概述Product Structure

ZW32M-12型户外高压真空断路器为额定电压12kV,三相交流50Hz的户外配电设备，它主要用来开断、关合电力系统中的负荷电流、过载电流、

短路电流。适用于变电站及工矿企业配电系统中作保护和控制作用，及农村电网频繁操作的场所。

本断路器具有体积小、重量轻、防凝露、免维护等特点，能适应较恶劣的气候条件和污秽环境。

该型号产品采用永磁操作机构进行操作；由于永磁操作机构由永磁体提供动作能量，使开关快速保持在分合闸位置，其机械零件数量少、机械传动链短，从而大大提高了开关的可靠性和机械寿命。

ZW32M-12 type outdoor high voltage vacuum circuit breaker is rated voltage 12kV,three-phase AC 50Hz outdoor distribution equipment,which is mainly used for breaking,closing power system load current,overload current,short-circuit current.For substation and industrial andmining enterprises distribution system for the protection and control of the role and place of rural power grids frequent operation.

The circuit breaker has small size,light weight,anti-condensation,maintenance-free characteristics,can adapt to poor weather conditionsand dirty environments.

The models with permanent magnet operating mechanism operates;since the permanent action energy operating mechanism provided bya permanent magnet,the switch quickly to keep the points off position,a small number of mechanical parts,mechanical transmission chain isshort,thus greatly improving the switch reliability and mechanical life.
