| Abstract: | In view of Electrical life of contactor due to contact erosion caused by secondary back-chatting in closing of contactors,the paper states necessity and feasibility of developing new smart AC/DC controlled AC-contactors.The paper suggests developing a general chip-controlled circuit adaptable for contractors by use of attractive force curve produced by instantaneous force control so that an integrated system that can use AC power and DC power as well as measurement.Hence,smart,undersized AC contactor can be achieved,electrical life of contactors can be prolonged,use of copper and iron can be greatly reduced,energy can be reserved and noise can be lowed;besides,structure optimization of iron core and magnetic circuit can reduce product cost. |
