IS200EHPAG1ABB GE EXCITER GATE PULSE AMPLFIER BOARD
I-is200ehpag1a iyingxenye yochungechunge lwe-ex2100. Isenzo se-pulse amplifier ukulawula ngokuqondile i-silicon controlled rectifier (scr).
Lezi zixhumi zepulaki ziyahlukahluka ekukhethweni kwazo kanye nenombolo. Ezingu-8 zazo ziphindwe kabili, ezi-4 ziyi-4 kanye nezi-2 ziyi-6. Isixhumi sitholakala ekhoneni eliphezulu kwesokudla sebhodi lesifunda eduze kwezitendi ezine futhi singasetshenziswa njengesesekeli sephaneli.
Ikhabethe lokuguqula amandla liqukethe imojula yokuguqula amandla (i-PCM), ibhodi le-excitation gate pulse amplifier (EGPA), i-AC circuit breaker kanye ne-DC contactor. Ukunikezwa kwamandla kwezigaba ezintathu ku-PCM kuvela ku-PPT ngaphandle kwe-exciter. Amandla e-AC angena kukhabhinethi nge-AC circuit breaker (uma inikwe amandla) futhi ahlungwa yisihlungi somugqa wezigaba ezintathu kukhabhinethi elisizayo.
Nqamula Amandla Mathupha (Ongakukhetha)
Iswishi yokunqamula i-air circuit breaker iyithuluzi lokunqamula phakathi kwe-supply voltage transformer yesibili kanye ne-static exciter. Ikesi elibunjiwe, elinezigaba ezintathu, okungelona okuzenzakalelayo, iswishi efakwe iphaneli esetshenziswa mathupha ukuhlukanisa amandla okufaka we-AC. Idivayisi yokunqamula engalayishi.
I-Power Conversion Module (PCM)
I-PCM ye-exciter ihlanganisa isilungisi sebhuloho, amafuse emilenze ye-DC, amasekhethi okuvikela i-thyristor (isb., ama-dampers, izihlungi, namafuse), kanye nezingxenye ze-reactor yomlenze. Kuye ngokukhipha amandla adingekayo, izingxenye zizohluka ngezilinganiso ezihlukene zebhuloho.
I-Bridge Rectifiers
Isilungisi sebhuloho ngasinye siyibhuloho le-thyristor lezigaba ezi-3 ezigcwele, njengoba kuboniswe kuMfanekiso 2-3, ohlanganisa ama-SCRs angu-6 (thyristors) alawulwa ibhodi le-Excitation Gate Pulse Amplifier (EGPA). Ukushisa kukhishwa osinki abakhulu bokushisa be-aluminium kanye nokugeleza komoya okuphoqelekile okuvela kumafeni angaphezulu.
I-Leg Reactors kanye Nezinciphisi Zeseli
Ama-reactors ahambayo atholakala emilenzeni ye-AC ehlinzeka ngama-SCR, futhi ama-dampers angamasekhethi e-RC ukusuka ku-anode kuya ku-cathode ye-SCR ngayinye. Ama-dampers amaseli, ama-dampers e-line-to-line, nama-reactors alayini enza imisebenzi elandelayo ndawonye ukuze avimbele ukusebenza okuyiphutha kwama-SCR.
-Nciphisa izinga lokushintsha kwamandla ngama-SCR futhi unikeze irempu yamanje ukusiza ukuqalisa ukuqhuba.
-Khawulela izinga lokushintsha kwamandla kagesi phakathi kwamaseli futhi ukhawule i-voltage ehlehlayo eyenzeka phakathi kwamaseli ngesikhathi sokushintsha kweseli.
Izibambi ze-SCR zifaka i-PRV resistors ukukhawulela i-peak reverse voltage. Lezi resistors zingasuswa uma kunesidingo
Amandla okufaka ezigaba ezintathu anikezwa kusukela kwesibili kwe-PPT kuya kusilungisi sebhuloho, ngokuqondile noma nge-AC circuit breaker noma nqamula iswishi kanye nezihlungi zomugqa ukuya kumugqa. Ngedizayini yokulungisa ibhuloho eguqukayo, isilungisi sebhuloho siyakwazi ukusebenzisa amandla kagesi anegethivu, sinikeze impendulo esheshayo yokwenqatshwa komthwalo kanye nokususa isasasa. Okukhiphayo kwamanje kwe-DC kwesilungisisi sebhuloho kunikezwa nge-shunt futhi, kwamanye amadizayini, ngesixhumi sokuxhumana (41A noma 41A kanye no-41B) kunkambu yokukhiqiza. Amadizayini okulungisa ibhuloho asebenzisa amafuse emilenze ye-DC ukuze avikele ama-SCR ekudluleleni.
