高壓配電室爲什麽不宜配備二氧化碳滅火器

來源：金鼎消防发布日期： 2021.10.21 作者：金鼎小編編輯：金鼎小編浏覽次數：

二氧化碳滅火系統作爲出現較早的氣體滅火系統，因其既可以全淹沒滅火，又可以局部滅火的特性，到現在依然屹立不倒。經常遇見有人詢問，爲什麽高壓配電室不宜配備二氧化碳滅火器？而是采用七氟丙烷滅火系統呢。金鼎消防就這個問題與您共同探討。

首先，二氧化碳滅火系統噴放時是霧狀液體，當電壓超過600V時，高壓電流會將二氧化碳擊穿，很可能會致使人員觸電，因此二氧化碳滅火器只能應用于低于600V配電房內，一旦超過600V，可使用幹粉滅火器或七氟丙烷滅火器。

其次，二氧化碳噴放過程中，由于液相和固態“幹冰”的快速氣化，防護區溫度急速下降，會産生一定程度的“冷激”、“冷淬”現象，對精密設備有一定的損壞。

除了上述兩種情況，二氧化碳濃度過高對人體有很大的危害，因二氧化碳泄漏導致的安全事故層出不窮，因此二氧化碳滅火器不建議用于封閉空間滅火。

金鼎消防是一家專注氣體滅火系統的生产厂家，公司生产的氣體滅火系統规格型号齐全，从业60余载，始终秉持着“以质量求生存，以创新求发展”的理念来服务客户。如果您需要咨询任何七氟丙烷滅火系統相關問題，歡迎撥打400-178-2088電話，或關注“湖南金鼎消防”微信公衆號，我們將不定期更新消防知識文章，期待您的光臨。

點擊展開

At this moment the steward rang the preparatory bell for dinner, and[Pg 52] the conversation ended. Half an hour later dinner was on the table, and the passengers sat down to it. Then there were fans on the list, and he went in pursuit of fans. He found them, and he thus had the opportunity of seeing the fan-makers at work. He found that there is a great variety in the fans which the Japanese make, and that the articles vary from prices which are astonishingly low to some which are dear in proportion. There is such a large trade in fans that he expected to find an extensive factory, employing hundreds of hands. He found, instead, that the fan-makers work on a very small scale, and that one person generally does only a small portion of the work, then turns it over to another, who does a little more, and so on. Certain low-priced fans are all finished in one shop; but with the high grades this is not the case, and, from first to last, a fan must pass through a good many hands. The fan-makers include women as well as men in their guild; and Frank thought it was by no means an unpleasant sight to see the women seated on the floor in front of low benches and gracefully handling the parts of the fan that was approaching completion in consequence of their manipulations. "I must not fail to tell you of a remarkable temple that we have seen; not that any are unworthy of mention, but this one is certainly very curious. It is known as the Temple of Rengenhoin, and contains one thousand idols of large size; then each idol in this lot is surrounded by several smaller ones, and there is one idol larger than all the rest. The[Pg 297] whole number is said to be 33,333. We did not count them to make sure that the estimate was correct, but I should think that there must be thirty thousand at least, so that a few odd thousands, more or less, would make no difference. The whole of the inside of the temple is full of them, and each figure is said to have a particular fable connected with it. The temple is nearly four hundred feet long, and is certainly a very fine building; and there is an artificial pond in front of it, which is covered with aquatic flowers in the season for them. There is a veranda that was used in olden times for a shooting-gallery for archery purposes; it is more than two hundred feet long, and there are records of some famous matches that have been shot there. The best on the books took place more than six hundred years ago, when one man is said to have hit the bull's-eye of the target 8,000 times out of 10,000, and another is reported to have done the same thing 8,133 times in 13,053. That was certainly good shooting, and I don't believe that it would be easy to find a bowman to-day who could equal it. He rescued his trousers from underneath the mattress. It was only recently that he had discovered this obvious substitute for a trouser press, and so added one more nuisance to existence. It was something else to be remembered. He grinned pleasantly at the thought of the circumstance which had brought about these careful habits. Rose Lomas liked him to look smart, and he had managed it somehow. There were plenty of dapper youths in Great Wymering, and Arthur had been astute enough to notice wherein he had differed from them, in the first stages of his courting. Early rebuffs had led him to perceive that the[Pg 69] eye of love rests primarily upon a promising exterior, and only afterwards discovers the interior qualities that justify a wise choice. Arthur had been spurned at first on account of a slovenliness that, to do him justice, was rather the result of personal conviction, however erring, than mere carelessness. He really had felt that it was a waste of life even to spend half an hour a month inside a barber's shop. Not only that, but the experience was far-reaching in its unpleasant consequences. You went into the shop feeling agreeably familiar with yourself, conscious of intense personality; and you came out a nonentity, smelling of bay-rum. The barber succeeded in transforming you from an individual brimming over with original reflections and impulses into a stranger without a distinctive notion in your head. The barber, in fact, was a Delilah in trousers; he ravished the locks from your head and bewitched you into the bargain. "I know. I remember that now. I said goodnight to the Countess--eh, eh, the Countess!--and there was a policeman outside talking to a man in evening dress. He said goodnight to me and I walked down the road. I don't recollect anything else." hard work. If nobody had been good enough in English, the committee 175 “Sorry he had all the trouble. We got the ‘phib’ engine going and I took Whiteside off on a little private matter in that.” The news was generally very encouraging. Every attack of the rebels had been repulsed, though our own loss had been heavy. But every man was needed. The rebel lines extended far beyond those of the union army in each direction, and still they had enough for heavy assaulting columns. Everybody in the neighborhood of Chattanooga had been ordered up, leaving only the meagerest possible guards for the trains and communications. "Don't be cross, Maria," pleaded Annabel. "I didn't know nothin' of it. You know I've been down to see the Robinses, and intended to stay till tomorrer, but something moved me to come home today, and I just happened to take this train. I really didn't know. Yet," and the instinctive rights of her womanhood and her future relations with Si asserted themselves to her own wonderment, "I had what the preachers call an inward promptin', which I felt it my dooty to obey, and I now think it came from God. You know I ought to be with Si as soon as anybody," and she hid her face in her hands in maidenly confusion. "Sure it can," she said. "But democracy is a civilized commodity, Johnny—in a primitive society it's a luxury the society can't afford. What guarantees have you got that the clan will elect the best possible leader? Or that, having elected him, they'll follow him along the best paths?" That year Reuben bought ten more acres of Boarzell, and limed them for oats. He felt that now he had strength to return to his first battle, and wring a grain crop out of that grudging soil. The new piece of ground abutted the Odiam lands on the Flightshot side, and he could see it from his window. Before going to bed at night, he would lean out and feast his eyes on it as it lay there softly covered in the dark, or glimmering in the faint star-dazzle of spring. Sometimes it seemed almost as if a breath came from it, a fragrance of sleep, and he would sit there inhaling it till Naomi peevishly begged him to shut the window and come to bed. Then in the mornings, when he woke according to healthy habit at five, he would sit up, and even from the bed he could see his land, waiting for him in the cold whiteness of dawn, silently calling him out to the freshness of its many dews. Rose's sobs burst forth afresh. Her friend ran up to her and took her in her arms, badly squeezing poor David, who became purple and entirely animal in his remonstrances.
