Description

Technical Field

[0001] This utility model belongs to the technical field of hybrid APF devices, and more specifically, it relates to a wall-mounted hybrid APF device. Background Technology

[0002] A Hybrid Active Power Filter (APF) is a power quality management device that combines the advantages of active power filter (APF) and passive power filter (PF) technologies. It is used to dynamically suppress harmonics in the power system, compensate reactive power, and improve voltage quality.

[0003] Based on the above, the inventors have discovered the following problems: When installing existing hybrid APF devices, most of them are directly fixed with bolts when they need to be suspended on the wall for use. The height is relatively fixed. When the height needs to be adjusted in subsequent operations, the staff needs to use external tools to re-drill holes and reconnect the bolts. This not only affects the aesthetics of the wall, but also causes inconvenience to the staff, and indirectly reduces the connection efficiency between the hybrid APF device and external components, which is quite inconvenient.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a wall-mounted hybrid APF device in order to achieve a more practical value. Utility Model Content

[0011] Further, the two sides of the L-shaped connecting plate are provided with threaded holes two, and one end of the bolt is connected to the threaded hole two through the threaded hole one.

[0012] Compared with the prior art, the utility model has the advantages of:

[0013] Through the cooperation between the rotating rod, the bevel gear one and the bevel gear two, when the device body needs to be adjusted in height for subsequent use or connection, the rotating rod can drive the bevel gear two, the bevel gear one and the threaded rod to rotate, so that the L-shaped sliding block can be moved in height, thereby the height of the device body can be adjusted according to the needs of the staff, the connection efficiency of the device body and external elements is indirectly improved, the staff is not inconvenient due to the fixed height, and the staff does not need to frequently open holes in the wall for installing the device body in height, and the practicability is greatly improved.
