Buku Lotsogolera Kusankha kwa WiFi Smart Energy Meter CT: Momwe Mungasankhire Cholumikizira Chamakono Choyenera

Chiyambi: Chifukwa Chake Kusankha CT N'kofunika mu WiFi Smart Energy Metering

MukatumizaMita yamagetsi yanzeru ya WiFi, ogwiritsa ntchito ambiri amayang'ana kwambiri pa kulumikizana, mapulogalamu, kapena kuphatikizana kwa mtambo. Komabe, chinthu chimodzi chofunikira nthawi zambiri chimaonedwa ngati chonyozeka:chosinthira chamagetsi (cholumikizira cha CT).

Kusankha CT rating yolakwika kungakhudze mwachindunji kulondola kwa muyeso—makamaka ngati katundu ndi wochepa. Ichi ndichifukwa chake mafunso monga:"Kodi ndisankhe ma CT a 80A, 120A, kapena 200A?" or "Kodi CT yayikulu idzakhalabe yolondola pa mafunde ang'onoang'ono?"nthawi zambiri zimachitika panthawi yokonzekera polojekiti.

Bukuli likufotokoza momwe ma CT clamp amagwirira ntchito, chifukwa chake kukula koyenera kuli kofunika, komanso momwe mungasankhire mtundu woyenera wa CT kuti muwone mphamvu zenizeni—pogwiritsa ntchito zitsanzo zothandiza kutengera ma WiFi smart meter monga PC321.

Momwe Ma CT Clamps Amayezera Mphamvu mu WiFi Energy Meters

Chotsekera cha CT chimayesa mphamvu yamagetsi pozindikira mphamvu ya maginito yopangidwa ndi kondakitala. Kenako chizindikiro choyezedwacho chimasinthidwa kukhala mphamvu yachiwiri yochepetsedwa yomwe mita yamagetsi imatha kuikonza.

Chotsekera chilichonse cha CT chimapangidwa ndiyovotera panopa, monga 80A, 120A, kapena 200A. Chiyerekezo ichi chimafotokoza mtundu wa momwe CT imagwirira ntchito molondola motsimikizika pansi pa mikhalidwe yoyesera yokhazikika.

Chofunika kwambiri, kulondola kwa CT sikugwirizana pamlingo wonse—zimadalira momwe mphamvu yeniyeni yogwirira ntchito ilili pafupi ndi mphamvu ya CT.

Kumvetsetsa Ma Ratings Olondola a CT ndi Ma Operating Ranges

Ma clamp ambiri a CT omwe amagwiritsidwa ntchito mu ma smart energy meter amatsatira miyezo yolondola ya Class 1.0.

Kulondola kumatanthauzidwa mkati mwa mtundu winawake wamagetsi ogwirira ntchito, nthawi zambiri kuyambira 5% mpaka 100% yamagetsi ovoteledwa, monga momwe zafotokozedwera mu miyezo yapadziko lonse lapansi ya ma transformer a zida (mwachitsanzo,IEC 61869).

Mu gawo ili, CT ikhoza kukwaniritsa±Kulondola kwa muyeso wa 1% pansi pa mikhalidwe yoyesera yokhazikika.

Mwachitsanzo:

A 200A CTimasunga kulondola kwa Kalasi 1.0 kuyambira pafupifupi10A mpaka 200A
A 40A CTimasunga kulondola komweko kuyambira pafupifupi2A mpaka 40A

Izi zikufotokoza chifukwa chake kukula kwa CT kumakhudza mwachindunji magwiridwe antchito a muyeso wamagetsi otsika.

Kodi Chimachitika N'chiyani Ngati CT Yaikulu Ikuyesa Mphepo Yaing'ono?

Funso lofala ndi lakuti kodi200A CT imatha kuyeza molondola katundu wa 40AYankho lalifupi ndi ili:Inde, zidzagwira ntchito—koma sizingakhale bwino kwambiri.

Chifukwa chiyani kulondola kungachepe pamlingo wotsika wamagetsi

Ngati CT ndi yayikulu kwambiri:

Chizindikiro chachiwiri chimakhala chochepa kwambiri pamagetsi otsika
Kutsimikiza kwa muyeso kumachepa
Phokoso ndi cholakwika cha gawo zimaonekera kwambiri
Mphamvu zochepa komanso mphamvu zochepa zimakhudzidwa kwambiri

Ngakhale kuti CT ingakwaniritsebe zofunikira za Gulu 1.0 malinga ndi momwe zinthu zilili mu labotale,kukhazikitsa zenizeni—ndi phokoso lamagetsi, katundu wosakhala wolunjika, ndi mafunde osinthasintha—akhoza kukhala ndi kulondola kochepa kwa katundu.

Ichi ndichifukwa chake ma CT omwe ali ndi kukula kofanana ndi mphamvu yeniyeni yogwirira ntchito nthawi zambiri amaperekakulondola bwino kwabwino, ngakhale ma CT onse awiri ali ndi kalasi yofanana ya kulondola kwa dzina.

