Embodiment 1

[0080] Figure 21 It is a flow chart of the application method of the communication power supply system according to the embodiment of the present invention. In the method, the monitoring module acquires the phase wire information through the human-computer interaction interface. Such as Figure 21 As shown, the method includes the following steps (step S2102-step S2112):

[0081] In step S2102, the user inputs the grid system information of the grid connected to the AC power distribution module into the monitoring module through the human-computer interaction interface of the monitoring module.

[0082] Step S2104, after the monitoring module obtains the information, it stores the grid system information locally (for example: a non-volatile storage unit).

[0083] As described in the above embodiments, the grid system information acquisition unit in the monitoring module of this embodiment includes a grid system information receiving subunit and a grid system information st...

Embodiment 2

[0093] This embodiment provides an application method of a communication power supply system. In this method, the monitoring module obtains phase wire information through a rectifier, such as Figure 22 The flow chart of the application method of the communication power supply system shown, the method includes the following steps (step S2202-step S2214):

[0094] In step S2202, the user inputs the grid system information of the grid connected to the AC power distribution module into the monitoring module through the human-computer interaction interface of the monitoring module.

[0095] Step S2204, after the monitoring module obtains the information, it stores the grid system information locally (for example: a non-volatile storage unit).

[0096] In step S2206, the rectifier acquires and stores the phase line information of its own phase line.

[0097] The methods of obtaining the phase line information of the phase line where the rectifier is located in this embodiment incl...

Embodiment 3

[0107] The following describes the application process of the communication power system in detail by taking the system connected to the three-phase four-wire low-voltage power grid as an example. Assume that the user selects the low-voltage power grid as the three-phase four-wire system for the first use, and the system is equipped with 9 single-phase rectifiers. The address of the rectifier Numbers 1 to 9 respectively. The connection mode of the AC power distribution unit and the low-voltage power grid is as follows: phase A supplies power to rectifiers 1, 2 and 3; phase B supplies power to rectifiers 4, 5 and 6; phase C supplies power to rectifiers 7, 8 and 9. Figure 23 It is a specific flow chart of the method for acquiring grid system information and phase line information when the system is powered on for the first time according to an embodiment of the present invention, as shown in Figure 23 As shown, the method includes the following steps (step S2302-step S2318): ...

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication power supply system and an application method thereof. Background technique [0002] The communication power supply system is widely used in the global communication field, and mainly obtains satisfactory power supply from the local low-voltage system. Due to historical development, the standards of low-voltage public distribution networks in various countries and regions around the world have not yet been unified. At present, there are three main forms of international common grid operation systems: [0003] The first form is a star connection, such as Figure 1-5 Shown is a schematic diagram of the star connection method of power grid systems in different countries and regions according to related technologies. figure 1 What is shown is a schematic diagram of the star connection method of the three-phase four-wire system. The neutral point in the figure is gr...
