具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
如图1至3所示，根据本发明的实施例，防爆垫包括垫体10，垫体10包括第一通孔11、第一开口12和锁合结构，第一通孔11贯穿垫体10，并供穿柜母线30穿过垫体10；第一开口12由垫体10的外周向内延伸至与第一通孔11连通；锁合结构设置在垫体10上并位于第一开口12的两侧，将第一开口12锁合。通过第一开口12可以方便地将垫体10套设到穿柜母线30上，因而可以方便地在未安装防爆垫的开关柜内添加防爆垫，而且无需拆除整个穿柜母线30，节省了时间提高了效率。锁合结构能够保证工作过程中第一开口12处于锁合状态，进而保证垫体10稳固地套设在穿柜母线30上，而避免垫体10从穿柜母线30上脱落。
锁合结构包括凹槽21和凸起22，凹槽21位于第一开口12的第一侧；凸起22位于第一开口12的第二侧，与凹槽21配合，凸起22的形状与凹槽21的形状相适应。凹槽21和凸起22的配合方式装配简单且安全性高，能够有效地保证工作可靠性。
在本实施例中，凹槽21包括平行于第一开口12的第一竖段和连接在第一竖段与第一开口12之间的第一横段，该第一横段垂直于第一开口12。凸起22包括与凹槽的第一横段相适应的第二横段221和与凹槽21的第一竖段相适应的第二竖段222。这种配合方式能够有效地保证垫体10整体的结构强度。凹槽21和凸起22的结构也可以是其它形状，只需保证工作过程中，第一开口12处于锁合状态即可，例如凹槽21为三角形，沿远离第一开口12的方向凹 槽21的截面积逐渐增大，相应地，凸起22为与该凹槽21形状相适应的三角形。
优选地，防爆垫包括至少两个的垫体10，至少两个垫体10的第一开口12错开设置，这样能够保证防爆垫整体的结构强度，在受外力作用下防爆垫整体的受力均匀。
更优选地，防爆垫包括两个的垫体10，两个垫体10的第一开口12间隔180度。
垫体10为阻燃且耐电压的橡胶材料。为了避免穿柜母线30产生电弧时造成意外事故，垫体10的材料为阻燃耐电压的且具有防爆性的材料，为了方便地将防爆垫装配到穿柜母线30上，垫体10为具有弹性的橡胶材料，同时橡胶材料也能够有效地填充穿柜母线30与穿柜套管之间的缝隙，实现最好的防爆效果。
根据本发明的实施例的另一方面，开关柜包括多个相互分隔的母线室、穿柜母线30和穿柜套管，穿柜母线30穿设在多个母线室内，穿柜套管套设在穿柜母线30外，还包括防爆垫，防爆垫为上述的防爆垫，防爆垫套设在穿柜母线30上，穿柜套管套设在防爆垫外。穿柜母线30上套设有多个防爆垫，开关柜内的多个母线室之间通过分隔板分隔，穿柜母线30的与每个分隔板的位置相对应的位置上至少设置有一个防爆垫。通过在穿柜母线30上设置防爆垫，将穿柜母线30分隔为多段，保证当任一段的穿柜母线30发生电弧时，防爆垫能够有效阻挡，避免电弧影响到其它段的穿柜母线30，有效地保证了开关柜的安全。
防爆垫的尺寸和外形可以有多种，使用时选用适合穿柜套管的尺寸和外形的防爆垫。安装过程中，松开锁合结构的凹槽21和凸起22，将第一开口12掰开，将防爆垫的两个垫体10分别套设到穿柜母线30上，多个防爆垫对应各个母线室将穿柜母线30分割为多段。这样可以不用完全拆下穿柜母线30就可完成安装防爆垫，减小停电时间；同时可以提升开关柜安全性能；此种防爆垫尤其适用于KYN-28型开关柜；发生单个母线室故障时有效避免故障向两侧延伸而造成的事故损失的扩大；防爆垫的投资小，实际可操作性强。
优选地，防爆垫的可以有多种形状，只需与需要的穿柜套管的内周的形状适应即可
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：第一开口能够方便地将防爆垫套设到穿柜母线上，而无需拆卸穿柜母线，节省了时间，同时能够保证穿柜母线的安全。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
