技术领域

具体实施方式
下面将结合附图对本申请实施例作进一步描述。
首先说明一下本申请实施例提供的插接箱的应用场景，本申请提供的插接箱应用于数据中心内密集型母线的连接。如图2中所示的现有技术中数据中心内密集型母线的连接。密集型母线包括两种类型的母线：主路母线和支路母线。主路母线沿数据中心延伸，作为主干路提供电能。支路母线作为分支结构，用于给不同的设备进行供电。在主路母线与支路母线连接时，主路母线会配备一个带开关的插接箱，支路母线也会配备一个带开关的始端箱，通过线缆将插接箱和始端箱连接，实现主路母线和支路母线的导电连通。在上述配电电路中要求两个开关，这会增加电路上的失效点，增加配电电路失效的可能性。为此本申请实施例提供了一种改善数据中心内主路母线和支路母线连接效果的插接箱。下面结合具体的附图以及实施例对其进行详细的描述。
图3示出了本申请实施例提供的插接箱100的应用示意图。插接箱100主要包括箱体20以及固定设置在箱体20内的开关单元10。箱体20用于分别连接主路母线200和支路母线300，主路母线200和支路母线300之间仅有一个断点(箱体20所在位置)。开关单元10分别与主路母线200和支路母线300连接，在开关单元10关闭时，主路母线200和支路母线300导通；在开关单元10打开时，主路母线200和支路母线300断开连接。
图4示出了本申请实施例提供的插接箱的内部结构示意图。箱体20包括外罩21、第一连接端子22及第二连接端子27。第一连接端子22与外罩21固定连接，并可用于与主 路母线200连接；第二连接端子27与外罩21固定连接，并用于与支路母线300连接。
开关单元10通过第一连接器24与第一连接端子22导电连接。示例性的，第一连接器24通过第一铜排23与第一连接端子22连接。第一铜排23作为一个转接件，固定设置在外罩21内。在设置时，可通过第一铜排23的长度以及形状调整第一连接器24的设置位置，以方便第一连接器24与开关单元10对应连接。
开关单元10通过第二连接器25与第二连接端子27导电连接。示例性的，第二连接器25通过第二铜排26与第二连接端子27连接。第二铜排26作为一个转接件，固定设置在外罩21内。在设置时，可通过第二铜排26的长度调整第一连接器24的设置位置，以方便第一连接器24与开关单元10对应连接。
参考图4中带箭头的直线，带箭头的直线示出了电流的流动方向。当开关单元10闭合时，主路母线的电流经第一连接端子22流入到插接箱、依次流经第一铜排23、第一连接器24、开关单元10、第二连接器25、第二铜排26后，通过第二连接端子27流出到支路母线。
通过上述描述可看出，本申请实施例提供的插接箱可直接与主路母线和支路母线连接，主路母线和支路母线之间仅存在一个断点(开关单元)，相比现有技术中图1所示的主路母线和支路母线采用两个开关的连接方式，降低了主路母线和支路母线连接时的失效点，从而可提高主路母线和支路母线在连接时的可靠性。
在插接箱使用时，不可避免的会存在开关单元更换或维修的需求。为此本申请实施例提供的开关单元以可拆卸的方式插入到箱体20内。在需要维修时，可直接将开关单元从箱体内取出即可。
参考图5，图5示出了第一连接器24的结构示意图。第一连接器24包括第一插座242和第一插针241，第一插座242和第一插针241可插拔连接。其中，第一插针241与开关单元固定连接，第一插座242与第一铜排固定连接。同理，第二连接器采用与第一连接器相同的结构，在此不再赘述。
在开关单元固定在箱体内时，第一插针241一一对应插入第一插座242并导电连通；第二连接器的第二插针一一对应插入第二插座并导电连通。在开关单元需要从箱体内取出进行更换或者维修时，第一插针241从对应的第一插座242中拔出，第二插针从对应的第二插座中拔出，实现电路的断开。
