Ibhokisi lokumelana ne-Damping
Ukuze kuvinjwe i-voltage engalingani yephoyinti elingathathi hlangothi lesistimu yegridi ukuthi ingakhuli ngenxa yokokufaka nesilinganiso sekhoyili yokucindezela i-arc lapho ikhoyili yokucindezela i-arc yemodi yesinxephezelo yokulungisa kusengaphambili isebenza ngaphansi kwesimo esivamile segridi yamandla. , iyacwaningwa futhi iklanywe.Uma igridi yamandla isebenza ngokujwayelekile, lungisa i-inductance yekhoyili yokucindezela i-arc endaweni efanele kusengaphambili, kodwa ngalesi sikhathi i-inductance ne-capacitive reactance cishe ilingana, okuzokwenza igridi yamandla ibe sesimweni esiseduze ne-resonance, okubangela i-voltage yephoyinti engathathi hlangothi izokhuphuka.Ukuze uvimbele lokhu Uma kwenzeka kwenzeka, idivayisi ye-resistor encibilikayo yengezwa kudivayisi yesinxephezelo sekhoyili ye-arc kumodi yokulungiswa kwangaphambili, ukuze kucindezelwe i-voltage yokugudluka yephoyinti elingathathi hlangothi iye endaweni efanele edingekayo futhi kuqinisekiswe okuvamile. ukusebenza kwenethiwekhi yokuphakela amandla.

Isethi ephelele yekhoyili yokucindezela i-arc elawulwa ngesigaba
Incazelo yesimiso sesakhiwo
Ikhoyili yokucindezela i-arc elawulwa yisigaba nayo ibizwa ngokuthi “uhlobo lwe-high short-circuit impedance”, okungukuthi, ukusonga okuyinhloko kwekhoyili yokucindezela i-arc kudivayisi ephelele ixhunywe endaweni engathathi hlangothi yenethiwekhi yokusabalalisa njengomoya osebenzayo, futhi ukusonga kwesibili kusetshenziswa njengokulawula ukusonga okubili okuxhumeke ngokubuyela emuva I-thyristor ine-circuited short-circuited, kanti i-short-circuit current kuma-winding esibili ilungiswa ngokulungisa i-conduction angle ye-thyristor, ukuze kubonakale ukulungiswa okulawulwayo inani lokusabela.iyalungiseka.
I-engeli conduction ye-thyristor iyahlukahluka ukusuka ku-0 kuye ku-1800, ukuze i-impedance efanayo ye-thyristor ihluke ukusuka kokungapheli kuye ku-zero, futhi isinxephezelo samanje esiphumayo singalungiswa ngokuqhubekayo ngaphandle kwesinyathelo phakathi kweziro kanye nenani elilinganiselwe.

Isethi ephelele yekhoyili yokucindezela i-arc ekwazi ukushintsha amandla
Incazelo yesimiso sesakhiwo
Ikhoyili yokucindezela i-arc eshintsha amandla iwukwengeza ikhoyili yesibili kudivayisi yekhoyili yokucindezela i-arc, futhi amaqembu amaningana emithwalo ye-capacitor axhunywe ngokuhambisana kukhoyili yesibili, futhi ukwakheka kwayo kuboniswe esithombeni esingezansi.I-N1 iwukujikajika okukhulu, kanti i-N2 iwukujika kwesibili.Amaqembu amaningana ama-capacitor anama-vacuum switch noma ama-thyristors axhunywe ngokuhambisana ohlangothini lwesibili ukuze alungise ukusabela kwe-capacitive ye-secondary side capacitor.Ngokomgomo wokuguqulwa kwe-impedance, ukulungisa inani le-capacitive reactance yohlangothi lwesibili kungahlangabezana nemfuneko yokushintsha i-inductor yamanje yohlangothi oluyinhloko.Kunezimvume eziningi ezihlukene nezinhlanganisela zosayizi wevelu ye-capacitance kanye nenani lamaqembu ukuhlangabezana nezidingo zobubanzi bokulungisa nokunemba.
