Description
Technical field:
The present invention relates to the uninterrupted ac power supply system of a kind of power communication machine room, belong to technical field of electric power communication.
Background technology:
In power communication machine room, the alternating current equipments such as all kinds of server, the network switch, Power Supply Monitoring equipment, conference system, MCU are powered by ac power supply system.In order to ensure the stability that alternating current equipment is powered, usually ups power system is adopted to be that power communication machine room carries out Alternating Current Power Supply.Existing power communication machine room ac power supply system as shown in Figure 1, AC power distribution cabinet/AC distribution panel 1 connects UPS1 interchange input switch 2 and exchanges input switch 3 with UPS2, and UPS2 interchange input switch 3 is connected UPS1 unit power-supply device 6 respectively and UPS2 unit power-supply device 7, UPS1 unit power-supply device 6 is connected two group storage batteries 5 respectively separately with UPS2 unit power-supply device 7 for UPS1 interchange input switch 2.Four group storage batteries 5 are as the back-up source of UPS1 unit power-supply device 6 and UPS2 unit power-supply device 7.UPS1 unit power-supply device 6, UPS2 unit power-supply device 7 are as UPS main input, be connected to together with inputting 4 with UPS bypass civil power and rack 8 on, and rack 8 is connected in UPS load 9, UPS load 9 is connected respectively on the industrial insert row in each alternating current equipment cabinet.The main power supply of the different alternating current equipments in same alternating current equipment cabinet is connected to the industrial insert row in this equipment cabinet, realizes Alternating Current Power Supply.It is as follows to there is hidden danger in the power communication machine room ac power supply system shown in Fig. 1:
1) this ac power supply system only has a road AC power distribution cabinet/AC distribution panel 1 for UPS main input and UPS bypass civil power input 4 power supply, once AC power distribution cabinet/AC distribution panel 1 breaks down, then UPS main input and UPS bypass civil power input 4 will be interrupted simultaneously, and four group storage batteries 5 only can be relied on to be that in power communication machine room, each alternating current equipment is powered.Due to the impact of many factors, current machine room does not still possess 7x24 hour ability on duty.And the factor that AC power distribution cabinet/AC distribution panel 1 may be caused to break down is a lot, thus once the time of recovering normal required maintenance of breaking down longer.
2) in this ac power supply system, UPS load 9 directly connects the industrial insert row in each alternating current equipment cabinet, for each alternating current equipment in cabinet is powered.Once short circuit appears in certain alternating current equipment, owing to not having secondary AC distribution device to protect, be easy to cause in same alternating current equipment cabinet other alternating current equipment short circuit be simultaneously connected on same industrial insert row, time serious, even can cause UPS load 9 short circuit.
Therefore, the power communication machine room alternating-current system shown in Fig. 1 has larger potential safety hazard.
Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art and a kind of uninterrupted ac power supply system of power communication machine room that can ensure all alternating current equipment safe and stable operations in power communication machine room is provided.
Object of the present invention can be reached by following measure: the uninterrupted ac power supply system of a kind of power communication machine room, it is characterized in that it comprises two-way AC power distribution cabinet/AC distribution panel, the two-way AC power distribution cabinet/AC distribution panel diverter switch that all links with inlet wire is connected, inlet wire linked switch connects UPS1 respectively and exchanges input switch, UPS2 exchanges input switch and the input of UPS bypass civil power, UPS1 exchanges input switch and connects UPS1 unit power-supply device, UPS2 exchanges input switch and connects UPS2 unit power-supply device, UPS1 unit power-supply device is connected two group storage batteries respectively separately with UPS2 unit power-supply device, UPS1 unit power-supply device, UPS2 unit power-supply device is all connected and rack with the input of UPS bypass civil power, and rack connects UPS load, UPS load is connected with the secondary Alternating Current Unit in each alternating current equipment cabinet.
The present invention can produce following good effect compared with the prior art:
The present invention realizes two AC power distribution cabinet/AC distribution panel and inputs to inlet wire interlock diverter switch, realizes the redundant configuration of UPS Alternating Current Power Supply in machine room.Break down once a certain road AC power distribution cabinet/AC distribution panel, AC distribution can be provided by an other road AC power distribution cabinet/AC distribution panel for UPS1 interchange input switch exchanges input switch with UPS2 by inlet wire linked switch simultaneously.Under extreme case, when two-way AC distribution device all breaks down, can be that alternating current equipment carries out Alternating Current Power Supply by UPS unit power-supply device by batteries.
In the present invention, UPS main input and UPS bypass civil power input by and rack is that alternating current equipment is powered.Under normal circumstances, UPS1 unit power-supply device 6 and UPS2 unit power-supply device 7 are simultaneously for alternating current equipment is powered.When a certain road UPS unit power-supply device breaks down, a remaining road UPS unit power-supply device can by also rack can separately for alternating current equipment be powered.Under extreme case, when two-way UPS unit power-supply device all breaks down, alternating current equipment can be input as by UPS bypass civil power and AC distribution is provided.
In the present invention, UPS load is connected to industrial insert row, for alternating current equipment is powered by two-way secondary AC distribution device.By secondary AC distribution device, industrial insert row can obtain the electric current of safety and stability, and alternating current equipment not easily occurs the faults such as short circuit.And the alternating current equipment power supplys such as current server are mostly two-way or four roads, and active and standby interchange inputs.Under the active and standby industrial insert row received respectively under two-way secondary AC distribution device that the two-way of alternating current equipment or four tunnels exchange in input, there are 2 benefits: 1. when a certain road secondary AC distribution device breaks down, can be that alternating current equipment is powered by an other road AC distribution device, achieve the redundant configuration of alternating current equipment power supply input, substantially increase the reliability of Alternating Current Power Supply.2., when short circuit appears in certain alternating current equipment, owing to there being secondary AC distribution device to protect, the alternating current equipment under other secondary AC distribution devices can not be had influence on.
In sum, the invention provides the uninterrupted ac power supply system of a kind of power communication machine room, meet the high reliability request that alternating current equipment in machine room is powered.
