Sauran Majalisun Wuta
Kayan aikin sarrafa wutar lantarki da aka tsara da kuma ƙera su tare da kayan aikin lantarki tare da fa'idodin zaɓi mai sauƙi, babban abin dogaro, ƙarancin farashi mai sauƙi, sauƙi mai sauƙi, bayyanar da kyau, saurin haɓaka sauri, da sauransu.
Tarurukan wutar lantarki da aka yi daga thyristor da diode waɗanda ake da su don samarwa:
• Jerin gada mai gyara lokaci-ɗaya: gami da cikakken iko lokaci-ɗaya, sarrafa rabin, da gada mai gyara.
• Jerin cikakken gada mai hawa uku: gami da gyaran fuska mai cikakken iko mai kashi uku, gyaran sarrafa rabin kashi uku, da gadar gyara kashi uku.
• Jerin gada mai gyara-lokaci shida: gami da gadoji masu daidaitawa da ba za a iya sarrafa su ba.
• Jerin sauya AC: gami da na'urar sauya sheka guda-guda da na AC mai hawa uku
Don ƙarin tambayoyin ikon iko da aka yi da tausayinka, diode da mai juyawa don gyara, mai juyawa da sarrafawa, ƙungiyar masu taimako da ƙwarewa da fasaha ke ƙarƙashin bautar.
• Hanyoyin kwantar da hankali na majalisai suna sanyaya iska, sanyaya yanayi, da sanyaya ruwa tare da bayanan aluminum da bututu mai zafi.
• Abubuwan da aka haɗa na taro sune naúrar wuta, RC absorption capacitor, kariyar zafin jiki, gabaɗaya ko kayan aikin sarrafawa na musamman.

- Naúrar wutar lantarki mai kayyade mataki uku ta ƙunshi SCR guda biyu da aka haɗa a cikin yanayin anti-parallel akan kowane lokaci don gane ka'idojin ƙarfin wutar lantarki na lokaci na AC.Kowane thyristor yana aiki don daidaitaccen zagaye na rabi mai kyau da mara kyau.Don haka daidaiton ma'auni na SCR guda biyu anti-parallel da aka haɗa yana da mahimmanci sosai da halayen kofa da kuma riƙe sigogi na yanzu, da dai sauransu A daidaito na thyristors aiki zai samar da tabbatacce da korau rabin raƙuman ruwa zama m, in ba haka ba na yanzu tare da DC. bangaren zai gudana ta cikin injin da aka nuna, za'a yi zafi sosai da injin stator, sannan za'a kona iskar motar kuma motar zata lalace a karshe.
- Runau na iya samar da babban daidaito lokaci sarrafa thyristor da alaka 3 lokaci anti-parallel ikon naúrar a matsakaici irin ƙarfin lantarki na 1200V/3300V amma kuma high ƙarfin lantarki na 4500V/6500V.
- Don gane da taushi farawa da kuma kare 6kV da 10kV high irin ƙarfin lantarki Motors, shi wajibi ne don haɗa SCRs a anti-parallel sa'an nan kuma haɗa su a cikin jerin don cika high ƙarfin lantarki aiki da ake bukata.Kowane lokaci na 6kV yana buƙatar 6 thyristors (2 a cikin anti-parallel da 3 rukunoni a jere), kuma kowane lokaci na 10kV yana buƙatar 10 thyristors (2 a anti-parallel, 5 rukuni a jere).Ta wannan hanyar, ƙarfin lantarki da ke jure wa kowane thyristor yana da kusan 2000V, don haka gaba da jujjuya ƙarfin ƙarfin da ba a maimaita ba VDSM da VRSM na zaɓaɓɓen thyristor yakamata ya zama 6500V ko sama.Don zaɓar halin yanzu na thyristor, dole ne a yi la'akari da ƙimar aiki na yanzu na injin.Gabaɗaya, zaɓin halin yanzu na thyristor yakamata ya zama sau 3 zuwa 4 na injin da aka ƙididdige halin yanzu.
