配電(dian)柜pv和sv分別代表什么意思？PV通常(chang)(chang)就(jiu)是我們(men)(men)(men)通常(chang)(chang)所說(shuo)的(de)(de)(de)實際測量(liang)值(zhi)(zhi)(zhi)（由各種測量(liang)探(tan)頭：溫度(du)，壓(ya)(ya)力(li)，流(liu)量(liang)，電(dian)流(liu)，電(dian)壓(ya)(ya)等(deng)(deng)等(deng)(deng)）。SV通常(chang)(chang)就(jiu)是我們(men)(men)(men)說(shuo)的(de)(de)(de)電(dian)氣元件的(de)(de)(de)設定值(zhi)(zhi)(zhi)（通常(chang)(chang)我們(men)(men)(men)設定多少溫度(du)，壓(ya)(ya)力(li)，流(liu)量(liang)，電(dian)壓(ya)(ya)，電(dian)流(liu)等(deng)(deng)等(deng)(deng)），SV有時也會(hui)寫成SP。MV通常(chang)(chang)就(jiu)是我們(men)(men)(men)說(shuo)的(de)(de)(de)手動輸(shu)出(chu)值(zhi)(zhi)(zhi)（根據測量(liang)值(zhi)(zhi)(zhi)調(diao)節(jie)輸(shu)出(chu)）。控制(zhi)器一般都是把PV測量(liang)值(zhi)(zhi)(zhi)和SV整定值(zhi)(zhi)(zhi)進行(xing)比(bi)對之(zhi)后再輸(shu)出(chu)的(de)(de)(de)MV值(zhi)(zhi)(zhi)，進而控制(zhi)執行(xing)器進行(xing)操作。例如：調(diao)節(jie)輸(shu)出(chu)電(dian)流(liu)，電(dian)壓(ya)(ya)，調(diao)整閥開度(du)等(deng)(deng)等(deng)(deng)。
