IS200EHPAG1ABB GE EXCITER GATE PULSE AMPLFIER BOARD
The is200ehpag1a ke karolo ea letoto la ex2100. Ketso ea amplifier ea pulse ke ho laola ka kotloloho rectifier e laoloang ke silicon (scr).
Lihokelo tsena tsa plug lia fapana khethong ea tsona le palo ea tsona. 8 ea tsona e habeli, 4 ke 4 le 2 ke 6. Sehokelo se teng sekhutlong se kaholimo ho le letona la boto ea potoloho haufi le litepisi tse 'ne mme se ka sebelisoa e le sesebelisoa sa phanele.
Khabinete ea phetolo ea matla e na le mojule oa ho fetolela matla (PCM), boto ea "pulse amplifier" (EGPA), AC circuit breaker le DC contactor. Matla a likarolo tse tharo ho PCM a tsoa ho PPT ka ntle ho exciter. Motlakase oa AC o kena ka har'a khabinete ka sekhechana sa potoloho ea AC (haeba o na le matla) 'me o sefshoa ka filthara ea mekhahlelo e meraro ka har'a khabinete e thusang.
Ho Khaotsoa ha Matla ka Matsoho (Ha ho boikhethelo)
The manual air circuit breaker disconnect switch ke sesebelisoa sa ho hakolla lipakeng tsa motlakase oa phepelo ea motlakase oa bobeli le exciter e tsitsitseng. Ke kesi e bōpiloeng, e nang le mekhahlelo e meraro, e sa iketselitseng, e kentsoeng ka phanele e sebelisoang ka letsoho ho arola matla a ho kenya AC. Ke sesebelisoa sa ho hakolla se se nang mojaro.
Power Conversion module (PCM)
PCM ea exciter e kenyelletsa mochini o lokisang borokho, li-fuse tsa leoto tsa DC, li-circuits tsa ts'ireletso tsa thyristor (mohlala, li-dampers, li-filters, le li-fuse), le likarolo tsa reactor tsa leoto. Ho itšetlehile ka matla a hlokahalang, likarolo li tla fapana bakeng sa litekanyetso tse fapaneng tsa borokho.
Li-Rectifiers tsa Bridge
E 'ngoe le e' ngoe ea borokho bo lokisang borokho ke borokho ba 3-phase full-wave thyristor bridge, joalokaha ho bontšoa ho Setšoantšo sa 2-3, se nang le 6 SCRs (thyristors) e laoloang ke boto ea Excitation Gate Pulse Amplifier (EGPA). Mocheso o felloa ke lisinki tse kholo tsa mocheso oa aluminium le moea o qobelloang ho tsoa ho lifenehi tse holimo.
Li-reactors tsa Leoto le Li-Cell Snubbers
Li-reactors tse tsamaeang li fumaneha maotong a AC a fanang ka li-SCR, 'me li-dampers ke li-circuits tsa RC ho tloha ho anode ho ea ho cathode ea SCR ka' ngoe. Li-cell dampers, line-line dampers, le line reactors li etsa mesebetsi e latelang hammoho ho thibela ts'ebetso e fosahetseng ea SCRs.
- Fokotsa sekhahla sa ho fetoha ha hona joale ka li-SCR le ho fana ka tsela e teng hona joale ho thusa ho qala ho khanna.
- Fokotsa sekhahla sa ho fetoha ha motlakase pakeng tsa lisele le ho fokotsa motlakase o ka morao o hlahang pakeng tsa lisele nakong ea phetoho ea lisele.
Lits'oants'o tsa SCR li kenyelletsa li-resistors tsa PRV ho fokotsa matla a holimo. Li-resistors tsena li ka tlosoa ha ho hlokahala
Matla a ho kenya likarolo tse tharo a feptjoa ho tloha ho bobeli ba PPT ho ea ho borokho bo lokisang borokho, ebang ke ka ho toba kapa ka mochine oa potoloho ea AC kapa ho khaola switch le li-filters tsa line-to-line. Ka moralo o feto-fetohang oa borokho, mochini o lokisang borokho o khona ho sebelisa motlakase o mobe, o fana ka karabelo e potlakileng bakeng sa ho hana mojaro le ho tlosa thabo. Sephetho sa hajoale sa DC sa borokho ba borokho se fepeloa ka shunt mme, ka meralo e meng, ka sehokelo (41A kapa 41A le 41B) lebaleng la jenereithara. Meralo ea ho lokisa borokho e sebelisa li-fuse tsa maoto tsa DC ho sireletsa li-SCR ho tsoa ho overcurrent.
