Technical Field

[0001] The utility model relates to the technical field of harmonic elimination devices, in particular to a harmonic elimination device wiring structure. 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] In the operation of the existing harmonic eliminator, one end of the cable connected to the external harmonic treatment equipment to be eliminated is electrically connected to the terminal through a conductive gasket by cooperating with the terminal electrically connected to the terminal end of the harmonic eliminator, and then the contact position of the two is abutted by a nut threaded on the terminal to achieve the connection operation between the harmonic eliminator and the external harmonic treatment equipment to be eliminated. However, the terminal on the existing harmonic eliminator is usually directly exposed and protruding at the end of the harmonic eliminator, which easily makes the connection between the conductive gasket at one end of the cable and the terminal exposed to the outside, and then it is easy to be disturbed by the external working environment in subsequent operations, affecting the operation stability of the harmonic eliminator. At the same time, during the installation of the harmonic eliminator, it is easy to cause the installation position of other equipment in the power system to be blocked, and it is easy to cause the terminal and the conductive gasket to be damaged by impact, further affecting the reliability of the harmonic eliminator operation.
