AB-3S-12 series circuit breaker is a new generation of column mounted intelligent vacuum circuit breakers developed by our company, which integrates advanced domestic and foreign technologies, draws on the strengths of many families, adopts a new design concept, and utilizes high-tech means and new research and development
概述Product Structure
3S-12系列户外真空永磁断路器是本公司综合国内外先进技术、博采众家之长、采用全新设计理念、运用高科技手段、 新研制的新一代柱上真空断路器。该产品既可作为35kV变电所主变10kV出线的开关，也可作为配电网的柱上开关，和本公司生产的控制器相结合便可方便实现控制、保护、测量、通讯
主要特点：采用永磁机构，使用部件大量减少，合闸功率大幅度减小，稳定可靠，无需定期维护保养；采用进口户外环氧树脂作为外绝缘材料重量轻、寿命长达15年以上，耐候性好，无油、无SF6,符合环保要求；动作时间短，能快速切断故障，保护配合方便灵活；选用外置PT作为电源无须外接电源即可实现电动操作；选用专用遥控器可实现遥控操作，无须上杆即可进行停送电操作；选用一体化设计的高压隔离开关，使结构紧凑安装检修非常方便。
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.
