What is the cause of short circuit inside the lead-acid battery?

ଲେଖକ: ଆଇଫ୍ଲୋପାୱାର - ซัพพลายเออร์สถานีพลังงานแบบพกพา

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. هيٺ اهم آهي، چارجنگ ڪرنٽ تمام وڏو آهي، سنگل بيٽري چارجنگ وولٽيج 2.4V کان وڌيڪ آهي، شارٽ سرڪٽ آهي يا ليڊ ايسڊ بيٽري شارٽ سرڪٽ شارٽ سرڪٽ يا مقامي ڊسچارج جي ڪري ٿئي ٿو، گرمي پد ۾ واڌ، ۽ والو جي ناڪامي جي رجحان جو تجزيو ڪيو ويندو آهي.

طريقو. 1، چارجنگ ڪرنٽ گھٽايو، چارجنگ وولٽيج گھٽايو، چيڪ ڪريو ته ڇا حفاظتي والو باڊي بلاڪ ٿيل آهي. باقاعده چارجنگ ڊسچارج.

يو پي ايس پاور سسٽم ۾ ليڊ ايسڊ بيٽري فلوٽنگ وولٽيج ۽ ڊسچارج وولٽيج، جن مان ڪيترائي فيڪٽري دوران ريٽيڊ ويليو تي ڪمشن ڪيا ويا آهن، ۽ ڊسچارج ڪرنٽ جو سائز لوڊ جي واڌ سان وڌي ٿو، ۽ لوڊ کي مناسب طور تي ترتيب ڏيڻ گهرجي. مثال طور، اليڪٽرانڪ ڊوائيسز جهڙوڪ ڪمپيوٽرن جي ايپليڪيشنن جو تعداد. عام حالتن ۾، لوڊ UPS ريٽيڊ لوڊ جي 60٪ کان وڌيڪ نه هجڻ گهرجي.

هن حد اندر، بيٽري تمام گهڻو خارج نه ٿيندي آهي. ليڊ ايسڊ بيٽري اسٽوريج خود خارج ٿيڻ جي ڪري جزوي گنجائش وڃائي ڇڏيندو، ۽ تنهن ڪري، ليڊ ايسڊ بيٽري کي استعمال ۾ آڻڻ کان اڳ، بيٽري جي باقي گنجائش کي بيٽري جي اوپن سرڪٽ جي مطابق طئي ڪيو وڃي، ۽ پوءِ بيٽري کي اضافي ڪرڻ لاءِ بيٽري کي وڌايو وڃي. اسٽينڊ بائي شيلف لاءِ بيٽري، اضافي چارجنگ هر 3 مهينن ۾ ڪئي وڃي.

توهان بيٽري جي سٺي يا خراب هجڻ جو اندازو ان جي ڦڦڙيل بيٽري جي اوپن سرڪٽ کي ماپي ڪري لڳائي سگهو ٿا. 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. جيڪڏهن اوپن سرڪٽ وولٽيج 12V کان گهٽ آهي، ته ان جو مطلب آهي ته بيٽري اسٽوريج اليڪٽرڪ 20٪ کان گهٽ ٿي سگهي ٿي، بيٽري قابل ناهي. جڏهن بيٽري شارٽ سرڪٽ ٿيندي آهي، ته شارٽ سرڪٽ ڪرنٽ سوين ايمپس تائين پهچي سگهي ٿو.

جيترو ننڍو رابطو لاڳاپيل هوندو، اوترو ئي وڏو شارٽ سرڪٽ ڪرنٽ هوندو، تنهن ڪري سڀني ڳنڍيندڙ حصن ۾ تمام گهڻي گرمي هوندي، ۽ ڪمزور لنڪ جي گرمي وڌيڪ هوندي، ڪنيڪشن ڦاٽل هوندو، شارٽ سرڪٽ جو رجحان. 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.
