具体实施方式
下面结合附图与具体实施方式对本发明作进一步详细描述：
如图1至图5所示，一种轨道车辆用高压设备箱，设置在轨道车辆车下设备舱，用于安装受电设备。
如图11至图14所示，设备箱包括箱体1，箱体1的形状为长方体，包括主骨架2和设置在主骨架2上的顶板7、主侧板8、后侧板、金属通过筒安装板11和两端端板12，后侧板包括侧顶板9和侧底板10，主骨架2包括底架3、顶架4和两端的端架5。端架5为方形，在端架5上焊接端板12，在端架5底部设置连接架6与底架3固定，连接架6倾斜设置，在端架5顶部通过顶架4与另一端端架5固定连接。顶架4为两根贯通箱体两端的横架，设置在端架5方形的顶部两角位置，加强连接强度。
如图16所示，端架5、顶架4和连接架6采用中空型材，减少自重，提高强度，在中空型材上设置有沿边13，设置沿边13的目的是为了方便与端板12、侧顶板9或侧底板10焊接，提高焊接强度，沿边13的设置方向与端板12、侧顶板9或侧底板10设置方向一致，沿边13的设置位置与 中空型材的表面之间形成一定距离高度差，端板12、侧顶板9或侧底板10与沿边13的一侧表面紧贴并焊接固定，使端板12、侧顶板9或侧底板10焊接固定后与中空型材表面平齐。
如图17和图18所示，在箱体1顶部，即主骨架2顶架4的上方焊接固定有顶板7，顶板7由多块板拼接而成，多块板焊接固定在一起，利于生产，减少自重提高强度。顶板7截面呈“L”形，从箱体1侧面向下弯折一段距离，并与箱体1两侧的主侧板8和侧顶板9插接后焊接固定，在顶板7与主侧板8或侧顶板9的连接位置，顶板7与主侧板8或侧顶板9之间形成错位，便于插接后焊接，采用插接有利于提高连接强度。
在箱体1两侧分别焊接固定主侧板8和后侧板，其中主侧板8为一体件，四周与顶板7、端架5、连接架6和底架3焊接固定。后侧板包括侧顶板9和侧底板10，侧顶板9由多块板拼接后焊接组成，侧顶板9底部与侧底板10插接后焊接固定，在侧顶板9和侧底板10的连接位置，侧顶板9和侧底板10之间形成错位，用于插接后焊接固定，插接有利于提高连接强度。金属通过筒安装板11与侧顶板9和侧底板10焊接固定，焊接固定成一体的金属通过筒安装座11、侧顶板9、侧底板10与顶板7、端架5、连接架6和底架3焊接固定。
如图19所示，侧底板10的底部从箱体1底部向内弯折，便于侧底板10与底架3焊接，侧底板10的底部设置有“U”形过渡角14，有利于箱体1减重和提高强度。
如图3和图4所示，箱体1的底部为主骨架2的底架3，在底架3上设置有三个检修盖安装孔，设置三个检修盖15固定在底架3上，用于箱内设备的维修，还设置有锁闭装置16进行锁闭，当实施作业或检修时，必须操作锁闭装置16后，才可以打开检查盖15，确保安全。
顶板7、主侧板8、后侧板、金属通过筒安装板11和两端端板12均采用铝合金，满足耐高寒要求，其中顶板7和后侧板采用波浪型材结构，降低箱体1重量，提高强度。
如图11和图12所示，在顶板7上设置有避雷器安装接口17，在金属通过筒安装板11上设置有金属通过筒安装接口18，在主侧板8上设置有 过滤器安装接口19、真空断路器安装接口20、闭锁装置安装接口21、电缆接头安装接口22、线夹安装接口23。
如图1至图3所示，箱体1采用密封结构，在箱体1内设置有真空断路器24、电缆接头25、避雷器26，避雷器26通过避雷器安装接口17固定在顶板7上，真空断路器24和电缆接头25分别通过真空断路器安装接口20和电缆接头安装接口22固定在主侧板8上，真空断路器24和电缆接头25通过连接线28连接，真空断路器24和避雷器26通过连接线28连接。在箱体1上设置有金属通过筒27连接至牵引变压器(未示出)，真空断路器24和牵引变压器通过穿过金属通过筒27的连接线28连接，金属通过筒27采用伸缩式结构，通过金属通过筒安装接口18固定在金属通过筒安装板11上，内部设置密封条，保证密封性。
如图3所示，在箱体1上设置有线夹29和过滤器30，线夹29和过滤器30分别通过线夹安装接口23和过滤器安装接口19设置在主侧板8上，线夹29用于密封进入箱体1的线缆，过滤器30用于适应通过隧道时压力变化与外界大气压进行交换。
如图15所示，线夹29包括焊接在箱体1上的固定安装块29a和栓接固定在箱体1上的活动安装块29b，固定安装块29a和活动安装块29b之间栓接固定，在固定安装块29a和活动安装块29b上分别设置有一半的椭圆状安装孔29c，线缆通过椭圆形安装孔29c进入箱体1，在固定安装块29a和活动安装块29b贴合栓接后，固定安装块29a和活动安装块29b夹紧椭圆形安装孔29c中的线缆，将其密封。
为保证箱体1密封性，真空断路器24、电缆接头25、金属通过筒27、过滤器30、检查盖15均采用橡胶垫密封。
箱体1增大尺寸使真空断路器24、电缆接头25、避雷器26的带电部分之间以及带电部分与箱体1箱壁之间的最小电气间隙为310mm-320mm，在本实施例中优选315mm，满足OV4过电压等级要求(GB/T21413.1)。
