AI Technical Summary
The noise accumulation inside the prefabricated substation compartment is severe, affecting normal operation and the environment, and existing technologies are unable to effectively reduce the noise.
The design employs a double-layered chamber structure and sound-absorbing panel components to optimize airflow organization, alter the noise wave transmission path, and reduce noise propagation through reflection and refraction by the sound-absorbing panels.
It effectively reduces the impact of cabin noise on the outside world, improves the stability of the equipment's working environment, and extends the equipment's service life.
