- 1. Umuvuduko hamwe nu guhuza
（1 electricity Amashanyarazi y'ibyiciro bitatu (380V)
Guhitamo voltage yatoranijwe: Umuvuduko wa voltage ya thyristor ugomba kuba byibuze inshuro 1.5 yumurimo wakazi (usabwa kuba hejuru ya 600V) kugirango uhangane na voltage yumuriro na overvoltage yigihe gito.
Ibiharuro byubu: Ibice bitatu byumutwaro bigomba gukenerwa kubarwa hashingiwe ku mbaraga zose (nka 48kW), kandi icyifuzo cyateganijwe cyikubye inshuro 1.5 icyerekezo nyacyo (nkumutwaro wa 73A, hitamo 125A-150A thyristor).
Kugenzura impirimbanyi: Uburyo butatu-bubiri uburyo bwo kugenzura bushobora gutera kugabanuka kubintu byingufu nihindagurika ryubu. Zero-crossing trigger cyangwa icyiciro-shift igenzura module igomba gushyirwaho kugirango igabanye kwivanga na gride ya power.
（2 electricity Amashanyarazi y'ibyiciro bibiri (380V)
Guhuza n'imihindagurikire y'amashanyarazi: Amashanyarazi y'ibyiciro bibiri mubyukuri ni icyiciro kimwe 380V, kandi hagomba gutoranywa ibyerekezo bibiri (nka BTB ikurikirana), kandi imbaraga zo guhangana nazo zigomba kuba hejuru ya 600V.
Ihinduka ryubu: Ibyiciro bibiri byicyiciro kirenze ibyiciro bitatu (nka 13,6A kumutwaro wa 5kW), kandi hagomba gutoranywa intera nini ya none (nko hejuru ya 30A).
2. Uburyo bwo gukoresha insinga no gukurura
（1 iring Ibyiciro bitatu:
Menya neza ko module ya thyristor ihujwe murukurikirane kumurongo wanyuma winjiza, kandi umurongo wikimenyetso ugomba kuba mugufi kandi utandukanijwe nindi mirongo kugirango wirinde kwivanga. Niba zeru-crossing triggering (uburyo bukomeye bwa reta ya relay) ikoreshwa, guhuza birashobora kugabanuka ariko amabwiriza yo kugenzura ingufu arasabwa kuba hejuru; kuri feri-shift itera, hagomba kwitonderwa kurinda umuvuduko wa voltage (du / dt), kandi hagomba gushyirwaho inzitizi ya capacitori (nka 0.1μF capacitor + 10Ω résistor).
（2 w Ibyiciro bibiri:
Ibice bibiri bya thyristors bigomba gutandukanya neza hagati ya T1 na T2, kandi ibimenyetso byo kugenzura (G) ibimenyetso bigomba guhuzwa numutwaro. Birasabwa gukoresha imbarutso ya optocoupler kugirango wirinde guhuza nabi.
3. Gushyushya gusohora no kurinda
（1 requirements Ibisabwa kugirango ushushe:
Iyo amashanyarazi arenze 5A, hagomba gushyirwaho icyuma gishyushya, kandi amavuta yubushyuhe agomba gukoreshwa kugirango habeho umubano mwiza. Ubushyuhe bwibishishwa bugomba kugenzurwa munsi ya 120 and, kandi gukonjesha ikirere bigomba gukoreshwa mugihe bibaye ngombwa.
（2 measures Ingamba zo kurinda:
Kurinda birenze urugero: Varistors (nkurukurikirane rwa MYG) ikurura voltage ndende.
Kurinda birenze urugero: fuse-blow fuse ihujwe murukurikirane rwumuzunguruko wa anode, kandi umuyaga wagenwe wikubye inshuro 1.25 ugereranije na thyristor.
Igipimo cyimihindagurikire yumubyigano: ugereranije umuyoboro wa RC ugabanya (nka 0.022μF / 1000V capacitor).
4. Imbaraga nimbaraga
Muri sisitemu y'ibyiciro bitatu, kugenzura ibyiciro birashobora gutuma ibintu bigabanuka, kandi ubushobozi bwindishyi bugomba gushyirwaho kuruhande rwa transformateur.
Sisitemu y'ibyiciro bibiri ikunda guhuza bitewe nuburinganire bwimitwaro, birasabwa rero gufata ingamba zeru zambukiranya cyangwa ingamba zo kugenzura igihe.
5. Ibindi bitekerezo
Icyifuzo cyo guhitamo: shyira imbere ya thyristors (nka marike ya Siemens), ihuza ibikorwa byo gukurura no kurinda no koroshya insinga.
Igenzura ryo gufata neza: buri gihe ukoreshe multimeter kugirango umenye uko imiyoboro ya thyristor imeze kugirango wirinde inzira ngufi cyangwa imiyoboro ifunguye; kubuza ikoreshwa rya megohmmeter kugirango ugerageze.
Niba ushaka kumenya byinshi kubyerekeye ibicuruzwa byacu, nyamunekatwandikire!
