作为一种可替换的实施方式，第一部分16除了图示中的形状以外，还可以是棱柱、圆柱或其他形状形成的凸起，只要保证绕线区域14和中心绝缘筒3之间具有间隔即可。
仍如图2所示，本实施例中的凸台13朝向远离中心的方向具有第二部分17，第二部分17凸出对接后的第一半壳11和第二半壳12的环形外壁设置，在第一半壳11和第二半壳12的第二部分17上设有同轴的固定孔，并在两同轴的固定孔中插设有导电销轴18，该导电销轴18用于实现线圈和倍压板21的电连接。设置导电销轴18可以用来固定对接扣合后的第一半壳11和第二半壳12，可以避免设置额外固定件固定环形结构，另外，线圈的进线端和出线端通过导电销轴18传递出磁芯骨架1，有利于将其电连接至倍压板21上，避免了在线圈和倍压板21之间使用长导线进行连接时导线连接点电场控制困难、操作复杂的问题，有利于磁芯骨架1的最小化设计。
如图1和图2所示，本实施例中的凸台13上还设置有沿轴向方向向外延伸的抵接块19，抵接块19用于与侧面的倍压板21抵接，抵接块19相对凸台13沿轴向上凸出一定高度，在多个磁芯骨架1相互装配时，该抵接块19可以抵接在相邻的倍压板21上，从而使磁芯骨架1和倍压板21之间具有一定的过油间隙，有利于散热油在二者之间流动，从而带走变压器热量并起到绝缘作用，在此，该抵接块19的高度应根据实际需要绝缘距离设计，绝缘需求距离越大，该抵接块19的高度越高。
实施例2
本实施例提供了一种倍压组件2，包括如实施例1中所述的磁芯骨架1，并在磁芯骨架1的腔体内设置有磁芯，绕线区域14上缠绕有线圈。
在此，倍压组件中采用如上所述的磁芯骨架，可保证倍压组件2良好的绝 缘强度，在注油时散热油通过通孔15进入至环形结构中，又可使散热油包裹磁芯，从而使倍压组件具有良好的散热效果。
需要说明的是，本实施例中，绕设后的线圈两端分别距离凸台13的边缘设有2mm宽度的间隔，有利于保证散热油从通孔15顺利进入到线圈和磁芯之间，进而使注油后的磁芯和第一半壳11、第二半壳12之间的空气顺利排出，避免内部由于存在气泡而出现局部放电导致变压器油品下降的隐患。
如图2所示，本实施例的倍压组件2还包括与磁芯骨架1配合固定的倍压板21，具体地，倍压板21设置在磁芯骨架1的一侧，磁芯骨架1上插接有分别用于连接线圈的进线端和出线端的导电销轴18，导电销轴18和倍压板21通过插接电连接。作为一种可替换的实施方式，该导电销轴18和倍压板21之间可以通过锡焊固定。此外，该导电销轴18可以是黄铜镀镍、铁芯为铁磁材料，从而避免受磁芯影响正常导电效果。
在此，倍压板21可采用现有成熟的pcb倍压板21，倍压板21上设置有用于输出串联后电流的输出端子212，以及用于导通进入串联后的线圈的进线端子211。在各线圈分别伸出的导电销轴18插接于倍压板21后，在倍压板21内部进行串接连接，串接连接设置有利于通过多个线圈电压叠加形成输出高压，且响应速度较快；此外，通过控制线圈匝数、绕线区域14实际绕设线圈数量等因素又可调整实际倍压组件2的输出电压，从而使倍压组件2使用灵活，且适配性好。
实施例3
本实施例提供了一种变压器，包括多组依次串联的如实施例2中所述的倍压组件2。
本实施例中，通过依次串联多组倍压组件组成变压器，可以将变压器中最高输出电压分布于各倍压组件2上，从而可以在较低的绝缘强度下满足各倍压组件2的绝缘需求，便于结构化设计和生产工艺的实现，减小变压器结构尺寸；
此外，由于各个倍压组件2之间串接连接，各倍压组件2内具有多个串联 的线圈组件，可以实现快速建立高压，响应速度较快；另外，各倍压组件2生产后统一进行装配，可便于批量生产，避免不同批次生产的倍压组件2之间存在差异而影响工作效果，有利于实现性能均一化设计和生产。
具体地，如图2和图3所示，倍压组件2上连接有倍压板21，多组倍压组件2的倍压板21依次平行插接于电连接板22上，位于电连接板22上的一组倍压组件2的倍压板21进线端子211与相邻倍压板21的输出端子212连接，从而通过电连接板22实现多组倍压组件2的串联。倍压板21的侧面均设置有第一卡槽213，多个倍压组件2的第一卡槽213共同卡接于电连接板22上，从而起到对倍压组件2的固定效果。需要说明的是，电连接板22可采用现有成熟的pcb板件。作为一种可替换的实施方式，也可不设置电连接板22，而将各倍压板21通过导线连接。
如图3至图5所示，变压器包括穿设各倍压组件2的中心绝缘筒3，中心绝缘筒3内设有用于配合各倍压组件2的初级绕组线圈，中心绝缘筒3的两端分别卡接有骨架限位板31，各倍压组件2被堆叠约束在两骨架限位板31之间。作为一种可替换的实施方式，骨架限位板31与中心绝缘筒3卡接后通过尼龙螺钉固定连接。
在此，在两骨架限位板31之间固定连接有安装板23，安装板23沿中心绝缘筒3的轴向延伸，倍压板21的顶端设置有第二卡槽214，多个倍压组件2上的第二卡槽214共同卡接于安装板23上，从而进一步对倍压组件2径向约束固定。作为一种可替换的实施方式，安装板23和骨架限位板31之间、电连接板22和骨架限位板31之间均可采用尼龙螺钉固定连接。
实施例4
本实施例提供了一种X射线高压发生器，包括如实施例3中所述的变压器，由于其采用了实施例3中所述的变压器，因此具有变压器所有的优点。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其 它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本申请的保护范围之中。
