隔(ge)爆(bao)型電(dian)(dian)纜盤(pan)是(shi)(shi)在(zai)自然環境中用作易(yi)燃、易(yi)爆(bao)物品的(de)(de)(de)安(an)全電(dian)(dian)纜盤(pan)。在(zai)煤礦井下、油氣田或其它存在(zai)易(yi)燃混合物的(de)(de)(de)環境中都很常見。普通電(dian)(dian)纜盤(pan),插銷中間稍有擦傷,即使很小的(de)(de)(de)火焰也會產生危險。隔(ge)爆(bao)電(dian)(dian)纜盤(pan)可避免這類情況的(de)(de)(de)發(fa)生。隔(ge)爆(bao)電(dian)(dian)纜盤(pan)是(shi)(shi)將(jiang)這一自然環境特(te)征與(yu)發(fa)生爆(bao)炸基本(ben)原理相結合而成的(de)(de)(de)技(ji)術專(zhuan)業電(dian)(dian)纜盤(pan)。
1.防爆(bao)型電(dian)纜(lan)(lan)盤(pan)(pan)是(shi)(shi)可避免易(yi)燃易(yi)爆(bao)物(wu)品混(hun)入(ru)物(wu)接觸電(dian)器(qi)元件(jian)極易(yi)引起爆(bao)炸的,一(yi)般使用(yong)(yong)者對電(dian)纜(lan)(lan)盤(pan)(pan)的使用(yong)(yong)比(bi)較生(sheng)疏,纜(lan)(lan)盤(pan)(pan)就是(shi)(shi)配有一(yi)長達100米長的電(dian)纜(lan)(lan)線(xian),由(you)遠(yuan)距離連接開關電(dian)源(yuan)即可處理(li)電(dian)力消耗現場(chang)維護(hu)。普通線(xian)纜(lan)(lan)盤(pan)(pan)上的電(dian)源(yuan)開關和電(dian)源(yuan)插(cha)座(zuo)(zuo)全部(bu)是(shi)(shi)工業生(sheng)產級防水插(cha)座(zuo)(zuo),不能考(kao)慮在特殊易(yi)燃易(yi)爆(bao)物(wu)品條(tiao)件(jian)下使用(yong)(yong),因為電(dian)源(yuan)開關在合分時會(hui)引起電(dian)孤火花放電(dian),假設(she)周圍(wei)存在易(yi)燃性(xing)混(hun)合物(wu)很可能導致引燃甚至發生(sheng)爆(bao)炸,造(zao)成顯著的人員和經濟損失(shi)。
2.一般的開關電源盤式電源插座也只是一般塑膠工業電源插座與防爆電纜盤電源插座不同,拔插時會出現火花放電等現象,與上述情況一樣,假如在某個特定區域也會導致比較嚴重的安全事故,比如不久前江蘇鹽城響水縣化工廠發生爆炸事件,如果選用符合標準的防爆控制箱等機器防(fang)爆電(dian)器設備,按照(zhao)保(bao)安(an)管理單位(wei)的規定(ding)進行整頓(dun),可以防(fang)止(zhi)這次事故的發生。
3.如何完成防爆電纜盤的防(fang)爆(bao)功(gong)能?首先他應用全金(jin)屬焊接而成,將(jiang)電(dian)(dian)(dian)源(yuan)(yuan)開關等(deng)電(dian)(dian)(dian)氣元件內(nei)裝入電(dian)(dian)(dian)纜(lan)(lan)盤,盤體經(jing)防(fang)爆(bao)型解決后(hou),鋼纜(lan)(lan)連接盤處,分組出(chu)線孔(kong)采(cai)用防(fang)爆(bao)式走線孔(kong),電(dian)(dian)(dian)源(yuan)(yuan)插(cha)座選用隔(ge)(ge)爆(bao)型鋁合(he)金(jin)型材(cai)插(cha)座安(an)裝在(zai)電(dian)(dian)(dian)纜(lan)(lan)盤內(nei),隔(ge)(ge)爆(bao)插(cha)頭在(zai)拔插(cha)時不容易引起電(dian)(dian)(dian)火(huo)(huo)花或火(huo)(huo)花放電(dian)(dian)(dian),從而達到防(fang)爆(bao)型的實際效果。
4.防爆(bao)纜盤生(sheng)產(chan)工藝不同于普通(tong)電(dian)(dian)纜盤。抗爆(bao)電(dian)(dian)纜盤適(shi)用(yong)于2區和(he)3區,這兩個(ge)區域(yu)有時會產(chan)生(sheng)可燃(ran)(ran)氣體混合物及(ji)它們的易燃(ran)(ran)煙塵。不易連(lian)續(xu)發生(sheng)易燃(ran)(ran)危(wei)險自然環境。電(dian)(dian)線(xian)盤根長度(du)(du)一般在100米(mi)以內,長度(du)(du)可根據用(yong)戶要(yao)求(qiu)定做,防爆(bao)型電(dian)(dian)纜盤里軸旋轉方便,移(yi)動(dong)時能(neng)帶動(dong)護欄(lan),底端安(an)裝滾軸,可隨(sui)意拖放。內置中(zhong)、小型漏電(dian)(dian)保(bao)護裝置,合理維護人體觸電(dian)(dian)造(zao)成的傷害(hai)。
