配電箱:

利用率(lv)高,占(zhan)地面積小,具有環(huan)保效果的特點。它(ta)是指揮供(gong)電線(xian)路中(zhong)各部(bu)件合理分配(pei)電能的控制(zhi)中(zhong)心(xin)。它(ta)是一個可(ke)靠(kao)的控制(zhi)環(huan)節,可(ke)以接受上端電源,正確饋送負(fu)荷電能,也(ye)是獲得用戶對供(gong)電質(zhi)量滿意度的關鍵。提高動力配(pei)電箱的運行(xing)可(ke)靠(kao)性是創建高質(zhi)量項目(mu)的目(mu)標。

配(pei)電(dian)箱的(de)使用:電(dian)能分配(pei)合(he)理,便(bian)于電(dian)路的(de)開閉操(cao)作。安全防護等級高,可直觀顯示電(dian)路的(de)導通狀態。

常(chang)用(yong)的(de)配電箱(xiang)有木制(zhi)和(he)金屬制(zhi)兩種,因為金屬配電箱(xiang)的(de)防護等(deng)級較高,所(suo)以金屬的(de)使用(yong)較多(duo)。

根據結構特點用途(tu)分類(lei):

(1)固定(ding)面(mian)板(ban)開關(guan)(guan)(guan)(guan)柜(ju)(ju)(ju),通(tong)常(chang)稱為(wei)開關(guan)(guan)(guan)(guan)板(ban)或(huo)配(pei)(pei)電(dian)(dian)(dian)屏幕。它是一(yi)種開關(guan)(guan)(guan)(guan)柜(ju)(ju)(ju),正面(mian)有(you)(you)保護(hu)(hu)作(zuo)用(yong)(yong),背面(mian)和(he)側(ce)面(mian)仍能(neng)(neng)(neng)接(jie)觸(chu)帶電(dian)(dian)(dian)部(bu)分(fen),保護(hu)(hu)水平(ping)低(di),只能(neng)(neng)(neng)用(yong)(yong)于(yu)供(gong)(gong)電(dian)(dian)(dian)連續性(xing)和(he)可(ke)靠性(xing)要求較低(di)的(de)(de)工礦(kuang)企業,作(zuo)為(wei)變電(dian)(dian)(dian)室集(ji)中供(gong)(gong)電(dian)(dian)(dian)。(2)保護(hu)(hu)(即(ji)封(feng)閉(bi)(bi)(bi)式(shi)(shi))開關(guan)(guan)(guan)(guan)柜(ju)(ju)(ju),是指除安裝(zhuang)(zhuang)表面(mian)外(wai),所有(you)(you)其他(ta)側(ce)面(mian)都(dou)關(guan)(guan)(guan)(guan)閉(bi)(bi)(bi)的(de)(de)低(di)壓開關(guan)(guan)(guan)(guan)柜(ju)(ju)(ju)。該機(ji)柜(ju)(ju)(ju)的(de)(de)開關(guan)(guan)(guan)(guan)。保護(hu)(hu)、監測、控(kong)制(zhi)(zhi)(zhi)等(deng)電(dian)(dian)(dian)氣元(yuan)件均安裝(zhuang)(zhuang)在鋼或(huo)絕(jue)(jue)緣(yuan)材料(liao)制(zhi)(zhi)(zhi)成的(de)(de)封(feng)閉(bi)(bi)(bi)外(wai)殼內(nei),安裝(zhuang)(zhuang)在可(ke)靠的(de)(de)墻(qiang)壁(bi)或(huo)隔離(li)(li)墻(qiang)上。機(ji)柜(ju)(ju)(ju)內(nei)的(de)(de)每個電(dian)(dian)(dian)路都(dou)可(ke)以用(yong)(yong)接(jie)地金屬板(ban)或(huo)絕(jue)(jue)緣(yuan)板(ban)隔離(li)(li),而無需隔離(li)(li)措施。通(tong)常(chang),門(men)和(he)主開關(guan)(guan)(guan)(guan)操作(zuo)都(dou)有(you)(you)機(ji)械(xie)聯鎖。此(ci)外(wai),還有(you)(you)防(fang)(fang)護(hu)(hu)臺式(shi)(shi)開關(guan)(guan)(guan)(guan)柜(ju)(ju)(ju)(即(ji)控(kong)制(zhi)(zhi)(zhi)臺),面(mian)板(ban)上安裝(zhuang)(zhuang)有(you)(you)控(kong)制(zhi)(zhi)(zhi)、測量、信號等(deng)電(dian)(dian)(dian)器。防(fang)(fang)護(hu)(hu)開關(guan)(guan)(guan)(guan)柜(ju)(ju)(ju)主要用(yong)(yong)于(yu)工藝現(xian)場(chang)。(3)功能(neng)(neng)(neng)單(dan)元(yuan)之間的(de)(de)可(ke)靠性(xing)。通(tong)常(chang),門(men)和(he)主開關(guan)(guan)(guan)(guan)操作(zuo)都(dou)有(you)(you)機(ji)械(xie)聯鎖。此(ci)外(wai),還有(you)(you)一(yi)種防(fang)(fang)護(hu)(hu)臺式(shi)(shi)開關(guan)(guan)(guan)(guan)柜(ju)(ju)(ju)(即(ji)控(kong)制(zhi)(zhi)(zhi)臺式(shi)(shi)開關(guan)(guan)(guan)(guan)柜(ju)(ju)(ju))。適用(yong)(yong)于(yu)供(gong)(gong)電(dian)(dian)(dian)可(ke)靠性(xing)高的(de)(de)工礦(kuang)企業。高層(ceng)建筑,作(zuo)為(wei)集(ji)中控(kong)制(zhi)(zhi)(zhi)的(de)(de)配(pei)(pei)電(dian)(dian)(dian)中心。(4)電(dian)(dian)(dian)源。照明和(he)配(pei)(pei)電(dian)(dian)(dian)控(kong)制(zhi)(zhi)(zhi)箱。它們大多(duo)是封(feng)閉(bi)(bi)(bi)的(de)(de)垂直安裝(zhuang)(zhuang)。由于(yu)使用(yong)(yong)場(chang)合不(bu)(bu)同(tong),殼體(ti)保護(hu)(hu)等(deng)級也不(bu)(bu)同(tong)。主要用(yong)(yong)作(zuo)工礦(kuang)企業生產現(xian)場(chang)的(de)(de)配(pei)(pei)電(dian)(dian)(dian)裝(zhuang)(zhuang)置。

