Description

一种横式一体绝缘真空断路器 技术领域
本发明属于轨道交通真空断路器领域，特别涉及一种横式一体绝缘真空断路器。
背景技术
真空断路器用于车辆主电路的接通和开断，也可用于主电路的保护，是车辆牵引系统的一部分。
目前，用于干线机车和动车组的真空断路器为引进技术，其包括低压控制部分、底板组装、弹簧支架组装、操纵杆、真空开关管组装和绝缘子，其中低压控制部分装于底板组装底部，低压控制部分通过弹簧支架组装、操纵杆与真空开关管组装传动相连，以控制真空开关管的通断。
现有的真空断路器具有以下缺点：
第一，绝缘子采用由水平绝缘子和垂直绝缘子相配合的分体式绝缘结构，即水平绝缘子承担极间绝缘，垂直绝缘子承担对地绝缘。由于垂直绝缘子垂直安装于底板组装上，若真空断路器安装在户外，则在恶劣气候条件下，雨雪等容易在垂直绝缘子伞裙上发生堆积，从而在垂直绝缘子上形成对地的导电路径，导致发生绝缘事故。为了解决该问题，既有产品只能增加垂直绝缘子高度，但这会增加真空断路器的重量和体积，给车辆的限界和重量设计带来负担。若真空断路器安装在柜内，由于绝缘的电气间隙要求，高压设备的高压带电点体积越小越有利于柜体或箱体的设计，由于现有真空断路器重量和体积较大，不利于柜体设计。
第二，真空断路器通过底板组装安装在车体上，底板组装上设有安装接口。因应用车辆不同，对真空断路器的安装要求也有不同，即需要不同的安装接口，而一种型号的真空断路器只对应带特定安装接口的底板，导致不同型号的真空断路器之间互换性差。
发明内容
现有的真空断路器不适应雨雪天气、可靠性较低，体积大、重量大、互换性不良。本发明的目的在于，针对上述现有技术的不足，提供一种横式一体绝缘真空断路器，能够适应雨雪天气、可靠性高，体积小、重量轻，互换性好。
为解决上述技术问题，本发明所采用的技术方案是：
一种横式一体绝缘真空断路器，包括低压控制部分、底板组装、弹簧支架组装、绝缘推杆、真空开关管组装和绝缘子，其中低压控制部分装于底板组装底部，低压控制部分通过弹簧支架组装、绝缘推杆与真空开关管组装传动相连，其特点是所述绝缘子为同时提供极间绝缘和对地绝缘的一体成型结构，一体式绝缘子的一端通过支柱与底板组装相连，一体式绝缘子的轴线与底板组装平行。
借由上述结构，由于将极间绝缘和对地绝缘做成一个整体，同时一体式绝缘子的轴线与底板组装平行，从而一体式绝缘子横置安装，水和雪不会在一体式绝缘子的伞裙上堆积而导致形成导电路径，能应对雨雪、雾霾等严酷的气候条件，可靠性高。无需通过增加一体式绝缘子高度来增加可靠性，使得体积和重量较小。
进一步地，所述一体式绝缘子中部设置第一连接件，一体式绝缘子一端设有第二连接件，真空开关管组装和绝缘推杆置于一体式绝缘子内；真空开关管组装的一端与第二连接件相连，真空开关管组装的另一端与绝缘推杆一端相连；绝缘推杆的另一端通过弹簧支架组装与低压控制部分相连。
真空开关管组装和绝缘推杆置于一体式绝缘子内，进一步缩小了体积、减轻 了重量。
进一步地，所述一体式绝缘子中部的两个伞裙、上下两端的伞裙均为椭圆形，其余伞裙为圆形。
借由上述结构，既加大了高压输入端和输出端之间、输出端和接地端之间的电气间隙和爬电距离，又减小了一体式绝缘子的体积和质量。
进一步地，真空开关管组装和一体式绝缘子之间用硅胶填充，硅胶填充工艺采用特殊灌封设备完成。灌胶后的真空开关管组装或一体式绝缘子出现故障时，移除填充的硅胶后便可更换故障真空开关管组装或一体式绝缘子，不至于同时报废两者中未出现故障的部件。硅胶填充还可以增强一体式绝缘子的绝缘性能。
进一步地，第二连接件与一体式绝缘子之间设有第一密封圈。第一密封圈对绝缘子内部腔体起到防尘、防水作用。
作为一种优选方式，所述低压控制部分包括集成为一体化模块的驱动机构、储风缸和压力气缸。
低压控制部分集成设计为一体，能够实现低压控制部分的小体积设计，为适应不同车型对户内/户外真空断路器的复杂多变的接口要求提供技术基础。
进一步地，所述底板组装上设有第一安装接口，还包括附加底板，附加底板上开设与底板组装对应的通孔，底板组装可拆卸装于该通孔内，附加底板上设有第二安装接口。
借由上述结构，采用底板组装与附加底板的可变底板组合方案。底板组装上设有固定设计的第一安装接口，有利于实现产品的流水线生产。附加底板上的第二安装接口为根据不同车型安装需求设计的可变接口，可适应国内外不同车型对真空断路器的接口技术要求，使其具备高互换性。
进一步地，所述底板组装与附加底板之间设有第二密封圈。
作为一种优选方式，所述第一连接件和第二连接件均为法兰。
作为一种优选方式，第二连接件通过第一金属嵌件与一体式绝缘子可拆卸相连，一体式绝缘子通过第二金属嵌件与支柱可拆卸相连。
与现有技术相比，本发明结构简单、成本低廉，能够适应雨雪天气、绝缘性能好、可靠性高，体积小、重量轻，互换性好，适用于户外和柜体内安装。

