          控制回路隔室與功能單元隔室之間用阻燃型聚胺脂發(fā)泡塑料模制罩殼分隔。
          The control circuit compartment and the functional unit compartment are separated by a flame-retardant polyurethane foam plastic molded cover.
          左邊的功能單元隔室與右邊的電纜隔室之間用鋼板分隔。
          The functional unit compartment on the left is separated from the cable compartment on the right by steel plates.
          抽出式電動(dòng)控制中心和小電流的動(dòng)力配電中心(以下簡(jiǎn)稱(chēng)為抽出式
          Drawout electric control center and small current power distribution center (hereinafter referred to as drawout type)
          MNS低壓抽屜柜
          抽出式MCC柜內分成三個(gè)隔室,即柜后部的水平母線(xiàn)隔室,柜前部左邊的功能單元隔室,柜前部右邊的電纜隔室。水平母線(xiàn)隔室與功能單元隔室之間用阻燃型發(fā)泡塑料制成的功能板分隔,電纜隔室與水平母線(xiàn)隔室、功能單元隔室之間用鋼板分隔。
          The withdrawable MCC cabinet is divided into three compartments, namely the horizontal busbar compartment at the rear of the cabinet, the functional unit compartment on the left front of the cabinet, and the cable compartment on the right front of the cabinet. The horizontal busbar compartment and functional unit compartment are separated by functional boards made of flame-retardant foam plastic, and the cable compartment is separated from the horizontal busbar compartment and functional unit compartment by steel plates.
          可移式電動(dòng)機控制中心和小電流動(dòng)力配電中心(以下可簡(jiǎn)稱(chēng)為可移式
          Portable motor control center and small current power distribution center (hereinafter referred to as portable)
          可移式MCC的框體結構特征同2.1和2.2。
          The frame structure characteristics of the movable MCC are the same as those in 2.1 and 2.2.
          功能單元設計成可移式結構,功能單元與垂直母線(xiàn)的連接,采用一次隔離觸頭,即使與其連接的電路是帶電的,也可以從設備中完整地取出和放回該功能單元,另一端為固定式結構。
          The functional unit is designed as a movable structure, and the connection between the functional unit and the vertical busbar adopts a primary isolation contact. Even if the circuit connected to it is live, the functional unit can be completely removed and placed back from the equipment, and the other end is a fixed structure.
          可移式MCC的功能單元分為8E/4,8E/2,8E,16E,24E,32E和40E。功能單元隔室總高度也是72E。
          The functional units of portable MCC are divided into 8E/4, 8E/2, 8E, 16E, 24E, 32E, and 40E. The total height of the functional unit compartment is also 72E.
          母線(xiàn)系統
          Bus system
          水平母線(xiàn)安裝于柜后獨立的母線(xiàn)隔室中,它有二個(gè)可選擇的安裝位置,即柜高的三分之一或三分之二處,母線(xiàn)可按需要裝于上部或下部,也可以上下二組同時(shí)安裝,二組母線(xiàn)可以單獨使用,也可以并聯(lián)使用。每相母線(xiàn)由2根或8根母線(xiàn)并聯(lián),母排截面有10×32×2,10×60×2,10×80×2,10×60×4,10×80×2×2和10×60×4×2 六種。
          The horizontal busbar is installed in an independent busbar compartment behind the cabinet, with two optional installation positions, namely one-third or two-thirds of the cabinet height. The busbar can be installed on the upper or lower part as needed, or two sets of upper and lower buses can be installed simultaneously. The two sets of busbars can be used separately or in parallel. Each phase of the busbar is connected in parallel with 2 or 8 busbars, with a busbar cross-section of 10 × thirty-two × 2,10 × sixty × 2,10 × eighty × 2,10 × sixty × 4,10 × eighty × two × 2 and 10 × sixty × four × Two or six types.
          垂直母線(xiàn)
          Vertical busbar
          垂直母線(xiàn)50×30×5的"L"型銅母線(xiàn),它被嵌裝于用阻燃型塑料制造的功能板中。帶電部分的防護達IP20。
          Vertical busbar 50 × thirty × The "L" type copper busbar of 5 is embedded in a functional board made of flame-retardant plastic. The protection of live parts reaches IP20.
          中性母線(xiàn)(N線(xiàn))和中性保護母線(xiàn)(PE線(xiàn)或PEN線(xiàn))中性母線(xiàn)和中性保護母線(xiàn)平行地安裝在功能單元隔室的下部和垂直安裝在電纜室中,N線(xiàn)與PE線(xiàn)之間如用絕緣子相隔,則N線(xiàn)與PE線(xiàn)分別使用,二者之間如用導體連接,即成PEN線(xiàn)。
          The neutral busbar (N line) and neutral protection busbar (PE line or PEN line) are installed parallel to the lower part of the functional unit compartment and vertically in the cable compartment. If insulators are used to separate the N line and PE line, they are used separately. If conductors are used to connect the two, they become PEN lines.
