Description
Technical field
The utility model relates to a kind of charging device, specifically, relates to a kind of portable UPS charger for emergency.
Background technology
At present, each factories and miness use the modern automation control equipment such as PLC (programmable logic controller (PLC)), DCS (scattered control system) in a large number, and this just requires service-strong ups power (uninterrupted power supply).Online power supply UPS, causes overdischarge because interruption duration is long sometimes, such as: cell voltage by normal nominal voltage 192V, (save by 12V × 16, generally can to more than 200V) drop to about 110V, thus cannot start shooting, if charged not in time, battery may thoroughly damage.
The direct current of about 13V or pulsating direct current is preferably used to charge respectively to single battery to the batteries charging of overdischarge, because 16 batteries Battery pack number ratio are more, to seem trouble and want seeking time long to the charging of single battery, it is larger obviously to implement difficulty.
Also have a kind of safe way, be exactly use special charger to batteries charging, but not only price is expensive to the batteries charging of power supply UPS to use special charger, and maintenance personal's field service, carry very inconvenient.Requiring to be pressed for time, task various in this defect especially outstanding.
Utility model content
The technical problem that the utility model solves is to provide a kind of portable UPS charger for emergency, features such as having simple circuit, cost is low, volume is little, be easy to carry.
Technical scheme is as follows:
A kind of portable UPS charger for emergency, comprises current-limiting resistance R1, rectifier diode D1, cell terminal A, cell terminal B and battery pack control switch SW; Described current-limiting resistance R1 and rectifier diode D1 is in series, described cell terminal B is connected to the negative pole of described rectifier diode D1, described cell terminal A is connected to the negative pole of described battery pack control switch SW, and the positive pole of described battery pack control switch SW is connected to current-limiting resistance R1.
Further: the parameter of described current-limiting resistance R1=40 Ω, described rectifier diode D1 is 10A, 400V.
Compared with prior art, technique effect of the present utility model comprises:
1, the utility model designs, features such as having simple circuit, cost is low, volume is little, be easy to carry according to using the factories and miness device context of ups power demand that is actual and that meet work on the spot to set out.
2, the utility model can meet on line type UPS power supply well, carries out precharge to the battery pack of overdischarge, and making battery voltage be charged to UPS in advance can normal boot-strap.
Accompanying drawing explanation
Fig. 1 is the circuit connection diagram of portable UPS charger for emergency in the utility model.
Embodiment
Consider that ups power carries charging circuit, reach about 170V at battery voltage and just can charge normal.The utility model carries out precharge to the battery pack of overdischarge, make battery voltage be charged in advance UPS can normal boot-strap charging magnitude of voltage.
As shown in Figure 1, be the circuit connection diagram of portable UPS charger for emergency in the utility model.
Portable UPS charger for emergency comprises: current-limiting resistance R1, rectifier diode D1, cell terminal A, cell terminal B and battery pack control switch SW; Wherein, current-limiting resistance R1, rectifier diode D1 are in series, and cell terminal B is connected to rectifier diode D1 negative pole, and cell terminal A is connected to the negative pole of battery pack control switch SW, and the positive pole of battery pack control switch SW is connected to current-limiting resistance R1.
In this preferred embodiment, the parameter of R1=40 Ω, D1 is 10A, 400V, like this, when accessing 220 civil power, obtains the Rectified alternating current of about 4A after rectification.
Current-limiting resistance R1 for improvement of battery pack nominal capacity and determine battery voltage, general setting charging current is safer within 4A.
During the battery pack overdischarge of online power supply UPS when discovered, first battery switch is disconnected, take out battery pack, (A connects battery anode the negative pole of battery pack and positive pole to be connected respectively to cell terminal B and cell terminal A, B connects battery electrode), closed battery pack control switch SW, 220V civil power is through current-limiting resistance R1 current limliting, after rectifier diode D1 rectification, obtain the Rectified alternating current of about 4A to batteries charging, when batteries charging is to after suitable, open battery pack control switch SW, disconnect 220V civil power, disconnect cell terminal A, the connection of cell terminal B and battery pack, the positive and negative electrode of battery pack is received again on UPS correlated inputs terminal.After start, the charging circuit of UPS can normally charge to battery pack.
This equipment can facilitate factories and miness maintenance personal to carry, requiring to be pressed for time, task various in, process ups power in time, shorten working hours and workload, can greatly increase work efficiency, increase productivity effect.
