Noise reduction measures in transformer room

September-30th-2025

Sound insulation material:

  1. Sound-absorbing panels: Using high-density sound-absorbing panels on walls and ceilings can effectively absorb sound waves and reduce noise reflection.
  2. Sound insulation cotton: Filling the building structure with sound insulation cotton can effectively block the spread of sound, especially between walls and ceilings.
  3. Acoustic glass: If the transformer room has windows, using double or triple glazing can significantly reduce the intrusion of external noise.

Sealed design:

  1. Door and window sealing: Use high-quality sealing strips to ensure that the doors and windows of the transformer room are completely sealed when closed to prevent air and sound leakage.
  2. Wall gap treatment: Seal the wall joints and the places where pipes pass through to prevent sound from transmitting through the gaps.

Vibration Control:

  1. Anti-vibration pads: Installing anti-vibration pads under transformers and equipment can absorb vibrations generated during equipment operation and reduce noise.
  2. Elastic brackets: Use elastic brackets to fix equipment and reduce the transmission of vibrations into the building structure, thereby reducing noise.

Air circulation design:

  1. Ventilation system: Design a reasonable ventilation system, avoid using high-noise fans, and choose low-noise fans and air conditioners to reduce the noise generated when the equipment is running.
  2. Muffler: Installing a muffler in the ventilation duct can effectively reduce the air noise generated when the fan is running.

Noise Barrier:

  1. Soundproof wall: Building a soundproof wall outside the transformer room using high-density materials such as concrete, masonry, etc. can effectively prevent noise from spreading outward.
  2. Green belt: Planting trees and shrubs around the transformer room can form a natural noise barrier and absorb some sound waves.

Regular maintenance:

  1. Equipment maintenance: Regularly inspect and maintain transformers and ancillary equipment (such as switches, distribution equipment, etc.) to ensure that the equipment operates in optimal conditions and reduce noise caused by equipment aging or wear.
  2. Lubrication and maintenance: Lubricate moving parts regularly to reduce friction noise and extend equipment life.

Reasonable layout:

  1. Equipment placement: Arrange equipment reasonably inside the transformer room and place noisy equipment (such as transformers and fans) away from work areas or crowd activity areas to reduce the impact on personnel.
  2. Avoid resonance: Ensure there is sufficient distance between devices to avoid mutual interference and resonance, thereby reducing noise generation.

Acoustic Design:

  1. Interior shape design: When designing the transformer room, consider the interior shape and the acoustic properties of the materials, and choose appropriate wall and ceiling shapes to reduce the gathering and reflection of sound waves.
  2. Acoustic simulation: Perform acoustic simulation during the design phase to predict noise propagation and optimize design solutions.

Summarize

By combining these measures, the noise level in the transformer room can be significantly reduced, creating a more comfortable and safe environment. This not only helps protect the quality of life for surrounding residents, but also improves worker efficiency and reduces the incidence of occupational diseases. Reasonable noise reduction measures should be adjusted and optimized according to specific circumstances to achieve optimal results.
