In recent years, the rapid development of the economy and the acceleration of power grid construction have led to the widespread use of transformers in various types of buildings. With limited land resources, public facilities like power distribution rooms are often constructed in the basements of high-rise residential buildings. This has brought attention to the issue of transformer noise control. Despite the relatively low noise levels produced by transformers, they can still impact human health and create potential safety risks. Transformer noise pollution is quietly affecting residential areas, commercial centers, businesses, hospitals, schools, and other locations. So, how can we address this problem?
Transformer noise is influenced by both internal and external factors. Hanks Soundproofing focuses on ensuring equipment safety while primarily addressing external factors to reduce noise.
Key influencing factors include:
1. Vibration generated by components such as the transformer casing and fans.
2. Instability in equipment installation, amplifying vibration noise during operation.
3. Noise issues arising from theä¸åˆç†scale and structure of underground power distribution rooms.
Characteristics of Transformer Noise:
The low-frequency noise emitted by transformers has strong penetration capabilities and slow attenuation. It can propagate over distances exceeding 30 meters, primarily impacting the indoor acoustic environment within buildings, particularly floors 1-5. This type of noise can be irritating, potentially leading to headaches, tinnitus, and other symptoms over time.
Methods for Transformer Noise Control:
Through scientific analysis, Hanks Soundproofing aims to meet the national standard of 35 dB for "Noise Emission Limits for Structure-Borne and Impact Noise in Buildings" in Class 1 areas at night. To achieve this, we propose the following measures:
1. Replace the ordinary doors and windows of the power distribution room with soundproof windows and doors.
2. Install vibration-damping mounts at each corner of the transformer base to reduce the transmission of vibrations through the floor.
3. Add a flexible copper bar at the connection point between the busbar and the transformer.
In addition to these measures, further improvements can be made to enhance noise reduction effectiveness. For example, using sound-absorbing materials on walls and ceilings can further minimize noise interference. Regular maintenance of transformers and their components can also prevent excessive vibration and noise generation. By combining these approaches, we can significantly mitigate transformer noise pollution, creating quieter and healthier environments for residents and workers alike.
