What is the CCA rating?
The cold cranking ampere (CCA) rating refers to the number of amperes a battery can support for 30 seconds at a temperature of 0°F until the battery voltage drops to 1.20 volts per cell, or 7.20 volts for a 12V battery. Thus, a 12V battery that carries a rating of 600 CCA ls us that the battery will provide 600 amperes for 30 seconds at 0°F before the voltage falls to 7.20V.
從誕生的世界上*個,除了可靠性,效率是一直追求的目標。從到現(xiàn)在效率超過的效率,行業(yè)專家該做些什么,讓如此高效?未來的改善空間,讓實現(xiàn)更高的效率?本文試圖對這一問題提出了一些看法。
為什么是有效的?
()可靠性要求
在產(chǎn)品的選擇,客戶首先關(guān)注的一定是可靠的。,效率越高意味著低熱量,根據(jù)阿列克絲耶夫娜新聞(阿倫尼烏斯理論),認為氣溫上升度理論、電子產(chǎn)品(如電容器、半導(dǎo)體裝置)生活的一半,減少熱量將減少設(shè)備的內(nèi)部溫度是一個重要的貢獻,從而提高設(shè)備本身的壽命。
當然,效率是*影響內(nèi)部溫度的主要因素,也要考慮機器本身的散熱設(shè)計。然而,效率成本低(往往意味著一個更好的散熱器或更大的散熱空間)、可靠性(故障點增加)或(不連續(xù)工作溫度度)以及犧牲,為了在可接受的范圍內(nèi),保護內(nèi)部的溫度。
()在開始國家節(jié)能減排政策
回應(yīng),工信部聯(lián)合五部委聯(lián)合下發(fā)“關(guān)于數(shù)據(jù)中心中國聯(lián)通部布局和施工指導(dǎo)”()號,新的數(shù)據(jù)中心低于,數(shù)據(jù)中心的原改造降低到以下;而系統(tǒng)主要由的能耗損失部分的數(shù)據(jù)中心,數(shù)據(jù)中心的能耗約占,數(shù)據(jù)中心實現(xiàn)低,必須選擇較高的的效率。圖顯示了不同類型的貢獻。
()為例,在一個中等規(guī)模的數(shù)據(jù)中心,節(jié)電
客戶需求,假設(shè)它負荷,個系列效率,系列效率,空調(diào)的能效比()。根據(jù)以上條件,由兩個造成的損失如表所示。
在一般情況下,的效率可以通過的電力成本增加一個百分點,得救了,我們可以看到大功率給企業(yè)帶來的效益是非??捎^的。
()認證門檻要求
應(yīng)對氣候變化,提高技術(shù)門檻,介紹世界上各種產(chǎn)品的節(jié)能認證標準,如中國“節(jié)能產(chǎn)品認證”、“能源之星”,兩者通過相關(guān)強制性認證的地方政府,不認證的產(chǎn)品不能進入名單。如英國的認證,需要超過滿負載效率,認證的產(chǎn)品,客戶可以申請的臺產(chǎn)品購買的*年減稅。這種節(jié)能認證,大大提高了效率高的產(chǎn)品的競爭力,同時也說明了高性能產(chǎn)品的重要性。
What is the marine cranking rating (MCA)?
The marine cranking ampere (MCA) rating refers to the number of amperes a battery can support for 30 seconds at a temperature of 32°F until the battery voltage drops to 1.20 volts per cell, or 7.20 volts for a 12V battery. Thus, a 12V battery that carries a MCA rating of 600 CCA ls us that the battery will provide 600 amperes for 30 seconds at 32°F before the voltage falls to 7.20V. Note that the MCA is sometimes referred to as the cranking amperes or CA.
What is the difference between MCA and CCA?
The marine cranking ampere (MCA) rating of a battery is very similar to the CCA rating; the only difference is that while the CCA is measured at a temperature of 0°F, the MCA is measured at 32°F. All other requirements are the same — the ampere draw is for 30 seconds and the end of discharge voltage in both cases is 1.20 volts per cell.
What is HCA rating?
The full form of HCA is hot cranking amperes. It is the same thing as the MCA or the CA or the CCA, except that the temperature at which the test is conducted is 80°F.

()負荷率對效率
負荷率的影響,對的效率影響很大。如圖所示,在正常情況下,的效率將隨著負載率的增加而增加,并且在負載率為時將達到較高的效率。結(jié)合圖的圖,不難得出以下結(jié)論:讓始終工作在率的負載范圍內(nèi),是提高效率的可行手段。然而,在實際的場景中,有以下幾個因素,使負載率不能在*負荷范圍內(nèi)工作,甚至低負荷率的存在,導(dǎo)致的效率很低。
*規(guī)劃
因為供配電系統(tǒng)是不容易的變換,房間將在未來到年業(yè)務(wù)發(fā)展規(guī)劃的考慮,往往需要在供配電系統(tǒng)的擴展能力計劃;圖給出了超前規(guī)劃減少的負載率。
冗余配置
為了保證供電及配電系統(tǒng)需要冗余的可靠性,常采用的配置,甚至利用的核心部分負荷或()的配置,以供在任何線路問題導(dǎo)致負載斷電的配電系統(tǒng);圖給出了冗余配置來降低系統(tǒng)負荷率。
機房的設(shè)計不能按負荷率設(shè)計。正常情況下,負載率不超過。
由于上述三個原因,正常情況下,的實際負載率小于,更高的冗余度,負荷率越低(見圖),一些房間的負載率將降低約。
損失組成
如何提高的損失由圖部分是輸入功率的zui終趨勢。
圖的黑暗部分是的輸出,也就是說,提供給負載能源;淺色部分是本身的損失,并zui終轉(zhuǎn)化為熱能或輻射。從圖可以看出,損耗不是線性增加,這是由于許多類型的損失。以下是空載損耗和負載損耗的分析,找出損耗的基本規(guī)律。
()空載損耗
從圖中可以看到,電源,該裝置的一部分始終處于工作狀態(tài),即使空載損失也是*的。這部分器件,zui大的損耗是電感,占,其次是的損耗和晶閘管驅(qū)動器和本身,兩者合計占到了左右,還有一些比較小的損耗,如放電電阻、電容電阻等。一般占zui大額定容量。
()滿負荷損失
圖全是損失分布可以看出,和二極管的損耗與空載損耗的增加比較明顯,空載從上升到;電感損耗占比略有下降,但仍占;損失略有增加,從上升到。其他人,如風(fēng)扇、監(jiān)測、控制面板等都有所下降。
