目前,机车上总是安装有大功率的变流器,由于不同的机车对于变流器的外观、重量等方面的要求有所不同,因此不同的变流器对于变流器箱体的要求也不同。传统的变流器箱体通常是框架结构,且变流器箱体内置各种变流器的电气元件,因此变流器箱体必须有足够的强度去支撑变流器内部的各种电气元件的重量。
现有技术中,通过碳钢板焊接的方式或者镀铝锌钢板铆接的方式,以实现上述变流器箱体承载变流器内部的各种电气元件重量的强度的要求。但是,若单独采用碳钢板焊接后的变流器箱体容易发生变形,增加了工艺调整的复杂性;而单独采用镀铝锌钢板铆接后的变流器箱体的零件设计复杂、开发周期长,且镀铝锌钢板的价格较高,增加了整个变流器箱体的制造成本。
因此,考虑到上述问题,本发明提供一种变流器箱体和变流器,通过采用支撑框架中相邻两根支撑柱之间焊接的方式,与,多个结构板中所包括的防护板和支撑框架之间铆接的方式,在变流器采用上述变流器箱体后,变流器箱体可以拥有足够的强度去支撑变流器内部的电气元件的重量,有利于电气元件在变流器箱体的内部的合理布置,使得该变流器箱体能够更好地保护变流器内部的电气元件免受挤压,从而提高了变流器的可靠性,并且,提高了变流器箱体的美观性。
图1为本发明提供的一种变流器箱体的结构示意图,本发明提供的变流器箱体用于支撑变流器,如图1所示,该变流器箱体包括:支撑框架和多个结构板。
其中,支撑框架包括多个相互拼接的支撑柱1,且多个支撑柱1间隔设置,以围成用于容纳电气元件的空间,相邻两根支撑柱1之间焊接。
可选的,上述支撑框架的形状可以为柱体框架,也可以为如图1所示的长方体框架,图1中只标出了两个支撑柱1作为示意,具体实现时可以有多个支撑柱1。
可选的,多个支撑柱1的板材可以采用Q195碳素结构钢,也可以采用Q345低合金钢板,多个支撑柱1的板材的厚度可以为4毫米(Millimeter,简称:mm),也可以为3mm。而支撑柱1所采用的板材以及板材的厚度可以根据变流器箱体所承载的变流器决定,在本发明中,不对支撑柱1所采用的板材以及板材的厚度进行限定。例如,本发明中的支撑柱1的板材可以是厚度为4mm的Q345D低合金薄钢板,这里的“Q”指的是板材的屈服强度,“345”指的是板材的屈服强度为345兆帕(Megapascal,简称:MPa),“D”指的是板材的冲击温度为零下20摄氏度。
可选的,可以对焊接后的相邻两根支撑柱1进行喷漆处理,避免支撑框架生锈,影响变流器箱体的美观性。
具体实现时,采用焊接的方式带来的有益效果为:焊接后的支撑柱1之间的连接性能好、焊接结构刚度大,整体性好。
其中,多个结构板中包括位于支撑框架外侧表面的防护板3,防护板3和支撑框架之间通过铆接件2铆接。对应的,需在各个防护板3和支撑框架上开设铆接件孔,铆接件2的种类、尺寸、数量和分布均可由技术人员以及该变流器箱体内所容纳的电气元件的重量来设定。在本发明中,不对铆接件2进行限定。
图1中,只标出了三个铆接件2,以及四个防护板3作为示意,具体实现时可以有多个铆接件2以及多个防护板3。
具体实现时,采用铆接的方式带来的有益效果为:铆接可以避免防护板3发生变形,并且铆接的工艺方法简单,可以提高整流器箱体的外表面的平整度。
值得说明的是,这里的防护板3不属于变流器箱体的主要承重部位,防护板3所起到的主要作用是为了辅助变流器箱体支撑变流器。在本发明中,不对变流器箱体的防护板3的板材厚度进行限定。例如,本发明中的变流器箱体的防护板3的板材可以采用厚度为2mm的0Cr18Ni9不锈钢材质,可以采用厚度为3mm的0Cr18Ni9不锈钢材质,还可以采用其他厚度的不锈钢材质。
可选的,变流器箱体的尺寸可根据容纳的变流器的尺寸来设定。在 本发明中,不对变流器箱体的尺寸进行限定。
