Umbuzo 1) iyini i-instrument transformer?

Uma sifuna ukukala amanani aphezulu kakhulu kagesi kanye ne-voltage kunezindlela ezimbili zokukala. Enye ukusebenzisa amathuluzi anomthamo ophezulu okungaba kubi kakhulu. Enye indlela ukusebenzisa i-transformation property yamandla kagesi kanye ne-voltage.

Ugesi kanye ne-voltage kungancishiswa ngokusebenzisa i-transformer eyaziwa ngokuthi isilinganiso sokujika bese kulinganiswa ugesi kanye ne-voltage encishisiwe nge-ammeter noma i-voltmeter evamile. Ubukhulu bokuqala bunganqunywa ngokuphindaphinda ubukhulu bokwehla ngesilinganiso sokujika. I-transformer enjalo eyakhiwe ngokukhethekile enesilinganiso sokujika esinembile ibizwa ngokuthi i-instrument transformer. Kunezinhlobo ezimbili ze-instrument transformer:

1) I-transformer yamanje

2) I-transformer engaba khona.

Umbuzo 2) ayini ama-transformer amanje?

I-transformer yamanje ifakwa ochungechungeni nomugqa lapho kuzolinganiswa khona ugesi. Isetshenziselwa ukwehlisa ugesi uye ezingeni elinjalo ukuze ukwazi ukukalwa kalula ngokusebenzisa i-ammeter. Ngokuvamile ivezwa njengesilinganiso samanje esiyinhloko: sesibili sesibonelo: I-CT engu-100:5 amp izoba nogesi oyinhloko wama-Amp ayi-100 kanye nogesi wesibili wama-Amp ayi-5.

Isilinganiso sesibili esijwayelekile sama-CT singama-5 noma ama-1 Amp

Ukusetshenziswa okuvamile kwe-CT emakethe yi-“clamp meter”.

Umbuzo 3) ziyini iziguquli ezingaba khona?

Ama-transformer angaba khona aziwa nangokuthi ama-voltage transformer futhi empeleni angama-step down transformer anesilinganiso sokujika esinembile kakhulu. Ama-potential transformer anciphisa i-voltage yobukhulu obuphezulu aye ku-voltage ephansi engalinganiswa ngethuluzi lokulinganisa elijwayelekile. Lawa ma-transformer anenani elikhulu lama-primary turns kanye nenani elincane lama-secondary turns.

I-transformer engaba khona ivame ukuvezwa ngesilinganiso se-voltage yokuqala neyesibili. Isibonelo, i-PT engu-600:120 ingasho ukuthi i-voltage kuyo yonke i-secondary ingu-120 volts lapho i-voltage yokuqala ingu-600 volts.

Umbuzo 4) yini umehluko phakathi kwe-current kanye ne-power transformer?

Ezingeni eliyisisekelo, azihlukile. Zombili zisebenza ngesimiso sokungeniswa kwe-electromagnetic. Kodwa umehluko usekusetshenzisweni kwazo.

Ama-transformer amanje, angaphansi kwesigaba sama-Instrument transformers, asetshenziswa kakhulu kanye nezinye izinsimbi ngenhloso yokulinganisa. Njenganoma iyiphi enye ithuluzi esetshenziselwa ukulinganisa kumasekethe kagesi, ama-transformer amanje kumele abe ne-impedance ephansi kakhulu ukuze angathinti ugesi osesekethe eliwulinganisayo ngenani elikhulu. Futhi kubaluleke kakhulu ukuqinisekisa ukuthi umehluko wesigaba phakathi kogesi oyinhloko nowesibili useduze no-zero ngangokunokwenzeka. I-transformer yamanje nayo inokushintsha okuncane kakhulu, noma ngisho nokujika okukodwa kugesi oyinhloko kanye nokuningi kugesi oyinhloko.

Ngakolunye uhlangothi, ama-Power transformer asetshenziselwa ukudlulisa amandla kusuka ohlangothini oluyinhloko kuya ohlangothini lwesibili. Lapha kugxilwe kakhulu ekunciphiseni i-impedance ku-transformer, futhi akugxili kakhulu ekunciphiseni iphutha le-phase angle eliseduze no-zero. Lapha kugxilwe kakhulu ekusebenzeni kahle kunokunemba. Okwesibili, i-power transformer inamajika amaningi kakhulu ku-primary yayo, kunokujika okukodwa, yize isencane kunaleyo e-secondary.

Umbuzo 5) Yimuphi umshini ongakhiqiza i-transformer yamanje kanye ne-transformer engaba khona?

Kunezindlela ezimbili zobuchwepheshe zokufaka i-epoxy resin current transformer, endala kanye neyakudala isetshenziswa ngethangi lokukhipha i-vacuum, elibizwa ngokuthi i-vacuum casting tank. ubuchwepheshe bokuphonsa nge-vacuum, Ubuchwepheshe besibili bamuva bungu Ubuchwepheshe be-APG (i-automatic pressure gelation) ,Umshini wokuphonsa uwumshini wokubopha we-APG,obizwa nangokuthi umshini we-APG,umshini we-epoxy resin apg,Manje umshini we-APG uwukukhetha kokuqala kwabasebenzisi.Ngenxa yezinzuzo ezingezansi:

1. Ukusebenza Kahle Kokukhiqiza, Thatha umkhiqizo we-10KV CT njengesibonelo, ungathola i-CT efanelekile zingakapheli imizuzu engama-30.
2. Ukutshalwa kwezimali，Intengo yomshini we-APG cishe i-55000-68000USD
3. Ukufakwa, kudingeka ukuxhuma kagesi kuphela, bese kusetshenziswa umshini
4. Ukusebenza kukagesi, ukukhishwa kwengxenye, ukumelana namakhemikhali, ukufakelwa kukagesi, ukumelana namandla kuthuthuke kakhulu, sinemishini yokuhlola esisebenza nayo.
5. Izinga Lokwenza Izinto Ngokuzenzakalelayo: Kudingeka abasebenzi abangu-1-2 kuphela abazosebenzisa umshini, ukusebenza kahle kukhushulwa kakhulu kodwa amandla abasebenzi ayancipha. Kudingeka okhiye bokulawula kuphela kukhabhinethi yamandla.
6. Ukusebenza, Kulula ukusebenzisa umshini we-APG, unjiniyela wethu uzokukhombisa ukuthi ungawusebenzisa kanjani futhi sinencwadi yomsebenzisi yokuqondisa ukusebenza komshini wethu, asikho isidingo sokukhokha imali ephezulu ukuze uqashe onjiniyela abangochwepheshe ukuze basebenzise umshini.
