Amamitha kagesi-esigaba esisodwa angamadivayisi abalulekile okulinganisa ukusetshenziswa kwamandla kubasebenzisi bezindawo zokuhlala nabancane bezentengiselwano. Ukusebenza nokuthembeka kwabo kuhlobene ngqo nokulunga kwezindawo zokuhwebelana ngogesi. Ukuqinisekisa ukunemba kwesilinganiso, ukuphepha, nokushintshashintsha, amazinga aqinile okusebenzisa asesungulwe emhlabeni jikelele. Izwe lami linamathela ngokuyinhloko ochungechungeni olujwayelekile lwe-GB/T 17215, ngokubhekiselwa kuzichasiselo ezifanele ze-International Electrotechnical Commission (IEC).
Isistimu Ejwayelekile Yasekhaya
amazinga emitha kagesi esigaba esisodwa-esigaba esisodwa sezwe lami agxile ku-GB/T 17215.211-2021, "Izisetshenziswa Zokulinganisa Zikagesi - Ukuthembeka - Ingxenye 211: Izidingo Zokwethenjelwa Zamamitha Kagesi,"{1/2}2015 {1}2} ne-GB5{2}2}2 "I-Stationary AC Active Energy Meters (Ikilasi 1 nelesi-2)." Owokuqala ucacisa izidingo zamamitha wamandla mayelana nokuguquguquka kwemvelo, amandla emishini, nokuzinza kokusebenza kwesikhathi eside; eyakamuva ichaza amapharamitha wobuchwepheshe afana nebanga lokunemba, isiqalo samanje, kanye nebanga lesici samandla se-Class 1 kanye ne-2 yamamitha wamandla asebenzayo. Isibonelo, umkhawulo wephutha wamamitha we-Class 1 ngu-±1%, futhi kumamitha we-Class 2, ungu-±2%. Ukunemba kufanele kugcinwe ngaphakathi kwebanga elingu-0.1Ib (10% wesisekelo samanje) ukuya ku-Imax (ubuningi bamanje). Ngaphezu kwalokho, i-GB/T 15284-2022 yengeza imisebenzi nezindlela zokuhlola zamamitha kagesi wamazinga amaningi, edinga ukusekelwa kohlelo lwesikhathi nokugcinwa kwedatha.
Ukuvumelanisa Okujwayelekile Kwamazwe Ngamazwe
Emazweni ngamazwe, uchungechunge lwamazinga e-IEC 62053 (afana ne-IEC 62053-}21:2020) isebenza njengesiqondiso esivamile{9}}sesigaba esisodwa somklamo wamamitha kagesi futhi ihambisana kakhulu nezindinganiso zezwe lami. Lawa mazinga achaza ukuhambelana kuka-electromagnetic (EMC), ukubekezelela izinga lokushisa nokuswakama (isb, ububanzi bokusebenza obusuka ku- -25℃kuya ku-+60℃), kanye nezidingo zedizayini ezimelene nokuphazamisa. Ngaphezu kwalokho, amazinga esifunda afana ne-EN 50470 ye-EU kanye ne-ANSI C12.10 yaseNyakatho Melika ahlanganisa izinhlinzeko ezihlukene mayelana nokuguquguquka kokuguquguquka kagesi kanye nezindawo zokuxhumana (isb, i-infrared ne-RS-485). Ukuqaliswa Okubalulekile Nokuthrendayo
Uhlelo oluqinile lwamazinga luqinisekisa ukuba semthethweni nokuthuthuka kobuchwepheshe bemitha kagesi. Ngokuthuthukiswa kwamagridi ahlakaniphile, amazinga akamuva ahlanganisa kancane kancane izidingo zokuxhumana kwe-HPLC, ukulinganisa okukude, nokuqapha umthwalo oguqukayo. Abakhiqizi kudingeka baphumelele ukuhlolwa kokuhlolwa kohlobo (njengokuhlolwa kwesitifiketi se-CNAS se-China Electric Power Research Institute) ukuze baqinisekise ukuthobelana namazinga kuwo wonke umjikelezo wabo wokuphila womkhiqizo. Ngokuzayo, amazinga azophinde agxile{3}ekubekeni imitha kwekhabhoni ephansi kanye nokuphepha kwenethiwekhi, okuqhubeza ukuvela kwamamitha kagesi ukuya ekunembeni okuphezulu kanye nobuchwepheshe obukhaliphile.
Kafushane, amazinga okuqalisa{0}esigaba esisodwa samamitha kagesi awumphumela webhalansi phakathi kokucaciswa kobuchwepheshe kanye nesidingo semakethe. Ukuthuthukisa kwabo okuqhubekayo kunikeza ukwesekwa okuthembekile kobuchwepheshe bokuphathwa kwamandla omhlaba.
