電氣成套設(shè)備分享配電箱什么材料做的?

發(fā)布時間:2021-01-05 來源:http://m.xingthink.com/ 瀏覽量:

配電箱有木制和金屬制兩種,由于金屬配電箱防護(hù)等級要高一些,所以還是金屬的用的比較多。
There are two kinds of distribution box, wooden and metal. Because the protection level of metal distribution box is higher, it is still metal.
電氣成套設(shè)備配電箱按結(jié)構(gòu)特征和用處分類:
Distribution boxes of complete electrical equipment are classified according to their structural features and uses
(1)固定面板式開關(guān)柜,常稱開關(guān)板或配電屏。它是一種有面板遮攔的敞開式開關(guān)柜,正面有防護(hù)作用,反面和旁邊面仍能觸及帶電部分,防護(hù)等級低,只能用于對供電連續(xù)性和牢靠性要求較低的工礦企業(yè),作變電室會集供電用。
(1) Fixed panel switch cabinet, often called switch board or distribution panel. It is a kind of open switch cabinet with panel barrier. The front side has protective effect, while the back side and the side side can still touch the live parts. The protection level is low. It can only be used in industrial and mining enterprises with low requirements for continuity and reliability of power supply for centralized power supply in substation.
(2)防護(hù)式(即關(guān)閉式)開關(guān)柜,指除裝置面外,其它所有旁邊面都被關(guān)閉起來的一種低壓開關(guān)柜。這種柜子的開關(guān)、保護(hù)和監(jiān)測控制等電氣元件,均裝置在一個用鋼或絕緣材料制成的關(guān)閉外殼內(nèi),牢靠墻或離墻裝置。
(2) Protective (i.e. closed) switch cabinet refers to a kind of low-voltage switch cabinet in which all sides are closed except the device side. The switch, protection, monitoring control and other electrical components of the cabinet are installed in a closed shell made of steel or insulating material, which is firmly against the wall or away from the wall.
                       電氣成套
柜內(nèi)每條回路之間可以不加隔離辦法,也可以選用接地的金屬板或絕緣板進(jìn)行隔離。通常門與主開關(guān)操作有機械聯(lián)鎖。配電箱種類別的還有防護(hù)式臺型開關(guān)柜(即控制臺),面板上裝有控制、丈量、信號等電器。防護(hù)式開關(guān)柜主要用作工藝現(xiàn)場的配電裝置。
Each circuit in the cabinet can be isolated without isolation method, or grounded metal plate or insulating plate can be selected for isolation. Generally, the door is mechanically interlocked with the main switch. There are other types of distribution box, such as protective platform type switch cabinet (console), which is equipped with control, measurement, signal and other electrical appliances. The protective switch cabinet is mainly used as the power distribution device in the process site.
(3)抽屜式開關(guān)柜。這類開關(guān)柜選用鋼板制成關(guān)閉外殼,進(jìn)出線回路的電器元件都裝置在可抽出的抽屜中,構(gòu)成能完成某一類供電任務(wù)的功用單元。功用單元與母線或電纜之間,用接地的金屬板或塑料制成的功用板隔開,構(gòu)成母線、功用單元和電纜三個區(qū)域。每個功用單元之間也有隔離辦法。
(3) Drawer type switch cabinet. This kind of switch cabinet is made of steel plate, and the electrical components in and out of the circuit are installed in the extractable drawer, forming a functional unit that can complete a certain type of power supply task. The function unit and bus or cable are separated by grounded metal plate or plastic function plate to form three areas of bus, function unit and cable. There are also isolation methods between each functional unit.
