Yadda za a debug Control Panel na tsaka -tsakin mitar wuta? Cikakken matakan gyara kurakurai

Kwamitin kula da wutar lantarki na tsaka-tsaki yana da mahimmancin mahimmanci lokacin da wutar lantarki ke aiki. Daga zaɓi zuwa waldawar allon da’ira, zuwa gyara kuskure da gwajin tsufa, hanya ce mai mahimmanci. Daga cikin su, masu amfani da yawa za su yi watsi da aikin gyaran gyare-gyare na hukumar kulawa, kuma ba su san yadda za a gyara allon kula da wutar lantarki na tsaka-tsakin ba. A yau na taƙaita abubuwan da suka dace na matakan gyara matakan sarrafawa don bayyana muku, bari mu dube shi tare.

1. Matakan gyaran gyare-gyare na sashin gyarawa na kula da wutar lantarki na matsakaici

1. Don aminci na debugging, da inverter gada ya kamata a kashe kafin debugging.

2. Za a iya samar da wutar lantarki ta matakai uku, ba tare da la’akari da tsarin lokaci ba, kuma a duba ko akwai rahoton gazawar ƙararrawa. Idan haka ne, duba ko fius mai sauri mai shigowa ya lalace.

3. Juya da “ba” potentiometer a kan panel zuwa babban agogon agogon, da DC ƙarfin lantarki waveform ya kamata a kusan a saki, kuma duk 6 taguwar ruwa shugabannin ne a cikin. nuni a wannan lokacin Around 380V. Sa’an nan juya potentiometer “ba” a kan panel counterclockwise zuwa karami, DC ƙarfin lantarki waveform ya kusan rufe gaba daya, kuma kwana A yana kusan 530 digiri a wannan lokaci. Fitar da waveform na DC ya kamata ya kasance mai ci gaba da santsi a cikin kewayon motsi lokaci.

4. A cikin gazawar wutar lantarki, haɗa gadar inverter don yin shigar da inverter jawo bugun bugun jini, kuma cire nauyin juriya a tashar tashar gada mai gyara. Juya na’urar trimming “W1VF” a kan allon kewayawa agogon hannu zuwa karshen, (lokacin da overvoltage na inverter ya faru yayin aiwatar da cirewa, zai iya ba da kariya daga overvoltage). An saita maɓalli a kan babban kwamiti na sarrafawa zuwa matsayin ON, kuma ana jujjuya ma’aunin ƙarfin “da aka ba” akan panel ɗin a kan agogo.

5. Bayan kunna wuta na ƴan daƙiƙa, kunna potentiometer “da aka ba” akan allon agogo a hankali don ƙarawa. A wannan lokacin, gadar inverter za ta bayyana a cikin jihohi biyu masu aiki, ɗaya shine gadar inverter yana oscillating, ɗayan kuma ita ce gadar inverter ta. Abin da ake buƙata a wannan lokacin shine haɗin kai tsaye ga inverter. Idan inverter gada yana cikin yanayin oscillating, za’a iya daidaita lokaci na matsakaicin mitar wutar lantarki a yanayin rashin ƙarfi, wato, layin fitarwa na matsakaicin mitar wutar lantarki na 20V na iska. Zai fara girgiza. A cikin aiki na sannu a hankali juya potentiometer “ba” a kan babban panel, kula da hankali ga amsawar ammeter. Idan alamar ammeter ya karu da sauri, ya kamata ku yi sauri jujjuya ma’aunin ƙarfin ikon “da aka bayar”. ,

6. A wannan lokacin, yana nuna cewa akwai matsala tare da da’irar samfur na yanzu, kuma tsarin yana cikin yanayin madauki na yanzu. Bincika ko an haɗa taransfoma na yanzu. Ayyukan al’ada shine yayin da potentiometer “da aka ba” a hankali yana ƙaruwa, alamar ammeter kuma yana ƙaruwa. Lokacin da “aka ba” potentiometer ya daina juyawa, alamar ammeter na iya tsayawa tsaye a wani ma’auni.

7. Lokacin da akwai wani abu ta hanyar al’amari, juya “ba” potentiometer a kan panel agogon hannu don yin nunin ammeter kusa da kusan 50% na ƙimar ƙima. Manne voltmeter na yanzu yana auna ƙarfin lantarki tsakanin tashoshi uku. Wutar lantarki guda uku yakamata su kasance kusan iri ɗaya. Idan bambamcin ya yi girma, yana nufin cewa an haɗa tasha mai suna iri ɗaya na taswirar yanzu ba daidai ba. Dole ne a gyara shi, in ba haka ba zai shafi aiki na yau da kullum na mai gudanarwa na yanzu. .

8. Ci gaba da kunna potentiometer “da aka ba” akan panel agogon agogo zuwa ƙarshen, alamar ammeter ya kamata ya kasance kusa da ƙimar da aka ƙididdigewa, kuma daidaita halin yanzu akan babban allon kula da agogon agogo don ciyar da potentiometer trimming don yin DC ammeter yana nuna ƙimar fitarwa na halin yanzu. An kammala saitin ƙimar halin yanzu. Ta wannan hanyar, an kammala aikin gyara gada mai gyara, kuma ana iya aiwatar da gyaran gadar inverter.

9. Lokacin da wutar lantarki na wurin cirewa ba zai iya samar da ƙimar halin yanzu na na’urar ba, za’a iya aiwatar da saiti na halin yanzu lokacin da shafin ke gudana a cikakke kaya. Koyaya, yakamata ku fara tantance ko madaukin samfur na yanzu yana aiki da kyau ƙarƙashin yanayin ƙaramin halin yanzu.

