Chosinthira cha FZRN25-12D/T630-20 chamkati cha AC HV ndi chipangizo chamkati cha magawo atatu a AC 50Hz ndi voteji yovomerezeka ya 12K. Chimagwiritsidwa ntchito pamalo ogawa mabizinesi amakampani ndi migodi ndi malo osinthira etc, chomwe chimagwiritsidwa ntchito kuteteza ndi kulamulira magetsi, kuyatsa ndi kutseka magetsi, kutseka magetsi, chosinthira magetsi cha zero load ndi kuyika magetsi a chingwe.
Pokhala ndi makina oyendetsera magetsi ndi ma electromotive, n'zosavuta kukwaniritsa zofunikira zitatu zoyendetsera magetsi.
FZRN25-12D/125-31.5 mtundu wa AV HV load switch - fuse combined electrical equipment ndi chipangizo chamkati cha magawo atatu a AC 50Hz ndi voltage yovotera ya 12KV. Chimagwiritsidwa ntchito pamalo ogawa malo opangira mafakitale ndi migodi ndi malo osinthira etc, omwe amagwiritsidwa ntchito powongolera katundu ndi kuteteza ma short circuit. Chosinthira chapansi chomwe chili ndi zida chimatha kunyamula ma short circuit current. Njira yoyendetsera magetsi yamanja ndi electromotive yamagetsi.
Chosinthira cha FZN25-12D ndi FZRN25-12D cholowetsa katundu ndi zida zamagetsi zophatikizika zimagwiritsidwa ntchito pa malo ogawa zinthu m'mizinda pogwiritsa ntchito neti ya ring net kapena rerminal supply ndi zida zamagetsi zamafakitale, zomwe zimagwiritsidwa ntchito powongolera katundu ndi kuteteza ma circuit afupi. Popeza zida zamagetsi zophatikizika zimabweretsa ntchito zodalirika komanso zoteteza zachuma ku zida zamagetsi za transformer etc, motero zimagwiritsidwa ntchito makamaka pa neti ya ring net, duble radiation supply unit ndi substation ya bokosi.

Magawo aukadaulo ndi miyeso ya kapangidwe kake

Kapangidwe ka Zamalonda ndi mfundo yogwirira ntchito

1. Chogulitsachi chimagwiritsa ntchito vacuum interrupter. Chimagwira ntchito bwino komanso chodalirika, chimakhala ndi nthawi yayitali yamagetsi, chimatha kusweka bwino, chimatha kupanga/kusweka bwino komanso chimatha kugwiritsidwa ntchito mosavuta komanso kukonza mosavuta.
2. Imaphatikiza thupi la switch ndi njira yogwirira ntchito, yomwe imaphatikiza cholumikizira, switch yoletsa katundu ndi switch yothira nthaka. Ndi yaying'ono komanso yokhala ndi voliyumu yaying'ono.
3. Makonzedwe ofanana a fracture yolekanitsa yogwira ntchito mwachindunji ndi vacuum interrupter, mphamvu yayikulu komanso yokhazikika ya kutentha; imatha kugwiritsidwa ntchito nthawi imodzi chifukwa cha njira zapadera zolumikizirana.
4. Kapangidwe ka koni yolumikizana yokhazikika, chivundikiro choteteza kutentha ndi chotseka zimatha kulekanitsa busbar ndi chosinthira choletsa kunyamula katundu kwathunthu.
5. Chosinthira cha vacuum load break, chosinthira cha earthing, shutter, ndi chitseko cha switchgear zimagwirizana ndi "5 prevention" mechanical interlock, zomwe zingalepheretse kugwiritsa ntchito molakwika ndipo ndizotetezeka komanso zodalirika.
6. Mphamvu yoyendetsedwa ndi makina ogwiritsira ntchito masika, kutseka ndi kutsegula chidebe pogwiritsa ntchito magetsi komanso ndi manja.
7. Voltage yogwira ntchito yotseka ndi kutsegula ikhoza kukhala DC ndi AC.
8. Mtundu wabwinobwino umagwiritsidwa ntchito ndi makina ogwirira ntchito akumanzere ndi akumanja, koma chidebecho chimagwiritsidwa ntchito ndi makina ogwirira ntchito akutsogolo monga momwe wogwiritsa ntchito amafunira.
