and controlling the internal wiring of the system switching module 200 and the wiring module 300 so as to realize system switching of the system compatible device.
In the embodiment of the present invention, the internal wiring of the standard adapter module 200 and the wiring module 300 is controlled by the connection relationship among the standard compatible circuit 100, the standard adapter module 200, and the wiring module 300, so as to implement the standard switching of the standard compatible device.
In one embodiment of the present invention, referring to fig. 2 and 4, the standard transition module 200 includes a first jack port D1, a second jack port D2, a third jack port D3, a fourth jack port D4, a fifth jack port D5, a sixth jack port D6, a seventh jack port D7, and an eighth jack port D8;

the seventh patch port D7 and the eighth patch port D8 are both connected to the third output terminal S3 of the system-compatible circuit 100;
a first output terminal S1 of the system-compatible circuit 100 is connected to the fifth connection terminal Z5, a second output terminal S2 of the system-compatible circuit 100 is connected to the sixth connection terminal Z6, a third output terminal S3 of the system-compatible circuit 100 is connected to the seventh connection terminal Z7, and a fourth output terminal S4 of the system-compatible circuit 100 is connected to the eighth connection terminal Z8.
In the embodiment of the present invention, the respective connection terminals in the connection module 300 are respectively connected to respective input terminals of the main circuit 10 and respective output terminals of the system-compatible circuit 100, for connecting to external input devices (e.g., an input power supply) and output devices (e.g., a load). For example, the input terminal of the main circuit 10 may be connected to an external first power source, such as a mains supply, through the first connection terminal Z1, the second connection terminal Z2, the third connection terminal Z3, and the fourth connection terminal Z4 of the connection module 300, and the first power source supplies power to the main circuit 10. An input terminal of the main circuit 10 may be an input terminal of the system compatible circuit 100.
Specifically, when the system compatible device operates in a three-in three-out system and the main path 10 operates, the third jack port D3 and the fourth jack port D4 may be connected to the seventh jack port D7 and the eighth jack port D8 in a one-to-one correspondence manner, and the phase difference between the output of the first transforming unit 11 and the output of the second transforming unit 12, the phase difference between the output of the second transforming unit 12 and the output of the third transforming unit 13, and the phase difference between the output of the third transforming unit 13 and the output of the first transforming unit 11 are controlled to be the preset phase difference. Wherein the preset phase difference is 120 degrees. At this time, the first output terminal S1 of the standard compatible circuit 100 is an a-phase output terminal, the second output terminal S2 of the standard compatible circuit 100 is a B-phase output terminal, the third output terminal S3 of the standard compatible circuit 100 is a C-phase output terminal, and the fourth output terminal S4 of the standard compatible circuit 100 is an N-line output terminal.
When the system compatible device operates in a three-input single-output system and the main path 10 operates, the first patch port D1 and the second patch port D2 may be respectively connected to the third patch port D3 and the fourth patch port D4 in a one-to-one correspondence manner, the fifth patch port D5 and the sixth patch port D6 may be respectively connected to the seventh patch port D7 and the eighth patch port D8 in a one-to-one correspondence manner, and the output of the first converting unit 11, the output of the second converting unit 12, and the output of the third converting unit 13 are controlled to be identical, that is, the output of the first converting unit 11, the output of the second converting unit 12, and the output of the third converting unit 13 are controlled to be identical without phase difference. At this time, the current input by the C-phase input terminal C1 (i.e., the third connection terminal Z3) of the main circuit 10 is shunted to the first output terminal S1 of the system-compatible circuit 100 and the second output terminal S2 of the system-compatible circuit 100 through the third patch port D3, the fourth patch port D4, the first patch port D1, and the second patch port D2. Part of the current input by the N-line input terminal N1 (i.e., the fourth connection terminal Z4) of the main circuit 10 is shunted to the third output terminal S3 (i.e., the seventh connection terminal Z7) of the system-compatible circuit 100 through the fifth connection port D5, the sixth connection port D6, the seventh connection port D7, and the eighth connection port D8, while the remaining part of the current flows to the fourth output terminal S4 (i.e., the eighth connection terminal Z8) of the system-compatible circuit 100. At this time, the first output terminal S1 (i.e., the fifth connection terminal Z5) of the system compatible circuit 100 and the second output terminal S2 (i.e., the sixth connection terminal Z6) of the system compatible circuit 100 are both L-line output terminals, and the third output terminal S3 (i.e., the seventh connection terminal Z7) of the system compatible circuit 100 and the fourth output terminal S4 (i.e., the eighth connection terminal Z8) of the system compatible circuit 100 are both N-line output terminals.
