【摘要】 目前国内大多数工频炉无功补偿仍停留在人工手动操作水平上,有的炉子调压范围宽,功率因数等测量仪表误差大,不能提供准确的控制依据,我们研制了一套以IBM-Pc机为核心的工频炉功率因数自动补偿及电气参数测量系统.该系统测量准确,可靠性高,定时更新指示工频炉各电气参数和打印表,功率因数控制在0.95～0.99之间,节能效果显著。更多还原

【Abstract】 At present, the power factor self-compensation of most of frequency stoves in our country is still operated by hand. The adjusted voltage range of some stoves is wide. The power factor measuring system do not work well and could not provide exact basis for control. Authors develop a set of power factor self-compensation of frequency stove and electric parameter measuring system on the basis of IBM-PC computer. The system has accurate measuring and high reliability, and can renew every electric parame- ters of frequency stove and duplicate tables on time. The power factor can be controlled at range of 0. 95～0.99. The system has the outstanding effect on energy conservation.更多还原
