Nigute ushobora gukoresha ibizamini bya voltage neza?

Nubwo ubu ari kwizerwa kwihanganira ibizamini bya voltage, mugikorwa, birashobora gutera ingaruka zimwe kubakoresha bitewe nibibazo bimwe na bimwe nk'ingaruka z'abakora ubwabo cyangwa isi yo hanze.Niyo mpamvu, ibigo byombi bizobereye mu gukora ibizamini bya voltage bihanganye n’ibigo bireba bifashisha ibizamini bya voltage bigomba kugerageza ibishoboka byose kugira ngo hatabaho ingaruka nk'izi, None se ni gute wagabanya ibyago nk'ibi bishobora kubaho?

Muri rusange, abantu benshi bo murwego rwohejuru barwanya ibizamini bya voltage byakozwe hamwe na sisitemu yubwenge irwanya amashanyarazi menshi.Sisitemu nayo yitwa GFI ifite ubwenge mugihe gito.Irashobora gutahura ukurikije imikoreshereze yubu.Niba ikibazo cyo guhitanwa n amashanyarazi no kumeneka bibaye, uwujuje ibyangombwa byihanganira igeragezwa rya voltage azahita ahagarika ingufu za voltage nyinshi muri milisegonda imwe, Kugirango umutekano wabakoresha.Kubwibyo, mugihe kimwe cyibikorwa, uwujuje ibyangombwa ashobora kwihanganira ibipimo bya voltage, mugihe cyose uwabikoze adakoze amakosa menshi, ntibishobora kwibasira amashanyarazi amashanyarazi nibindi byago.

Mu rwego rwo kurinda abaguzi n’abakoresha, abakora ibizamini byingutu bakeneye kurangiza ubwoko butandukanye bwibizamini byumutekano iyo barangije umusaruro wibikoresho, kugirango barebe ko ibicuruzwa byubahiriza inganda zerekana imiterere yibikorwa, imikorere nibikorwa byihariye. .Harimo voltage kwihanganira ikizamini, ikizamini cyokwirinda, nibindi.Kugeza ubu, uruganda rwujuje ibyangombwa, umusaruro waryo, ibizamini nibindi bikorwa bigomba gukorwa hubahirijwe ibipimo ngenderwaho bya ISO, kandi ibicuruzwa byanyuma bigomba no kugera ku bipimo ngenderwaho bya ISO ku isi, ni ukuvuga kuva mu bice kugeza ku bicuruzwa byarangiye. Tugomba kugera kuri ISO yubuziranenge bwubuziranenge, gusa murubu buryo dushobora kurushaho kurandura burundu ingaruka zishobora kubaho.Birumvikana ko gukoresha ibikoresho bifitanye isano n’ibigo bifitanye isano, ariko kandi bigategura buri gihe imikorere y amahugurwa y abakozi, ibishya bigomba kugenzurwa nabakozi bakuze babimenyereye gukora, kugirango birinde burundu ingaruka ziterwa namakosa yibikorwa.

1. Ni izihe nyungu za AC zihanganira ikizamini cya voltage

Mubisanzwe, AC kwihanganira ibipimo bya voltage biroroshye kubona inkunga yumuryango wumutekano kuruta DC kwihanganira ibizamini bya voltage.Impamvu nyamukuru nuko ibyinshi mubintu byageragejwe bizakora munsi yumuriro wa AC, kandi AC ihangane na voltage itanga inyungu zo guhinduranya polarisi ebyiri kugirango ushire igitutu kuri insulasiyo, ikaba yegereye igitutu ibicuruzwa bizahura nabyo mugukoresha nyabyo.Kuberako ikizamini cya AC kitazishyuza ubushobozi bwumutwaro, isomwa ryubu rirahoraho kuva intangiriro ya voltage ikoreshwa kugeza ikizamini kirangiye.Kubwibyo, kubera ko ntakibazo gihari gisabwa kugirango ukurikirane ibisomwa biriho, nta mpamvu yo kongera voltage intambwe ku yindi.Ibi bivuze ko keretse niba ibicuruzwa biri munsi yikizamini byumva voltage ikoreshwa gitunguranye, uyikoresha arashobora guhita akoresha voltage yuzuye hanyuma agasoma ikigezweho adategereje.Kuberako amashanyarazi ya AC atazishyuza umutwaro, nta mpamvu yo gusohora ibikoresho byapimwe nyuma yikizamini.

2. Ni izihe nenge za test ya AC voltage?

Iyo ubushobozi bwa capacitive bwageragejwe, igiteranyo cyose kigizwe na reaction ya reaction na leakage.Iyo imiyoboro irwanya imbaraga nini cyane kuruta imyanda yamenetse, birashobora kugorana kumenya ibicuruzwa bifite umuyaga mwinshi.Mugihe ugerageza umutwaro munini wa capacitive, igiteranyo gisabwa ni kinini cyane kuruta imyuka ubwayo.Kuberako umukoresha ahura nibindi bigezweho, ibi birashobora kuba akaga gakomeye.

3. Ni izihe nyungu za DC zihanganira ikizamini cya voltage?

Iyo DUT yishyuwe byuzuye, gusa ibyukuri bitemba bitemba.Ibi bifasha DC kwihanganira igikoresho cyo gupima voltage kugirango yerekane neza ibintu byukuri biva mubicuruzwa.Kuberako amashanyarazi yumuriro ari mugufi, ingufu zisabwa na DC zihanganira igeragezwa rya voltage mubusanzwe ni nto cyane ugereranije na AC ihanganira ibizamini bya voltage ikoreshwa mugupima ibicuruzwa bimwe.

4. Ni izihe nenge za DC zihanganira ibipimo bya voltage?

Kuberako DC voltage yihanganira ikizamini yishyuza ikintu kiri mukigeragezo (DLT), kugirango ikureho ingaruka ziterwa numuriro wumuriro wumukoresha ukora ikintu kiri munsi yikizamini (DLT) nyuma yikizamini cya voltage, ikizamini (DLT) kigomba kuba gusezererwa nyuma yikizamini.Ikizamini cya DC kizishyuza ubushobozi.Niba DUT ikoresha AC imbaraga, uburyo bwa DC ntabwo bwigana ibintu bifatika.
