明泰(tai)電(dian)(dian)氣(qi)（蘇州）有(you)限公司是正(zheng)泰(tai)集團在(zai)蘇州地區一家授權的經銷企業(ye)，連續十年銷量居正(zheng)泰(tai)營(ying)銷網絡(luo)名，公司主要經營(ying)“正(zheng)泰(tai)”牌配電(dian)(dian)電(dian)(dian)器(qi)(qi)(qi)(qi)、控制電(dian)(dian)器(qi)(qi)(qi)(qi)、終端電(dian)(dian)器(qi)(qi)(qi)(qi)、電(dian)(dian)源電(dian)(dian)器(qi)(qi)(qi)(qi)、電(dian)(dian)力電(dian)(dian)子、儀(yi)器(qi)(qi)(qi)(qi)儀(yi)表、建(jian)筑電(dian)(dian)器(qi)(qi)(qi)(qi)、高壓電(dian)(dian)器(qi)(qi)(qi)(qi)及成套設備。

變頻器應用領域：

運(yun)送(song)車(che)類負載(zai)　　煤(mei)礦的原(yuan)煤(mei)裝運(yun)車(che)或鋼(gang)(gang)廠的鋼(gang)(gang)水運(yun)送(song)車(che)等采(cai)用變頻技(ji)術效果很好。起停快速(su)，過載(zai)能力(li)強，正(zheng)反(fan)轉靈(ling)活(huo)，達到煤(mei)面平整、重量(liang)正(zheng)確（不多裝或少(shao)裝），基(ji)本(ben)上不需要人(ren)工(gong)操作，提(ti)高(gao)了原(yuan)煤(mei)生產效率，常州西門子V120變頻器，節(jie)約了電能。

明(ming)泰電(dian)(dian)(dian)氣（蘇(su)州）有(you)限公司是正泰集(ji)團在蘇(su)州地區一家(jia)授權(quan)的經(jing)銷(xiao)企業，連續十年銷(xiao)量居正泰營銷(xiao)網絡名，公司主要經(jing)營“正泰”牌配電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)(qi)、控制(zhi)電(dian)(dian)(dian)器(qi)(qi)、終端(duan)電(dian)(dian)(dian)器(qi)(qi)、電(dian)(dian)(dian)源電(dian)(dian)(dian)器(qi)(qi)、電(dian)(dian)(dian)力電(dian)(dian)(dian)子、儀器(qi)(qi)儀表、建筑電(dian)(dian)(dian)器(qi)(qi)、高壓電(dian)(dian)(dian)器(qi)(qi)及成套設備。

過(guo)流(liu)指電(dian)(dian)機(ji)（變頻器輸出）的(de)電(dian)(dian)流(liu)超過(guo)規定(ding)值；過(guo)載指電(dian)(dian)機(ji)的(de)負載超過(guo)電(dian)(dian)機(ji)的(de)額定(ding)功率。過(guo)流(liu)和(he)過(guo)載的(de)產生(sheng)主要(yao)原因都是電(dian)(dian)機(ji)超載。之所以要(yao)分為兩個指標，原因在于：

1.兩者保(bao)護的(de)對(dui)象不同。過電流(liu)主(zhu)(zhu)要用于保(bao)護變(bian)頻器，而過載(zai)主(zhu)(zhu)要用于保(bao)擴電動機。因為變(bian)頻器的(de)容(rong)量通(tong)常會比電動機的(de)容(rong)量加(jia)大一(yi)些。在這(zhe)種(zhong)情況(kuang)下(xia)，電動機過載(zai)時，變(bian)頻器不一(yi)定過電流(liu)。

2.電流(liu)(liu)(liu)的(de)(de)(de)變(bian)化(hua)(hua)(hua)率不同(tong)。過載(zai)(zai)保護發生(sheng)(sheng)在生(sheng)(sheng)產(chan)機械的(de)(de)(de)工作過程中，西門(men)子V120變(bian)頻器生(sheng)(sheng)產(chan)廠家，電流(liu)(liu)(liu)的(de)(de)(de)變(bian)化(hua)(hua)(hua)率通常(chang)較小：除了過載(zai)(zai)以外的(de)(de)(de)其它過電流(liu)(liu)(liu)，常(chang)常(chang)帶有突發性，電流(liu)(liu)(liu)的(de)(de)(de)變(bian)化(hua)(hua)(hua)率往往較大。
