本发明涉及电气设备技术领域，特别涉及一种集成开关设备。
在海上风电设备中，风机塔筒内部空间小，要求开关设备结构节凑、占地面积小、重量轻。
传统的开关设备通过绝缘隔板实现各元件之间的连接，三相断路器、隔离开关、接地开关、快速接地开关元件分别位于单独的壳体内，互相之间通过通气或不通气的绝缘隔板连接。
同时，集成开关设备中三相开关组件的三相动侧导体结构各不相同，在进行组装时，需要首先辨别各个动侧导体，然后再将各个动侧导体安装在预设位置，如果安装位置出错，还需要拆卸后重新安装，导致集成开关设备的组装效率较低。
因此，如何提高集成开关设备的组装效率，是本领域技术人员亟待解决的技术问题。

如图1和图2所示，隔离开关包括隔离开关静侧导体41、41'、隔离开关动侧导体42、42'、隔离开关出轴43、43'、隔离开关绝缘支撑44、44'。

如图9所示，灭弧室相间距L1，隔离开关、隔离接地开关相间距L2，L2＜L1，壳体支筒的直径小于壳体主筒11的直径。将隔离接地开关隔离静侧导体31和隔离开关静侧导体44、41'的边相导体向相间方向偏转，在满足绝缘要求的前提下，隔离开关、隔离接地开关的边相静侧导体向相间方向偏转，使得隔离开关、隔离接地开关相间距小于灭弧室相间距，进而使得壳体支筒直径小于主筒直径，减小隔离开关、隔离接地开关相间距，进而减小开关设备宽度和高度以及重量，降低加工难度。
快速接地开关包括：快速接地开关动侧导体51、51'；快速接地开关绝缘支撑52、52'；快速接地开关出轴53、53'。

快速接地开关、外壳、盖板及快速接地开关驱动机构集成为接地可拆卸模
块。在具体使用时，三相主回路导体61'穿过快速接地开关所处壳体15内侧，各相中心线与壳体15轴线平行。根据主接线需要，可将快速接地开关可拆卸模块与隔离开关替换为隔离接地开关。快速接地开关与其操动机构、壳体组成可拆卸模块，可根据应用场景，灵活拆卸或替换为隔离接地开关。
具体的，快速接地开关作为可拆卸模块一部分，可灵活布置，实现两回出线、三回出线、四回出线、每一回出线全部配隔离接地开关、部分出线配隔离接地开关部分出线配隔离开关+快速接地开关等不同主接线方式的结构布置，进行出线扩展时将断口数量进行扩展，每回出线均对应相应的隔离断口，避免了电气主接线中三回及以上出线共用一个隔离断口的情况。
隔离开关静侧导体41、41'的自由端向灭弧室动侧导体21方向延伸。隔离开关动侧导体42、42'以及隔离接地开关动侧导体32通过均分别绝缘件串接后固定在壳体支筒内部的金属或非金属的凸起19上。通过将隔离开关静侧导体41向灭弧室动侧导体21方向延伸，并通过绝缘支撑固定在主筒内部的金属或非金属凸起上，增加一个支筒、隔离开关以及快速接地开关形成的可拆卸模块，可将三回出线开关设备扩展为四回出线开关设备，每一回出线均对应单独的隔离断口，避免了两回线路共用隔离断口的情况。即将隔离开关静侧导体41延长，通过一个绝缘件固定到壳体上，绝缘件类同于隔离开关动侧导体用到的绝缘件，把三相的隔离开关静侧导体41串起来
具体的，如图8所示，隔离接地开关动侧导体32通过绝缘件固定在壳体圆柱形支筒内部的金属或非金属的凸起19上，具体的，三个隔离接地开关动侧导体32通过同一个绝缘件安装，具体的，隔离接地开关动侧导体32套设在绝缘件上。动侧导体绝缘件的两处凸起19与壳体支筒通过焊接或螺栓连接，
且关于真空灭弧室22中间相的中心线b与隔离接地开关动侧导体32中间相的中心线b'形成的平面成镜像对称布置。
隔离接地开关的接地开关静侧35、出线套管62与电缆舱64均集成在盖板上，盖板与外壳可拆卸连接，盖板上位于述外壳外侧的表面设有接地块171，接地开关静侧35通过硬质导体172短接后与所述接地块171连接，接地块171和硬质导体172位于电缆舱64外部。
隔离接地开关动侧导体32中间相的中心线b'与壳体支筒中心线b”平行但不重合。隔离接地开关出轴33位于壳体支筒内，与固定在壳体支筒外的隔离接地开关操动机构72直接连接，隔离接地开关操动机构72通过隔离接地开关出轴33转动带动隔离接地开关动侧导体32内部导体在沿其中心线移动，实现“隔离合闸、接地分闸”、“隔离分闸、接地分闸”、“隔离分闸、接地合闸”三种工况切换。隔离开关动侧导体42、42'同样通过绝缘件固定在支筒13内侧的两个金属或非金属的凸起上，与隔离接地开关动侧导体32固定方式同理。隔离开关出轴43、43'位于支筒14内，与固定在支筒14外侧的隔离开关操动机构74直接连接，隔离开关操动机构74通过隔离开关出轴43、43'转动带动隔离开关动侧导体42、42'内部导体沿其中心线移动，实现隔离开关分闸、合闸状态切换。
上述结构为风机塔筒中占比最多的三回出线对应的开关设备，两组隔离开关和快速接地开关模块分别布置在真空灭弧室22两侧。如图4所示，对于四回出线的开关设备，在壳体主筒11上增加一个壳体支筒，用于安装隔离开关和快速接地开关(或隔离接地开关)模块，将隔离开关静侧导体41、41'向灭弧室动侧导体21方向延伸，通过绝缘件将延伸出的三相导体固定在壳体主筒
11内金属或非金属的凸起19上，扩展为四回出线开关设备。如图5所示，对于两回出线开关设备，取消一个快速接地开关和隔离开关(或隔离接地开关)模块，对应的壳体支筒可采用盖板封堵或取消。
集成式开关设备通过将三相断路器、隔离开关、隔离接地开关集成到同一壳体内部，将操纵机构、电缆仓集成在壳体外部，整体布置结构紧凑，体积小，适合于塔筒内部应用和检修。
本发明将隔离开关、隔离接地开关静侧集成到断路静侧导体和动侧导体上，各元件之间不需要通过绝缘隔板进行连接，节省结构尺寸、减轻产品重量。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
