三相變壓器繞組的端頭標(biāo)志與極性(同名端)變壓器首尾端標(biāo)志

發(fā)布日期:2022-10-11 點(diǎn)擊率:681

繞組名稱 單相變壓器 三相變壓器 中點(diǎn)


  首端 尾端 首端 尾端

  高壓繞組A X A、B、CX、Y、ZN

  低壓繞組a X a、b、c x、y、zn

  中壓繞組Am Xm Am、Bm、CmXm、Ym、ZmNm


  當(dāng)高壓繞組某一端頭電位高于另一端時(shí),低壓繞組在該瞬時(shí)也有一個(gè)端頭電位高于另一端,則這兩個(gè)具有高電位的端頭就是同極性端(或同名端)。一般在同極性端的端頭標(biāo)上"·" 標(biāo)記;當(dāng)然另外兩個(gè)低電位的端頭也是同極性端,但無(wú)須再標(biāo)記同極性端與繞組的繞向有關(guān)。
