Likopano tse ling tsa Matla
Likopano tse ling tsa Matla
Thepa e laolang matla e etselitsoeng le ho etsoa ka likarolo tsa motlakase oa motlakase ka melemo ea khetho e bonolo, ts'epo e phahameng, litšenyehelo tse tlase tse felletseng, ho kenya habonolo, ponahalo e ntle, lebelo la nts'etsopele e potlakileng, joalo-joalo.
Likopano tsa matla tse entsoeng ka thyristor le diode tse fumanehang hore li ka fanoa:
• Letoto la borokho bo lokisang mohato o le mong: ho kenyelletsa taolo e felletseng ea karolo e le 'ngoe, taolo ea halofo, le borokho bo lokisang
• Letoto la borokho bo felletseng ba mekhahlelo e meraro: ho kenyelletsa tokiso ea taolo e felletseng ea mekhahlelo e meraro, tokiso ea taolo ea karolo e meraro, le borokho ba tokiso ea mekhahlelo e meraro.
• Mehato e ts'eletseng ea borokho ba borokho: ho kenyeletsoa borokho bo laolehang ba mekhahlelo e tšeletseng le bo sa laoleheng.
• AC switjha letoto la lihlooho tse: ho akarelletsa le karolo e le 'ngoe le mekhahlelo e meraro AC switjha
Bakeng sa lipotso tse ling tsa ho kopanya motlakase ka thyristor, diode le rectifier bakeng sa ho lokisa, ho fetola, ho fetola matla le ho laola, ka kopo ikopanye le rona, sehlopha sa tšehetso sa bareki se nang le talenta le litsebi tse nang le phihlelo li ntse li sebetsa.
• Mekhoa e pholileng ea likopano ke pholileng ea moea, pholileng ea tlhaho, le ho pholile ha metsi ka profil ea aluminium le pipe ea mocheso.
• Likarolo tsa likopano ke yuniti ea matla, RC absorption capacitor, tšireletso ea mocheso, likarolo tse akaretsang kapa tse khethehileng tsa ts'ebetso ea taolo.

- Phase e meraro ea anti-parallel power unit e entsoe ke li-SCR tse peli tse hokahaneng ka mokhoa o khahlanong le parallel mokhahlelong ka mong ho hlokomela taolo ea motlakase e laoloang ke AC.E 'ngoe le e' ngoe ea thyristor e sebetsa bakeng sa potoloho ea halofo e ntle le e mpe.Kahoo ho lumellana ha litekanyetso tsa SCR tse peli tse khahlanong le li-parallel tse amanang le SCR li bohlokoa haholo hammoho le litšoaneleho tsa heke le ho tšoara mekhahlelo ea hona joale, joalo-joalo Ho lumellana ha thyristors ho sebelisitsoeng ho tla fana ka maqhubu a halofo e ntle le e mpe e be symmetrical, ho seng joalo hona joale le DC. karolo e tla phalla ka har'a inductive featured motor, motor stator e tla futhumatsoa haholo, ebe li-motor windings li tla chesoa 'me koloi e tla senyeha qetellong.
- Runau e ka fana ka boemo bo phahameng ba boemo bo laoloang ba thyristor le yuniti e amanang le 3 phase anti-parallel power voltage e mahareng ea 1200V/3300V empa hape le matla a phahameng a 4500V/6500V.
- Ho hlokomela ho qala ha bonolo le ho sireletsa li-motor tsa 6kV le 10kV tse phahameng, hoa hlokahala ho hokahanya li-SCR ka anti-parallel ebe o li hokahanya ka letoto ho phethahatsa tlhoko ea ts'ebetso e phahameng ea motlakase.Mokhahlelo o mong le o mong oa 6kV o hloka 6 thyristors (2 ho anti-parallel le lihlopha tse 3 ka letoto), 'me mohato ka mong oa 10kV o hloka li-thyristors tse 10 (2 ka anti-parallel, lihlopha tse 5 ka lihlopha).Ka tsela ena, motlakase o mamelletsoeng oa thyristor e 'ngoe le e' ngoe e ka bang 2000V, kahoo ho ea pele le ho khutlela morao ho sa phete-pheta litekanyetso tsa VDSM le VRSM ea thyristor e khethiloeng e lokela ho ba 6500V kapa ka holimo.Ho khetha tekanyo e lekantsoeng ea thyristor, motlakase o sebetsang oa motlakase o tlameha ho nkoa.Ka kakaretso, nako e khethiloeng ea thyristor e lokela ho ba makhetlo a 3 ho isa ho a 4 a motlakase o lekantsoeng hona joale.
