NFC-T rapid switching switch

1) the design for 0.4Kv electric capacity rapid compensation . 2)be used in impact strength load local 3)it has more protect

 Product Introduction

The rapid capacitor switching switch of NFC-T series was designed for dynamic and fast compensation of the power capacitor .

The rapid capacitor switching switch of NFC-T series mainly applied to the impact load , it need to quickly switching the electrical load site of the capacitor , such as : welding machine , steel rolling , port suspended , elevator , inverter frequency furnace and other load change site .

This capacitor switch has the high following speed , and can be effective compensation the impact load , the response time is 10~20miliseconds , effective saving the energy , it is the irreplaceable product of AC contactor and combination switch .

The capacitor switch module is using high-speed CPU , pulse transformer triggering , it has multiple protection schemes and 20ms fast switching technology , to ensure the trigger module controlled thyristor is voltage zero-crossing connected , current  zero-crossing broken , and do not produce switching surge .

NOTE : In order to ensure the rapid switching switch could safety operation , you should series the reactor of 5%-7% in the each of capacitor switch .