具体实施方式
如图1至图15所示，本发明的一实施例包括低压控制部分1、底板组装2、弹簧支架组装3、绝缘推杆4、真空开关管组装5和一体式绝缘子6，其中低压控制部分1装于底板组装2底部，低压控制部分1通过弹簧支架组装3、绝缘推杆4与真空开关管组装5传动相连，所述一体式绝缘子6为同时提供极间绝缘和对地绝缘的一体成型结构，一体式绝缘子6的一端通过支柱7与底板组装2相连，一体式绝缘子6的轴线与底板组装2平行。
所述一体式绝缘子6中部设置第一连接件8，一体式绝缘子6一端设有第二连接件9，真空开关管组装5和绝缘推杆4置于一体式绝缘子6内；真空开关管组装5的一端与第二连接件9相连，真空开关管组装5的另一端与绝缘推杆4一端相连，绝缘推杆4的另一端通过弹簧支架组装3与低压控制部分1相连。
所述一体式绝缘子6中部的两个伞裙、上下两端的伞裙(共四个伞裙)均为椭圆形，其余伞裙为圆形。
所述真空开关管组装5和一体式绝缘子6之间用硅胶填充，硅胶填充工艺采用特殊灌封设备完成。灌胶后的真空开关管组装5或一体式绝缘子6出现故障时，移除填充的硅胶后便可更换故障真空开关管组装5或一体式绝缘子6，不至于同时报废两者中未出现故障的部件。
第二连接件9与一体式绝缘子6之间设有第一密封圈10。第一密封圈10对一体式绝缘子6内部腔体起到防尘、防水作用。
所述低压控制部分1包括集成为一体化模块的驱动机构11、储风缸12和压力气缸13。

所述底板组装2与附加底板14之间设有第二密封圈15。

第二连接件9通过第一金属嵌件16与一体式绝缘子6可拆卸相连，一体式绝缘子6通过第二金属嵌件17与支柱7可拆卸相连。
本实例中，发明对象是电控气动电保持型真空断路器，用于电力机车和动车组主电路的接通和开断，同时也能用于过载、短路保护。
除上述本发明中改进的技术方案外，本发明真空断路器继承了TDV10系列真空断路器产品的传动技术和控制原理。
本发明所述真空断路器通过真空开关管组装5实现高压电路接通和开断过程中电弧的熄灭。真空开关管组装5通过紧固件和绝缘推杆4、弹簧支架组装3固定在一体化绝缘子6内。一体化绝缘子6将极间绝缘和对地绝缘做成一个整体，能同时承载极间和对地绝缘。本发明中一体式绝缘子6轴线与安装平面平行，通过支柱7固定在安装平面上方，既能实现高绝缘性能，也能同时兼顾安装平面上方较低的产品高度。支柱7电位与车体相同，只需要满足电气间隙要求，不需要考虑雨雪灰尘对绝缘的影响，从而更容易满足各型电力机车和动车组对限界的要求。
本发明中，支柱7有多种结构形式，可以是分体的，通过紧固件连接；也可 以是单体的，作为一个整体承载和固定整个高压部分组装。支柱7可以是金属材质，也可以是绝缘材质。
安装在支柱7内的操纵杆与弹簧支架组装3相连，传递驱动力和回复力。驱动力由安装在底板上的低压控制部分1提供，低压控制部分1包括驱动机构11、储风缸12和压力气缸。驱动机构11的运动由低压控制部分1的控制盒控制。储风缸12内用于储存适合压力的压缩气体，本发明中，储风缸12创新设计成方形和圆形相结合的结构，在使用安装时，置于驱动机构11上方，且环抱压力气缸，实现低压控制部分1的集成化和模块化设计，这样可以充分利用压力气缸周边的空间。在满足真空断路器正常动作所需的气压条件下，将储风缸12体积尽可能缩小，从而减小真空断路器的体积和质量。
低压控制部分1和支柱7安装在底板组装2上。本发明中底板组装是一个可变组合，由底板组装2和附加底板14组成，能兼顾规模化生产和个性化小批量定制要求。底板组装2用于产品的批量化、流水线大规模生产。附加底板14可按客户要求定制，适应目前在运营车辆和正研制的车辆不同的接口要求。
本发明能同时实现市场对真空断路器的多样化和简统化需求，具备高绝缘性能：185kV雷电冲击电压、100kV工频耐受电压、外绝缘具备310mm电气间隙、1000mm的爬电距离；同时具备小体积(低压侧体积减少50％)和轻质量(质量降低30％)；能用于户外，可适用于国内外严酷环境气候和运用条件(海拔4000m；-40℃～+85℃；风速35m/s；雨6mm/min；400km/h速度等级等)；也能用于户内，满足高压电器柜/箱对带电体的低裸露要求。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是局限性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，这些均属于本发明的保护范围之内。
