Proposed pull dynamic control process concept and to study different excitation voltage

The intelligent AC contactor pull-depth process of real (test) experimental studies and theoretical analysis, the pull process dynamics control concepts and research at different excitation voltages, different closing phase angle, a different  mcb circuit breaker  scheme case contactor dynamic characteristics. In a large number of dynamic characteristics test basis, explore the optimal control scheme, to  electric transformer  reduce the pull process and elimination of contact bounce impact core purpose. Intelligent AC contactor zero current breaking research, and to achieve a  air circuit breaker  circuit breaking control of micro-arc energy. Based on the large number of tests to study the impact on the current through zero-off control of the main factors, thereby increasing the current through zero off control reliability.
