Bareki ba ntseng ba eketseha ba botsa hore na phase angle control scr power regulator ke eng?Kajeno re tla u fa selelekela.

Nka tsamaiso ea mekhahlelo e meraro e le mohlala, joalokaha bohle re tseba.Karolong e 'ngoe le e' ngoe, ho na le li-SCR tse peli tse tšoanang.Ka taolo ea phase-angle, SCR e 'ngoe le e' ngoe ea li-back-to-back pair e buletsoe bakeng sa karolo e fapaneng ea halofo ea potoloho eo e e tsamaisang.Matla a laoloa ke ho ntšetsa pele kapa ho lieha ntlha eo SCR e buloang ka eona ka har'a potoloho e 'ngoe le e' ngoe ea halofo.Letšoao la analoge la 4-20mA le khetholla boemo le boholo ba angle shift shift.Ka ho fetola lets'oao la analog, tlhahiso e ka laoloa.

Phase-angle control e fana ka tharollo e ntle haholo ea matla 'me e sebelisetsoa ho laola meroalo e arabelang ka potlako e kang mabone a tungsten-filament kapa meroalo eo ho hanyetsa ho fetohang e le mosebetsi oa mocheso.Khethong ea sehlahisoa e tlameha ho ela hloko, haeba mojaro oa hau o le inductive kapa transformer, joale o tlameha ho sebelisa taolo ea angle angle, mokhoa oa ho tšela zero o tla lebisa leetong la hajoale.

Phase-angle scr power regulatorshangata li theko e boima ho feta balaoli ba zero-cross hobane potoloho ea phase-angle e hloka ho rarahana ho feta potoloho ea zero-cross.E le ho finyella litlhoko tsa bareki kamolaoli oa matla, lihlahisoa tsa taolo ea matla tsa k'hamphani ea rona tseo u ka li behang ho laola karolo kapa taolo ea zero, e bonolo haholo.E ka sebelisoa maemong a fapaneng a mojaro.

Molemo oa taolo ea angle ea mohato ke hore ho nepahala ha taolo ho phahame, 'me tlhahiso ea molaoli oa matla e eketseha butle-butle ho ea ka boleng bo fanoeng ho fihlela boleng bo behiloeng.E ka theha tsamaiso e koetsoeng e nang le letšoao la hona joale, letšoao la motlakase, mocheso oa mocheso, joalo-joalo Ka taolo ea PID, tsamaiso eohle ea taolo e tsitsitse ebile e ka tšeptjoa.

Phase angle control le zero crossing control ke mekhoa e 'meli e fapaneng ea taolo eabalaoli ba matla ba scr, ba na le maemo a bona a fapaneng a ts'ebeliso.Ha ke khone ho bolela feela hore na ke tsela efe e molemo, e ka bolela feela hore lits'ebetso tse fapaneng li hloka taolo e fapaneng.
