Imashini imwe - icyiciro cyamashanyarazi nibikoresho byibanze byo gupima ingufu zikoreshwa kubakoresha amazu mato mato. Imikorere yabo no kwizerwa bifitanye isano itaziguye nubucuruzi bwimashanyarazi. Kugirango ibipimo bifatika, umutekano, no guhinduranya, hashyizweho amahame akomeye yo gushyira mu bikorwa ku isi. igihugu cyanjye gikurikiza cyane cyane amahame ngenderwaho ya GB / T 17215 yigihugu, hifashishijwe komisiyo mpuzamahanga ishinzwe amashanyarazi (IEC).
Sisitemu yo mu Gihugu
igihugu cyanjye kimwe - icyiciro cya metero yumuriro w'amashanyarazi gishingiye kuri GB / T 17215.211 - 2021, "Ibikoresho byo gupima amashanyarazi - Kwishingikiriza - Igice cya 211: Ibisabwa byiringirwa kubipimo by'amashanyarazi," na GB / T 17215.321 - 2021, "Sitasiyo ya AC 1 Iyambere irerekana ibisabwa kuri metero zingufu zijyanye no guhuza ibidukikije, imbaraga za mashini, hamwe nigihe kirekire cyo gukora; icya nyuma gisobanura ibipimo bya tekiniki nkurwego rwukuri, gutangira ibyagezweho, nimbaraga zingero zicyiciro cya 1 na 2 metero zikoresha ingufu. Kurugero, ikosa ntarengwa kuri metero 1 ni ± 1%, naho kuri metero 2, ni ± 2%. Ukuri kugomba kubikwa muburyo bwa 0.1Ib (10% byibanze shingiro) kugeza Imax (ikigezweho). Byongeye kandi, GB / T 15284-2022 yuzuza imikorere nuburyo bwo gupima metero nyinshi zamashanyarazi, bisaba inkunga mugihe cyo gutangiza gahunda no kubika amakuru.
Guhuza Ibipimo Mpuzamahanga
Ku rwego mpuzamahanga, urutonde rwa IEC 62053 (nka IEC 62053 - 21: 2020) rukora nk'umurongo ngenderwaho rusange wo gushushanya metero imwe y'amashanyarazi - kandi uhuza cyane n'ibipimo by'igihugu cyanjye. Ibipimo ngenderwaho birambuye kubijyanye na electromagnetic ihuza (EMC), kwihanganira ubushyuhe nubushuhe (urugero, urugero rwa dogere -25 kugeza kuri +60), hamwe nibisabwa byo kurwanya tamping. Byongeye kandi, ibipimo by'akarere nka EN 50470 y’ubumwe bw’ibihugu by’Uburayi na ANSI C12.10 yo muri Amerika y'Amajyaruguru bikubiyemo ingingo zinyuranye zerekeye ihindagurika ry’imihindagurikire y’imihindagurikire y’imihindagurikire y’itumanaho (urugero, infragre na RS-485). Gushyira mu bikorwa Akamaro n'ibigenda
Sisitemu ihamye yerekana uburyo bwemewe niterambere ryikoranabuhanga mu gupima amashanyarazi. Hamwe niterambere rya gride yubwenge, ibipimo bigezweho bigenda byinjizamo buhoro buhoro ibisabwa kugirango itumanaho rya HPLC, kalibrasi ya kure, hamwe no kugenzura imitwaro ifite imbaraga. Ababikora basabwa gutsinda ibizamini byo gusuzuma ubwoko (nk'ikizamini cya CNAS cyo mu Bushinwa gishinzwe ubushakashatsi ku mashanyarazi) kugira ngo bubahirize ibipimo mu buzima bwabo bwose. Mu bihe biri imbere, ibipimo bizakomeza kwibanda ku gipimo gito cya - no gupima umutekano wa neti, bigatuma ihindagurika rya metero z'amashanyarazi rigana ku buhanga buhanitse kandi buhanga.
Muri make, ibipimo byo gushyira mubikorwa metero imwe - icyiciro cyamashanyarazi nigisubizo cyuburinganire hagati yubuhanga bukenewe nibisabwa ku isoko. Gukomeza gutezimbere bitanga inkunga yizewe yo gucunga ingufu zisi.
