電氣控制柜二次回路布線工藝

發布日期:2022-04-26 點擊率:87


 ?。?、所有二次回路連接導線中間不應有接頭,連接頭只能位于器件的接線端子或接線端子排上。
 ?。贰⒚總€電器元件的接點最多允許接2 根線。每個端子的接線點一般不宜接二根導線,特殊情況時如果必須接兩根導線,則連接必須可靠。
 ?。?、二次線應遠離飛弧元件,并不得防礙電器的操作 。
 ?。埂㈦娏鞅砼c分流器的連線之間不得經過端子,其線長不得超過3 米。
 ?。保?、電流回路宜經過試驗端子接至測量儀表。
 ?。保?、多股導線端部應加冷壓端頭接線。弱電回路中截面面積小于1m㎡的單股導線應采用錫焊或其它合適的方式接線。



 ?。保?、二次線不得從母線相間穿過,如下圖:



 ?。保?、回拉式彈簧端子的聯接:
   1)硬導線的剝線長度: 10 mm左右
   2)軟導線應套上線鼻子壓緊后后再插到端子,注意銅線芯不要露出線鼻子且要壓實。