結構

配電箱結構分(fen)為兩種。

1.焊接(jie)結構(gou):簡單地將(jiang)鈑金件切割.彎曲.開孔后(hou)焊接(jie)。

2.組裝結構(gou):單(dan)獨(du)加工(gong)鈑金件。每(mei)個部(bu)件加工(gong)后(hou),用螺釘和(he)三通加固鎖(suo)緊。外觀美觀,操作簡單(dan),可節省大(da)量運輸(shu)成(cheng)本(ben)。

配(pei)電(dian)(dian)箱(xiang)、配(pei)電(dian)(dian)柜、配(pei)電(dian)(dian)盤(pan)、配(pei)電(dian)(dian)屏、電(dian)(dian)氣柜等,是集中安裝開關、儀器等設備的(de)成(cheng)套(tao)設備,防爆配(pei)電(dian)(dian)箱(xiang)與普通(tong)配(pei)電(dian)(dian)箱(xiang)的(de)區別在于:

在形狀上(shang),普(pu)通配電箱(xiang)是鐵制的,而防(fang)爆配電箱(xiang)是鑄造或(huo)焊接而成,強度較高。

在(zai)結構上,普通配電箱(xiang)內(nei)部件可排列在(zai)一起,布線(xian)方便,防爆配電箱(xiang)內(nei)部分為多(duo)個(ge)單元,每個(ge)開關。電氣元件應(ying)隔離。

