[0035] First Embodiment

[0036] Referring to Figure 1 , Figure 1 Fig. 1 shows a structural block diagram of a communication power supply system provided in the first embodiment of the present application. The communication power supply system 200 comprises an AC power distribution module 201, a rectifier module 203, a DC power distribution module 10 and a monitoring module 207.

[0037] ​​The AC power distribution module 201 is configured to provide AC power. The AC power distribution module 201 comprises an AC power distribution unit 2011 and a lightning protection unit 2013. The lightning protection unit 2011 is configured to perform lightning protection detection on the AC power distribution unit 2011 and provide the detection result to the monitoring module 207.

[0038] The rectifier module 203 is connected with the AC power distribution unit 2011 of the AC power distribution module 201 and is configured to convert AC power into DC power and provide the DC power to the DC power distribution module 10. The rectifier module 203 comprises a plurality of rectifier units 2031 and a connector 2033 connected with the plurality of rectifier units 2031.

[0039] The DC power distribution module 10 comprises a power busbar 11, an important load output module 13, a secondary load output module 14, a battery module 15 and a signal driving and collecting module 17. The power busbar 11 is connected with the connector 2033 of the rectifier module 203. The important load output module 13, the secondary load output module 14 and the battery module 15 each comprise a circuit breaker 19.

[0040] The important load output module 13 further comprises an important load 131 connected with the circuit breaker 19 of the important load output module 13. The secondary load output module 14 further comprises a secondary load 141 connected with the circuit breaker 19 of the secondary load output module 14. The battery module 15 further comprises a battery 151 connected with the circuit breaker 19 of the battery module 15. The circuit breaker 19 of the important load output module 13, the circuit breaker 19 of the secondary load output module 14 and the circuit breaker 19 of the battery module 15 are all connected with the power busbar 11. The circuit breakers 19 in all functional (important load 131, secondary load 141, battery 151 access) areas share the same power busbar 11, which is conducive to simplifying the structure of the DC power distribution module 10. The rectifier module 203 is configured to supply power to the important load 131, the secondary load 141 and the battery 151; the battery 151 is configured to supply power to the important load 131 and the secondary load 141 when the rectifier module 203 fails to supply power.

[0041] More specifically, the important load output module 13 comprises M important load branches 130, each of which is provided with a circuit breaker 19 and an important load 131, and M is an integer greater than or equal to 1; the secondary load output module 14 comprises N secondary load branches 140, each of which comprises a circuit breaker 19 and a secondary load 141, and N is an integer greater than or equal to 1; the battery module 15 comprises P battery branches 150, each of which is provided with a circuit breaker 19 and a battery 151, and P is an integer greater than or equal to 1.

[0042] The signal-driven acquisition module 17 is connected with the circuit breakers 19 of the important load output module 13, the circuit breakers 19 of the secondary load output module 14, and the circuit breakers 19 of the battery module 15, and is used to acquire circuit breaker signals of the circuit breakers 19. The circuit breaker signals include closing signals, opening signals, circuit breaker address signals, circuit breaker current signals, circuit breaker voltage signals, and fault tripping state signals.

[0043] The monitoring module 207 is used to control and monitor the circuit breakers 19 according to the circuit breaker signals acquired by the signal-driven acquisition module 17, so as to improve the intelligence and reliability of the communication power supply system 200. For example, when the monitoring module 207 obtains an instruction to disconnect a circuit breaker 19 at a certain address, the monitoring module 207 identifies the circuit breaker 19 at the corresponding address through the acquired circuit breaker signals and controls the disconnection. For another example, the monitoring module 207 can monitor the state of the circuit breakers 19 through the acquired circuit breaker current signals to determine whether each circuit breaker 19 can effectively perform the conduction and disconnection of the circuit, so as to improve the safety and reliability of the communication power supply system 200. That is, the signal-driven acquisition module 17 acquires the circuit breaker signals, and the functions not only include detecting the state of the circuit breakers, but also include controlling the disconnection and closure of the circuit breakers, detecting the circuit breaker current, acquiring the circuit breaker address, and identifying the circuit breaker, etc. The monitoring module 207 can control and monitor the circuit breakers according to the circuit breaker signals acquired by the signal-driven acquisition module 17.

[0044] The communication power supply system 200 of the first embodiment of the present application takes power through the power busbar 11, and the monitoring module 207 controls the conduction / disconnection (i.e., power-on and power-off) of the circuit breakers 19 of the important load output module 13, the secondary load output module 14, and the battery module 15 and monitors the state of the circuit breakers through the circuit breaker signals of the circuit breakers 19 acquired by the signal-driven acquisition module 17. Since the contactors are not used for power-on and power-off and the shunt is not used for shunting in the DC power distribution module 10, there is no functional distinction between the important load, the secondary load, and the battery in terms of physical hardware, so the flexibility of the layout of the DC power distribution module 10 is improved.

