The invention provides a power supply system for an indoor communication data machine room.
Referring to fig. 1, the power supply system of the indoor communication data center of the present embodiment includes two methanol-water reformed hydrogen fuel cell generators, i.e. a first methanol-water reformed hydrogen fuel cell generator 26 and a second methanol-water reformed hydrogen fuel cell generator 20, which are identical in structural arrangement, for example, the first methanol-water reformed hydrogen fuel cell generator has a first heat dissipation pipe 11 for dissipating heat and is used for discharging purge gas (H) from the first heat dissipation pipe 112O、CO2And air), a first stack water discharge pipeline 13 for discharging the generated water vapor or water, and correspondingly, the second methanol-water reforming hydrogen fuel cell power generator is provided with a first heat dissipation pipeline 16, a second stack water discharge pipeline 17, and a second stack water discharge pipeline 18. The two methanol-water reformed hydrogen fuel cell generators are connected through a communication line 14 to realize data exchange, the anodes of the two methanol-water reformed hydrogen fuel cell generators are connected with the anode of a machine room backflow row through a first isolation diode 25 and a second isolation diode 15, and the two methanol-water reformed hydrogen fuel cell generators are connected with the anode of the machine room backflow row through a first isolation diode 25 and a second isolation diode 15The cathode of the methanol-water reformed hydrogen fuel cell generator is connected to the anode of the machine room return line through a first power supply cable 24 and a first power supply cable 27. In addition, the two methanol-water reforming hydrogen fuel cell generators are also simultaneously connected with a monitoring module 19 for monitoring the electrification condition of the commercial power 220 VAC. The positive pole of computer lab busbar still links to each other with lithium iron phosphate battery 23's positive pole, and the negative pole of computer lab busbar still links to each other with lithium iron phosphate battery 23's negative pole, and is that link to each other through third confession transmission cable 28 between computer lab busbar and the lithium iron phosphate battery 23 promptly. The positive electrode of the lithium iron phosphate battery 23 is connected with the positive electrode of the grid-connectable inverter 22 through the direct current contactor 21, and the negative electrode of the lithium iron phosphate battery 23 is directly connected with the negative electrode of the grid-connectable inverter 22.
In addition, the machine room bus bar of the indoor communication data machine room power supply system of the embodiment is a direct current bus bar provided in the machine room, and the type of the grid-connectable inverter 22 is 48VDC to 380 VAC.
The working principle of the indoor communication data machine room power supply system of the embodiment is as follows:
the indoor communication data computer room power supply system of the embodiment mainly adopts the commercial power of 220VAC to supply power daily, when the commercial power has a sudden power failure, the monitoring module 19 receives a power-off signal, and needs to immediately start two methanol-water reforming hydrogen fuel cell generators to generate power, and needs to wait for 1-2 minutes between the power failure of the commercial power and the formal power supply of the generators, so that the generators can stably output power to the power supply device. In the conversion time of 1-2 minutes, the electric power required by the internal equipment of the machine room is directly supplied by the lithium iron phosphate battery 23, so that the power supply of the indoor communication data machine room power supply system can not be flashed when the power supply is switched off from the mains supply to the generator to stabilize the power generation process, and the system can realize quick response and seamless butt joint.
In this embodiment, the internal structure of the communication data machine room is usually a relatively closed environment, and the indoor temperature is maintained within a relatively stable temperature range by means of air-conditioning refrigeration in daily use. If the commercial power stops supplying suddenly, after the two methanol-water reformed hydrogen fuel cell generators are started and stably operated, the temperature inside the communication data computer room may continuously rise, so that fresh air needs to be continuously supplied into the communication data computer room to cool and maintain the normal operation of the generators, at this time, the air inlet fan 10 arranged on the surface of the computer room needs to be started to supply fresh air to the inside of the computer room, and the temporary electric energy of the air inlet fan needs to be supplied through the lithium iron phosphate battery 23 electrically connected with the air inlet fan. If the ambient temperature is higher than 30 ℃ and when the methanol water reforming hydrogen fuel cell generator starts to operate, the grid-connectable inverter 22 starts to supply the AC380V power to the air conditioner by switching on the dc contactor 21, and the air conditioner temperature is generally set at about 25 ℃, then the air intake fan 10 is turned off to cool and supply fresh air by the air conditioner.
If the commercial power is electrified again, the methanol-water reformed hydrogen fuel cell generator receives corresponding information feedback to stop supplying power and enters a standby mode, correspondingly, the direct current contactor 21 is disconnected, and the air conditioner is supplied with power again by the commercial power.
In addition, when the methanol-water reformed hydrogen fuel cell generator of the present embodiment is operated, the generated steam or water is discharged to the outdoor sewer through the first stack water discharge pipe 13 and the second stack water discharge pipe 18, respectively, and the generated purge gas (H) is generated2O、CO2Air) is discharged to the outside through the first purge gas exhaust duct 12 and the second purge gas exhaust duct 17, respectively, and the hot gas generated by the hydrogen fuel cell 32 in the generator is discharged to the outside through the first heat dissipation duct 11 and the second heat dissipation duct 16, respectively.
The first isolation diode 25 and the second isolation diode 15 of the present embodiment play an isolation role, and when the generator does not generate electricity, the current on the direct current bus bar of the machine room does not flow back to the generator. The lithium iron phosphate battery 23 is adaptively configured according to the requirements of communication operators, the power of the grid-connected inverter 22 can be configured according to actual needs, and the communication line 14 ensures the communication coordination operation between the two methanol water reforming hydrogen fuel cell generators.
