[0001] This application relates to the technical field of power supply wiring, and more specifically, to a power supply wiring circuit and its power consumption system. Background Art

[0002] In the existing power supply system, when one power supply supplies power to multiple devices, generally, the power supply single wire 1 is connected to device 1, and the single wire 2 is connected to device 2 after being paralleled, and so on, until the last device.

[0003] However, once a failure occurs in the above traditional method, for example, if single wire 3 is the wiring between electrical device 2 and electrical device 3, and a failure occurs in it, the electrical devices after electrical device 2 will not work properly. Therefore, the traditional power supply wiring method of one power supply and multiple devices has the problem of low power supply reliability. Summary of the Utility Model

The power supply wiring circuit includes a power supply, a first power supply wire, and a second power supply wire. The power supply is electrically connected to a first electrical device through the first power supply wire, and the power supply is electrically connected to a second electrical device through the second power supply wire. Among them, the first electrical device is the electrical device at the starting position of the series connection of the multiple electrical devices connected in series in sequence by the power supply wire, and the second electrical device is the electrical device at the ending position of the series connection of the multiple electrical devices connected in series in sequence by the power supply wire.

[0006] In the power supply wiring circuit designed above, in this solution, the power supply is connected to the electrical device at the starting position of the series connection of the multiple electrical devices connected in series in sequence by the power supply wire through the first power supply wire, and the power supply is connected to the electrical device at the ending position of the series connection of the multiple electrical devices connected in series in sequence by the power supply wire through the second power supply wire. In this way, when a break occurs somewhere in the multiple electrical devices connected in series in sequence by the power supply wire (for example, a certain electrical device fails or the power supply wire between two electrical devices fails), the power supply can be transmitted in reverse to the remaining electrical devices through the second power supply wire and the electrical device at the ending position of the series connection, thereby improving the power supply reliability of the power supply wiring method of one power supply and multiple devices.

[0007] In an alternative embodiment of the first aspect, the first power supply wire includes a first sub-power supply wire and a second sub-power supply wire. The positive pole of the power supply is electrically connected to the positive terminal of the first electrical device through the first sub-power supply wire, and the negative pole of the power supply is electrically connected to the negative terminal of the first electrical device through the second sub-power supply wire.

[0008] In an alternative embodiment of the first aspect, the second power supply line includes a third sub-power supply line and a fourth sub-power supply line.

[0010] In the above embodiment, the power supply on / off switching between the power supply and multiple electrical devices can be realized by controlling the opening and closing of the first switch, thereby improving the power supply controllability of the power supply connection circuit.

[0011] In an alternative embodiment of the first aspect, the power supply connection circuit further includes a circuit breaker. The first power supply line is electrically connected to the first switch through the circuit breaker.

[0012] In the above embodiment, in the case of a fault in multiple electrical devices, the power supply line can be protected by the circuit breaker in this solution.

[0013] In an alternative embodiment of the first aspect, the power supply connection circuit further includes a second switch. The second power supply line is electrically connected to the second electrical device through the second switch.

[0014] In the above embodiment, by controlling the opening and closing of the second switch, the power supply direction between the power supply and multiple electrical devices can be switched from a single power supply direction to the aforementioned dual-path power supply direction, thereby improving the power supply reliability.

[0015] In an alternative embodiment of the first aspect, both the first switch and the second switch are relays.

[0016] In an alternative embodiment of the first aspect, the power supply connection circuit further includes a plurality of third switches. The third switches are arranged between the power supply connection lines of every two serially connected electrical devices.

[0017] In an alternative embodiment of the first aspect, the third switch is a disconnecting switch.

[0018] In the above embodiment, the power supply on / off between multiple electrical devices connected in series to the power supply line can be controlled by the third switch, thereby improving the power supply controllability of the power supply connection circuit.

[0019] Second aspect, the present utility model provides a power consumption system, which includes the power supply wiring circuit described in any of the optional implementation manners of the first aspect and multiple electrical devices. The multiple electrical devices are connected in series in sequence through a power supply line. The power supply is electrically connected to the first electrical device through a first power supply line, and the power supply is electrically connected to the second electrical device through a second power supply line. Among them, the first electrical device is the electrical device at the starting position of the series connection of the multiple electrical devices connected in series through the power supply line, and the second electrical device is the electrical device at the ending position of the series connection of the multiple electrical devices connected in series through the power supply line.

[0020] For the power consumption system designed above, since the power consumption system includes the aforementioned power supply wiring circuit, therefore, in the designed power consumption system, the power supply is connected to the electrical device at the starting position of the series connection of the multiple electrical devices connected in series through the power supply line by the first power supply line, and the power supply is connected to the electrical device at the ending position of the series connection of the multiple electrical devices connected in series through the power supply line by the second power supply line. In this way, when there is a break in a certain place among the multiple electrical devices connected in series through the power supply line (for example, a certain electrical device fails or the power supply line between two electrical devices fails), the power supply can be reversely transmitted to the remaining electrical devices through the second power supply line and the electrical device at the ending position of the series connection, thereby improving the power supply reliability of the power supply wiring method for one power supply and multiple devices.

