Koyar da ku yadda ake sarrafa injin wutar lantarki

Matsayin farawa na induction narkewa:

Kafin farawa, bincika ko kewayen wutar lantarki yana da kyau, ko abubuwan da aka gyara sun lalace, ko kowane wurin tuntuɓar ya kwance ko kuma an cire haɗin.

Abin mamaki, idan yanayin da ke sama ya faru, ana iya kunna wutar lantarki bayan an kawar da kuskuren.

(1) Kira ma’aikatan tashar da ke bakin aiki don rufe ma’aikatar wutar lantarki ta wutar lantarki, da ƙarfin wutar lantarki, da sanya hannu kan rikodin watsa wutar lantarki;

(2) Sanya safar hannu da rufe maɓallan hannu guda shida a ƙarƙashin majalisar rarraba wutar lantarki, kuma ku lura ko voltmeter mai shigowa akan panel ɗin yayi daidai da ƙarfin samar da wutar lantarki, kuma ana buƙatar ƙarfin lantarki mai shigowa mai hawa uku don daidaitawa;

(3) Fara voltmeter na layin da ke shigowa akan majalisar samar da wutar lantarki don nuna ƙarfin wutar lantarki, hasken mai nuna wutar lantarki (rawaya) yana kunne, kuma hasken siginar inverter (ja) yana kunne, da farko kunna potentiometer na wutar lantarki counterclockwise. zuwa matsayi na sifili (zuwa ƙarshen), kuma danna maɓallin inverter Maɓallin aiki (kore), hasken aikin inverter (kore) yana kunne, kuma mai nuna voltmeter na DC akan kofa ya kamata ya kasance ƙasa da sikelin sifili;

(4) karfin lita. Da farko, daidaita ƙarfin ƙarfin ƙarfin ƙarfin agogo kaɗan kaɗan. A wannan lokacin, kula da kafa tsaka-tsakin mitar kuma ku ji sautin busawa, wanda ke nuna cewa an fara samar da wutar lantarki ta tsaka-tsakin cikin nasara. Sa’an nan ne kawai za a iya barin potentiometer wutar lantarki ya juya sannu a hankali a kan agogo, kuma kada ya janye shi da sauri. Ƙarfin, ƙara ƙarfin a hankali, idan har yanzu ba a kafa mitar IF ba, juya potentiometer baya kuma sake farawa;

(5) Lokacin da aka kunna wutar, idan babu sauti ko maras kyau a mitar mitar, to kada a tilasta masa ya fara, sai a sake ja da ma’aunin wutar lantarki a karkashi zuwa karshen, sannan a sake kunnawa. Idan sau da yawa ba su yi nasara ba, ya kamata a rufe a duba;

(6) A matakin farko na loading (lokacin da ake ci gaba da ɗorawa ƙarfe ingots), ƙarfin ya kamata a daidaita shi zuwa 2000kW, don haka ƙarfin daidaitawar wutar lantarki ya kamata ya kasance da gefe (ba dole ba ne a daidaita ma’aunin ƙarfin zuwa cikakke) don hana haɓakar kwatsam iko da halin yanzu saboda aikin lodawa High, yana haifar da lalacewa ga thyristor. Bayan an kammala lodi, sannu a hankali ƙara ƙarfin zuwa fiye da 3000kW;

(7) A tsakiyar da kuma ƙarshen matakai na narkewa, ya kamata a rage ikon zuwa 2000kW (rage ƙarfin). Bayan an cika cika, sannu a hankali daidaita wutar lantarki zuwa fiye da 3000kW don hana haɓakar wutar lantarki da na yanzu yayin aikin caji. Lalacewar tasirin thyristor;

(8) Idan akwai haɓaka kayan aiki a cikin tanderun, kar a daidaita ƙarfin ƙarfin wutar lantarki a wannan lokacin, kuma kar a yi aiki da ƙarfi mai ƙarfi. Ya kamata a sarrafa wutar lantarki a 2000kW don hana ƙwayar karfe daga fadowa cikin tanderun ba zato ba tsammani, haifar da karuwa da sauri a cikin wutar lantarki da halin yanzu. , Yana haifar da lalacewar tasiri ga thyristor;

(9) A lokacin aikin narkewar, idan tsarin ya yi tafiya ba zato ba tsammani, ya kamata ku gano musabbabin tafiya a hankali, kuma a hankali bincika wutar lantarki da tsarin wutar lantarki na tsaka-tsaki don yatso, matsa lamba na al’ada, da alamun kunnawa. Kar a sake kunna wutar lantarki ta tsaka-tsaki a makance. , Don hana haɓakar kuskuren, haifar da lalacewa ga tsarin wutar lantarki, thyristor da babban jirgi;

(10) Alakar al’ada tsakanin halin yanzu da ƙarfin lantarki lokacin da aka daidaita wutar zuwa cikakken ƙarfin ƙarfin wutar lantarki shine:

IF ƙarfin lantarki = DC ƙarfin lantarki x 1.3

Wutar lantarki ta DC = ƙarfin lantarki mai shigowa x 1.3

DC halin yanzu = layin mai shigowa na yanzu x 1.2

(11) Bayan tabbatar da cewa komai na al’ada ne bayan rufewa, rataya alamar ( watsa wutar lantarki) akan birki na hannu.

Matsakaicin rufe wutar lantarki na narkewa

(1) Da farko juya ikon potentiometer counterclockwise zuwa karshen. Lokacin da DC ammeter, DC voltmeter, mitar mita, matsakaici mitar voltmeter, da kuma wutar lantarki a kan inverter ikon majalisar sun zama sifili, danna maɓallin tasha inverter (ja), Hasken inverter tasha (ja) yana kunne.

(2) Zazzage maɓallan hannu guda shida a ƙasan ɓangaren majalisar rarraba wutar lantarki, sannan ka rataya alamar ( gazawar wutar lantarki).

(3) Sanar da ma’aikatan tashar da ke bakin aiki don cire haɗin na’urar sauya sheka da yanke wutar tanderun narkewa.

(4) Yayin aiki na wutar lantarki na inverter, kayan aikin lantarki ya kamata a rubuta su kuma a kula da su kamar yadda ake bukata. Idan an sami wasu abubuwa marasa kyau, yakamata a rufe injin kuma a bincika dalilin da ya faru nan da nan, kuma ana iya ci gaba da aikin bayan an kawar da laifin.

(5) A lokacin da injin inverter ke aiki, idan aka sami yabo ko toshe ruwa a cikin hanyar ruwa da abubuwan sanyaya ruwa, sai a rufe injin a duba a yi maganinta. Bayan gyarawa da bushewa tare da na’urar bushewa, ana iya kunna shi kuma a sake amfani dashi.

(6) A lokacin aiki na inverter samar da wutar lantarki, an haramta sosai don gudanar da lura karkatarwa, karkatar da tapping, da ciyar da ayyuka tare da wuta a kunne. Dole ne a yi ayyukan da ke sama bayan dakatar da samar da wutar lantarki.
