M'makina amakono, -mamita amagetsi agawo limodzi ndiwo zida zazikulu zoyezera kugwiritsa ntchito magetsi kwa ogwiritsa ntchito. Kusankhidwa kwawo kumakhudza mwachindunji kulondola kwa kuyeza, kukhazikika kwa dongosolo, ndi mtengo wamagetsi wa wogwiritsa ntchito. Kusankhidwa kolondola kwa mita imodzi yamagetsi-ya gawo limodzi sikungokhudzana ndi magwiridwe antchito amakampani opanga magetsi, komanso kuteteza ufulu ndi zokonda za ogwiritsa ntchito. Nkhaniyi ifotokoza mwatsatanetsatane mfundo zazikuluzikulu za kusankha mita imodzi yamagetsi-pagawo limodzi kuchokera kuzinthu zaukadaulo, momwe angagwiritsire ntchito, miyezo yotsimikizira ndi zomwe zidzachitike m'tsogolo.
Fotokozani zofunikira zaukadaulo
Kusankhidwa kwa ma mita a magetsi amodzi-agawo kuyenera choyamba kutengera zofunikira zamakina ogwiritsira ntchito. Zofunikira zazikulu ndi izi:
1.Kuvoteledwa kwamagetsi ndi magetsi
Mphamvu yamagetsi ya mita imodzi yamagetsi nthawi zambiri imakhala 220V (kapena 110V, kutengera mulingo wa gridi yachigawo), ndipo mphamvu yake ikuyenera kutsimikiziridwa molingana ndi kukula kwake. Zodziwika bwino zimaphatikizapo 5(60)A, 10(40)A, ndi zina zotero, pomwe mtengo wa m'mabulaketi umayimira pakali pano. Mwachitsanzo, mita yamagetsi ya 5(60)A ndiyoyenera kunyamula zinthu zapakhomo, pomwe mawonekedwe apamwamba (monga 10(100)A) ndi oyenera kuzikidwa m'mafakitale kapena -zida zamagetsi zamphamvu kwambiri.
2.Kulondola Mlingo
Kulondola kwa mita yamagetsi kumakhudzanso chilungamo chamalipiro. Mogwirizana ndi mfundo za dziko la China, kulondola kwa mamita a magetsi a gawo limodzi-ogwiritsidwa ntchito m'nyumba nthawi zambiri amakhala a Gulu 2 (±2% zolakwika). Kugwiritsa ntchito molondola-kwapamwamba kwambiri (monga ma laboratories kapena malo ogulitsira malonda) angafunike Class 0.5S kapena Class 1 mita. Posankha mita, sankhani chitsanzo chomwe chimakwaniritsa zofunikira zolondola malinga ndi zosowa zanu za metering.
3.Frequency and Number of Phases
Mamita amagetsi agawo limodzi-ndi oyenera magidi amagetsi a 50Hz kapena 60Hz (malinga ndi ma gridi a dziko lonse) ndipo amagwiritsidwa ntchito poyeza mphamvu-gawo limodzi la AC. Ngati magawo atatu-ndi mphamvu zamagetsi, -magawo atatu amayenera kusankhidwa.
Kusankhidwa Kutengera Mawonekedwe a Ntchito
Malo osiyanasiyana ogwiritsira ntchito amafunikira ntchito zosiyanasiyana komanso kulimba kwamamita amagetsi, chifukwa chake kusankha koyenera ndikofunikira:
1.Njira Zamagetsi
Ogwiritsa ntchito kunyumba nthawi zambiri amasankha ma metre amagetsi amtundu umodzi-ndi gawo limodzi lokhala ndi ntchito zowerengera. Mamita amakono amakono amathandiziranso kuwerengera mita ndi kulipiriratu, kuwongolera kasamalidwe kabwino. 2. Kulemera kwa malonda ndi mafakitale
Masitolo, maofesi ang'onoang'ono, ndi zochitika zina zingaphatikizepo katundu wambiri wapakatikati (monga ma air conditioners ndi elevator). Ndibwino kuti mugwiritse ntchito mita yokulirapo-yamagetsi osiyanasiyana (monga 5(60)A kapena 10(40)A) ndikuwonetsetsa kuti ili ndi mphamvu yokana kusokonezedwa.
