以下结合实施例对本申请的特征和性能作详细描述。
本申请实施例中隔离接地开关的一个实施例如图1所示，包括筒体10，筒体10的整体结构与现有技术完全相同，筒体10上设置有接地静端安装孔、传动机构安装孔和隔离接地动端安装孔，其中接地静端安装孔位于筒体10的左端，接地静端安装孔中安装有隔离接地开关的接地静触头20。隔离接地动端安装孔位于筒体10的底部靠左位置，隔离接地动端安装孔上安装有第一盆式绝缘子(图中未标出)，第一盆式绝缘子的中间部分设有导电块，导电块上固定安装有动端部件(图中未示出)，动端部件包括动触座，动触座内导电安装有可沿左右方向导向移动的隔离接地动触头，当隔离接地动触头向左移动时，与接地静触头插接导电。传动机构安装孔位于筒体10的顶部靠左位置，传动机构安装孔上安装有传动装配(图中未示出)，传动装配的一端与隔离接地动触头传动相连、另一端与隔离接地操动机构30传动相连，以带动隔离接地动触头沿左右方向往复移动。
本申请实施例的隔离接地开关与现有技术的不同主要有三个方面，第 一，筒体10的右端固定有第二盆式绝缘子70，结合图2所示，第二盆式绝缘子70的中间部分设有导电块701，而现有技术中筒体的右端固定的是封板。
第二，筒体10的顶部靠右位置设置有快速接地动端安装孔(也即现有技术中的隔离静端安装孔)，在本申请实施例中，快速接地动端安装孔上安装有安装板40，安装板40上安装有快速接地开关的快速接地动触头50，隔离接地开关还包括与快速接地动触头50传动相连的快速接地操动机构60，以驱动快速接地动触头50上下动作。
第三，第二盆式绝缘子70上固定有静端组件80，如图2所示，静端组件80包括静端支撑81和安装在静端支撑81上的屏蔽罩82、隔离静主触头83、隔离静弧触头84、快速接地静主触头85以及快速接地静弧触头86。其中，隔离静主触头83和隔离静弧触头84构成隔离接地开关的隔离静触头，隔离接地动触头位于接地静触头20和隔离静触头之间，当隔离接地动触头向右移动时，与隔离静触头插接导电。
快速接地静主触头85和快速接地静弧触头86构成快速接地开关的快速接地静触头，因此静端支撑81上设置有用于安装隔离静触头的第一安装结构和用于安装快速接地静触头的第二安装结构。并且，由于静端支撑81通过第二盆式绝缘子70固定连接在筒体10的右端，因此静端支撑81上还设置有用于与第二盆式绝缘子70固定连接的固定结构。
具体的，静端支撑81包括圆柱状本体811，圆柱状本体811的轴线沿左右方向延伸。上述第一安装结构设置在圆柱状本体811的左端、上述固定结构设置在圆柱状本体811的右端、上述第二安装结构设置在圆柱状本体811的外周面上且位于上侧。
在一个实施方案中，结合图2、图3、图4以及图6所示，圆柱状本体811的左端设置有凹槽816，上述第一安装结构包括设置在凹槽816槽壁上 的环槽8163以及设置在凹槽816槽底的槽底平面8161，凹槽816以及环槽8163的槽口均朝左设置。由于隔离静弧触头84位于内侧，因此也可称之为内侧弧触头；同时由于隔离静主触头83位于外侧，因此可称之为外侧主触头。隔离静弧触头84和隔离静主触头83同轴设置，隔离静主触头83为片状触指结构，沿圆周方向均匀分布在环槽8163内；隔离静弧触头84通过第二螺栓872固定在槽底平面8161上，槽底平面8161上设置有第二螺栓穿孔8162。
屏蔽罩82用于对隔离静主触头83和隔离静弧触头84进行屏蔽，屏蔽罩82为类似“碗状”中空薄壁结构，其左右两端均为敞口，左端敞口处设置有第一内翻沿821、右端敞口处设置有第二内翻沿822，第一内翻沿821抵触在隔离静主触头83的端部，用于隔离静主触头83的水平限位。屏蔽罩82上沿圆周方向间隔设置有多个凹部824，第三螺栓873穿过凹部824与圆柱状本体811螺纹连接，实现屏蔽罩82固定在静端支撑81上，圆柱状本体811的左侧端面上设置有第三螺栓安装孔8164。
