Muri sisitemu zamashanyarazi zigezweho, metero imwe - icyiciro cyamashanyarazi nibikoresho byingenzi byo gupima abakoresha amashanyarazi. Guhitamo kwabo bigira ingaruka ku buryo butaziguye bwo gupimwa, guhagarara kwa sisitemu, no gukoresha amashanyarazi. Guhitamo neza metero imwe - icyiciro cyamashanyarazi ntabwo kijyanye gusa nubushobozi bwimikorere yamasosiyete yingufu, ahubwo no kurengera uburenganzira ninyungu zabakoresha ba nyuma. Iyi ngingo izasobanura kuri gahunda ingingo zingenzi za metero imwe ya - icyiciro cya metero yumuriro w'amashanyarazi uhereye mubice bya tekiniki, ibintu bisabwa, ibipimo byemeza hamwe niterambere ryigihe kizaza.
Sobanura ibipimo bya tekiniki ibisabwa
Guhitamo metero imwe - icyiciro cyamashanyarazi kigomba kubanza gushingira kubisabwa tekiniki yibisabwa. Ibyingenzi byingenzi birimo:
1.Byerekanwe na voltage nubu
Umuvuduko wapimwe wa metero imwe - icyiciro cyamashanyarazi ubusanzwe ni 220V (cyangwa 110V, bitewe nurwego rwamashanyarazi mukarere), kandi amashanyarazi yagenwe agomba kugenwa akurikije ingano yumutwaro. Ibisobanuro bisanzwe birimo 5 (60) A, 10 (40) A, nibindi, aho agaciro mumutwe kerekana icyerekezo kinini. Kurugero, metero 5 (60) Imetero yamashanyarazi ikwiranye nimizigo isanzwe yo murugo, mugihe ibisobanuro bihanitse (nka 10 (100) A) bikwiranye ninganda cyangwa hejuru - ibikoresho byamashanyarazi.
Urwego rwukuri
Uburebure bwa metero y'amashanyarazi bugira ingaruka ku buryo butaziguye. Ukurikije ibipimo by’igihugu cy’Ubushinwa, urwego rwukuri rwa metero imwe - icyiciro cyamashanyarazi kugirango ukoreshwe muri rusange ni Icyiciro cya 2 (error 2% ikosa). Hejuru - Porogaramu zisobanutse neza (nka laboratoire cyangwa gutura mu bucuruzi) zishobora gusaba Icyiciro 0.5S cyangwa metero 1. Mugihe uhitamo metero, hitamo icyitegererezo cyujuje ibyangombwa bisabwa ukurikije ibyo ukeneye.
3.Ubunini n'umubare w'ibyiciro
Imashanyarazi imwe - icyiciro cya mashanyarazi ikwiranye na 50Hz cyangwa 60Hz ya gride (bitewe nuburinganire bwigihugu) kandi ikoreshwa gusa mugupima ingufu imwe - icyiciro cya AC. Niba imbaraga zitatu - zirimo, metero eshatu - zigomba gutoranywa.
Guhitamo Bishingiye ku Gusaba
Ibidukikije bitandukanye bikoresha bisaba imirimo itandukanye kandi biramba kuri metero z'amashanyarazi, guhitamo rero birakenewe:
1.Amashanyarazi atuye
Abakoresha murugo mubisanzwe bahitamo icyuma gisanzwe cya elegitoronike - icyiciro cyamashanyarazi hamwe nibikorwa byibanze byo gupima. Imashini zigezweho zigezweho nazo zishyigikira metero ya kure gusoma no kwishyura mbere, kunoza imikorere . 2. Imizigo yubucuruzi ninganda
Amaduka, ibiro bito, nibindi bintu bishobora kuba bikubiyemo imizigo iremereye rimwe na rimwe (nka konderasi na lift). Birasabwa gukoresha metero nini - intera yumuriro w'amashanyarazi (nka 5 (60) A cyangwa 10 (40) A) kandi ukemeza ko ifite ubushobozi bwo kurwanya kwivanga.
