10KV開關(guān)柜控制原理課件

10KV開關(guān)櫃控制原理常開(動(dòng)合)按鈕電路符號(hào)SB1-1控制器件-按鈕常閉(動(dòng)斷)按鈕電路符號(hào)SB複合按鈕：常開按鈕和常閉按鈕做在一起。複合按鈕SB常開(動(dòng)合)按鈕電路符號(hào)SB常閉(動(dòng)斷)按鈕電路符號(hào)SB複合按鈕：常開按鈕和常閉按鈕做在一起。複合按鈕SB1-2控制器件-按鈕常開（動(dòng)合）觸頭常閉（動(dòng)斷）觸頭電路符號(hào)S和QF電路符號(hào)S和QF用作電路的限位保護(hù)、行程控制、自動(dòng)切換等。1-3控制器件-微動(dòng)和輔助開關(guān)結(jié)構(gòu)與按鈕類似，但其動(dòng)作要由機(jī)械撞擊。繼電器和接觸器的工作原理一樣。主要區(qū)別在於，接觸器的主觸頭可以通過(guò)大電流，而繼電器的觸頭只能通過(guò)小電流。所以，繼電器只能用於控制電路中。