应理解，上述插针和插座的配合可采用不同的形式，如采用梅花式的插座和梅花形的插针配合，或者采用鸭嘴式的插座和片状的插针配合形式，在本申请中不做具体限定。
由上述描述可看出，通过第一连接器和第二连接器的配合，实现了开关单元在插拔连接时的电路连接。在开关单元出现故障时，可直接将开关单元从箱体中取出进行维修，无需将整个插接箱取下，从而降低了维修的难度。另外，在采用开关单元与箱体插拔连接时，当取出开关单元时，仍可保持第一连接端子与主路母线连接、第二连接端子与支路母线连接。当再次将开关单元插入到箱体内时，只需第一连接器和第二连接器进行插拔连接即可，从而实现了热插拔，降低了插接箱维修的难度。
参考图6，图6示出了本申请实施例提供的插接箱的电路示意图。本申请实施例提供的插接箱的电路包括主电路以及分支电路。
主电路为上述的第一连接端子、第一铜排、第一连接器、开关单元、第二连接器、第二铜排及第二连接端子组成的电路，上述主电路中，以开关单元10为划分点，将主电路 划分为输入端和输出端。
分支电路为对主电路监测以及控制的电路。分支电路包括监控电路，用于检测主电路连接情况以及对主电路的输入和输出采样并监控主电路，上述采用包括但不限定电压采样、电流采样等。示例性的，监控电路包括监控模块80，以及与监控模块80连接的电压传感器90、电流互感器50或者其他的电子器件。作为一个可选的方案，监控电路还包括用于检测主电路的输入和输出的温度。
为保证插接箱的工作温度，本申请实施例提供的分支电路还包括风扇60，风扇60用于降低插接箱内的温度，以保证插接箱内的器件可靠地工作。
分支电路还可包括供电电路，供电电路包括电源模块70从输入端取电，可对监控电路供电。作为一个可选的方案，可在供电电路的输入侧设置可熔断保护电路的保险丝，以提高供电电路的安全性。
分支电路还包括保护电路，保护电路包括防雷器30和防雷空开40。防雷器30通过防雷空开40与主电路的输出端连接，可释放过电压能量，以保护电路。
分支电路还包括从输入端取电的指示灯400，指示灯400用于指示输入端的来电提醒。
图7示出了一种具体的插接箱的分解示意图。主电路和分支电路的结构均设置在插接箱的箱体内。下面结合图7来说明一下图6所示的电路中的器件排布。
首先建立参考坐标系XYZ，原点O为箱体的一个顶角，方向X、方向Y和方向Z平行于箱体相邻的三个侧边。
外罩包括本体211以及与本体211转动连接的箱盖212。本体211内的空间被划分为第一腔室和第二腔室。第一腔室用于容纳开关单元10、第一连接器、第二连接器、第一铜排23、第二铜排80、电源模块70、风扇60等。第二腔室用于容纳电压传感器、电流互感器50、防雷器30、防雷空开40等器件。
本体211包括五个侧板以及隔板2114。为方便描述，将四个侧板分别命名为下侧板2112、左侧板2113、右侧板2111、上侧板(图中未示出)及下侧板2115。四个侧板通过螺纹连接件(螺栓或螺钉)固定连接围成容纳主电路和分支电路的各个器件的空间。
隔板2114与下侧板2112相对设置，并可拆卸的与四个侧板中的至少两个相对的侧板或两个相邻的侧板连接，如隔板2114与上侧板及下侧板2112固定连接，或者隔板2114与左侧板2113及下侧板2115。隔板2114与对应的侧板的连接可通过螺纹件(螺栓或螺钉)连接或采用卡合的方式连接。
在隔板2114与对应的侧板连接时，遮挡容纳在本体211内的器件。如第一铜排、第二铜排等器件。另外，隔板2114上设置有用于外露部件的镂空结构。示例性的，开关单元10、监控模块80可穿过隔板2114外露。
