Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the Modular UPS front internal structure schematic diagram of the utility model preferred embodiment;
Fig. 2 is face, the Modular UPS rear flank internal structure schematic diagram of the utility model preferred embodiment;
Fig. 3 is that the N wiretap of the utility model preferred embodiment connects local schematic diagram.
Embodiment
The Modular UPS of the utility model preferred embodiment as depicted in figs. 1 and 2, comprises power model 10, input copper bar 31 and exports copper bar 32; Wherein, between power model 10 and input copper bar 31, be provided with the first filter disturbed for filtering EMI, and/or be provided with the second filter disturbed for filtering EMI between power model 10 and output copper bar 32.Like this by arranging the first filter and/or the second filter that are used for filtering EMI interference, well inhibit power model 10 to come out to the EMI interference of input port and output port, improve the anti-EMI filter performance of Modular UPS entirety.
Preferably, the first filter of above-mentioned Modular UPS and the second filter are the good pi type filter of filter effect.Wherein, as shown in Figure 2, the first filter comprise be connected to power model 10 and input copper bar 31 between the first electric capacity C1 and the second electric capacity C2, the connection cable between the first electric capacity C1 and the second electric capacity C2 is arranged with ferrite bead (not shown).Second filter comprise be connected to power model 10 and input copper bar 32 between the second electric capacity C3 and the second electric capacity C4, the connection cable between the first electric capacity C3 and the second electric capacity C4 is arranged with ferrite bead (not shown).Ferrite bead is on the not impact of normal input and output electric current (being equivalent to difference mode signal), but for being the equal of then EMI inductance from power model 10 EMI common mode interference signal out, such two-stage EMI electric capacity and EMI inductance (ferrite bead) constitute CLC filter circuit, i.e. pi type filter, the FMI interference coming out to input port and output port from power model 10 can well be suppressed, improve the anti-FMI performance of Modular UPS entirety.
General Modular UPS is when power-on serving, often just cut off input switch and output switch, close maintenance bypass switch and maintenance handover repaiies bypass power supply simultaneously, at this moment uninterrupted power supply is inner because input switch and output switch disconnect do not had electricity, but because UPS switch is all three poles, can only cut off three-phase alternating current and can not cut off N line current, therefore customer service is when power-on serving uninterrupted power supply, can there is certain security risk because of N tape electricity.
In a further embodiment, as shown in Figures 2 and 3, above-mentioned Modular UPS also comprises for cutting off the inner N line of Modular UPS and input N line and exporting the N wiretap 40 of connection of N line.When customer service power-on serving uninterrupted power supply, by disconnecting N wiretap 40, the N line of uninterrupted power supply inside and electrical network and load thoroughly being disconnected, eliminates potential safety hazard during power-on serving.
Preferably, as shown in Figure 3, above-mentioned N wiretap 40 one end connects power source internal N line, and the other end is connected to input N line and exports between N line.
Further, as shown in Figure 1, above-mentioned Modular UPS comprises cabinet 100, and it is anterior that power model 10 is arranged on left side in cabinet 100, so that carry out front attended operation to power model 10.
Further, as shown in Figure 1, in above-mentioned cabinet 100, right front is provided with distribution district, main input switch 21, bypass input switch 22, maintenance bypass switch 23 and output switch 24 is provided with in distribution district, and main input switch 21, bypass input switch 22, maintenance bypass switch 23 and output switch 24 are preferably all previous action, so that user uses.
Further, the N wiretap 40 of above-mentioned Modular UPS is arranged on rear portion in cabinet 100, N wiretap 40 cannot be touched when not dismantling the Rear Door of cabinet 100, to prevent client from operating N wiretap 40, avoid the abnormal risk that uninterrupted power supply causes because N wiretap 40 wrong diagnosis is opened in normal work.
