Embodiment
In order that those skilled in the art more fully understand the technical scheme in the utility model, below in conjunction with this reality
With the accompanying drawing in new embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that
Described embodiment is only the utility model part of the embodiment, rather than whole embodiments.Based on the utility model
In embodiment, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, it should all belong to the scope of the utility model protection.
The utility model discloses a kind of UPS uninterrupted power sources with accessory power supply, UPS uninterrupted power sources include parallel connection
Set the first loop and second servo loop, the first loop include be sequentially connected to civil power and load between transformer, rectifier,
Inverter, and one end are electrically connected at the battery between rectifier and inverter, and second servo loop includes accessory power supply and liter
Depressor, first loop or second servo loop power to the load.
Join shown in Fig. 1, a kind of UPS uninterrupted power sources with accessory power supply in the specific embodiment of the utility model one,
The UPS uninterrupted power sources include the first loop 10 and the second servo loop 20 being arranged in parallel.
Wherein, the first loop 10 includes the transformer 11, rectifier 12, inverter being sequentially connected between civil power and load
13, and one end is electrically connected at the battery 14 between rectifier 12 and inverter 13, the front end of transformer 11, which is also connected, to be provided with
Fuse 15.
Second servo loop 20 includes accessory power supply 22 and booster 21.
Further, first switch S1 is provided with the first loop 10, is provided with second switch S2 in second servo loop 20, first opens
Closing S1 and second switch S2, one and only one is in the conduction state
With reference to shown in Fig. 2, wave filter 16 is additionally provided between the transformer 11 and rectifier 12 in the present embodiment, wave filter is
