对任何矿井来讲,主要通风机装置都是用电大户,所以许多研究设计人员都在探求降低矿井通风用电的办法,当然不是以牺牲井下工作人员生命为代价的办法,可以通过仪器仪表或者通过掉接电器旋转频率达到风机特性和矿井通风系统的和谐一致。在调节同步电机的旋转频率上考虑了用变频器的驱动,变频器可以是高压,或者是带2个同步变压器的低压部,后来又转向了使用电脑的操控系
For any mine, the major ventilator units are large electricity consumers, so many research designers are looking for ways to reduce mine ventilation and electricity, certainly not at the expense of subsurface staff, through instrumentation or By turning off the frequency of electrical rotation of fans to achieve the harmony and mine ventilation system. In adjusting the rotation frequency of the synchronous motor, considering the drive with the inverter, the inverter can be a high voltage, or a low voltage part with two synchronous transformers, and later turned to a control system using a computer
