Igice cyuzuye cya feri igenzurwa arc guhagarika coil
Ibisobanuro by'amahame asobanura
Icyiciro kigenzurwa na arc guhagarika coil nanone bita "ubwoko bwihuse bwumuzunguruko wihuta", ni ukuvuga, guhinduranya kwambere kwingingo yo guhagarika arc mubikoresho byuzuye bihujwe nokutagira aho bibogamiye kumurongo wo gukwirakwiza nkibikorwa bikora, kandi icyiciro cya kabiri kizunguruka gikoreshwa nkigenzura ryahinduwe na bibiri bihujwe na thyristor ni umuzenguruko mugufi, kandi umuyoboro mugufi wumuzunguruko wa kabiri uhindurwa muguhindura inguni ya thyristor, kugirango tumenye ihinduka rishobora kugenzurwa na Agaciro.birashobora guhinduka.
Inguni ya transistor ya thyristor iratandukanye kuva 0 kugeza 1800, kuburyo impedance ihwanye na thyristor itandukana bitagira iherezo kugeza kuri zeru, kandi indishyi zisohoka zishobora guhora zihindurwa nta ntambwe hagati ya zeru nagaciro kagenwe.

Ubushobozi-bushobora guhindurwa arc guhagarika coil yuzuye
Ibisobanuro by'amahame asobanura
Ubushobozi-bwoguhindura arc guhagarika coil ni ukongeramo igiceri cya kabiri mugikoresho cyo guhagarika arc coil coil, kandi amatsinda menshi yimitwaro ya capacitori ihujwe kuburinganire kuri coil ya kabiri, kandi imiterere yayo irerekanwa mumashusho hepfo.N1 ninzitizi nyamukuru, na N2 nicyerekezo cya kabiri.Amatsinda menshi ya capacator hamwe na vacuum ya vacuum cyangwa thyristors ihujwe kuburinganire kuruhande rwa kabiri kugirango ihindure ubushobozi bwa reaction ya capacitori ya kabiri.Ukurikije ihame ryo guhindura impedance, guhindura ubushobozi bwa reaction ya capacitive reaction yinyuma ya kabiri birashobora kuba byujuje ibisabwa kugirango uhindure inductor yumurongo wibanze.Hano hari impushya nyinshi zitandukanye hamwe nubunini bwubunini bwagaciro ka capacitance numubare wamatsinda kugirango uhuze ibisabwa murwego rwo guhinduranya kandi neza.

HYXHX ikurikirana ibikoresho byubwenge arc guhagarika ibikoresho
Mu gihugu cyanjye sisitemu yo gutanga amashanyarazi 3 ~ 35KV, inyinshi murizo zidafite aho zibogamiye.Ukurikije amabwiriza y’igihugu, iyo habaye icyiciro kimwe kibaye, sisitemu yemerewe gukora hamwe namakosa kumasaha 2, bigabanya cyane igiciro cyibikorwa kandi bikazamura ubwizerwe bwa sisitemu yo gutanga amashanyarazi.Ariko, kubera kwiyongera gahoro gahoro ubushobozi bwo gutanga amashanyarazi ya sisitemu, uburyo bwo gutanga amashanyarazi ni Umurongo wo hejuru uhindurwa buhoro buhoro umurongo wa kabili, kandi ubushobozi bwa sisitemu yubutaka buzaba bunini cyane.Iyo sisitemu igizwe nicyiciro kimwe, arc yakozwe numuyoboro mwinshi wa capacitif ntago byoroshye kuzimya, kandi birashoboka cyane ko byahinduka mugihe gito arc ihagarara.Muri iki gihe, arc ihagarara hejuru ya volvoltage hamwe na ferromagnetic resonance overvoltage ishimishijwe nayo izaba Ihungabanya cyane imikorere yumuriro wamashanyarazi.Muri byo, icyiciro kimwe arc-ground overvoltage nicyo gikomeye cyane, kandi urwego rurenze urugero rwicyiciro kitari amakosa rushobora kugera ku nshuro 3 kugeza kuri 3,5 zisanzwe zikoreshwa na voltage isanzwe.Niba amashanyarazi arenze urugero akora kuri gride yamashanyarazi amasaha menshi, byanze bikunze byangiza insulasiyo yibikoresho byamashanyarazi.Nyuma yinshuro nyinshi zangirika ziterwa no kubika ibikoresho byamashanyarazi, hazashyirwaho ingingo idakomeye yo gukumira, ibyo bikaba bizatera impanuka yo gusenyuka kwubutaka hamwe n’umuzunguruko mugufi hagati yibyiciro, kandi icyarimwe bigatera kwangirika kw'ibikoresho by'amashanyarazi (cyane cyane gusenyuka kwa insuline ya moteri)), ibintu byo guturika kwa kabili, kwiyuzuza kwa transformateur ya voltage itera umubiri wa ferromagnetic resonance gutwika, no guturika kwabafata nizindi mpanuka.
