配電聚優柜的概念和配電聚優柜的大致分類

  1、配電聚優柜的基本概念

  通常電力的高低壓的區分方式是通過其額定電壓的大小,在1kV及以上的電壓等級被稱為中壓和高壓,而在1kV以下的電壓等級則被稱為低壓。

  低壓電力網是指配電變壓器的低壓側從直配發到電機母線。它主要由配電線路、配電裝置和用電設備組成。通過監測、計量、保護、控制電器到各個用戶受電設備組成的電力網絡。

  配電裝置是指由儀表、互感器、母線、開關電器按照一定的技術要求進行裝配,用來接收、分配和控制電能的設備。

  在已經制造好的屏架上進行電器元件安裝,這是配電裝置制作的重點,母線連接、二次配線、產品調試及產品包裝的全過程。

  2、分類

  一個低壓配電系統通常包括受電柜、饋電柜、無功功率補償柜等。在兩組變壓器供電時,相應地增加一個受電柜和一個母聯柜,控制的功能單元也就相應增多。

  低壓配電裝置又可分兩類:一類為抽屜式配電柜,像GCK、GCS, MNS;第二種為固定式配電柜,像GGD,。

  受電柜是配電系統的總開關,控制整個系統。

  饋電柜為直接對用戶的受電設備,控制各用電單元。

  低壓配電柜的型號有:BSL, BDL, PGL型。應急維修電源柜內裝備有充電電瓶,一旦出現停電或故障停電,還可用于局部的照明。