本发明提供的变流器箱体,包括支撑框架和多个结构板。由于该变流器箱体采用支撑框架中相邻两根支撑柱之间焊接的方式,与,多个结构板中所包括的防护板和支撑框架之间铆接的方式,在变流器采用上述变流器箱体后,变流器箱体可以拥有足够的强度去支撑变流器内部的电气元件的重量,有利于电气元件在变流器箱体的内部的合理布置,使得该变流器箱体能够更好地保护变流器内部的电气元件免受挤压,从而提高了变流器的可靠性,并且,提高了变流器箱体的美观性。
图2为本发明提供的另一种变流器箱体的结构示意图,图3为本发明提供的变流器箱体中支撑框架的结构示意图,图4为本发明提供的变流器箱体的主视图,本发明提供的变流器箱体用于支撑变流器,如图2至图4所示:
可选的,上述防护板3可以是位于支撑框架前侧的柜门板,可以是位于支撑框架后侧的后门板,可以是位于支撑框架侧方的侧板3a,也可以是位于支撑框架顶部的顶板3b。为了介绍变流器箱体内部的结构,图2中未示出位于支撑框架前侧的柜门板和支撑框架后侧的后门板。并且,如图2所示,以图2中的A面作为变流器箱体的正面,即支撑框架的前侧方向;以图2中的B面作为变流器箱体的侧面,即支撑框架的侧方;以图2中的C面作为变流器箱体的上面,即支撑框架的顶部方向;以图2中的D面作为变流器箱体的底面,即支撑框架的底部方向。上述支撑框架的前侧、侧方、顶部、底部等方向只是一种可能性的示意。
可选的,变流器箱体的各侧面以及底面可以根据需要开设通孔,供导线或线缆穿过。例如可以在变流器箱体的两个侧面和变流器箱体的底部开设通孔,以便高压线缆、低压线缆以及其他导线的穿过。
可选的,柜门板和后门板可以通过平头铆钉与支撑框架铆接,而其他防护板3例如上述侧板3a、顶板3b等可以通过圆头铆钉与支撑框架铆接。之所以采取这样的铆接方式,是因为柜门板位于变流器箱体的支撑框架的前侧方向,后门板位于变流器箱体的支撑框架的后侧方向,当从变流器箱体的支撑框架的前侧方向,或者,变流器箱体的支撑框架的后侧方向观察时,平头铆钉铆接后的柜门板和后门板的平整度更高,进一 步也有利于前门板和后门板的安装,从而使得变流器箱体更加美观。
可选的,多个结构板中除了包括防护板3以外,还可以包括支撑板,如图2所示,防护板3位于支撑框架外侧表面,而支撑板水平设置在支撑框架的内部并与支撑柱1焊接,支撑板用于支撑位于支撑框架内的电气元件,并且,位于变流体箱体内部的不同位置的支撑板所支撑的电气元件有所不同。
可选的,支撑板的板材可以采用Q345碳素结构钢,多个支撑板的板材的厚度可以为4毫米(Millimeter,简称:mm),也可以为3mm。而支撑板所采用的板材以及板材的厚度可以根据变流器箱体所容纳的变流器决定。在本发明中,不对支撑板所采用的板材进行限定。例如,本发明中的支撑板的板材可以是厚度为3mm的Q345D低合金薄钢板。
可选的,支撑板的板材可以为不锈钢材质,以此避免上述电气元件在拆装的过程中与喷漆后的支撑框架发生油漆的剐蹭。
可选的,支撑框架的支撑柱1可以围成多种空间形式。例如,如图2至图4所示,支撑框架的支撑柱1可以围成上下层叠设置的第一长方体空间5和第二长方体空间6,且第一长方体空间5在高度方向上的横截面位于第二长方体空间6在高度方向上的横截面内部。
当变流器箱体的内部被分割为不同的空间后,电气元件可以被放置在变流体箱体内的不同空间。不同空间内放置的不同电气元件可以实现不同的作用。并且,电气元件的安装位置可以根据安装电流器箱体的机车类型决定。在本发明中,不对电气元件的安装位置进行限定。
可选的,变流器箱体内可以具有多个支撑板,且支撑板在支撑框架内排列为至少两个支撑层;至少两个支撑层中包括用于支撑电容和功率模块的第一支撑层,以及用于支撑高压元器件和低压元器件的第二支撑层,所述第二支撑层位于所述第一支撑层上方。例如,如图2至图4所示,支撑板在支撑框架内排列为多个支撑层。
