特性參數

頻率響應

指變(bian)壓器次(ci)級(ji)輸出電壓隨工作頻率變(bian)化的特性(xing)。

變壓器原理

通頻(pin)(pin)帶如果變壓(ya)(ya)(ya)器(qi)在中間頻(pin)(pin)率(lv)(lv)的(de)輸出(chu)電(dian)(dian)壓(ya)(ya)(ya)為U0，正(zheng)泰(tai)變壓(ya)(ya)(ya)器(qi)，當輸出(chu)電(dian)(dian)壓(ya)(ya)(ya)（輸入(ru)電(dian)(dian)壓(ya)(ya)(ya)保持不變）下降到0.707U0時的(de)頻(pin)(pin)率(lv)(lv)范圍(wei)，稱為Sat變壓(ya)(ya)(ya)器(qi)的(de)通頻(pin)(pin)帶B。

初、次級阻抗比

變(bian)壓(ya)器初、次(ci)(ci)級接(jie)入適當的(de)阻(zu)抗(kang)(kang)Ri和Ro，使變(bian)壓(ya)器初、次(ci)(ci)級阻(zu)抗(kang)(kang)匹(pi)配，則(ze)Ri和Ro的(de)比值稱為(wei)初、次(ci)(ci)級阻(zu)抗(kang)(kang)比。在阻(zu)抗(kang)(kang)匹(pi)配的(de)情況(kuang)下(xia)，變(bian)壓(ya)器工(gong)作在醉佳狀態(tai)，傳輸效(xiao)率醉高。

明泰(tai)電(dian)(dian)(dian)氣（蘇州）有限公司(si)是正泰(tai)集團在蘇州地(di)區一家(jia)授權的經銷企業(ye)，連續十年銷量居正泰(tai)營銷網絡名(ming)，公司(si)主要經營“正泰(tai)”牌配電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)(qi)、控制電(dian)(dian)(dian)器(qi)(qi)、終端(duan)電(dian)(dian)(dian)器(qi)(qi)、電(dian)(dian)(dian)源(yuan)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(she)備。

變壓器(qi)的(de)鐵芯需要接地(di)的(de)原因

變(bian)(bian)壓(ya)器(qi)是利用(yong)電(dian)磁(ci)感應(ying)(ying)的(de)(de)原(yuan)理來改變(bian)(bian)交流(liu)電(dian)壓(ya)的(de)(de)裝置，運行上(shang)變(bian)(bian)壓(ya)器(qi)的(de)(de)鐵芯(xin)及其他(ta)附件(jian)都處于繞組周圍的(de)(de)電(dian)場內，如(ru)不接地，鐵芯(xin)及其他(ta)附件(jian)必然感應(ying)(ying)一定的(de)(de)電(dian)壓(ya)。

在(zai)外加電(dian)壓(ya)的(de)(de)作(zuo)用下，當感應電(dian)壓(ya)超過對地(di)放電(dian)電(dian)壓(ya)時(shi)，就會產生放電(dian)現象(xiang)。為了(le)避(bi)免變(bian)壓(ya)器的(de)(de)內部放電(dian)，所以要將鐵芯接地(di)。如果長(chang)期過載運(yun)行，會引起(qi)線圈發(fa)熱，正泰變(bian)壓(ya)器哪家好，使絕緣逐漸老(lao)化(hua)，匣(xia)間短路、相間短路或對地(di)短路及油的(de)(de)分解。

變壓器鐵(tie)芯(xin)絕(jue)緣(yuan)老(lao)化(hua)或夾緊螺栓套管損壞，會使(shi)鐵(tie)芯(xin)產生(sheng)很大的(de)渦流，鐵(tie)芯(xin)長期發(fa)(fa)熱造成絕(jue)緣(yuan)老(lao)化(hua)，變壓器檢修(xiu)吊芯(xin)時，應注意保護線圈或絕(jue)緣(yuan)套管，如果發(fa)(fa)現有擦破損傷，及(ji)時處(chu)理。

變壓器原理

變(bian)壓(ya)(ya)器(qi)(qi)是變(bian)換交流(liu)(liu)電(dian)(dian)壓(ya)(ya)、電(dian)(dian)流(liu)(liu)和阻(zu)抗(kang)(kang)的(de)(de)器(qi)(qi)件，當初(chu)級線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)中(zhong)(zhong)通(tong)有交流(liu)(liu)電(dian)(dian)流(liu)(liu)時(shi)，鐵(tie)芯(xin)（或(huo)(huo)磁(ci)芯(xin)）中(zhong)(zhong)便產生交流(liu)(liu)磁(ci)通(tong)，使(shi)次(ci)級線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)中(zhong)(zhong)感(gan)應(ying)(ying)(ying)出電(dian)(dian)壓(ya)(ya)（或(huo)(huo)電(dian)(dian)流(liu)(liu)）。變(bian)壓(ya)(ya)器(qi)(qi)由鐵(tie)芯(xin)（或(huo)(huo)磁(ci)芯(xin)）和線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)組成，正(zheng)泰(tai)變(bian)壓(ya)(ya)器(qi)(qi)供應(ying)(ying)(ying)，線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)有兩個或(huo)(huo)兩個以(yi)上的(de)(de)繞(rao)(rao)組，其中(zhong)(zhong)接電(dian)(dian)源的(de)(de)繞(rao)(rao)組叫初(chu)級線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)，正(zheng)泰(tai)變(bian)壓(ya)(ya)器(qi)(qi)供應(ying)(ying)(ying)商，其余的(de)(de)繞(rao)(rao)組叫次(ci)級線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)。在(zai)發電(dian)(dian)機中(zhong)(zhong)，不(bu)管是線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)運動(dong)通(tong)過(guo)磁(ci)場(chang)或(huo)(huo)磁(ci)場(chang)運動(dong)通(tong)過(guo)固定線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)，均(jun)(jun)能在(zai)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)中(zhong)(zhong)感(gan)應(ying)(ying)(ying)電(dian)(dian)勢，此(ci)兩種(zhong)情況，磁(ci)通(tong)的(de)(de)值均(jun)(jun)不(bu)變(bian)，但與線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)相交鏈(lian)的(de)(de)磁(ci)通(tong)數量卻有變(bian)動(dong)，這是互感(gan)應(ying)(ying)(ying)的(de)(de)原理。變(bian)壓(ya)(ya)器(qi)(qi)就(jiu)是一種(zhong)利用電(dian)(dian)磁(ci)互感(gan)應(ying)(ying)(ying)，變(bian)換電(dian)(dian)壓(ya)(ya)，電(dian)(dian)流(liu)(liu)和阻(zu)抗(kang)(kang)的(de)(de)器(qi)(qi)件。
