Description

Technical Field

[0001] The utility model relates to the technical field of harmonic elimination devices, in particular to an assembly structure of a harmonic elimination device. Background Art

[0002] A detuner is a device used to suppress harmonic interference in circuits. In power systems, electrical equipment such as motors and transformers will generate harmonics when they are working. Such harmonics will interfere with or even damage other equipment or systems. The function of a detuner is to reduce or eliminate such harmonics through certain circuit design and component installation to ensure the normal operation of the power system.

[0003] When the existing harmonic eliminator is in operation, it usually needs to be assembled on the external power equipment for use. A base for assembly is provided on the mounting end of the harmonic eliminator, and the base is threadedly connected and installed with the mounting hole on the external equipment through a screw rod to fix the working position of the harmonic eliminator. However, the base on the mounting end of the existing harmonic eliminator is usually fixed. After the harmonic eliminator is assembled, the working position of the harmonic eliminator is fixed. However, when the installation position of the harmonic eliminator is blocked by other equipment or needs to be adjusted according to the cable connection position, it is inconvenient to adjust the subsequent placement position of the harmonic eliminator within a certain range, resulting in a lack of applicability in the assembly operation of the harmonic eliminator. Utility Model Content

[0004] In view of the above technical problems existing in the application of the existing harmonic elimination device, the utility model provides a harmonic elimination device assembly structure.

[0005] A harmonic elimination assembly structure, comprising a harmonic elimination body, wherein two sides of the bottom of the harmonic elimination body are rotatably connected with adjustment plates, one end of the adjustment plate is threadedly connected with a bolt, one end of the bolt is rotatably connected with a base plate, one end of the base plate is threadedly connected with a screw, and the screw is threadedly connected with a preset mounting hole on an external device;

[0006] A limiting assembly for respectively fixing the adjustment plate and the base plate is arranged on one end of the bolt.

[0007] Furthermore, support rods are respectively arranged on both sides of the bottom of the detuning device body, and one end of the support rod is rotatably connected to one end of the adjustment plate.

[0008] Furthermore, a nut is threadedly connected to one end of the support rod, and the nut is movably abutted against the adjustment plate.

[0009] Furthermore, the limiting assembly includes a positioning nut and a fixing nut, the positioning nut is threadedly connected to the middle section of the bolt, and the positioning nut is located between the opposite surfaces of the adjustment plate and the base plate, and movably abuts against the adjustment plate.
