低壓電器的定義與分類
低(di)壓電(dian)(dian)(dian)器(qi)是(shi)指在(zai)交流(liu)1000V或直流(liu)1500V以下的電(dian)(dian)(dian)路中使用的電(dian)(dian)(dian)器(qi)。它們是(shi)電(dian)(dian)(dian)力(li)(li)系統(tong)的重(zhong)要組(zu)成(cheng)部分，廣泛應用于工業、民用建筑以及(ji)基礎設施(shi)建設中。低(di)壓電(dian)(dian)(dian)器(qi)根據(ju)功能和用途(tu)可分為開(kai)關電(dian)(dian)(dian)器(qi)、保護電(dian)(dian)(dian)器(qi)、控制電(dian)(dian)(dian)器(qi)和連接電(dian)(dian)(dian)器(qi)等(deng)。這些(xie)電(dian)(dian)(dian)器(qi)在(zai)電(dian)(dian)(dian)力(li)(li)系統(tong)中承擔著(zhu)控制、保護、測量和連接等(deng)多(duo)種功能，確保電(dian)(dian)(dian)力(li)(li)系統(tong)的安全(quan)、可靠和高效(xiao)運行。
低壓電器的工作原理
