          低壓開(kāi)關(guān)柜的分類(lèi)及特點(diǎn)介紹

          發(fā)布時(shí)間:2023-08-08 來(lái)源:http://www.lfnanning.cn/ 瀏覽量:

          低壓開(kāi)關(guān)柜分類(lèi)從兩個(gè)方面進(jìn)行講解:1.從結構方式上分;2.從連接方式上分,下面小編來(lái)詳細介紹一下吧!從結構方式上分:固定式、抽出式。
          The classification of low-voltage switchgear is explained from two aspects: 1. From the perspective of structural mode; 2. From the perspective of connection methods, the following editor will provide a detailed introduction! From the perspective of structural mode, it can be divided into fixed type and withdrawable type.
          1、固定式:
          1. Fixed:
          能滿(mǎn)足各電器元件可靠地固定于柜體中確定的位置。柜體外形一般為立方體,如屏式、箱式等,也有棱臺體如臺式等。這種柜有單列,也有排列。
          It can ensure that all electrical components are reliably fixed in the designated position in the cabinet. The appearance of the cabinet is generally cubic, such as screen type, box type, etc., and there are also prismatic platforms such as desktop. This type of cabinet has a single row and also an arrangement.
          2、抽出式:
          2. Withdrawal type:
          抽出式是由固定的柜體和裝有開(kāi)關(guān)等主要電器元件的可移裝置部分組成,可移部分移換時(shí)要輕便,移入后定位要可靠,并且相同類(lèi)型和規格的抽屜能可靠互換,抽出式中的柜體部分加工方法基本和固定式中柜體相似。

          The withdrawable type is composed of a fixed cabinet body and a movable device part equipped with main electrical components such as switches. The movable part should be light and reliable when moved in, and drawers of the same type and specification can be reliably interchanged. The processing method of the cabinet body in the withdrawable type is basically similar to that in the fixed type.
          但由于互換要求,柜體的精度必須提高,結構的相關(guān)部分要有足夠的調整量,于可移裝置部分,要既能移換,又要可靠地承裝主要元件,所以要有較高的機械強度和較高的精度,其相關(guān)部分還要有足夠的調整量。
          However, due to the requirements for interchangeability, the accuracy of the cabinet body must be improved, and the relevant parts of the structure must have sufficient adjustment. As for the movable device part, it must be able to be replaced while reliably supporting the main components. Therefore, it must have high mechanical strength and accuracy, and the relevant parts must also have sufficient adjustment.
          從連接方式上分:焊接式、緊固件連接
          From the connection method, it can be divided into welding type and fastener connection
          1、焊接式:
          1. Welding type:
          它的優(yōu)點(diǎn)是加工方便、堅固可靠;缺點(diǎn)是誤差大、易變形、難調整、欠美觀(guān),而且工件一般不能預鍍。
          Its advantages are convenient processing, sturdy and reliable; The disadvantages are large errors, easy deformation, difficulty in adjustment, and lack of aesthetics, and the workpiece generally cannot be pre plated.
          2、緊固件連接:
          2. Fastener connection:
          它的優(yōu)點(diǎn)是適于工件預鍍,易變化調節,易美化處理,零部件可標準化設計,并可預生產(chǎn)庫存,構架外形尺寸誤差小。缺點(diǎn)是不如焊接堅固,要求零部件的精度高,加工成本相對上升。緊固件一般都為標準件,其種類(lèi)主要有常規的螺釘、螺母和鉚釘、拉鉚釘,以及預緊而可微調的卡箍螺母和預緊的拉固螺母,還有自攻螺釘等。也有專(zhuān)用緊固螺釘(如國外引進(jìn)的低壓柜大多用專(zhuān)用緊固螺釘)。
          Its advantages are suitable for pre plating of workpieces, easy to change and adjust, easy to beautify, standardized design of components, and pre production inventory. The overall size error of the structure is small. The disadvantage is that it is not as sturdy as welding, requiring high precision of components and relatively high processing costs. Fasteners are generally standard components, mainly including conventional screws, nuts and rivets, pull rivets, pre tensioned and adjustable clamp nuts and pre tensioned pull nuts, as well as self tapping screws. There are also special fastening screws (such as most low-voltage cabinets imported from abroad use special fastening screws).
