变压器在运行时，在室内产生大量的热量，为了控制室温，保证变压器正常运转，需要采用强制机械通风措施，但通风机工作时发出较大噪声，影响周围环境，本文通过在风机上设置一种消声装置，在不减小风机通风量的同时消除风机的空气动力性噪声。

while the transformers are operating in substation, a massive source of heat wil be created in the room. In order to control the indoor temperature and ensure the normal operation of transformers, compulsory measures of mechanical ventilation need to be adopted. However, the working ventilators create large noise, which can impact the circumstance. This paper demonstrates a method of eliminating the aerodynamic noise of a ventilator, but not reducing its ventilation quantity, by means of instal ing a muffler device on the ventilator.