[0045] The monitoring module 207 is also used to monitor the voltage of the battery 151 to control the power supply of the battery to the important load 131 and the secondary load 141. When the battery 151 supplies power and the voltage of the battery 151 is less than a preset maximum threshold voltage, the power supply circuit for supplying power from the battery 151 to the secondary load 141 is disconnected. When the battery 151 supplies power and the voltage of the battery 151 is less than a preset minimum threshold voltage, the power supply circuit for supplying power from the battery 151 to the important load 131 and the secondary load 141 is disconnected.

[0046] Figure 1The working principle of the communication power supply system 200 is as follows: normally, the rectifier module 203 supplies power to the important load 131, the secondary load 141 and the battery 151; when the rectifier module 203 fails to supply power, the battery 151 supplies power to the important load 131 and the secondary load 141; when the voltage of the battery 151 is greater than or equal to the preset maximum threshold voltage and greater than or equal to the preset minimum threshold voltage, the voltage of the battery 151 can be used to simultaneously operate the important load 131 and the secondary load 141; when the voltage of the battery 151 is less than the preset maximum threshold voltage and greater than or equal to the preset minimum threshold voltage, the voltage of the battery 151 is insufficient to simultaneously operate the important load 131 and the secondary load 141, but can be used to operate the important load 131, therefore, the monitoring module 207 controls the disconnection of the circuit breaker 19 on the secondary load output module 14, so that the secondary load output module 14 is powered off, thereby ensuring the normal operation of the important load 131.

[0047] It can be understood that the number of the circuit breaker 19 in the important load output module 13 is not limited, for example, the important load output module 13 can also include one circuit breaker 19 and M important loads 131, and the monitoring module 207 controls the M important loads 131 through the one circuit breaker 19; the number of the circuit breaker 19 in the secondary load output module 14 is not limited, the secondary load output module 14 can also include one circuit breaker 19 and N secondary loads 141, and the monitoring module 207 controls the N secondary loads 141 through the one circuit breaker 19; the number of the circuit breaker 19 in the battery module 15 is not limited, the battery module 15 can also include one circuit breaker 19 and P batteries 151, and the monitoring module 207 controls the P batteries 151 through the one circuit breaker 19.

[0048] Please refer to Figure 2 and Figure 3 , Figure 2 the perspective assembly schematic diagram of the DC power distribution module provided for the first embodiment of the present application, Figure 3 for Figure 2 the perspective assembly schematic diagram of the circuit breaker and the power busbar and the signal driving and collecting module. Figure 3 Only one circuit breaker 19 is shown to be assembled with the power busbar 11 and the signal driving and collecting module 17, and the remaining circuit breakers 19 are hidden. The circuit breaker 19 includes a first slot 191, a plug-in slot 193 and a second slot 195 which are arranged at intervals along the Z direction, wherein the plug-in slot 193 is located between the first slot 191 and the second slot 195. The first slot 191, the plug-in slot 193 and the second slot 195 are all through slots extending along the Y direction.

[0049] The power busbar 11 includes a positive power busbar 111 and a negative power busbar 113. The positive power busbar 111 is plugged into the first plug slot 191 and connected with the circuit breaker 19, the negative power busbar 113 is plugged into the second plug slot 195 and connected with the circuit breaker 19, the signal driving and collecting module 17 is plugged into the plug slot 193 and connected with the circuit breaker 19, and the positive power busbar 111, the negative power busbar 113 and the signal driving and collecting module 17 are stacked along the Z direction, wherein the signal driving and collecting module 17 is located between the positive power busbar 111 and the negative power busbar 113.

[0050] Please refer to Figure 4 , Figure 4 is a structural schematic diagram of a direct current power distribution module in an application scenario, and the signal driving and collecting module 17 includes a plurality of signal collecting boards 171. The plurality of signal collecting boards 171 are arranged side by side. Figure 4 Only two signal collecting boards 171 are exemplarily shown.

[0051] The signal collecting board 171 includes a plurality of first signal units 1711 and a plurality of guide grooves 1713. The plurality of first signal units 1711 are sequentially arranged along the Y direction, and one guide groove 1713 is arranged between each adjacent two first signal units 1711. That is, the guide groove 1713 is a guide structure for guiding the signal collecting board 171 to be plugged into the plug slot 173, facilitating the assembly of the signal collecting board 171 and the circuit breaker 19. In the embodiment, the signal collecting board 171 is substantially comb-shaped, the first signal unit 1711 is substantially tooth-shaped structure, and the guide groove 1713 is a groove structure arranged between the adjacent two first signal units 1711, Figure 4 In the embodiment, each signal collecting board 171 includes 14 first signal units 1711.

[0052] The widths of the plurality of first signal units 1711 are the same, and the widths of the plurality of guide grooves 1713 are the same, that is, the plurality of first signal units 1711 are arranged on the signal collecting board 171 at equal intervals, so as to facilitate the plugging of the signal collecting board 171 into the circuit breaker 19 for limiting and preventing errors. It can be understood that the plurality of first signal units 1711 are not limited to be arranged at equal intervals, and the widths of the plurality of guide grooves 1713 are not limited to be the same.