Preferably, when the three-in single-out system is adopted, the fifth connection terminal Z5 and the sixth connection terminal Z6 may be shorted together as an L-line output terminal, and the seventh connection terminal Z7 and the eighth connection terminal Z8 may be shorted together as an N-line output terminal, in order to facilitate external connection. In particular, the short circuit can be realized through a short circuit patch.
In the embodiment of the present invention, each of the first transformation unit 11, the second transformation unit 12, and the third transformation unit 13 may include a rectifier subunit and an inverter subunit, and may implement rectification and inversion functions.
As can be seen from the above description, the system-compatible device provided in the embodiment of the present invention can be compatible with a three-in three-out system and a three-in single-out system, and when the three-in three-out system is changed into the three-in single-out system, the current of the live wire can be averagely shunted to the first output terminal S1 and the second output terminal S2 of the system-compatible circuit 100, and the current of the zero wire can be averagely shunted to the third output terminal S3 and the fourth output terminal S4 of the system-compatible circuit 100 by directly adjusting the connection relationship between the plug-in ports, so that the current of each wire can be within the bearable range of the corresponding null switch, and no extra null switch or replacement of the null switch or addition or replacement of an extra wire connecting bar is required, thereby saving the cost. For example, assuming that the currents of the phases a, B and C at the input ends are 60a, the current of the n line is 180A, and the current that can be borne by the air switch corresponding to each line is 100A, when the three-input single-output system is adopted, the current of each output end of the system-compatible circuit 100 is 90A by shunting, and is within the air switch bearable range. Of course, it is also possible to add an N-line output without changing the line connection, but this would increase the cost greatly.
In one embodiment of the present invention, referring to fig. 3 and 4, the system-compatible circuit 100 further includes a static bypass 20;
the connection module 300 further includes a ninth connection terminal Z9, a tenth connection terminal Z10, an eleventh connection terminal Z11, and a twelfth connection terminal Z12;
the static bypass 20 has an input end A2 of a phase a connected to an output end of the first conversion unit 11 and a ninth connection terminal Z9, an input end B2 of a phase B connected to an output end of the second conversion unit 12 and a tenth connection terminal Z10, an input end C2 of a phase C connected to an output end of the third conversion unit 13 and an eleventh connection terminal Z11, and an input end N2 of an N line connected to a fifth connection terminal D5, a sixth connection terminal D6, a fourth output terminal S4 of the system-compatible circuit 100 and a twelfth connection terminal Z12.
In the embodiment of the present invention, each input terminal of the static bypass 20 is connected to an external second power source, such as a commercial power or other power source, through a ninth connection terminal Z9, a tenth connection terminal Z10, an eleventh connection terminal Z11 and a twelfth connection terminal Z12 of the connection module 300. The second power supply supplies the static bypass 20. The second power supply may be the same or different from the first power supply. When the main circuit 10 fails and cannot work, the static bypass 20 can be enabled to work to supply power to the load connected to the output terminal of the system compatible circuit 100.
Specifically, when the system-compatible device operates in a three-in three-out system and the static bypass 20 operates, the third connector port D3 and the fourth connector port D4 may be connected to the seventh connector port D7 and the eighth connector port D8 in a one-to-one correspondence manner, respectively. At this time, the first output terminal S1 of the standard compatible circuit 100 is an a-phase output terminal, the second output terminal S2 of the standard compatible circuit 100 is a B-phase output terminal, the third output terminal S3 of the standard compatible circuit 100 is a C-phase output terminal, and the fourth output terminal S4 of the standard compatible circuit 100 is an N-line output terminal.
