機房供配電系統是機房的血管，只有安全、穩定的供配電系統才能保證機房設備的正常運行。

機房供配電系統

1.機房供配電系統--常識

1.1、機房供配電系統應爲380V/200V、50HZ，計算機供電質量達到a級。

1.2、機房內用電設備的供電電源均爲三相五線制和單相三線制

1.3、机房用电设备、配电线路装设过流过载两段保护，同时配电系统各级之间有选择性地配合，配电以放射式向用电设备供电；

1.4、機房配電系統使用的電纜均爲阻燃聚氯乙烯絕緣電纜和阻燃交聯電纜，鋪設鍍鋅鐵槽SR和鍍鋅鋼管SC和金屬軟管CP

1.5、機房配電設備與消防系統聯動

2、機房供配電系統--注意的地方

供配电方式为双路供电系统添加UPS电源和柴油发电机设备，单独供电空调系统和其他电气设备，避免空调系统启动和停止对重要电气设备的干扰。供电系统的负载服务器的功率、单台服务器功率、UPS总功率。

3、機房供配電系統--配電盤

3.1、選擇自動空氣開關。

3.2、配電盤的供電回路數，充分考慮設備的使用和設備的擴展。

3.3、設置緊急開關，機房發生重大事故或火災時，可立即切斷電腦系統的電源。

3.4、配電櫃安裝電壓表，查驗供電計算機的電源電壓，並安裝轉換開關能夠隨時查驗三相電壓的不平衡狀況。

3.5、配電櫃安裝電流表，檢查供電計算機的電源電流。並設置三塊電流表，以隨時可檢查三相電流的不平衡情況。

3.6、各路電源設有指示燈，指示通斷。

3.7、裝有過電流報警、接地電阻報警、漏電流報警、頻率報警等報警系統。

4、機房供配電系統--插座。

室內用電插座分爲UPS插座和市電插座兩種。機房各工作室留有備用插座，設置在牆下修理設備時使用。

5、機房供配電系統--電線電纜。

機械室內的電線電纜除了具有相應的負荷流量外，還必須考慮電纜的阻燃特性等要求。

選擇電線電纜時，主要考慮以下因素:

5.1、電纜型式：機房內所用電纜全部采用優質阻燃電纜。

5.2、導線截面選擇:根據負荷大小、電壓損失允許、導線長時間允許溫度上升和導線機械強度等因素進行選擇，負荷流量具有備用能力，爲將來的擴張做准備。

5.3、機房內所有電纜穿鍍鋅金屬線槽或鍍鋅鋼管敷設于地板下或天花內。

5.4、爲了方便檢查線路，在各回路電纜的兩端標記。

6、機房供配電系統--線路鋪設。

6.1、機房內的所有動力電纜都鋪設在可動地板下或天花板上。

6.2、提供計算機設備的電源線從UPS輸出配電箱供電到計算機設備專用分支配電屏幕，然後從分支配電屏幕送到各計算機設備的供電插座。

6.3、天花照明電源線在天花板上穿鍍鋅金屬線槽或鍍鋅鋼管鋪設，在附近用軟管鋪設到照明器具。

6.4、一般插座和照明开关电缆通过镀锌金属线槽敷设，再经镀锌钢管敷设至各固定插座和开关。

6.5、爲防止漏電危及人身安全，並防止電磁幹擾，機房內所有金屬線管、線槽、電氣設備外殼等不帶電的金屬部分都可靠接地。

機房供配電系統

7、機房供配電系統--備用電源。

一般采用柴油发电机组，作为特别重要的负荷应急电源，应满足的运行方式是，正常情况下，柴油发电机组应始终处于发动状态，两路市电停止时，机组应立即启动，具有100%负荷的能力。任何市电恢复时，单元应自动退出运行，延迟停止，恢复市电供电。机组与电力系统间应有防止并列运行的连锁装置。柴油发电机组的容量应按照用电负荷的分类来确定，因为有的负荷需要很大的启动功率，如空调电动机，这就需要合理选择发电机组容量，以避免过大的启动电压降，一般根据上述用电负荷总功率的2.5倍来计算。

