下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。
如图1至图4所示，本实施例中公开了一种隔离开关熔断器组件，其包括至少一个隔离开关熔断器1，隔离开关熔断器1包括可拆卸连接的隔离开关11和熔断器组件12，熔断器组件12包括熔断器121和用于容纳熔断器121的保护盒122，保护盒122上设置有用以对熔断器121进行散热的散热通道，且保护盒122上还设置有能观察熔断器121状态的透明视窗1222。
首先，相较于断路器而言，熔断器121能对相对应的回路进行快速截断 以提高电路的安全性；其次，当一回路出现短路故障时，通过与熔断器组件12可拆卸连接的隔离开关11控制该回路的断开以便直接更换熔断器组件12，在保证更换熔断器组件12的安全性的同时避免影响其它回路的正常运行，且通过保护盒122上的散热通道对熔断器121进行散热以尽可能延长熔断器121的使用寿命；最后还能通过透明视窗1222及时观察到熔断器121状态以判断是否需要更换熔断器121，也能实现塑壳短路器的可视化。该隔离开关熔断器组件能保证在更换某一回路的熔断器121时不会影响其它回路的正常运行，且由于隔离开关11与熔断器组件12的可拆卸连接，能便于更换熔断器组件12，并通过透明视窗1222实现对熔断器121的可视化以及时观察熔断器121状态。
示例性地，透明视窗1222设置在保护盒122的顶端。
其中，考虑有更换熔断器121的需求，保护盒122由两个半保护罩拼接形成，以避免更换整个熔断器组件12，降低维护成本。
本实施例中，保护盒122两相对侧壁上分别均开设有通风口1221以形成散热通道，即熔断器121处于两个通风口之间，进而保证熔断器121的散热效果。
考虑到回路是三相交流电回路，结合图3所示，一个熔断器组件12内设置有三个熔断器121，三个熔断器121沿保护盒122的长度方向间隔排列在保护盒122内，以分别对应A、B和C相。
其中，保护盒122的两相对侧壁上以每个熔断器121为中心均周设有多个通风口1221以形成多个散热通道，从而保证保护盒122内的每个熔断器121的散热效果。
同理，保护盒122的顶端上开设有三个沿保护盒122的长度方向间隔排列的透明视窗1222，透明视窗1222与熔断器121一一对应且位于相对应的熔断器121的正上方，以便从三个熔断器121中准确判断出现故障的熔断器121。
具体地，如图3所示，隔离开关熔断器1还包括连接铜排组件13，连接铜排组件13包括连接铜排131，连接铜排131分别与隔离开关11的输入端子和熔断器121的输出端子通过螺栓实现可拆卸地连接。当然，在其它实施例中，也可采用其它的结构实现隔离开关11与熔断器121的可拆卸连接，本实施例不做具体限制。
可以理解的是，隔离开关11的输出端子数量与保护盒122内的熔断器121数量相同。
进一步地，结合图4所示，连接铜排组件13还包括能分别与隔离开关11的底端和保护盒122的顶端抵接的第一保护罩132，第一保护罩132包括可拆卸连接的第一罩体1321和第一盖体1322，第一罩体1321内设有能容纳连接铜排131的第一容纳槽；第一盖体1322能与第一罩体1321卡接并封堵住第一容纳槽，实现从隔离开关11的输入端子到熔断器121的输出端子的绝缘防护，提高隔离开关熔断器1的使用安全性。
具体地，第一罩体1321设置有两个分别位于第一容纳槽两侧的第一导向槽13211，第一罩体1321和第一盖体1322其中的一个上设置有第一限位孔13221，另一个上设置有能与第一限位孔13221配合的第一卡扣13212，第一盖体1322能在第一导向槽13211内滑动直至第一卡扣13212与第一限位孔13221卡合以使第一盖体1322与第一罩体1321卡接。同理，当需要使第一 盖体1322脱离第一罩体1321时，只需反方向滑动第一盖体1322使第一卡扣13212脱离第一限位孔13221即可。
