CRW2智能型万能式断路器 结构特征
本断路器分固定式和抽屉式两种结构;?断路器为立体布置,由侧板、横梁组成框架,每相触头系统安装在框架上,上面装灭弧室。操作机构在断路器右前方,通过主轴与触头系统相连。电动操作机构通过方轴与机构连成一体装于断路器下部,作为断路器的储能或直接闭合之用,储能后闭合由释能电磁铁完成。在左侧板上方装有防回跳机构,以防止断路器在分断时弹跳。欠电压和分励脱扣器经过放大机构与脱扣半轴相连,以减少断路器的脱扣力。面板上有显示断路器工作位置的指示牌"I""O"及智能控制器,手动操作手柄供手动储能使用(仅指2000壳架)。
抽屉式断路器由断路器本体与抽屉座组成,通过断路器本体上的母线与抽屉座上桥型触头的插座接通主回路,具有机械联锁装置,能保证断路器在断开状态下进行主回路转换。
控制器由互感器组件、电子部件及执行元件等三部分组成,互感器组件由空心互感器和速饱和互感器组成,直接套在母线上,二次引出线与控制器相连。