如图6和图7所示，箱体1在车辆宽度方向上的两端，即箱体1端板12所在端延伸至裙板31处，车辆裙板31的底部固定在箱体1上。主骨架2的端架5与底架3相互垂直，之间设置有倾斜的连接架6，连接架6倾斜 35°设置，使箱体1靠近裙板31的两端的底部具有避让缺口。
在连接架6所在的避让缺口位置设置有两个裙板安装座34，裙板安装座34为具有两个侧面的连接片，形状呈“L”形，裙板安装座“L”形的一端连接在端架5的底部，另一端连接在底架3的端部。在裙板安装座34与底架3固定的一侧面上设置有两个开孔，在裙板31的底部套有两个螺栓，两个螺栓分别穿过两个开孔，并通过螺母固定吊挂在裙板安装座34上。
通过连接架6的倾斜设置形成避让缺口，裙板31的底部可以吊挂固定在避让缺口处，使箱体1在车宽方向尺寸增加后能够避开裙板，箱体1增加尺寸使箱内电气设备能够满足电气间隙要求。车辆裙板31与箱体1的固定连接方式，还保证了车辆车下设备舱的密封性，提高了设备舱内的清洁度，提高了车辆抗大风沙的能力。
如图8至图10所示，箱体1在车辆长度方向(箱体宽度方向)的两侧与车辆两根邻近的车体底梁32平齐，箱体1的顶部延伸至车体底梁32上方。如图14和图20所示，在箱体1上设置有吊座35，吊座35用于与车体底梁32固定，将箱体1吊挂固定在车体底梁32上，吊座35的形状为
Figure PCTCN2015094665-appb-000001
形，吊座35延车辆长度方向设置并贯通箱体1两侧，吊座35与主骨架2焊接固定，吊座35在箱体1宽度方向的两侧侧面处向下延伸一定距离，在本实施例中，延伸距离为93mm，在延伸部的底端向外侧突出设置一块连接块35a形成安装座结构，在连接块35a上设置有用于吊挂箱体1的开孔，连接块35a的一侧侧面与车体底梁32的底面贴紧并通过螺栓固定。本实施例中，设置两个吊座35，由于设置了吊座35，故顶架4被分割成三段与吊座35焊接固定。
由于吊座35两端的连接块35a与车体底梁32底面紧贴，故位于连接块35a所在水平面上方的箱体1结构就延伸至车体底梁32上方，吊座35在箱体1宽度方向的两侧侧面处向下延伸的距离即为箱体1顶部伸入车体底梁32上方的长度，在本实施例中为93mm。吊座35的设置方式，使得在车体底梁32不做改进的情况下，箱体1能够增大尺寸，不受到车体底梁32的约束。
箱体1在车辆长度方向的两侧侧面之间加宽，与两根邻近车体底梁32 平齐，并且通过吊座35的改进，使箱体1在高度方面向上延伸至车体底梁32上方，箱体1的尺寸大幅增加，满足了箱内电气设备电气间隙要求。由于箱体1与车体底梁32的连接点位于箱体1侧面上，如果只是在侧面设置单独的吊座结构，则结构强度不足，故吊座35采用了贯通箱体1两侧侧面的结构，满足强度要求。
箱体1的底部向下延伸，并裸露在车体底板33外，在本实施例中，箱体1的底部与车体底板33平齐，并且箱体1的底部兼做车体底板33的一部分。箱体1底部向下延伸并兼做车体底板33的一部分，在不对车体底板33进行改进的情况下，使箱体1增大尺寸成为可能，增大尺寸的箱体1使箱体1内电气设备满足电气间隙要求。
如图9所示，在箱体1上设置有安装条36，安装条36用于与车体底板33固定，安装条36延车辆宽度方向(箱体长度方向)贯通设置，设置位置位于箱体1两侧侧面的底部，安装条36的高度与车体底板33平齐，安装条36的截面呈“凹”形，凹形开口朝向车体底板33侧，车体底板33插接固定在凹形开口内。在凹形开口内设置有用于扣住车体底板的上下凸起结构36a，车体底板33插入部分的形状与上下凸起结构36a配合，使车体底板33插入后不会因车辆震动而退出凹形开口。车体底板33与箱体1的固定连接方式，保证了车辆车下设备舱的密封性，提高了设备舱内的清洁度，提高了车辆抗大风沙的能力。
综上所述，本发明所述的一种轨道车辆用高压设备箱，在箱体两端底部倾斜设置避让口，不仅使箱体1的尺寸能够大幅增加，满足箱内设备电气间隙，还为裙板31提供了安装座。箱体1顶部延伸至车体底梁32上方、箱体1在车辆长度方向的两侧与两根邻近车体底梁32平齐、箱体底部兼做车体底板33的一部分，进一步加大了箱体1尺寸，满足箱内设备电气间隙。车辆裙板31和车体底板33与箱体1的固定连接方式，保证了车辆车下设备舱的密封性，提高了设备舱内的清洁度，提高了车辆抗大风沙的能力。箱体1各板采用铝合金材质，满足耐高寒要求。设备箱采用密封结构，其主骨架2和各板的设置方式，在箱体1增大尺寸后，有效的减少了设备箱的重量，提高了设备箱的强度。顶板7和后侧板采用波浪型材结构，进一 步降低设备箱重量，提高强度。通过设置线夹29进一步增强了设备箱自身的密封性，设置过滤器30适应通过隧道时压力变化与外界大气压进行交换。箱体1内真空断路器24、电缆接头25、避雷器26的带电部分之间以及带电部分与箱体1箱壁之间的最小电气间隙为315mm，使设备箱满足高海拔运行的要求。
如上所述，结合附图所给出的方案内容，可以衍生出类似的技术方案。但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
