Amashanyarazi ya DC

Imashini itanga ingufu za DC ihura na site DC ihanganira ikizamini cya voltage hamwe nigeragezwa ryubu ryumurenge wamashanyarazi, none nigute ushobora guhitamo amashanyarazi ya DC menshi, nigute washyiraho ibipimo, nibisanzwe kandi bidasanzwe?

HV HIPOTGDZG-300 ikurikirana DC itanga amashanyarazi menshi

Imashanyarazi ya DC ikoreshwa cyane mugupima umurima wa DC kwihanganira voltage mumashanyarazi.Gutandukanya ubwoko bwa DC yumuriro mwinshi ni ibikoresho byihariye byo kubyara ingufu za DC mugihe cyo gupima amashanyarazi menshi mumashanyarazi.Muri icyo gihe, irashobora kandi gukora DC yerekana imbaraga za voltage hamwe na testage ya zinc oxyde ya Cinc DC ihanganira ikizamini cya voltage hamwe nikizamini kigezweho.Irakwiriye cyane cyane ikizamini cyumurima ishami rishinzwe kubungabunga amashanyarazi, urugomero rwamashanyarazi nigice cyo gufata amashanyarazi.

Ibigize: Ubwoko bwacitsemo ibice byamashanyarazi ya DC bigizwe ahanini nibice bitanu: agasanduku k'ubugenzuzi, umuvuduko wikubye kabiri, umuvuduko uhwanye nigifuniko, microammeter ya voltage nini, imashanyarazi igabanya ubukana hamwe ninkoni isohoka.

Ibiranga amashanyarazi menshi ya DC:

75% UDC1mA imikorere yibikorwa, byoroshye kubizamini bya zinc oxyde, byukuri 1% gusoma ± 1%.

Kurinda birenze urugero byemera kode ya kode igenamiterere, isobanutse neza, kandi ikosa ni ± 1%.

Umuvuduko wikubye kabiri ukoresha ibintu bishya, byoroshye kandi bikomeye.Ubuso butwikiriwe nibikoresho bidasanzwe byifashisha, bifite amashanyarazi meza kandi birwanya ubushuhe bukomeye.

Kuzunguruka ibirenge bifasha, umwanya munini wa diameter, guhagarara neza.

Igishushanyo mbonera, insinga za voltage zo hejuru zashushanijwe, zoroshye kwipimisha kurubuga.

Ibicuruzwa byujuje ibyangombwa bya tekiniki bya DL / T848.1-2004, kandi yatsinze ikizamini cyubwoko bwikigo cy’amashanyarazi gishinzwe kugenzura no gupima ibikoresho bya minisiteri y’amashanyarazi, kandi gishyira mu bikorwa byimazeyo urwego rw’ibigo.
