具体实施方式
以下描述中，为了说明而不是为了限定，提出了诸如特定***结构、技术之类的具体细节，以便透彻理解本申请实施例。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本申请。在其它情况中，省略对众所周知的***、装置、电路以及方法的详细说明，以免不必要的细节妨碍本申请的描述。
为了说明本发明所述的技术方案，下面通过具体实施例来进行说明。
图1是本发明一实施例提供的制式兼容电路的结构示意图，为了便于说明，仅示出了与本发明实施例相关的部分。如图1所示，该制式兼容电路可以包括：主路10；
主路10包括第一变换单元11、第二变换单元12、第三变换单元13、第一接线端子D1、第二接线端子D2、第三接线端子D3、第四接线端子D4、第五接线端子D5、第六接线端子D6、第七接线端子D7和第八接线端子D8；
主路10，A相输入端A1通过第一变换单元11分别与第一接线端子D1和制式兼容电路的第一输出端S1连接，B相输入端B1通过第二变换单元12分别与第二接线端子D2和制式兼容电路的第二输出端S2连接，C相输入端C1通过第三变换单元13分别与第三接线端子D3和第四接线端子D4连接，N线 输入端N1分别与第五接线端子D5、第六接线端子D6和制式兼容电路的第四输出端S4连接；
第七接线端子D7和第八接线端子D8均与制式兼容电路的第三输出端S3连接。
其中，第一接线端子D1和第二接线端子D2可以位于同一接线排上，例如，位于第一接线排上；第三接线端子D3和第四接线端子D4可以位于同一接线排上，例如，位于第二接线排上；第五接线端子D5和第六接线端子D6可以位于同一接线排上，例如，位于第三接线排上；第七接线端子D7和第八接线端子D8可以位于同一接线排上，例如，位于第四接线排上。至于第一接线排、第二接线排、第三接线排和第四接线排是相同接线排还是不同接线排，可以根据实际需求进行设置，在此不做具体限制。
在本发明实施例中，主路10的输入端可以连接外部第一电源，例如市电，第一电源为主路10供电。主路10的输入端可以作为制式兼容电路的输入端。
具体地，当制式兼容电路以三进三出制式工作，且主路10工作时，可以将第三接线端子D3和第四接线端子D4分别与第七接线端子D7和第八接线端子D8一一对应连接，且控制第一变换单元11的输出与第二变换单元12的输出的相位差、第二变换单元12的输出与第三变换单元13的输出的相位差和第三变换单元13的输出与第一变换单元11的输出的相位差均为预设相位差。其中，预设相位差为120度。此时，制式兼容电路的第一输出端S1为A相输出端，制式兼容电路的第二输出端S2为B相输出端，制式兼容电路的第三输出端S3为C相输出端，制式兼容电路的第四输出端S4为N线输出端。
当制式兼容电路以三进单出制式工作，且主路10工作时，可以将第一接线端子D1和第二接线端子D2分别与第三接线端子D3和第四接线端子D4一一对应连接，将第五接线端子D5和第六接线端子D6分别与第七接线端子D7和第八接线端子D8一一对应连接，且控制第一变换单元11的输出、第二变换单元12的输出和第三变换单元13的输出均一致，即，控制第一变换单元11的输 出、第二变换单元12的输出和第三变换单元13的输出相同，无相位差。此时，主路10的C相输入端C1输入的电流通过第三接线端子D3、第四接线端子D4、第一接线端子D1和第二接线端子D2分流到制式兼容电路的第一输出端S1和制式兼容电路的第二输出端S2。主路10的N线输入端N1输入的部分电流通过第五接线端子D5、第六接线端子D6、第七接线端子D7和第八接线端子D8分流到制式兼容电路的第三输出端S3，同时剩下的部分电流流向制式兼容电路的第四输出端S4。此时，制式兼容电路的第一输出端S1和制式兼容电路的第二输出端S2均为L线输出端，制式兼容电路的第三输出端S3和制式兼容电路的第四输出端S4均为N线输出端。
可选地，当为三进单出制式时，可以将制式兼容电路的第一输出端S1和制式兼容电路的第二输出端S2短接在一起，作为L线输出端，可以将制式兼容电路的第三输出端S3和制式兼容电路的第四输出端S4短接在一起，作为N线输出端。具体可以使用短接片短接。
在本发明实施例中，第一变换单元11、第二变换单元12和第三变换单元13均可以包括整流子单元和逆变子单元，可以实现整流和逆变的功能。
