一、驗電器是檢驗什么的儀器

驗電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是一種檢測(ce)物體(ti)是否帶(dai)電(dian)(dian)(dian)(dian)(dian)以及粗略估計(ji)帶(dai)電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)大(da)小(xiao)的(de)(de)(de)儀器(qi)(qi)，當被檢驗物體(ti)接(jie)觸驗電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)頂端的(de)(de)(de)導體(ti)時，自身所帶(dai)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)荷(he)會傳到玻璃鐘罩內的(de)(de)(de)箔片上(shang)。由于同(tong)種電(dian)(dian)(dian)(dian)(dian)荷(he)相(xiang)互排斥，箔片將(jiang)自動分開，張(zhang)(zhang)成一定角度(du)。根(gen)據兩箔片張(zhang)(zhang)成角度(du)的(de)(de)(de)大(da)小(xiao)可(ke)估計(ji)物體(ti)帶(dai)電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)的(de)(de)(de)大(da)小(xiao)。其實這是箔片所受電(dian)(dian)(dian)(dian)(dian)場力包括箔片上(shang)同(tong)名的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)荷(he)的(de)(de)(de)斥力和(he)器(qi)(qi)皿(min)內壁異名電(dian)(dian)(dian)(dian)(dian)荷(he)的(de)(de)(de)吸引力。如果將(jiang)玻璃瓶改(gai)為(wei)使用金屬盒以便屏蔽靜(jing)電(dian)(dian)(dian)(dian)(dian)、金屬棒和(he)器(qi)(qi)皿(min)引出導線以便測(ce)量(liang)(liang)兩點間(jian)電(dian)(dian)(dian)(dian)(dian)勢差(cha)、增加(jia)刻度(du)以便將(jiang)結果量(liang)(liang)化，那么驗電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)可(ke)以改(gai)造為(wei)更精確(que)的(de)(de)(de)靜(jing)電(dian)(dian)(dian)(dian)(dian)計(ji)。

二、驗電器是基本安全用具嗎

驗電器既可(ke)(ke)以作(zuo)(zuo)為基(ji)本安全(quan)用具使(shi)用，也可(ke)(ke)以作(zuo)(zuo)為輔助安全(quan)用具使(shi)用。

驗(yan)電(dian)(dian)(dian)(dian)器(qi)在電(dian)(dian)(dian)(dian)氣安(an)全(quan)檢測中具有非常重(zhong)要的(de)作用(yong)，它可(ke)(ke)以(yi)幫助(zhu)工人識別設備是否帶(dai)電(dian)(dian)(dian)(dian)或者帶(dai)有電(dian)(dian)(dian)(dian)壓，為電(dian)(dian)(dian)(dian)氣安(an)全(quan)提供(gong)了保障。同時，在工業領(ling)域中，驗(yan)電(dian)(dian)(dian)(dian)器(qi)也是一(yi)種重(zhong)要的(de)安(an)全(quan)用(yong)具，它可(ke)(ke)以(yi)作為基本安(an)全(quan)用(yong)具使(shi)用(yong)，幫助(zhu)工人避免(mian)因電(dian)(dian)(dian)(dian)氣問(wen)題引(yin)發的(de)事故。在一(yi)些(xie)危(wei)險(xian)系數(shu)較高的(de)情況下，也可(ke)(ke)以(yi)作為輔助(zhu)安(an)全(quan)用(yong)具使(shi)用(yong)。

三、驗電器是感應起電還是接觸起電

驗電(dian)器是通過接觸起電(dian)的方式工作(zuo)的。

驗電(dian)(dian)(dian)(dian)器(qi)是(shi)一種(zhong)(zhong)用(yong)于(yu)檢(jian)測物體(ti)是(shi)否(fou)帶電(dian)(dian)(dian)(dian)以及粗略(lve)估(gu)計帶電(dian)(dian)(dian)(dian)量大小的(de)(de)儀器(qi)。其工作(zuo)原(yuan)(yuan)理(li)基(ji)于(yu)同(tong)(tong)種(zhong)(zhong)電(dian)(dian)(dian)(dian)荷(he)(he)(he)相互(hu)排斥的(de)(de)原(yuan)(yuan)理(li)。當被檢(jian)驗物體(ti)接觸(chu)(chu)驗電(dian)(dian)(dian)(dian)器(qi)頂(ding)端的(de)(de)導體(ti)時，自身所(suo)帶的(de)(de)電(dian)(dian)(dian)(dian)荷(he)(he)(he)會(hui)傳到(dao)玻(bo)璃(li)鐘(zhong)罩內的(de)(de)箔片上(shang)(shang)。由于(yu)同(tong)(tong)種(zhong)(zhong)電(dian)(dian)(dian)(dian)荷(he)(he)(he)相互(hu)排斥，箔片將自動分開(kai)，張成一定角度。根據兩箔片張成角度的(de)(de)大小，可(ke)以估(gu)計物體(ti)帶電(dian)(dian)(dian)(dian)量的(de)(de)大小。這種(zhong)(zhong)通過(guo)物體(ti)與驗電(dian)(dian)(dian)(dian)器(qi)的(de)(de)金屬球(qiu)接觸(chu)(chu)，導致電(dian)(dian)(dian)(dian)荷(he)(he)(he)傳到(dao)驗電(dian)(dian)(dian)(dian)器(qi)上(shang)(shang)的(de)(de)鋁(lv)箔上(shang)(shang)，進而根據同(tong)(tong)種(zhong)(zhong)電(dian)(dian)(dian)(dian)荷(he)(he)(he)相斥的(de)(de)原(yuan)(yuan)理(li)來判斷(duan)物體(ti)是(shi)否(fou)帶電(dian)(dian)(dian)(dian)的(de)(de)過(guo)程(cheng)，屬于(yu)接觸(chu)(chu)起(qi)電(dian)(dian)(dian)(dian)。

雖然驗(yan)電(dian)(dian)器(qi)的(de)(de)工(gong)作(zuo)原理涉及到接(jie)(jie)觸起(qi)電(dian)(dian)，但也可以(yi)(yi)通(tong)(tong)過改(gai)造(zao)，如使(shi)用金屬盒以(yi)(yi)便屏蔽(bi)靜(jing)電(dian)(dian)、金屬棒(bang)和器(qi)皿引出導線以(yi)(yi)便測(ce)(ce)量兩點間電(dian)(dian)勢差、增加刻(ke)度以(yi)(yi)便將結果(guo)量化，從而(er)使(shi)其成為更精確(que)的(de)(de)靜(jing)電(dian)(dian)計。這(zhe)種(zhong)改(gai)造(zao)并不改(gai)變(bian)驗(yan)電(dian)(dian)器(qi)基本的(de)(de)工(gong)作(zuo)原理，即通(tong)(tong)過接(jie)(jie)觸帶電(dian)(dian)物體(ti)來檢測(ce)(ce)和測(ce)(ce)量電(dian)(dian)荷。
