Switchyard Panja (Substation)
Malo omwe switchgear ya booster station imalandira ndikugawira mphamvu yamagetsi yopangidwa kuchokera ku seti ya hydro-jenereta, ndipo chipangizo chamagetsi chamagetsi chamagetsi champhamvu kwambiri chimapereka mphamvu ku gridi kapena malo onyamula pambuyo pakukweza. Zimapangidwa ndi thiransifoma, switchgear, switch yodzipatula, inductor yolumikizana, chomangira mphezi, chipangizo cha basi ndi zomangira zofananira. Zimafalikira pamtunda wautali kudzera pa switchyard.
Itha kugawidwa m'magulu awiri: zida zogawa magetsi zakunja ndi zamkati malinga ndi malo oyika zida zamagetsi. Zida zamagetsi za 110kV ndi 220kV zimasanjidwa pafakitale zikaphatikizidwa ndi mawonekedwe a malo opangira magetsi opangira magetsi, ndipo mtunda wosiyanasiyana umakhala wocheperako poyerekeza ndi mawonekedwe akunja, kotero kuti deralinso ndi laling'ono. Mtengo wa zomangamanga ndi wapamwamba kusiyana ndi mawonekedwe akunja, ndipo nthawi yomangayo ndi yaitali, koma sichikhudzidwa ndi nyengo yoipa. Nthawi zina pofuna kuchepetsa ndalama zomanga, mbali ina ya zipangizozo imayikidwabe kunja kwa fakitale.
mankhwala Introduction
Chidule chachidule cha kapangidwe ka boost switch station:
1. High-voltage Circuit Breaker: Ikhoza kudula ndi kulumikiza mafunde opanda katundu ndi katundu wa mzere ndi zipangizo zosiyanasiyana zamagetsi pamene dongosolo likugwira ntchito bwino; Pofuna kupewa kukulitsa kukula kwa ngoziyo, Ikhoza kugwirizana ndi chitsimikizo cha relay kuti idule msanga cholakwika pamene dongosolo lalephera;
2. High-voltage Isolation Switch: Pofuna kuonetsetsa chitetezo cha zipangizo zamagetsi ndi zipangizo zamagetsi zokhala ndi mphamvu zambiri zimagwira ntchito yodzipatula pakati pa mabwalo panthawi ya ntchito yokonza, chosinthira chodzipatula chimatha kutsegula ndi kutseka dera lopanda katundu, ndipo sichitha. kukhala ndi ntchito yozimitsa arc;
3. Transformer Yapano: Imasintha mafunde apamwamba kukhala otsika kwambiri molingana. Mbali yoyamba ya thiransifoma yamakono imagwirizanitsidwa ndi dongosolo loyamba, ndipo mbali yachiwiri imagwirizanitsidwa ndi zida zoyezera, chitetezo cha relay, etc;
4. Voltage Transformer: Pofuna kuteteza, metering, ndi zida zogwiritsira ntchito, imasinthidwa magetsi apamwamba kukhala magetsi achiwiri a 100V kapena kutsika molingana ndi ubale wofanana;
5. Mphezi Arrester: Zomwe zimagwiritsidwa ntchito kuteteza zida zosiyanasiyana zamagetsi mumagetsi amagetsi ku kuwonongeka komwe kumachitika chifukwa cha kuphulika kwa mphezi, kuwonjezereka kwamagetsi, ndi kuwonjezereka kwamagetsi kwafupipafupi. Womangayo nthawi zambiri amalumikizidwa pakati pa waya wamoyo ndi pansi, womwe umalumikizidwa mofanana ndi zida zotetezedwa.