由上述描述可知，本发明实施例提供的制式兼容电路可以兼容三进三出制式和三进单出制式，当由三进三出制式变为三进单出制式时，可以直接通过调整各个接线端子之间的连接关系，将火线的电流平均分流到制式兼容电路的第一输出端S1和第二输出端S2，将零线的电流平均分流到制式兼容电路的第三输出端S3和第四输出端S4，这样可以让每条线的电流在对应空开的可承受范围内，无需增加额外空开或更换空开或增加额外接线排或更换接线排，能够节约成本。例如，假设输入端A相、B相和C相的电流均为60A，N线电流为180A，各个线路对应的空开可承受的电流为100A，当为三进单出制式时，通过分流，制式兼容电路的各个输出端的电流均为90A，在空开可承受范围内。当然，也可以不更改线路连接，直接增加一条N线输出，但是这样会大大增加成本。
在本发明的一个实施例中，参见图2，上述制式兼容电路还包括静态旁路 20；
静态旁路20，A相输入端A2与第一变换单元11的输出端连接，B相输入端B2与第二变换单元12的输出端连接，C相输入端C2与第三变换单元13的输出端连接，N线输入端N2分别与第五接线端子D5、第六接线端子D6和制式兼容电路的第四输出端S4连接。
在本发明实施例中，静态旁路20的输入端可以连接外部第二电源，例如市电或其它电源。第二电源为静态旁路20供电。第二电源与第一电源可以相同也可以不同。当主路10发生故障，无法工作时，可以启用静态旁路20工作，为制式兼容电路输出端连接的负载供电。
具体地，当制式兼容电路以三进三出制式工作，且静态旁路20工作时，可以将第三接线端子D3和第四接线端子D4分别与第七接线端子D7和第八接线端子D8一一对应连接。此时，制式兼容电路的第一输出端S1为A相输出端，制式兼容电路的第二输出端S2为B相输出端，制式兼容电路的第三输出端S3为C相输出端，制式兼容电路的第四输出端S4为N线输出端。
当制式兼容电路以三进单出制式工作，且静态旁路20工作时，可以将第一接线端子D1和第二接线端子D2分别与第三接线端子D3和第四接线端子D4一一对应连接，将第五接线端子D5和第六接线端子D6分别与第七接线端子D7和第八接线端子D8一一对应连接。此时，静态旁路20的C相输入端C2输入的电流通过第三接线端子D3、第四接线端子D4、第一接线端子D1和第二接线端子D2分流到制式兼容电路的第一输出端S1和制式兼容电路的第二输出端S2。静态旁路20的N线输入端N2输入的部分电流通过第五接线端子D5、第六接线端子D6、第七接线端子D7和第八接线端子D8分流到制式兼容电路的第三输出端S3，同时剩下的部分电流流向制式兼容电路的第四输出端S4。此时，制式兼容电路的第一输出端S1和制式兼容电路的第二输出端S2均为L线输出端，制式兼容电路的第三输出端S3和制式兼容电路的第四输出端S4均为N线输出端。
由上述描述可知，本发明实施例不仅可以实现主路10的三进三出制式和三进单出制式的兼容，还可以实现静态旁路20的三进三出制式和三进单出制式的兼容，另外，可以节约成本。
在本发明的一个实施例中，参见图2，制式兼容电路还包括维修旁路30；维修旁路30包括第九接线端子D9、第十接线端子D10、第十一接线端子D11和第十二接线端子D12；主路10还包括与主路10的N线输入端连接的第十三接线端子D13；静态旁路20包括与静态旁路20的N线输入端连接的第十四接线端子D14；
维修旁路30，A相输入端分别与静态旁路20的A相输入端A2、第一接线端子D1和制式兼容电路的第一输出端S1连接，B相输入端分别与静态旁路20的B相输入端B2、第二接线端子D2和制式兼容电路的第二输出端S2连接，C相输入端分别与静态旁路20的C相输入端C2、第九接线端子D9和第十接线端子D10连接，N线输入端分别与静态旁路20的N线输入端N2、第十四接线端子D14和制式兼容电路的第四输出端S4连接；
第十一接线端子D11和第十二接线端子D12均与制式兼容电路的第三输出端S3连接。
其中，第九接线端子D9和第十接线端子D10可以位于同一接线排上，例如，位于第五接线排上；第十一接线端子D11和第十二接线端子D12可以位于同一接线排上，例如，位于第六接线排上；第十三接线端子D13和第十四接线端子D14可以位于同一接线排上，例如，位于第七接线排上。至于第一接线排、第二接线排、第三接线排、第四接线排、第五接线排、第六接线排和第七接线排是相同接线排还是不同接线排，可以根据实际需求进行设置，在此不做具体限制。
维修旁路30可以在维修时使用。维修旁路30可以和静态旁路20共用输入端。
