Inyigisho yo Guhitamo Igipimo cy'Ingufu cya WiFi Smart Energy Meter CT: Uburyo bwo Guhitamo Igikoresho Gikwiye

Intangiriro: Impamvu guhitamo CT ari ingenzi mu gupima ingufu za WiFi

Mu gihe cyo gushyirahoIgipimo cy'ingufu cya WiFi gikoresha ikoranabuhanga rigezweho, abakoresha benshi bibanda ku guhuza, porogaramu za mudasobwa, cyangwa guhuza porogaramu mu bicu. Ariko, hari igice cy'ingenzi gikunze gusuzugurwa:transformateur y'amashanyarazi (CT clamp).

Guhitamo amanota mabi ya CT bishobora kugira ingaruka zitaziguye ku buryo ibipimo bipima neza—cyane cyane iyo umutwaro uri hasi. Niyo mpamvu ibibazo nk'ibi bikurikira:"Ese nahitamo 80A, 120A, cyangwa 200A CTs?" or "Ese CT nini izakomeza kuba nyayo ku miyoboro mito?"bikunze kugaragara mu gihe cyo gutegura imishinga.

Iyi mfashanyigisho isobanura uburyo CT clamps zikora, impamvu ingano ikwiye ari ingenzi, n'uburyo bwo guhitamo urwego rukwiye rwa CT mu kugenzura ingufu mu buryo bufatika—ikoresheje ingero zifatika zishingiye ku bipimo bya WiFi nka PC321.

Uburyo CT Clamps zipima umuriro mu bipimo by'ingufu bya WiFi

Igikoresho cya CT gipima umuvuduko w'amashanyarazi binyuze mu kumenya imbaraga rukuruzi zikorwa n'umuyoboro w'amashanyarazi. Hanyuma ikimenyetso cyapimwe gihindurwamo umuvuduko w'amashanyarazi wagabanutse ushobora gupimwa n'ikimenyetso cy'ingufu.

Buri kampane ya CT ikozwe hamwe n'uburyoingano y'amashanyarazi, nka 80A, 120A, cyangwa 200A. Iri suzuma rigena urwego CT ikoramo neza mu buryo bwemejwe mu gihe cy’ibizamini bisanzwe.

Icy'ingenzi ni uko uburyo bwo gukoresha CT neza butari bumwe mu buryo busanzwe—biterwa n'uburyo amashanyarazi nyayo akoreshwa hafi y'amashanyarazi ya CT.

Gusobanukirwa amanota y'ubuziranenge bwa CT n'uburyo bwo gukora

Udukoresho twinshi twa CT clamps two gupima dukoreshwa mu bipimo by’ingufu bigezweho dukurikiza amahame y’ubunyangamugayo yo mu cyiciro cya 1.0.

Ubunyangamugayo busobanurwa mu rugero runaka rw'umuvuduko w'amashanyarazi, ubusanzwe kuva kuri 5% kugeza 100% by'umuvuduko w'amashanyarazi, nk'uko bivugwa mu bipimo mpuzamahanga ku byuma bihindura amashanyarazi (urugero,IEC 61869).

Muri uru rwego, CT ishobora kugera ku±Ubuziranenge bwa 1% mu gupima hakurikijwe ibipimo bisanzwe.

Urugero:

A 200A CTikomeza gukoresha neza Class 1.0 uhereye hafiKuva kuri 10A kugeza kuri 200A
A 40A CTigumana ubunyangamugayo bumwe kuva hafiKuva kuri 2A kugeza kuri 40A

Ibi bisobanura impamvu ingano ya CT igira ingaruka zitaziguye ku mikorere y'ibipimo by'amashanyarazi make.

Bigenda bite iyo CT nini ipima umuyoboro muto w'amazi?

Ikibazo gikunze kugaragara ni ukumenya niba200A CT ishobora gupima neza umutwaro wa 40AIgisubizo kigufi ni iki:yego, bizagenda neza—ariko bishobora kuba atari byiza cyane.

Impamvu ubunyangamugayo bushobora kugabanuka ku rugero rwo hasi rw'amashanyarazi

Iyo CT ibaye nini cyane:

Ikimenyetso cya kabiri kiba gito cyane iyo umuvuduko w'amazi uri hasi
Ubushobozi bwo gupima buragabanuka
Ikosa ry'urusaku n'ikosa ry'icyiciro rirushaho kugaragara
Ingufu nke n'umutwaro muto w'imbaraga zikoreshwa mu gupima amashanyarazi birushaho kugira ingaruka mbi

Nubwo CT ishobora kuba igifite ibisabwa byo mu cyiciro cya 1.0 mu gihe habayeho imiterere ya laboratwari,gushyiraho ibintu mu buryo bufatika—hamwe n'urusaku rw'amashanyarazi, imizigo idahindagurika, n'imigezi ihindagurika—bishobora kugabanuka ku buryo umutwaro muto utoroshye.

Iyi ni yo mpamvu CT zingana hafi y'umuvuduko w'imikorere nyayo muri rusange zitangagukoresha neza ibintu mu buryo bufatika, nubwo CT zombi zaba zujuje icyiciro kimwe cy’ubunyangamugayo.

