The short circuit phenomenon of lead-acid battery is important as possible 1, the open circuit voltage is low, the closed circuit voltage (discharge) quickly reaches the termination voltage. 2, when the large current is discharged, the end voltage drops rapidly to zero. 3.

4, when charging, the voltage rises very slow, always keeps a low value (sometimes drop to zero). 5, when charging, the electrolyte temperature rise is very fast. 6, when charging, the electrolyte density increases very slow or almost no change.

7, when charging, no air bubble or taking gas is very late. The causes of short circuits caused by lead-acid storage batteries are: 1, the partition quality is not good or defect, allowing the polar active material to pass through, causing positive, negative plate virtual contact or direct contact. 2, the partition block is connected to the positive and negative plate.

3, the active substance is expanded from the active material due to excessive deposition of the active substance, resulting in positive and negative plates to connect to the deposits in the lower edge or side edges of the positive, negative electrode plates. 4, the conductive object falls into the battery, the negative plate is connected. 5.

The lead stream formed when the welding pole is not exhausted, or the lead beans are present during the positive and negative plate during the assembly, and the partition is damaged during the charge and discharge process. Drënner ass wichteg, de Ladestroum ass ze grouss, d&39;Single Batterie Opluedspannung ass méi wéi 2,4V, et gëtt e Kuerzschluss oder d&39;Bläi-Sauer Batterie Kuerzschluss verursaacht duerch Kuerzschluss oder lokal Entladung, Temperaturerhéijung, an de Ventilausfall Phänomen gëtt analyséiert.

Approche. 1, reduzéiert d&39;Ladestroum, reduzéiert d&39;Ladespannung, kontrolléiert ob de Sécherheetsventilkierper blockéiert ass. Regelméisseg Opluedstatioun.

D&39;Bläi-Sauer Batterie Schwemmspannung an d&39;Entladungsspannung am UPS Kraaftsystem, vill vun deenen op de bewäertte Wäert während der Fabrik agestallt goufen, an d&39;Gréisst vum Entladungsstroum erhéicht mat der Erhéijung vun der Belaaschtung, an d&39;Laascht soll raisonnabel ugepasst ginn. Zum Beispill, d&39;Zuel vun Uwendungen vun elektroneschen Apparater wéi Computeren. Ënner normalen Ëmstänn däerf d&39;Laascht net méi wéi 60% vun der UPS-bewäertter Belaaschtung iwwerschreiden.

An dësem Beräich gëtt d&39;Batterie net exzessiv Entladung. D&39;Bläi-Sauer Batterie Stockage wäert Deel Kapazitéit verléieren wéinst Self-Entladung, an dofir, ier d&39;Bläi-Sauer Batterie benotzt gëtt, soll d&39;Rescht Kapazitéit vun der Batterie no der Batterie Open Circuit bestëmmt ginn, an dann d&39;Batterie ergänzen fir d&39;Batterie ergänzen. Batterie fir Standby Regaler, zousätzlech Opluedstatioun soll all 3 Méint duerchgefouert ginn.

Dir kënnt d&39;Batterie gutt oder schlecht bestëmmen andeems Dir de puffy Batterie Open Circuit moosst. 2, as an example of 12V battery, if the open circuit voltage is higher than 12.5V, it means that the battery energy is more than 80%, if the open circuit voltage is below 12.

5V, it should be replenished immediately. Wann d&39;Open Circuit Spannung manner wéi 12V ass, heescht et datt d&39;Batterielagerung elektresch manner wéi 20% ka sinn, d&39;Batterie ass net fäeg. Wann d&39;Batterie verkierzt ass, kann de Kuerzschlussstroum Honnerte vun Ampere erreechen.

De méi kuerze Kontakt ass verbonnen, dest méi grouss ass de Kuerzschlussstroum, sou datt all Verbindungsdeeler vill Hëtzt hunn, an d&39;Hëtzt vum schwaache Link ass méi grouss, d&39;Verbindung ass geblosen, Kuerzschluss-Phänomen. The battery is partially possible to explorate the explosion, and the spark is caused when the connection is blown at the connection, which can cause the battery explosion; if the battery short circuit is shorter or the current is not particularly large, it may not cause connection The phenomenon is blown, but the short circuit will still have an overheating phenomenon, which will damage the binder around the connecting strip, so that it leaves a leakage. When installing the lead-acid battery, the tools should be used should take insulation measures.

When connecting, the electrical appliance other than the battery should be connected, and the inspection is not short-circuit, and finally the battery, the wiring specification should be good, prevent the overlapping pressure rupture. Through these meticulous work, it can better prevent lead-acid battery short circuits, so that the lead-acid battery is safer and longer.