3. Malo apadera
Pamalo otentha kwambiri, achinyezi kapena amphamvu a electromagnetic interferences (monga zipinda zapansi ndi malo ogwirira ntchito kufakitale), m'pofunika kusankha mita yamagetsi yokhala ndi chitetezo chapamwamba (monga IP54 kapena pamwamba) komanso yogwirizana kwambiri ndi electromagnetic (EMC) kuti zitsimikizire kuti zikugwira ntchito kwanthawi yayitali-.
Yang'anani pa ntchito zanzeru ndi kulumikizana
Popanga ma gridi anzeru, ntchito zoonjezera za-mamita amagetsi agawo limodzi zikukhala zofunika kwambiri:
1. Kuthekera kolumikizana kwakutali
Mamita amagetsi omwe amathandizira njira zoyankhulirana monga RS-485, LoRa, ndi NB-IoT imatha kuzindikira kutumiza kwa data kuchokera patali, kuthandizira kuyang'anira nthawi yeniyeni{3}}kuwunika kwanthawi yeniyeni ndi makampani opanga magetsi komanso kufunsa mafunso odzithandizira okha kwa ogwiritsa ntchito.
2. Kulipira kale ndi kuwongolera katundu
Mamita amagetsi olipiriratu amathandizira kugula magetsi kaye kenako ndikuwagwiritsa ntchito, kuchepetsa chiwopsezo cha kubweza ngongole; zina zapamwamba-zokhalanso zomaliza zimakhalanso ndi chitetezo chochulukira chomwe chingachepetse kugwiritsa ntchito magetsi molakwika{1}}
Kusungirako Data ndi Kudula Zochitika
-Mamita amagetsi abwino kwambiri akuyenera kupereka chidziwitso chatsatanetsatane cha momwe magetsi amagwiritsidwira ntchito (monga mphamvu yamagetsi yowumitsidwa tsiku lililonse/mwezi pamwezi) ndi kusungirako zochitika zamavuto kuti athe kuthana ndi mavuto ndikuwunika mphamvu zamagetsi.
Certification ndi Kutsata
Mukasankha mita, onetsetsani kuti yadutsa chiphaso chokakamiza dziko (monga China Compulsory Certification (CCC)) ndipo ikugwirizana ndi mfundo zoyenera (monga mndandanda wa GB/T 17215). Kuphatikiza apo, ngati mitayo idapangidwa kuti itumizidwe kunja kapena kumafakitale ena (monga zachipatala kapena zoyendera njanji), iyenera kukwaniritsa zofunikira zina zotsimikizira (monga CE ndi UL).
Tsogolo Latsopano ndi Zosankha Zosankha
1.Kulondola Kwambiri ndi Kugwiritsa Ntchito Mphamvu Zochepa
Mbadwo watsopano wamamita amagetsi ukupita ku 0.2S-kulondola kwambiri komanso kugwiritsa ntchito magetsi pang'ono-kutsika koyimirira, zomwe zimapangitsa kuti zikhale zoyenera kukumana ndi zofunikira zolimba.
2.Multi-Rate and Energy Efficiency Management
Mamita amagetsi omwe amathandizira nthawi-yo-yogwiritsa ntchito kulipira (chokwera ndi choyimitsa{2}}mitengo yapamwamba) angathandize ogwiritsa ntchito kukweza mtengo wamagetsi ndipo zitha kukhala zodziwika bwino pamsika wanyumba zogona mtsogolo.
3. Modular Design
Mamita amphamvu okhala ndi ma module olankhulirana owonjezera kapena ma sensor interfaces amatha kusinthika kuti agwirizane ndi ukadaulo wamtsogolo.
Chidule cha nkhani: Kusankha mita imodzi yamagetsi pagawo limodzi kumafuna kuganiziridwa mozama pazaukadaulo, mawonekedwe a kagwiritsidwe ntchito, zofunikira mwanzeru, ndi kutsata malamulo. Ogwiritsa ntchito amalangizidwa kuti afotokoze zosowa zawo asanagule ndikuyika patsogolo mitundu yodziwika bwino. Funsani katswiri wa zamagetsi ngati kuli kofunikira kuti muwonetsetse phokoso komanso mtengo-wosankha bwino.