Uburyo bwiza: Uburyo bwo guhitamo amanota meza ya CT

Intambwe ya 1: Kumenya umuvuduko ntarengwa witezwe

Koresha kimwe muri ibi bikurikira:

Igipimo cy'umuvuduko w'uruziga
Imashini zikoresha izina ry'umuyoboro w'amashanyarazi
Amakuru y'amateka y'imitwaro (niba ahari)

Intambwe ya 2: Shyira mu bikorwa itegeko rifatika ryo gupima ingano

Amabwiriza y’ubuhanga yemerwa cyane ni:

Umuvuduko wa CT ufite amanota ≈ 1.2–1.5 × umuvuduko ntarengwa w’amashanyarazi witezwe

Ubu buryo butanga:

Ingano ihagije yo gutwara ibintu byinshi
Ubushobozi bwiza mu gihe cy'imikorere isanzwe
Imyitwarire yo gupima umuriro muke yarushijeho kuba myiza

Guhitamo CT bisanzwe mu bijyanye no gutura no mu bucuruzi

Hashingiwe ku bunararibonye nyakuri bwo gutanga serivisi hamweIbipimo bya WiFi bikoresha ubwengenka PC321:

Ibikoresho byo kubaka amazu

80A CT: Bikwiriye amazu mato cyangwa imiyoboro y'amashanyarazi make
120A CT: Ikoreshwa cyane mu ngo zo muri Amerika y'Amajyaruguru, itanga uburinganire bwiza hagati yo gukingira no gukoresha neza imizigo mito.

Ibikoresho by'ubucuruzi

200A CT: Isanzwe ikoreshwa mu byuma byoroheje by'ubucuruzi n'inganda nto
CT 300A cyangwa irenga: Ikoreshwa iyo ingano y'insinga cyangwa kwaguka mu gihe kizaza bisaba ko umutwe w'inyongera ushyirwamo

Mu by’ukuri, abakoresha benshi bahitamo gukoresha uburyo bubiri bwa CT—bumwe bwo mu ngo n’ubundi bwo mu bucuruzi—kugira ngo byorohereze ububiko n’uburyo bwo kubukoresha.

Ingano y'insinga n'umurambararo w'idirishya rya CT: Imbogamizi Ifatika

Guhitamo CT ntabwo ari ibijyanye n'amanota agezweho gusa.Umurambararo w'insinga ugomba kwinjira neza unyuze mu idirishya rya CT.

Urugero:

Imashini ntoya zo mu bwoko bwa CT zishobora gutanga uburyo bwiza bwo gukoresha ingufu nke
CT nini zitanga uburyo bwagutse bwo guhuza insinga no koroshya kuyishyiraho

Iyi mbogamizi ya tekiniki ikunze kugira ingaruka ku guhitamo CT ndetse no ku bijyanye n'amashanyarazi.

Owon PC321 nk'urugero rufatika rw'uburyo bwo guhitamo CT

ItsindaIgipimo cy'ingufu cya PC321 WiFi gikoresha ingufu zigezwehoIshyigikira ubwoko bwinshi bw'udukingirizo twa CT dushobora guhindurwa. Ubu buryo bworoshye butuma abashushanya sisitemu bahindura uburyo bwo guhitamo CT hashingiwe kuri:

Kura umwirondoro
Ahantu ho gushyira ibintu
Ibisabwa kugira ngo habeho ubunyangamugayo
Ibipimo by'insinga

Byongeye kandi, gupima urwego rw'imikorere hagati ya metero n'ibikoresho bya CT bifasha kwemeza imikorere yizewe yo gupima mu byiciro bitandukanye bya CT.

Ese Calibration ishobora kwishyura CT nini cyane?

Gupima bishobora kunoza uburyo sisitemu ikora neza, arikontibishobora gukuraho burundu imbogamizi zigaragara za CT nini cyaneku muvuduko w'amazi uri hasi cyane.

Nubwo gupima uruhande rwa metero no kwishyurana hakoreshejwe ikoranabuhanga bifasha:

Imipaka yo gukoresha ibimenyetso ku rusaku iracyakurikizwa
Ikosa rya phase ku muvuduko muto w'amashanyarazi rikomeje kuba intandaro

Bityo rero,Gupima neza CT bikomeje kuba uburyo bwiza bwo kugera ku bipimo bihamye kandi nyabyo.

Ingingo z'ingenzi zo guhitamo CT

CT nini zishobora gupima imiyoboro mito, ariko ubushishozi bw'umutwaro muke bushobora kugabanuka
Ubuhanga bwa CT bwemezwa gusa mu ijanisha ryagenwe ry'umuvuduko w'amashanyarazi
Guhitamo CT yegereye aho ikoreshwa by’ukuri binoza uburyo bwo gukora ibintu mu buryo bufatika
Imiterere y'ibikoresho n'uburyo bishyirwamo ni ingenzi kimwe n'uko amashanyarazi akoreshwa.
Uburyo bworoshye bwo gukoresha CT, nk'ubufashwa na PC321, bworoshya uburyo bwo kunoza sisitemu

Ibitekerezo bya nyuma

Guhitamo CT ntabwo ari uguhitamo amanota menshi "kugira ngo ube mu mutekano gusa." Ahubwo ni uguhuza ukuri kw'amashanyarazi na fiziki yo gupima.

Mu gusobanukirwa uburyo ingano ya CT igira ingaruka ku buryo buboneye—cyane cyane iyo umuvuduko uri hasi—abakoresha bashobora gufata ibyemezo bifatika binoza ireme ry’amakuru, uburyo bwo kwizera sisitemu, ndetse n’ubumenyi bw’igihe kirekire ku ngufu.

KuriIbipimo by'ingufu bya WiFi bigezwehoGuhitamo neza CT ni bumwe mu buryo bwiza bwo kwemeza ko amakuru yapimwe agaragaza koko uburyo ingufu zikoreshwa.
