Ihame

Iyo transformateur ya voltage iri mubikorwa bisanzwe, voltage yicyiciro cya gatatu ya sisitemu yingufu irasa, kandi igiteranyo cyibyiciro bitatu byatewe ningufu zitanga amashanyarazi kuri coil ya gatatu ni zeru.Iyo icyiciro kimwe kimaze guhagarara, ingingo idafite aho ibogamiye izimurwa, kandi voltage ya zeru ikurikiranye izagaragara hagati yimpera ya mpandeshatu ifunguye kugirango ikore relay, bityo irinde sisitemu yingufu.Iyo imbaraga za zeru zikurikiranye zigaragara muri coil, zeru zikurikirana za magnetiki flux zizagaragara mugice cyuma gihuye.Kugirango bigerweho, iyi feri ya voltage yicyiciro cya gatatu ifata uruhande rwingogo (iyo 10KV na munsi) cyangwa ibyuma bitatu bya voltage imwe.Kuri ubu bwoko bwa transformateur, ubunyangamugayo bwa coil ya gatatu ntabwo buri hejuru, ariko bisaba ibintu bimwe na bimwe biranga ubukana bukabije (ni ukuvuga, iyo voltage yibanze yiyongereye, ubwinshi bwa magnetiki flux mu cyuma nacyo cyiyongera kuri byinshi bihuye nta byangiritse).

Kuki ukeneye guhindura voltage kumurongo?Ibi ni ukubera ko ukurikije ibihe bitandukanye byo kubyara amashanyarazi, guhererekanya no gukoresha amashanyarazi, voltage kumirongo iratandukanye mubunini, kandi itandukaniro riratandukanye cyane.Bimwe ni voltage nkeya 220V na 380V, naho zimwe ni voltage nini ibihumbi icumi bya volt cyangwa ibihumbi magana ya volt.Kugirango upime mu buryo butaziguye ayo mashanyarazi make na voltage nini cyane, birakenewe gukora voltage ihwanye na voltage nini cyane hamwe nibindi bikoresho hamwe na relay ukurikije ubunini bwumurongo wa voltage.Ibi ntibizazana gusa ingorane zikomeye mugukora igikoresho, ariko cyane cyane, ntibishoboka kandi birabujijwe rwose gukora igikoresho cyumubyigano mwinshi no gupima voltage kumurongo wa voltage.

Kwirinda

1. Mbere yuko transformateur ya voltage itangira gukoreshwa, ikizamini nubugenzuzi bigomba gukorwa hakurikijwe ibintu bivugwa mumabwiriza.Kurugero, gupima polarite, itsinda ryihuza, guhinda umushyitsi, icyiciro cya kirimbuzi, nibindi.

2. Gukoresha insimburangingo ya voltage bigomba kwemeza neza.Ihinduranya ryibanze rigomba guhuzwa hamwe nu muzunguruko uri kugeragezwa, naho guhinduranya kwa kabiri bigomba guhuzwa hamwe na coil ya voltage igikoresho cyo gupima, igikoresho cyo gukingira ibyuma cyangwa ibikoresho byikora.Muri icyo gihe, hagomba kwitonderwa ukuri kwa polarite..

3. Ubushobozi bwumutwaro uhujwe kuruhande rwa kabiri rwa transformateur ya voltage igomba kuba ikwiye, kandi umutwaro uhujwe kuruhande rwa kabiri rwa transformateur ya voltage ntugomba kurenza ubushobozi bwarwo, naho ubundi, ikosa rya transformateur riziyongera, kandi biragoye kugera kubwukuri bwo gupima.

4. Nta muyoboro mugufi wemerewe kuruhande rwa kabiri rwa transformateur ya voltage.Kubera ko inzitizi y'imbere ya transformateur ya voltage ari nto cyane, niba umuzunguruko wa kabiri ari umuzunguruko mugufi, umuyoboro munini uzagaragara, uzangiza ibikoresho bya kabiri ndetse uhungabanya umutekano bwite.Impinduka ya voltage irashobora gushyirwamo fuse kuruhande rwa kabiri kugirango yirinde kwangizwa numuyoboro mugufi kuruhande rwa kabiri.Niba bishoboka, fus igomba kandi gushyirwaho kuruhande rwibanze kugirango irinde umuyagankuba mwinshi w'amashanyarazi kutabangamira umutekano wa sisitemu y'ibanze kubera kunanirwa kwa transformateur ya voltage nini cyangwa insinga ziyobora.

5. Kugirango habeho umutekano wabantu mugihe bakora ku bikoresho bipima na relay, guhinduranya kwa kabiri kwa transformateur ya voltage bigomba guhagarara kumwanya umwe.Kuberako nyuma yo guhaguruka, mugihe insulasiyo iri hagati yicyiciro cya mbere nicyiciro cya kabiri yangiritse, irashobora gukumira umuyaga mwinshi wigikoresho hamwe na relay kubangamira umutekano wumuntu.

6. Inzira ngufi ntizemewe rwose kuruhande rwa kabiri rwa transformateur ya voltage.
