本文介绍了在空分设备停运检修之际,为提高电网功率因素,把配空压机的TD-148/89-4型三相交流同步电动机改为调相机,从而变“罚”为“奖”。文章指出:在同步电机改为调相机时,必须确定电机的容量与考虑电机的温升及其电气回路。文章对小型同步电动机改为调相机的可能性也作了叙述。文章最后认为:对目前闲置的电动机-发电机组(M-G机组)的同步电机,只要略为改革一下也可作调相机使用。图1。
This article describes the air separation plant outage overhaul, in order to improve the grid power factor, with air compressor TD-148 / 89-4-phase three-phase AC synchronous motor to adjust the camera, so as to “fine” to “ prize”. The article pointed out: When the synchronous motor is changed to adjust the camera, must determine the capacity of the motor and consider the motor temperature rise and its electrical circuit. The article also describes the possibility of changing a small synchronous motor to a camera. The article concludes that: for the current idle motor - generator (M-G unit) of the synchronous motor, as long as a little reform can also be used for adjusting the camera. figure 1.