具体实现时,根据不同的变流器内部的电气元件的组成,变流器箱体内部用于支撑电气元件的支撑板的具体数量可以根据变流器的种类进行确定。为了更加清晰的说明该变流器箱体所容纳的电气元件在变流器箱体内部的安装位置,下面以图4所示的变流器箱体的内部的结构为例进 行说明:
如图4所示,第一支撑板4a用于支撑变流器内部的膨胀水箱等,第二支撑板4b用于支撑变流器内部的各类电阻、斩波电流传感器、隔离开关、风扇等,第三支撑板4c用于支撑变流器内部的低压元器件、牵引控制单元等,第四支撑板4d用于支撑变流器内部的牵引斩波功率模块以及中间支撑电容,第五支撑板4e用于支撑变流器内部的逆变功率模块以及中间支撑电容,第六支撑板4f用于支撑变流器内部的水泵、压力传感器、温度传感器,第七支撑板4g用于支撑变流器内部的各类接触器、输入电流传感器、电源、电压传感器、输入接口等,第八支撑板4h用于支撑变流器内部的二次滤波电容,第九支撑板4i用于支撑变流器内部的输出电流传感器、输出接口等。
可选的,变流器可以包括不止一个牵引斩波功率模块,也可以包括不止一个逆变功率模块。对应的,变流器箱体内部所包括的用于支撑牵引斩波功率模块以及中间支撑电容的第四支撑板4d可以不止一块,变流器箱体内部包括的用于支撑逆变功率模块以及中间支撑电容的第五支撑板4e也可以不止一块。
可选的,可以在支撑上述低压元器件、牵引控制单元等的第三支撑板4c上、支撑上述牵引斩波功率模块以及中间支撑电容的第四支撑板4d上、支撑上述逆变功率模块以及中间支撑电容的第五支撑板4e上和支撑上述二次滤波电容等电气元件的第八支撑板4h上设置滑轨,滑轨的滑动方向朝向支撑框架的前方。设置滑轨的原因是,变流器内部的牵引斩波功率模块、逆变功率模块、二次滤波电容等电气元件的重量过大,因此安装滑轨后,一方面可以将电流器内部的电气元件很好地固定在支撑板上,另一方面,便于重量过大的牵引斩波功率模块、逆变功率模块以及二次滤波电容更容易地安装于变流器箱体上。
值得说明的是,除了上述九个支撑板以外,变流器箱体的内部还可以添加其他支撑板,用来支撑将来在变流器箱体内部安装其他的电气元件。对应的,若在变流器箱体的内部添加其他支撑板,那么上述九个支撑板的位置和数量均有可能发生变化。
可选的,如图2所示,本发明提供的变流器箱体还可以包括四个吊环 螺钉7,四个吊环螺钉7分别位于支撑框架的对应第二长方体空间6的四个上顶角的位置。
具体实现时,可以从吊环螺钉7的结构型形式、尺寸、技术要求、起吊重量等方面综合考虑,选择吊环螺钉7的类型。例如,可以在变流器箱体中第二长方体空间6的四个上顶角的位置固定安装4个M30吊环螺钉7。
当使用工装工具垂直起吊该变流器箱体时,可以完成变流器以及变流器箱体的搬运吊装。由于变流器内部的电气元件的布局已经临界整个变流器的总高度,安装四个吊环螺钉后,一方面,不仅不会影响变流器箱体内部的电气元件的布局,还可以满足变流器箱体内部的电气元件之间的电气间隙的要求,并且也不会占用变流器箱体的总高度空间;另一方面,当变流器以及变流器箱体吊装到对应的机车上后,不需要拆掉吊环螺钉,从而避免吊环螺钉无处安放或者吊环螺钉丢失的情况的出现。
本发明还提供一种变流器,该交流器通过采用上述变流器箱体,包括支撑框架和多个结构板,支撑框架包括多个相互拼接的支撑柱,且多个支撑柱间隔设置,以围成用于容纳电气元件的空间,相邻两根支撑柱之间焊接;多个结构板中包括位于支撑框架外侧表面的防护板,防护板和支撑框架之间通过铆接件铆接,在变流器采用上述变流器箱体后,变流器箱体可以拥有足够的强度去支撑变流器内部的电气元件的重量,有利于电气元件在变流器箱体的内部的合理布置,使得该变流器箱体能够更好地保护变流器内部的电气元件免受挤压,从而提高了变流器的可靠性,并且,提高了变流器箱体的美观性。
