近几年乡镇企业发展很快,其中电气技术的应用日益重要。针对目前乡镇企业在用电方面的实际需要,结合一些工程建设的经验,在此谈几点实用电气技术问题,希望能对推进乡镇企业的技术进步,保证安全生产有所助益。 1.风机的起动风机在各类农副产品加工厂中使用很多,和一般机械动力设备的起动性质不同,风机的起动有自己的特点,主要是起动惯量大,起动时间长,大风机的起动对电网影响比较明显等。五、六十年代国产的风机多为仿苏型,设计裕量较大,其起动方式依电机功率大小不同,选用全压或降压起
In recent years, township and village enterprises have developed rapidly, of which the application of electrical technology is increasingly important. In view of the current actual needs of township and village enterprises in terms of electricity consumption, combined with some experience in construction, in this talk about several practical electrical technology problems, hoping to promote the technological progress of township enterprises to ensure that safety in production is helpful. 1. Blower fan Blower used in a variety of agricultural products processing plant, and the general nature of the starting mechanical power equipment is different from the start of the fan has its own characteristics, mainly starting inertia, starting a long time, start the blower The impact of the grid is obvious. In the fifties and sixties the domestically produced fans were mostly imitation Su-type, the design margin is large, the starting method depends on the power of the motor, the choice of full pressure or reduced pressure
