帶你了解自耦變壓器降壓啓動原理

返回列表 來源：发布日期： 2020.12.26

我們都知道自耦降壓控制櫃具有過載、短路、缺相保護以及泵體漏水，電機高溫及漏電等多種保護功能及齊全的狀態顯示，采用自耦變壓器降壓啓動方式，降低對電網的沖擊，並具備單泵及多泵控制工作模式。那麽自耦變壓器降壓啓動原理你知道嗎？今天我們來了解一下。

帶你了解自耦變壓器降壓啓動原理

選用自耦變壓器能夠完成降壓啓動。其工作基本原理以下：

啓動

用接上短路线的KM1，做为自耦变压器的星点，用KM2做为自耦变压器的开关电源键入电源开关。啓動，根据KM1接入自耦变压器的星点，根据KM2接入自耦变压器的开关电源，啓動刚开始。

運作

啓動后历经一段时间，根据KM2先断开自耦变压器的开关电源，根据KM1后断开自耦变压器的星点，才可以根据KM3连接運作开关电源

控制回路

要保證KM1、KM2、KM3井然有序地資金投入和摘除，就需要搞好控制回路的變換次序。
要采用的元器件有：啓動按钮一个；终止按钮一个；交流接触器KM1、KM2、KM3三个；廷时用的时间控制器一个；电动机过电流热敏电阻汽车继电器一个。控制回路的工作程序流程有四步：初始情况；啓動情况；運作情况；终止情况。从而可获得以下的元器件工作状态表以下表所显示。

以上就是今天的分享了，如果您對我們的自耦降壓控制感興趣或者想了解更多詳細信息，歡迎點擊我們的在線客服與技術員咨詢，或者直接撥打技術員電話咨詢，我們期待您的來電與合作！

‘Yours faithfully, "We went along the street, stopping now and then to look at something, and in a little while we came to a tea-house which stood in the middle of a pond of water. The house was rather pretty, and the balconies around it were nice, but you should have seen the water. It was covered with a green scum, such as you may see on a stagnant pool anywhere in the world, and the odor from it was anything but sweet. Fred said it was the same water that was let into the pool when they first made it. The guide says the house is a hundred years old, and I should think the water was quite as old as the house; or perhaps it is some second-hand water that they bought cheap, and if so it may be very ancient. We went into the house and sat down to take some tea. They gave us some tea-leaves, on which they poured hot water, and then covered the cup over for a minute or two. Each of us had his portion of tea separate from all the others. The tea was steeped in the cup, and when we wanted more we poured hot water on again. Then they brought little cakes and melon-seeds, with salt to eat with the seeds. Our guide took some of the seeds, and we ate one or two each to see how they tasted. I can't recommend them, and don't think there is any danger they will ever be introduced into the United States as a regular article of diet. "Oh, yes there is; he goes by various names, but one of them is Ned Ferry. Sergeant, we'll kick together; now!"--Bang! 34 [Pg 214] The Deacon started to protest, but the man was in a hurry, and almost pulled him off, and slapped his own saddle on in a flash. "It's right. It's all right. It's God's ways," said the mother. "You've bin among rough men so long that you don't know how to talk to real ladies." "Mister Billings," said he, sternly, "what was the General's orders about wearin' anything military?" "Goin' to be a full attendance at the services this evenin'," he muttered to himself. "But the more the merrier. It'll insure a goodly number at the mourner's bench when we make the call for the unconverted." Si announced, as he shoved back from the table: "Harry—will you—will you take this basin of cream to your mother?" Strange to say, Harry, who had paid little attention to the earlier babies, seemed drawn to this one. He would hang round Naomi when she had her in her lap, and sometimes gingerly put out a hand and stroke the child's limbs. Naomi could not bear that he should touch her; but he amused Fanny, so she tolerated him. He had fallen into the habit of many half-witted[Pg 92] people and occasionally made strange faces, which though repulsive to everyone else, filled Fanny with hilarious delight. Indeed they were the first thing she "noticed." "Welcome," she said, and laughed. He sat down by the open window, leaning his elbow on the sill. The night was as soft as honey, and dark as a bowl of wine. The stars were scattered and dim, the moon had dipped into a belt of fogs, the fields were bloomed with darkness and sleep. The ridge of Boarzell was just visible under the Dog Star—the lump of firs stood motionless, for the wind had dropped, and not even a whisper from the orchard proclaimed its sleeping place. "Besides, it ?un't likely as we'd do as well fur ourselves as Richard. We've no Miss Bardon to trouble about us—reckon we'd come to grief like Albert." HoME 亚洲强奸乱伦av天堂网ENTER NUMBET 008www.cpov.com.cn