在密(mi)封(feng)方(fang)面,普通配電(dian)箱(xiang)對密(mi)封(feng)要求不是很嚴(yan)格(ge)。防爆配電(dian)箱(xiang)蓋與箱(xiang)體密(mi)封(feng)良(liang)好。經嚴(yan)格(ge)檢查合格(ge)后,由專門機構頒發并出廠銷售。

在應(ying)用(yong)中(zhong),普通配電(dian)箱一般用(yong)于民(min)用(yong)場所,無(wu)防(fang)爆(bao)要求。防(fang)爆(bao)配電(dian)箱主(zhu)要用(yong)于危險(xian)可燃氣體和爆(bao)炸性場所。

普通配電(dian)箱(xiang)價格(ge)便宜(yi)。防爆配電(dian)箱(xiang)價格(ge)昂(ang)貴,一般是(shi)普通配電(dian)箱(xiang)價格(ge)的幾倍。

配電(dian)(dian)箱一(yi)般用(yong)于(yu)(yu)家庭,配電(dian)(dian)柜多(duo)用(yong)于(yu)(yu)集中(zhong)供電(dian)(dian),如工(gong)業用(yong)電(dian)(dian)和建筑用(yong)電(dian)(dian)。配電(dian)(dian)箱和配電(dian)(dian)柜均為(wei)成(cheng)套設備,配電(dian)(dian)箱為(wei)低壓(ya)(ya)成(cheng)套設備,配電(dian)(dian)柜高(gao)壓(ya)(ya)低壓(ya)(ya)。

防(fang)爆配電箱(xiang):防(fang)爆配電箱(xiang):

防爆配電箱是一種具有防爆性能的配電箱。主要包括防爆照明配電箱、防(fang)爆(bao)(bao)(bao)動力配電(dian)(dian)箱、防(fang)爆(bao)(bao)(bao)防(fang)腐配電(dian)(dian)箱等。BXM(D)防(fang)爆(bao)(bao)(bao)配電(dian)(dian)箱適用于石化(hua)(hua)裝置(zhi)、石油平臺、化(hua)(hua)工、制藥、煤(mei)炭、冶煉、船舶制造(zao)、軍工、紡(fang)織等易燃(ran)易爆(bao)(bao)(bao)場所.2區(qu)(qu)爆(bao)(bao)(bao)炸性(xing)氣體環(huan)境。20.21區(qu)(qu).22區(qu)(qu)可燃(ran)粉塵環(huan)境。

隨著(zhu)石油(you)、化工、軍(jun)工、工程、工廠、礦山、礦業等行業的(de)(de)快(kuai)速發展,防(fang)爆(bao)配電(dian)(dian)箱(xiang)在(zai)生產(chan)、儲存、救(jiu)援中(zhong)的(de)(de)應(ying)用(yong)越來越廣泛(fan),品種也越來越多。如何防(fang)止(zhi)爆(bao)炸(zha)(zha)性(xing)配電(dian)(dian)箱(xiang)事故爆(bao)炸(zha)(zha)已(yi)成為爆(bao)炸(zha)(zha)性(xing)氣(qi)體(ti)危險(xian)場所(suo)的(de)(de)一(yi)個非(fei)常重要(yao)的(de)(de)課(ke)題。由(you)于防(fang)爆(bao)配電(dian)(dian)箱(xiang)在(zai)工作中(zhong)不可(ke)避(bi)免(mian)地會(hui)產(chan)生電(dian)(dian)火花(hua),一(yi)旦遇到生產(chan)或(huo)救(jiu)援現場的(de)(de)爆(bao)炸(zha)(zha)性(xing)氣(qi)體(ti)混合物,就會(hui)導致爆(bao)炸(zha)(zha)事故,直接危及國家財產(chan)和公民的(de)(de)生命安全。因此,作為使(shi)用(yong)最廣泛(fan)的(de)(de)照明(ming)設備,其防(fang)爆(bao)技術(shu)問題已(yi)經(jing)引起了人們的(de)(de)廣泛(fan)關注和高(gao)度關注。
