Cov Lus Qhia Uas Sib Tw rau Cov Hloov Hloov Tam Sim No thiab Lub Zog Hluav Taws Xob / Kev Tiv Thaiv
Mastering cov ntsiab lus txuam ntawm cov ntsiab cai tam sim no tsis tuaj yeem txhim kho cov khoom siv tau thiab cov neeg siv khoom ruaj khov thiab thov}} kev txhawb nqa kev txhawb nqa.
Vim li cas thiaj txuam nrog qhov tseem ceeb?
Cov zis ntawm lub teeb liab tam sim no yog qhov ntsuas cov khoom siv tam sim no, thiab lwm yam teeb meem hluav taws xob tsis raug, cov teeb meem hauv qab no yuav tshwm sim:
Overload pheej hmoo: Qhov ntsuas lossis cov cuab yeej tiv thaiv tau yooj yim lossis qhov tseeb txo qis thaum nws ua haujlwm ntev dua nws cov ntaub ntawv rated
Cov Khoom Siv Ingetortion: Tus hloov pauv lub peev xwm tsis txaus ua rau muaj kev tiv thaiv kev tiv thaiv kev ua haujlwm tsis yog, cuam tshuam nrog kev ua haujlwm tsis raug lossis tsis {{} kev ua haujlwm
Kev cuam tshuam raug: Thaum lub nra cuam tshuam
Yog li ntawd, kom ntseeg tau qhov sib txuam ntawm cov peev txheej thib ob los ntawm qhov txuas tseem ceeb uas tsis tuaj yeem tsis quav ntsej hauv txhua lub zog engineering thiab cov cuab yeej siv khoom lag luam
Cov kev tsis tseem ceeb rau tsim nyog sib piv ntawm cov hloov pauv tam sim no thiab lub zog me me
1. Transformer piv (rated thawj / theem nrab tam sim no)
Cov kev hloov pauv yuav tsum raug xaiv kom tau raws li qhov kev ua haujlwm ntau tshaj plaws ntawm lub circuit Court tseem ceeb, thaum noj mus rau hauv tus nqi ntsuas cov twj paj nruag ntawm lub twj paj nruag lossis kev tiv thaiv. Tus txheej txheem theem nrab tam sim no yog 5A lossis 1a.
Cov Lus Taw Qhia: Cov kev hloov pauv kev xaiv sib piv yuav tsum xav txog 1.2 ~ 1.3 npaug ntawm qhov system tam sim no raws li kev nyab xeeb.
2. Theem Qhov Tseeb (xws li 0.2, 0.5, 1, thiab lwm yam)
Cov twj paj nruag sib txawv lossis cov khoom siv sib txawv muaj qhov sib txawv ntawm kev ntsuas qhov raug. Piv txwv li:
Electric zog Electric ntaus: Nws pom zoo kom siv 0.2s, 0.5s siab- precision theem hloov
Qhov ntsuas Ammeter: 1.0 Qib hloov pauv tuaj yeem raug xaiv kom tau raws li kev nyeem txhua hnub
Tshwj xeeb CT rau Kev Tiv Thaiv Ntaus: Siv 5p10, 10p20 thiab lwm theem tiv thaiv, thiab them ntau ntau rau nws qhov tseeb Txwv Alf
Cov Lus Qhia Sib Tham: Cov ntsuas ntsuas qhov tseeb ntau dua lossis sib npaug ntawm kev hloov pauv qib kom tiv thaiv kev hloov pauv hloov pauv ntawm kev ua haujlwm.
3. Rated Load muaj peev xwm (nra)
Chav tsev yog VA (Volt {{{0} ecere ecere ecere ecere), uas qhia tau tias tus hloov pauv tau, thiab xav tau kom phim rau cov khoom sib txuas ntawm cov cuab yeej sib txuas thiab kab.
Piv txwv li: a 5va ct, yog tias tag nrho cov load ntawm Incharing + xaim tshaj li 5VA, nws yuav ua rau tawm tsam kev tawm tsam lossis txo qhov tseeb.
Cov Lus Taw Qhia: Lub kaw lus tag nrho load <80% ntawm CT cov neeg nyob twj ywm thauj khoom, tseg kev tawm tsam kom ntseeg tau cov zis tawm.
Cov kev xav tau tshwj xeeb uas yuav tsum muaj rau cov khoom tiv thaiv
Qhov kev tiv thaiv hluav taws xob yuav tsum tsis txhob tsuas yog qhov tseeb rau cov hloov pauv, tab sis tseem hais tias nws tuaj yeem ua sai sai thiab raug rau hauv huab cua tam sim no.
Xaiv Kev Tiv Thaiv -}} qib transformers transformers (5p / 10p) los tiv nrog kev sib hloov siab tam sim no
Muaj tseeb qhov kev txwv Alf ntau dua los yog sib luag rau qhov kev txhaum ntau tshaj plaws / muaj thawj zaug tam sim no
Theem nrab qhib Circuital tiv thaiv tus qauv tsim los tiv thaiv cov transformer los ntawm qhib cov Circuit Court los ntawm qhib lub Circuit Court los ntawm kev ua haujlwm thiab ua rau muaj kev puas tsuaj
Rau cov neeg xa khoom ntawm high - voltage lossis hnyav {{{{{1} {{1} {} Cov plhaub qhib thiab rwb thaiv tsev kom muaj kev nyab xeeb kom muaj kev nyab xeeb.
