Periodically carry

Periodically carry on supporting a work to UPS the power:Inside the clearance machine of accumulate a dust, measure the electric voltage of storage battery set, replace unqualified battery, the check fan revolves the system parameter that circumstance and examination regulate UPS etc..Maintenance regulation this text of UPS the power introduced storage battery to float Chong characteristic.

(1)Float to refresh to press floating of storage battery to refresh to flow should satisfy to compensate battery from turn on electricity electric current and maintenance oxygen cycle of demand.The lead sour battery floats to refresh to press to press a row empirical formula assurance:Float to refresh to press=open a new road electric voltage+turn electric voltage (electrolyte specific weight+0.85)very much=V+(0.10~0.18)the V valve controls storage battery of the electrolyte specific weight is a 1.30 gs|cm 3, then open a new road the electric voltage as 2.15 Vs, the past single body battery floats to refresh to press to take 2.25 ± 0.02 Vs|(25 ℃ ).

(2)The deviation(static state deviation and dynamic state deviation) valve that carries electric voltage controls the carrying of storage battery set electric voltage deviation to have two kinds of, 1 kind is quiet to place the electric voltage of appearance of deviation, then open a new road the deviation of electric voltage, this kind of deviation should not over 20 mVs;Two is a dynamic state deviation, then float Chong appearance deviation, this deviation value at float Chong movement to throw in bigger in the early years, circulated 2~3 month future reunions gradual decrease.This is in order to circulating the early oxygen cycle compound appearance still unsteady result in, along with circulate horary increment, the oxygen cycle compound appearance will gradually stabilize and carry electric voltage deviation gradual decrease.So, float the carrying of Chong movement appearance electric voltage deviation value, is bigger than to calm down to place appearance.While floating to refresh to press variety on the average, the deviation is worth also in the variety, float to refresh to press on the average more high, deviation enlarge, whereas the deviation let up, but disproportionate.The surplus capacity of the battery with float Chong to circulate the height that the battery of appearance carries electric voltage have no direct relation, hard from in judgment the battery carry its surplus of electric voltage Gao to have great capacity and carry electric voltage low of its surplus capacity is small.

(3)The value that floats to refresh to flow to float to refresh to flow If should satisfy to compensate battery of from turn on electricity electric current Is and the oxygen compound electric current Ir.Consequently:If ≥ Is+the Ir valve controls the seal completely type lead sour battery it from turn on electricity a rate is pimping, so corresponding to float to refresh to flow a value is also very low.The Japanese standard settles capacity to descend it in 80% sums a day and night from turn on electricity a rate to be no bigger than 0.2%, even if press 1% calculation, then storage battery of from turn on electricity electric current while stipulating temperature(20 ℃ or 25 ℃ ), Is=(C 10|24)×(1|100)=0.00042 C10 A, press the unit Anne's chronometer calculate Is=0.42 mAs|Ah.Again in consideration of the demand that the oxygen cycle reunites, float to refresh to flow to take If=1 mA|the Ah can already satisfy a request.Because from turned on electricity in the middle of the electric current(Is) a big part was used for plank grid corrosion, but the oxygen reunited electric current because of oxygen compound the existence of efficiency, just among them the small part was used to resolve water.Thus, different plank grid material, different manufacturing craft, it floats to refresh to flow to certainly also have a dissimilarity.Floating to refresh to flow is more small and then as well mean to the corrosion electric current of plank grid and used for the electric current that water exhausts also more small.

An Uninterruptible Power Supply or UPS, UPS Power Supply is one of the most cost-effective ways to provide clean high quality power without any break in supply.

(4)Movement life span and plank grid that float to refresh to flow to relate to storage battery with life span decay velocity and lose water to contain closely related degree.The corrosion of plank grid has something to do with sulfuric acid density and electrolyte temperature of electrolyte under same metal alloy material condition:When the battery floats to refresh to press more high, and the electrolyte specific weight is as well high, and float to refresh to flow again greatly, then to the corrosion velocity of plank grid also big, certanly will as well cause temperature's going up, lose water speed, the floating of storage battery Chong movement life span also lowers.A little bit smallly float to refresh to flow will obtain higher float Chong movement of life span.

1.Support time, have to carry on under the sistuation that shut down, the in order to prevent internal high pressure produces an electricity to leave to make the son triggered igbt to result in equipments' breaking down.
2.If having ups the power that maintain the bypass can turn to after maintaining bypass, the maintenance but inner part still takes an electricity at this time.

3. ups the power supports a front as to it's have to carry on from turn on electricity, the square can carry on

4.Support the tool usage vacuum type the hair dryer must can not use wet pack then
