2. Uhlelo lwesekethe oluyinhloko
Uhlelo oluyinhloko lwesekhethi lwedivayisi lunamaqembu angu-32 kanye nemininingwane engu-118, ngaphandle kwezinhlelo kanye nemininingwane etholakala ekushintsheni kokulawula nokuvikela isekethe eyisizayo. Luhlanganisa izidingo zokukhiqizwa kwamandla, ukunikezwa kwamandla kanye nabanye abasebenzisi bamandla. Umthamo wamandla osebenzayo olinganiselwe ngu-4000A, ofanele ukukhethwa kwama-transformer okusabalalisa angaphansi kuka-2500kVA. Ngaphezu kwalokho, ikhabhinethi yesinxephezelo se-capacitor yenzelwe ukuhlangabezana nezidingo zokuhlinzekwa kwamandla kanye nokuthuthukiswa kwamandla. Uma kucatshangelwa isidingo sokutshalwa kwezimali okuphelele, ikhabhinethi ye-reactor yaklanywa.
Amazwi:
①I-DW914 iyi-circuit breaker eyinhloko, kanti nezinye izi-circuit breaker ezinokusebenza okuthuthukile noma uchungechunge lwe-RDSW6 (RDW1), FM nazo zingakhethwa.
Izixazululo ze-②01, 02, 04 uma ikhebula le-PE N lidinga ukungena kwikhabhinethi yamandla, ububanzi bekhabhinethi kufanele bulinganiswe ngamabakaki.
③I-SDL kanye ne-SDH ziyiziguquli zamandla ezikhethekile zamakhabethe e-GCS.
3. Uhlelo lwesekethe olusizayo
Kunezinhlelo zesekethe ezisizayo eziyi-120 ku-GCS Auxiliary Circuit Atas, ezihlukaniswe ngamavolumu amabili. Umqulu wokuqala "Ingxenye Yokusebenza ye-AC" uhlukaniswe ngama-scheme angu-63, kanti umqulu wesibili "Ingxenye Yokusebenza ye-DC" uhlukaniswe ngama-scheme angu-57.
Uhlelo lwesekethe olusizayo lwengxenye yokusebenza kwe-DC lusetshenziswa kakhulu ohlelweni lwesitshalo samandla esiphansi (isiteshi) sesitshalo samandla kanye nesiteshi esincane. Lufanele uhlelo lwesitshalo samandla esiphansi seyunithi olunamandla angu-200MW nangaphansi kanye no-300MW nangaphezulu, kanye nemodi yokulawula ejwayelekile yomugqa ongenayo wokunikezwa kwamandla okusebenza (oyisipele), umugqa wesiphakeli sokunikezwa kwamandla kanye nomugqa wesiphakeli semoto.
Uhlelo olusizayo lwengxenye yokusebenza kwe-AC lusetshenziswa kakhulu ohlelweni lwe-voltage ephansi yesiteshi esincane emafektri, ezimayini, emabhizinisini nasezindlini eziphakeme. Kunezinhlelo ezihlanganisiwe ezi-6 ezifanele ukulawula ukusebenza kokunikezwa kwamandla kabili, futhi kunezifunda zokulawula ezifana nokusebenza kokuzishintshanisa ngogesi kanye nokuzivuselela, ezingasetshenziswa ngqo ekwakhiweni kobunjiniyela.
Ugesi wokulawula we-DC yi-Dc 220V noma i-110v, kanti ugesi wokulawula we-AC yi-AC 380V noma i-220V. Ugesi wokulawula we-220v uthathwa kugesi wokulawula womphakathi ohlinzekwa yi-transformer yokulawula ekhethekile ekhabhinethi. Ugesi wokulawula womphakathi usebenzisa imodi engaguquki ukulawula i-transformer, kanti ugesi we-24V ugcinelwe ukusetshenziswa kwezibani zesignali zikagesi ezibuthakathaka. Ukuze uthole indawo yokufaka imitha yehora le-watt, indlela yokwethula i-voltage kanye nezinye izidingo zokufaka nokusebenzisa, sicela ubheke "imiyalelo yokuhlanganisa" yomdwebo wesekethe osizayo.
