Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the utility model zero-power direct current UPS switched system schematic diagram.
Embodiment
Embodiment as shown in Figure 1, the utility model zero-power direct current UPS switched system comprises charge management module 1, high-tension battery group 2, A-battery group 3, D.C. contactor 4, relay 5 with normally-closed contact 51, first diode 6 and the second diode 7, the charging control end of described charge management module 1 connects described high-tension battery group 2 and A-battery group 3 respectively, described high-tension battery group 2 and A-battery group 3 are connected in series, the negative terminal of described A-battery group 3 connects DC bus negative pole 9, the anode of described A-battery group 3 connects the positive pole of described second diode 7 by described D.C. contactor 4 contact, the anode of described high-tension battery group 2 is connected the positive pole of described first diode 6 with the normally-closed contact 51 of relay 5 by described another contact of D.C. contactor 4, described first diode 6 is connected DC bus positive pole 8 with the second diode 7 negative pole, the coil of described relay 5 connects the civil power test side of described charge management module 1, the voltage of described A-battery group 3 is less than the voltage of DC bus.
When native system runs, each contact of D.C. contactor is in closure state, when civil power is normal, relay coil obtains electric, its normally-closed contact is in off-state, and the voltage of A-battery group is less than DC bus-bar voltage simultaneously, and the second diode is reversed cut-off, DC bus is by mains-supplied, and UPS is in the state of standing ready.When civil power falls or have a power failure, because DC bus-bar voltage sharply declines, make the voltage of A-battery group higher than DC bus-bar voltage, the second diode forward conducting, A-battery group, to DC bus powered, realizes switching without postponing; Simultaneously, charge management module will detect and judge that civil power falls or power down mode in 10ms, make relay coil dead electricity, its normally-closed contact is in closure state, high-tension battery group is loaded on DC bus, makes the first diode forward conducting, the second diode reverse cut-off, the voltage of DC bus is made to be increased to maximum, for equipment provides sufficient power supply.When city power recovery, civil power causes DC bus-bar voltage higher than the voltage of A-battery group, and the second diode is reversed cut-off; Meanwhile, relay coil obtains electric, and its normally-closed contact is in off-state, realizes the isolation of civil power and high-tension battery group, thus realizes the fast automatic no-harass switch of power supply.Native system realizes the Zero-power-consumption standby of UPS and the isolation of battery pack by high-low pressure battery pack and two diodes, reduces long-term stand-by power consumption, has saved enterprise's production cost.
