Product Structure
AB-3S-12 series of permanent magnet outdoor vacuum circuit breaker is the Company's consolidated foreign advanced technology,publicgambling house long,with a new design concept,the use of high-tech means,the latest development of a new generation of column vacuumcircuit breakers.The product can be used as the main transformer 10kV Substation 35kV switch outlet,but also as a distribution network of columnswitch,and this combined with the company's controller can facilitate the realization of control,protection,measurement,communication,is toachieve preferred equipment distribution network automation and miniaturization substation.
Main features:Magnetic actuation (permanent magnet)institutions so that a significant reduction in parts,greatly reducing the switch on thepower,stable and reliable,no regular maintenance;imported outdoor epoxy resin as outer insulation material,light weight,long life more than15 years,the weather is good,no oil,no SF6,comply with environmental requirements;action time is short,fast cutting fault protection with theconvenience and flexibility;use solar or CT as a power,no external power supply electric operation can be realized;use special remote controlenables remote operation without lever stop transmission operation can be carried out;the selection of high-voltage isolation switch integrateddesign,compact structure,convenient installation and maintenance.
