I-XGN15-24 BOX-TYPE FIXED AC METAL-ENCLOSED SWITCHGEAR

imininingwane yomkhiqizo

Uhlolojikelele

I-DR-XGN-24 ibhokisi lohlobo lwe-AC metal switchgear yenethiwekhi yendandatho evaliwe iyisizukulwane esisha se-sulphur hexafluoride load switches, engacushwa ngama-circuit breaker, ama-switch switch ahlukanisayo, ama-transformer amanje, ama-voltage transformer, izibambisi zombani nezinye izakhi zikagesi. Ikhabhinethi yonke ifakwe umoya futhi ilungele ukusabalalisa amandla okuzenzakalelayo. Kuyi-switchgear ehlanganiswe ngensimbi futhi enwebekayo. Inezici zokubukeka okuhle, isakhiwo esilula, usayizi omncane, ukusebenza okuguquguqukayo, nokuxhuma okuthembekile.

Le khabhinethi yenethiwekhi yendandatho ifanele izigaba ezintathu ze-AC 50Hz, isistimu kagesi elinganiselwe ye-voltage engu-12kV, futhi isetshenziswa kakhulu kumanethiwekhi endandatho yezimboni nakumakhebula omphakathi kanye namaphrojekthi okugcina amandla. Ifaneleka ngokukhethekile kulezi zindawo ezilandelayo: ukusatshalaliswa kukagesi ezindaweni zokuhlala zasemadolobheni, iziteshi ezincane zesibili, amahhovisi okushintshanisa, amabhizinisi ezimboni kanye nezimayini, izitolo ezinkulu, izikhumulo zezindiza, imigwaqo engaphansi komhlaba, imigudu, ukukhiqizwa kwamandla omoya, njll.

Izici eziyinhloko zomkhiqizo

◆Khulisa umthamo we-transformer enkulu futhi uthuthukise umthamo wokuphakelwa kukagesi wesiteshi esincane.

◆Ukuthuthukisa amandla okudluliswa kwamandla ezintambo zokusabalalisa nokunciphisa inani lezintambo zokusabalalisa.

◆Khulisa irediyasi yokuphakela amandla kwezintambo zikagesi ezimaphakathi.

Leli zinga le-voltage lihlolwe endaweni encane ngaphambili. Ngokwesicelo se-State Grid Corporation yase-China, izinga lamandla kagesi angu-20kV lathuthukiswa ngendlela yokuhlola esiFundazweni sase-Jiangsu. Manje i-China Southern Power Grid nayo isilungiselela ukukhuthaza izinga lamandla kagesi angu-20kV e-Guangdong nakwezinye izindawo. Kungabikezelwa ukuthi ekugcineni imishini ye-24kV izobusa emakethe.
