電(dian)(dian)阻(zu)(8)是可調電(dian)(dian)阻(zu)。可調電(dian)(dian)阻(zu)(8)的(de)作用是根據被檢測(ce)管線(xian)或電(dian)(dian)氣設備的(de)距離，調節電(dian)(dian)阻(zu)(8)的(de)數值大小，目(mu)的(de)控(kong)制感應(ying)到場效應(ying)管(12)柵極電(dian)(dian)場的(de)強(qiang)弱，從而能夠(gou)有目(mu)的(de)地對不同(tong)檢測(ce)對象進行檢測(ce)。

本發明由(you)于采用了可調的(de)(de)場(chang)效應(ying)管的(de)(de)電(dian)場(chang)感應(ying)原理(li)，且在檢(jian)(jian)測(ce)電(dian)壓放大(da)電(dian)路(lu)中把檢(jian)(jian)測(ce)信號經過二(er)級放大(da)，從而使(shi)微弱的(de)(de)電(dian)場(chang)信號也能(neng)在裝置(zhi)上發光，檢(jian)(jian)測(ce)感應(ying)距(ju)(ju)離比傳統(tong)的(de)(de)檢(jian)(jian)測(ce)裝置(zhi)感應(ying)距(ju)(ju)離長，解(jie)決了傳統(tong)的(de)(de)檢(jian)(jian)測(ce)裝置(zhi)不能(neng)解(jie)決的(de)(de)問題。

當檢測沒有通電(dian)的(de)管(guan)線或電(dian)氣設備(bei)外(wai)殼接(jie)(jie)(jie)地時，雙(shuang)(shuang)極(ji)(ji)雙(shuang)(shuang)擲(zhi)開(kai)關(25)的(de)手(shou)動(dong)(dong)選(xuan)(xuan)擇(ze)端(duan)(duan)(duan)(18)選(xuan)(xuan)擇(ze)棒拔接(jie)(jie)(jie)連接(jie)(jie)(jie)端(duan)(duan)(duan)(20)，雙(shuang)(shuang)極(ji)(ji)雙(shuang)(shuang)擲(zhi)開(kai)關(25)的(de)手(shou)動(dong)(dong)選(xuan)(xuan)擇(ze)端(duan)(duan)(duan)(21)選(xuan)(xuan)擇(ze)棒拔接(jie)(jie)(jie)連接(jie)(jie)(jie)端(duan)(duan)(duan)(23)，雙(shuang)(shuang)極(ji)(ji)雙(shuang)(shuang)擲(zhi)開(kai)關(25)的(de)手(shou)動(dong)(dong)選(xuan)(xuan)擇(ze)端(duan)(duan)(duan)(18)與(yu)雙(shuang)(shuang)極(ji)(ji)雙(shuang)(shuang)擲(zhi)開(kai)關(25)的(de)連接(jie)(jie)(jie)端(duan)(duan)(duan)(20)連接(jie)(jie)(jie)，雙(shuang)(shuang)極(ji)(ji)雙(shuang)(shuang)擲(zhi)開(kai)關(25)的(de)手(shou)動(dong)(dong)選(xuan)(xuan)擇(ze)端(duan)(duan)(duan)(21)與(yu)雙(shuang)(shuang)極(ji)(ji)雙(shuang)(shuang)投開(kai)關(1)的(de)連接(jie)(jie)(jie)端(duan)(duan)(duan)(23)連接(jie)(jie)(jie)，雙(shuang)(shuang)極(ji)(ji)雙(shuang)(shuang)擲(zhi)開(kai)關(25)的(de)手(shou)動(dong)(dong)選(xuan)(xuan)擇(ze)端(duan)(duan)(duan)(21)第二(er)三極(ji)(ji)管(guan)(15)的(de)集電(dian)極(ji)(ji)連接(jie)(jie)(jie)。
