[0024] A control device for output harmonic current of an APF active filter compensation system includes an output harmonic current control body 1. The output harmonic current control body 1 includes a housing 101, a display screen 102 and control buttons 103. A support frame 2 is fixedly connected to the outer wall of the housing 101. A transparent cover plate 4 and a translation component for adjusting the horizontal position of the transparent cover plate 4 are integrated on the outer side of the support frame 2. A connecting seat 6 is fixedly connected to the inner wall of the transparent cover plate 4, and a handle 7 is provided on the outer side of the connecting seat 6.

[0025] After operating the control button 103, pull the transparent cover plate with the handle 7. The sliding sleeve 5 slides along the fixed rod 3 until the transparent cover plate 4 completely covers the front of the display screen 102 and the control button 103. Rotate the positioning rod 8 to make it engage with the sliding sleeve 5. The transparent cover plate 4 is positioned by the contact friction between the positioning rod 8 and the outer wall of the fixed rod 3. This can prevent the control button 103 from being accidentally touched. As the transparent cover plate 4 passes through the display screen 102, it can provide longitudinal pushing force to the handle 7. The spring 14 is compressed and the sliding rod 12 slides along the connecting seat 6 until the handle 7 abuts against the connecting seat 6. At this time, the base plate 13 pushes the cleaning block 11 to contact the glass cover plate 4 on the outside of the display screen 102. Pull the handle 7 horizontally, and the cleaning block 11 will clean the outside of the glass cover plate 4.

[0026] Specifically, such as Figure 2 and Figure 4As shown, the support frame 2 has a mounting strip fixedly connected to its outer wall, and the mounting strip is fixedly connected to the outer wall of the housing 101 via the fixing rod 3. The U-shaped fixing rod 3 has mounting strips fixedly connected to its outer side, and the mounting strips are fixed to the outer wall of the housing 101 via the fixing rod 3. This ensures the stability of the working position of the transparent cover 4 and improves the convenience of the overall assembly and disassembly of the transparent cover 4, thereby improving the ease of use of the control device for output harmonic current.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the translation component includes a sliding sleeve 5 fixedly connected to the rear end face of the transparent cover plate 4. A positioning rod 8 is screwed onto the outer wall of the sliding sleeve 5, and the open end of the positioning rod 8 abuts against the outer wall of the support frame 2. The sliding sleeve 5 slides along the fixed rod 3 until the transparent cover plate 4 completely covers the front side of the display screen 102 and the control button 103. The positioning rod 8 is rotated to screw onto the sliding sleeve 5. The positioning of the transparent cover plate 4 is achieved through the contact friction between the positioning rod 8 and the outer wall of the fixed rod 3. A side piece 9 is fixedly connected to the outer wall of the connecting seat 6, and the side piece 9 is fixedly connected to the transparent cover plate 4 through a locking rod 10, ensuring the ease of disassembly and assembly of the connecting seat 6. The rear end face of the handle 7 is fixedly connected to the connecting... A sliding rod 12 is slidably connected to the inner wall of the connector 6. The open end of the sliding rod 12 is fixedly connected to a base plate 13, and a cleaning block 11 is fixedly connected to the rear end face of the base plate 13. A spring 14 is fixedly connected between the rear end face of the handle 7 and the inner wall of the connector 6, providing longitudinal pushing force to the handle 7. When the spring 14 is compressed, the sliding rod 12 slides along the connector 6 until the handle 7 abuts against the connector 6. At this time, the base plate 13 pushes the cleaning block 11 to contact the glass cover plate 4 on the outside of the display screen 102. When the handle 7 is pulled horizontally, the cleaning block 11 will clean the outside of the glass cover plate 4. The base plate 13 and the cleaning block 11 are fixedly connected by adhesive, ensuring the ease of disassembly and assembly of the cleaning block 11.

[0028] Working principle: After operating the control button 103, the transparent cover is pulled by the grip 7, and the sliding sleeve 5 slides along the fixed rod 3 until the transparent cover 4 completely covers the front of the display screen 102 and the control button 103. The positioning rod 8 is then rotated to engage with the sliding sleeve 5. The transparent cover 4 is positioned by the contact friction between the positioning rod 8 and the outer wall of the fixed rod 3, thus preventing accidental activation of the control button 103. Furthermore, as the transparent cover 4 passes the display screen 102, it provides a longitudinal pushing force to the grip 7, compressing the spring 14 and causing the sliding rod 12 to slide along... Slide the connecting seat 6 until the handle 7 abuts against the connecting seat 6. At this time, the base plate 13 pushes the cleaning block 11 to contact the glass cover plate 4 on the outside of the display screen 102. When the handle 7 is pulled horizontally, the cleaning block 11 will clean the outside of the glass cover plate 4. The U-shaped fixing rod 3 is fixedly connected to the outer side of the mounting strip, and the mounting strip is fixed to the outer wall of the housing 101 through the fixing rod 3. This ensures the stability of the working position of the transparent cover plate 4 and improves the convenience of the overall disassembly and assembly of the transparent cover plate 4, thereby improving the ease of use of the control device for output harmonic current.