[0053] The connection area 1701 of the signal acquisition board 171, when connected to each circuit breaker 19, is provided with an integer number of first signal units 1711. In other words, each circuit breaker 19 is provided with an integer number of first signal units 1711 corresponding to the signal drive acquisition module 17 in the Y direction, for example, 1, 2, etc. The connection area 1701 of the signal drive acquisition board 171, which is connected to the plug slot 193 of each circuit breaker 19, is provided with an integer number of first signal units 1711, that is, the plug slot 193 is provided with an integer number of first signal units 1711 corresponding to the Y direction. A second signal unit 194 is provided in the plug slot 193 of the circuit breaker 19. The second signal unit 194 is connected to a first signal unit 1711 corresponding to the position of the signal acquisition board 1711, so that the signal acquisition board 171 can acquire the circuit breaker signal of the circuit breaker 19 and feed it back to the monitoring module 207. The first signal unit 1711 is a connection terminal, and the second signal unit 194 is a connection interface, or other structures that can realize signal transmission between the two.

[0054] In this embodiment, the circuit breaker 19 includes a plurality of first circuit breakers 196 and a plurality of second circuit breakers 197. The first circuit breakers 196 and the second circuit breakers 197 have different widths. The first circuit breaker 196 is a 125A circuit breaker and the second circuit breaker 197 is a 63A circuit breaker.

[0055] Let the width of the first circuit breaker 196 be W1, and the width of the second circuit breaker 197 be W2, where W1:W2 = 1.5:1. The connection area 1701 between the signal acquisition board 171 and the first circuit breaker 196 is provided with three first signal units 1711 (e.g., ...). Figure 4 As shown in the diagram (numbered 10-12), the first circuit breaker 196 is provided with three first signal units 1711 along the Y direction; the connection area 1701 where the signal acquisition board 171 connects to the second circuit breaker 197 is provided with two first signal units 1711 (e.g., ...). Figure 4 As shown in the figure (numbered 4-5), the second circuit breaker 197 is configured with two first signal units 1711 along the Y direction.

[0056] Since the tooth width of multiple first signal units 1711 is consistent, the width of multiple guide slots 1713 is consistent, and the width of the first circuit breaker 196 and the width of the second circuit breaker 197 in the Y direction correspond to an integer number of first signal units 1711, the first circuit breaker 196 and the second circuit breaker 197 can be installed arbitrarily with the signal acquisition board 171 without restriction. That is, the circuit breakers 19 on the important load output module 13, the secondary load output module 14, and the battery module 15 can be randomly inserted with the signal acquisition board 171 according to their own arrangement, which improves the freedom of connecting the important load 131, the secondary load 141, and the battery 151 to the communication power system 200.

[0057] It can be understood that W1:W2 is not limited to 1.5:1, and can also be other values, for example, 2:1, 1:1, 2:1, etc.

[0058] In another application scenario, referring to Figure 5 , the signal acquisition board 171 is assembled with three circuit breakers 19 of different widths, including a first circuit breaker 196, a second circuit breaker 197, and a third circuit breaker 198. The width of the first circuit breaker 196 is W1, the width of the second circuit breaker 197 is W2, and the width of the third circuit breaker 198 is W3. W1:W2:W3=1:1.5:2, in other words, the connection area 1701 of the signal acquisition board 171 connected with the first circuit breaker 196 is provided with two first signal units 1711, the connection area 1701 of the signal acquisition board 171 connected with the second circuit breaker 197 is provided with three first signal units 1711, and the connection area 1701 of the signal acquisition board 171 connected with the third circuit breaker 198 is provided with four first signal units 171.

[0059] In yet another application scenario, referring to Figure 6 , the signal acquisition board 171 is assembled with two circuit breakers 19 of different widths, including a first circuit breaker 196 and a second circuit breaker 197. The width of the first circuit breaker 196 is W1, and the width of the second circuit breaker 197 is W2. W1:W2=0.5:1, that is, the width W1 of the first circuit breaker 196 is approximately the same as the width of one first signal unit 1711. The connection area 1701 of the signal acquisition board 171 connected with the first circuit breaker 196 is provided with one first signal unit 1711, and the connection area 1701 of the signal acquisition board 171 connected with the second circuit breaker 197 is provided with two first signal units 171.

[0060] It can be understood that the structure in the direct current power distribution module in the embodiment can also be applied to the alternating current power distribution module. In an embodiment, a power distribution module includes a power busbar, an important load output module, a secondary load output module, a battery module, and a signal driving and acquisition module.

The connection area of the signal driving and acquisition module connected with each circuit breaker is provided with an integer number of first signal units. Each circuit breaker is provided with one second signal unit. The second signal unit is in butt joint with one of the first signal units.
