ZW32-40.5 vacuum(recloser)consist of electric spring mechanism (or permanent magnent)and reliable intelligent controller.It mainly used in medium-voltage overhead line grid for breaking and closing load current,overload current and short-circuit current.It has the abability of automatically reclosing brake 0-3times
Main Features
1.High reliabilty 2.Maintance during mechanism life 3.High mechanism life and electric life. 4.Mechine valume is small ,weight is light and easy to install 5.Standard relay current protection and quick automaticlly reclose brake
Structure
1.ZW32-40.5 mainly consist of intergret solid-seal pole,current transformer,electrical mechanism and box.The model is designed in small shape.At same time equip with manual breakingan closing brake device.Current is transformer is choosed by the requirement of custom.
2.Intelligent control unit provide with the ability of long-distance controling through communication port,operated by remote controller(cable,optical fiber,GPRS/CDMA,GCM.etc are selected for communication passage)
3.Intelligent control unit intalled adjacent to breaker.Through control cable to connect with breaker.Electric source of intelligent control include main electric source and backup source.Main electric is AC or DC 220V,is acquired by high voltage line through PT.Backup source is supplied by storage battery(installed in intelligent control unit box).When proper functioning,main electric source supply electric to backup source(fully charged) is able to bear machine to work for not less 48 hours
4.There are urgent breaking brake handgrip set in breaker operation mechanism for urgent breaking operation when control system or electric source happen.
