In　order　to　solve　the　problem　of　low　efficiency　of　traditional　intelligent　contactor　performance　test,　this　paper　proposes　a　contactor　dynamic　characteristic　test　and　analysis　system　based　on　NI　CompactRIO,　which　is　convenient　for　measuring　the　performance　index　of　intelligent　contactor.　The　system　includes　a　Human-Machine-Interaction(HMI)　interface,　which　can　control　the　action　of　the　contactor　to　be　detected　and　collect　signals　in　the　host　computer　platform.　According　to　the　trend　of　the　collected　signal　waveform,　the　performance　indexes　of　the　contactor,　such　as　the　closing/opening　time,　the　closing/holding　power,　are　calculated.　The　system　also　has　the　functions　of　cyclic　switching　test　and　automatic　data　storage,　which　greatly　improves　the　automation　level　and　efficiency　of　the　test.　It　provides　data　support　for　the　improvement　and　optimization　of　the　control　strategy　of　intelligent　contactor.　©　Beijing　Paike　Culture　Commu.　Co.,　Ltd.　2024.
