Sida loo saxo guddiga kontoroolka ee foornada soo noqnoqda ee dhexe? Tillaabooyinka ciribtirka oo faahfaahsan

Guddiga xakamaynta foornada soo noqnoqda ee dhexdhexaadka ah waa qayb aad muhiim u ah marka foornada soo noqnoqda ee dhexdhexaadka ah ay shaqeyneyso. Laga soo bilaabo xulashada ilaa alxanka guddiga wareegga, si qaladka iyo baaritaanka gabowga, waa xiriiriye aad muhiim u ah. Waxaa ka mid ah, isticmaaleyaal badan ayaa iska indha tiraya shaqada qaladka ah ee guddiga xakamaynta, mana yaqaaniin sida loo saxo guddiga xakamaynta foornada soo noqnoqda ee dhexdhexaadka ah. Maanta waxaan soo koobay nuxurka laxidhiidha talaabooyinka hagaajinta guddiga xakamaynta si aan kuu sharaxo, aynu si wada jir ah u eegno.

1. Tallaabooyinka wax-ka-qabashada ee qaybta hagaajinta ee guddiga xakamaynta ee foornada soo noqnoqda ee dhexdhexaadka ah

1. Badbaadada qaladka, buundada inverter waa in la naafo ka hor inta aan la tirtirin.

2. Sahay koronto oo saddex weji ah ayaa la bixin karaa, iyadoon loo eegin taxanaha wejiga, oo hubi inay jirto warbixinta digniinta fashilka wejiga. Hadday sidaas tahay, hubi in fiyuuska degdega ah ee imanaya uu dhaawacmay.

3. U rog potentiometer-ka “la siiyey” ee guddida dhinaca saacada weyn, mawjada danabka DC waa in si buuxda loo sii daayo, dhammaan 6da mawjadaha mawjadaha ayaa ku jira. tilmaan wakhtigan Qiyaastii 380V. Ka dib u rog mitirka “la siiyey” potentiometer-ka guddida dhanka ka soo horjeeda oo u leexo mid yar, mawjada korantada DC ayaa ku dhawaad ​​gebi ahaanba xiran, iyo xagasha A waxay ku saabsan tahay 530 digrii wakhtigan. Qaabka mawjada DC ee wax soo saarka waa in uu ahaado mid joogto ah oo siman inta kala duwanaanshaha wareegtada wajiga oo dhan.

4. Xaaladda korontadu xumaato, ku xidh buundada inverter-ka si aad u samaysid inverter kiciya garaaca garaaca wadnaha, oo ka saar culayska iska caabinta ee dekedda buundada toosiye. U rog qalabka wax lagu gooyo ee “W1VF” ee looxa wareegga saacadda saacadda u socota ilaa dhammaadka, (marka kororka korontadu ay dhacdo inta lagu jiro habka cilladaynta, waxay bixin kartaa ilaalinta xad-dhaafka ah). Dareemida guddiga kontoroolka ugu weyn waxaa loo dejiyay booska ON, iyo “la siiyay” potentiometer-ka guddiga wuxuu u wareegayaa saacad ka soo horjeeda.

5. Kadib markaad shid dhowr ilbiriqsi, u rog mitirka “la siiyey” potentiometerka dhinaca saacadda si tartiib tartiib ah si aad u kordhiso. Waqtigan xaadirka ah, buundada inverter waxay ka soo muuqan doontaa laba gobol oo shaqeeya, mid waa buundada inverter-ka, kan kalena waa buundada inverter-ka iyada oo loo marayo. Waxa loo baahan yahay wakhtigan waa isku xirka tooska ah ee buundada inverter. Haddii buundada inverter waa in gobolka oscillating ah, marxaladda Transformer danab inta jeer dhexdhexaadka ah lagu hagaajin karaa in gobolka awood la’aan, in uu yahay, line wax soo saarka ee transformer inta jeer ee dhexdhexaadka ah 20V dabaysha waa la hagaajin karaa. Waxay bilaabi doontaa inay gariirto. Hawlgalka si tartiib tartiib ah u rogaya “potentiometer” ee “la siiyey” ee guddiga weyn, fiiro gaar ah u yeelo jawaabta ammeterka. Haddii calaamadda ammeter-ka ay si degdeg ah u korodho, waa inaad si degdeg ah u leexisaa saacadda “la siiyey” potentiometer-ka. ,

6. Waqtigan xaadirka ah, waxay muujinaysaa in ay jirto dhibaato ka jirta wareegga muunada ee hadda jira, nidaamkuna wuxuu ku yaalaa xaaladda furan ee hadda furan. Hubi in transformerka hadda uu ku xiran yahay iyo in kale. Waxqabadka caadiga ah ayaa ah marka “la siiyay” potentiometer-ka si tartiib ah u kordho, calaamadda ammeter-ka ayaa sidoo kale kordhisa. Marka potentiometer-ka “la siiyey” uu istaago wareegtada, tilmaanta ammeter-ka ayaa si adag u istaagi karta qiyaas cayiman.