The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0038] In the existing power supply system, when one power supply supplies power to multiple devices, generally, the power supply single wire 1 is connected to device 1, and the single wire 2 is connected to device 2 after being paralleled, and so on, until the last device.

[0039] However, once a failure occurs in the above traditional method, for example, the single wire 3 is the wiring between the electrical device 2 and the electrical device 3. In the case of its failure, the electrical devices after the electrical device 2 will not be able to work properly. Therefore, the traditional wiring method of one power supply and multiple devices has the problem of low power supply reliability.

[0040] Based on the above problems, the present application designs a power supply wiring circuit and its power consumption system. The power supply is connected to the power consumption device at the starting position in series among a plurality of power consumption devices connected in series by the first power supply line and the power supply line in sequence. The power supply is connected to the power consumption device at the ending position in series among a plurality of power consumption devices connected in series by the second power supply line and the power supply line in sequence. In this way, when there is a break in a certain place among a plurality of power consumption devices connected in series by the power supply line (for example, a certain power consumption device fails or the power supply line between two power consumption devices fails), the power supply can be reversely transmitted to the remaining power consumption devices through the second power supply line and the power consumption device at the ending position in series, thereby improving the power supply reliability of the power supply wiring method for one power supply and multiple devices.

[0041] Based on the above idea, the present application first provides a power supply wiring circuit, as Figure 1 shown. This power supply wiring circuit is used to supply power to a plurality of power consumption devices connected in series in sequence. The plurality of power consumption devices connected in series in sequence can be connected in series through the power supply line. Specifically, this power supply wiring circuit includes a power supply 10, a first power supply line 11, and a second power supply line 12. The power supply 10 is electrically connected to the first power consumption device A1 through the first power supply line 11, and the power supply 10 is electrically connected to the second power consumption device An through the second power supply line 12. Among them, the first power consumption device A1 is the power consumption device at the starting position in series among a plurality of power consumption devices connected in series in sequence, and the second power consumption device An is the power consumption device at the ending position in series among a plurality of power consumption devices connected in series in sequence. For example, there are n power consumption devices. In this case, the plurality of power consumption devices connected in series in sequence can be A1, A2, A3 to An respectively.

[0042] In the power supply wiring circuit designed above, under normal circumstances, the power supply 10 supplies power to the first power consumption device A1 through the first power supply line 11, and the power consumption device A2 is supplied power through the power supply line connected in series with the first power consumption device A1, and so on. The second power consumption device An is supplied power through the power supply line connected in series with the power consumption device An - 1.

[0043] When a certain electrical equipment fails, this solution can use the power supply to reverse transmit to the remaining electrical equipment through the second power supply line and the electrical equipment in the series termination position, thereby improving the power supply reliability of the power supply connection method for one power supply and multiple devices. For example, when the power supply line between electrical equipment A3 and electrical equipment A2 fails, the power supply direction becomes two paths. The first branch: The power supply 10 still supplies power to the first electrical equipment A1 through the first power supply line 11, and the electrical equipment A2 is supplied power through the power supply line in series with the first electrical equipment A1. Since the power supply line between electrical equipment A3 and electrical equipment A2 fails, the electrical equipment A3 cannot be supplied power through the power supply line between it and the electrical equipment A2. The second branch: Since the power supply 10 is connected to the second electrical equipment An through the second power supply line 12, therefore, the second electrical equipment An can be supplied power through the second power supply line 12. The power supply line connection between the second electrical equipment An and the electrical equipment An - 1 is not faulty. Therefore, the electrical equipment An - 1 can be supplied power through the power supply equipment connected to the second electrical equipment An. And so on, the electrical equipment 4 can be supplied power through the power supply equipment connected to the electrical equipment 5, and the electrical equipment 3 can be supplied power through the power supply equipment connected to the electrical equipment 4. Thus, when the power supply line between the electrical equipment A3 and the electrical equipment A2 fails, multiple serially connected electrical equipment can all be powered, improving the power supply reliability of the power supply connection method for one power supply and multiple devices.

[0044] For the power supply connection circuit designed above, in this solution, the power supply is connected to the electrical equipment in the series starting position among multiple serially connected electrical equipment through the first power supply line, and the power supply is connected to the electrical equipment in the series termination position among multiple serially connected electrical equipment through the second power supply line. In this way, when there is an open circuit somewhere among multiple serially connected electrical equipment (such as a certain electrical equipment fails or the power supply line between two electrical equipment fails), the power supply can reverse transmit to the remaining electrical equipment through the second power supply line and the electrical equipment in the series termination position, thereby improving the power supply reliability of the power supply connection method for one power supply and multiple devices.

