SL-2006型便攜式充氣電纜氫氣查漏儀

【功能及用途】
該儀器是(shi)用(yong)來準確檢測充氣(qi)(qi)(qi)(qi)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)漏(lou)氣(qi)(qi)(qi)(qi)點的設備(bei)。當前市內電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)干線無(wu)一(yi)例外都采用(yong)壓縮空氣(qi)(qi)(qi)(qi)充氣(qi)(qi)(qi)(qi)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)，光纖(xian)通信使用(yong)充氣(qi)(qi)(qi)(qi)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)也已(yi)成為(wei)定(ding)勢。因(yin)為(wei)對(dui)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)實施(shi)充氣(qi)(qi)(qi)(qi)維(wei)護是(shi)行之(zhi)有效(xiao)的保(bao)(bao)護措施(shi)，能(neng)(neng)防止潮氣(qi)(qi)(qi)(qi)和(he)水份的侵入(ru)，從而(er)保(bao)(bao)證電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的電(dian)(dian)(dian)(dian)氣(qi)(qi)(qi)(qi)特(te)性，并為(wei)監測電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)漏(lou)氣(qi)(qi)(qi)(qi)故障和(he)判(pan)斷漏(lou)氣(qi)(qi)(qi)(qi)的區段提供了(le)先決條(tiao)件，但(dan)對(dui)充氣(qi)(qi)(qi)(qi)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)漏(lou)氣(qi)(qi)(qi)(qi)點作定(ding)點定(ding)位，則長期不能(neng)(neng)解(jie)決，因(yin)而(er)，克服(fu)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)漏(lou)氣(qi)(qi)(qi)(qi)，提高電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)保(bao)(bao)護率是(shi)一(yi)項十分艱巨的工作。
該儀器(qi)廣(guang)泛應用于(yu)電(dian)信、路燈管理所、通(tong)訊等使(shi)用充(chong)氣(qi)電(dian)纜(lan)的單位和部門。 

SL-2006型便攜式充氣電纜氫氣查漏儀

【特點】
*靈敏度高：0.0001%氫氣(qi)(qi)含量就(jiu)能檢查出來，而且不受氟里(li)昂(ang)、甲烷及大(da)多數(shu)其他氣(qi)(qi)體的影響。
*精(jing)度(du)高；典(dian)型漏(lou)點(dian)定位精(jing)度(du)在實際漏(lou)點(dian)0.3米半徑范圍之內(nei)，實際應用常常在數厘米范圍之內(nei)，這是因為氫分子量zui小、zui輕、穿(chuan)透力強、粘滯性小、擴散性小的緣故。
*操(cao)(cao)作簡便：只需(xu)5分(fen)鐘便能掌握(wo)系(xi)統的操(cao)(cao)作。
*安全性好；5%氫氣(qi)(qi)和(he)95%氮(dan)氣(qi)(qi)的示蹤氣(qi)(qi)體(ti)無(wu)毒、無(wu)味(wei)、無(wu)腐蝕性、不可燃。這種示蹤氣(qi)(qi)體(ti)是(shi)工業焊接工作(zuo)中(zhong)用(yong)(yong)來保(bao)護不銹鋼避免(mian)氧化的常(chang)用(yong)(yong)氣(qi)(qi)體(ti)，因此非常(chang)容易獲(huo)得。
*可靠性強：實(shi)踐(jian)證(zheng)明(ming)，其查漏率為(wei)100%。
*工作效率(lv)高(gao)。 

【主要技術指標】
▲檢漏(lou)范圍：0-5000ppm；
▲報(bao)警(jing)設定(ding)值：5-1000ppm范(fan)圍內任意設定(ding)，可(ke)調 
【檢測原(yuan)理及方法】
將氫氣(qi)(5%)和氮(dan)氣(qi)(95%)的混(hun)合氣(qi)體以一定的壓力注入電纜中，在管線鋪設(she)方向上搜尋氣(qi)體，近而*定位漏點(dian)位置。