上述第二安装结构为凸设在圆柱状本体811的外周面上的圆台812，圆台812的轴线沿上下方向延伸。快速接地静主触头85的中心设置有槽口朝上的插接槽，第四螺栓874穿过插接槽的槽底与圆台812螺纹连接，圆台812上设置有多个第四螺栓安装孔8121，实现快速接地静主触头85固定在静端支撑81上。快速接地静弧触头86和快速接地静主触头85同轴设置，快速接地静弧触头86设置在快速接地静主触头85的内部，且快速接地静弧触头86的下端穿过插接槽的槽底与圆台812螺纹连接，实现快速接地静弧触头86固定在静端支撑81上。圆台812上设置有与静弧触头86配合的触头安装孔8122，触头安装孔8122位于圆台812的中心。
屏蔽罩82上设置有用于露出快速接地静弧触头86和快速接地静主触头85的露出孔823，并且快速接地静主触头85穿过露出孔823且在穿出的 端部上设置有球面，穿出设置可以方便与快速接地动触头50的导电接触，球面设置可以避免尖端放电现象。快速接地静触头与快速接地动触头50导电接触时，快速接地静弧触头86插入快速接地动触头50内部与其内壁接触，快速接地动触头50插入快速接地静主触头85的插接槽内，与插接槽的槽壁接触。
圆柱状本体811的内部为中空结构，使得圆柱状本体811的右端形成端板814，上述固定结构为设置在圆柱状本体811右端的用于与第二盆式绝缘子70贴合固定的固定平面，该固定平面也即端板814的侧面。具体的，如图5所示，端板814上凸设有凸台8142，凸台8142的表面构成固定平面。如图2所示，静端支撑通过贯穿端板814的第一螺栓871与盆式绝缘子70上的导电块701固定连接，因此在端板814上设置有第一螺栓穿孔8141，如图4～图6所示。
如图2所示，第一螺栓871和第二螺栓872的头部均位于中空结构内，因此中空结构形成用于旋拧操作第一螺栓871和第二螺栓872的操作空间815，圆柱状本体811的侧面上设置有供旋拧工具伸入操作空间815内的伸入口813，如图3～图6所示。
屏蔽罩82将整个静端支撑81围设在内，包括伸入口813，所以屏蔽罩82在静端支撑81和第二盆式绝缘子70固定连接以后再固定在静端支撑81上。
隔离接地开关在装配时，先将隔离静主触头83和隔离静弧触头84安装在静端支撑81上，然后将静端支撑81上固定在第二盆式绝缘子70上，然后安装屏蔽罩82，然后通过露出孔823安装快速接地静弧触头86和快速接地静主触头85，最后将组装好的整体部件安装在筒体10的右端。
使用时，线路正常工作状态下，隔离接地开关的隔离开关(DS)处于合闸状态，此时普通接地开关(ES)和快速接地开关均处于分闸状态，电 流经第二盆式绝缘子70的导电块701流入静端支撑81、隔离静主触头83、隔离接地动触头，实现隔离接地开关与线路的导通。当线路出现故障需要快速接地时，快速接地开关处于合闸状态，电流经第二盆式绝缘子70的导电块701流入静端支撑81、快速接地静触头、快速接地动触头50，并通过隔离接地开关的筒体将电流通过接地极引入大地，实现线路及设备的快速电气隔离。