When the system compatible device operates in a three-input single-output system and the static bypass 20 operates, the first patch port D1 and the second patch port D2 may be connected to the third patch port D3 and the fourth patch port D4 in a one-to-one correspondence, and the fifth patch port D5 and the sixth patch port D6 may be connected to the seventh patch port D7 and the eighth patch port D8 in a one-to-one correspondence. At this time, the current input by the C-phase input terminal C2 of the static bypass 20 is shunted to the first output terminal S1 of the system-compatible circuit 100 and the second output terminal S2 of the system-compatible circuit 100 through the third plug-in port D3, the fourth plug-in port D4, the first plug-in port D1, and the second plug-in port D2. Part of the current input by the N-line input terminal N2 of the static bypass 20 is shunted to the third output terminal S3 of the system-compatible circuit 100 through the fifth patch port D5, the sixth patch port D6, the seventh patch port D7, and the eighth patch port D8, while the remaining part of the current flows to the fourth output terminal S4 of the system-compatible circuit 100. At this time, the first output terminal S1 of the system-compatible circuit 100 and the second output terminal S2 of the system-compatible circuit 100 are both L-line output terminals, and the third output terminal S3 of the system-compatible circuit 100 and the fourth output terminal S4 of the system-compatible circuit 100 are both N-line output terminals.
As can be seen from the above description, the embodiment of the present invention not only can implement the compatibility between the three-in three-out system and the three-in single-out system of the main path 10, but also can implement the compatibility between the three-in three-out system and the three-in single-out system of the static bypass 20, and in addition, can save the cost.
In one embodiment of the present invention, referring to fig. 3, the standard transition module 200 further includes a ninth jack port D9, a tenth jack port D10, an eleventh jack port D11, a twelfth jack port D12, a thirteenth jack port D13, and a fourteenth jack port D14;
the system-compatible circuit 100 also includes a service bypass 30;
the maintenance bypass 30, a phase input end is respectively connected with a phase input end A2 of the static bypass 20, a first plug-in port D1 and a first output end S1 of the system compatible circuit 100, a phase B input end is respectively connected with a phase B input end B2 of the static bypass 20, a second plug-in port D2 and a second output end S2 of the system compatible circuit 100, a phase C input end is respectively connected with a phase C input end C2 of the static bypass 20, a ninth plug-in port D9 and a tenth plug-in port D10, and an N line input end is respectively connected with an N line input end N2 of the static bypass 20, a fourteenth plug-in port D14 and a fourth output end S4 of the system compatible circuit 100;
the eleventh plug-in port D11 and the twelfth plug-in port D12 are both connected to the third output terminal S3 of the system compatible circuit 100; the N-line input terminal N1 of the main path 10 is connected to the thirteenth patch port D13, and the N-line input terminal N2 of the static bypass 20 is connected to the fourteenth patch port D14.

The service bypass 30 may be used at the time of service. The service bypass 30 may share an input with the static bypass 20.
Specifically, when the system-compatible device operates in a three-in three-out system and the maintenance bypass 30 operates, the ninth socket port D9 and the tenth socket port D10 may be connected to the eleventh socket port D11 and the twelfth socket port D12 in a one-to-one correspondence, respectively.

At this time, since the A, B of the repair bypass 30 and the C phase are shorted together, the currents of the three phases can be shunted to the first output terminal S1 of the system-compatible circuit 100 and the second output terminal S2 of the system-compatible circuit 100. Part of the current input at the N-line input end of the service bypass 30 is shunted to the third output end S3 of the system-compatible circuit 100 through the fourteenth jack port D14, the thirteenth jack port D13, the eleventh jack port D11, and the twelfth jack port D12, while the remaining part of the current flows to the fourth output end S4 of the system-compatible circuit 100.