Na biyu, matakan gyara na ɓangaren inverter na sashin kula da wutar lantarki na matsakaici

1, tebur mitar daidaitawa

DIP -2 na sauyawa a kan babban kwamiti na sarrafawa an saita shi zuwa matsayi na ON, DIP -3 an saita zuwa matsayi na KASHE, kuma “an ba” potentiometer a kan panel yana jujjuya a gefen agogo. Haɗa oscilloscope zuwa bututun Q5 ko Q6, auna sauran mitar motsawar bugun jini na inverter (sauran mitar tashin hankali za’a iya daidaita shi ta FMAX da DIP-1), daidaita: W6 FHZ “kyau-tune da potentiometer don yin. karatun mitar mita Ya yi daidai da wanda aka auna ta oscilloscope. Idan matsakaicin mitar wutar lantarki yana amfani da mitar mitar mitar ta musamman, za a iya tsallake wannan matakin na cirewa.

2, fara inverter

(1) Da fari dai, duba ko ƙofar line na inverter thyristor an haɗa daidai, kuma ko haske na LED a kan mataki na karshe na inverter ne na al’ada. Idan ba haske ba, yana nufin cewa E da C tashoshi na matakan inverter suna juyawa; sannan babban allon sarrafawa Cire haɗin waje na UA na sama, kuma duba idan matakin inverter LED wanda ke kashe yana cikin matsayi na diagonal na gadar inverter.

(2) Kunna DIP-2 na maɓallin DIP a kan babban kwamiti na sarrafawa zuwa matsayi na ON da DIP-3 zuwa matsayi na KASHE, kunna “ba” potentiometer akan panel zuwa karshen, kuma daidaita “W5” akan. da kula da panel. FMAX “Fine-tuning potentiometer da DIP-1, sa tashin hankali mita mafi girma fiye da 1.4 sau na tanki resonance mita, “W3MAX” da “W4MIN” lafiya-tuning potentimeters suna juya a tsakiyar matsayi. Juya ma’aunin ƙarfi na “ba” akan panel agogon hannu zuwa adadi mai yawa, sa’an nan kuma mitar ta ta fara sharewa daga sama zuwa ƙasa. Gadar inverter ta shiga yanayin aiki kuma ta fara girgiza.

(3) Idan bai yi rawar jiki ba, za a nuna shi yayin da yake motsa siginar don aiwatar da ayyukan share mitoci akai-akai, wanda zai iya daidaita yanayin matsakaicin mitar wutar lantarki, wato juyawa layin fitarwa na iskar 20V na iska. matsakaicin mitar wutar lantarki. Idan layin fitarwa na iskar 20V na matsakaicin mitar wutar lantarki ta sauya sheka, har yanzu ya kasa farawa. A wannan lokacin, ya kamata ka tabbatar ko mitar resonance na da’irar tanki daidai ne. Kuna iya amfani da na’urar iya aiki / inductance mita don auna ƙarfin ƙarfin wutar lantarki da inductance na inductor. Yi ƙididdige yawan resonant na da’irar tanki. Lokacin da resonant mita na da’irar tanki ne a cikin kewayon 0.6 zuwa 0.9 na tashin hankali mita, ya zama da sauki a fara. Mataki na gaba shine bincika ko inverter thyristor ya lalace.

3, saita kusurwar gaba na jagorar baya

(1) Bayan inverter fara rawar jiki, za ka iya yin aikin kafa gaban kwana na inverter. Kunna maɓallin DIP DIP-2 a cikin ON matsayi da DIP-3 a cikin KASHE. Pulser yana lura da yanayin motsi na 100V mai jujjuyawar wutar lantarki kuma yana daidaita Potentiometer mai kyau na “W4MIN” akan babban allon sarrafawa yana sa kusurwar jujjuyawar juzu’i ta juzu’i a kusa da 25 °. A wannan lokacin, rabon matsakaicin matsakaicin ƙarfin fitarwa zuwa ƙarfin DC yana kusa da 1.3.

(2) Juya DIP-3 canza zuwa ON matsayi sake, daidaita da “W3 MAX” trimming potentiometer a kan babban iko kwamitin, da kuma saita gaban kwana na baya hira lokaci gubar. Dangane da nau’in ƙarfin fitarwa na matsakaicin matsakaici na 750V, ana buƙatar kusurwar jagorar juzu’i ta zama kusan 42°. A wannan lokacin, rabon matsakaicin matsakaicin ƙarfin fitarwa zuwa ƙarfin DC shine 1.5.

(3) Idan akwai babban kusurwar gaba na inverter yayin gyarawa, duba ko mitar resonance na tanki ya yi ƙasa sosai.

4. Saitin ƙarfin fitarwa mai ƙima

Saita ƙimar fitarwa mai ƙima a ƙarƙashin yanayin nauyi mai haske, saita maɓallin DIP DIP-2 akan babban allon sarrafawa zuwa matsayin ON da DIP-3 zuwa matsayin KASHE. “Juya madaidaicin mita zuwa agogo, kuma gadar inverter tana aiki. Ci gaba da juya potentiometer “da aka bayar” akan panel agogon hannu don ƙarawa. A wannan lokacin, matsakaicin mitar ƙarfin fitarwa yana kusa da ƙimar ƙima. Daidaita “W1VF” mai kyau-daidaita potentiometer counterclockwise don sa matsakaicin ƙarfin wutar lantarki na fitarwa ya kai ga ƙima.
