| Abstract: | Referring to the existed intelligent control projects at home and abroad,and based on the current regularity presented in the operating process,the controlling policy depengding on the relationship between the changing rate of the current and the length of the air-gap was brought out.The target of adjusting current can be achieved through changing the PWM duty ratio continuously inresponse to the sampled current and voltage data.With the data from the corresponding experiment,the following conclusion can be drawn: compared with the traditional AC contactor,the viberating time and the energy comsumtion of the one optimized with the intelligent unit are reduced meanwhile the mechanical performance and reliability are enchanced. |
| Keywords: | AC contactor segmented voltage intelligent control sample of voltage and current |