示例性地，为了保证卡接的稳定性，第一限位孔13221和相对应的第一卡扣13212设置有多个。
本实施例中，隔离开关熔断器1还包括接线铜排组件14，接线铜排组件14包括接线铜排141，接线铜排141分别与熔断器121的输入端子和外部线缆可拆卸地连接。当然，在其它实施例中，也可采用其它的结构实现熔断器121与外部线缆的可拆卸连接，本实施例不做具体限制。
结合图6所示，接线铜排组件14还包括能与保护盒122的底端抵接的第二保护罩142，第二保护罩142包括可拆卸连接的第二罩体1421和第二盖体1422，第二罩体1421内设有能容纳接线铜排141的第二容纳槽；第二盖体1422能与第二罩体1421卡接并封堵住第二容纳槽，实现从熔断器121的输入端子到外部线缆的输出端子的绝缘防护，提高隔离开关熔断器1的使用安全性。
具体地，第二罩体1421设置有两个分别位于第二容纳槽两侧的第二导向槽14211，第二罩体1421和第二盖体1422其中的一个上设置有第二限位孔14221，另一个上设置有能与第二限位孔14221配合的第二卡扣14212，第二盖体1422能在第二导向槽14211内滑动直至第二卡扣14212与第二限位孔14221卡合以使第二盖体1422与第二罩体1421卡接。同理，当需要使第二盖体1422脱离第二罩体1421时，只需反方向滑动第二盖体1422使第二卡扣14212脱离第二限位孔14221即可。
示例性地，为了保证卡接的稳定性，第二限位孔14221和相对应的第二 卡扣14212设置有多个。
其中，结合图7所示，为了方便检修人员能通过透明视窗1222观察到熔断器121状态(即熔断器121的熔丝是否熔断)，熔断器组件12还包括与熔断器121连接的故障指示器123，熔断器121与故障指示器123一一对应，通过故障指示器123能判断熔断器121状态。
具体地，所示故障指示器123为弹片，弹片的一端设置在熔断器121顶端，另一端与熔丝连接，当熔丝未熔断时，如图7所示，弹片处于第一状态，即弹片完全贴合在熔断器121的顶端上；当熔丝因回路短路而熔断时，如图8所示，弹片处于第二状态，弹片与熔丝连接的一端因熔丝熔断而失去了紧固力导致其远离熔断器121，即弹片的一端相较于熔断器121的顶端翘起，从而能使检修人员很直观地判断熔断器121状态。
本实施例中，为了能分别控制多个回路的状态，隔离开关熔断器组件包括多个隔离开关熔断器1，多个隔离开关熔断器1沿保护盒122的宽度方向间隔排列，从而避免相邻两个保护盒122上的散热通道相互干涉，尽可能保证对每个熔断器121的散热效果。
其中，隔离开关熔断器组件还包括绝缘隔板2，绝缘隔板2与每个第二保护罩142底端均抵接，用以将与外接线缆的输出端连接部与隔离开关熔断器1其它部分分隔开，尽可能提高安全性。
使用时，每一回流的电流从外部线缆输入依次经过对应的接线铜排141、熔断器121、连接铜排131、隔离开关11，并在汇流排上实现汇流。当某一回路发生短路故障时，对应那一路的熔断器121会熔断以保护电路安全，且熔断器121上的故障指示器123会弹出以提示故障所在处。当维修人员进行 维护时，通过保护盒122上的透明视窗1222判断出现故障的熔断器121的具体位置，并通过旋转该回路对应的隔离开关11的把手以切断该回路和汇流排的连接，并通过分别滑动第一盖体1322和第二盖体1422以能快速拆卸第一保护罩132和第二保护罩142，从而拧松螺栓以将熔断器组件12整体取出进行后续的更换即可。
以上内容仅为本发明的较佳实施例，对于本领域的普通技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，本说明书内容不应理解为对本发明的限制。
