电气成套设备分享配电箱什么材料做的?

发布时间:2021-01-05 来源:http://www.tongyuhengcheng.com/ 浏览量:

配电箱有木制和金属制两种,由于金属配电箱防护等级要高一些,所以还是金属的用的比较多。
There are two kinds of distribution box, wooden and metal. Because the protection level of metal distribution box is higher, it is still metal.
电气成套设备配电箱按结构特征和用处分类:
Distribution boxes of complete electrical equipment are classified according to their structural features and uses
(1)固定面板式开关柜,常称开关板或配电屏。它是一种有面板遮拦的敞开式开关柜,正面有防护作用,反面和旁边面仍能触及带电部分,防护等级低,只能用于对供电连续性和牢靠性要求较低的工矿企业,作变电室会集供电用。
(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)防护式(即关闭式)开关柜,指除装置面外,其它所有旁边面都被关闭起来的一种低压开关柜。这种柜子的开关、保护和监测控制等电气元件,均装置在一个用钢或绝缘材料制成的关闭外壳内,牢靠墙或离墙装置。
(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.

柜内每条回路之间可以不加隔离办法,也可以选用接地的金属板或绝缘板进行隔离。通常门与主开关操作有机械联锁。配电箱种类别的还有防护式台型开关柜(即控制台),面板上装有控制、丈量、信号等电器。防护式开关柜主要用作工艺现场的配电装置。
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)抽屉式开关柜。这类开关柜选用钢板制成关闭外壳,进出线回路的电器元件都装置在可抽出的抽屉中,构成能完成某一类供电任务的功用单元。功用单元与母线或电缆之间,用接地的金属板或塑料制成的功用板隔开,构成母线、功用单元和电缆三个区域。每个功用单元之间也有隔离办法。
(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.
