Momwe mungathanirane ndi cholakwika cha transformer yamakono?

Katundu wachiwiri wa transformer yamakono imakhudza mwachindunji ntchito yake yolondola.Nthawi zambiri, katundu wachiwiri akachuluka, ndiye kuti cholakwika cha thiransifoma chimakhala chachikulu.Malingana ngati katundu wachiwiri sakupitirira mtengo wokhazikitsidwa ndi wopanga, wopanga ayenera kuonetsetsa kuti cholakwika chopangidwa ndi thiransifoma chili mkati mwa mulingo wake wolondola kapena mkati mwa 10% yokhota zolakwika.Mkati.Choncho, pakugwiritsa ntchito thiransifoma yamakono, katundu wake wachiwiri wovomerezeka ndi katundu weniweni wachiwiri ayenera kudziwika.Pokhapokha pamene katundu wachiwiri weniweni ndi wocheperapo kusiyana ndi katundu wachiwiri wovomerezeka akhoza kulakwitsa kukwaniritsa zofunikira.

Pamene cholakwika cha thiransifoma yamakono chikuposa mtengo wotchulidwa wa wopanga, zidzakhala ndi zotsatira zoipa pa zipangizo zachiwiri monga chitetezo cha relay ndi zipangizo za metering.Njira zolipirira zomwe ziyenera kuchitidwa pamene cholakwika cha thiransifoma yamakono chikuposa mtengo wotchulidwa wa wopanga.

(1) Wonjezerani malo ozungulira chingwe chachiwiri kapena kuchepetsa kutalika kwa chingwe.Kuwonjezeka kwa gawo lachigawo cha chingwe chachiwiri chachitsulo chamakono kapena kuchepetsa kutalika kwa chingwe kwenikweni kumachepetsa kutsekeka kwa waya wachiwiri ndikuchepetsa katundu wachiwiri.

(2) Lumikizani koyilo yachiwiri ya thiransifoma yosunga zosunga zobwezeretsera mndandanda kuti muwonjezere katunduyo.Ma coil achiwiri a ma transfoma omwe ali mu gawo lachiwiri omwe ali ndi chiŵerengero chofanana cha kusintha ndi makhalidwe omwewo amagwiritsidwa ntchito mndandanda.

(3) Wonjezerani chiŵerengero cha kusintha kwa thiransifoma yamakono kapena kugwiritsa ntchito thiransifoma yamakono ndi yachiwiri yomwe ili ndi chiwerengero cha 1A.Malinga ndi mfundo yakuti kutayika kwa mzere kumakhala kofanana ndi malo omwe alipo panopa, zikhoza kuwoneka kuti kutayika kwa mzere kumakhala kochepa ndipo mphamvu yotulutsa mpweya imakhala yaikulu, kotero mphamvu yonyamula katundu imalimbikitsidwa.

(4) Chepetsani katundu wachiwiri.Sankhani relay yokhala ndi mawonekedwe akulu momwe mungathere, chifukwa waya wam'mimba mwake wa koyilo yopatsirana yokhala ndi mawonekedwe akulu apano ndi wandiweyani ndipo kuchuluka kwa matembenuzidwe kumakhala kochepa, kotero kuti kutsekeka kumakhala kochepa;kapena sinthani kugwirizana kwa mndandanda wa koyilo yopatsirana ku kulumikizana kofananira, chifukwa kutsekeka kwa mndandanda wamalumikizidwe The impedance ndi yayikulu kuposa kulumikizana kofananira;kapena gwiritsani ntchito chipangizo choteteza ma microcomputer kuti mulowe m'malo mwa electromagnetic relay.

Kuyesa kwa insulation kukana kwa thiransifoma yamakono

1. Cholinga cha mayeso

Itha kupeza bwino zolakwika zonse zotsekereza, monga chinyontho, dothi, kulowa, kuwonongeka kwa insulation, ndi zina zambiri, komanso kutenthedwa kwakukulu ndi kukalamba.Kuyeza kukana kwa kutchinjiriza kwa chishango chomaliza pansi kumatha kuzindikira bwino kulowera kwa madzi ndi kuwonongeka kwa chinyezi cha capacitive current transformer.

2. Kuyesa kuchuluka

Kuyeza kukana kwa kutchinjiriza kwa mapindikidwe a pulayimale ku mapindikidwe achiwiri ndi posungira, ndi kukana kwa insulation ya mafunde achiwiri ndi casing.

Kuyeza kukana kwa kutchinjiriza pakati pa zigawo zoyambira zomangirira, koma sikoyenera kuyeza ngati sikungayesedwe chifukwa cha zifukwa zamapangidwe.

Yezerani kukana kwa kutchinjiriza kwa gawo lomaliza la chishango cha capacitive current transformer.