7. Marka ay jirto arrin caadi ah, u rog mitirka “la siiyey” potentiometer-ka guddida dhanka saacadda si aad uga dhigto tilmaanta ammeter-ka ku dhawaad ​​50% qiimaha la qiimeeyay. Voltmeter-ka xabagta hadda waxa uu cabbiraa danabka u dhexeeya saddexda terminal. Saddexda danab waa in ay isku qiyaas noqdaan. Haddii kala duwanaanshuhu uu aad u weyn yahay, waxay la macno tahay in terminalka leh magaca isku midka ah ee beddelka hadda uu si khaldan ugu xiran yahay. Waa in la saxo, haddii kale waxay saameyn doontaa shaqada caadiga ah ee maamulaha hadda jira. .

8. Sii wad inaad u leexiso mitirka “la siiyey” ee guddida saacada dhinaceeda ilaa dhamaadka, tilmaanta ammeterku waa inay ku dhowdahay qiimaha la qiimeeyay, oo ku hagaaji wakhtiga xaadirka ah ee guddiga kontoroolka ugu weyn si ka soo horjeeda si aad u quudiso potentiometer-ka gooynta si loo sameeyo DC ammeter waxay tilmaamaysaa soo-saarka la qiimeeyay hadda. Dejinta hadda la qiimeeyay waa la dhammaystiray. Sidan oo kale, ciribtirka buundada hagaajinta ayaa asal ahaan la dhammeeyaa, waxaana la samayn karaa hagaajinta buundada inverter.

9. Marka tamarta korantada ee goobta wax-ka-qabashada aysan bixin karin hadda la qiimeeyay ee qalabka, dejinta hadda la qiimeeyay ayaa la fulin karaa marka goobta ay ku socoto culeys buuxa. Si kastaba ha ahaatee, waa in aad marka hore go’aamiso in wareegga muunada hadda uu si habboon u shaqaynayo iyada oo la eegayo xaaladda hadda yar.

Marka labaad, tillaabooyinka wax-ka-beddelka ee qaybta beddelka ee guddiga xakamaynta ee foornada soo noqnoqda ee dhexdhexaadka ah

1, miiska soo noqnoqda calibration

DIP -2 ee dareemada guddiga kontoroolka ugu weyn ayaa lagu dhejiyaa booska ON, DIP -3 waxaa lagu dhejiyaa booska OFF, iyo “potentiometer” ee “la siiyey” ee guddiga ayaa hoos u dhigaya saacadda. Ku xidh oscilloscope kiis tuubada Q5 ama Q6, cabbir inta jeer ee kale ee xamaasadda garaaca garaaca inverter (inta jeer ee kale ee kicinta lagu hagaajin karaa by FMAX iyo DIP-1), hagaajin: W6 FHZ “si fiican u habayn potentiometer ah si ay u sameeyaan. akhrinta mitirka soo noqnoqda Waxay la socotaa tan lagu cabbiro oscilloscope. Haddii korontadda soo noqnoqoshada dhexdhexaadka ah ay isticmaasho mitir soo noqnoqoshada dhexdhexaadka ah ee gaarka ah, tallaabadan cillad-bixinta waa laga saari karaa.

2, beddelka bilawga

(1) Marka hore, hubi in xariiqda albaabka thyristor inverter ay si sax ah ugu xiran tahay, iyo in iftiinka LED-ka ee marxaladda ugu dambeysa ee beddelka uu yahay mid caadi ah. Haddii aysan dhalaal lahayn, waxay ka dhigan tahay in E iyo C terminal ee marxaladda inverter ay dib u noqdaan; ka dibna guddiga kontoroolka ugu weyn Ka saar xiriirka dibadda ee UA sare, oo arag haddii heerka inverter LED in la demiyo waa in booska geesoodka buundada inverter ah.