Njira Yabwino Kwambiri: Momwe Mungasankhire CT Rating Yoyenera

Gawo 1: Dziwani kuchuluka kwa magetsi komwe kukuyembekezeka

Gwiritsani ntchito chimodzi mwa izi:

Chiyeso cha kuswa kwa dera
Zida zodziwika bwino
Deta yakale yokhudza katundu (ngati ilipo)

Gawo 2: Gwiritsani ntchito lamulo lothandiza pa kukula kwa kukula

Malangizo aukadaulo ovomerezedwa kwambiri ndi awa:

Mphamvu yamagetsi ya CT ≈ 1.2–1.5 × mphamvu yayikulu yogwirira ntchito yomwe ikuyembekezeka

Njira iyi imapereka:

Malire okwanira kuti katundu akhale wokwera kwambiri
Kusasinthika bwino panthawi yogwira ntchito bwino
Khalidwe labwino la kuyeza mphamvu yamagetsi otsika

Kusankha Kwachizolowezi kwa CT pa Ntchito Zokhala ndi Mabizinesi

Kutengera ndi zomwe zidachitikadi pakukhazikitsa ntchito ndiMamita anzeru a WiFimonga PC321:

Malo okhala

80A CT: Yoyenera zipinda zazing'ono kapena mabwalo opanda mphamvu zambiri
120A CT: Amagwiritsidwa ntchito kwambiri m'nyumba za ku North America, zomwe zimapereka mgwirizano wabwino pakati pa kuphimba ndi kulondola kochepa kwa katundu

Kukhazikitsa kwa malonda

200A CT: Yodziwika bwino pa malo odyetsera ang'onoang'ono amalonda ndi mafakitale ang'onoang'ono
CT 300A kapena kupitirira apo: Imagwiritsidwa ntchito pamene kukula kwa chingwe kapena kukulitsa mtsogolo kumafuna malo owonjezera a mutu

Mwachidule, ogwiritsa ntchito ambiri amakonda kugwiritsa ntchito njira ziwiri za CT—imodzi yogwiritsira ntchito nyumba ndi ina yogwiritsira ntchito malonda—kuti zinthu zomwe zili m'nyumba zikhale zosavuta komanso zosavuta kuziyika.

Kukula kwa Chingwe ndi Kukula kwa Zenera la CT: Choletsa Chothandiza

Kusankha CT sikungokhudza kuwerengera kwamakono kokha.Chingwe cha m'mimba mwake chiyenera kulowa mkati mwa zenera la CT.

Mwachitsanzo:

Ma CT ang'onoang'ono angapereke kulondola kwabwino kwa mphamvu yochepa
Ma CT akuluakulu amapereka kugwirizana kwakukulu kwa chingwe komanso kuyika kosavuta

Choletsa ichi cha makina nthawi zambiri chimakhudza kusankha kwa CT komanso kuganizira za magetsi.

Owon PC321 monga Chitsanzo Chothandiza cha Kusankha kwa CT

TheMita yamagetsi yanzeru ya PC321 WiFiImathandizira mitundu yosiyanasiyana ya ma CT clamps osinthika. Kusinthasintha kumeneku kumalola opanga makina kusintha njira yosankha ma CT kutengera:

Tsekani mbiri
Malo okhazikitsa
Zofunikira zolondola
Miyeso ya chingwe

Kuphatikiza apo, kulinganiza mulingo wa dongosolo pakati pa mita ndi ma CT clamp kumathandiza kutsimikizira magwiridwe antchito odalirika pamitundu yosiyanasiyana ya CT.

Kodi Kukonza Kungabwezeretse Ma CT Aakulu Kwambiri?

Kukonza bwino kungathandize kuti dongosolo lonse likhale lolondola, komasizingathe kuchotsa kwathunthu zofooka zakuthupi za ma CT akuluakulupa mafunde otsika kwambiri.

Ngakhale kuwerengera mbali ya mita ndi kubwezera kwa digito kumathandiza:

Zoletsa za chizindikiro cha phokoso zikugwirabe ntchito
Cholakwika cha gawo pamagetsi otsika kwambiri chikadali chinthu chofunikira

Chifukwa chake,Kukula koyenera kwa CT kumakhalabe njira yothandiza kwambiri yopezera miyeso yokhazikika komanso yolondola.

Mfundo Zofunika Kwambiri Zokhudza Kusankha CT

Ma CT akuluakulu amatha kuyeza mafunde ang'onoang'ono, koma kulondola kwa katundu wochepa kungachepe
Kulondola kwa CT kumatsimikizika kokha mkati mwa peresenti yodziwika ya mphamvu yovotera
Kusankha CT yoyandikana ndi malo enieni ogwirira ntchito kumawongolera kulondola kwa dziko lenileni
Kuyenerera kwa makina ndi momwe amaikidwira n'kofunika monga momwe magetsi amaonera.
Zosankha zosinthika za CT, monga zomwe zimathandizidwa ndi PC321, zimapangitsa kuti makina azigwira ntchito bwino.

Maganizo Omaliza

Kusankha CT sikutanthauza kusankha mlingo waukulu kwambiri "kungofuna kukhala otetezeka." Koma ndikutanthauza kufananiza zenizeni zamagetsi ndi sayansi yoyezera.

Mwa kumvetsetsa momwe kukula kwa CT kumakhudzira kulondola—makamaka pa mafunde otsika—ogwiritsa ntchito amatha kupanga zisankho zodziwikiratu zomwe zimawongolera ubwino wa deta, kudalirika kwa makina, komanso kuzindikira mphamvu kwa nthawi yayitali.

KwaMita yamagetsi yanzeru ya WiFiKusankha bwino CT ndi njira imodzi yothandiza kwambiri yotsimikizira kuti deta yoyezedwa ikuwonetsa momwe mphamvu ikugwiritsidwira ntchito.
