什麽(me) 是標準機櫃和非標準機櫃

　　What are standard and non-standard cabinets

很多工程級的設備的麵板寬度都采用19寸，所以19寸的機櫃常見的一種標準機櫃。

　　Many engineering grade equipment use a 19 inch panel width, so a 19 inch cabinet is a common standard cabinet.

　　標準機櫃的結構比較簡單，主要包括基本框架、內(nei) 部支撐係統、布線係統、通風係統。19寸標準機櫃外型有寬度、高度、深度三個(ge) 常規指標。雖然對於(yu) 19寸麵板設備安裝寬度為(wei) 465.1mm，但機櫃的物理寬度常見的產(chan) 品為(wei) 600mm和800mm兩(liang) 種。高度一般從(cong) 0.7M-2.4M，根據櫃內(nei) 設備的多少和統一格調而定，通常廠商可以定製特殊的高度，常見的成品19寸機櫃高度為(wei) 1.6M和2M。機櫃的深度一般從(cong) 400mm-800mm，根據櫃內(nei) 設備的尺寸而定，通常廠商也可以定製特殊深度的產(chan) 品，常見的成品19寸機櫃深度為(wei) 500mm、600mm、800mm。19寸標準機櫃內(nei) 設備安裝所占高度用一個(ge) 特殊單位"U"表示，1U=44.45mm。使用19寸標準機櫃的設備麵板一般都是按nU的規格製造。對於(yu) 一些非標準設備，大多可以通過附加適配檔板裝入19寸機箱並固定。

　　The structure of a standard cabinet is relatively simple, mainly including the basic framework, internal support system, wiring system, and ventilation system. The appearance of a 19 inch standard cabinet has three common indicators: width, height, and depth. Although the installation width for 19 inch panel equipment is 465.1mm, the common physical widths for cabinets are 600mm and 800mm. The height generally ranges from 0.7M to 2.4M, depending on the number of equipment inside the cabinet and the uniform style. Manufacturers can usually customize special heights, and common 19 inch cabinets have heights of 1.6M and 2M. The depth of the cabinet generally ranges from 400mm to 800mm, depending on the size of the equipment inside the cabinet. Manufacturers can also customize products with special depths. Common 19 inch cabinets have depths of 500mm, 600mm, and 800mm. The height occupied by the installation of equipment in a 19 inch standard cabinet is represented by a special unit "U", with 1U=44.45mm. Equipment panels using 19 inch standard cabinets are generally manufactured according to the specifications of 1U. For some non-standard devices, they can mostly be installed and fixed in a 19 inch chassis through an additional adapter board.