[0045] In an alternative implementation of this embodiment, such as Figure 2As shown, the power supply 10 may include a positive electrode and a negative electrode. The first power supply line 11 may include a first power supply sub-line 111 and a second power supply sub-line 112. The second power supply line 12 may include a third power supply sub-line 121 and a fourth power supply sub-line 122. In this case, the positive electrode of the power supply 10 is electrically connected to the positive terminal of the first electrical device A1 through the first power supply sub-line 111, and the negative electrode of the power supply 10 is electrically connected to the negative terminal of the first electrical device A1 through the second power supply sub-line 112; the positive electrode of the power supply 10 is electrically connected to the positive terminal of the second electrical device An through the third power supply sub-line 121, and the negative electrode of the power supply 10 is electrically connected to the negative terminal of the second electrical device An through the fourth power supply sub-line 122.

[0046] In an alternative embodiment of this embodiment, as Figure 3 shown, the power supply connection circuit designed in this solution may further include a first switch 20. The first power supply line 11 is electrically connected to the first electrical device A1 through the first switch 20.

[0047] In the above-described embodiment, the power supply on / off switching between the power supply 10 and multiple electrical devices can be achieved by controlling the opening and closing of the first switch 20, thereby improving the power supply controllability of the power supply connection circuit.

[0048] In an alternative embodiment of this embodiment, as Figure 4 shown, the power supply connection circuit designed in this solution may further include a circuit breaker 30. The circuit breaker 30 may be disposed between the power supply 10 and the first switch 20. In this way, in the case of a failure in multiple electrical devices, the power supply line can be protected by the circuit breaker 30 in this solution.

[0049] In an alternative embodiment of this embodiment, as Figure 5 shown, the power supply connection circuit designed in this solution may further include a second switch 40. The second power supply line 12 is connected to the second electrical device An through the second switch 40.

[0050] In the above-described embodiment, the power supply line switching between the power supply 10 and multiple electrical devices can be achieved by controlling the opening and closing of the second switch 40. Specifically, for example, the second switch 40 may be in an open state under normal circumstances. In the case of an open circuit somewhere in a series of multiple electrical devices (such as a failure of a certain electrical device or a failure of the power supply line between two electrical devices), the second switch 40 is controlled to close in this solution, so that the power supply direction between the power supply 10 and multiple electrical devices is switched from a single power supply direction to the aforementioned dual-path power supply direction, thereby improving the power supply reliability.

[0051] As a possible implementation, multiple sensors, such as current sensors or voltage sensors, can be set in the power supply wiring circuit. The power supply situation of the circuit is identified by the multiple sensors set. When an open circuit occurs at a certain place in the multiple electrical devices connected in series in sequence (for example, a certain electrical device fails or the power supply line between two electrical devices fails), this solution can automatically control the second switch 40 to close, thereby realizing the automatic switching of the power supply direction, improving the switching efficiency of the power supply wiring circuit, and further improving the reliability of the power supply wiring circuit designed by this solution.

[0052] In an alternative implementation of this embodiment, as Figure 6 shown, the power supply wiring circuit designed by this solution further includes multiple third switches 50. The third switches are arranged between the power supply connection lines of every two serially connected electrical devices, so as to control the power supply on and off of every two serially connected electrical devices.

[0053] Among them, the first switch 20, the second switch 40, and the third switch 50 described above can all be any current controllable switch, for example, a relay, a disconnect switch, and so on.

[0054] This application also provides an electrical system, as Figure 7 shown. The electrical system includes the power supply wiring circuit 1 of any one of the alternative implementations described above and multiple electrical devices A. The multiple electrical devices A are connected in series in sequence through a power supply line. The power supply 10 is electrically connected to the first electrical device A1 through the first power supply line 11, and the power supply 10 is electrically connected to the second electrical device An through the second power supply line 12. Among them, the first electrical device A1 is the electrical device at the starting position of the multiple serially connected electrical devices, and the second electrical device An is the electrical device at the ending position of the multiple serially connected electrical devices.

[0055] For the electrical system designed above, since the electrical system includes the aforementioned power supply wiring circuit, the designed electrical system connects the power supply to the electrical device at the starting position of the multiple serially connected electrical devices through the first power supply line, and connects the power supply to the electrical device at the ending position of the multiple serially connected electrical devices through the second power supply line. In this way, when an open circuit occurs at a certain place in the multiple serially connected electrical devices (for example, a certain electrical device fails or the power supply line between two electrical devices fails), the power supply can be transmitted in the reverse direction to the remaining electrical devices through the second power supply line and the electrical device at the ending position of the series connection, thereby improving the power supply reliability of the power supply wiring method of one power supply and multiple devices.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present application, and they should all be covered by the scope of the claims and the specification of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
