不錯蓄電池常用連接方式
不錯蓄電池廣泛應(yīng)用在比如UPS電源，EPS電源，直流屏，太陽能路燈等等！下面給大家簡單講訴一下不錯蓄電池是怎么來連接UPS電源的！
1、首先，頭腦要清晰，安裝環(huán)境要清凈，人要少，不要有心事，連接方案要清楚，安裝時手機(jī)建議關(guān)掉，不與客戶聊天，較不能邊安裝邊回答充滿好奇心的客戶喋喋不休的一連串的問題，這樣會分神，很容易出事;


2、不錯蓄電池上架前要進(jìn)行物理檢查，并測量開路電壓，以免返工;連接線的一端與電池相連時，另一端應(yīng)進(jìn)行絕緣保護(hù)或握在手心，防止搭到不該搭的地方，造成打火;


3、連接線的一端已接好，另一端再連接時應(yīng)輕輕點(diǎn)一下要連接的較柱，即使連錯了也只是在較柱上和連線上打一點(diǎn)火而已，不至于釀成大禍;或測量要連接的兩點(diǎn)的壓差，為零則可以連接;


4、兩人同時連接時，對應(yīng)的不錯蓄電池組應(yīng)無連接或電位關(guān)系。因?yàn)閮扇藶橥娢?或隨時變成同電位，如同時接觸電池架)，各自連接的電池如存在電位差，則電池和二人形成回路，可能發(fā)生電擊事故;


5、電池組串聯(lián)完畢后，不錯蓄電池組的總正和總負(fù)之間電壓比較高，在向MCCB(電池開關(guān))連接時，每根線都應(yīng)先連到MCCB，再連到對應(yīng)的電池端;或在電池組中留一斷點(diǎn)，完成MCCB與UPS蓄電池組的連接后再連接斷點(diǎn);對于多組并聯(lián)的電池組，應(yīng)每一組都留斷頭，并在MCCB端連接后分別用萬用表檢測極性再將斷頭連接。


由于電池內(nèi)阻為毫歐級，因此采用常規(guī)的兩端子測量方法測量誤差較大，在此采用四端子測量方式。測量時兩個端子施加一頻率為
Because the internal resistance of the battery is millieu level, the conventional two terminal measurement method has great error, and the four terminal measurement method is adopted. At the time of measurement, two terminals are applied in a frequency

的恒定交流激勵電流信號，另兩個端子用于測量。測量工作原理圖如圖1所示，響應(yīng)信號是指蓄電池注入交流恒流源后，在其兩端測出的交流電壓信號。而正弦信號是經(jīng)D/A產(chǎn)生的作為壓控恒流源的輸入信號。
A constant AC excitation current ** and the other two terminals are used for measurement. The working principle diagram is shown in Figure 1. The response ** is the AC voltage ** measured at both ends after the battery is injected into the AC constant current source. Sinusoidal ** is generated by D/A as the input ** of voltage controlled constant current source.


蓄電池作為電源系統(tǒng)停電時的備用電源，已廣泛的應(yīng)用于工業(yè)生產(chǎn)、交通、通信等行業(yè)。如果電池失效或容量不足，就有可能造成重大事故，所以必須對蓄電池的運(yùn)行參數(shù)進(jìn)行全面的在線監(jiān)測。蓄電池狀態(tài)的重要標(biāo)志之一就是它的內(nèi)阻。無論是蓄電池即將失效、容量不足或是充放電不當(dāng)，都能從它的內(nèi)阻變化中體現(xiàn)出來。因此可以通過測量蓄電池內(nèi)阻，對其工作狀態(tài)進(jìn)行評估。目前測量蓄電池內(nèi)阻的常見方法有：
Battery as a backup power source when power system is outage, has been widely used in industrial production, transportation, communications and other industries. If the battery fails or the capacity is insufficient, it is possible to cause major accidents. Therefore, the on-line monitoring of the operation parameters of the battery must be carried out. One of the important signs of the battery state is its internal resistance. Whether the battery is going to fail, the capacity is insufficient or the charge and discharge is not proper, it can be reflected from its internal resistance changes. Therefore, the working state of the battery can be evaluated by measuring the internal resistance of the battery. The common methods for measuring the internal resistance of the battery are
（1）密度法
(1) density method
密度法主要通過測量蓄電池電解液的密度來估算蓄電池的內(nèi)阻，常用于開口式鉛酸電池的內(nèi)阻測量，不適合密封鉛酸蓄電池的內(nèi)阻測量。該方法的適用范圍窄。
Density method is used to estimate the internal resistance of the battery by measuring the density of the battery electrolyte, which is often used to measure the internal resistance of the open lead-acid battery, which is not suitable for the internal resistance measurement of the sealed lead-acid battery. The application of this method is narrow.
（2）開路電壓法
(2) open circuit voltage method
開路電壓法是通過測量蓄電池的端電壓來估計(jì)蓄電池內(nèi)阻，精度很差，甚至得出錯誤結(jié)論。因?yàn)榧词挂粋€容量已經(jīng)變得很小的蓄電池，再浮充狀態(tài)下其端電壓仍可能表現(xiàn)得很正常。
The open circuit voltage method is used to estimate the internal resistance of the battery by measuring the terminal voltage of the battery. The accuracy is very poor, and even the wrong conclusion is obtained. Because even if a battery capacity has become very small, then the floating state of terminal voltage is still likely to be normal.
（3）直流放電法
(3) direct current discharge method
直流放電法就是通過對電池進(jìn)行瞬間大電流放電，測量電池上的瞬間電壓降，通過歐姆定律計(jì)算出電池內(nèi)阻。雖然這種方法在實(shí)踐中也得到了廣泛的應(yīng)用，但是它也存在一些缺點(diǎn)。如用該方法對蓄電池內(nèi)阻進(jìn)行檢測必須是在靜態(tài)或是脫機(jī)狀態(tài)下進(jìn)行，無法實(shí)現(xiàn)在線測量。而且大電流放電會對蓄電池造成較大的損害，從而影響蓄電池的容量及壽命。
The DC discharge method is to measure the instantaneous voltage drop on the battery by discharging the battery instantaneously, and calculate the internal resistance of the battery by Ohm's law. Although this method has been widely applied in practice, it also has some shortcomings. If we use this method to detect the internal resistance of battery, it must be carried out under static or offline state, and online measurement can not be achieved. Moreover, the large current discharge will cause great damage to the battery, which will affect the capacity and life of the battery.
（4）交流注入法
(4) AC injection method
交流法通過對蓄電池注入一個恒定的交流電流信號IS，測量出蓄電池兩端的電壓響應(yīng)信號Vo，以及兩者的相位差
In the AC method, a constant current ** IS is injected into the battery, and the voltage response ** Vo at both ends of the battery is measured, and the phase difference between them is measured.
