控箱是包含(han)一(yi)個(ge)或多(duo)個(ge)低壓開關設(she)備以及與之(zhi)相關的控制、測量、信號、保(bao)護(hu)、調節等設(she)備，并且由(you)制造廠家負(fu)責用結構部件完整地組裝在一(yi)起的。

接線

1 接(jie)線順序(xu)

待(dai)一切(qie)準備妥當后(hou)(hou)，開始接(jie)線，根據原理圖，首先應(ying)完成主電路(lu)的接(jie)線，然后(hou)(hou)依次接(jie)控制電路(lu)及信號線路(lu)等。

2 放線

放線(xian)(xian)(xian)(xian)時必須根據實際需要(yao)長短(duan)來落料，活(huo)動線(xian)(xian)(xian)(xian)束(shu)應(ying)(ying)考慮最大極限位置(zhi)需用(yong)長度(du)，放線(xian)(xian)(xian)(xian)時盡量利用(yong)短(duan)、零(ling)線(xian)(xian)(xian)(xian)頭，以(yi)免浪費；二次導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)不(bu)(bu)允許有中間接頭、強力(li)拉(la)伸導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)及其(qi)絕緣被破壞的(de)情況，導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)排列應(ying)(ying)盡量減少(shao)彎(wan)曲(qu)和交叉，彎(wan)曲(qu)時對其(qi)彎(wan)曲(qu)半(ban)徑應(ying)(ying)不(bu)(bu)小于3倍(bei)的(de)導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)外徑，并彎(wan)成弧形，導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)交叉時，則(ze)應(ying)(ying)少(shao)數(shu)導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)跨(kua)越多根導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)，細導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)跨(kua)越粗導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)為(wei)原(yuan)則(ze)；布(bu)線(xian)(xian)(xian)(xian)時每根導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)要(yao)拉(la)勒(le)挺直(zhi)，行線(xian)(xian)(xian)(xian)做到(dao)平直(zhi)整齊，式樣美(mei)觀；導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)穿(chuan)越金屬板孔時，必須在金屬板孔上套上合適(shi)的(de)保護物，如橡皮護圈(quan)；導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)束(shu)用(yong)阻(zu)燃纏(chan)(chan)繞(rao)(rao)(rao)(rao)管繞(rao)(rao)(rao)(rao)扎，為(wei)了達到(dao)導(dao)(dao)(dao)(dao)(dao)電時的(de)散熱(re)要(yao)求，纏(chan)(chan)繞(rao)(rao)(rao)(rao)管每繞(rao)(rao)(rao)(rao)一周應(ying)(ying)有3～10mm空隙，同時亦(yi)可(ke)分(fen)(fen)段(duan)纏(chan)(chan)繞(rao)(rao)(rao)(rao)，分(fen)(fen)段(duan)纏(chan)(chan)繞(rao)(rao)(rao)(rao)的(de)間距為(wei)150～180mm，纏(chan)(chan)繞(rao)(rao)(rao)(rao)長度(du)為(wei)100mm，分(fen)(fen)段(duan)纏(chan)(chan)繞(rao)(rao)(rao)(rao)的(de)線(xian)(xian)(xian)(xian)束(shu)，分(fen)(fen)段(duan)亦(yi)應(ying)(ying)整齊，不(bu)(bu)允許參差不(bu)(bu)齊，導(dao)(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)應(ying)(ying)在行線(xian)(xian)(xian)(xian)槽內(nei)行走。

電線(xian)通過接線(xian)頭與接線(xian)及外部元(yuan)件，然(ran)后(hou)(hou)合上斷路(lu)器(qi)，檢查(cha)每一(yi)路(lu)是否工作正常，只有全部的線(xian)路(lu)工作正常后(hou)(hou)才可以(yi)轉入下一(yi)道工序，測試完畢(bi)后(hou)(hou)，接線(xian)槽及接線(xian)端子蓋(gai)板應及時復位蓋(gai)上，電控箱(xiang)內斷路(lu)器(qi)及空氣(qi)開(kai)關(guan)應保(bao)持在(zai)斷開(kai)狀態。
