【正文】 inly embodied in the voltage, resistance and capacity, the conventional detection method mainly measuring voltage, observe the shell signs, check the bolt tightness etc. So that only some representations to the parameter, and cannot master39。 Detection。 Filled, a quiet place 12 h, make a second check sex discharge, after the pletion of the discharge of battery charge。 由于殼體材料、氧復(fù)合效率、閥壓設(shè)計(jì)等綜合技術(shù)欠缺，有些電池池在充放電過(guò)程中，容易產(chǎn)生殼體變形、鼓包甚至裂縫。發(fā)現(xiàn)有電池達(dá)到 1． 8v時(shí)，立即中止測(cè)試。 閥控式鉛酸蓄電池生產(chǎn)對(duì)于技術(shù)工藝要求嚴(yán)格，目前國(guó)內(nèi)電池生 產(chǎn)廠家有 300 多家，各種技術(shù)工藝品類(lèi)繁多，建議在采購(gòu)之前，對(duì)電池進(jìn)行嚴(yán)格的篩選，盡可能選擇生產(chǎn)設(shè)備齊全、技術(shù)力量雄厚、服務(wù)配套完善的品牌企業(yè)。 對(duì)于柴油發(fā)電機(jī)的運(yùn)行維護(hù)和管理，也應(yīng)同蓄電池一起，納入專(zhuān)業(yè)化集中監(jiān)控系統(tǒng)中來(lái)，以便及時(shí)掌握系統(tǒng)蓄電池電源的各項(xiàng)運(yùn)行參數(shù)和工作狀態(tài) 。對(duì)于電池初驗(yàn)的具體要求是：電池在投運(yùn)前，首先進(jìn)行第一次核對(duì)性放電，其容量應(yīng)該不低于 95％，放電完畢后對(duì)電池進(jìn)行充電；充滿(mǎn)后，靜置 1— 2h，進(jìn)行第二次核對(duì)性放電，放電完畢后對(duì)電池進(jìn)行充電 ；充滿(mǎn)后，靜置 1～ 2h，進(jìn)行第三次核對(duì)陛放電，其容量應(yīng)不低于 100％，放電完畢后對(duì)電池進(jìn)行充電。 蓄電池的特征參數(shù)主要體現(xiàn)在電壓、內(nèi)阻和容量上，常規(guī)的檢測(cè)方法主要測(cè)量電壓、觀察外殼體征、檢查螺栓緊固性等，這樣只能掌握一些表象參數(shù)，而不能掌握重要特 !參數(shù)如內(nèi)阻、容量等。西北地區(qū)溫度變化較大 (一 30℃一 +55~C)，變電站通信機(jī)房較少配備空調(diào)，散熱性能較差，環(huán)境溫度對(duì)電池壽命形成直接影響。 關(guān)鍵詞 ： 蓄電池組；電源；檢測(cè)；維護(hù) 引言 電力通信系統(tǒng)各中心機(jī)房安裝配備有大量的蓄電池，其對(duì)通信系 統(tǒng)的運(yùn)行與電能支撐、備用 起到重要的作用。 B. 2021 years urumqi power bureau telemunication room data show that because the battery electric power munication power supply fault from accidents accounted for 35%, in recent years the data interface rapidly, the ratio has risen to 7%. Two sets of data to show that the problem is more serious battery, the battery power supply of security and reliability have a serious threat, investigate its reason, mainly in the following nine aspects: battery design process quality The battery design process exists plate technology design, material design, oxygen posite design, the pressure set A prehensive plan defect, make a battery performance and life have been affected, main performance for battery failure, early leakage water loss, deformation cracks, etc. For simple ascending battery capacity, will the battery plate thin, and increase the number plate, makes the same volume of the casing electrolyte reaction area greatly increased, capacity improve soon, but because thin plate, plate easily corrosion, softening battery, service life and therefore greatly shorten, easy to produce the early failure problems. Because of the low pressure setting, charge once to a certain pressure, control valves will be open Rev., gas is through the valve were leaked, cause the battery fluid loss (usually in a hole or a column valve will find a slightly damp near the liquid), this kind of battery also easy to produce the early failure, valve pressure design and material also has a direct relationship between the shell. Due to shell material, oxygen posite efficiency, valve design pressure, and other prehensive technology lack, some batteries in the process of charging and discharging pool, easy to produce the shell deformation, beat even crack. the influ