本申请实施例中的隔离接地开关，快速接地静触头属于静端组件的一部分，实现了将快速接地静触头布置在筒体内，且快速接地静触头安装在静端支撑81上，实现了与隔离静触头的集成，利用的是用于安装隔离静触头的静端支撑，不需要另外设置固定结构，不但方便了快速接地静触头的布置，而且可以简化结构设置。同时，屏蔽罩82上开设有用于露出快速接地静触头的露出孔823，这样一方面不影响快速接地静触头与快速接地动触头50之间的导电接触，实现快速接地操作，另一方面屏蔽罩82可以对快速接地静触头起到屏蔽作用，无需再另外设置屏蔽件，因此可以简化结构设置。
本申请实施例中的隔离接地开关没有改变原有的筒体结构，也没有增大原有的筒体体积，实现了将快速接地动触头安装在筒体上，不仅方便的将快速接地开关和隔离接地开关集成在一起，实现两者的共气室设计，同时也实现了小型化设计的目的，大大简化了结构设置，最大程度的节省了成本。
另外，隔离静触头设置在静端支撑的端部，快速接地静触头设置在静端支撑的周向，两者垂直布置，设计合理，充分利用了筒体内现有的空间，可以减小静端支撑在水平方向上的长度，进而减小静端组件乃至整体结构的体积，节约成本。
在隔离接地开关的其他实施例中，快速接地静主触头可以不穿过露出 孔，此时无需设置球面结构。
在隔离接地开关的其他实施例中，快速接地静主触头和快速接地静弧触头也可以是现有技术中常见的其他结构形式。
在隔离接地开关的其他实施例中，快速接地静触头可以只包括快速接地静主触头，没有弧触头。
在隔离接地开关的其他实施例中，可以在屏蔽罩上设置一个操作孔，以供人手伸入内部，此时可以先将屏蔽罩固定在静端支撑上，再将静端支撑固定在盆式绝缘子上。
在隔离接地开关的其他实施例中，当静端支撑和屏蔽罩的大小关系满足屏蔽罩不能将静端支撑完全围设在内时，可以将圆柱状本体右端的端板设置在屏蔽罩的外部，此时也不需要注意组装顺序问题。
在隔离接地开关的其他实施例中，隔离静主触头也可以是其他形式的触头，例如和快速接地静主触头相同，此时无需设置环槽，第一安装结构只设置一个安装平面即可，当然此时也可以不设置凹槽，圆柱状本体的左端为实心柱体结构。
在隔离接地开关的其他实施例中，圆柱状本体整体为实心柱体结构，此时圆柱状本体的右端面形成固定平面，此时可以利用螺栓穿过盆式绝缘子的导电块与圆柱状本体的右端螺纹连接，实现静端支撑固定在盆式绝缘子上，此时圆柱状本体的右端面上设置有螺纹孔。
在隔离接地开关的其他实施例中，整个筒体的结构可以左右对称一下，也即静端支撑固定在筒体的左端，此时第一安装结构设置在圆柱状本体的右端，固定结构设置在圆柱状本体的左端，接地静触头固定在筒体的右端。
在隔离接地开关的其他实施例中，第一安装结构和第二安装结构可以分别设置在圆柱状本体的左右两端，此时将固定结构设置在圆柱状本体的外周面上，当然此时快速接地动触头以及快速接地操动机构的设置位置也 需要相应改变。
在隔离接地开关的其他实施例中，静端支撑不包括圆柱状本体，静端支撑可以是方块状，或者是角形杆状。
在隔离接地开关的其他实施例中，快速接地静触头也可以和接地静触头集成在一起，此时静端支撑上原本安装的是接地静触头，此时屏蔽罩原本用于对接地静触头进行屏蔽。
本申请中静端组件的实施例为：静端组件的具体结构与上述隔离接地开关实施例中的静端组件相同，在此不再重述。
以上所述，仅为本申请的较佳实施例，并不用以限制本申请，本申请的专利保护范围以权利要求书为准，凡是运用本申请的说明书及附图内容所作的等同结构变化，同理均应包含在本申请的保护范围内。
本申请实施例实现了快速接地静触头与隔离静触头或接地静触头的集成，利用的是安装隔离静触头或接地静触头的静端支撑，不需要另外设置固定结构，方便了快速接地静触头的布置。露出孔的设置不影响快速接地静触头与快速接地动触头之间的导电接触，使屏蔽罩可以对快速接地静触头起到屏蔽作用，无需再另外设置屏蔽件，因此可以简化结构设置。
