煤炭工业对电能有很强的依赖性,且是耗电大户,尤其是风机、水泵类负荷的耗电量,占生产电耗的比例很大。利用变频凋速技术对风机、水泵类负荷进行节能改造,是解决煤炭工业高耗电的有效措施。按照国家节能降耗的要求,对风机电控进行了变频调速和自动化改造。1 改造前风机参数及运行情况
The coal industry has a strong dependence on electric energy, and it is a large power consumer, especially the power consumption of fans and pumps, which accounts for a large proportion of the power consumption in production. It is an effective measure to solve the high power consumption of the coal industry by using the frequency conversion and speed-up technology to save energy for fans and pumps. In accordance with the requirements of national energy-saving, frequency control and automatic transformation of the fan electronic control. 1 before the transformation of fan parameters and operating conditions
