These series features silver-coated terminals, which improve the electric conductivity. To optimize high rate performance a unique paste formula have been applied to the plate technology.

This series also features AGM separators, which use less electrical resistance to improve the current.

This series is specifically designed for 19 or 23 inch power cabinets. The front terminals make the installation and maintenance easy. The unique valve design reduces water loss and prevents air going inside the battery.

Capacity

Amount of charge available from a battery or cell. Measured in ampere-hours. There are various sub definitions of capacity as listed below depending on the conditioned under which it is measured.

Actual Capacity

Cell capacity of a fully formed and fully charged cell when measured under non-standard conditions including non-standard end of discharge voltage.

Available Capacity

Capacity of a fully formed and fully charged cell delivered under non-standard conditions including non-standard end of discharge voltage.

Dischargeable Capacity

Capacity which a partially discharged cell can deliver before it becomes fully discharged or the amount of capacity that can be withdrawn after a limited charge input.

容量

從電池或電池中獲得的電量。以安培小時為單位。下面列出了各種能力的子定義，這取決于其測量所依據(jù)的條件。

有效容量，實際生產(chǎn)（能）力

在包括非標準放電電壓在內(nèi)的非標準條件下測量*成形和全充電電池的電池容量。

有效功率，可用功率，有效容量

在包括非標準放電電壓的非標準條件下交付的*成形和全充電電池的容量。

可分辨率卡帕提

部分放電電池在*放電之前可以提供的容量，或者在有限的電荷輸入后可以撤回的容量。

Nominal Capacity

Capacity typically delivered under standard conditions; a value greater than rated capacity which is a minimum value.

Permanent loss of Capacity

Reduction in cell capacity from the "fully formed, as new" value, measured under standard rating conditions, that is not recoverable by reconditioning.

Rated Capacity

Capacity value shown in the specification sheet. The minimum expected capacity when a new, but fully formed, cell is measured under standard conditions. The basis of the C rate. Note that rated capacities depend on the standard conditions used which may vary from battery to battery.

Residual Capacity

Capacity remaining after discharge.

Retained Capacity

Capacity remaining in a cell after an open circuit rest period. The result of self- discharge.

Standard Capacity

Cell capacity measured under standard conditions.

Temporary Loss of Capacity

Reduction in cell capacity that is recovered when the cell is reconditioned.

Cell

Electrochemical unit, composed of positive and negative electrodes, separator, and electrolyte, which is capable of storing electrical energy. When encased in a container and provided with electrical terminals, the cell is the basic "building block" of a battery. Although the capacity of the cell is determined by its size, the cell's voltage is strictly a function of the basic electrochemistry of the couple.

Cell Reversal

Reversing of polarity of terminals of a cell in a multi-cell battery due to over discharging.

Charge

Return of electrical energy to a battery.

Charge Acceptance

Willingness of a battery or cell to accept change. May be affected by cell temperature, charge rate and state of charge.

Charge Efficiency

Value obtained when the increase in dischargeable capacity of the battery is divided by the current input. A measure of charge acceptance. Also indicates

發(fā)電機依靠電壓調(diào)節(jié)器控制輸出電壓。電壓調(diào)節(jié)器檢測三相輸出電壓，以其平均值與要求的電壓值相比較。調(diào)節(jié)器從發(fā)電機內(nèi)部的輔助電源取得能量，通常是與主發(fā)電機同軸的小發(fā)電機，傳送DC電源給發(fā)電機轉(zhuǎn)子的磁場激勵線圈。線圈電流上升或下降，控制發(fā)電機定子線圈的旋轉(zhuǎn)磁場或稱為電動勢EMF的大小。定子線圈的磁通量決定發(fā)電機的輸出電壓。

發(fā)電機定子線圈的內(nèi)阻以Z表示，包括感性和阻性部分;由轉(zhuǎn)子勵磁線圈控制的發(fā)電機電動勢用交流電壓源以E表示。假設負載是純感性的，在向量圖中電流I滯后電壓U正好90°電相位角。如果負載是純阻性的，U和I的矢量將重合或同相。實際上多數(shù)負載介于純阻性和純感性之間。電流通過定子線圈引起的電壓降用電壓矢量I×Z表示。它實際上是兩個較小的電壓矢量之和，與I同相的電阻壓降和超前90°的電感壓降。在本例中，它恰好與U同相。因為電動勢必須等于發(fā)電機內(nèi)阻的電壓降和輸出電壓之和，即矢量E=U和I×Z的矢量和。電壓調(diào)節(jié)器改變E可以有效地控制電壓U。

現(xiàn)在考慮用純?nèi)菪载撦d代替純感性負載時，發(fā)電機的內(nèi)部情況會發(fā)生什么變化。這時的電流和感性負載時正好相反。電流I現(xiàn)在超前電壓矢量U，內(nèi)阻電壓降矢量I×Z，也正好反相。則U和I×Z的矢量和小于U。
