Anti-vibration system
When electric transformers with dielectric oil or coated dry are in operation, they emit a characteristic noise resulting from the vibrations of the magnetic sheets (mageto constriction) which they contain. This vibration comes from the 50 Hz alternating current that runs through them, characterizing a fundamental vibration frequency of 100 Hz and several corresponding vibration harmonics.
In order to dampen its vibrations, we suggest using shock absorbers from the SanerVib® range between the support supports of the transformers (feet, beams, wheels, etc.) and the ground. These are several low-frequency silent blocks specially developed to provide high anti-vibration performance at transformer excitation frequencies, depending on their weight and the desired attenuation.
The SanerVib® must be chosen precisely so that the internal damping elements are neither too much nor too little compressed, thus fulfilling thei function to the full. SanerVib® are available in 2 vibration absorption levels (up to 80% and up to 99%).
They can be configured according to 3 types of use :
- SanerVib for wheels : for transformers with wheels,
- SanerVib-SG : to equip a transformer without wheel,
- SanerVib-VibeR or SanerVib-SL : to equip a "rolling" transformer.
TECHNIKELEC® also offers anti-vibration plates (PAV) are made of nitrile rubber to reduce the propagation of noise caused by transformer vibrations. They absorb 40% to 60% of vibrations and are placed under the industrial machines to avoid its displacement.
