Gwaro Rekusarudza WiFi Smart Energy Meter CT: Maitiro Ekusarudza Chinovhara Chakakodzera Kuti Uyere Zvakakwana

Nhanganyaya: Nei Kusarudzwa kweCT Kuchikosha MuWiFi Smart Energy Metering

Pakuisa aWiFi smart energy meter, vashandisi vazhinji vanonyanya kutarisa pakubatana, mapuratifomu esoftware, kana kubatanidzwa kwegore. Zvisinei, chimwe chinhu chakakosha chinowanzo shorwa pasi:transformer yemazuva ano (CT clamp).

Kusarudza CT rating isiriyo kunogona kukanganisa zvakananga kurongeka kwekuyera—kunyanya kana mutoro wakaderera. Ndosaka mibvunzo yakaita sekuti"Ndinofanira kusarudza 80A, 120A, kana 200A CTs here?" or "Ko CT yakakura icharamba yakarurama here pamafungu madiki?"zvinowanzoitika panguva yekuronga mapurojekiti.

Gwaro iri rinotsanangura mashandiro anoita maCT clamps, nei saizi yakakodzera ichikosha, uye kuti ungasarudza sei CT range yakakodzera yekutarisa simba remagetsi—uchishandisa mienzaniso inoshanda yakavakirwa pamaWiFi smart meters akadai sePC321.

Maitiro eCT Clamps Anoyera Sei Current muWiFi Energy Meters

Chinovhara CT chinoyera magetsi nekuona simba remagineti rinogadzirwa neconductor. Chiratidzo chakayerwa chinozoshandurwa kuita magetsi echipiri akadzikiswa anogona kugadziriswa ne energy meter.

Chikamu chega chega cheCT chakagadzirwa neyakayerwa ikozvino, zvakaita se80A, 120A, kana 200A. Chiyero ichi chinotsanangura huwandu hunoshanda neCT nemazvo pasi pemamiriro ebvunzo akajairwa.

Chinonyanya kukosha ndechekuti, kururama kweCT hakuna kufanana muhuwandu hwese—zvinoenderana nekuti simba rekushanda riri pedyo zvakadii nesimba reCT.

Kunzwisisa CT Accuracy Ratings uye Operating Ranges

Ma CT clamps mazhinji emhando yekuyera anoshandiswa muma smart energy meter anotevedzera mwero weKirasi 1.0 wekunyatsorurama.

Kururama kunotsanangurwa mukati mehuwandu hwemagetsi ekushanda, kazhinji kubva pa5% kusvika ku100% yemagetsi akayerwa, sezvakatsanangurwa mumitemo yepasi rose yemagetsi ekushandura zvishandiso (semuenzaniso,IEC 61869).

Mukati meiyi nzira, CT inogona kuwana±Kunyatsojeka kwekuyera kwe1% pasi pemamiriro ekuyedza akajairwa.

Semuyenzaniso:

• A 200A CTinochengetedza kururama kweKirasi 1.0 kubva paanenge10A kusvika 200A

• A 40A CTinochengetedza kururama kwakafanana kubva paanenge2A kusvika 40A

Izvi zvinotsanangura kuti nei saizi yeCT ichikanganisa zvakananga mashandiro ekuyera kwesimba remagetsi risingashande zvakanyanya.

Chii Chinoitika Kana CT Yakakura Ikayera Mwenje Mudiki?

Mubvunzo unowanzo bvunzwa ndewekuti200A CT inogona kuyera mutoro we40A nemazvoMhinduro pfupi ndeiyi:hongu, zvichashanda—asi zvingasava zvakanaka.

Sei kururama kuchigona kudzikira padanho rakaderera remagetsi

Kana CT yakakura zvakanyanya:

• Chiratidzo chechipiri chinova chidiki zvikuru kana magetsi akaderera

• Kuyera kwechiyero kunoderera

• Ruzha uye kukanganisa kwechikamu zvinoonekwa zvakanyanya

• Simba shoma uye mutoro wesimba shoma zvinokanganiswa zvakanyanya

Kunyange zvazvo CT ingave ichiri kusangana nezvinodiwa zveKirasi 1.0 pasi pemamiriro emurabhoritari,kuiswa kwenyika chaiyo—neruzha rwemagetsi, mitoro isina kurongeka, uye mafungu anochinja-chinja—anogona kuwana kuderera kwekunyatsorongeka kwemitoro yakaderera.

Ndosaka maCT akakura ari pedyo nekushanda kwemagetsi chaiwo achiwanzopakunyatsoshanda kuri nani, kunyangwe kana maCT ese ari maviri achisangana nekirasi imwechete yekunyora accuracy.

