Monga chipangizo chachikulu choyezera mphamvu zamagetsi m'makina amagetsi, magwiridwe antchito amamita amagetsi amakhudza kulondola, kudalirika, komanso chilungamo cha kuyeza kwa mphamvu. Chifukwa chakukula mwachangu kwa ma gridi anzeru ndi matekinoloje atsopano amagetsi, mita yamagetsi sayenera kungokwaniritsa ntchito zoyambira metering komanso kukhala ndi luntha lapamwamba, luso lolankhulana, komanso kusinthasintha kwa chilengedwe. Nkhaniyi ifufuza zizindikiro zazikulu zogwirira ntchito ndi zofunikira zaumisiri zamamita amagetsi kuchokera pakuwona kulondola, kukhazikika, kudalirika, nzeru, ndi kusinthasintha kwa chilengedwe.
Kulondola kwa Metering: Chizindikiro Chogwira Ntchito Pamagetsi Amagetsi
Kulondola kwa mita yamagetsi ndichinthu chofunikira kwambiri pakugwira ntchito, kukhudza mwachindunji kukhazikitsidwa kwa bilu yamagetsi ogwiritsa ntchito komanso kudalirika kwa data yochokera kumakampani opanga magetsi. Miyezo yapadziko lonse lapansi (monga IEC 62053) ndi malamulo adziko nthawi zambiri amakhazikitsa miyezo yolondola ya mita yamagetsi. Miyezo yolondola yodziwika bwino imaphatikizapo 0.2s, 0.5s, 1.0, ndi 2.0, ndi manambala otsika omwe amaimira kulondola kwambiri. -Mamita olondola kwambiri a magetsi amagwiritsa ntchito-stability current transformer (CTs) ndi ma voltage transformers (PTs), kuphatikiziridwa ndi luso lapamwamba la analogi{{10}to{11}}digital conversion (ADC), pofuna kutsimikizira kuyeza kolondola pansi pa katundu wosiyanasiyana (monga mphamvu yocheperako komanso kuvulaza kwambiri-). Komanso, ma smart metre akuyenera kuphatikizirapo-kuthekera kokwanira kuti musunge{15}kulondola kwa mita.
Kukhazikika ndi Kudalirika Kwanthawi yayitali-Kwanthawi yayitali
Kukhazikika kwa mita kumatanthawuza kuthekera kwake kosunga kulondola kwa mita pa nthawi yayitali yogwira ntchito. Zinthu zomwe zimakhudza kukhazikika zimaphatikizira kukalamba kwazinthu, kusinthasintha kwa kutentha, ndi kusokonezedwa ndi ma elekitiroma. -Mamita apamwamba kwambiri amagwiritsa ntchito-zigawo zamagetsi zodalirika komanso zoyezetsa ukalamba kuti zitsimikizire kuti mita ikugwira ntchito kwa zaka zoposa 10.
Kudalirika kumatanthauza kuthekera kwa mita kugwira ntchito m'malo ovuta, monga kutentha kwambiri ndi kutsika, chinyezi, ndi kugwedezeka. Mamita a Industrial-nthawi zambiri amagwirizana ndi miyezo ya electromagnetic compatibility (EMC) monga IEC 61000, yomwe imateteza chitetezo ku zosokoneza kwakanthawi monga kugunda kwa mphezi ndi mafunde, kuwonetsetsa kuti kusonkhanitsa deta sikukhudzidwa ndi chilengedwe.
Luntha ndi Kuyankhulana
Mamita amakono anzeru samangokhala ndi ntchito zama metering zamakina achikhalidwe kapena zamagetsi komanso amaphatikiza ma microprocessors, kukumbukira, ndi ma module olumikizirana kuti athandizire kuwerenga kwamamita akutali, kasamalidwe ka katundu, kuzindikira molakwika, ndi ntchito zina. Ma Smart mita amagwiritsa ntchito njira zolankhulirana izi:
•Kulankhulana opanda zingwe (monga LoRa, NB-IoT, ndi Wi-Fi) potumiza m'madera;
•Kulankhulana ndi mawaya (monga RS-485 ndi Power Line Carrier (PLC)) kwa kasamalidwe kapakati.
Kuphatikiza apo, mita yanzeru nthawi zambiri imathandizira njira zoyankhulirana zapadziko lonse lapansi monga DLMS/COSEM kuti zitsimikizire kuti zimagwirizana ndi machitidwe owongolera mphamvu kuchokera kwa ogulitsa osiyanasiyana.
Kusinthasintha Kwachilengedwe ndi Chitetezo
Mamita amagetsi atha kuyikidwa panja, m'zipinda zapansi, kapena m'malo opangira mafakitale, chifukwa chake ayenera kukhala ndi kusinthasintha kwachilengedwe. Zitsanzo ndi izi:
•Kusiyanasiyana kwa kutentha kwa ntchito (monga -40 digirii kufika ku +70 digiri);
•Kukana madzi ndi fumbi (IP65 kapena apamwamba);
•Mapangidwe osagwirizana ndi corrosion{0}} kuti agwiritsidwe ntchito m'malo a chinyezi chambiri kapena malo opopera mchere. Pankhani yachitetezo, mita yamagetsi iyenera kutsatira miyezo yachitetezo chamagetsi (monga IEC 62052) kuti apewe zoopsa monga kugwedezeka kwamagetsi, kuchulukirachulukira, ndi ma frequency afupi. Ayeneranso kuwonetsetsa zachinsinsi za ogwiritsa ntchito ndikuletsa kulowa kapena kusokoneza mosaloledwa.
Mapeto
Kugwira ntchito kwa mita yamagetsi kumakhudza mwachindunji magwiridwe antchito amagetsi amagetsi komanso kuchuluka kwa kasamalidwe kamphamvu kamphamvu. Kulondola kwambiri, kukhazikika kwakukulu, luntha, komanso kusinthika kwamphamvu kwachilengedwe ndizofunika kwambiri pamamita amakono amagetsi. Ndi chitukuko cha intaneti ya Mphamvu, mamita amagetsi amtsogolo adzaphatikizanso matekinoloje monga kusanthula kwa AI ndi kusunga deta ya blockchain kuti apititse patsogolo kulondola kwa metering ndi kuyendetsa bwino, kupereka chithandizo chodalirika chaukadaulo pakusintha kwamphamvu padziko lonse lapansi.
