背景技术
灭弧室是万能式断路器不可缺少的部分，灭弧室的作用是消除分断时产生的电弧，灭弧室消灭电弧的能力强弱直接影响了断路器的分断性能。现有万能式断路器灭弧室，包括隔弧壁，灭弧栅片和引弧片，这种灭弧室结构通过灭弧片和引弧片在电弧产生时将电弧引入灭弧室内消除电弧。隔弧壁将电弧隔离在灭弧室以内，防止电弧飞出，造成安全隐患。
现有灭弧室的隔弧壁无法适用于不同宽度的灭弧室。对于母线宽度不同的万能式断路器，灭弧室的宽度也相应不同，导致隔弧壁不能通用。在不同母线宽度的断路器隔弧壁种类繁多，不易管理，且产品开发周期长，成本高，因此有必要加以改进。

如图3所示，延长板3包括第一延长板31和第二延长板32，第一延长板31和第二延长板32位于两个隔弧壁2的隔板22之间两端，并与隔板22连接。延长板3也可以是两块独立的第一延长板31和第二延长板32，第一延长板31和第二延长板32分别对两个隔弧壁2的隔板22之间两端进行连接固定。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