Maitiro Akanakisisa: Maitiro Ekusarudza CT Rating Yakakodzera

Danho 1: Ziva huwandu hwemagetsi hunotarisirwa

Shandisa chimwe chezvinotevera:

• Kuyera kwecircuit breaker

• Chishandiso chezita remagetsi

• Ruzivo rwekare rwemutoro (kana rwuripo)

Danho rechipiri: Shandisa mutemo unoshanda wehukuru

Gwaro remainjiniya rinogamuchirwa nevakawanda nderinoti:

CT yakayerwa magetsi ≈ 1.2–1.5 × simba rekushanda rinotarisirwa

Nzira iyi inopa:

• Margin yakakwana yekutakura zvinhu zvakanyanya

• Kugadziriswa kuri nani panguva yekushanda kwakajairika

• Maitiro ekuyera ane simba shoma akavandudzwa

Sarudzo Yakajairika yeCT yeZvikumbiro zveDzimba neZvemabhizinesi

Zvichibva paruzivo rwechokwadi rwekutumirwa kwedataWiFi smart metresdzakadai sePC321:

Kuisa dzimba

• 80A CT: Yakakodzera dzimba diki kana macircuit ane simba shoma

• 120A CT: Inonyanya kushandiswa kudzimba dzekuNorth America, zvichipa chiyero chakanaka pakati pekufukidza uye kunyatsoreruka kwemutoro.

Kuisa kwekutengeserana

• 200A CT: Zvakajairika pamidziyo yekudyisa yemabhizimisi midiki uye yekutengeserana

• CTs 300A kana kupfuura: Inoshandiswa kana saizi yetambo kana kuwedzera kweramangwana kuchida imwe nzvimbo yemusoro

Muchokwadi, vashandisi vazhinji vanosarudza kushandisa nzira mbiri dzeCT — imwe yekugara uye imwe yekutengeserana — kuitira kuti zvinhu zviri mudura zvive nyore uye kuti zvishandiswe.

Saizi yeCable neDiameter yeCT Window: Chipingamupinyi Chinoshanda

Kusarudzwa kweCT hakusi kwekungotarisa pari zvino chete.Dhayamita yetambo inofanira kukwana nepahwindo reCT.

Semuyenzaniso:

• MaCT madiki anogona kupa kunyatsojeka kuri nani kwesimba remagetsi risingashande

• MaCT makuru anopa tambo dzakakura dzinoenderana uye zviri nyore kuisa

Dambudziko iri remakanika rinowanzo kanganisa sarudzo yeCT pamwe nepfungwa dzemagetsi.

Owon PC321 seMuenzaniso Unoshanda weKusarudza CT

IyoPC321 WiFi smart energy meterinotsigira mhando dzakasiyana dzema CT clamps anochinjika. Kuchinjika uku kunobvumira vagadziri vemasystem kugadzirisa sarudzo yeCT zvichienderana ne:

• Rodha purofiti

• Nzvimbo yekuisa

• Zvinodiwa zvekururama

• Zviyero zvetambo

Pamusoro pezvo, kuyera nhanho yesystem pakati pemita neCT clamps kunobatsira kuona kuti kuyerwa kweCT kwakavimbika.

Kugadzirisa Kukwanisa Kutsiva MaCT Akakura Here?

Kugadzirisa kunogona kuvandudza kururama kwehurongwa hwese, asihaigone kubvisa zvizere miganhu yemuviri yeCTs yakakurapamvura yakadzika kwazvo.

Kunyange zvazvo kuyera mativi emita uye muripo wedhijitari zvichibatsira:

• Miganhu yekuratidza ruzha ichiri kushanda

• Kukanganisa kwechikamu panguva yemagetsi akaderera kunoramba kuri chinhu chinokonzera

Naizvozvo,saizi chaiyo yeCT ndiyo nzira inoshanda kwazvo yekuwana zviyero zvakagadzikana uye zvakarurama.

Zvinhu Zvikuru Zvekusarudza CT

• MaCT makuru anogona kuyera ma currents madiki, asi kunyatsoita basa remutoro wakaderera kunogona kudzikira

• Kururama kweCT kunovimbiswa chete mukati mechikamu chakatsanangurwa chemagetsi akaongororwa

• Kusarudza CT iri pedyo nenzvimbo chaiyo yekushanda kunovandudza kururama kwenyika chaiyo

• Kukwana kwemuchina uye mamiriro ekuisa zvinhu zvakakosha sekushandiswa kwemagetsi

• Sarudzo dzeCT dzinochinjika, dzakadai sedzinotsigirwa nePC321, dzinorerutsa kugadziriswa kwesystem

Pfungwa Dzekupedzisira

Kusarudzwa kweCT hakusi kwekusarudza chiyero chikuru "kungochengeteka." Kunosanganisira kufananidza chokwadi chemagetsi nefizikisi yekuyera.

Nekunzwisisa kuti saizi yeCT inokanganisa sei kururama—kunyanya pamagetsi akaderera—vashandisi vanogona kuita sarudzo dzakagadzirwa neruzivo dzinovandudza kunaka kwedata, kuvimbika kwesystem, uye ruzivo rwesimba kwenguva refu.

ZveWiFi smart energy metres, kusarudza CT kwakakodzera ndeimwe yenzira dzinoshanda kwazvo dzekuona kuti data rakayerwa rinoratidza mashandisirwo esimba riri kuitwa.
