真空度測試儀特點(dian)：

基于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)的(de)(de)(de)(de)(de)采(cai)樣(yang)(yang)技(ji)術均采(cai)用基于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)的(de)(de)(de)(de)(de)采(cai)樣(yang)(yang)技(ji)術。該(gai)公(gong)(gong)司(si)專(zhuan)家在磁放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)研究(jiu)中發現，在外(wai)激勵(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源、真(zhen)(zhen)空(kong)滅(mie)弧(hu)(hu)(hu)(hu)室的(de)(de)(de)(de)(de)幾(ji)(ji)何(he)尺寸、所(suo)用材料一定(ding)時，真(zhen)(zhen)空(kong)滅(mie)弧(hu)(hu)(hu)(hu)室里(li)的(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)度(du)與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離的(de)(de)(de)(de)(de) 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)量(liang)(liang)(liang)(liang)有(you)非常準確的(de)(de)(de)(de)(de)對應關系，而與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)(de)峰值僅有(you)概(gai)率(lv)上的(de)(de)(de)(de)(de)相關性(xing)(xing)(xing)。因此，我公(gong)(gong)司(si)首刨了基于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)的(de)(de)(de)(de)(de)采(cai)樣(yang)(yang)技(ji)術，顯著提高(gao)(gao)了真(zhen)(zhen)空(kong)滅(mie)弧(hu)(hu)(hu)(hu)室的(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)度(du)計(ji)量(liang)(liang)(liang)(liang)的(de)(de)(de)(de)(de)準確性(xing)(xing)(xing)。 漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)(de)處理(li) 對處于(yu)(yu)分斷狀態(tai)的(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)滅(mie)弧(hu)(hu)(hu)(hu)室兩(liang)端加高(gao)(gao)壓時，會有(you)數(shu)值不(bu)(bu)等的(de)(de)(de)(de)(de)幾(ji)(ji)個微安(an)的(de)(de)(de)(de)(de)漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，此漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)即使是同型號的(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)滅(mie)弧(hu)(hu)(hu)(hu)室也有(you)較大(da)的(de)(de)(de)(de)(de)個體差異。尤(you)其是對于(yu)(yu)裝(zhuang)在整(zheng)機上的(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)滅(mie)弧(hu)(hu)(hu)(hu)室，由(you)(you)于(yu)(yu)其周邊的(de)(de)(de)(de)(de)絕緣支撐(cheng)件也有(you)漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，這此漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)總和有(you)更大(da)的(de)(de)(de)(de)(de)不(bu)(bu)穩定(ding)性(xing)(xing)(xing)和不(bu)(bu)可預測性(xing)(xing)(xing)，并且在數(shu)值上與10E- 4Pa 數(shu)量(liang)(liang)(liang)(liang)級的(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)滅(mie)弧(hu)(hu)(hu)(hu)室的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)相當。我們采(cai)用兩(liang)次起動高(gao)(gao)壓的(de)(de)(de)(de)(de)方法(fa)，扣(kou)除了漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，保證了無論是裝(zhuang)于(yu)(yu)整(zheng)機上還是待裝(zhuang)的(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)滅(mie)弧(hu)(hu)(hu)(hu)室的(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)計(ji)量(liang)(liang)(liang)(liang)精度(du)。 內置國(guo)內外(wai)幾(ji)(ji)乎所(suo)有(you)真(zhen)(zhen)空(kong)滅(mie)弧(hu)(hu)(hu)(hu)室的(de)(de)(de)(de)(de)測量(liang)(liang)(liang)(liang)曲線(xian) 真(zhen)(zhen)空(kong)滅(mie)弧(hu)(hu)(hu)(hu)室由(you)(you)于(yu)(yu)其幾(ji)(ji)何(he)尺寸、材料的(de)(de)(de)(de)(de)不(bu)(bu)同，當內部真(zhen)(zhen)空(kong)度(du)和外(wai)加激勵(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源一定(ding)時，其放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)量(liang)(liang)(liang)(liang)是不(bu)(bu)同的(de)(de)(de)(de)(de)，并且有(you)相當的(de)(de)(de)(de)(de)差異。

因此，該系列產(chan)品(pin)內置國內外(wai)幾乎所有真空(kong)滅弧(hu)室的(de)(de)(de)測量曲線。這是國內外(wai)同類產(chan)品(pin)中無(wu)有的(de)(de)(de)。 完善(shan)的(de)(de)(de) 輸入保(bao)護電路 當真空(kong)滅弧(hu)室的(de)(de)(de)真空(kong)度(du)(du)非常低時，測量時真空(kong)滅弧(hu)室會(hui)被高(gao)壓(ya)擊穿，瞬間的(de)(de)(de)高(gao)壓(ya)直(zhi)接加至信(xin)(xin)號(hao)輸入端(duan)的(de)(de)(de) 采樣(yang)電路上，使其承受十分強的(de)(de)(de)電沖擊。真空(kong)度(du)(du)測試儀(yi)的(de)(de)(de)信(xin)(xin)號(hao)輸入端(duan)的(de)(de)(de)采樣(yang)電路增加了(le)完備的(de)(de)(de) 保(bao)護電路，即使儀(yi)器由于輸入端(duan)的(de)(de)(de)高(gao)壓(ya)沖擊而發(fa)生暫時工作不(bu)正(zheng)常時（重新(xin)開(kai)機(ji)即可(ke)），也(ye)不(bu)會(hui)造成電路部分的(de)(de)(de)損壞。
