对于中型电机的噪声治理,常规处理的方法是安装整体隔声罩。在周围空间十分狭小不允许安装整体隔声罩的情况下,只能用安装进气、排气消声器和局部隔声罩的办法来降低其噪声,这里介绍的200kW交直流变流机组的降噪方法就属于后一种情况。 一、200kW变流机组性能参数 200kW变流机组为可逆式交直流变流机组,由直流电机、交流电机和励磁机组成(如图1所示)。其主要性能参数为:
For medium-sized motor noise management, the usual approach is to install the overall noise enclosure. In a very small surrounding space does not allow the installation of the overall sound insulation cover, can only be installed with air intake, exhaust muffler and local noise cover approach to reduce its noise, here introduced 200kW AC and DC converter noise reduction The method belongs to the latter case. A, 200kW converter unit performance parameters 200kW inverter unit for the reversible AC-DC converter unit, the DC motor, AC motor and exciter components (as shown in Figure 1). Its main performance parameters are:
