Description

Technical Field

[0002] A harmonic compensation device is a device used in power systems. Its main function is to compensate and control the harmonics generated in the system. In power systems, harmonics refer to fluctuations whose frequencies are integer multiples of the fundamental frequency, which can affect the stability of the system and the operation of the equipment.

[0003] When installing a harmonic compensation device, the harmonic compensation device is often only fixed at the position where it needs to be installed by bolts, and there is no structure for cooperating with vibration reduction. During the use of the harmonic compensation device, it is easy to cause vibration due to environmental influences, mechanical vibrations or human influences. Since the harmonic compensation device does not have a vibration reduction structure, strong vibrations may cause the internal components of the harmonic filter to loosen or fall off, thereby affecting its normal filtering effect and performance. Frequent vibrations may cause fatigue damage to the internal components of the harmonic filter, accelerate equipment aging, and reduce the life of the equipment. In addition, the heat dissipation effect is not good enough. The problem with the above technology is that the harmonic compensation device does not have a vibration reduction component to cooperate with it, and vibration reduction cannot be performed when vibration occurs in the harmonic compensation device.