箱盖212作为一个保护器件，用以保护本体211内的器件以及隔板2114上的器件，在箱盖212盖合在本体211时，箱盖212遮挡隔板2114，以避免意外碰触到开关单元10。作为一个可选的方案，箱盖212还可用于设置器件，如用于指示输入端来电提醒的指示灯，以及上述监控电路中用于监控主电路电压、电流、温度等性能的指示器件。在箱盖212上设置上述部件时，可无需打开箱盖212即可检测插接箱的运行情况。
箱盖212与本体211的一个侧板转动连接，示例性的，箱盖212与下侧板2115转动连接，在箱盖212打开时，箱盖212可依靠自身重量下翻到本体211的下方，从而使得隔板2114外露，避免打开的箱盖212影响到工人的操作。或者箱盖212与其他侧板转动连接， 在此不再一一示例。
参考图8，图8示出了本体内第一铜排23和第二铜排26的排布示意图，图8中的部分标号可参考图7中的相同标号。第一铜排23位于第一腔室内，并与本体固定连接。第一铜排23具有第一连接端以及第二连接端，第一连接端与第一连接端子22固定连接，第二连接端与第一连接器24的第一插座固定连接。
本体内设置有一个用于支撑第一铜排23的第一支架214，第一支架214固定在下侧板2112，如第一支架214通过螺纹连接件(螺栓或螺钉)或者铆钉与下侧板2112固定连接。第一铜排23的第二连接端位于第一支架214上，在第一连接器的第一插针插入到第一插座时，通过第一支架214给第一插座提供支撑力。
在本申请实施中，第一铜排23具有多个，且多个第一铜排23可根据本体内的空间进行折弯，具体的折弯形式在本申请实施例中不做具体限定，只需保证各个铜排之间满足电隔离的要求即可。另外，第一铜排23的第二连接端为自由端，因此可发生一定的弹性形变。在第一插针和第一插座为多个时，可通过第一铜排23的弹性形变降低对对位精度的要求。
第二铜排26位于第二腔室内并与本体固定连接。第二铜排26具有第一连接端和第二连接端，第二铜排26的第一连接端延伸到第一腔室内并通过第二支架213支撑。第二铜排26与第二支架213的配合方式与第一铜排23与第一支架214的配合方式相同，在此不再赘述。
参考图9，图9示出了开关单元与外罩之间进行插拔的示意图。开关单元10放置在箱体内的第一腔室，并通过第一连接器与第一铜排连接，通过第二连接器与第二铜排连接，实现主路电路的连接。
开关单元10包括壳体11以及断路器开关12，断路器开关12通过连接件固定在壳体11内。上述壳体11作为断路器开关12的承载结构，断路器开关12可拆卸的固定在壳体11内，如断路器开关12通过螺纹连接件(螺栓或者螺钉)与壳体11固定连接。作为一个可选的方案，第一连接器的第一插针及第二连接器的第二插针分别与壳体11固定连接，断路器开关12的端子通过螺栓或者螺钉分别第一插针及第二插针固定连接。在需要维修开关单元10时，可将开关单元10从箱体中拔出，之后将断路器开关12从壳体11中拆卸下进行维修或者更换。
壳体11除承载断路器开关12外，还作为开关单元10与本体211连接的器件。在配合时，壳体11和本体211之间可设置导向结构，如导向滑轨和导向槽，导向滑轨设置在本体211和壳体11中的一个部件上，导向槽设置在本体211和壳体11的另一个部件。在装配时，通过导向滑轨和导向槽的配合，方便壳体11插入到本体211内，同时也方便了第一插针和第一插座之间、第二插针和第二插座之间的对位。
电压传感器、电流互感器分别与第二铜排连接。电流互感器用于检测流经第二铜排的电流，电压传感器用于检测第二铜排上的电压，以完成对主电路的电压采样和电流采样。防雷空开40与防雷器30串联，防雷器30与本体211的地连接，防雷空开40与第二铜排连接，通过防雷器30和防雷空开40组成的保护电路可释放过电压能量，保护主电路。
