Function and characteristic that the utility model utilizes existing storage battery, charger, discharge instrument to possess, it is effectively integrated, use by this device, the battery discharging overall process is carried out effective intelligent monitoring switch, improve fail safe and reliability in 110KV, the 35KV transformer station storage battery full capacity property the checked process of the test with the unremitting instantaneous mode of realization; Needn't utilize batteries, save the heavy reserve battery of carrying, save human and material resources, alleviate operating personnel's labour intensity.
[description of drawings]
Fig. 1 is the utility model schematic diagram.
[embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated:
The online discharge intelligent controller of a kind of batteries, include chip CPU and the storage battery port COM1 that is connected with storage battery, charging port COM2 that is connected with the charger power supply and the discharge port COM3 that is connected with discharge instrument, between storage battery port COM1 and charging port COM2, be connected with the charge switch J1 that can realize switching charge function, J2, can be when also being connected with discharge with the spacer assembly 1 of storage battery and charger isolation, between storage battery port COM1 and discharge port COM3, be connected with the discharge switch J3 that can realize discharging function, J4 is connected with first voltmeter V1 that shows charger voltage and the first ammeter I1 that shows battery current on charging port COM2, on storage battery port COM1, also be connected with the second voltmeter V2 that shows the storage battery real-time voltage, on discharge port COM3, be connected with the second ammeter I2 that shows discharging current, described charge switch J1, J2, discharge switch J3, J4, spacer assembly 1, the first voltmeter V1, the first ammeter I1, the second voltmeter V2, the second ammeter I2 is connected with chip CPU respectively.
Described spacer assembly 1 is two diode D1, D2, and described diode D1, D2 are connected in parallel with charge switch J1, J2 respectively.
The positive pole of described diode D1 is connected with storage battery port COM1 is anodal, the negative pole of diode D1 is connected with charging port COM2 is anodal, the positive pole of described diode D2 is connected with charging port COM2 negative pole, and the negative pole of diode D2 is connected with storage battery port COM1 negative pole.
The online discharge intelligent controller of batteries charge switch J1, J2 and discharge switch J3, J4 before device energising start are in off-state, when the online discharge intelligent controller energising of batteries start transfers direct current system to floating charge state, charge switch J1, J2 closure, discharge switch J3, J4 still locate to disconnect; Reach the effect of storage battery and the direct line of charger.
During regular picture, after connecting line and discharge instrument setting were finished, by the artificial input validation discharge in the external world, chip CPU sent the discharge order, and turn off charge switch J1, J2, diode D1, D2 play storage battery and charger buffer action; Closed discharge switch J3, J4 begin discharge.In discharge process, charger voltage is higher than battery tension, and owing to diode D1, D2 effect, charger stops charge in batteries, and storage battery stops charger being powered.
In the online discharge process of batteries, escaping because of line switching (electromagnetic mechanism) tripping operation back reclosing action (or the monitor remote console switch closes a floodgate) influences normally carrying out of discharge test.During regular picture, the effect first ammeter I1 no current because of diode D1, D2, when meeting electromagnetic mechanism switch combined floodgate, charger can't be exported the required whole electric currents that close a floodgate, diode D1, D2 are with instantaneous conducting, the first ammeter I1 is instantaneous electric current, and chip CPU time-delay 0.5S sends and withdrawing from the discharge order, has guaranteed that the electromagnetic mechanism switch closes a floodgate and discharge test is proceeded.
After regular picture finished, discharge instrument stopped discharge; Disconnect discharge switch J3, J4, charger is to the storage battery boost charge behind closed charge switch J1, the J2.Condition is judged that by the second ammeter I2 when discharge instrument stopped to discharge, the second ammeter I2 was 0; Chip CPU sends and withdraws from the discharge order, and charge switch J1, J2, electricity disconnect pass J3, J4 and put the floating charge position, reach charge function.
Occur direct current system dead electricity fault in the discharge process, as the first voltmeter V1 during less than the second voltmeter V2, dead electricity (or charger fault no-output) occurs exchanging and cause the charger dead electricity, diode D1, D2 moment conducting guarantee the direct current system uninterrupted power supply.By the first ammeter I1, the first voltmeter V1 failure judgement, the first ammeter I1 is greater than 0; Chip CPU time-delay 0.5S sends and withdraws from discharge condition, disconnects the discharge switch J3, the J4 that are discharging, finishes discharge; Closed charge switch J1, J2 are powered to charger by storage battery with diode D1, D2 are in parallel.Charge switch J1, J2, discharge switch J3, J4 put the floating charge position, reach storage battery to the charger function of supplying power.