(2) U rog DIP-2 ee dareemaha DIP ee guddiga kontoroolka ugu weyn ee booska ON iyo DIP-3 booska OFF, u leexi “potentiometer” “la siiyey” ee guddiga ilaa dhammaadka, oo hagaaji “W5” guddiga xakamaynta. FMAX “Potentiometer Fine-habayn iyo DIP-1, ka dhigi inta jeer excitation sare ka badan 1.4 jeer ee taangiga resonance inta jeer ee wareegga resonance, “W3MAX” iyo “W4MIN” potentimeters ganaax-habayn waxaa loo rogay booska dhexe. U rog mitirka “la siiyey” potentiometer-ka guddida saacada dhinaceeda ilaa xad aad u badan, ka dibna xamaasaddeeda xamaasad waxay bilaabataa inay kor ilaa hoos ka xaaqdo. Buundada rogasha waxay gashaa gobolka shaqada waxayna bilaabataa inay gariirto.

(3) Haddii aysan gariirin, waxaa lagu tusi doonaa sida ay u kiciso calaamadda si ay u qabato ficillada xaaqidda soo noqnoqda, taas oo hagaajin karta marxaladda wareegga korantada ee dhexdhexaadka ah, taas oo ah, dib u celinta xariiqda wax soo saarka ee 20V ee dabaysha Transformer danab inta jeer dhexdhexaad ah. Haddii xariiqda wax soo saarka ee dabaylaha 20V ee beddelka korantada inta jeer ee dhexdhexaadka ah dib loo rogo, wali way ku guul daraysatay inay bilowdo. Waqtigaan, waa inaad xaqiijisaa in inta jeer ee dhawaaqa wareegga taangiga uu sax yahay. Waxaad isticmaali kartaa capacitance/inductance mitir si aad u cabbirto awoodda kuleyliyaha iyo inductance inductor. Xisaabi inta jeer ee resonant ee wareegga haanta. Marka inta jeer ee resonant ee wareegga taangiga uu ku dhex jiro inta u dhaxaysa 0.6 ilaa 0.9 ee soo noqnoqoshada kicinta, waa in si fudud loo bilaabo. Talaabada xigta waa in la hubiyo in thyristor inverter-ka uu dhaawacmay.

3, dhig xagasha hore ee hogaanka danbe

(1) Ka dib markii inverter bilaabo inuu gariiro, waxaad samayn kartaa shaqada dejinta xagasha hore ee inverter ah. Dareemida DIP DIP-2 booska ON iyo DIP-3 booska OFF. Qalabka garaaca wadnaha ayaa eegaya qaabka mawjada 100V ee dabaysha koronto-dhaliyaha wuxuuna hagaajiyaa “W4MIN” potentiometer-ka-habboon ee wanaagsan ee guddiga kontoroolka ugu weyn wuxuu ka dhigayaa xagal-beddelka wareegga wareegga 25 °. Waqtigan xaadirka ah, saamiga korantada soo noqnoqda dhexdhexaadka ah ee dhexdhexaadka ah ee tamarta DC waxay ku dhowdahay 1.3.

(2) U rog DIP-3 beddelka booska ON mar kale, hagaajin “W3 MAX” gooynta potentiometer ee guddiga kontoroolka ugu weyn, oo dhig xagasha hore ee hogaanka wejiga beddelka. Marka loo eego kala duwanaanshaha soo-saarka soo noqnoqda ee dhexdhexaadka ah ee 750V, xagal beddelka gaddoonka ayaa loo baahan yahay inuu ahaado qiyaastii 42°. Waqtigan xaadirka ah, saamiga korantada soo noqnoqda dhexdhexaadka ah ee dhexdhexaadka ah ee tamarta DC waa 1.5.

(3) Haddii ay jirto xagal hore oo aad u weyn oo rogrogis ah inta lagu jiro qaladka, hubi in inta jeer ee resonance wareegga taangiga uu aad u hooseeyo.

4. Dejinta danab wax soo saarka la qiimeeyay

Deji korantada wax soo saarka ee lagu qiimeeyay xaaladaha culeyska fudud, deji DIP beddelka DIP-2 ee guddiga kontoroolka ugu weyn booska ON iyo DIP-3 booska OFF. “Potentiometer-ka u leexi dhanka saac, buundada rogo-rogtadana way shaqeysaa. Sii wad inaad u leexiso mitirka “la siiyey” potentiometerka dhinaca saacada si aad u kordhiso. Waqtigan xaadirka ah, soo-saarka tamarta soo noqnoqda ee dhexdhexaadka ah wuxuu ku dhow yahay qiimaha la qiimeeyay. Hagaaji “W1VF” hagaajinta tayada wanaagsan ee potentiometer-ka gees saacada gees ah si aad uga dhigto soosaarka soo noqnoqda inta jeer ee dhexdhexaadka ah inuu gaaro qiimaha la qiimeeyay.