3. Ibidukikije bidasanzwe
Mu bushyuhe bwo hejuru, ubuhehere cyangwa imbaraga zikomeye za electromagnetic zibangamira ibidukikije (nko munsi yo hasi no mumahugurwa y'uruganda), birakenewe guhitamo metero y'amashanyarazi ifite urwego rwo hejuru rwo kurinda (nka IP54 cyangwa hejuru) hamwe na electromagnetic ihuza imbaraga (EMC) kugirango ikore igihe kirekire -.
Wibande kumikorere yubwenge no gutumanaho
Hamwe niterambere rya gride yubwenge, imirimo yinyongera ya metero imwe - icyiciro cyamashanyarazi igenda iba ingenzi:
1. Ubushobozi bwo gutumanaho kure
Imetero y'amashanyarazi ishyigikira protocole y'itumanaho nka RS - 485, LoRa, na NB - IoT irashobora kubona amakuru yoherejwe kure, byorohereza gukurikirana - igihe gikurikiranwa n’amasosiyete y’amashanyarazi hamwe n’ibibazo byifashishwa n’abakoresha.
2. Kwishyura mbere no kugenzura imizigo
Imashanyarazi yishyuwe mbere ishyigikira kugura amashanyarazi mbere hanyuma kuyikoresha, kugabanya ibyago byibirarane; bimwe murwego rwo hejuru - moderi zanyuma nazo zifite ibikorwa byo gukingira birenze urugero bishobora guhagarika kure gukoresha ingufu zidasanzwe . 3.
Kubika Data no Kwinjira
Ibipimo by'amashanyarazi biri hejuru - bigomba gutanga amakuru arambuye yo gukoresha amashanyarazi (nko gukoresha amashanyarazi ya buri munsi / buri kwezi) hamwe no kubika ibyabaye kugirango byoroherezwe gukemura no gusesengura ingufu.
Icyemezo no kubahiriza
Mugihe uhisemo metero, menya neza ko watsinze ibyemezo byigihugu byemewe (nkubushinwa bwemewe (CCC)) kandi bwujuje ubuziranenge (nka seriveri ya GB / T 17215). Byongeye kandi, niba metero igenewe koherezwa hanze cyangwa inganda zihariye (nk'ubuvuzi cyangwa gari ya moshi), igomba kuba yujuje ibyangombwa bisabwa (nka CE na UL).
Ibyerekezo bizaza hamwe nibyifuzo byo guhitamo
1.Ibisobanuro Byukuri hamwe no gukoresha ingufu nke
Igisekuru gishya cya metero z'amashanyarazi kiratera imbere kigana kuri 0.2S - urwego rwo hejuru rwukuri hamwe na ultra - gukoresha ingufu nke zidasanzwe, bigatuma bikwiranye na ssenariyo hamwe nibisabwa bikomeye.
2.Multi - Igipimo cyo gucunga neza ingufu
Imetero y'amashanyarazi ishyigikira igihe - ya - gukoresha fagitire (impinga na off - igiciro cyo hejuru) irashobora gufasha abakoresha gukoresha ibiciro by'amashanyarazi kandi birashobora kuba ikintu nyamukuru mumasoko yo guturamo mugihe kizaza.
3. Igishushanyo mbonera
Imetero yingufu hamwe niyaguka ryitumanaho ryagutse cyangwa sensor interineti irashobora guhuza neza nogutezimbere tekinoroji.
Incamake: Guhitamo metero imwe - icyiciro cya metero yingufu bisaba gutekereza cyane kubisobanuro bya tekiniki, ibintu byakoreshejwe, ibisabwa byubwenge, no kubahiriza amabwiriza. Abakoresha barasabwa gusobanura ibyo bakeneye mbere yo kugura no gushyira imbere ibirango bizwi. Baza numu injeniyeri wumwuga wabigize umwuga nibiba ngombwa kugirango umenye amajwi nigiciro - guhitamo neza.
