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)。

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。
