水(shui)泵變(bian)(bian)頻(pin)(pin)(pin)控(kong)制柜(ju)(ju)連接(jie)(jie)著(zhu)進線電源，可以幫助變(bian)(bian)頻(pin)(pin)(pin)控(kong)制柜(ju)(ju)完成電路(lu)(lu)的(de)通斷操作，并能(neng)夠在電路(lu)(lu)和(he)變(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)出現短路(lu)(lu)或過載時(shi)提供(gong)保護(hu)。變(bian)(bian)頻(pin)(pin)(pin)水(shui)泵控(kong)制柜(ju)(ju)系統通過測到(dao)的(de)管道壓力，經(jing)變(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)系統內置的(de)PID調(diao)節(jie)器(qi)(qi)(qi)運算(suan)，調(diao)節(jie)輸出頻(pin)(pin)(pin)率，然后實現管網的(de)恒壓供(gong)水(shui)。變(bian)(bian)頻(pin)(pin)(pin)水(shui)泵控(kong)制柜(ju)(ju)主(zhu)要由變(bian)(bian)頻(pin)(pin)(pin)控(kong)制箱，壓力傳感器(qi)(qi)(qi)，水(shui)泵等(deng)組成。變(bian)(bian)頻(pin)(pin)(pin)控(kong)制柜(ju)(ju)由斷路(lu)(lu)器(qi)(qi)(qi)，變(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)，接(jie)(jie)觸(chu)器(qi)(qi)(qi)，中間繼電器(qi)(qi)(qi)，PLC的(de)等(deng)組成。

排(pai)水(shui)泵(beng)操(cao)(cao)(cao)控(kong)(kong)柜。排(pai)水(shui)泵(beng)操(cao)(cao)(cao)控(kong)(kong)柜可(ke)操(cao)(cao)(cao)控(kong)(kong)一(yi)臺或(huo)多(duo)臺水(shui)泵(beng)，通常是一(yi)用(yong)一(yi)備，水(shui)泵(beng)變(bian)頻(pin)控(kong)(kong)制(zhi)(zhi)柜批(pi)發，互為備用(yong)，作業(ye)泵(beng)毛病時備用(yong)泵(beng)主動投入。由單液位或(huo)多(duo)液位操(cao)(cao)(cao)控(kong)(kong)還能(neng)夠(gou)長(chang)途操(cao)(cao)(cao)控(kong)(kong)。變(bian)頻(pin)控(kong)(kong)制(zhi)(zhi)柜是用(yong)于50Hz、網絡電(dian)壓380V、容量從0.75~630KW三相異步電(dian)機的(de)調速及運(yun)(yun)轉使用(yong)。變(bian)頻(pin)控(kong)(kong)制(zhi)(zhi)柜的(de)特點：運(yun)(yun)行(xing)(xing)成本降低(di)(di)(di)。傳統電(dian)機的(de)運(yun)(yun)行(xing)(xing)成本由三項組(zu)成：初(chu)始采購(gou)成本、維護(hu)成本和(he)能(neng)源成本。其(qi)中能(neng)源成本大(da)(da)約占電(dian)機運(yun)(yun)行(xing)(xing)成本的(de)77%。通過能(neng)源成本降低(di)(di)(di)44.3%，電(dian)泵(beng)變(bian)頻(pin)控(kong)(kong)制(zhi)(zhi)柜，再加上(shang)變(bian)頻(pin)起動后對設備的(de)沖(chong)擊減少(shao)，維護(hu)和(he)維修(xiu)量也跟隨(sui)降低(di)(di)(di)，所以運(yun)(yun)行(xing)(xing)成本將大(da)(da)大(da)(da)降低(di)(di)(di)。