The light breakfast was taken, and the adventurers moved on. At each step the way grew more and more difficult. Every mile was steeper than its predecessor, and in many instances it was rougher. The rarefaction of the air increased, and rendered the work of breathing more and more severe. The travellers panted like frightened deer, and their lungs seemed to gain little relief from the rest that the Doctor and his young friends were compelled to take at frequent intervals. The last of the huts of refuge was passed, and it seemed only a short distance to the summit. But it required more than an hour's effort to accomplish this final stage. The boys refused all offers of assistance, and struggled manfully on; but Doctor Branson was less confident of his powers, and was glad of the aid of the strong-limbed and strong-handed yamabooshees. All were glad enough to stand on the summit and gaze into the deep gulf of the crater, while their brows were cooled by the clear breezes from the Pacific. They were at the top of Fusiyama, 14,000 feet above the level of the ocean that lay so far below them, eighty miles from their starting-point at Yokohama, and their vision swept an area of the surface of the earth nearly two hundred miles in diameter. East and south lay the broad ocean. West and north was the wondrous land of Japan, a carpet of billowy green, roughened here and there with wooded hills and small mountains, indented with bays and with silver threads of rivers meandering through it. It was a picture of marvellous beauty which no pen can describe. "I should like to know what you make of them," said Lawrence. "Ah well, be you a Fleming?" We have now to see how, granting Epicurus his conception of painlessness as the supreme good, he proceeds to evolve from it a whole ethical, theological, and physical system. For reasons already mentioned, the ethical development must be studied first. We shall therefore begin with an analysis of the particular virtues. Temperance, as the great self-regarding duty, obviously takes precedence of the others. In dealing with this branch of his subject, there was nothing to prevent Epicurus from profiting by the labours of his predecessors, and more especially of the naturalistic school from Prodicus down. So far as moderation is concerned, there need be little difference between a theory of conduct based exclusively on the interests of the individual, and a theory which regards him chiefly as a portion of some larger whole. Accordingly, we find that our philosopher, in his praises of frugality, closely approximated to the Cynic and Stoic standards—so much so, indeed, that his expressions on the subject are repeatedly quoted by Seneca as the best that could be found. Perhaps the Roman moralist valued them less for their own sake than as being, to some extent, the admissions of an opponent. But, in truth, he was only reclaiming what the principles of his own sect had originally inspired. To be content with the barest necessaries was a part of that Nature-worship against which Greek humanism, with its hedonistic and idealistic offshoots, had begun by vigorously protesting. Hence many passages in Lucretius express exactly the same sentiments as those which are most characteristic of Latin literature at a time when it is completely dominated by Stoic influences. J. A. “I thought I saw—but it’s gone!” Larry retorted, lowering his voice also. “The Everdail Emeralds!” Larry repeated the phrase sharply. “Why, Jeff! I’ve read a newspaper story about them, in a Sunday supplement. That’s the matched set of thirty emeralds——” "You are not fit to go," Felipa said resignedly, "but that doesn't matter, of course." Dr. Arbuthnot, a great friend of Pope and Swift, was also one of the ablest prose writers, "The Memoirs of Martinus Scriblerus," published in Pope's and Swift's works, and the political satire of "John Bull," a masterly performance, being attributed to him. "Blank your Captain," roared the voice; "I'm no Captain." "What's that?" said the Deacon, rousing to interest, but carefully putting his thumb down to mark the place where he left off. "O, open it, Maria," groaned Si, "and you'll likely find his name writ somewhere inside." "I do not understand your one thing or your other thing;" answered Turner—"but I know this, that we have paid the tax, and that we will pay it no more—but as for touching what belongs to the London folks—I'll tell you what, if we do set fire to London, by St. Nicholas! if I see my own son Tom taking a penny's worth, I will fling him into the flames!"