作为一个可选的方案，一并参考图7及图9，监控模块80与壳体11插拔连接。监控模块80可通过设置在壳体11的插槽与壳体11固定连接。在开关单元10固定在箱体内时，监控模块80可与本体211内设置的电路板81导通，该电路板81用于将监控模块80与上 述的电流互感器、电压传感器等器件连接，应理解监控模块80与电路板81之间通过连接端子(如公母连接端子)插拔连接。在开关单元10从箱体内拔出时，监控模块80跟随开关单元10一起拔出，并与电路板81断开连接。
应理解，在本申请实施例中监控模块不仅限于图9所示的设置方式，监控模块还可采用与本体211插拔的方式实现与电路板的插拔连接。此时监控模块80和开关单元10为相互独立的结构，两者可分别进行插拔。
图10示出了隔板2114与本体的配合示意图。隔板2114设置有避让孔，以保证本体内的部分部件可外露在隔板2114外进行操作。示例性的，隔板2114包括第一避让孔、第二避让孔和第三避让孔。其中，第一避让孔用于避让断路器开关12，断路器开关12的操作手柄可外露在隔板2114外，因此可直接操作断路器开关12。第二避让孔用于避让监控模块80，监控模块80可穿过第二避让孔后插入到开关单元的壳体内。在监控模块80需要更换时，可不拆卸隔板2114，直接插拔更换监控模块80。第三避让孔可避让防雷器和防雷空开，使得防雷器和防雷空开的部分结构外露在隔板2114外，从而可避免影响到隔板2114的设置。
在插接箱正常使用时，当需要对断路器开关12操作时，或者更换监控模块80时，可直接打开箱盖进行上述操作。当需要更换断路器开关12时，可将隔板2114取下，直接将开关单元从本体内拔出即可。由上述描述可看出，在对插接箱内的器件进行更换或者维修时，无需断开插接箱与主路母线和支路母线的连接，可实现热插拔开关单元。相比于现有技术中对插接箱维修时，需要将插接箱从主路母线或支路母线取下的情况，本申请实施例提供的插接箱，降低了维修难度；另外，在修为后只需将维修或者更换后的器件安装到原来的位置即可，无需拆卸与主路母线和支路母线的连接。
参考图11及图12，为方便开关单元10从箱体内拔出，本申请实施例提供的插接箱还提供了一助力结构13。该助力结构13可用于帮助克服第一插针和第一插座之间、第二插针和第二插座之间的连接力，以方便将开关单元10拔出。在本申请实施例不具体限定助理结构13的个数。如可采用两个助力结构13，两个助力结构13对称设置。
助力结构13包括设置在箱体内的助力销131，以及设置在开关单元并用于与助力销131配合的助力扳手132。助力销131固定在箱体内并位于开关单元10的一侧。助力扳手132与开关单元10的壳体转动连接。
助力扳手132具有工作端1321，工作端1321具有与助力销131配合的缺口1322。在工作端1321沿顺时针转动到一定位置时，缺口1322卡合在助力销131，再次转动助力扳手132时，缺口1322的侧壁抵压在助力销131上，助力销131作为一个支撑点支撑助力扳手132再次转动，以将开关单元从壳体中拉出。
作为一个可选的方案，助力扳手132还包括手柄1323。手柄1323与工作端1321可拆卸的连接。在需要使用助力扳手132时，可将手柄1323与工作端1321固定；在不需要使用助力扳手132时，可将手柄1323拆卸下来。从而可减少助力结构13占用的空间。
作为一个可选的方案，如图12所以，助力结构13还包括弹性件133，弹性件133用于驱动工作端1321避让助力销。弹性件133用于驱动工作端1321处于避让的位置。在助力扳手132不使用时，弹性件133推动工作端1321避让开助力销131，在开关单元插入到箱体内时，可避免工作端1321与助力销131之间产生干扰。