具体地，当制式兼容电路以三进三出制式工作，且维修旁路30工作时，可 以将第九接线端子D9和第十接线端子D10分别与第十一接线端子D11和第十二接线端子D12一一对应连接。此时，制式兼容电路的第一输出端S1为A相输出端，制式兼容电路的第二输出端S2为B相输出端，制式兼容电路的第三输出端S3为C相输出端，制式兼容电路的第四输出端S4为N线输出端。
当制式兼容电路以三进单出制式工作，且维修旁路30工作时，可以将第十四接线端子D14和第十三接线端子D13分别与第十一接线端子D11和第十二接线端子D12一一对应连接，并将静态旁路20的A相输入端A2、静态旁路20的B相输入端B2和静态旁路20的C相输入端C2短接，即将维修旁路30的A相输入端、维修旁路30的B相输入端和维修旁路30的C相输入端短接，并将静态旁路20的N线输入端N2和主路10的N线输入端N1短接。此时，由于维修旁路30的A、B和C相短接在一起，所以，这三相的电流可以分流到制式兼容电路的第一输出端S1和制式兼容电路的第二输出端S2。维修旁路30的N线输入端输入的部分电流通过第十四接线端子D14、第十三接线端子D13、第十一接线端子D11和第十二接线端子D12分流到制式兼容电路的第三输出端S3，同时剩下的部分电流流向制式兼容电路的第四输出端S4。此时，制式兼容电路的第一输出端S1和制式兼容电路的第二输出端S2均为L线输出端，制式兼容电路的第三输出端S3和制式兼容电路的第四输出端S4均为N线输出端。
由上述描述可知，本发明实施例不仅可以实现主路10的三进三出制式和三进单出制式的兼容和静态旁路20的三进三出制式和三进单出制式的兼容，还可以实现维修旁路30的三进三出制式和三进单出制式的兼容；还可以节约成本，节省接线排尺寸等等。
在本发明的一个实施例中，参见图2，维修旁路30还包括第一开关单元31；
维修旁路30，A相输入端通过第一开关单元31分别与第一接线端子D1和制式兼容电路的第一输出端S1连接；B相输入端通过第一开关单元31分别与第二接线端子D2和制式兼容电路的第二输出端S2连接，N线输入端通过第一开关单元31与制式兼容电路的第四输出端S4连接；
第十一接线端子D11和第十二接线端子D12均通过第一开关单元31与制式兼容电路的第三输出端S3连接。
如图2所示，第一开关单元31可以包括四个开关，分别位于维修旁路30的每一条线路上。该四个开关可以位于同一空开上，实现同时闭合，同时断开。当维修旁路30工作时，可以控制第一开关单元31闭合，当维修旁路30不工作时，可以控制第一开关单元31断开。
在本发明的一个实施例中，参见图2，主路10还包括第二开关单元14；
第一变换单元11的输出端通过第二开关单元14分别与第一接线端子D1和制式兼容电路的第一输出端S1连接；第二变换单元12的输出端通过第二开关单元14分别与第二接线端子D2和制式兼容电路的第二输出端S2连接；第三变换单元13的输出端通过第二开关单元14分别与第三接线端子D3和第四接线端子D4连接。
如图2所示，主路10的电流需要经过第二开关单元14才能到达制式兼容电路的输出端，静态旁路20的输出也需要经过第二开关单元14才能到达制式兼容电路的输出端，维修旁路30的输出无需经过第二开关单元14即可到达制式兼容电路的输出端。因此，当主路10或静态旁路20工作时，控制第二开关单元14闭合，当主路10和静态旁路20均不工作时，控制第二开关单元14断开。
其中，第二开关单元14包括三个开关，分别位于主路10的每一条线路上。该三个开关可以位于同一空开上，实现同时闭合，同时断开。
在本发明的一个实施例中，制式兼容电路还包括控制模块；
控制模块分别与第一变换单元11、第二变换单元12和第三变换单元13连接。
在本发明实施例中，控制模块可以控制第一变换单元11、第二变换单元12和第三变换单元13以什么形式输出，以适应三进三出制式或三进单出制式。具体地，当以三进三出制式工作时，控制模块控制第一变换单元11的输出与第二 变换单元12的输出的相位差、第二变换单元12的输出与第三变换单元13的输出的相位差和第三变换单元13的输出与第一变换单元11的输出的相位差均为预设相位差；当以三进单出制式工作时，控制模块控制第一变换单元11的输出、第二变换单元12的输出和第三变换单元13的输出均一致。
可选地，控制模块还可以和第一开关单元31和第二开关单元14连接，用于控制第一开关单元31的闭合或断开，控制第二开关单元14的闭合或断开。
可选地，控制模块还可以和各个接线端子连接，用于控制各个接线端子之间的连接关系。
可选地，各个接线端子的连接关系也可以通过人工来进行控制或更改。
