U ka khetha mofuta o nepahetseng joang bakeng sa tester ea voltage?

1. E mamella teko ea motlakase, eo hangata e tsejoang e le "high voltage dielectric test", e bitsoang "withstand voltage test".Molao oa mantlha oa ho khetha mofuta o nepahetseng oa motlakase o mamellang tester ke ho sebelisa motlakase o sebetsang habeli oa ntho e lokelang ho lekoa, ebe o eketsa li-volts tse sekete joalo ka maemo a motlakase a tlhahlobo.Matla a teko a lihlahisoa tse ling a ka ba holimo ho feta 2 × Matla a sebetsang ke + 1000V.Ka mohlala, mefuta ea motlakase e sebetsang ea lihlahisoa tse ling e tloha ho 100V ho ea ho 240V, 'me motlakase oa teko oa lihlahisoa tse joalo o ka ba pakeng tsa 1000V le 4000V kapa ho feta.Ka kakaretso, lihlahisoa tse nang le moralo oa "insulation habeli" li ka sebelisa voltage ea teko e phahameng ho feta 2 × Working voltage + 1000V standard.

Teko ea 2.Thestand voltage e nepahetse haholoanyane moetsong oa sehlahisoa le ho etsa sampole ho feta tlhahiso e hlophisitsoeng, hobane polokeho ea sehlahisoa e ikemiselitse molemong oa moralo le tlhahlobo.Leha ho sebelisoa lisampole tse 'maloa feela ho ahlola moralo oa sehlahisoa, tlhahlobo ea marang-rang nakong ea tlhahiso e lokela ho ba thata haholoanyane.Lihlahisoa tsohle li tlameha ho khona ho fetisa litekanyetso tsa polokeho, 'me ho ka netefatsoa hore ha ho lihlahisoa tse nang le bokooa tse tla phalla ho tsoa mocheng oa tlhahiso.

3.Motlakase o tsoang ho test voltage tester o tlameha ho bolokoa ho tloha ho 100% ho ea ho 120% ea motlakase o boletsoeng.Maqhubu a tlhahiso ea AC standstand voltage tester e tlameha ho bolokoa lipakeng tsa 40Hz le 70Hz, 'me boleng ba eona bo phahameng ha boa lokela ho ba ka tlase ho linako tse 1.3 tsa boleng ba voltage ea "root mean square" (RMS), mme boleng ba eona bo phahameng ha boa lokela ho feta makhetlo a 1.5. ea boleng ba motlakase oa "square mean square" (RMS).

Lihlahisoa tsa 4.Different li na le litlhaloso tse fapaneng tsa tekheniki.Ha e le hantle, tekong ea ho mamella voltage, motlakase o phahameng ho feta o tloaelehileng oa ho sebetsa o sebelisoa ho sehlahisoa bakeng sa tlhahlobo.Voltage e tlameha ho tšoarella nako e itseng.Haeba nako ea ho lutla ha karolo e bolokiloe ka har'a moeli o boletsoeng ka nako e behiloeng, ho ka etsoa qeto ea hore karolo e bolokehile haholo ho sebetsa tlas'a maemo a tloaelehileng.Moralo o motle haholo le khetho ea lisebelisoa tse ntle tsa ho koala li ka sireletsa mosebelisi ho ts'oenyeho ea motlakase ka phoso