作为一个可选的方案，弹性件133可为扭簧、碟簧、压簧等不同的弹性件。
参考图13及图14，图13示出了本申请实施例提供的插接箱的电源模块与壳体的分解示意图。图14示出了风扇与壳体的分解示意图。电源模块70设置在本体的左侧板。在具体装配时，一并参考图9及图13，左侧板213包括第一部分21132和第二部分21131。第一部分21132和第二部分21131之间分别可单独拆卸。当电源模块70损坏时，可将第一部分21132从箱体中拆卸下来，从而不用讲整个插接箱取下即可更换电源模块70。在风扇60出现故障时，可直接将第二部分21131拆卸下来，即可更换风扇60，无需拆分整个插接箱，方便风扇60维修以及更换。
图15所示，图15示出了第一连接端子22的结构示意图。第一连接端子22设置在本体的下侧板2112。第一连接端子22的个数可为多个，具体与主路母线的个数一一对应。示例性的，第一连接端子22采用常见的鸭嘴型连接端子。第一连接端子22的内层导体为铜合金，具有良好的导电性能；第一连接端子22的外层为不锈钢片。通过不锈钢片保护内层的铜合金。另外还提通过不锈钢片提供铜合金夹持主路母线的力。
第二连接端子27设置在箱体的右侧板2111侧。第二铜排延伸到右侧板2111外的第二连接端与第二连接端子27连接。第二连接端子27可采用不同类型的连接端子，如第二连接端子27可采用母线槽连接器，或者其他类型的连接器。
由上述描述可看出，第一连接端子位于箱体的第一表面，第二连接端子位于箱体的第二表面，第一表面和第二表面为相邻的两个表面。上述第一表面为下侧板外露在箱体外的表面；第二表面为右侧板外露在箱体外的表面。在采用上述方式设置时，第一连接端子和第二连接端子位于箱体的不同侧，方便主路母线和支路母线布线。另外，主路母线和支路母线在与插接箱配合时，也不会影响到其他部件的使用，如开关单元的插拔、监控模块的插拔、电源模块或者风扇的拆卸维修等。
作为一个可选的方案，第二连接端子的设置位置还可位于其他的表面，如上侧板、下侧板或者左侧板等其他表面。在具体设置第二连接端子的出线方向时可根据插接箱内其他部件的设置方式合理进行规划，只需要避让开第一连接端子即可。
通过上述描述可看出，本申请实施例提供的插接箱可直接与主路母线和支路母线连接，从而简化了主路母线和支路母线之间的连接结构，方便了数据中心中不同类型母线的连接。另外，还降低了失效点。采用开关单元可插拔的设置方式，在维修开关单元时，无需将整个插接箱取下，降低了维修难度。
本申请实施例还提供了一种数据中心，该数据中心包括密集型母线，密集型母线包括两种类型的母线：主路母线和支路母线。
主路母线沿数据中心延伸，作为主干路提供电能。支路母线作为分支结构，用于给不同的设备进行供电。参考图3所示的插接箱的应用示意图，在主路母线与支路母线连接时，主路母线通过插接箱与支路母线连接，实现主路母线和支路母线的导电连通。
数据中心采用的插接箱为上述任一项的插接箱，每个插接箱的第一连接端子与主路母线连接，第二连接端子与对应的支路母线连接。在采用上述结构时，通过插接箱采用两个连接端子分别与主路母线和支路母线连接，从而简化了主路母线和支路母线之间的连接结构，方便了数据中心中不同类型母线的连接。另外，采用两个连接端子即可实现主路母线和支路母线的连接，降低了失效点。采用开关单元可插拔的设置方式，在维修开关单元时，无需将整个插接箱取下，降低了维修难度。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和 范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
