Abstract
An uninterruptible power supply (USP) alternating current dual input device comprises a main alternating current power supply, a rectifier, an inverter, a static switch and a standby alternating current power supply. The main alternating current power supply is connected with a load through a switch S1, the rectifier, the inverter, the static switch and a switch S3. The standby alternating current power supply is connected with the static switch. The utility model relates to the technical field of an uninterruptible power supply, in particular to a dual power supply alternating current uninterruptible power supply device. The UPS alternating current dual input device realizes uninterruptible power supply work of the load through the standby alternating current power supply.
Description
Technical field
The utility model relates to a kind of uninterrupted power supply technical field, and particularly a kind of duplicate supply exchanges the uninterrupted power supply device.
Background technology
UPS is " uninterruptible power system ", and in the industrial automation control system, as DCS, PLC etc., most automatic control equipment needs long-term stable, reliable, the high-quality uninterrupted power supply that is equipped with, to guarantee the normal operation of production line.Traditional UPS ac uninterrupted power supply adopts one tunnel AC power input, includes main AC power, batteries, rectifier, inverter and static switch, and main AC power is supplied with the auto by pass of UPS respectively, manually keeped in repair bypass and rectifier.Rectifier is to battery charging, and also needing provides direct current energy to inverter.Inversion system is followed the tracks of the phase place of alternating current input power supplying, direct current energy is converted to alternating current input power supplying exports with frequency homophase and stable AC power.
Its deficiency is: traditional UPS has only the input of one tunnel AC power, when main AC power failure, provides direct current energy by batteries for inverter, but the weak point of holding time, after storage battery had been put electricity, powering-off state will appear in load, influenced the operation of load.
The utility model content
The purpose of this utility model just provides a kind of UPS and exchanges dual input apparatus, and it realizes the work of the long-time constantly electricity of load by standby AC power.
The purpose of this utility model is to realize by such technical scheme, it includes main AC power, rectifier, inverter and static switch, it also includes standby AC power, main AC power is connected with load with switch S 3 by switch S 1, rectifier, inverter, static switch, and standby AC power is connected with static switch.
During work, main AC power is a rectifier power supply through switch S 1, and the direct current of rectifier output is converted to standby AC power by inverter and exports to load with frequency homophase and stable AC power; When main AC power was cut off the power supply, it was electric that static switch automatically switches to standby AC power, constantly electricity work of proof load, and simultaneity factor is keeped in repair the alert notice maintenance personal.
Owing to adopted technique scheme, the utlity model has following advantage: constantly electricity work of proof load.
Description of drawings
Description of drawings of the present utility model is as follows.
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
A kind of UPS exchanges dual input apparatus, it includes main AC power, rectifier, inverter and static switch, it also includes standby AC power, main AC power is connected with load with switch S 3 by switch S 1, rectifier, inverter, static switch, and standby AC power is connected with static switch.
During work, main AC power is a rectifier power supply through switch S 1, and the direct current of rectifier output is converted to standby AC power by inverter and exports to load with frequency homophase and stable AC power; When main AC power was cut off the power supply, it was electric that static switch automatically switches to standby AC power, constantly electricity work of proof load, and simultaneity factor is keeped in repair the alert notice maintenance personal.
The utility model can also include batteries, and batteries is connected with the output of rectifier by switch S 2.When main AC power is electric, be battery charging simultaneously, when main AC power is cut off the power supply, batteries is converted to the required AC power of load by inverter automatically and is electric, during the batteries discharge off, static switch automatically switches to standby AC power, and standby AC power is an electric, and simultaneity factor is keeped in repair the alert notice maintenance personal.
For the ease of maintenance, standby AC power is connected with load by switch S 4.When main AC power, rectifier, batteries, inverter or static switch break down, Closing Switch S4, standby AC power is an electric directly, is convenient to staff's maintenance.
Claims (3)
1. a UPS exchanges dual input apparatus, it includes main AC power, rectifier, inverter and static switch, it is characterized in that: it also includes standby AC power, main AC power is connected with load with switch S 3 by switch S 1, rectifier, inverter, static switch, and standby AC power is connected with static switch.
