the ventilation box 3. The exhaust pipe 5 is located on the top of the partition 4 and is connected to the interior of the ventilation box 3. An air intake pipe 6 is fixedly connected to the left side of the ventilation box 3. The air intake pipe 6 is located at the bottom of the partition 4 and is connected to the interior of the ventilation box 3. The interior of the ventilation box 3 is connected, and a fan 7 is installed on the inner wall of the air inlet pipe 6. A mounting seat 8 is fixedly connected to the inner bottom wall of the ventilation box 3, and the top of the mounting seat 8 is in contact with the partition 4. A driving motor 9 is fixedly installed on the front of the ventilation box 3. The output shaft of the driving motor 9 passes through the ventilation box 3 and extends to the inside of the mounting seat 8. Through grooves 10 are provided on the left and right sides of the mounting seat 8. Two sealing plates 11 and two mounting plates 12 are fixedly connected to the output shaft of the driving motor 9. The two mounting plates 12 are respectively located at the top and bottom of the two sealing plates 11, and a filter element 13 is installed on the mounting plate 12.

[0023] A one-way valve 14 is installed at the top of the exhaust pipe 5, and the one-way valve 14 is connected to the inside of the intake pipe 6;

[0024] A filter screen 15 is installed at the bottom of the air inlet pipe 6 , and the fan 7 is located on the top of the filter screen 15 .

[0025] The two sealing plates 11 and the two mounting plates 12 are in contact with the inner wall of the mounting seat 8 and are slidably connected;

[0026] A collecting box 17 is installed at the bottom of the ventilation box 3 , and the collecting box 17 is located at the bottom of the mounting seat 8 .

[0027] The cabinet 1 is installed in the installation area, the SVG device 2 is operating inside the cabinet 1, the ventilation box 3 is connected to the left side of the cabinet 1 and is connected to the inside of the cabinet 1. When the SVG device 2 is in operation, the fan 7 is powered on and operates, and the fan 7 generates suction to draw the airflow at the bottom of the air inlet pipe 6 into the inside of the air inlet pipe 6. Under the obstruction of the filter 15, large-sized debris in the airflow can be blocked to prevent it from entering the ventilation box 3 or the inside of the cabinet 1 and affecting the normal operation of the SVG device 2. Then the airflow is guided by the air inlet pipe 6 and passes through the through groove 10 to enter the inside of the mounting seat 8. The airflow blocked by the sealing plate 11 needs to penetrate the filter 13 in the mounting plate 12. The filter 13 is composed of an activated carbon plate and a microporous filter plate. After the airflow penetrates, it is discharged from the mounting seat 8 through the through groove 10 on the right, and the airflow is purified and restricted by the partition 4 to enter the machine Inside the cabinet 1, as the airflow continues to enter, the airflow begins to move upward, thereby accelerating the circulation speed of the air inside the cabinet 1 and taking away the heat generated by the SVG device 2. The airflow flows back to the inside of the ventilation box 3 through the top of the partition 4 and is discharged through the exhaust pipe 5. The one-way valve 14 can prevent untreated airflow from entering the inside of the cabinet 1, and the airflow containing heat will move upward after being discharged and will no longer enter through the air intake pipe 6. In actual use, if the filter element 13 at the top has been used for a long time, the driving motor 9 drives the two sets of mounting plates 12 and the sealing plate 11 to rotate synchronously, so that the top and bottom mounting plates 12 exchange positions, and the sealing plate 11 still seals the inside of the mounting seat 8. Then the user can disassemble the collection box 17 to process the filter element 13, and this process will not affect normal ventilation.

[0028] In the utility model, ventilation of the interior of the cabinet 1 is achieved by arranging a ventilation box 3 on the left side of the cabinet 1 carrying the SVG device 2, and a partition 4 is arranged inside the ventilation box 3 so that an airflow loop is formed inside the cabinet 1 to accelerate the circulation speed of the airflow, and can quickly carry the heat generated by the SVG device 2 to achieve a heat dissipation effect. At the same time, by arranging multiple groups of filter elements 13 and matching the filter screen 15, filtering of the circulating airflow can be achieved, and the filter element 13 driven by the drive motor 9 can be flipped, thereby facilitating the cleaning of the filter element 13 without affecting the ventilation effect of the SVG device 2.

[0029] See also Figure 1, wherein: a movable door 16 is hinged on the front of the cabinet 1, a handle is connected to the movable door 16, and the movable door 16 and the cabinet 1 are sealed.

[0030] In the present invention, during the installation and operation of the cabinet 1 and the SVG device 2, the user can open the movable door 16 to inspect and install the cabinet 1 and the SVG device 2. At the same time, the handle can provide a fulcrum, and the sealed movable door 16 will not affect the ventilation effect.

[0031] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
