A GTO Cascade Equipment of Saving Energy for Variable Speed Control System
-
摘要: 節能型GTO串級調速裝置是一種新型的整流裝置。該裝置的功率因數得到很大的改善,它的推廣應用將對節能有較重要的意義。
論文討論了改善功率因數的原理和方法,試驗測定了繞線型電機。一般串級調速裝置和節能型GTO串級調速裝置的功率因數特性曲線。曲線對比能夠說明節能型GTO串級調速裝置高功率因數的優點。Abstract: A GTO cascade equipment of saving energy is a modem tyPe of rec-tifire equipment.The Power factor of this equipment is improved greatly. The application of this system will have more important significance for economy of energy. In this Paper the principles and methods of improv-ing the power factor are discussed. Performance curves of the power fac for of a wound-rotor induction motor, a SCR cascade and a GTO cascade equipment are shown also. These Curves are drown from a experime-ntal equipment developed, by us. The comparison between these curves can be used to explain the advantage of the high power factor of a GTO cascade equipment.-