3. Kusankha zida

Yesani kukana kwa kutchinjiriza pakati pa kusungunula kwakukulu kwa thiransifoma yamakono, chishango chomaliza, mafunde achiwiri ndi pansi.Insulation resistance tester ya 2500V ndi pamwambapa iyenera kugwiritsidwa ntchito poyesa kukonza kapena kupereka ndi kuyesa kodziletsa.

4. Kusanthula kwachiwopsezo ndi njira zowongolera

kuteteza kugwa kuchokera pamwamba

Pewani kuvulala kuzinthu zakugwa

kuteteza kugwedezeka kwamagetsi

Asanatuluke ndikulumikiza mzere woyeserera, chosinthira chomwe chikuyesedwa chiyenera kutayidwa pansi kuti chiteteze chotsalira komanso ma voliyumu opangitsa kuti asawononge anthu komanso kukhudza zotsatira zake.Chophimba chachitsulo cha chida choyesera chiyenera kukhala chokhazikika, ndipo woyesa yemwe akugwiritsa ntchito chipangizocho ayenera kuyima pa insulating pad kapena kuvala slash yotetezera kuti agwiritse ntchito chidacho.Zibalo zoyeserera ziyenera kulumikizidwa ndi munthu amene akuyang'anira, ndipo kuphatikizika sikuloledwa.

Khazikitsani malo otsekedwa otsekedwa mozungulira malo oyesera, pachikani zizindikiro za "stop, high voltage risk", ndi kulimbikitsa kuyang'anitsitsa.Limbikitsani kuyang'anira ndikukhazikitsa njira yoyimba yomwe ikugwira ntchito.

5. Kukonzekera mayeso asanalembe

Kumvetsetsa momwe zinthu zilili m'munda ndi mayeso a zida zomwe zikuyesedwa.

Malizitsani zida zoyesera ndi zida

Tengani chitetezo ndi njira zaukadaulo pamalo oyeserera

Oyesa mabokosi afotokoze zomwe zili mu ntchito, magawo omwe akukhalapo, njira zotetezera pamalopo, malo owopsa ogwirira ntchito pamalowo, ndikufotokozeranso kagawidwe ka ntchito ndi mayeso.

6. Njira zoyeserera zakumunda ndi zofunikira

Yang'anani megohmmeter yokha musanayambe kuyesedwa, ikani mlingo wa megohmmeter mokhazikika, kuyesa koyamba kwafupipafupi ndiyeno kuyesedwa kwapakati, pamene kulumikizidwa ndi magetsi a megohmmeter yokonzedwanso, waya wa Uno adzakhala wozungulira "L" ndi “E”” pothera, chisonyezerocho chikhale ziro; ikayatsidwa, mphamvu ikayatsidwa kapena liwiro lovotera likuwonetsedwa ndi ma megohm, chizindikirocho chikhale “∞”. ndiyeno gwirizanitsani malo okwera magetsi.

Terminal "E" pa megohmmeter ndi poyambira pansi pa chinthu choyesera, chomwe ndi mtengo wabwino, ndipo "L" ndi malo okwera magetsi opangira mayeso, omwe ndi mzati wopanda pake."G" imalumikizidwa ndi chotchinga chotchinga, chomwe ndi mzati wopanda pake.

7. Kuyesa kwa insulation resistance

Yezerani kukana kwa kutchinjiriza kwa mapindikidwe oyambira a thiransifoma yamakono kupita kumayendedwe apachiwiri ndi chipolopolo

Yesani kukana kwa kutchinjiriza pakati pa mafunde achiwiri a thiransifoma yamakono ndi pansi

Kuyeza kukana kwa kutchinjiriza kwa chishango chomaliza cha thiransifoma yamakono

Kuyeza kukana kwa insulation ya mapindikidwe oyamba

Mapiritsi oyambirira a P1 ndi P2 a thiransifoma yamakono ndi ozungulira ndi mawaya afupikitsa, maulendo onse achiwiri ndi ozungulira pang'ono mpaka pansi, ndipo chishango chomaliza ndi chachifupi chozungulira pansi.(Ngati pamwamba pa thiransifomayo ndi yolemetsa kwambiri, mphete yotchinga iyenera kuikidwa ndikugwirizanitsidwa ndi "G" terminal ya megger ndi waya wotsekedwa.)

Terminal ya "L" ya choyesa chamagetsi champhamvu kwambiri imalumikizidwa ndi materminal P1 ndi P2 a thiransifoma yamakono kapena waya wamfupi, ndipo "E" terminal imakhazikika.

Pambuyo pofufuza mawaya, dinani batani la "Yambani", ndipo mita imayamba kugwira ntchito.Pambuyo pa mphindi ya 1, kukana kwa insulation kudzalembedwa.Mayeso akamaliza, mita iyenera kuchotsedwa ku chitsanzo, kenako dinani batani la "stop" kuti muyambitsenso mita.

Pomaliza, tulutsani gawo loyesa la transformer yamakono.
