| Abstract: | Adopt OrCAD/PSpice emulate software,the paper has carried on detailed analysis and studied to three phase voltage and current waves for AC contactor in closing and breaking course.The paper has put forward the brand-new no-arc control method and designed an intelligent no-arc AC contactor based on the magnetic latching relay.The contactor is reasonable price,simple and convenient to use.The performance index is fine.The new contactor employs three magnetic latching relays,and the control is agility.The contact of each phase connected with only one unidirectional silicon controlled component in parallel.Realize no-arc closing and breaking.Every performance index of the contactor has been increased. |
